Limitations of Computers
Benefits and Limitations of Computers
The fact that computers have made their impact of almost all aspects of life in today's world can hardly be questioned. The question that you may ask here is how do you benefit from using a computer.
A computer provides three basic benefits:
- Speed
- Accuracy (Accurate work)
- Diligence (care full hard work or toady effort)
Computers work at very high speeds and are much faster than humans. The human equivalent of an average computer would be one million mathematicians working 24 hours a day. A computer rarely makes mistakes. In fact, most computer errors are cusec by human facilities. Unlike human, computers simply do not get bother or tired. The monotony of repetitive works does not affect computer. Unanticipated situation arises, computer will either produce erroneous results or abandon the task altogether. They do not have the potential to work out and alternative solution.
Computer of a PC system -the Hardware.
Now that you know the benefits and limitations of computer. let us move on to identifying each component of the personal computer with which you will be working during the course. The until that resembles a TV screen is called the Monitor, or more commonly VDU, short form for visual Display Unit.
The component that closely resembles a typewriter is called the Keyboard. The box like structure that houses the necessary components to run the system is called the system unit.
The Printer, as the name suggests, is used to print the results of any operation.
The tiny device connected to the system unit through a cord, resembling a tail is called a Mouse. Moving the Mouse produces a corresponding movement of an arrowhead on the VDU. These devices are collectively known as the Hardware. Thus hardware comprises of all the physical components of a PC system.
