Use Technology to Succeed at Job Interviews

Are you scheduled for an interview for what could potentially be your dream job? Whether you’re a seasoned executive or recent college graduate with a degree in computer engineering, an interview can triggers feelings of excitement coupled with anxiety. Follow these recommendations from the Human Resource professionals to ensure your interview experience is successful.

There are several key points to keep in mind even before you begin to prepare for the interview. Remind yourself that you would not have been scheduled for an interview if your qualifications and experience level did not meet the requirements for the position. Furthermore, not only is the interview an opportunity for the hiring manager to determine your fit with the existing team and company culture, but it is also an opportunity for you to assess whether this is a company and position that fits with your work style and career goals.

When preparing for an interview, one of the most important steps to take is to research the company by reading through all the pages on their website and keeping track of questions to pose at the appropriate time during the interview process. Check out the online reviews of the company left by customers, vendors, current and prior employees to get a picture of the company’s culture and responsiveness.

Professional attire is always recommended for an interview. Select a classic, well-tailored suit or quality blazer and dress trousers. Leave the wild colors and excess bling for the weekends. You only have one opportunity to make a first impression. Tone down your hairstyle and makeup and remove any facial jewelry if you are applying for a professional position. Take advantage of the awesome deals offered by Groupon coupons and select from the huge variety of professional styles available from Nordstrom.  The most important things to wear to a job interview are a quiet self-confidence and genuine smile.

Plan to arrive at least fifteen minutes prior to your scheduled interview time. Greet the hiring manager with a warm smile and firm handshake. If you ascertain during the interview that this is indeed a position you would like to have, let the hiring manager know you are interested in joining the team. On the same day of the interview, hand-write a note thanking the hiring manager for their time and mail it. Best of luck to you!

What Are the Different Types of Computers?

These days, computers are described using many different terms. In most cases, simply the capability, the expected use or the size of the computer is implied. However, what most of us do not know is that there are actually different types of computers.

Types of Computers

1. PC

A computer designed to be used by a single person is defined as a personal computer (PC). While a Mac is a personal computer, systems running the Windows OS are considered PCs by most people. Initially, personal computers were referred to as microcomputers because they were complete computers with a smaller size. The Apple iPad is a perfect example of a modern PC.

2. Desktop

A desktop computer is a personal computer that is not designed to be portable. Generally, desktop computers are set up in permanent locations. In comparison to portable computers, more versatility, storage and power is offered by most desktop computers for a lesser price.

3. Laptop

Laptops, also known as notebooks, are small-sized portable computers can be placed on the lap and used there. The display, hard drive, keyboard, memory, processor, and a trackball or point device are integrated in a battery-operated package.

4. Netbook

Netbooks are also portable computers but they are much smaller than typical laptops. In comparison to brand-new laptops that can be found at retail outlets, netbooks are much cheaper, usually starting from $300 to $500. However, the internal components of netbooks are not as powerful as those in most laptops.

5. PDA

PDAs or Personal Digital Assistants are integrated computers that do not use a hard drive but instead, use flash memory for storage. These are touchscreen devices and do not have keyboards. Typically, PDAs are very lightweight, smaller than a paperback novel and have a decent battery life. The handheld computer is a slightly heavier and larger version of the PDA.

6. Workstation

A workstation is another type of computer. A workstation is just a desktop computer with additional memory, a more powerful processor, and enhanced capabilities to perform a special group of task, like game development, or 3D graphics.

7. Server

Servers are computers that have been optimized to provide services over a network to other computers. Usually, servers have large hard drives, lots of memory and powerful processors.

8. Mainframe

At one time, mainframes used to be computers that were so huge they would fill a whole room or even an entire floor. As the power of computers has increased while their size has decreased, mainframe computers are now referred to as enterprise servers.

