A peer-to-peer network is a decentralized network architecture where individual nodes (computers or devices) communicate directly with each other without relying on a central server. Each node in the network can act as both a client and a server, sharing resources such as files, computing power, or services with other nodes in the network. This … Read more
The WAN (Wide Area Network) connection method refers to how devices and networks connect and communicate over large geographical distances. It involves using various technologies and protocols to establish reliable and secure communication links between different locations. WAN connection methods include leased lines, such as T1/E1 lines, which provide dedicated point-to-point connections with guaranteed bandwidth. … Read more
Cloud storage refers to a service model where data is stored, managed, and maintained remotely on servers accessible over the internet. It allows users to store and retrieve data from anywhere with an internet connection, eliminating the need for physical storage devices like hard drives or flash drives. Cloud storage providers typically offer scalable storage … Read more
A LAN (Local Area Network) network works by connecting computers and devices within a limited geographical area, such as an office building, school campus, or home, using Ethernet cables or wireless technologies like Wi-Fi.

A port in networking refers to a communication endpoint or a numeric identifier used by network protocols to distinguish between different services or processes on a single device. Ports enable multiple applications or services running on a device to concurrently send and receive data over a network. Each port is associated with a specific protocol … Read more
UDP (User Datagram Protocol) is a connectionless and lightweight transport protocol in computer networking. It operates at the transport layer of the TCP/IP model and provides a way to send datagrams, or packets of data, across a network without establishing a dedicated connection. UDP is known for its simplicity and low overhead, making it suitable … Read more
