TASK1
TASK1: Identification of the peripherals of a computer - Prepare a report containing the block diagram of the computer along with the configuration of each component and its functionality. Describe about various I/O Devices and its usage.
Computer:A computer is a machine that accepts data as input, processes that data using programs, and outputs the processed data as information. Many computers can store and retrieve information using hard drives. Computers can be connected together to form networks, allowing connected computers to communicate with each other.
Software Requirement: No Software Required.
Hardware Requirement: Desired Configuration for the above task is
System unit
CPU
Mother Board
FDD
CDROM Drive
HDD
Ethernet Card
Monitor, Keyboard, Mouse & Speakers
Safety Precautions:
1. Beware of electro static discharge (ESO)
2. Build computer on a hard surface, away from concepts.
3. Wear shoes and the short sleeved cotton wear.
4. Use Phillips, head screw driver.
5. Keep the components away from moisture.
6. Avoid using pressure while installing.
BLOCK DIAGRAM OF COMPUTER
Peripherals of a computer:
Cabinet:
It is used to install all hardware devices like(mother board, SMPS, HDD, CD Rom, FDD)
It has Start, Restart Button, Led’s, Audio and USB Connecters are available at front side.
Monitor:
Monitor of a computer is like a television screen.
It displays text characters and graphics in colours or in shades of grey.
The monitor is also called as screen or display or CRT (cathode ray tube). In the monitor the screen will be displayed in pixels format
Key Board:
Keyboard is like a type writer, which contains keys to feed the data or information into the computer
Keyboards are available in two modules. These are
Standard keyboard with 83-88keys
Enhanced key board with 104 keys or above
Mouse:
Every mouse has one primary button (left button) and one secondary button(right button).
The primary button is used to carry out most tasks, where as secondary button is used in special cases you can select commands and options
Printer:
A device that prints images (numbers, alphabets, graphs etc…) on paper is known as Printer.
We have different types of printers to take printouts. These are as follows:
Dot matrix printer ii. Ink jet printer
Speakers:
Speakers make your system much more delightful to seen you while you are working on computer
Scanner: Scanner used to scan images and text.
8. System board/Motherboard
This is the major part of the PC hardware.
It manages all transactions of data between CPU peripherals.
Which holds the Processor, Random Access Memory and other parts, & has slots for expansion cards.
It is rectangle shape.
Socket478:
It use 478 – PIN MICROPGA package it is used installing CPU .It is square type design.
CPU
The central processing unit contains the heart of any computer, the processor. The processor is fitted on to a Mother Board. The Mother Board contains various components, which support the functioning of a PC.
It is brain of the computer
It is square shape
Ram Slots:
Ram slots are used to install the rams
It is large rectangle shape and each ending has small clips.
There two types ram slots
SD Ram ----------Two Gaps (synchronous DRAM) is a generic name for various kinds of dynamic random access memory (DRAM) that are synchronized with the clock speed that the microprocessor is optimized for. This tends to increase the number of instructions that the processor can perform in a given time.
DDR Ram One Gap(Double Data Rate Synchronous DRAM:A clock is used to read data from
a DRAM. DDR memory reads data on both the rising and falling edge of the clock, achieving a faster data rate.)
North Bridge:
It is also called as controller
It is nearby socket 478
It placed middle of the mother board and
It converts electronic signals to binary values and binary values to electronic signals
South Bridge:
It is controls major components mother board and it back bone of the input output devices.
It is communicates PCI slots, IDE-1, IDE-2, floppy connecter, BIOS chip.
It nearby CMOS battery
CMOS Battery:
Computer is using a coin shape battery
It generates the clock signal and it manage system continues time.
Primary & Secondary (IDE-1&IDE-2):
It is also called as IDE-1, IDE-2.
It used to connecting Hard Disk Drive, CD ROM, DVD ROM.
Input& Output ports:
IO ports are used to connecting IO device such as keyboards, mouse, monitor, printer, scanner, speakers etc...
AGP Slot & AGP Card:
AGP Slot is used install the AGP card.
AGP back view same as VGA port (15-femalepins) and used to connecting the monitor’s. This slot is above PCI slots and its colour is Black or Brown
CI Slots & PCI (Expansion)Cards:
PCI slots are used to install the PCI cards such as
LAN(Ethernet)Card---Back view Ethernet port
Sound Card-Back view Audio pin connectors)
TV Tuner(Internal) Card-Dish Pin connecter
PCI Slots are white or yellow colour
PCI Card has Single gap only
BIOS Chip:
BIOS controls how the operating system and hardware work together
BIOS identification is BIOS name is available on chip or motherboard
ATX Power connecter:
ATX power connecter is used to connect ATX power plug(This is from SMPS)
It is white colour and it has ATX Name is available on Mother Board
ATX Power connecter has 20/24 pins available.
Typical ATX 1.3 power supply. From left to right ,the connectors are 20-pin mother board,4-pin"P4connector", fan RPM monitor (note the lack of a power wire), SATA power connector (black),"Mole x connector" and floppy connector.
Floppy connecter:
Floppy connecter is used to connect Floppy Disk Drive.
This is beside of ATX power connecter and Name FDD is available on the mother board.
Bus Cables or Data cables:
A Bus is a collection device cables are two types
IDE cable: it used to connect HDD,CD ROM, DVD ROM
FDD cable: it used to connect FDD(braking or manufacture defecting) of wires through which data is transmitted from one device to another
Hard Disk Drive:
The hard disk drive is the main, and usually largest, data storage device in a computer
The operating system, software titles and most other files are stored in the hard disk drive
Identifications is the panel name is Hard Disk dive
CD ROM Drive & CD-Writer:
CD-Rom (Compact Disk Read only Memory) Drive is a device that reads the information from Compact Disks (CD).
CD-Writer is used to write the data into Compact Disks.
Identification is the panel name is CD Writer
Floppy Disk Drive:
The floppy disk drive is used to read the information stored in floppy disks.
Floppy disks also called as a diskette.
Identification is smaller than CD Writer.
SMPS:
SMPS is used to supply the power to Mother Board HDD,CD ROM,FDD
In SMPS holds a transformer , voltage control and fan
Identification is the rectangular box shape and panel name is switching mode power supply.
