Discuss What Are The Major Types Of Computer We Have Today?

COMPUTER TYPES: Once there was time when computers where physically two big and where placed in whole building but as time passed there are many revolutions in this field and computers gets Compaq in size. Following are some of the types of computers.

(1)Main Frame computers: The main frame computers are very large in size and also very difficult to operate a layman can't handle main frame computers these computers are specially designed for heavy processing because it can process millions of tasks in the matter of milliseconds. This kind of system is usually purchased by the large organization.

(2)Micro computers: The most commonly used computers in today's world are micro computers which you find in schools, offices, and homes etc, these computers are normally known as PC (personal computers) or desktop computers, PDAs (personal digital assistants) notebook computers, Laptops, Palmtops etc are some of its other types. These computers called micro because of its small size and used for daily routine work, these computers are not designed for heavy processing.

(3)Mini computers: This computer category is superior to micro computers and less in power from mainframe computers but and can handle handsome amount of processes at compatible speed.

(4)Embedded computers: The very important category of computers which are generally used in industries for automated work. They have most complicated type of Artificial Intelligence programming that controls different processes the ATM (automated teller machines) is one of the simple example of embedded computers.

(5)Portable Data Entry terminals: In short this category is known as PDETs which stores data from main frame computers to which they are linked and they are physically away from there source e.g. Magnetic Stripe readers, scanners, optical character recognition etc.
