This document discusses various communication devices used for computer networks: - A Network Interface Card (NIC) and Wireless Network Interface Card (WNIC) allow computers to connect to wired and wireless networks respectively. - A modem converts digital signals from computers to analog for phone/cable lines, and vice versa, enabling data transmission over telephone or cable. - A hub and switch are used to connect multiple wired devices in a local area network (LAN), while a wireless access point performs a similar function wirelessly. - A router directs data traffic between networks, allowing multiple devices to share a single internet connection.