9. Supercomputer

The price of a supercomputer can be anywhere from hundreds or thousands to millions of dollars. Majority of supercomputers comprise of multiple high-performance computers that work in parallel as one single system. Cray Supercomputers have built the well-known supercomputers.

10. Wearable Computer

Wearable computers are a latest computing trend. Today, typical computer applications, like calendar/scheduler, database, e-mail and multimedia have been integrated into cell phones, clothing, visors and watches.

The Ways That Renting a Computer Will Save You Money

If you are looking for ways to save money, computer rental is definitely something that you should consider. Not only is it far cheaper to rent a computer than to buy one outright, you can also save yourself money on finance charges, upkeep, maintenance and the headaches involved with owning a brand new laptop or personal computer.

12 Ways Renting a Computer Will Save You Money

There are so many ways to save by computer rental instead of purchasing laptops or a desktop computer that it would be difficult to list them all here. However, the following twelve ways that you save by choosing computer rental should give you an idea of the kinds of savings you are looking at.

  • Renting a computer is cheaper. Instead of having to come up with hundreds or thousands of dollars out-of-pocket, you can spend a set amount every month.
  • When you rent a computer you don’t have to worry about the pesky finance charges that so often come attached to computer credit accounts. All the costs are in your monthly rental fee.
  • Computer Rental is better for the environment. By recycling computers you can cut your carbon footprint on the planet.
  • By renting a computer you are acting responsibly from a social perspective. Computers are often made by underpaid employees in overseas factories. Reducing the need for this kind of exploitation is acting socially responsible.
  • Renting a computer instead of buying means you don’t have to spend money on upkeep. Anything that goes wrong with a computer rental, even with the computer hardware is maintained by the rental agency, which will make sure that it gets fixed.
  • When you rent a computer you don’t have to worry about upgrading your computer. Rental computers are upgraded regularly. If you are renting your computer for the long-term, you are sent upgrades as part of your rental policy.
  • You don’t have to worry about your computer becoming obsolete. When you are renting a computer the rental agent will make sure that your computer stays viable. If a computer that you are renting becomes obsolete, then
  • When you rent a computer, you do not have to buy your computer accessories separately. They come with the cost of the rental.
  • If you get bored with your rental PC you can trade it in for another model such as a gaming pc.
  • Ready for an upgrade? Say you want something more powerful than your current model, like something that manufacturers have come up with. By turning in your old model and signing a new contract you can get an upgraded computer without having to spend hundreds of dollars out of pocket.
  • You can choose to rent other equipment as well. If you should, say, want a projector or other piece of equipment, you don’t have to buy those outright either. You can add the cost of renting the projector, even if it is for a short time, to your monthly computer rental bill.
  • Finally, you don’t have to worry about maintaining a warranty to have your computer fixed. The rental agency keeps the repairmen on staff and keeps you from having that extra charge.

Best-Paying Computer Degrees

Beating all odds stacked against them, computer degrees seem to have regained favor with students. At least that’s what the data released by the Computing Research Association (CRA) suggests.

According to the CRA Taulbee Survey report, Computing Degree and Enrollment Trends, 2010-11, enrollments in undergraduate computer science degree programs rose 9.6 percent in the 2011-12 school year. This was the fourth straight year of increased enrollments in computer science degree programs*.

The increase in demand for computer degrees among students indicates a corresponding growth in computer-related careers that can be monetarily rewarding, personally fulfilling, and intellectually stimulating. Here’s a selection of some computer degree programs and the careers they can lead to:

1. Computer Science Degree: The computer science degree has been ranked among the top ten undergrad college programs by salary in a 2011-12 college salary report published by According to the report, computer science graduates earn a starting median pay of $56,600, and by mid-career, it can go up to $97,900, depending on location, education, and experience**.

And what kinds of career can you pursue once you graduate from this program? Computer science graduates have the option of choosing from a variety of exciting careers.

For instance, software engineers are responsible for designing and developing software applications that allow people to complete specific tasks on the computer, while an information systems manager or information technology manager plans, coordinates and directs computer-related activities in an organization.

