1. Speed
Speed is the main trait of a PC. The
computer can perform billions of calculations in fraction of a second. For
example; if a student’s is asked to calculate the following product.
8743963
x 68935
The student will take few minutes to solve it, but a computer can solve
millions of such problems in less than a second.
2. Accuracy
Computer is almost 100% accurate and it never makes mistakes. In the above example, there is a chance that the students can make errors while solving it but a computer never does so. Computer gives wrong results only when defective data or instructions are given.
3. Diligence
Other than
being quick, a PC can get things done again and again. It never gets tired or
bored. If we have to write a letter 100 times we will get tried. A computer can
write the letter even a million times but never gets tired or bored.
4. Storage
PCs have huge
capacity limit. A large building is required to store thousands of books. However,
a PC can without much of a stretch store a large number of books in its memory.
5. Versatility
Versatility is the key benefit of using computers. A user can perform variety of tasks with a computer like drawing pictures, writing stories, watching movies, playing games.
Components of a Computer
The computer has a variety of functions. Equipment
and Software are the principle parts of a PC.
1. Hardware
Hardware refers to all parts
of a computer that we see and touch. This includes input and output devices and
system unit.
2. Software
