Introduction OSI model or Open Systems Interconnection model serves as a framework that explains the process of information transfer, i.e., from one computer’s software application to another computer through a medium. It was created by the International Organization for Standardization (ISO) in 1984. It is now widely acknowledged as an architecture model for inter-computer communication. […]

Introduction The Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables devices to obtain IP addresses and other network configuration details from a server. DHCP simplifies IP addresses as well as reduces the need for configuration. However, it also introduces security risks, such as DHCP spoofing and DHCP starvation. To safeguard the network […]

Introduction A MAC address, also known as a Media Access Control address, is an identifier given to a network interface controller (NIC) in a device that communicates through a network. MAC addresses have uses, including filtering, routing, security, and identifying devices. In this blog, we will explain the MAC address and its purpose. We will […]

Introduction The Internet is a web of interconnected devices that communicate using protocols. One such protocol is the Internet Control Message Protocol (ICMP), which helps network devices diagnose communication issues. ICMP protocol plays a significant role in determining whether the data is reaching its intended destination on time or not. Typically, routers and other network […]

Introduction One of the most important concepts in routing is administrative distance (AD). AD is a metric that determines the reliability or trustworthiness of a routing source. With the help of AD value, routers can easily choose the best route among multiple routes to the same destination. In this blog, we will explain the concept […]

Introduction If you want to control a server or machine that is physically inaccessible, you need to communicate with it remotely. However, not all remote strategies are stable and secure. For example, older protocols like Telnet or rlogin ship your commands and passwords in simple text, which can effortlessly be intercepted by means of hackers […]

Introduction The Internet is a vast network where a number of devices are connected with the help of IP or Internet Protocol. IP addresses are numerical identifiers that are used to uniquely identify each device that is available inside the network. As we all have seen, the internet is growing exponentially day by day, resulting […]

Introduction In a network, routers communicate with one another via different routing protocols available. Routing protocols help routers in order to choose the best path to a destination and also maintain the routing table. There are several types of routing protocols each with different functionalities, some of which are path vector, link state, and distance […]

Introduction Routing and routed protocols are two critical principles in computer networking that confuse many students. Both are associated with the network layer of the OSI model, which is responsible for offering logical addressing and routing packets across different networks. Both have specific features and traits. In this blog, we will explain routing protocol vs […]