2. Computer Programming Degree: Like the name suggests, a computer programming degree is focused on training graduates in various programming languages and providing them the skills to keep learning new languages as and when they are developed. This degree program can be pursued at both the associate’s and bachelor’s levels, depending on your personal and professional aspirations.

A computer programming degree prepares graduates for the role of a programmer, who writes the code needed to convert the designs developed by software engineers into actual software applications. They do this by writing a series of instructions using a programming language such as Java or C++ that the computer can follow.


What Is Cloud Computing In Layman Language?

Subhash was a smart, innovative and self-starter, 23 yrs old guy who started a small business with his limited budget. He always wanted to curtail the business expenses smartly and wanted to opt for smarter investment techniques. In the initial phase of his business he noticed he faced some really expensive and severe challenges. He enlisted the top challenges and one of them was buying hardware for each employee along with the software and their licenses which he discovered were extremely taxing. Moreover he detected other problems like storage capacity, keeping updates for newest software and ongoing trends in the market. He felt with every new hire more software were needed, such problems worsened the situation and distracted him from the goals of his business. He researched and finally chose Cloud computing- A smart and user friendly choice which is easy on pocket too.


In the earliest of days when Homo sapiens grew, they beautifully transformed themselves as humans from apes. Grew a little: understood basic needs- Food, clothing, shelter. Grew more- found mediums to fulfill those basic necessities. Then they started ‘Developing’, now they had farms for food, wells for water, mills for clothes, bricks for homes. Necessities give birth to utilities. Same scenario applies for business computing. One of the newest successful utility is Cloud Computing. Traditionally companies built their own in-house IT infrastructure catering to all the technical needs. But that involved expensive equipment and servers and installed everything locally – too much of hard work involved to make the ends meet! Things have changed. With the dawn of cloud computing a company can have a reliable and a safer business computing delivered like a utility service. We buy basic utilities for smooth functioning of our day to day lives, similarly we ‘BUY’ IT infrastructure as a service! Just spend for what we need and focus on the business not the technology.

Technically- What is cloud computing?

Cloud computing is the provision that allows the user to log into a web based service which hosts all the programs obligatory for completing the job. The cloud computing service provider runs everything ranging from emailing to word processing to different complex data analysis programs. The term ‘cloud’ actually refers to the network of computers which handle all the assigned respective tasks. Cloud computing service providers charge for the Maintenance and management of data inputs by clients. Cloud computing has emerged as the next big thing in the dome of application software, storage, hardware and platform flexibility that provides easy solutions to the most complex of things! The system favors all sizes of business but proves really fruitful for middle and small sized ones.

All one needs to avail the service is a basic computer system, web browser and the internet. It has become the lifeline of organizations who seek a simple solution to the compound problem of choosing and organizing software as per each employee’s area of work. Have you ever noticed every internet user prominently benefits from cloud computing? The finest examples of cloud computing are Gmail, Amazon web services, Google applications where a browser helps the user to access the application whenever she/he feels like.

How it works?

Knowing how cloud computing works is interesting. The structural design can be categorized into two main sections: Front end and back end. Front end is controlled by the end user or client or say the web browser who uses the cloud services. Back end is the network of servers with any computer program and data storage system that runs, handles and maintains the cloud (Succinctly- The service provider).

Cloud has a centralized server administration system. The centralized server administers the system, balances and adjusts client supply and demands, monitors traffic and avoids congestion. This server follows a set of rules (protocol) known as middleware. Middleware as the name suggests, is the intermediary that allows networked computers to communicate with each other. Observing the other side of the process one can rename cloud computing as green computing because it helps in successful conservation of power energy.

Can Cloud computing be pocket friendly?

