What are some advantages of a computer? |
Advantages: 1. Computers can perform calculations much more quickly and accurately than human. 2. Large amounts of data can be stored in a small amount of space. 3. Computers can work continuously and perform repetitive tasks well. Unlike their compute counterparts, computers do not get bored or tired. 4. Computers can stimulate things that would take too long, be too dangerous or simply impossible for humans to attempt. |

What are some of the disadvantages of the computer? |
Disadvantages: 1. The introduction of computers can cause redundancy in the workplace. Employees may lose their jobs if computer can do a job more efficiently and ultimately more cheaply. 2. Computers make it easy for people to misuse information. Computer to make it easy to store large amounts of information about people. In some cases this information can be freely and easily access and use for purposes which it was not originally intended. 3. Downtown happens when a computer based on our data becomes corrupted. Businesses often rely so much on technology that when computers will they have no backup manual system and are temporarily rendered helpless as a result. 4. The introduction of computer system in the work place is expensive. The cost is more only due to the person of the equipment; in some companies the time it takes to train the staff to use the system causes several thousands of dollars of lost productivity. 5. There are health risk associated with excessive or improper use of computers. The glare from the screen can cause eye strain and inadequate support for the wrists when typing can cause carpel-tunnel syndrome. |
