Internal components - Technical

  1. 1. Processors  CPU is a short name for Central Processing Unit, (CPU) it’s a brain of the computer. The CPU will likely be the larger of the chips on the mainboard inside your PC  The are only CPU measured in 64-bit and 32-bit.  There are many different types of CPU speed, CPU does matter how much speed that your laptop or desktop need.  CPU compatibility with your laptop or desktop motherboard.
  2. 2.  ROM stand for Read-OnlyMemory memory, is a class of storage medium used in computers and other electronic devices. Data stored in ROM cannot be modified, or can be modified only slowly or with difficult, so it is mainly used to distribute firmware.  RAM stand for Random Access Memory, RAM is a form of computer data storage, it takes the form of integrated circuits that allow stored data to be accessed in any order with a worst case performance of constant time.
  3. 3. Memory  EPROM stand for erasable programmable(part 2) read only memory, is a type of memory chip that retains its data when its power supply is switched off.  Flash memory is a non- volatile computer storage chip that can be electrically erased and reprogrammed. It was developed from EEPROM and must be erased in fairly large blocks before these can be rewritten with new data.
  4. 4.  Video card is an expansion card which generates output images to a display, video hardware isAdapter Card often integrated into the motherboard, however all modern motherboards provide expansion ports to which a video card can be attached.  Sound card is an internal computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs.  Network card is a computer hardware component that connects a computer to a computer network. Whereas network interface controllers were commonly implemented on expansion cards that plug into a computer bus.
  5. 5.  SATA stand for Serial Advanced TechnologyStorage Devices Attachment) is a computer bus interface for connecting host bus adapters to mass storage devices such as hard disk drives and optical drives.  PATA stand for Parallel ATA , originally AT Attachment, is an interface standard for the connection of storage devices such as hard disks, solid-state drives, floppy drives, and optical disc drives in computers.
  6. 6.  SCSI stand for Small Computer System Interface and it a set ofStorage Devices standards for physically connecting and transferring data (part 2) between computers and peripheral devices. The SCSI standards define commands, protocols, and electrical and optical interfaces.  Solid state is a data storage device that uses solid-state memory to store persistent data with the intention of providing access in the same manner of a traditional block i/o hard disk drive. SSDs are distinguished from traditional magnetic disks such as hard disk drives (HDDs) or floppy disk, which are electromechanical devices containing spinning disks and movable read/write heads.
  7. 7. Input and  Microphones is an acoustic-to-electric Output Devices transducer or sensor (INPUTS) that converts soundTouch screen is an electronic into an electrical signalvisual display that can detect thepresence and location of a touch  Keyboard is awithin the display area. typewriter-styleGames controllers is a device keyboard, which usesused with games orentertainment systems to an arrangement ofprovide input to a video game, buttons or keys, to acttypically to control an object or as mechanical leverscharacter in the game. Acontroller is usually connected to or electronic switches.a game console or computer bymeans of a wire or cord, althoughwireless controllers are alsowidespread.
  8. 8. Inputs and  Printer is a peripheral which produces a text orOutputs Devices graphics of documents stored in electronic (OUTPUTS) form, usually on physicalMonitor is an electronic visual print media such asdisplay for computers. The paper or transparencies.monitor comprises the displaydevice, circuitry, and an Many printers areenclosures. primarily used as local peripherals, and areSpeakers is an electro acoustic attached by a printertransducer that produces soundin response to an electrical audio cable or, in most newsignal output. printers, a USB cable to a computer which serves as a document source.
