The switches are a crucial element of networking hardware used in Ethernet networks to ensure device connectivity. It is considered a network’s brain since it effectively connects devices using hardware addresses. Due to their increasing importance, switches are now manufactured in various configurations and specifications. A switch contains numerous ports where computers can be connected. ...
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 ...
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 ...
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, ...
Spanning Tree protocol is a link management protocol. It is used for creating a loop-free network. It is also a layer-2 protocol that runs on bridges and switches. In IEEE standard, it is standardized as IEEE 802.1D. Introduction What is STP? STP is a link management protocol and also a layer 2 protocol. STP generally ...
Fragmentation is a process that divides packets into smaller pieces (fragments) so that the resulting pieces can travel across a link with a smaller maximum transmission unit (MTU) than the original packet size. The network layer fragments data when the maximum size of a datagram exceeds the maximum size of data that can be retained ...
Whenever a sender and receiver have a radical link to transmit data/information packets, the data link management is enough to handle the channel. Assume there is no committed path to communicate the data between 2 devices. In this case, with multiple access protocols, the channel at the same time transmits the information over the channel. ...
At the receiver end the data bits stream, received from the physical layer is divided into the frames on the data link layer. Data frames can have fixed or variable length sizes. The size of every frame is different in variable framing so bit patterns are used in starting and end of the data frame. ...
