The characteristics of computers are:
1. Speed: Computers are fast in doing calculations. The speed of the computer is measured in terms of million instruction per second (MIPS).
2. Storage Capacity: Computers come with large amount of memory. They can hold lot of data. Computers can show a particular piece of information from large amount of data in a short time.
3. Diligence: After doing work for sometime, humans become tired but computers do not become tired. They work continuously. In fact, some computers which control telephone exchanges are never stopped. This is called diligence.
4. Accuracy: The results that the computers produce are accurate provided data and programs are reliable.
5. Versatality: We can use computer to perform completely different type of work at the same time.
6. Reliability: Computers work for many years without any problem. Few computers in the world are never switched off.
