Classification of Computer Presentation Transcript:
1.Classification of Computer
2.The digital computers that are available nowadays vary in their sizes and types. The computers are broadly classified into four categories (Figure 1) based on their size and type-
(1) Microcomputers
(2) Minicomputers
(3) Mainframe computers, and
(4) Supercomputer.
3.Classification of computers based on size and type
4.Microcomputers
Microcomputers are small, low-cost and single-user digital computer. They consist of CPU, input unit, output unit, storage unit and the software. Although microcomputers are stand-alone machines
They can be connected together to create a network of computers that can serve more than one user. IBM PC based on Pentium microprocessor and Apple Macintosh are some examples of microcomputers. Microcomputers include desktop computers,
5.Notebook computers or laptop, tablet computer, handheld computer, smart phones and netbook
6.Microcomputers
7.Desktop Computer or Personal Computer (PC):-
is the most common type of microcomputer.
It is a stand-alone machine that can be placed on the desk. Externally,
it consists of three units—keyboard, monitor, and a system unit containing the CPU, memory, hard disk drive, etc. It is not very expensive and is suited to the needs of a single user at home, small business units, and organizations. Apple, Microsoft, HP, Dell and Lenovo are some of the PC manufacturers.
8.Notebook Computers or Laptop:-
resemble a notebook.
They are portable and have all the features of a desktop computer.
The advantage of the laptop is that it is small in size (can be put inside a briefcase), can be carried anywhere, has a battery backup and has all the functionality of the desktop. Laptops can be placed on the lap while working (hence the name). Laptops are costlier than the desktop machines.
9.Netbook:- These are smaller notebooks optimized for low weight and low cost, and are designed for accessing web-based applications. Starting with the earliest netbook in late 2007,
they have gained significant popularity now. Netbooks deliver the performance needed to enjoy popular activities like streaming videos or music, emailing, Web surfing or instant messaging. The word netbook was created as a blend of Internet and notebook.
10.Tablet Computer:-
has features of the notebook computer but it can accept input from a stylus or a pen instead of the keyboard or mouse. It is a portable computer. Tablet computer are the new kind of PCs.
Handheld Computer or Personal Digital Assistant (PDA) :-
is a small computer that can be held on the top of the palm. It is small in size. Instead of the keyboard, PDA uses a pen or a stylus for input. PDAs do not
