The IEEE 802.11 standard specifies the structure and specifications for wireless local area networks (WLANs). For LAN device connectivity, WLAN or WiFi uses high-frequency radio waves rather than cables. Within the network coverage region, users connected via WLANs can roam about. The MAC layer provides the capability for various tasks, such as controlling medium access, and can also ...
Net Neutrality is the idea that internet service providers such as Reliance Jio and Indian Airtel should treat all content streaming through their cables and mobile towers equally. This means they should not be able to move some data into fast lanes while blocking or otherwise discriminating against other data. In other words, these businesses should not be able ...
The transport layer is one of the seven OSI (Open Systems Interconnection) model layers, which manages end-to-end communication in computer networks. It sits above the network layer and below the session layer and manages end-to-end communication between devices in a network. What is the transport layer? The transport layer in computer networks is a crucial ...
The Two Generals’ Problem, also known as the Two Generals’ Paradox or the Two Generals’ Dilemma, is a thought experiment and a famous problem in computer science and distributed systems. While it is not particular to TCP (Transfer Control Protocol), it is a notion that pertains to the issues of reliable communication in distributed systems, ...
A transmission media in data communication is a physical path between the sender and the receiver and it is the channel through which data can be sent from one location to another. Data can be represented through signals by computers and other sorts of telecommunication devices. These are transmitted from one device to another in ...
Linus Torvalds created Linux entirely from scratch. It is created as open-source software, which is inherently very strong and secure. Anyone can install Linux and modify it to create their own Linux version. These Linux versions are known as “distros” or “distributions.” The Linux kernel’s unrivaled security and reliability, combined with its open-source nature, make it one of ...
Enhanced Interior Gateway Routing Protocol (EIGRP) is a dynamic network-layer protocol with protocol number 88, initially a Cisco proprietary system but transitioning toward an open standard. EIGRP facilitates classless routing, VLSM, route summarization, and efficient load balancing. Unlike earlier protocols like IGRP or BGP, EIGRP enhances data exchange efficiency among routers. Born from Cisco’s 1990s initiative ...
When a device is within its home network in an IP network, routing is based on static IP addresses. The IP address assigned to the device on the network connects it to the network via standard IP routing. This is similar to how a postal letter is delivered to the specified address on the envelope. ...
Access Control Lists (ACLs) are a collection of permit-and-deny restrictions, also known as rules, that offer security by preventing unauthorized users from accessing particular resources and granting authorized users access. Additionally, ACLs can govern traffic flow, limit the information in routing updates, and determine which types of traffic are sent or denied. ACLs often sit ...
The term Aloha in computer network means hello. Aloha is a data-link layer multiple access protocols that describes how multiple terminals can access the medium without interfering or conflicting. Norman Abramson and his associates developed it in the 1970s at the University of Hawaii. Each node or station in ALOHA transmits a frame without attempting ...
