This document summarizes various computer connectors used for internal and external components. It describes common internal connectors like IDE, SATA, and USB. External connectors discussed include serial ports, parallel ports, keyboard, mouse, video display, Ethernet, and USB. Details are provided on the pin configurations and purposes of different connectors like RJ45 for Ethernet, D-shell for serial ports, and SATA versus IDE connectors for hard drives. In summary, it provides an overview of the most common connector types used in computer systems to connect various internal and external components.

2. CONNECTORS
 A connector join the cable attaches to a peripheral
 One end of cable attaches to the connector on the system unit and
the other end of the cable attaches to a connector on the
peripheral

3. INTERNAL CONNECTORS
• Primary IDE HDD connector
• Secondary IDE HDD connector
• Floppy Drive Connector (FDD)
• USB (Universal Serial Bus)

4. EXTERNAL CONNECTORS
• Serial port connectors
• Parallel port connectors
• Keyboard connector
• Mouse connector
• Video Display connector
• Game / Midi Port connector
• Power connector
• Firewire connectors
• Telephone & Net connector
• USB connectors

5. SERIAL PORT CONNECTOR
 Uses either a 9-pin or 25-pin connector and a cylindrical cable much less
susceptible to interference.
 Can be up to 25 feet long.
 It require 9 pin female connector.
 Use to connect External modems and old mouse.
 Transfer of data at speeds of 28.8Kbps, 33.6Kbps, 56.6Kbps and 128Kbps
and above, they can easily reach the serial port theoretical maximum.

6. Parallel Connectors
 Socket on computer used to connect a printer or other parallel
devices
 Transferring information more than one bit a time
 Developed as an alternative to the slower speed serial port
 Can transfer 8 bits of data (1 byte) simultaneously through 8
separate lines in a single cable

7. USB Connector
 Can connect up to 127 different peripherals together with a single
connector
 Transfers data to a speed of 12 megabits per second
 Replacing the serial and peripheral ports on a PC, at least 4 USB
ports are standard on every computer

8. ETHERNET
 Data width : 1 bit
 Data transfer rate : 10, 100, or 1000 Mbps
 Typical use : networked computers and printers
 peer to peer (so any node can initiate sending data) using Carrier
Sense Multiple Access with Collision Detection (CSMA/CD)

11. EIDE
• EIDE : Enhanced Integrated Device
Electronics
• Data width : 16 bits
• Data transfer : 133 MBps
• Typical use : internal floppy or hard or optical
disk

12. SATA
• SATA : Serial Advanced Technology
Attachment
• Data width : 1 bit
• Data transfer rate : 150 MBps or 300 MBps
• Typical use : hard or optical disk
• The SATA serial port was designed to replace
the slower EIDE parallel port
