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 payscale.com. 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.

Flashback

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..
