Computers are classify according to: Purpose Type of Data Handled Capacity 3. The classification of generations has been done based on technology, speed, storage, reliability and cost. Introduction to Computers . The History of Computers The history of computers is interesting perform many types of calculations Computer, Its Classification Generation of Computer vary in their sizes and types. In terms of power, nowadays high-end models of the Macintosh and PC offer the same computing power and graphics capability as low-end workstations by Sun Microsystems, Hewlett-Packard, and Dell. 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. Computers are classified into various types based on historical development (computer generation), purpose, technology used, and size & storage capacity. This chapter introduces the student to what a computer is, classifies computers into different categories, compares the different classes of computers and also introduces the keyboard as as a basic input device. Laptop: - this computer is similar to a desktop computers but the size is smaller.

The computers are broadly classified into four categories based on their size and type : (1) Microcomputers, (2) Minicomputers, (3) Mainframe computers, and (4) Supercomputer. Palmtop A small computer that literally fits in your palm. The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. A computer can be as big as an entire room or as small as a microcontroller found in mobiles and embedded systems. The set of instructions is called Program and can be written using artificial languages like Basic, FORTRAN, C, C++, Java etc. Computers classification*** Computers can be generally classified by size and power as follows, though there is Considerable overlap: • Personal computer: A small, single-user computer based on a microprocessor. Mini Computers Mini computers were introduced in the 1960s. XT (Extended / Extra Technology) Computer : The computers that use 8086, 8088 microprocessor are called XT computers. A PC can be defined as a small, relatively inexpensive computer designed for an individual user. 10 Types of Computers find this file in PDF format on our class CMPE12 1) History of Computers.
