Fast Ethernet (802.3u)
Fast Ethernet (IEEE 802.3u) is a variation of Ethernet standards that carries data traffic at 100 Mbps in local area networks. It was launched as the IEEE 802.3u standard in 1995 and remained the fastest network technology until the introduction of Gigabit Ethernet. Fast Ethernet is commonly named 100BASE-X, where 100 represents the maximum throughput (100 Mbps), BASE denotes the use of baseband transmission, and X indicates the type of medium used (TX or FX). Fast Ethernet Evolution 10BASE-T 10 Mbps 100BASE-TX ...
Read MoreWhat is Multistation access unit (MSAU)?
A multistation access unit (MSAU), also called a media access unit (MAU), is a central device that acts as Ethernet transceivers in local area networks. It is used to connect network stations or nodes in LANs and operates according to the principle of token ring. The multiple stations are connected in a star topology physically but are internally wired into a logical ring. MSAU - Physical Star, Logical Ring MSAU 1 ...
Read MoreFrame bursting in Computer Network
Frame bursting is a transmission technique used at the data link layer of the OSI model to increase the rate of transmission of data frames. It can be effectively deployed in Gigabit Ethernet networks to increase network throughput and is specified in the IEEE 802.11e QoS specification. By this technique, a sender can transmit a series of frames in succession without surrendering control of the transmission medium. A set of smaller frames may be concatenated to form a large frame that is transmitted at one go, reducing overhead and improving efficiency. How Frame Bursting Works Standard Transmission ...
Read MoreHow Can I Make Money with Blockchain Technology?
Are you curious about the financial opportunities in blockchain technology? This decentralized system offers multiple avenues for generating income beyond traditional cryptocurrency trading. While Bitcoin was the first application of blockchain, the technology has evolved to create diverse monetization opportunities across various industries. Blockchain represents one of the most transformative technologies since the internet, enabling new business models and reshaping how we conduct transactions, verify data, and build trust in digital systems. Here are practical ways to capitalize on blockchain's growing adoption. Blockchain Software Development Becoming a blockchain developer offers the highest earning potential in this field. ...
Read MoreRetrospective on Ethernet
Ethernet is a set of technologies and protocols that are used primarily in LANs. It was first standardized in the 1980s as the IEEE 802.3 standard and has evolved continuously ever since. Few networking technologies have demonstrated such remarkable consistency and longevity in their usability and adoption. Since its inception, Ethernet has undergone significant transformations while maintaining backward compatibility, making it the dominant LAN technology worldwide. Its evolution reflects the growing demands for higher bandwidth and improved network performance. Advantages of Ethernet Simple and reliable − Ethernet uses straightforward protocols and proven technology that works ...
Read MoreDistributed Coordination Function (DCF)
Distributed Coordination Function (DCF) is a mandatory medium access control technique used in IEEE 802.11 wireless networks (Wi-Fi) to prevent frame collisions. DCF implements Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) to coordinate channel access among multiple wireless stations. Unlike wired networks that can detect collisions, wireless networks cannot easily detect when two stations transmit simultaneously due to the hidden terminal problem. DCF solves this by using collision avoidance mechanisms rather than collision detection. How DCF Works The DCF process follows these key steps: Random Backoff − When a station has data to ...
Read MoreDifference between Connection-oriented and Connection-less Services
Connection-oriented and Connection-less Services are two fundamental approaches used to establish communication between devices in a network. Understanding their differences is crucial for network design and protocol selection. Connection-oriented Services A connection-oriented service establishes a dedicated communication path between sender and receiver before data transmission begins. It is modeled after the telephone system where you dial a number, establish a connection, communicate, and then hang up. Connection-oriented services operate through three phases: connection establishment, data transfer, and connection termination. Data packets are delivered to the receiver in the same order they were sent by the sender. ...
Read MoreDifference between Hub and Switch
A hub and a switch are both networking devices used to connect multiple devices, but they operate fundamentally differently. Hubs are basic network devices that operate at the Physical Layer and broadcast data to all connected devices. Switches function at the Data Link Layer and intelligently forward data only to the intended recipient using MAC addresses. Understanding the differences between hubs and switches is crucial for network design, as switches have largely replaced hubs in modern networks due to their superior performance and security features. What is a Hub? A hub is a basic networking device that ...
Read MoreDifference between LAN and VLAN
A Local Area Network (LAN) is a physical network that connects devices within a limited geographical area, while a Virtual LAN (VLAN) is a logical network that groups devices across potentially multiple physical networks. VLANs enhance network performance, security, and management by creating broadcast domains independent of physical location. Understanding the distinction between these two networking concepts is essential for network design and administration. What is LAN? A Local Area Network (LAN) is a network that spans a limited geographical area, typically within a single building or campus. It connects computers, servers, printers, and other networked devices ...
Read MoreDifference between WiFi and BlueTooth
Both WiFi and Bluetooth are wireless technologies that are widely used to send and receive data wirelessly using radio signals. WiFi is designed for high-speed Internet access that connects nearby devices with each other and shares Internet connectivity via hotspots, whereas Bluetooth is optimized for connecting devices in short range with minimal power consumption. This article explores the key features of WiFi and Bluetooth technologies and examines their fundamental differences in terms of range, speed, power consumption, and use cases. What is WiFi? WiFi stands for Wireless Fidelity. It defines any network based on the 802.11 standards ...
