Computer networking components

Hub

  • Hardware device that enables multiple connections to a computer

  • Broadcasts all data across each connection (no routing tables)

  • An example is a USB hub. The hub allows several USB devices to connect to a single node. The USB hub simply connects to the USB port on a computer.

  • The price of a simple USB hub is between $10 - $20


Switch

Switch

  • Hardware device that can connect multiple nodes together within a LAN. A switch can be used to setup a home network between devices.

  • Operates at layer two of the OSI model using routing tables. Interprets source and destination devices and forwards data to the intended device.

  • Consumer switches are between $25 - $30


Router

Router

  • Hardware device that connects multiple networks together such as local area networks (LAN) and wide area networks (WAN).

  • The router operates at layer 3 of the OSI model. It can be used in a home network (wired or wireless) to connect to a WAN such as the Internet.

  • The cost of consumer model router is between $80 - $200


Bridge

Bridge

  • Hardware device that connects multiple notes and reduces the amount of traffic on a LAN.

  • Operates at layer 2 of the OSI model. Inspects data frames to determine source and destination, then forwards to the intended device if no errors are detected. A bridge can be used in a home network (wired or wireless).

  • The cost of a consumer model is between $60 - $250


Gateway

Gateway

  • Hardware and/or software that join together two networks of different protocols.

  • A network gateway operates at any level of the OSI model and can typically include a firewall. It uses Ethernet MAC addresses for routing. In example, a broadband router would be used as a gateway in a home network.

  • A consumer price for a gateway would be between $90 - $150.


Firewall

Firewall

  • Hardware and/or software that prevents hacks and viruses from reaching a computer over the internet. Firewalls can be placed in each node, as well as, in the router to protect a network.

  • A firewall inspects data packets to determine if they should be allowed in the network or node based on a set of rules and protocols. It can perform basic routing functions.

  • An average price of a firewall software is between $35 - $70.


Wireless ap

Wireless AP

  • Hardware device with a network adapter and radio transmitter that functions as an access point to transmit and receive WLAN radio signals. Can be a stand alone device or part of a router.

  • Typically connects to a wired network and broadcasts WIFI signals to other devices. Wireless AP’s can be used in a home network and usually follow IEEE 802.11 standards.

  • A Wireless AP would cost between $45 - $120.
