A service set identifier’s main purpose is to distinguish one wireless local area network from another that might be simultaneously broadcasting in the same area. A basic service set (BSS), a network of connected clients and access points, and an extended service set cooperate with a service set identification.A basic service set is a subset ...
HTTP (Hypertext Transfer Protocol) and FTP (File Transfer Protocol) are the two internet protocols that are used to transfer data between a client and a server. Both of these protocols operate on the Application Layer of the OSI model. We also have a separate article OSI-Model where you can read about the OSI Model and ...
A VLAN or Virtual Local Area Network is a customized network built from one or more local area networks. It allows a group of devices from different networks to be integrated into a single logical network. As a result, a virtual LAN is created that can be managed just like a physical LAN. Without VLANs, ...
Terminal Access Controller Access-Control System (TACACS) refers to a family of connected protocols handling remote authentication and connected services for network access management through a centralized server. The initial TACACS protocol, which dates back to 1984, was utilized for communicating with an authentication server, common in older UNIX networks or other operating systems as well ...
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 ...
