What are the three elements that determine the characteristics of a local area network?

1) a medium for transmitting data, (2) a topology for connecting various devices, and (3) a medium control method for sharing resources.

The LAN uses carrier interception multi-access conflict detection, token ring access control method, and token bus access control method.

The characteristics of the LAN are as follows:

The geographical area covered is smaller, generally 10m 10km (such as an office building, an enterprise, etc.), usually owned by a single unit.

Networking with a specially laid transmission medium with high data rates (10MB s to 10GB s).

The communication delay time is short and the reliability is high.

A LAN can support a variety of transmission media.

The topology of a LAN is mostly bus, ring, or tree.

LAN generally uses packet-switched technology.

LAN often uses broadcast or multicast for data transmission.

Workstations on the LAN are on an equal footing and work in a competitive and collaborative manner.

1. Small coverage.

Such as one or a group of buildings. Networking with a specially laid transmission medium with high data rates (10MB s to 10GB s).

2. Reliable and stable.

The communication delay time is also very short, the reliability is high, and the LAN can support a variety of transmission media.

The characteristics of the local area network: 1. The geographical scope covered is small, and it is only connected in a relatively independent local range, such as one or a concentrated building complex; 2. Use a specially laid transmission medium for networking, and the data transmission rate is high (10MB S 10GB S); 3. The communication delay time is short and the reliability is high; 4. LAN can support a variety of transmission media.

Network topology, transmission media, and media access control methods.

The local area network can be connected with the remote local area network, database or processing center through the data communication network or special data circuit, forming a large range of information processing system. LAN enables functions such as file management, application software sharing, printer sharing, scanner sharing, scheduling within workgroups, e-mail and fax communication services, and more.

Network topology.

Transmission medium. Media access control methods.

Topology, transmission media, and network protocols.

1. The flutter structure includes various forms such as star, bus, ring, tree, etc., which determines the connection mode and communication mode between the devices.

2. The transmission medium refers to the medium required to transmit data, including twisted pair, optical fiber, etc., and different transmission media determine the transmission speed and distance of data in the LAN.

3. Network protocol is the key factor to measure the performance of LAN, and different network protocols have different characteristics such as transmission efficiency, data transmission fault tolerance and network security.

A local area network is a small-scale network that interconnects various devices and computers through communication lines for information exchange.

The typical characteristics of a LAN are ().

a.High data rate, wide range, high bit error rate.

b.Low data count, small range of dust travel, low bit error rate.

c.High data rate, small range of stools, low bit error rate.

d.Low data rate, small range, high bit error rate.

Correct answer: High data rate, small range, low bit error rate.
