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 ...
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 ...
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 ...
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 ...
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 ...
The Diffie-Hellman Algorithm is a secure way of cryptographic keys exchange across a public channel. It was among the very first public-key protocols. Ralph Merkle came up with the Diffie-hellman key exchange and it was named after Whitfield Diffie and Martin Hellman. Within the fields of cryptography, DH (Diffie-Hellman) is the earliest example of public ...
A communication protocol used in local area networks is called the Token Ring protocol (LAN). The topology of the network determines the sequence in which stations send in a token ring protocol. A single ring of connections connects all of the stations. It makes use of a unique three-byte frame known as a “token” that ...
HTML (Hyper Text Markup Language) and HTTP (Hypertext Transfer Protocol) are two completely distinct technologies. HTTP is an application protocol that governs how information travels on the World Wide Web, whereas HTML governs how Web pages are formatted and displayed. HTTP protocol determines how Web data is moved around the internet, whereas HTML is the ...
Routing is the process of choosing the path in the network. Distance vector routing is the routing protocol that selects the path based on parameter distance. Link State routing protocol is the protocol that chooses the best path based on the cost of the path. Introduction to Routing Routing decides the best path for the ...
Data overflow occurs when a device receives too much data before it can handle it. Flow control instructs the sender how much information should be transferred to the recipient. This allows the data to be processed at an effective rate and prevents data loss or retransmission. There are mainly three types of flow control. In ...
