History Of Computer

Histrory of computer

computer is the most powerful device that man has ever made it has made a great impact on our everyday life consider the statement everything is in computer does it sound like an hour statement no this statement is true nowadays everything is in computer means any information. you can get easily with the help of computer and its technology. That's why everything is in computer and as result computer are everywhere

In the past two decades technology has been transfer from developed countries between USA to developing country like Nepal as well as a result most of the citizens of Nepal have been using the computer these days we use computer because of its influence in professional endavende in daily life with the event of computer all science accounting financial cultural 8 historical medical engineering and other disciplines are required to change with the base of computer or computing environment no discipline self survive for long time without their studies through computer used to say mathematics is a good of science in the same context computing has been recognised as brain for all kinds of operational area
our past generation was referred as illiterate as they were not capable of writing a letter to their children and their deers in addition to this these days the people would be treated as electric because of in capability to send message to email nowadays computing environment is really very interactive and has also reduced stanza lot now the world has increases with the computer users.

Concept of computer

the development of computer is not a one days invention in fact it's begin with the civilization and computing instruction on device the word computer comes from Latin word computar compute in English which means to calculate the word calculate means to find out the result of some operation on a merry and non numeric values for computer is normally considered to be a calculating device at high speed moreover computer is defined in the Oxford dictionary as an automatic electronic apparatus of making calculation or controlling operation theatre expressible in numerical or logical Term
Some other definition
a computer can be defined as a multi proposed programmable electronic data processing device that is capable of accepting data processing IIT and producing of refined data as output at enormous speed
compare may be defined as machine that can solve problem by shifting data performing 14 operation and representing results of those operation in sequential struction so so sweet of sequence instructions which causes of computer program to perform particular operation is called a program
A computer cancan defined as a programmable digital automatic machine which takes input from the user process it and gives output in the desired form to the user and store it if necessary
computer is an electronic device which can perform computation as well as logical action at enormous speed
Characteristics (features or compability) of computer

1.SPEED

 

The data processing a sweet of electronic come there is very fast because the signals can pass at the speed of electricity which is near to that of speed of light that  2.99 7 X 20^8 m/sec. Thus millions of calculation can be done in a second source is fidaa beyond on the comprehension of the human brain
       the processing speed of a microprocessor is usually measured in millions of instruction for second (MIPS or though put is also used in computer lecture for number of instruction per second).

2.ACCURACY

   

The accuracy of computer is consistently high and every calculation is performed with the same accuracy that is almost 100% accurate result are always same as per design the degree of accuracy of a particular computer depends upon its design.
 According software needs to be designed the folly and proper check and controller necessary in the program in data errors can occur in the in a computer system due to inaccurate data instruction feed by  human or end users.
