Computer Knowledge

Every field today is automated or computerized; no work can be completed in an organization without the use of computers or computing process. The computer knowledge is a very crucial section of Common Written Examination in which one can easily score high marks by simple tricks and tips. The questions related to computer knowledge are very basic terms, in which you have to answer the commonly used abbreviations, questions related to functionality of computer systems. The questions in IBPS for computer will be asked for twenty marks. For specialist officers or IT officers in bank, a degree related to computer education is asked.

The banking industry has moved to automation of transactions, processes, and work load. Therefore it is necessary to know about networking, internet handling, office tools and database. The technical aspects of computer knowledge should be known.

Requirement of Computer Literacy Certification:

Since the banks have online transactions and inter-communication processes, it is a necessity to have a certified course experience for knowledge of computers. A candidate should have degree/ course certificate from a recognized institute. The requirements are specified for each of the post accordingly:

P.O. / Management Trainee: A candidate should have valid certificate from a recognized university or have studied Computers as a part of curriculum. The requested certificate should be taken as a part of vocational skill course. There are courses of 3-4 months that presents the requisite knowledge for the IBPS exams.

For SPECIALIST OFFICERS (I.T.): The candidates applying for specialist post (I.T.) a candidate should have studied a four year graduate or a post graduate engineering courses in Computer Science or related fields. A graduate who has passed DOEACC ‘B’ level can also apply for this post in IBPS. No extra requirements are needed for clearing the computer proficiency in CWE.

The syllabus for CWE CLERK-V is very simplified as compared to other official posts recruited through IBPS. Here is a brief idea about what is asked in computer proficiency for CWE.

Antivirus: Antivirus is a software application that is used to protect a computer system against lethal viruses, bugs, and automated scripts that disrupt the normal working of computers. The antiviruses use could protect a system from threats and keep it working safely for longer duration. The different types of antiviruses are built to cater the need of keeping safe computer systems.

Basics of computers: The basic computer knowledge is tested in this section. The topics that form questions are basic parts of computer, use of computers, input and output devices, browsers, applications etc. Which one was the first computer, supercomputers, commercial computers, programming languages, first network, keyboards etc.

Binary Number system: The use of binary number format common to computer systems can be asked from this section. Binary numbers are the basic blocks on which computers work, therefore, basic conversions from one unit to another should also be known to candidates.

Components of computers: The different parts of computers like monitors, Central Processing Unit (CPU), Arithmetical and Logical Unit (ALU), Motherboards, Keyboards, mouse, printer, scanner, memory, and these parts should be distinctly known by students for computer proficiency. Different questions are formed on the basis of components of computers.

Database: The database in computers is an important context to handle data related to different files, formats. The database handles all the queries related to data, create and manipulate different sets if data. The database security, transactions associated to it, commands for assessing it, access grants by database administrator.

Any candidate opting for IBPS, should know simple email usage, types of security related to email and internet, basic email etiquettes. The knowledge about IPv4 and IPv6 networks, role of HTTP, FTP, MIME, POP, TCP/IP protocols, is also must.

Famous founders: The founders of computers and related technologies should be known by one and all. The famous founders of computers, programming languages, famous applications, browser, search engines, emails, wireless and wired networking, mobile phones, keyboard, operating systems, mouse, USB etc. should be on tips of students.

The file formats denotes the type of file and form multiple choice questions. Listing the file formats and remembering them according to the type and usage will be beneficial.

Firewalls: The firewalls are network security systems to protect, monitor, or prevent use of network from unauthorized users. It also monitors the incoming and outgoing traffic based on some specified rules of a system. Firewalls can be implemented on hardware or and acts as a protective server for resources of a computer network.

Generations of computers: The history of computers and technology associated with each of the computer generation is to be studied. The type of technology that initiated formulation of magnetic tapes and discs, batch processing, chips, microprocessor, etc. should be known of. The past and future both depend on each of the technological advancements made over years in computers.

Hardware: The hardware is any physical part of a computer that exists. The knowledge of hardware is necessary for using computers which includes processor, RAM, ROM, disk drives, modems, motherboards, keyboards, mouse, charger, printer etc. The knowledge of computer parts, latest release of processors, graphics card, memory slots, should be properly understood.

Networks: The different types of networks like LAN, WAN, MAN, internet, intranet, etc. their differences, use of a network in a particular situation should be known by candidates preparing for computer literacy paper. The different components of network like switches, routers, gateways, VPN’s, private networks are also important topics. The different topologies used to implement a network like bus, ring, star, hybrid, and mesh must also be studied.

Office Tools: The usage of Microsoft word, Microsoft PowerPoint, spreadsheets, pie charts, should be known. Common short cut keys for using office tools, basic editing and usage skills should be known for attempting questions of computer literacy paper.

Shortcuts: The shortcut keys for accessing systems, browsers, new files, exiting a system, files, media files etc. should be known. What sequences denote which operations, what sequences should be used to execute a task,  shortcut keys for file, running, compiling, etc. comes easily with using computers.

Software: The software is the application part that is used to run an application on computer. This topic involves different operating systems like Windows, Linux, etc., file system hierarchy, indexing in computers, tools for computers, antiviruses, paint, web editors, frameworks, etc. The software used in computers also includes such applications which are used to develop graphics, audios, videos, etc.

Security: The basic security related terminologies, security threats, difference between hackers and crackers, types of security measures, prevention and detection method of security, and principles of security should be studied for understanding computer networks.

A look on previous year papers can be read and found out about the type of questions related to computer awareness.