Cloud computing is cost effective too. Unlike traditional computing, the service condenses “Hard Costs” like cost of hardware, infrastructure, software licenses, and “Soft costs” such as IT staffing, troubleshooting, energy costs to run the servers, desktops and cooling the entire server room. As far as data maintenance costs are involved they too are quite reduced as they are maintained by the service provider (They perform the complete set of tasks; from running the cloud to storing data). The need to high storage hard drives can be snubbed away as all the data is stored on a remote computer.

Breakdown of the system can cause the owner a serious nervous breakdown because of high data recovery and system repair costs, not to ignore the data loss. In such situations, of course the show goes on because the data can be operated from the remote computer from any place!

Market is in the favor of buyer. Since past three years number of service providers has swelled. In this computing arena we have crucial players like Microsoft, Google, Amazon, Intel, and many others who are competing hard to build effective and impressive clouds for their clients..

What to Do If Your Computer Does Not Start

1. No Access to the Keyboard During the Boot Process?

Help, I can’t access my keyboard at boot!

If this is the case, I would recommend:

1-1. If using a USB keyboard, plug the keyboard into the primary USB ports on the back of the computer (on the motherboard). Restart the computer and try again.

1-2. Try another known working USB keyboard plugged into the primary USB ports on the back of the computer (on motherboard). Restart the computer and try again.

1-3. Try another known working PS/2 keyboard, restart the computer and try again.

1-4. If using a PS/2 Keyboard, try replacing your keyboard with a USB keyboard, restart the computer and try again.

1-5. If these steps fail, remove your keyboard connection and shut the computer off with the power button. While computer is off, plug the keyboard back into the computer and start the computer.

Still doesn’t work? Please go to “I need to flash my bios” section and proceed with flashing your bios.

2. Does Your Computer Freeze at Bios?

Why is my computer frozen?!

2-1. Remove all devices from your computer including removable hard drives, additional USB devices, and printers and faxes. Restart the computer and try again. If no result, go to step 2-2.

2-2. If you can see your bios screen, please tap the key to go into your bios settings. While inside of bios, make sure that your hard drive, memory and video card ( is applicable) are detected. If it is not, try re-seating or replacing the unit that is not being detected. If no result, go to step 2-3.

2-3. While looking in bios and all of your hardware is getting detected okay, please reset the bios back to its default settings and choose “save and quit.” The computer will restart and you should be looking at the operating system loading page at this point. If no result, go to step 2-4.

2-4. Open the computer, remove all but 1 memory module (usually closest to the CPU) and disconnect all hard drives. Also disconnect and PCI or AGP add on cards and start your computer. If you see “operating system not found” or a similar message, progress has been made. Then start adding back 1 item at a time, restarting the computer after each item to see when it fails.

How to Build a Computer and Component Selection

I get asked the same question very often, how to build a computer? It can be very deceiving to the average person’s eyes when they glance into an open computer. There are different “pieces” to be found and quite a few wires running around from one part to the next. All of this can be quite confusing and discouraging. The best advice I can give is that it looks more complicated that what it actually is. Don’t be afraid to do some trial and error to figure things out, within reason. Of course you have to be careful and not force components in spots they do not belong, but it is difficult to mix up as most things can only go one way, and will only fit in the correct location. Over the years it is how I learned most of what I do today, trial and error. One something goes wrong, there is always a way to fix it, and sometimes it just takes some patience and research to figure out a way to fix the problem.

I started building computers around 1996, when I was ten years old, and it became a hobby of mine which led into a business about 16 months ago. Over the years there has been a lot to learn and pick up on, and that is the thing with technology and computers. Computers are always changing and updating for more performance, reliably, smaller size, ease of use and less energy consumption in more recent years to become “green” on the environment.

But that is enough with the history, it is now time to move onto the actual computer building process from start to finish. There is quite a bit to cover and there are many ways to go about the process, but I will share my personal views and opinions along the way.

