Cellular Network

A cellular network is a radio network spread out over land in the form of cells, each of which has a base station permanently installed. Together, these cells offer broader geographic radio coverage. Therefore, even when the user equipment (UE), like a mobile phone, is moving through cells during transmission, communication is still possible. In ...

Data Compression with Arithmetic Coding

Lossless and lossy data compression methods both employ the arithmetic coding process often. The approach uses entropy encoding, where symbols that are seen more frequently require fewer bits to encode than symbols that are seen less frequently. Compared to popular approaches like Huffman coding, it offers several benefits. You will have a thorough knowledge of ...

Service Set Identifier

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 ...

Virtual LAN

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, ...

TACACS+

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 ...

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 ...
