Universal Serial Bus Ports Essay - 708 Words

[Type the company name] | Video Summary 1 | Unit 3 Assignment 1 | | Serial, Parallel, and Game ports have for the most part been replaced by USB ports. USB or Universal Serial Bus is less bulky, faster, can be hot swapped, and up to 127 devices can be used. Early Mice used serial connectors and keyboards used a 5 pin bulky DIN connector. Modern Mice and Keyboards use PS/2, USB, or wireless type connectors. A NIC or Network Interface Card is what connects your computer to a local or distance network or the internet. The NIC converts parallel signal from the motherboard system bus into serial signal for the internet cable. A dial up Modem is used to connect to the internet. At speeds of 56kbps, it is the slowest way to†¦show more content†¦It’s also good to know that all printers use different kinds of interfaces. Remember when installing a printer to always run the installation CD first.

Theoretically, if the host microcontroller used follows the USB 2.0 high speed standard, the speed of data transfer should be much faster than the computer since there is no associated overhead in the bus compared to the computer. The main objective of this study is to develop a device that can transfer files from flash drive to flash drive.

BUS TECHNOLOGY 4. At one time, bus (Annex 1-a) meant an electrically parallel system, with electrical conductors similar or identical to the pins on the CPU. This is no longer the case, and modern systems are blurring the lines between buses and networks. 5. Buses can be parallel buses, which carry data words in parallel on multiple wires, or serial buses, which carry data in bit-serial form. The addition of extra power and control connectionsRead MoreThe Parts of a Computer563 Words   |  2 Pageshardware components at a steady temperature to allow continuous processing.

Digital data transmission can occur in two basic modes: serial or parallel. Data within a computer system is transmitted by 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. It is necessary to make a parallel-to-serial conversion at a computer interface when sending data from a computer system into a network and a serial-to-parallel conversion
