(a) Allows the device to connect to a network / communicate with the network.
(b) MAC Address / Media Access Control Address.
(a) Switch Operation:
(b) Hub Performance:
(a) WAP: Converts wireless signals to wired (1), allows wireless devices to connect to LAN (1).
(b) Router: Connects LAN to Internet/WAN (1), routes packets to destination (1).
(c) Difference: Switch connects devices on ONE network (LAN) vs Router connects DIFFERENT networks (LAN to WAN) (1). Switch uses MAC addresses vs Router uses IP addresses (1).
Switch: Connects computers to form LAN (1), directs data only to correct user (efficient) (1).
Router: Connects LAN to Internet/ISP (1), assigns IP addresses / routes external traffic (1).
Why Both: Switch handles internal traffic; Router handles external traffic. They perform different roles. (1)
