How are computers classified?

Answer 1

There is no one answer to that question
It depends on the classification criteria
- If it is classified on computation abilities: Then range would span all the way from handheld devices, to desktops, to supercomputers. This is also the right place to worry about single/dual/quad core processors in which case
- If memory was the issue: Then here again, from handheld devices to desktops to mainframes/databases etc
- If you are worried about graphics: Then you need to understand graphics cards etc.
- Some specific things also need classification based on on board chips, but this possibly gets into the realms of DSP
- Some people distinguish between OS, but then some dont

Specifically the classification depends on your point of view or requirement. I could have answered better if you had provided more insight into what you actually want!

Answer 3

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. So here is a classification of computers for you to understand the difference.
They can also be classified in different ways like classification of computers by size. All the computers are designed by the qualified computer architectures that design these machines as their requirements. A home computer 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.
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 Hollywoods 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 instructions per second and is capable of accessing billions of data. This computer is commonly used in big hospitals, air line reservation 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 thousands of dollars.
Minicomputer
This computer is next in line but 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.
