Computer Devices And Their Inventors
Computer Knowledge section holds its importance and is considered as the most accessible section for candidates who put little efforts on this section from the first day of their preparation. The main aim of computer awareness section is to test the candidate’s basic computer knowledge skills. Aspirants should prepare with all the concepts which gives basic information about computers. From last 3 to 4 years this part is introduced into the banking exams as computers are playing a prominent role in banking industry.
Candidates are covered with basic concepts like bank computerization essentials, computer introduction, classification of computer, development field of computer, topics about super computers, history of computers, software handshaking, windows, office, early electronic computer generation, e-world, general computer terms, networking, payment system, electronic banking, internet banking, information technology, security of the internet. According to our observation candidates should cover all these topics carefully to score high in bank exams.
To help we are providing all the possible information and computer knowledge materials for candidates. In this article we are providing information about computer devices and their inventors to help the candidates.
