Local Area Network (LAN) for DesignIT‚ a Local Area Network (LAN) is a network of computers‚ and other network devices such as printers which exchange data‚ and are located under one roof. LAN networks are mostly used in small organizations or small businesses. The computers in a LAN communicate through protocols and share data such as files and emails. Every computer in a network is assigned a unique Internet Protocol (IP). When a computer communicates by sending a request to the LAN network‚ it is routed

Looking at a particular floor in a particular building‚ all the devices connect to either a single Ethernet switch or single wireless access point‚ both of which sit in a wiring closet in the middle of the space. Which of the following is true about the distance limitations in this LAN? C. All Ethernet user devices can be up to 100 meters away (but no farther)‚ while WLAN devices must typically be

The relatively large colleges with 3 buildings have 3 separate LANs each. One LAN on each building. Each LAN is connected to the other through a router that is connected to the BN. 3. All other buildings are connected to the BN through a router. 4. Assuming one router supporting the BN. It will be assigned the IP address 128.100

LOCAL AREA NETWORK (LAN) A Local area network is a network that is confined to a relatively small area. It is general limited to a geographic area such; school‚ writing lab‚ building‚ office‚ or hall. A local area network’s linkages usually are accomplished with either telephone‚ coaxial‚ or fiber-optic cables. This network are privately own networks with and angle building or campus of up to a few kilometers in size. They are widely used to connect personal computers and work situation in company

4. The Medium Access Sub Layer Broadcast channels [or multi-access channels] are a category of networks and the key issue is how to determine who gets to use the channel when there is competition for it. The protocols which define these factors belong to a sub layer of data link layer called the MAC(medium access control)sub layer. ALOHA: Norman Abramson devised a new and elegant method to solve the channel allocation problem called the “ALOHA” system which used ground-based Radio broad

The three main domains affected by the “Internal Use Only” are the User Domain‚ Workstation Domain‚ and the LAN Domain. 1. User Domain: This Domain is where only one user will have access to it. This can be configured to internal use only. By default‚ the IT department tries to maintain a certain level of Security for this‚ so that nobody can access from the outside‚ only the IT Department can grant access privilege for Remote Access Point. The User Domain will enforce an acceptable use policy

wireless LAN can effectively reach and be used to send and receive data between the WLAN’s APs and its clients. Shared bandwidth: A term referring to how some networks must share the right to send data by taking turns‚ which limits the total number of bits sent by all devices (the network’s total capacity). Wi-Fi: A term created by the Wi-Fi Alliance as part of its overall wireless LAN branding and marketing strategy; this term has become somewhat synonymous with wireless LAN over time. LAN edge: A
