Characteristics of a Computer System in Full Deeply Knowledge Online

What is computer? The basic question is the bottle neck, as it is quite difficult to define the term computer, so precisely. We can define computer as “a device that processes given data to derive the required and useful information”.

During the processing the computer has to perform various functions

a)      Accepting instructions from the user.
b)      Accepting data from the user.
c)       Performing various air thematic and logical operations as per instructions given.
d)      Presenting the information or output to the user.

Characteristics of a Computer System

Computers are becoming popular and indispensable product, day by day because of their characteristics, which makes them the most popular as well as indispensable. The characteristics which make the computer indispensable are:
Fastness: the speed at which the computer operates is very high; it is really difficult to match the speed. It is usually measured in MIPS (Million Instructions per Second). Computer is able to process the data and give the output in fractions of seconds such that required information is given to the user on time enabling the user to take right decisions on right time. A powerful computer is cap-able to executing about 3 million calculations per second. Thus, we can see that fastness of a computer is a characteristic which gives it the power to manage the extreme data demands.
Accuracy: One can actually vouch by the accuracy of the computer. In spite of its high speed of processing, errors seldom occur, as computer’s accuracy is consistently high enough which avoids any errors. It at all there are errors, they are due to errors in instructions given by the programmer, inaccurate and inconsistent data or defective programs as well defective systems designs. If these holes of defects or poor programming are avoided, then there would to almost no incidence of errors. This makes the computer a very sought after product, which can be relied on for maintaining and working for a business.
Reliable: One has to always have the component of reliability for second. The output generated by the computer is very reliable, but it is reliable only when the data which is passing as input to the computer and the program, which gives instructions, are correct and reliable. Thus, one can conclude that the computer is very much reliable, it only the input which makes the difference. Inconsistent, incorrect and unreliable programs and data make the computer erroneous and unreliable. I.e. if you want the computer to be reliable the input should be reliable. The popular phrase “Garbage in-Garbage out” i.e. GIGO represents the reliability consistent of the computer.
Large Storage Capacity: The basic problem of pre-computer era was the storage of voluminous data which required large amount of paper and storage space, such that even the storage and retrieval of data becomes a herculean task. The computer has solved this problem by giving a provision to store large volumes of data and help the retrieval of data an easy task. Though in the initial era there were some memory related issues, but with the evolution of technology. It has been solved and now we have the technology, which stores voluminous data in very small devices, easy to handle and work with.
