Lossless compression and lossy compression are two methods that can be used. In contrast to lossless compression, which preserves all data, lossy compression shrinks the size of the data by deleting extraneous information.For lossless data compression of multimedia, the Shannon-Fano Algorithm is an entropy encoding method. It gives each symbol a code depending on how ...
A routed protocol allows for data routing. IP and AppleTalk are two examples of routed protocols. An addressing method is necessary for such a protocol. You may determine the network that a host belongs to as well as where that host is located on that network by using the addressing scheme. A routed protocol can ...
The sliding window protocol is a data link layer protocol that is useful in the sequential and reliable delivery of the data frames. Using the sliding window protocol, the sender can send multiple frames at a time. The sliding window protocol uses a mechanism of sequence numbers. The sender associates a sequence number to the ...
Multiplexing is a technique that allows different analog and digital transmission streams to be handled at the same time across a shared link. Multiplexing converts a high-capacity medium into a low-capacity logical medium, subsequently shared by multiple streams. The process of combining data streams or input is called Multiplexing, and the hardware used for multiplexing ...
TCP congestion window and congestion policy are used to avoid network congestion. As the network is the main component in wireless communication, any congestion in a network must be avoided. If the data sent by the sender is not delivered by the network, it must inform the sender about it. The network, other than the ...
Distance vector is the “Dynamic Routing” protocol. Distant vector protocol also called as Bellman-Ford algorithm used to calculate the shortest path. What is Distance Vector Routing (DVR) Protocol? Distant vector routing protocol also called as Bellman-Ford algorithm or Ford Fulkerson algorithm used to calculate a path. A distance-vector protocol calculates the distance and direction of ...
SONET (Synchronous Optical Network) is a standardized form of protocol that is used in digital communication between the sender and the receiver. It uses a fiber optic medium to transmit a huge amount of data across a large distance. SONET helps us to transmit data over larger distances with greater data transmission rates. We have ...
In computer networking, a collision happens when multiple devices attempt to transfer data via a commonly shared circuit. In a common circuit, various devices may listen at the same time, but only one device at a time is allowed to transmit data. This requires that all other devices listen to the transmission. Many devices are ...
Throughput in computer networking is the rate of successful transmission of messages over a channel of communication, such as packet radio, Ethernet, etc. The data contained in these messages may be delivered through network nodes, or over logical or physical links. Throughput is mostly measured in B.P.S. (Bits Per Second). The throughput of a network ...
An electrical cable with copper as a conductor material, a shielding of insulator material, and a braided mesh metal is known as a coaxial cable in computer networks. A coaxial cable is also known as a coax. The coaxial cable supports high-speed signal transfer over a larger distance as compared to other cables like twisted ...
