Parts of a Computer

 

Parts of a computer:



8 essential parts:
1. Case, Monitor, Keyboard, Mouse - peripherals  


case: box around all the parts

- easy to open up
-large enough to fit everything into it
- large exhaust fans
- compatible with motherboard


Monitor:

consider size(23", 27", larger?) 
resolution (how many pixels it displays - how sharp the image is)
one monitor or two?  





Keyboard:




Mouse:




Considerations:
Ergonomics!  Make sure you are comfortable using it.
Scroll options
Wired vs. wireless



2. Power Supply
Provides power to motherboard and expansion slots.
 - adequate wattage

- modular plugs - manage cables
Fan - heat management.  

 




3. Motherboard:






Ties all the parts of the computer together
 - ties together processor, memory, power supply, video cards, keyboard, mouse, sound, monitor etc.







-AGP - Accelerated Graphics Port channel for attaching a video card

-RAM - Random Access memory - temporary data storage that can be accessed in any random order.  Temporary - is gone if you shut the computer down (if you did not save your work, and the computer shuts down, it will be gone because it was only in RAM.)

ROM - read-only memory. Permanently stored data. ROM stores your computer's configuration is and is necessary to boot the operating system.

-PCI - Peripheral Component Interconnect – attach hardware devices like network cards, sound cards, modems etc.

-ISA Industry Standard Architecture IBM computer bus   

Bios Basic Input/Output system, or basic integrated operating system, performs basic functions like booting and keyboard control.  

CMOS battery – stores the system time and CMOS BIOS settings when computer is off (Complementary metal oxide semiconductor)
- EIDE - Enhanced integrated drive electronics, or ATA storage device connector, like hard disks & floppy drives

-CPU - Central Processing Unit




PCI express - 
Peripheral Component Interconnect Express serial expansion bus
SATA - Serial ATA (Advanced Technology Attachment) bus interface that connects bus adapters to storage devices like hard disk drives and optical drives.

ATX - default form factor, full-size ATX board is 12 × 9.6 in (305 × 244 mm).

DDR - double data rate RAM - high transfer rates

HDMI (High-Definition Multimedia Interface) audio/video interface for transferring uncompressed video data



4. CPU - central processing unit, hardware in computer that performs input/output operations, decodes, and performs calculations.

Multiprocessing - more than one CPU
Multi-core processors - multiple CPU's on single chip

located next to big fan, most expensive part of computer

  • Intel - LGA (land grid array) socket, no pins, just gold contacts
  • AMD - pins 

 

  • Fan - important to keep CPU from overheating!!


5. Memory


DIMM - dual in-line memory module,  series of dynamic random-access memory integrated circuits.




RAM - Random Access Memory
temporary memory that only works when the computer is on, then it is flushed out.

6. Video Card
DVI - Digital Visual Interface





Discrete video card - separate from what you get on motherboard

PCI  (Express) -  Peripheral Component Interconnect, serial computer expansion bus

  • serial communication sends data one bit at a time, sequentially, over a communication channel or computer bus.

  • parallel communication,  several bits are sent as a whole, on a link with several parallel channels.
 
7. Storage (HDD/SSD) - AKA hard drive
Permanent memory storage (does not disappear when computer is turned off, like RAM/DIMM)
Mechanical hard drive.  Two different types:


  • HDD - hard disk drive -uses rapidly rotating "hard" disks coated with magnetic material.  Magnetic heads arranged on a moving actuator arm read and write data to the surfaces. Data is read in a random-access manner, meaning individual blocks of data can be stored or retrieved in any order rather than sequentially.  



  • SSD - solid-state drive/solid-state disk
 - no moving parts, no actual "disk" of any kind,
- no motors to "drive" the disks, -
- data storage device using integrated circuit assemblies as memory to permanently store data
- fast and quiet


    8. Optical Drive
    reads and writes to CD's, DVD, and Blue Ray disks.

    CD - "compact disk", originally created for music, expanded for use with storing data.
    • CD-ROM: Read-Only Memory
    • CD-R - "Recordable" is a Write Once Read Many (WORM) optical medium
    • CD-RW "re-written"



    DVD "Digital Video Disc" or "Digital Versatile Disc", originally for videos, expanded for use with music and other data.  
     
    Blue Ray - can store video and audio with greater definition


    I/O  (Input Output)
    keyboard, mouse, USB, Printer, Monitor etc.

    BIOS - Basic input output system for loading

    UEFI - Unified Extensible Firmware Interface
    replace BIOS in newer computers, interface between OS and firmware.

    OS - Operating System - software that manages hardware resources - links programs with hardware. (UNIX, Solaris, Linux, Mac OS X, Microsoft Windows)

    Program - instructions to perform a task.

    Measurements:


    ¨Bit (b) – Binary Digit, value of 0 or 1
    ¨Byte (B) – 8 bits
    ¨Kilobyte (KB) – 1024 bytes (210 bytes)
    ¨Megabyte (MB) – 1024 * 1024 bytes (220 bytes)
    ¨Gigabyte (GB) – 1024 * 1024 * 1024 bytes (230 bytes)
    ¨Terabyte (TB) – 1024 * 1024 * 1024 * 1024 bytes (240 bytes)

    **Build a Computer:**

     



    Computer Engineering Lab



    The purpose of this lab is to familiarize you with the major components of a personal computer.  I want you to “build” a personal computer by selecting components you find on the web.  List the details for each component as described below.  Make sure that the components you choose work together and that the power supply you choose is adequate for your power budget.  For this lab, assume heat issues have been mitigated with appropriate cooling techniques.