To start things off you have to ask yourself what you want the computer for. It could be a basic machine for simple web browsing, such as Facebook and E-mail. Another need could be simply for a media center, a computer hooked up with an entertainment center for movie watching purposes, music, recording, and internet television as well as any other uses hooked up to a television full time. The machine may be used primarily for gaming. A gaming computer can be a touchy subject as everyone’s views are different. Some may just be happy with playing a game on lower setting, and others may want everything turned up to the max with room to spare for future game titles. The final use I will touch into would be photo and video editing. A lot of times a high end gaming computer, and a photo/video editing machine will have many similarities. You do not necessarily have to have an extremely powerful system for videos and photos, but it will certainly cut down on the time required. If someone is looking to produce lengthy videos, it could take ages to accomplish on a less powerful computer. One thing I will say is no matter what you are looking to build a computer for, figure out a budget of available funds and go from there. There is no sense in looking at very costly premium components, when there is just no budget for it. Many would be quite surprised at how inexpensive a fairly powerful system can be “now days.” I never recommend to buy the latest and greatest as it will cost a premium and will be replaced by something better in around six months’ time. That is just how the computer world works.

Why You Get Eyestrain and the Need for Computer Glasses

Computer eyestrain is the number one office-related health complaint in the U.S., with some 60 million Americans suffering from computer eyestrain according to the American Optometric Association. Computer use at work and home continues to grow exponentially. Computer use is associated with a number of visual and physical symptoms experienced by 50%-90% of all computer users. So, if you have experienced fatigue, headache, eye strain, blurred vision, dry or irritated eyes and neck or back aches at the computer it is possible that you are suffering just some of the symptoms called Computer Vision Syndrome (CVS). Solving the symptoms of CVS requires a visit to your eye doctor to determine if you need corrective lenses while working at the computer, especially if your computer use is two or more hours a day. The reason for computer vision related problems is further explained with a simplified description of how the eye and brain processes visual information.

Working at a computer is more visually demanding than doing other standard office work such as reading printed documents. Human vision is not designed for staring into a computer screen. Your eyes require constant sharp edged images like the characters found on ink and paper to process and focus on comfortably. The eye system of lens focusing is referred to as accommodation. Computer images are made up of tiny round dots, known as pixels. Since your eye cannot focus on the tiny round pixels, you must constantly refocus or accommodate to keep the images sharp. The eyes can’t keep a constant relaxed focus on the computer screen, even when you increased the number of pixels per square or max out the computer’s refresh rate. The monitor is constantly being “redrawn”, and this eventually leads to repetitive stress of the eye muscles and fatigue.

Bifocals are not helpful at the computer. In fact, the bifocal only increases the problem since the reading portion of the bifocal is designed for a shorter distance than a computer screen and for a much lower visual angle. The tendency to lift the chin up and move closer to the screen just leads to lower back and neck problems. Progressive lenses (eyeglasses without bifocal lines) have the same shortfalls since the area for intermediate computer vision is found in the lower half of the glasses and the area for viewing is limited.

If you spend two or more hours working at the computer CVS can be a real problem at home or in the workplace. Savvy employers are beginning to recognize that increase work production can be realized with eyewear designed for computer use. Visit your eye doctor who is ready to help you eliminate the problems of Computer Vision Syndrome with a dedicated pair of computer glasses. You can benefit from a natural head and neck position with computer glasses or the new ergonomically designed clip-on computer reading glasses.

You can choose to have a dedicated pair of computer glasses custom made or you may be wondering how to convert your existing general purpose pair of eyeglasses that you use for distance and reading only into computer glasses. Well, there is an easy and affordable way by using a new innovative clip-on lens to view a computer monitor. Simply clipping the lens on to the bridge portion of your general wear eyeglasses that you are already wearing, and you can immediately feel and see the difference while working on a computer. Save your eyes from nagging eyestrain and improve your ability to be productive in the workplace as well. A pair of dedicated computer glasses or the new clip-on computer reading glass will do much for you in all aspects of work, as well as and make you a feel better outside of work since they will eliminate much of the eyestrain, lower back discomfort and neck pains that you are experiencing.

