Network Components and Protocols

Front

Network Components: Hubs

Back

A hub copies all packets of data to all devices on the network. Only the device that requires the data will recognize and receive it.

Front

Network Components: Switches

Back

A switch analyzes each packet of data and sends it to the computer for which it was intended.

Front

Network Components: Routers/Wireless Routers

Back

A router stores the addresses of computers on the network and transfers data between devices. It usually connects at least two different networks.

Front

Network Components: Gateways

Back

A gateway joins together two networks that use different base protocols, e.g., it links a LAN to a WAN.

Front

Network Component: Bridge

Back

A bridge joins together two networks that use the same base protocols, e.g., it links a LAN to a LAN.

Front

Network Components: Wireless Access Points

Back

A device that allows other Wi-Fi devices to connect to a network.

Front

Network components: NIC card/wireless NIC (Network Interface Card)

Back

Allows devices to access a network. A wireless NIC allows devices to access a network wirelessly.

Front

Protocols and Standards: Definition

Back

A protocol is a set of rules defining how networked devices communicate. Protocols are standardized so that all devices have a set method of communicating with each other, regardless of the manufacturer.

Front

Protocols and Standards: Importance

Back

Network protocols are vital for allowing communication between computers on networks. Without shared common protocols, computers would not be able to communicate.

Front

Types of Protocols: Ethernet

Back

Ethernet is a wired (cable connection) protocol.
