The purpose of a modem is to facilitate communication between digital devices, such as computers or routers, and internet service providers (ISPs) over traditional communication mediums like telephone lines (DSL modem) or cable television lines (cable modem). Modems convert digital data from these devices into analog signals suitable for transmission over the respective communication lines. … Read more
The benefit of a hub in networking is its ability to serve as a central connecting point for multiple devices within a local area network (LAN). Hubs operate at the physical layer (Layer 1) of the OSI model and facilitate the transmission of data packets between devices by broadcasting incoming data packets to all connected … Read more

A point-to-point access point refers to a wireless networking device that establishes a direct wireless connection between two endpoints or locations. It operates in bridge mode to create a wireless link between two fixed points, enabling data transmission and communication over a specific distance without the need for additional networking infrastructure. Point-to-point access points are … Read more
The main purpose of a WAN (Wide Area Network) is to connect geographically dispersed locations or networks over a large geographical area. Unlike LANs (Local Area Networks) that cover smaller areas like a single building or campus, WANs facilitate communication and data exchange between remote sites, offices, or branches across cities, countries, or continents. This … Read more