What Is Computer Speed Memory?

Increase Computer Speed Memory by Increasing the Ram (Memory)

Did you know that if you increase the memory on your computer, you can increase the speed? When you try to open a program on your computer, it needs to load itself from the hard drive into the memory. If the memory resources are low because there are too many programs open at the same time, or you have too many programs on your computer, this all takes memory to make things happen. The result will be a computer that runs very slow.

Nobody likes working with a computer that is slow. To have a computer that performs with speed, making the action process happen in 2-5 seconds, it is important to have ample RAM (memory) installed on your computer for computer speed memory. Many of the older computers might have 1 Gigabyte of memory if they are lucky, usually less. This is way too low by today’s standards. You should have a minimum of 5-6 Gigabytes of RAM and preferably 8-10 Gigabytes if you can afford it.

Each action performed, every program installed, takes up and uses computer memory. Don’t overload your computer. You can combat that by increasing the memory (RAM). Freeware contributes to a slow computer because it quite often comes bundled with other freeware that is installed on your computer. Many of those programs are just using up memory and are never used.

Tips for Computer Speed Memory Performance

There are several tips you should be aware of for computer speed memory to keep your computer running at maximum speed. Having the proper security programs on your computer is a must. If you try to shortchange yourself and your computer by not installing these mandatory programs just to save some money, you will ultimately pay the price down the road.

Security programs guard your computer against viruses such as worms, Trojan horses, adware, spyware, malware and other damaging viruses (just to name a few), to your PC. Use the best antivirus software, and keep it updated by version and daily updates. There is a constant new supply of viruses that attack your computer on a daily basis. Keeping all your programs updated, especially your security programs, should keep your computer protected.

Cloud Computing – Is It Safe?

There are essentially two kinds of computing environments:

On-premises computing is the traditional form of computing in which you or your company own and manage your own systems. All the applications you use, as well as your data files, are in your own computers on your own premises either on individual PCs or on an in-house local area network.

In cloud computing, by contrast, your applications and files are held remotely on the Internet (in cyberspace) in a network of servers which is operated by a third party. You access applications and work on your files from your PC simply by logging on to the network.

Cloud services are provided by cloud-hosting providers, companies such as Google, Amazon, Oracle Cloud, Rackspace, Microsoft Azure, and so on.

There is nothing fundamentally new about the concept of cloud services. If you are using Gmail, Hotmail or yahoo for your emails, you are using cloud services and probably have been for years.

What is relatively new is the types of services that are being offered in a cloud-environment. These now go far beyond email to cover all the IT services that an on-premises computing environment would deliver, such as accounting, marketing, human resources and so on.

Advantages of cloud computing

Cloud computing has several advantages over on-premises computing:

1) You can run an application or access your files from anywhere in the world using any computer.

2) Cloud computing is cheaper.

3) You need less technical knowledge.

4) Cloud computing delivers a better performance.

5) Cloud computing is eminently scalable. Increasing the number of applications you use or the amount of data you store does not require a heavy investment; you only need to advise the cloud-hosting adviser.

Given these advantages it no surprise that over the last few years there has been a widespread rapid adoption of cloud computing. Analysts estimate that the growth rate of all spending on cloud IT will soon be at least four times faster than the growth rate of all spending on on-premises computing.

Indeed, analysts are expecting the annual growth rate of spending on cloud computing to average 23.5% compound from now until 2017. In addition, by that year spending on cloud services will probably account for one-sixth of all spending on IT products, such as applications, system infrastructure software, and basic storage.

Given the rapid growth in cloud computing, the big question, of course, is whether cloud computing is safe. Is it more or less safe than on-premises computing?

The short answer is that cloud computing is not less safe than on-premises computing. However, the threats are somewhat different in nature, though they are converging.
