What is Campus Area Network (CAN)?
A Campus Area Network (CAN) is a computer network that interconnects multiple buildings within a limited geographical area such as a university campus, corporate complex, or industrial site. CAN is larger than a Local Area Network (LAN) but smaller than a Metropolitan Area Network (MAN) or Wide Area Network (WAN). The primary purpose of CAN is to provide high-speed connectivity and resource sharing between different departments, buildings, and facilities within an organization's premises. For example, a university CAN connects academic buildings, libraries, dormitories, and administrative offices, enabling seamless communication and data sharing across the entire campus. ...
Read MoreWhat are the differences between Physical and Logical Topology?
Network topology refers to the arrangement and interconnection of network devices. Understanding network topology is crucial for network design, troubleshooting, and optimization. There are two fundamental ways to view network topology: physical topology and logical topology. Physical topology describes the actual physical layout and connections of network devices, while logical topology describes how data flows through the network regardless of the physical connections. Physical vs Logical Topology Physical Topology ...
Read MoreDifference between a Managed and an Unmanaged Switch
A network switch serves as the central hub connecting devices in a network, making it essential to choose the right type for your infrastructure. Switches vary in size and port count, typically offering up to 48 ports, with managed and unmanaged switches being the two primary categories. Managed vs Unmanaged Switch Architecture Managed Switch • Remote Configuration • VLAN Support • Advanced Security Unmanaged Switch • Plug-and-Play • Fixed Configuration • Lower Cost ...
Read MoreCATA protocol in Computer Network
Computer networks require efficient protocols to manage address assignments and prevent conflicts as they grow in complexity. The Common Address Table Algorithm (CATA) protocol is designed to centralize IP address management and provide redundancy mechanisms for network stability. CATA builds upon existing address resolution protocols to create a distributed yet coordinated approach to IP address assignment, reducing conflicts and improving network reliability through its redundancy features. How CATA Protocol Works The CATA protocol operates through a distributed address table system where multiple nodes maintain synchronized copies of address assignments. When a device requests an IP address, the ...
Read MoreChallenge Handshake Authentication Protocol (CHAP)
Challenge Handshake Authentication Protocol (CHAP) is a widely used authentication method that provides an added layer of security to network connections. This protocol is commonly used in Point-to-Point Protocol (PPP) connections, such as those used for dial-up internet access or virtual private network (VPN) connections. The basic principle of CHAP is that it challenges the connecting client to prove their identity by providing a specific response to a unique challenge. This challenge-response mechanism is designed to prevent unauthorized access and protect against replay attacks. How CHAP Works CHAP uses a three-step process to authenticate a client: ...
Read MoreCharacteristics of Virtualization
Virtualization is a technology that allows multiple virtual machines to run on a single physical machine. It has become an essential component of modern IT infrastructure, enabling efficient resource utilization and flexible computing environments. In this article, we will explore the key characteristics of virtualization and their practical applications. Virtualization Overview Physical Host Machine VM 1 OS + Apps VM 2 OS + Apps VM 3 OS + Apps ...
Read MoreCisco ASA Redistribution example
Redistribution is a process of sharing routing information between different routing protocols. In Cisco ASA, redistribution enables integration of various routing domains by allowing different protocols to exchange routing information. This improves overall network connectivity and simplifies network management when multiple routing protocols coexist. The most common routing protocols supported on Cisco ASA include RIP (Routing Information Protocol), OSPF (Open Shortest Path First), and EIGRP (Enhanced Interior Gateway Routing Protocol). Cisco ASA Redistribution Process OSPF Domain A Cisco ASA Redistribution ...
Read MoreCisco Router basic commands
Cisco routers are a popular choice for network administrators due to their robustness and reliability. They are used in a wide range of environments, from small home networks to large enterprise networks. To effectively manage a Cisco router, it is essential to have a good understanding of the basic commands that are used to configure and troubleshoot the device. Accessing the Cisco Router The first step in configuring a Cisco router is to access the device. This can be done using a variety of methods, including Telnet, SSH, and the console port. The most common method is to ...
Read MoreCisco Switch Configuration basic commands
Cisco switches are widely used in enterprise networks for their reliability and advanced features. However, configuring these switches can be a daunting task for those new to networking. In this article, we will cover some basic commands that are commonly used when configuring Cisco switches. Accessing the Switch The first step in configuring a Cisco switch is to access the switch's command-line interface (CLI). This can be done through a console cable or through a Telnet or SSH connection. Console Access: Connect a console cable to the switch and a computer's serial port. Open terminal emulator software ...
Read MoreClasses of Routing Protocols
Routing protocols are essential mechanisms that enable network devices to determine the best paths for data transmission across interconnected networks. These protocols ensure efficient and reliable data delivery by making intelligent routing decisions based on various network metrics and topologies. Understanding the different classes of routing protocols helps network administrators choose the most appropriate solution for their specific network requirements, size, and complexity. Classes of Routing Protocols Distance Vector Link State Hybrid ...
