Answers and Explanations Data related Questions. 1. Sub netting / VLSM Subnetting allows you to create multiple logical networks that exist within a single Class A‚ B‚ or C network. If you do not subnet‚ you are only able to use one network from your Class A‚ B‚ or C network‚ which is unrealistic. VLSM (Variable Length Subnet Mask) When we perform Subnetting most of the time each subnet has the same number of available host addresses. You can need this in some cases‚ but‚ in most cases

It is important to test the cables before you install them and after they are installed. Although there are many tools that are used for testing the cables in a network this paper is only going to talk about three. The first one is the multifunction cable scanner‚ they are available for testing both copper and fiber optic cable. One such model is the Hobbes 258898 it can test every pin of almost 20 often used cables from coax to 40 pin ribbon cables. It identifies opens‚ shorts and mis-wires at

ABSTRACT In the world of technology‚ Universal Serial Bus (USB) is a serial bus standard to connect devices to a host computer. USB was designed to allow many peripherals to be connected using a single standardized interface socket and to improve plug and play capabilities by allowing hot swapping; that is‚ by allowing devices to be connected and disconnected without rebooting the computer or turning off the device. Other convenient features include providing power to low-consumption devices‚

FAST CRAM Printer Types Dot Matrix • An impact printer that transfers characters by striking a pattern (from a matrix) through an inked ribbon and onto paper. • The most common number of pins on a dot matrix printer is 9‚ 18‚ or 24. • The speed of dot matrix printers is measured in characters per second (CPS). Common speeds for a dot matrix printer are 32 to 72 CPS. • Dot matrix printers can use either a friction feed or a tractor feed system to move paper through the printing
