Ethernet refers to a networking technology used for local area networks (LANs) to connect devices within a confined area such as an office building, school campus, or home. It defines how data is transmitted over physical cables or wireless connections, specifying protocols for data encoding, framing, collision detection, and media access control. Ethernet and the … Read more

Switching in a computer network refers to the process of forwarding data packets between devices within a local area network (LAN). It involves a network switch, which is a hardware device that operates at the data link layer (Layer 2) or network layer (Layer 3) of the OSI model. Switches use MAC addresses or IP … Read more

A switch is used in computer networks to connect multiple devices within a local area network (LAN) and facilitate communication between them. Its primary purpose is to manage and direct data traffic by forwarding data packets to their intended destinations based on the MAC addresses of the devices connected to the switch. The purpose of … Read more

The functionality of a service mesh revolves around managing and controlling communication between microservices within a distributed application. Service mesh provides essential capabilities such as service discovery, load balancing, secure communication, and observability. It abstracts network communication complexities from application code, allowing developers to focus on business logic while delegating networking concerns to the service … Read more

Three main functions of a router include: Packet Forwarding: Routers forward data packets between different computer networks. They examine the destination IP address of each packet and determine the best path for it to reach its destination, ensuring efficient data transmission across interconnected networks. Routing: Routers use routing protocols to communicate with other routers and … Read more

A router and modem serve different roles in a network setup. A modem is a device that connects your network to your internet service provider’s network. It converts digital data from your devices into signals that can travel over telephone lines, cable systems, or fiber optic networks. A router, on the other hand, is a … Read more

The use of a proxy URL serves to redirect requests from a client to another server on behalf of the client. This intermediary server acts as a gateway between the client and the internet, allowing the client to access resources indirectly through the proxy server. Proxy URLs are commonly employed to enhance privacy, bypass content … Read more

The basics of a firewall involve its role as a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Firewalls act as barriers between trusted internal networks and untrusted external networks (like the internet), inspecting packets of data and determining whether to allow or block them based … Read more

HTTP (Hypertext Transfer Protocol) and WWW (World Wide Web) are fundamental components of internet communication: HTTP is a protocol used for transmitting and receiving hypertext messages on the internet. It defines how messages are formatted and transmitted, specifying rules for web browsers and servers to exchange information. HTTP enables the retrieval of web pages, images, … Read more
