flexibility, performance improvement, and savings on cost. With flexibility you can move users to new locations without reconfiguring the system. The VLAN improves performance by segmenting broadcast traffic into port groupings, this helps to preserve network bandwidth and save processor time. The last benefit is cost savings; VLANs will eliminate the need to use routers to partition LANs into multiple broadcast domains, thus reducing hardware costs. Let’s look at the security aspect of a VLAN; one

Computer A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. A computer can process data, pictures, sound and graphics. They can solve highly complicated problems quickly and accurately. Block Diagram Input Unit: Computers need to receive data and instruction in order to solve any problem. Therefore we need to input the data and instructions into the computers. The input unit consists of one or more input devices
