Introduction to computer
The d word computer is derived from the word computer, which means calculation. Then In colloquial language it is considered as a calculating device that can do arithmetic and lo1 Types of computer
gical operations with speed, but today and
logical with compute is not limited to calculation today it is used for
Changes into information and presents the output resulted it accepts stores and manipulates data according to our need.
1 Types of computer
Characteristics of computer and likely to be defined or tell the capability of compute .
Speed..
Computers. Can carry out instructions in less than a millionth of a second .
As you know computers can we our very fast., 1 Types of computer In takes only few second for calculations that we take hours to instructions and even more per second.
Accuracy..
Computers can do the do the calculations without errors and d very accurately.
2 computer full form
The de grief accuracy of computer is very high and every calculations is performed with the same accuracy. The errors in computer are due to human and l inaccurate data.
Diligence;
Computers are capable of performing any task given to them repetitively.
2 computer full form
A computer is free from tiredness, lack of concentration, weakness, etc. It can work for hours without creating any error. If millions of calculations are to be performed
Due to this capability it of very power res human beinginro8utiene type of work
