Her work helped a great deal in the advancement of computer system. She has given the concept that ‘computers can be programmed’. Lovelace was an English mathematician, who researched on Babbage’s work. In 1822, he developed a machine capable to calculate the successive difference of expression and prepared a table which helped him in his calculations. Charles Babbageīabbage was an English Polymath, Mathematician, Mechanical Engineer, Philosopher, and Inventor. Pascal was a French mathematician who invented a machine based on gear wheels, which helped greatly in calculation. Napier named sticks ‘bones,’ as they were made up of bones. Napier was a Scottish mathematician who invented logarithms.įurther, Napier also invented a computing device, which consisted of sticks with numbers imprinted on them. Let us now read about the innovators who contributed immensely in the development of a computer system. The present Computer System has evolved after centuries of efforts from different intellectuals who contributed their works during different periods of time.Ībacus is (most likely) considered as the earlier counting device. Vast memory − A computer system can have a wide range of memory which can recall the desired data at any point of time. Reliability − As a computer system always gives accurate result therefore, its reliability is very high. Versatility − A computer system is capable of performing a wide range of tasks.ĭiligence − A computer neither get tired nor lose concentration. The storage capacity of a computer system is normally expressed in terms of Kilobytes (KB), Megabytes (MB), Gigabytes (GB), or Terabytes (TB).Īccuracy − The accuracy of a computer system is very high.
Storage − A computer system can store enormous quantity of data in different format. Speed − Depending upon the power of the computer, it can perform, it can take Millions of instructions per second. Major Functions of Computer Systemįollowing are the core functions of a computer system −Ī computer accepts the command and/or data as input given by the user.Ī computer follows the instructions and stores the data given by the user.Ī computer processes the data as per the instructions given by the user.Ī computer gives the desirable results in the form of output.įollowing are the salient features of a Computer System −Īutomation − The operating system of a computer system is automatic, as no human intervention is required simply you need to give the command and then it will do the work automatically. However, over a period of time, this device technically advanced at present, it can perform a wide range of desirable works apart from data processing. The term “computer” is derived from a Latin term “compute,” which means ‘to calculate.’ Initially, the computer system had been designed to calculate it was intended to be a computing device.
