Packet Flow in the Same Network

For transferring a packet from the source host to the destination host in the network we require both the MAC and IP address of the destination host. ARP (Address Resolution Protocol) is a protocol from the second layer i.e, the Data link layer in the OSI model that connects a dynamic Internet Protocol (IP) address ...

Frequency Division and Time Division Multiplexing

The signal transmission over various channels can be performed in two different ways namely – Frequency division and Time division multiplexing. In frequency division multiplexing, we transfer many signals at the same time and each source transmits its signals in its allocated range of frequency. In the time division multiplexing, the transmission time is divided ...

Data Link Layer in OSI Model

What is the Data Link Layer Protocol? Some Common Data Link Protocols are: Functions of Data Link Layer 1) Framing and Link Access 2) Reliable Delivery The Data Link Layer provides a guaranteed delivery service, i.e., it transmits network layer datagrams without error. Transmissions and acknowledgments are used to provide a reliable delivery service. A data ...

LiFi vs WiFi

WiFi stands for Wireless Fidelity, while LiFi stands for Light Fidelity. LiFi and WiFi are both primarily utilized for internet-based applications. LiFi employs light as a medium for data transmission, whereas WiFi uses electromagnetic waves at various radio frequencies. Light experiences less interference than radio waves and can therefore be employed in settings with greater ...

Collision Domain and Broadcast Domain

To analyze the working and efficiency of the network devices, various metrics (a metric is defined as a standard or system of measurement) are used. The collision domain and the broadcast domain are two of those metrics. A collision domain is measured by finding out the number of devices whose signals collides with each other ...

Shannon-Fano Algorithm for Data Compression

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 ...

Routed Protocols vs Routing Protocols

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 ...

Sliding Window Protocol

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 in Computer Networks

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 ...

Congestion Control

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 ...
