Education is a continuous process.In the new education system , more emphasis is put on the student and his learning abilities.The learning process has been given its due importance as compared to the teaching process.Hence, it is the aim of all the teaching aids like diagrams,charts,video clips,slides,etc. and methods to make the learning process simple,effective and enjoyable .In fact,rectification of all the queries  and difficulties of a student and motivating him to acquire higher and higher knowledge is the true aim of an education system. Computers programs can also be developed to test a particular skill and knowledge of a student . Nowadays , some of the examinations are conducted on the computer itself and the results are declared within minutes. Hence the traditional evaluation methods can be replaced by automated evaluation methods. Moreover,depending on the results of the evaluation,computers can also suggest the methods to improve the skill and knowledge of the st...
