What is the difference between Serial transmission and parallel transmission? Answer: Digital data transmission can occur in two basic modes: serial or parallel. Data within a computer system is transmitted via parallel mode on buses with the width of the parallel bus matched to the word size of the computer system. Data between computer systems is usually transmitted in bit serial mode . Consequently‚ it is necessary to make a parallel-to-serial conversion at a computer interface when sending

Kelly Ouimette NT1110 January 28‚ 2014 Unit_4_Researcher_Paper_1_Port_Expander (en.wikipedia)A port expander is computer hardware that allows more than one device to connect to a Single port on a Computer. The Commodore VIC-20 used a port expander to allow more than one Cartridge to be connected to the single ROM cartridge port. A port expander can be any device to which one existing or onboard port becomes two or more. E.G. a KVM switch or a USB hub. One advantage is the ability

A Port Expander is a hardware device that allows a user to use more than one device on a single port. A good example of a port expander is a USB hub. Most USB hubs allow you to hook up 3 to 5 USB connections from only 1 USB port on your computer. The disadvantage of using a port expander is speed. The single port you are connecting to only operates at a set speed; example of this is a USB 2.0 port operates at 480 Mbit/s. If you have a portable hard drive that runs at 300 Mbit/s and a digital camera
