6 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 abbeviations are frequently asked in Bank PO and other bank exams . :
  • accumulator - a register in a CPU in which intermediate arithmetic and logic results are stored.
  • address - the unique number that specifies a memory location.
  • ATX (Advanced Technology extended) - a motherboard form factor specification developed by Intel in 1995 to improve on previous DE factor standards like the AT form factor.
  • AT - the dimensions and layout (form factor) of the motherboard for the IBM AT.
  • AGP (Accelerated Graphics Port) - a high-speed point-to-point channel for attaching a video card to a computer's motherboard, primarily to assist in the acceleration of 3D computer graphics.
  • bus - a subsystem that transfers data between computer components inside a computer or between computers.
  • Blu-ray Disc - a optical disc storage medium designed to supersede the DVD format.
  • BASIC (Beginner's All-purpose Symbolic Instruction Code) - a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use.
  • cache - a fast memory that transparently improves the performance of a larger, but slower memory or storage device.
  • CD-R (Compact Disc-Recordable) - a variation of the optical compact disc which may be written to once.
  • CD-RW (Compact Disc-ReWritable) - a variation of the optical compact disc which may be written to many times.
  • CD-ROM (Compact Disc Read-Only Memory) - a pre-pressed optical compact disc which contains data or music playback.
  • chip (or integrated circuit) - a miniaturized electronic circuit that has been manufactured in the surface of a thin substrate of semiconductor material.
  • control store - the memory that stores the microcode of a CPU.
  • core - the portion of a CPU which actually performs arithemetic and logical operations. A CPU may have multiple cores (e.g. "a quad-core processor").
  • core memory - in modern usage, a synonym for main memory, dating back from the pre-semiconductor-chip times when the dominant main memory technology wasmagnetic core memory.
  • CPU (Central processing unit) - the portion of a computer system that executes the instructions of a computer program.
  • Conventional PCI (Conventional Peripheral Component Interconnect) - a computer bus for attaching hardware devices in a computer.
  • Computer case (or computer chassis, cabinet, box, tower, enclosure, housing, system unit or simply case) - the enclosure that contains most of the components of a computer (usually excluding the display, keyboard and mouse).
  • Computer form factor - the name used to denote the dimensions, power supply type, location of mounting holes, number of ports on the back panel, etc.
  • Chipset (or chip set) - a group of integrated circuits, or chips, that are designed to work together. They are usually marketed as a single product.
  • Channel I/O - a generic term that refers to a high-performance input/output (I/O) architecture that is implemented in various forms on a number of computer architectures, especially on mainframe computers..
  • DVD (Digital Video Disc or Digital Versatile Disc) - an optical compact disc - of the same dimensions as compact discs (CDs), but store more than six times as much data.
  • DASD (Direct Access Storage Device) - mainframe terminology introduced by IBM denoting secondary storage with random access, typically (arrays of) hard disk drives.
  • DIMM (dual in-line memory module) - a series of dynamic random-access memory integrated circuits. These modules are mounted on a printed circuit board and designed for use in personal computers, workstations and servers.
  • DisplayPort - DisplayPort is a digital display interface developed by the Video Electronics Standards Association (VESA). The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to transmit audio, USB, and other forms of data.
  • DVI - Digital Visual Interface (DVI) is a video display interface developed by the Digital Display Working Group (DDWG). The digital interface is used to connect a video source to a display device, such as a computer monitor.
  • DRAM (Dynamic random-access memory) - a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit and which must be periodically refreshed to retain the stored data.
  • Firewall - A hardware device or software to protect a computer from viruses, malware, trojans etc.
  • firmware - fixed programs and data that internally control various electronic devices.
  • floppy disk - a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium encased in a square or rectangular plastic shell.
  • floppy disk drive - a device for reading floppy disks.
  • Flash Memory - a type of non volatile computer storage chip that can be electrically erased and reprogrammed.
  • hard drive - a non-volatile storage device that stores data on rapidly rotating rigid (i.e. hard) platters with magnetic surfaces.
  • hardware - the physical components of a computer.
  • HDMI (High-Definition Multimedia Interface) - a compact interface for transferring encrypted uncompressed digital audio and video data to a device such as a computer monitor, video projector or digital television.
  • input device - any peripheral equipment used to provide data and control signals to an information processing system.
  • input/output - the communication between an information processing system (such as a computer), and the outside world.
  • IOPS (Input/Output Operations Per Second, pronounced eye-ops) - a common performance measurement used to benchmark computer storage devices like hard disk drives.
  • instruction - a group of several bits in a computer program that contains an operation code and usually one or more memory addresses.
  • keyboard - an input device, partially modeled after the typewriter keyboard, which uses an arrangement of buttons or keys, to act as mechanical levers or electronic switches.
