Assignment # 5

USB: Using an USB cord you can connect external devices to the computer to either transfer or input data onto the computer. As well it is possible to output data onto the device using the USB port.

Strengths: Can carry any kind of data; radio, television, music, etc., can carry small electrical charges that can power many things that usually would have to be powered by batteries, the connectors are designed to not break; there are not any pins on the sides of them to make them break easily.

Weaknesses: Can transfer viruses from one computer to another computer or to external devices linked by a USB cord, and the physical connectors are troublesome because there are many different sizes of USB connectors and not all of them fit every device/ computer.

Parallel: a port that is a type of socket found on PC's for interfacing various peripherals.

Strengths: none they are out of date

Weaknesses: has a lack of true bidirectional capability, faster than serial ports but slow to modern standards, and expensive.

SCSI: (Small Computer System Interface)- a set of standards which physically connects and transfers data between computers and peripheral devices.

Strengths: Its support for a large number of devices on the bus, can handle up to 160MBps in data transmissions, and any device can use SCSI.

Weaknesses: The bus width, transfer modes and signalling modes, and the cable length.

Firewire: A very fast external bus that supports data transfer rate up to 400 MBps.

Strengths: One of the fastest peripheral devices developed, can move large amounts of data between computers and peripheral devices, and it enables an easy connection of digital consumer products.

Weaknesses: Space constraints and compatibility
