A Local Area Network ( Lan )

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.

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

A LAN is a ‘Local Area Network’. It is a small network of computers most often

A: LAN: LAN stands for Local Area Network. LAN is a network which cover a small area like colleges, schools or buildings.

Module 1 establishes the framework of networking standards and protocols for the rest of the class. The module introduces data communications and defines their components and the types of data exchanged. You will learn how different types of data are represented and how data is flowed through the network.

16. Witch of the following statements is true comparing LANs and WANs? LANs generally connect devices that are nearer to each other, compared to WANs. WANs are purchased, and LANs are leased.

Packets also known as frames are grouped amounts of data that are sent across a network. However, packets differ from frames in that a packet contains that data to be sent, including the source and destination Internet Protocol (IP) addresses. A frame is packet that contains the data, the source and destination IP addresses, Media Access Control (MAC) source and destination addresses, and error checking. The MAC addresses are added at the beginning of the data also known as a header. An error checking code is also added to the end of the data which is referred to as a trailer. After the packet has been “framed”, the frame is then sent over the networking medium (i.e. Ethernet cable).

For example, the Sales and Marketing Division has a desktop computer for each of the account representatives. All of these computers are connected to a small local area network (LAN) that serves only the Sales and Marketing Division. The

LANs standards and protocols are Ethernet, IEEE 802.2 [IEEE 802.3, 100BaseT, Token Ring/IEEE 802.5 and FDDI.

It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.

Wireless networking hardware requires the use of underlying technology that deals with radio frequencies as well as data transmission. The most widely used standard is 802.11 produced by the Institute of Electrical and Electronic Engineers (IEEE). This is a standard defining all aspects of Radio Frequency Wireless networking

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.

In order to know and apply the ideas during this chapter, you must be acquainted with basic networking ideas. This includes the functions and options of the TCP/IP protocol suite, technologies like the variants of LAN, synchronous optical network (SONET), and wave division multiplexing (WDM), and therefore the basics of network routing, security, performance, and management.

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.
