What is an ARC NET in the Computer Network?
ARC NET (Attached Resources Computing Network) is a local area network topology that uses coaxial cables and token passing protocol for data transmission. Developed by Datapoint Corporation in the late 1970s, it was one of the earliest commercial networking technologies, predating both Ethernet and IBM Token Ring. ARC NET uses a 93-ohm RG-62 A/U coaxial cable, which is incompatible with thin Ethernet's 50-ohm cables despite their similar appearance. The network operates at 2.5 Mbps using analog signaling and can support up to 255 nodes (not 55 as often misunderstood) with proper configuration. ARC NET ...
Read MoreWhat is the difference between an IP Camera and CCTV Camera?
Let us begin by understanding what an IP Camera is and how it differs from traditional CCTV cameras. IP Camera An IP camera is a network digital camera that uses the Internet Protocol (IP) and has its own unique IP address. IP cameras are commonly used in modern video surveillance systems for enhanced security monitoring. An IP camera uses an Ethernet cable to send digital signals over a network. This type of camera can be easily networked and can transmit signals to a network video recorder (NVR) located on either a local or remote network. IP ...
Read MoreWhat is the difference between Internet, Intranet and Extranet?
The Internet, Intranet, and Extranet are three distinct types of networks that serve different purposes and user groups. Understanding their differences is crucial for grasping modern network architecture and business communications. Internet The Internet is the world's largest public network that connects millions of computers, servers, and devices globally. It is a vast collection of interconnected networks including public, private, government, academic, and business networks linked through various technologies such as fiber optic cables, wireless connections, and satellite links. The Internet operates as a global network infrastructure using physical cables like copper telephone wires, fiber optic cables, ...
Read MoreWhat is the difference Between Trademark and Domain Name?
Understanding the relationship between trademarks and domain names is crucial in today's digital business landscape, as both serve as important identifiers but operate under different legal and technical frameworks. Trademark A trademark is a distinctive sign, symbol, word, phrase, logo, or design that identifies and distinguishes the goods or services of one company from those of others in the marketplace. Trademarks serve as brand identifiers that help consumers recognize the source of products or services. When a trademark relates specifically to services rather than goods, it is technically called a service mark, though the term "trademark" is ...
Read MoreWhat is the difference between Laptop and Netbook?
Understanding the differences between laptops and netbooks is essential when choosing the right portable computing device for your needs. While both offer mobility, they serve different purposes and target different user requirements. Laptop A laptop is a full-featured portable computer designed for flexibility and performance. It typically weighs between 4-8 pounds (2-4 kilograms) depending on display size, hardware specifications, and build quality. Laptops are also commonly referred to as notebooks. Modern laptops can function as complete desktop replacements through docking stations. These stations allow seamless connection of peripheral devices including printers, scanners, and external drives. Users can ...
Read MoreWhat is Fully-Interconnected Network Topology?
A Fully-Interconnected Network Topology, also known as a mesh topology, is a network design where every node is connected to every other node through dedicated point-to-point links. This creates a complete network where each device has direct communication paths to all other devices without requiring intermediate nodes. In this topology, each computer has its own control and decision-making power for communication priorities. The network provides high reliability since the failure of any single transmission line only affects communication between those two specific nodes, while all other connections remain operational. Fully-Interconnected Network (5 Nodes) ...
Read MoreWhat is the difference between CAN and MAN?
A Campus Area Network (CAN) and Metropolitan Area Network (MAN) are both intermediate network types that bridge the gap between Local Area Networks (LAN) and Wide Area Networks (WAN), but they serve different purposes and cover different geographical areas. Campus Area Network (CAN) A Campus Area Network (CAN) is a network that interconnects multiple LANs within a limited geographical area, typically spanning a university campus, corporate campus, or military base. CAN uses the same technology and hardware across multiple buildings within the same organization or association. CANs are cost-effective and simple to implement within a few kilometers ...
Read MoreWhat is the difference between Checksum and CRC?
Both Checksum and Cyclic Redundancy Check (CRC) are error detection techniques used to verify data integrity during transmission or storage. While they serve the same fundamental purpose, they differ significantly in their complexity, accuracy, and implementation methods. What is Checksum? A checksum is a simple error detection method that generates a fixed-size value from a block of data. The most basic checksum algorithm adds all bytes in a data block and uses the result as a verification code. Common checksum algorithms include: Simple sum checksum − Adds all bytes in the data Fletcher's checksum − Uses ...
Read MoreWhat is MultiDrop Network Topology in Computer Network?
A MultiDrop Network Topology, also known as a broadcasting network, is a network configuration where multiple nodes share a single communication line or cable. Unlike a fully interconnected network that requires individual cables between all nodes, this topology uses one shared medium for all network communication. MultiDrop Network Topology A B C D Single Shared Communication Line Message ...
Read MoreWhat is Gigabit Ethernet?
Gigabit Ethernet is a high-speed variant of Ethernet technology that transmits data at 1 Gbps (1, 000 Mbps) in local area networks (LANs). It serves as a backbone for enterprise networks, providing significantly faster data transmission than earlier Ethernet standards. Gigabit Ethernet extends the proven 802.3 Ethernet family, which includes 10 Mbps and 100 Mbps variants. It delivers ten times the bandwidth of Fast Ethernet while maintaining full backward compatibility with existing Ethernet infrastructure and devices. How Gigabit Ethernet Works Gigabit Ethernet uses different physical media depending on the transmission distance. For long-distance connections, it typically employs ...
