• Purpose of a LAN (hosts, devices (dual functions), examples of LAN use, types of resources shared, information that can be accessed using a LAN, purpose of LAN components) AND advantages and disadvantages of cable, fibre, wireless in terms of bandwidth, location, security, reliability, set up, suitability
Describe what the user will mainly use a specific LAN for When the first computers were made, they couldn’t talk to each other if they weren’t the same type. But now with the standardising of components, it is now easier than ever for different computers to connect to each other in a LAN (Local Area Network).
A LAN is a network of computers in a specific area interconnect using a variety of network media. For example, WBHS LAN are all the computers connected to the WBHS network via Ethernet, Wi-fi or other. This is different from a WAN (Wide area network) which extends to a much wider area such as a town, city and country. LAN are usually more restricted in access and more numerous.
LAN are used at WBHS to connect all the schofols desktops, servers, all-in-ones, printers, laptops and many other devices to each other. For students using BYOD, this gives them access to restricted Wi-Fi, but for teachers and users on the schools computers, this allows them to access network drives, print to any printer, send emails internally – just to name a few. Because the Network in local and internal, WBHS doesn’t rely on external severs which
4)LAN (Local Area Network)-A LAN is a group of computers or devices connected together through a local network.LAN connections are usually very inexpensive.They are also usually very fast.LAN connections are usually within the same building.
In the Network Design Paper I will explain how the University has recently leased a building in Adelphi, Maryland. The measurements of the University is 240 feet long, 95 feet wide and 30 feet tall and broken down to two different floors. This University will be used for education purposes of course, the facility will be made of six instructional labs, seven offices, library, five classrooms, a student lobby and a computer lab. There will be a server room on each floor. The purpose of this paper is to explain the design of the networks in this building. The student accessed computers will be set up on a separate network than the network that they staff will be using.
2. What is the difference between a WAN and a LAN? Which type of network is the Internet? Which type of network is the classroom network?
Describe the data communication types used historically and the developments that have led to modern day Local Area Networks (LANs). Detail any emerging technologies and where you think data communications are likely to be in ten years’ time.
A LAN is a ‘Local Area Network’. It is a small network of computers most often
When setting up a LAN the architecture that you decide to choose is important. There are several factors that are decided when choosing said architecture, some of these being network speeds, types of cables, and access control mechanisms like collision detection (Team, 2011). The most common on in today’s LANs is Ethernet. These can be either wireless, wired, or a hybrid of both.
A LAN networks job is to link computers together through a central device. That central device is the router, it is what transfers data to and from computers with an Ethernet cable or wirelessly as long as you are connected to the network. When you connect to the internet you are actually connecting to millions of networks that are connect through a multitude of ways: telephone lines, cable, and even fiber optic lines. A LAN and the Internet are the same only in the way that they both need a router to, well, route traffic. You actually can incorporate the Internet access into a LAN. The modem must be connected to the router and then that will provide a gateway between the Internet and the network connection. A firewall is very important
A Wide Area Network ( WAN) is a computer network covering multiple distance areas, which may spread across the entire world. WANs often connect
Ethernet is typically the technology that is used to allow computers locally to communicate with one another. Computers that are close to each other they are connected by Ethernet.
6. Why is Ethernet technology more appealing to users than the rest of the LAN technologies?
Computer Network: A LAN (local area network) that connects computers in a house, at school or at work.
LAN stands for Local Area Network. LAN is a type of network that interconnects computers and devices either wired or wireless and covers a greater distance. LAN is mainly used in private organisations such as college or university. More or less everyone uses wireless router at home these days and the user is able to connect between 5-10 devices wirelessly. The user can share the broadband or the connection with ADSL by using Ethernet cables. Smaller LANs can connect at least
LANs standards and protocols are Ethernet, IEEE 802.2 [IEEE 802.3, 100BaseT, Token Ring/IEEE 802.5 and FDDI.
Local area networks (LANs). DEFINITION The concept of local area networks (LANs) is not new. It represents a logical development of computer technology. With the advent of microcomputers in the 1980s many office workers began bringing their own disks into work, compromising data integrity.
All the computers, in the logically and physically networks have to follow the same rules known as Protocols such as TCP/IP, IPX/SPX and NETBEUI etc. Today, there are many computer networking technologies such as LAN, MAN, WAN, WLAN, ISDN, ATM, Frame Relay, X.25, Bluetooth,
