OSPF (Open Shortest Path First) plays a crucial role in computer networks by dynamically calculating the shortest path for routing IP packets based on various metrics. Its primary role is to facilitate efficient and scalable routing within autonomous systems (AS). OSPF achieves this by maintaining a topology database of the network and calculating the best … Read more
A server on the internet refers to a computer or software system that provides services or resources to other computers or clients over the internet. These servers are accessible globally and respond to requests from users or other systems connected to the internet. Examples include web servers that host websites, email servers that handle email … Read more
The BGP port refers to port 179, which is the standard port number used by the Border Gateway Protocol (BGP) for communication between BGP-speaking routers. This port is designated for establishing TCP connections between BGP routers to exchange routing and reachability information across different autonomous systems (ASes) on the Internet. By using port 179, BGP … Read more
An SSL certificate is used to establish a secure, encrypted connection between a user’s web browser and a web server. It ensures that data exchanged between the two remains private and integral. This is crucial for protecting sensitive information such as login credentials, credit card details, and personal data. We need SSL certificates primarily for … Read more
A server is a computer or software system that provides services, resources, or functionalities to other computers or clients within a network. It operates by receiving requests from client devices and responding with the requested data, application functionality, or access to resources such as files or databases. Servers are essential for enabling communication, data storage, … Read more
The benefit of using BGP (Border Gateway Protocol) lies in its ability to manage large-scale networks with complex routing requirements effectively. BGP is designed for interdomain routing, allowing autonomous systems (ASes) to exchange routing information and make informed routing decisions based on policies, network performance, and other criteria. Key benefits include: Policy-Based Routing: BGP enables … Read more
The purpose of WPA3 (Wi-Fi Protected Access 3) is to enhance the security of wireless networks, addressing vulnerabilities and weaknesses found in its predecessor, WPA2. WPA3 aims to provide stronger encryption, more robust authentication mechanisms, and improved protection against brute-force attacks and other security threats commonly targeting Wi-Fi networks. WPA3 is used to secure Wi-Fi … Read more
The basics of fiber optics involve the transmission of light through thin, flexible strands of glass or plastic fibers. These fibers are designed to guide light through total internal reflection, where light entering the core of the fiber at a shallow angle reflects off the core-cladding interface and continues along the fiber’s length. This principle … Read more
Fiber optics are used for various purposes, primarily in telecommunications and networking to transmit data signals over long distances at high speeds. They are also employed in medical imaging, industrial sensing, and automotive applications where reliable and high-bandwidth communication is essential. The purpose of using fiber optics lies in its ability to provide high-speed, reliable, … Read more
The three types of NFS (Network File System) primarily refer to different versions or protocols used for file sharing over a network: NFSv2 (Network File System version 2): This was an early version of NFS developed by Sun Microsystems. NFSv2 used UDP (User Datagram Protocol) for data transmission and lacked features such as strong security … Read more
