What is the device that passes data from one network to another?

What is the device that passes data from one network to another?

network switch
A network switch connects devices within a network (often a local area network, or LAN*) and forwards data packets to and from those devices.

What connects computers with cables to share information?

A Local Area Network (LAN) connects two or more computers together via Ethernet cables. For office networking, this is one of the most common network types, because of its reliability, stability and performance.

What is node and link?

Answer: A node is an individual processing unit , it has capabaility to communicate with other nodes on demand , process the information it receives. A link is a physical and logical network component used to interconnect hosts or nodes in the network.

Which communication system send and receive the data from both the devices?

11.4.3 Full-duplex Communication It is two way or bidirectional communication in which both devices can send and receive data simultaneously, as shown in Figure 11.5. It is like a two way road where vehicles can go in both directions at the same time.

Do switches have IP addresses?

But since the switch does not have the capability to assign IP addresses, the computers connected to it will not be able to communicate with each other. They will get an Automatic Private IP Address (APIPA). You need to assign a static IP address to your computers.

Why use a switch over a router?

While a network switch can connect multiple devices and networks to expand the LAN, a router will allow you to share a single IP address among multiple network devices. If you have the need for more connections, an Ethernet switch may be a better option over a hub.

Which cable is used in LAN?

Ethernet LAN Media and Cable Lengths. 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.

Is a device that allows communication with other computer?

A router is a communications device that connects multiple computers or other routers together and transmits data to its correct desti- nation on the network. A router can be used on any size of network. These routers connect from 2 to 250 computers.

What do you mean by node link diagram?

Description. Also known as Network Graph, Network Map, Node-Link Diagram. This type of visualisation shows how things are interconnected through the use of nodes / vertices and link lines to represent their connections and help illuminate the type of relationships between a group of entities.

What is the link between two nodes?

A link (or edge) of a network (or graph) is one of the connections between the nodes (or vertices) of the network. Links can be directed, meaning they point from one node to the next, as illustrated by the arrows in the first figure below.

What are the 4 fundamental characteristics of a data communication?

The effectiveness of a data communications system depends on four fundamental characteristics: delivery, accuracy, timeliness, and jitter.

What is data communication block diagram?

The block diagram of a communication system will have five blocks, including the information source, transmitter, channel, receiver and destination blocks. The information source converts this information into physical quantity.

What are the different types of network cabling?

Explanation: Network cabling include different types of cables: UTP cable consists of four pairs of color-coded wires that have been twisted together and then encased in a flexible plastic sheath. STP cable uses four pairs of wires, each wrapped in a foil shield, which are then wrapped in an overall metallic braid or foil.

What makes a one of a kind computer network?

A one-of-a-kind computer network which includes sending and receiving hardware, transmission and relay systems, common sets of standards to all the equipment can “talk” to each other, and communications software. network protocol rules for how data is handled as it travels along a communications channel.

What is the primary role of the physical layer in transmitting data on the network?

What is a primary role of the Physical layer in transmitting data on the network? create the signals that represent the bits in each frame on to the media Explanation: The OSI physical layer provides the means to transport the bits that make up a frame across the network media.

What kind of signal is transmitted from a cell tower?

signals transmitted by using cell towers; several generations from 1G (analog) to 4G (digital data at speeds up to 15 Mbps) microwave a high-frequency radio signal that is directed from one microwave station tower to another (signals cannot bend) satellite communications
