Hi, friends..
After long time i m met u all in the blog, because from Dec 22 i am working in the Universal Digital Library in the Hardware Team. To day i watched praveen sir Vedio's about inside components of the Computer and Assembling. These are the very interesting.
These are very helpful to beginners.
PC ASSEMBLING
We need to know some thing about the computer hard ware. To trouble shoot the system ourselves.
Some Hardware parts which are used in computer.
Computer contains 4 main functional parts those are
1. Input
2. Output
3. Central Processing Unit (CPU)
4. Memory Storage.
Input: these devices are used to give the input to the system.
Ex: Keyboard, Mouse, etc..
Output: these devices are used to produce the output
Ex: Monitor, Speakers, etc….
Central Processing Unit:
It is also called as brain of the computer. All the processes are executed here.
Most commonly used hardware parts in CPU are:
When I did assembling of my PC I observed some parts those are:
1. Motherboard.
2. Hard Disk.
3. CD-ROM.
4. Floppy Drive.
5. SMPS
Motherboard:
It is an Integrated Printed Circuit Board which contains some electronic devices.
1. PCI slots: In general mother board has 3 PCI (Peripheral Component Interconnection).
In these slots we can install the NIC card and sound card etc……
White color slots in my System.
2. AGP slot: Accelerator Graphics Port is used to connect the AGP card. AGP card is used to improve the speed. AGP is had its own memory and processor so the speed will be increased. The main difference between PCI slot (in Mbps) and AGP slot (in Gbps) is the speed.
Red color slot in my System and is above the PCI slot.
3. System memory (RAM) slot: It is used to put the RAM (Random Access Memory).
This slot is also called as DIM (Dual Input Memory) module.
In the market there are 3 types of RAM
• SD-RAM: Synchronous Dynamic RAM
• DDR SDRAM: Dual Data Rate SDRAM
• RD RAM: Rhombus Dynamic RAM
We can identify them by notches on the RAM.
4. Processor Socket: This is used fix the Processor. It has one liver to fix the processor. When fixing the processor first we need to pull-up the liver and check the missing pins then fix it according to the missing pins then lock the liver.
Processor (My system):
PGA (Pin Grid Array) processor
P-III, 133 MHZ bus speed
25.6 kb cache memory.
5. Heat Sink: This is used to observe the heat generated by the processor. It is also has a fan to cool the Heat Sink. Speed of this fan is approximately 5000 R.P.M
6. IDE Connector (Integrated Device Electronics):
These are used to connect the hard disk, floppy and CD-ROM.
There are two types of IDE connectors
• ATA: Advanced Technology Attachments.
• SATA: Serial ATA.
7. Panel Connectors:
a) Front Panel: There are 4 LED’s to indicate the status of the devices (on/off).
Ex: HDD Led to indicate the Hard disk status.
Power Led to indicate if the C.P.U is on or off status.
b) ATX Connectors (Advanced Technology Extension): It is also called as back panel connector. It is of 2 types
i) Serial Port: COM1 & COM2 (mouse and monitor)
ii) Parallel Port: used to connect the printer.
8. CMOS Battery: It is running with the use of battery. It is also called as Real Time Clock because it is used to run the clock and we can reset the BOIS and CLOCK using this.
9. Power Supply Port: By using this we can supply power to the mother board.
10. CD Audio Wire Pin: Music can be played with out operating system by using CD Audio Wire. We can connect the CD-ROM and Audio card with the help of this wire.
11. Internal Speaker: It will give some beep sounds, which are used to identify the hardware problems.
12. Chipset North Bridge: It is known as display IC. It is having one heat sink to cool it.
13. Chipset South Bridge; It is known as Audio chip.
SMPS:
Switch Mode Power Supply. Which takes 230v as input and it produces various output voltages according to the devices.
1. CD-ROM: +12v to -12v
2. CMOS Battery: +3.3v
3. Floppy: +5v to -5v
Hard Disk:
It is a storage device. Its access speed is very slow. The speed of this is 7200 RPM for baracode hard disks. My System hard disk capacity is 10GB. We are using ATA66 to connect it to mother board.
CD-ROM:
It is also a storage device. It is a removable disk. The capacity of the CD is 700MB. In general we can write CD only one time. We are using ATA33 to connect it to mother board.
Floppy Drive:
It is a small storage device. In general 1.44MB floppies are used. The Power cable and ribbon label is different from other devices.
