7 MAY----- STUDY MATERIAL--COMPUTER APTITUDE FOR WRITTEN EXAM--- SBI PO / SBI JUNIOR ASSOCIATES (CLERK)

Dear Candidate,

Purpose : To prepare written exam of SBI JUNIOR ASSOCIATES (CLERK)/  SBI PO

Now there are more than 100 post on this subject in this link, you can view all previous posts also .

Computer terminologies and abbreviations are frequently asked in Bank PO and other bank exams .

  • mainframe - powerful computer used mainly by large organizations for bulk data processing such as census, industry and consumer statistics, enterprise resource planning, and financial transaction processing.
  • motherboard - the central printed circuit board (PCB) in many modern computers which holds many of the crucial components of the system, while providing connectors for other peripherals.
  • memory - devices that are used to store data or programs on a temporary or permanent basis for use in an electronic digital computer.
  • monitor - an electronic visual display for computers.
  • mouse - a pointing device that functions by detecting two-dimensional motion relative to its supporting surface.
  • Mini-VGA - small connectors used on some laptops and other systems in place of the standard VGA connector.
  • Microcode - a layer of hardware-level instructions involved in the implementation of higher level machine code instructions in many computers and other processors.
  • Mask ROM - a type of read-only memory (ROM) whose contents are programmed by the integrated circuit manufacturer
  • optical disc drive - a disk drive that uses laser light or electromagnetic waves near the light spectrum as part of the process of reading or writing data to or from optical discs.
  • Operating system - the set of software that manages computer hardware resources and provide common services for computer programs.
  • Operation code - Several bits in a computer program instruction that specify which operation to perform.
  • pen drive - another name for a USB flash drive.
  • peripheral - a device attached to a computer but not part of it.
  • personal computer - any general-purpose computer whose size, capabilities, and original sales price make it useful for individuals, and which is intended to be operated directly by an end user, with no intervening computer operator.
  • printer - a peripheral which produces a text or graphics of documents stored in electronic form, usually on physical print media such as paper or transparencies.
  • PSU (power supply unit) - A unit of the computer that converts mains AC to low-voltage regulated DC for the power of all the computer components.
  • PROM (Programmable Read-Only Memory) - a type of non-volatile memory chip that may be programmed after the device is constructed.
  • PCIe (Peripheral Component Interconnect Express) - a computer expansion bus standard designed to replace the older PCI, PCI-X, and AGP bus standards.
  • PCI-X (PCI-eXtended) - a computer bus and expansion card standard that enhances the 32-bit PCI Local Bus for higher bandwidth demanded by servers.
  • RAID (Redundant Array of Independent Disks) - data storage schemes that can divide and replicate data across multiple hard disk drives in order to increase reliability, allow faster access, or both.
  • RAM (random-access memory) - any form of computer data storage that allow stored data to be accessed in any order (i.e., at random).
  • ROM (Read Only Memory) - a type of memory chip that retains its data when its power supply is switched off.
  • server - a computer which may be used to provide services to clients.
  • software - computer programs and other kinds of information read and written by computers.
  • SIMM (single in-line memory module) - a type of memory module containing random access memory used in computers from the early 1980s to the late 1990s.
  • Solid-state drive (or solid-state disk or electronic disk) - a data storage device that uses integrated circuit assemblies as memory to store data persistently.
  • SRAM (Static random-access memory) - a type of semiconductor memory that uses bistable latching circuitry to store each bit. The term static differentiates it from dynamic RAM (DRAM) which must be periodically refreshed.
  • SDRAM (Synchronous dynamic random access memory) - dynamic random access memory that is synchronized with the system bus.
  • tape drive - a peripheral device that allows only sequential access, typically using magnetic tape.
  • terminal - an electronic or electromechanical hardware device that is used for entering data into, and displaying data from, a computer or a computing system.
  • touchpad or trackpad - a pointing device consisting of specialized surface that can translate the motion and position of a user's fingers or a stylus to a relative position on a screen.
  • USB (Universal Serial Bus) - a specification to establish communication between devices and a host controller (usually a personal computers).
  • USB flash drive - a flash memory device integrated with a USB interface. USB flash drives are typically removable and rewritable.
  • VGA (Video Graphics Array) - the last graphical standard introduced by IBM to which the majority of PC clone manufacturers conformed.
  • Volatile memory - memory that requires power to maintain the stored information.
  • Virus - a computer program that can replicate itself and spread from one computer to another. The term "virus" is also commonly, but erroneously, used to refer to other types of malware, including but not limited to adware and spyware programs that do not have a reproductive ability.
  • Webcam - A webcam is a video camera that feeds its images in real time to a computer or computer network, often via USB, Ethernet, or Wi-Fi.
