Computers are available in different shapes, sizes and weights, due to these different shapes and sizes they perform different sorts of jobs from one another.

They can also be classified in different ways. All the computers are designed by the qualified computer architectures that design these machines as their requirements.

A computer that is used in a home differs in size and shape from the computer being used in a hospital. Computers act as a server in large buildings, while the computer also differs in size and shape performing its job as a weather forecaster.

A student carrying a laptop with him to his college is different in shape and size from all the computers mentioned above.

Here we are going to introduce different classifications of computers one by one. We will discuss what are in classifications and what job they perform.

Super computer

The biggest in size, the most expensive in price than any other is classified and known as super computer. It can process trillions of instructions in seconds. This computer is not used as a PC in a home neither by a student in a college.

Governments specially use this type of computer for their different calculations and heavy jobs. Different industries also use this huge computer for designing their products.

In most of the Hollywood’s movies it is used for animation purposes. This kind of computer is also helpful for forecasting weather reports worldwide.

Mainframes

Another giant in computers after the super computer is Mainframe, which can also process millions of instruction per second and capable of accessing billions of data.

This computer is commonly used in big hospitals, air line reservations companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis.

This is normally to expensive and out of reach from a salary-based person who wants a computer for his home.

This kind of computer can cost up to thousands of dollars.

Minicomputer

This computer is next in he line but less offers less than mainframe in work and performance. These are the computers, which are mostly preferred by the small type of business personals, colleges, etc.

Personal computers

Almost all the computer users are familiar with the personal computers. They normally know what the personal computer is and what are its functions.

This is the computer mostly preferred by the home users. These computers are lesser in cost than the computers given above and also, small in size; they are also called PCs in short for Personal computers.

This computer is small in size and you can easily arrange it to fit in your single bedroom with its all accommodation. Today this is thought to be the most popular computer in all.

Notebook computers

Having a small size and low weight the notebook is easy to carry to anywhere. A student can take it with him/her to his/her school in his/her bag with his/her book.

This is easy to carry around and preferred by students and business people to meet their assignments and other necessary tasks.

The approach of this computer is also the same as the Personal computer. It can store the same amount of data and having a memory of the same size as that of a personal computer. One can say that it is the replacement of personal desktop computer.

This is the information age. The advent of the Internet has made global communication inexpensive and available to everyone. It has affected the very way we communicate and transact. The information age has made businesses compete in an almost level playing field. These days, you can have your website optimized by an SEO expert so that the website can even be read in welsh. We are in the days where we can purchase things using our personal computer, where we can talk, hear and see loved ones or ones we want to love over web cameras. The convergence of technology has made cell phones become almost a part of us and overseas telephone communication cost has gone down especially with telephony and the like. We are all connected in that sense and the cost of personal computers have gone down to sub 1000 dollars and even sub 500 dollar levels. You can even get a pretty good net book for less than 500 dollars. The question is if we are too dependent on technology these days?

The answer is: it depends. We have used technology to make more informed choices in so many fields. Because of technology, there is less need for invasive surgery to see which areas need to be repaired. Scanning technology has enabled doctors to see inside of men and in three dimensions, giving them a clearer and better picture of the diseased part. In this area, technology has been helpful. In another matter, the answer is yes. The use of calculators has made us lazy to add, subtract and divide and it has in one sense, made us spoiled. It has however expedited matters and made us more efficient in calculating in areas in astro physics and quantum mechanics. With the aid of technology, man has ventured into space and beyond.

Has technology been helpful to society in general? Technology is a double edged sword and it can be used for good or evil. In this sense, technology is and will always be a tool, an aid for man. It is perhaps up to man to do whatever he wishes to do so. The Internet was initially developed for military purposes as a way to detonate a bomb or launch a missile when all forms of telephone communications were down. The Internet would find a way through a series of nodes and communication channels, most of them submerged in the ocean through submarine cables, to enable someone to launch something. Now, from the military usage, the Internet has become a global library, a communication tool, an instant post office, and even a buying station. It is what it is for we make it what it is.
