A Network Interface Card (NIC), also known as a network adapter or network card, is a hardware component that allows computers and other devices to connect to a network. NICs are responsible for the physical and data link layers of network communication and are crucial for enabling devices to send and receive data over a […]
A modem, short for “modulator-demodulator,” is a device used in telecommunications and computer networking to enable data to be transmitted over various communication channels. Modems are crucial for connecting computers and other digital devices to the internet, as well as for enabling communication between different types of networks. They serve as a bridge between digital […]
A hub is a basic network device that operates at the physical layer (Layer 1) of the OSI model. Its primary function is to connect multiple devices in a local area network (LAN) and transmit data from one device to all other devices connected to it. Hubs have largely been phased out in modern networking […]
An access point (AP) is a network device that allows Wi-Fi-enabled devices to connect to a wired network. It serves as a bridge between wireless clients, such as laptops, smartphones, and tablets, and the wired local area network (LAN). Access points are essential components in wireless networking and play a crucial role in extending network […]
