CSMA/CD with the Binary Exponential Backoff
Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is a network protocol for carrier transmission that operates in the Medium Access Control (MAC) layer. It senses or listens whether the shared channel for transmission is busy or not, and defers transmissions until the channel is free. When more than one station sends their frames simultaneously, collision occurs. Binary Exponential Backoff is a collision resolution mechanism which is commonly used to schedule retransmissions after collisions in Ethernet. The waiting time that a station waits before attempting retransmission of the frame is called backoff time. How CSMA/CD Works ...
Read MoreTransparency of RPC in Distributed Networks
In distributed networks, communication between different nodes is essential for achieving desired functionality. Remote Procedure Call (RPC) enables this communication by allowing programs to execute procedures on remote servers as if they were local. However, the success of distributed networks often depends on RPC transparency. RPC can be defined as a function call used by one program to request services from another program, where these programs may be located on different systems across the network. RPC Transparency in Distributed Networks Client Node Application Program A ...
Read MoreWhat is Wireless Local Area Network (WLAN)?
WLAN stands for Wireless Local Area Network. WLAN is a wireless network that allows devices to associate and communicate wirelessly within a localized area such as a home, office, or campus. Just like a traditional wired LAN where devices transmit over Ethernet cables, devices using WLAN transmit through WiFi radio waves. Mobile users can connect to a WLAN through wireless adapters built into their devices. The IEEE 802.11 group of standards defines the technologies and protocols for wireless LANs, including common WiFi standards like 802.11n, 802.11ac, and 802.11ax (WiFi 6). WLAN Architecture ...
Read MoreLooking Up: Mastering the Nslookup Command in Linux with Examples
The nslookup command is a powerful network administration tool used in Linux for querying Domain Name System (DNS) records efficiently. Whether you are a novice or a professional, this command helps you troubleshoot and test DNS by mapping domain names to IP addresses, as well as providing valuable information on various resource records such as MX and NS. In this article, we will explore the basics of nslookup command usage through practical examples along with advanced techniques that enhance its capabilities for network troubleshooting and DNS administration. Basic Usage of Nslookup Command The basic usage of the ...
Read MoreWhat is MMS (Multimedia Messaging Service)?
MMS (Multimedia Messaging Service) is a standard method of sending multimedia messages to and from a mobile phone via a mobile network. Users and providers might refer to these messages as picture messages or multimedia messages. MMS extends the capabilities of SMS (Short Message Service) by allowing the exchange of messages containing multimedia content beyond the 160-character text limit. Unlike text-only SMS, MMS can deliver various media including images, up to 40 seconds of video, multi-image slideshows, and audio files. The first MMS-enabled phones were introduced in 2002 alongside early GSM networks. The Sony Ericsson T68i is widely ...
Read MoreType-C Port in Computer Network
The Type-C Port (also known as USB-C) is a universal connector standard that combines power delivery and high-speed data transfer capabilities. Unlike previous USB standards, USB-C features a reversible design and can deliver up to 100 watts of power, making it suitable for charging everything from smartphones to laptops. USB-C has emerged as the industry standard, gradually replacing older connectors like USB-A, USB-B, and even specialized ports like Thunderbolt and DisplayPort. Its versatility lies in supporting multiple protocols through a single, compact connector. USB-C Port Evolution ...
Read MoreDifference between OneDrive and HCL Connections
Cloud services and enterprise collaboration platforms offer different capabilities for organizations and individuals. While some focus on file storage and synchronization, others emphasize team collaboration and social networking within organizations. In this article, we explore the key differences between OneDrive, Microsoft's cloud storage service, and HCL Connections, an enterprise social collaboration platform. OneDrive Microsoft OneDrive is a file hosting and synchronization service launched in August 2007 as part of Microsoft's web-based Office suite. OneDrive enables users to store files and personal data in the cloud while keeping files synchronized across multiple devices including Android, iOS, Windows, and macOS ...
Read MoreEthernet Throughput
Throughput of a system refers to the rate of processing of a task thereby generating results. Ethernet is a set of technologies primarily used in LANs, whose primary data units are frames. The throughput of Ethernet is measured by the rate of successful delivery of frames over a communication channel. There are several methods for representing Ethernet throughput. The least ambiguous among them is calculation of channel efficiency. Channel efficiency is the percentage of the net bit rate (in bits per second) of a channel that is actually communicated. Suppose that an Ethernet connection has a speed of 100 ...
Read MoreTypes Of Memory On A Cisco Device
Cisco networking devices such as routers and switches utilize different types of memory to perform their various functions. Each memory type serves a specific purpose in the device's operation, from storing the operating system to maintaining configuration files and routing tables. Understanding these memory types is essential for network administrators working with Cisco equipment. Types of Memory on Cisco Devices Cisco devices use four primary types of memory: RAM (DRAM) − Volatile memory for active operations Flash Memory − Non-volatile storage for the operating system ROM − Read-only memory containing boot programs NVRAM − Non-volatile storage ...
