LAN

• Local Area Network (LAN) is a collection of computers and peripheral devices such as routers, switches, cables, access points and other components that are connected together within a limited area such as home, school and an office building
• LAN- It is a privately owned network where anyone can create it using a central device such as a hub or a switch and cables like the ethernet cable that are capable of transferring data up to 1000 Mbps:
• Benefits of Using LAN Multiple devices can share a single internet connection Sharing of files, printers and other shared devices Has access to all applications located in a server Can protect all devices connected to LAN using security tools or applications
• Client/Server LAN consists of several devices (called as clients) and a main server that are connected to a switch
• Client/Server LAN -Business organizations use this type of LAN where all the business data is stored in a server. The clients are connected using cables or wireless connections where they can access data and applications from the server
• Peer-to-Peer LAN- are smaller types of LAN that is commonly used at homes where all devices are connected and can exchange data without using a server. All devices. such desktop computers and laptops can share data through cables or wireless. connections using switch or hub.
• LAN topologies shows an outline on how devices are connected in a LAN. It also shows how data is transmitted from one device to another device. The common examples of topologies are star, ring, mesh, bus and tree.
• End Points- It includes personal computers, phones, tablets, printers, servers or any other devices that you use.
• End points - Servers are the data centers that store data which can be shared to other devices. Servers provide information. while other devices retrieved information. End points can provide and retrieve
• NIC (Network Interface Card)- A circuit board that is inserted to PC/ Workstation or server where LAN cables are connected whether wired or wireless that converts data either electrical, light or radio signals.
• Network Media- provides data from the NIC on one device is transferred to another device using LAN cable for electrical signals, optical fiber for light. signals and air for radio signals.
• Connector-provides connection points (RJ 45) to a network media (example: UTP Cable) that can be embedded to the NIC.
• . Switch- It is a multiport device where multiple devices are connected to ensure that data is sent to the right destination in a local area network. SOHO (Small Office/ Home Office) typically use this type of device.
• Router- It is where a switch is connected to access the internet.
