Characteristic of computer

Speed:

computer can perform very complex calculations at very enormous speed. generally, the speed of computer is measured in terms of fraction of speed.

Millisceonds-One thousendth of a second(1/1000).

Microsecond-One millionth of a second (1/1000000).

Nanosecond-One billionth of a second (1/1000000000).

Picosecond-One trillionth of a second (1/1000000000000).

Storage:

A computer system can store a huge amount of information which may be

used as future refresh. Few storage devices are Hard disk, CD-ROM.

Pen derive etc. The storage capacity is measured interims of :

8bits 1 Byte

1024 Bytes 1 Killobyte

1024 Kilobytes 1 Megabyte

1024 Megabytes 1 Gigabyte

1024 Gigabytes 1 Terabyte

Accurancy:

Computer always perform its takes without makieng any mistake if the instruction is

provide correctly. So the accurancy of a computer is cent percent.

Versatility:

Computer has a wide range of application and is used indifferent fields such as education

Science & technology, astronomy, business, entertainment. medicinies etc.

Diligence:

Copmuter is capable of doing the required tasks again without affecting its speed,

accuracy and efficiency.

Non-intelligent

Copmuter is a dumb machine and it cannot do any work without instruction from the user. So a computer cannot take its own decision as we can

Definition of computer

Computer is an programmable machine. computer is an electronic machine which can accept row material data and process then give instruction. Today, however, the term is most often used to refer to the desktop computer and laptop computer the most people use. Complex computer also include the means for storing data(including the program which is also a form of data) for some necessary duration. A program, be invariable and built into the computer(and called logic circuitry as it is on microprocessor) or different different program may be provide the computer. (loaded into its storage and then start by an administration or user). When referring to a desktop model, the term "computer" technically only refers to the computer it seat -- not the monitor, keyboard and mouse.

The main characteristic of a computer are:

• It responds to a set of instruction provided from an input device.
• It process the provided set of instruction
• It gives out the meaningful result after processing the instruction.
