What are the different types of data transmission speed or bandwidth?
Data transmission speed is the rate of transferring data from source to destination. It is also referred as Bandwidth. Unit
Write short note on Bus topology with advantages and disadvantages
Unlike star or mesh topology, a bus topology is a multi-point connection between the nodes or devices on the network. A long cable works as backbone of the network. All the different nodes in the network connects at different points on the main cable. A connection point in the main cable for a node or device is the nearest point for the node.
Write short note on Star Topology with advantages and disadvantages
Star topology is one of the four basic topologies of network communication. In star topology, all network devices connects to a controller or hub. This controller or hub enables communication among the network devices. Devices does not connect directly to each other as in Mesh topology.
Write short note on Mesh Topology with advantages and disadvantages
Mesh topology is one of the four basic topologies of network communication. This is a point-to-point connection. That means, each devices in the network connects to each other device directly. Mesh topology offers speedy connection between devices due to dedicated communication channel.
What are the 2 types of connection in network systems?
A network system enables data communication between 2 or more devices. Communication links or channels connects these devices. This link or communication cannel can be of 2 types; point-to-point and multipoint connection. Both of these connections has their advantages and disadvantages and use cases.
What are the three types of transmission modes? Write short notes with advantages and disadvantages.
Based on the direction of data from sender to receiver, there can be 3 types of transmission modes which are simplex, half-duplex, duplex
What are the 3 Criteria necessary for an effective and efficient network
A network must meet a 3 criteria to become useable in real world situation which are Performance, Reliability and Security.
4 fundamental characteristics of Data Communication System
Data communication systems enable transfer of data using one of the three transmission modes. Data communication systems has 4 fundamental characteristics; which are delivery, accuracy, timeliness and jitter.
5 Components of a Data Communication Network
Systems that facilitates this movement of data between devices or end-points are called data communication network. There are 5 components of a data communication network which are data, sender, receiver, transmission medium and protocol.
