Difference between Baseband and Broadband Transmission
Data transmission has been crucial in the age of digital communication. Either digital or analogue data can be transmitted over a communication medium to one or more devices, depending on the interfaces in use. There are two important types of data transmission − Baseband and Broadband. Understanding the differences between these transmission methods is essential for network design and choosing the appropriate technology for specific communication requirements. What is Baseband Transmission? Baseband transmission is a technology where a single digital signal occupies the entire bandwidth of the communication channel. The signal is transmitted in its original frequency ...
Read MoreVegas A (Modified TCP-Vegas)
TCP Vegas A (Modified TCP-Vegas) is an adaptive congestion avoidance algorithm that detects network congestion based on Round Trip Time (RTT) measurements rather than packet loss. The "A" stands for "Adaptive, " emphasizing its ability to dynamically adjust to network conditions. Developed by Larry Peterson and Lawrence Brakmo in 1994, TCP Vegas focuses on preventing congestion proactively by monitoring packet delays. Unlike traditional TCP variants that react to packet loss, TCP Vegas maintains smaller congestion windows during transmission to achieve better throughput with fewer packet losses. It relies on accurate calculation of the Base RTT to distinguish between network ...
Read MoreAdvantages and Disadvantages of Static IP
In computer networking, IP addresses serve as unique identifiers that enable devices to communicate within a network. When configuring network infrastructure, administrators must choose between static and dynamic IP addressing schemes. A static IP address is a fixed address manually assigned to a device that remains constant over time, unlike dynamic addresses that change automatically. Static IP addressing offers specific benefits for certain network scenarios, particularly for servers and enterprise environments. However, it also presents challenges in terms of management overhead and security considerations that organizations must carefully evaluate. Static vs Dynamic IP Address ...
Read MoreDifference between Antivirus and Antimalware
When it comes to computer security, two terms that are frequently used and often confused are antivirus and antimalware. While both are designed to protect computers from malicious software, they have distinct differences in scope, detection methods, and functionality. Antivirus Software Antivirus software is specifically designed to detect, prevent, and remove viruses — a particular type of malware that can replicate itself and spread to other computers. Antivirus programs use a database of known virus signatures to identify and eliminate threats from a computer system. These signatures are digital fingerprints of known viruses that have been analyzed ...
Read MoreDifference between Router and Gateway
Both routers and gateways are network connecting devices that serve different purposes in network infrastructure. Routers work at the network layer and are responsible for finding the shortest path for data packets between networks. Gateways function as nodes that provide access points and protocol translation between different network types. Understanding the distinction between these devices is essential for network design and troubleshooting. What is a Router? A router is a network device that determines the optimal path for data packets to reach their destination. Its primary function is to connect multiple networks and forward traffic between them ...
Read MoreWhat is the difference between the keylogger and the Remote Access Trojans?
Let us begin by understanding the key differences between keyloggers and Remote Access Trojans (RATs), two distinct types of malicious software with different capabilities and objectives. Keylogger A keylogger is a technology that tracks and records consecutive keystrokes on a keyboard. Because sensitive data including usernames and passwords are often entered through keyboards, keyloggers can be extremely dangerous security threats. There are several types of keyloggers based on different monitoring methods: Software keyloggers − Can be built into rootkits or other less detectable forms and can infiltrate computers through various methods Hardware ...
Read MoreDifference between Batch Processing and Stream Processing
Computer systems have been handling data since decades, but the volume and speed of handling has become phenomenal in the last few years. Data processing means "the collection and manipulation of items of data to produce meaningful information", has been evolving in terms of speed, efficiency, and leveraging the computing resources. In this article, we will see two important techniques of data processing in the field of computation − Batch processing and Stream processing. We will elaborate them in detail and see how they are different. What is Batch Processing? Batch processing is a technique of processing ...
Read MoreWhat is dynamic frequency selection (DFS)?
Dynamic Frequency Selection (DFS) is a technique used in IEEE 802.11 wireless networks or WiFi that permits devices to dynamically switch the operating frequency of transmission in order to avoid interference with other devices. How DFS Works DFS operates by continuously monitoring the radio spectrum for radar signals. When a wireless device detects radar activity on its current channel, it must immediately cease transmission and switch to an alternative frequency within a specified timeframe to prevent interference. DFS Frequency Switching Process WiFi AP ...
Read MoreMastering the Fundamentals: Understanding Packet Switching and Delays in Computer Networks
Packet switching is a fundamental network communication method that breaks data into smaller units called packets for efficient transmission across networks. Instead of sending large files as single units, packet switching divides data into manageable pieces, each containing part of the original data plus routing information like source and destination addresses. When you send a message or file, your device divides it into packets based on network protocols. These packets travel independently through various network nodes and routers, potentially taking different paths to reach their destination. Upon arrival, packets are reassembled in the correct sequence to recreate the original ...
Read MoreWhat is Session Layer in the Computer Network?
The Session Layer is the fifth layer in the OSI model and one of the upper layers that provide user-oriented services. It sits between the Presentation Layer and Transport Layer, managing communication sessions between applications on different devices. The session layer provides a defined set of services to the presentation layer and controls the structure and interaction between application programs. It synchronizes communication, manages the direction of information flow, and handles session establishment, maintenance, and termination. The service definition and protocol specifications are defined in ISO 8326 and ISO 8327. Session Layer in OSI ...
