For a LAN, the transmission medium can be twisted copper cable, coaxial cable, optical fiber, and radio. The topology, data rates, and medium access protocols will differ for the different media. LANs can be broadly categorized as baseband LANs and broadband LANs.

What is LAN transmission media?
Transmission media is a communication channel that carries the information from the sender to the receiver. Data is transmitted through the electromagnetic signals. The main functionality of the transmission media is to carry the information in the form of bits through LAN(Local Area Network).
What is WAN transport media?
WANs are most often built using leased lines. A set of switches and routers are interconnected to form a Wide Area Network. 4 WAN Transmission Media. Public Switched Telephone Network High speed, High bandwidth dedicated leased circuits High speed fiber optic cable Microwave transmission links Satellite links.
Which type of transmission is used in LAN?
Figure 1. Interconnection of local area networks (LANs). The common transmission mediums for traditional low-speed LANs are coaxial cable and twisted pairs. High-speed backbone LANs advocate the use of the optical fiber.
What are the main types of LAN media?
Cables are commonly used to carry communication signals within LAN. There are three common types of cable media that can be used to connect devices to a network and they are coaxial cable, twisted-pair cable, and fiber-optic cable.
What is transmission media example?
Describes the type of physical system used to carry a communication signal from one system to another. Examples of transmission media include twisted-pair cable, coaxial cable, and fiber optic cable.
What is transmission media and types?
There are two types of transmission media, namely guided and unguided. Guided transmission media are cables like twisted pair cables, coaxial cables, and fiber optic cables. Unguided transmission media are wireless, such as infrared, radio waves, and microwaves.
What is the difference between LAN and WAN?
LAN is a computer network that covers a small geographic area, like a home, office, or group of buildings. WAN is a computer network that covers a broad area. For example, any network whose communications links cross-regional and metropolitan boundaries over a long distance.
What does LAN stand for?
local area network
A local area network (LAN) consists of a series of computers linked together to form a network in a circumscribed location. The computers in a LAN connect to each other via TCP/IP ethernet or Wi-Fi. A LAN is normally exclusive to an organization, such as a school, office, association or church.
How is LAN different from WAN?
A LAN (local area network) is a group of computers and network devices connected together, usually within the same building.A WAN connects several LANs, and may be limited to an enterprise (a corporation or an organization) or accessible to the public. The technology is high speed and relatively expensive.
What are 3 types of LAN?
Introduction to Types of LAN
- Ethernet. It is a network protocol that controls how data is transferred over a local area network.
- Token Ring. It is a type of local area network in which all devices are connected in a ring arrangement.
- Token Bus.
- Fiber Distributed Data Interface (FDDI)
What are advantages of LAN?
Advantages of LAN
- Resource Sharing. Sharing of resources such as hard disk drives, DVD drives and Printers are made easy in Local Area Network.
- Software Sharing.
- Convenient Communication.
- Centralized Data.
- Improved Security.
- Internet Sharing.
- Computer Identification.
What are the features of LAN?
- Features of LAN are following:-
- Every computer has the potential to communicate with any other computers of the network.
- High degree of interconnection between computers.
- Easy physical connection of computers in a network.
- Inexpensive medium of data transmission.
- High data transmission rate.
What is the difference between STP and UTP?
Shielded twisted pair cable (STP) has the individual pairs of wires wrapped in foil, which are then wrapped again for double protection. Unshielded twisted pair cable (UTP) has each pair of wires twisted together. Those wires are then wrapped in tubing without any other protection.
What are some examples of transmission?
An example of transmission is when something travels over cable wires to get to its destination. An example of the transmission of a virus is when a person spreads a cold virus by sneezing on someone else. Something that is transmitted, such as a message, picture or a disease; the sending of such a thing.
What is another name for transmission media?
The physical means by which data is transmitted from one geographic or electronic location to another is called transmission, or “communication” media.
Which is the fastest transmission media?
Answer: Fiber optics is the fastest of the given data transmission techniques.
What are transmission modes?
Transmission mode refers to the mechanism of transferring of data between two. devices connected over a network. It is also called Communication Mode. These. modes direct the direction of flow of information.
What twisted pair cable?
Twisted pair is the ordinary copper wire that connects home and business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires.
Why LAN is faster than WAN?
while WANs cover larger areas, such as cities, and even allow computers in different nations to connect. LANs are typically faster and more secure than WANs, but WANs enable more widespread connectivity.
Comparison chart.
| LAN | WAN | |
|---|---|---|
| Speed | High speed (1000 mbps) | Less speed (150 mbps) |
What is LAN and WAN in Router?
If you take a look at your wireless router , you may see the abbreviations LAN and WAN, which are often next to some of the ports on the device. LAN stands for local area network, and WAN stands for wide area network.
