Limitations and Brief History of Computers: Part 1

Spread the love
There are many such tangible and intangible characteristics of a computer, which help the users to do their works in the best possible and hassle free manner. Thus, with above characteristics computers do have a strong point to enter every sphere of life, but as all have some or the other instructions, as nothing in this universe is perfect, computers do have some limitations, which still do not over shadow the advantages of computers.

Limitations of Computers in Computer Studies

Though, the computers have innumerable advantages, but they so come with some limitations. These limitations are few, which are overshadowed by the advantages they come with. Let us look into some of the major limitations of the computers:
a)      Computer does not work on itself, it requires set of instructions to be provided for, and else computer (hardware) is a waste.
b)      Computers are not intelligent, they have to be instructed about each and every step which they have to perform, and i.e. every link to be performed by them should be given in details.
c)       Computers cannot take decisions on its own; one has to program the computer to take in action if some conditions prevail.
d)      Computers, unlike humans cannot learn by experience.

Brief History of Computers

Ever since the man thought of counting, be developed the concept of computing. His initial approach to accounting and data computations and their recording was with help of sticks, pebbles or lines on walls of caves. Then he moved towards counting using ten fingers of his hands, which probably id the basis of present decimal system. This quest of man for better computing and hassle free process and device made him to work towards a device which could do all that he wanted in computing. There has been a series of devices, which were there before this revolutionary device could be invented. The devices like Abacus, Mechanical Calculator, etc can be taken as predecessors for the molders day Computer.
Man gradually develop mathematical ideas and went on inventing better tools for commutations and calculations. The earliest computing device, which was used by Egyptians as early as 450 B.C., is ABACUS. The Chinese version of ABACUS was a bead on wires counting frame, which is still much is use is south East Asia, China and Japan. The first desk top calculator machine, which is capable to perform various arithmetic operations, was developed as early as 1642, which was pioneered by French Scientist Blaise Pascal (1623-1662). This calculating machine mainly consisted of gears and wheels for calculations and this machine could perform only two basic operations i.e. addition and subtraction.
A German mathematician Gottfried Leibnitz on improving this machine i.e. Pascal’s calculator for performing four basic air thematic operations i.e. addition, subtraction, multiplication and division. He suggested the use of Binary system instead of decimal system for the mechanical calculator. The word “Computer” comes from the word “compute” which means to calculate. Thus computer is normally considered as a device which performs air thematic operations at enormous speeds, but it is even more efficiency used in other areas which are not exactly related to air thematic calculations.
