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
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
NTP measures time in seconds relative to January 1, 1900, in a 64-bit fixed-point format, with the integer part representing the number of seconds and the fractional part representing fractions of a second. NTP stands for Network Time Protocol, which synchronizes timekeeping among a set of distributed time servers and clients. It ensures accurate timekeeping … Read more
A firewall is used as a network security device to monitor and control incoming and outgoing traffic based on predetermined security rules. Its primary purpose is to act as a barrier between trusted internal networks and untrusted external networks (like the internet), inspecting data packets and deciding whether to allow or block them based on … Read more
HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are protocols used for transmitting data over the internet, but they differ significantly in terms of security: HTTP is the standard protocol used for transmitting and receiving hypertext messages on the World Wide Web. It operates over TCP/IP and typically uses port 80 for communication. … 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 is used to connect multiple devices within a local area network (LAN) and manage the traffic between them. It serves as a central hub that directs data packets between devices and ensures efficient communication across the network. Routers are essential for sharing a single internet connection among multiple devices, providing network security features, … Read more
A VLAN IP (Virtual Local Area Network IP) refers to an IP address assigned to a virtual interface on a VLAN. VLANs are used to logically segment a physical network into multiple virtual networks, each with its own set of devices and network policies. A VLAN IP is typically configured on a VLAN interface of … Read more
A WiFi repeater is a device used to extend the coverage area of a wireless network. It receives the existing WiFi signal from a router, amplifies it, and then rebroadcasts it to create a second network. This extended network allows devices farther from the router to connect to the internet more reliably. The purpose of … Read more
