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 ...
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 ...
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. ...
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 ...
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, ...
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 ...
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 ...
