List some characters of serial ports
-connects external devices like modems, mice, or keyboards
-available in 9 and 25 pin models
-transmit data one at a time
-transmit data at 115 KB/sec.
List some things about USB ports and cables
-are versatile connectors used for connecting peripherals, data transfer, device charging, and power delivery.
-are industry standard for short-distance digital data communications
-They can be wired or wireless, with the wired version involving USB ports and cables.
List some features of fire wire ports and cables
-developed by Apple in the late 1980s and early 1990s.
-connects camcorders and video equipment to computers, with three variants available.
-can transfer up to 400 megabits per second
- is an industry standard on non-Apple computers.
What are some characters of parallel ports and cables?
- are used for connecting scanners and printers.
-can send several bits at the same time and it’s speed is much higher in comparison with the serial port
-it’s a 25 pin model
-The older type was Centronics 36 Pin Port before being replaced by the DB-25 port with a parallel interface.
The Ethernet port provides a data travel speed of
10 Mb to1000 Mb per secound
What is the SCSI( small computer systems interface)
is technology designed to connect smaller devices to a computer
The SCSI is controlled by?
-by a host controller which will typically be built into the motherboard, or it can be from a separate expansion card
The connector /cabling requirement for an SCSI depend on?
Whether the connection is external or external or the location of the bus
List the signaling types used by SCSI
-Single-Ended (SE),
-Differential (HVD or high-voltage differential),
- LVD (or low-voltage differential).
Fast scsi
10 MBps; connects eight devices
Fast Wide SCSI
20 MBps; connects 16 devices
Ultra-Wide SCSI
40 MBps; connects 16 devices
Ultra3 SCSI
160 MBps; connects 16 devices
Ultra-640 SCSI
640 MBps; connects 16 devices
List some characteristics of PS/2 ports and cables
-It was invented by IBM
- It is a 6 pin mini Din connector
-there are two PS/2 ports on a computer: one for the keyboard (usually purple) and one for the mouse (usually green)
List some characters of a VGA port
- is the oldest video connector still in use today
-Introduced by IBM
-was the standard for connecting the then common CRT monitors to computers
-It has 15 pins, divided into three rows, and is contained in a D-sub connector. The end adapter is typically a blue color and consists of two thumbscrews to lock the connector in place to prevent it from disconnecting accidentally
-carries analog video only and no audio
