advantages and disadvantages of using computers in an organisations
Answers
Explanation:
1. Speed:
The speed of carrying out the given instruction logically and numerically is incomparable between a computer and human being. Computer can perform and give instructions in less than a millionth of a second. The speed of the computer is specified in terms of Nano seconds and in Pico seconds, whereas human beings require most time to perform these functions.
Therefore, from speed point of view, computer’s functioning is very fast.
2. Accuracy:
Computer calculates very accurately and computer never does mistake although we often hear about the false results of computers. This may be due to the error in data entry or due to poorly designed program. Since, human beings do data entry and programming; hence, the error may make the results false. Otherwise, computer never does mistake. It works on the principle of “Garbage In, Garbage Out”.
3. Versatility:
Previously, the computer was thought as only a calculating machine, but a computer cans also carryout logical operations. Any job can be computerized with the help of appropriate software. Limited sets of instructions are enough to carry out a computer processing.Generally, the use of computer is restricted to typing and storage of information, in most of the business organizations. This may be due to the lack of complete knowledge regarding the use of computer on the part of the user.
4. Reliability:
The information stored in computer is in digital forms. The information can be stored for long time and have long life. If maintained properly, at least data processing and storage components are guaranteed for several years. A user may feel comfortable and be reliable, while using information stored in computer.
Previously, a digital form of information was not accepted in Government departments and the information stored in the floppies was not accepted in the court as evidence. However, after the establishment of Ministry of Information Technology by Government of India, efforts are taken by there Government to provide the legal status to the information stored in the digital form.
5. Storage:
Human brain can store a piece of information to some limitation of numbers and up to some extent of time. When he is asked to reproduce the information after a long period, he may find himself in a difficult situation to recall the information. Human being generally distorts the information.
6. Automatically: A computer performs automatically in user friendly and menu driven program. Electronic equipment like tape recorder, television, and calculator, VCR etc. can be operated with basic knowledge of operation. In the same manner with some basic knowhow technique, a computer can be operated.
7. Compactness:
Now a day, the size of the computer has reduced drastically. The modern computers are laptop and tabletop computers. They do not occupy more space. Moreover, laptop has provided mobility to the computer. Now we can carry computer with us and through remote accessing, we may be in touch with our office.
With the advancement of technology, the benefit of this device has been multiplied. Internet and video conferencing facilities have made it possible for the business executives to control, direct, and monitor the functioning of the office even when they are not present in the office.
8. Repetitiveness:
Computer can be used repetitively to process information. It does not feel mental fatigue as in case of human being. There will be no difference in the speed and accuracy of the information presentation if a computer operates continually even for 1, 2 or any number of days. We can understand the importance of the unique features when company is sending information to its shareholders.Generally, the number of shareholders in any company is very large. To send the information to them manually is very tiresome and time consuming. However, through mail merging, thousands of letters can be prepared and dispatched in a day.
