2. Serial Advanced Technology Attachment
It Is A Command And Transport Protocol That Defines How Data
Is Transferred Between A Computer Motherboard And Mass Storage
Devices ,Such As Hard Disk, Optical Devices And Solid State
Devices(ssd).
It Is Having 7 Pins.
Standards Bandwidth Data transfer
speed
SATA I 1.5Gb/sec 150MB/sec
SATA II 3Gb/sec 300MB/sec
SATA III 6Gb/sec 600MB/sec
3. Parallel Advanced Technology Attachement.
Parallel ATA (Parallel Advanced Technology Attachment or PATA)
is a standard for connecting hard drives into computer systems.
PATA devices were originally made using 40- pin ,80-pin.
PATA can transfer data of 133 MB/sec.
4. SCSI(Small Computer
Systems Interface)
It transferring data between computers and peripheral devices.
It connect the devices like Hard drives ,CD-ROM drives, tape
drives , scanner.
This are the some of the SCSI interfaces.
Fast SCSI: 10 MBps; connects eight devices
Fast Wide SCSI: 20 MBps; connects 16 devices
Ultra Wide SCSI: 40 MBps; connects 16 devices
Ultra2 Wide SCSI: 80 MBps; connects 16 devices
Ultra3 SCSI: 160 MBps; connects 16 devices
Ultra-320 SCSI: 320 MBps; connects 16 devices
Ultra-640 SCSI: 640 MBps; connects 16 devices
6. IDE(Integrated Drive
Electronics)
IDE is an interface standard for connection of storages devices
such as Hard Disk Drives (HDD), Solid State Drives (SSD) and
CD/DVD drives to the computer.
In IDE data transfer speed ranges from 100 MB/s to 133 MB/s.
IDE drives are slower than SATA drives.
7. CHIPSET
It manages the data flow between
the processor, memory and peripherals.
It is usually found on the motherboard.
There are 2 types of chipset North Bridge , South Bridge.
Intel® Q670E Chipset.
Intel® W680 Chipset.
Intel® Q670 Chipset
8. NORTH BRIDGE
North bridge is located towards the north of motherboard.
North bridge communicates faster.
The North bridge is hub for memory control.
North bridge connects components like RAM, AGP.
