These network devices connect two separate networks and provide connectivity between them at the data link layer of an OSI model. inocta https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1418926711 2021-04-15 00:31:40 UTC https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1418926711 Transparent Bridge-It's an invisible computer network bridge, as the name implies. inocta https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1418935652 translational bridge-plays a key role in changing a networking system from one type to another. These bridges connect two separate networks, such as token ring and Ethernet.
Source Route Bridge-IBM developed the Bridge technique, which is one of the Token Ring network techniques. The complete frame route is contained in one frame in this bridge.]]> 2021-04-15 00:34:53 UTC https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1418935652 ADVANTAGES inocta https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1418985583 1.Bridges are often used as repeaters to expand a network. Bridges may be used to link networks with different architectures.
2.In general, network reliability is high in a bridge, which makes network maintenance simpler. Additionally, by splitting a LAN into small parts, network congestion can be minimized.]]> 2021-04-15 00:53:03 UTC https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1418985583 DISADVANTAGES inocta https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1418990279 1.A bridge, on average, is more expensive than the hub and repeaters. That is why it is only used when there is a lot of LAN network traffic. In other cases where the data load is variable, a hub or a repeater should be used.
2.Speed
 
A bridge does more buffering of frames and introduce more relays. This makes them slower compare to a repeater.

2.Full Duplex Modem-These modems can send and receive data in both directions at the same time. They also employ two carrier frequencies, one for each direction of travel.
3.Asynchronous Modem-These modems can send and receive data in both directions at the same time. They also employ two carrier frequencies, one for each direction of travel.]]> 2021-04-15 01:02:23 UTC https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1419010346 ADVANTAGES inocta https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1419025295 1.A modem modulates and demodulates electrical signals sent over phone lines, coaxial cables, and other types of wiring; in other words, it converts digital data from your device into analog signals that can be transmitted over wires, and it can also convert incoming analog signals back to digital data.
2.Signal Conversion-A modem converts digital signals into analog signals when they are sent by a device.

Although external modems do not allow mobility, all internal modems do. Internal modems can be used to access the internet wirelessly. However, this necessitates a lot of electricity, and the link can become slower as a result.
2.Maintenance of the traffic flow

A modem interferes with traffic between a LAN and the internet. As a result, it is unable to maintain traffic.]]> 2021-04-15 09:31:31 UTC https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1420226233 What is repeater? inocta https://padlet.com/inocta/o1r5d6pz9ebtynp9/wish/1420229666 A signal repeater is an electronic system that receives and retransmits a signal.
