Network Components

This assignment explores essential network components including hubs, switches, routers, bridges, gateways, firewalls, and wireless access points (APs). A hub connects multiple Ethernet devices by duplicating data to all ports, suitable for small networks. Switches improve efficiency by directing data via MAC addresses, ideal for larger LANs. Routers manage data traffic to home networks. Bridges connect distinct networks as one, while gateways facilitate broader network connections. Firewalls protect network traffic, and wireless APs enable Wi-Fi access in various settings.

  1. Assignment #3 Network Components

  2. Hub A hub is used for connecting many Ethernet devices together . A hub works on the physical layer (layer #1). It works by taking information received at one port and repeating/duplicating it to all other ports except the original. A hub would be useful in small networks where traffic is less of a concern. Price - $8.00 - $100.00

  3. Switch A switch like a hub connects multiple computers together on a network. Each component that is connected is identified by a MAC address The difference between a hub and a switch is that a switch doesn’t send the same information to all computers connected but to only the one that request that information. This information is passed along via a method called packet switching. Switches are often used in larger LANs. Price - $8.00 – $1,200.00 depending on the number of ports.

  4. Router A router takes data packets which it receives from the internet to the home network. A router also connect networks across the internet as it is able to pass data packets onto the next network until it reaches its destination. A router is used in most homes and small business. Prince - $20.00 - $200.00

  5. Bridge A bridge takes two distinct networks and “bridges” them together. They no longer function as two independent networks but as one. A bridge is very similar to both the hub and a switch. The difference is in that a bridge is mainly for LAN devices that employ Ethernet MAC addresses. The main function of a bridge is to inspect incoming messages and spend them to the to the correct location Price - $30.00 - $1,000.00

  6. Gateway The purpose of a gateway is to connect two networks together. Network gateways can work on all levels of the OISI model. On home networks a gateway is usually implemented within the router, to make things simple. Price - $50.00 - $1,000.00 +

  7. Firewall A firewall is a network based security system. Many times it can software that is placed on a personal computer that protects incoming and outgoing traffic that may or may not be trusted. Firewall are important and used by corporations, individuals, and families. $40.00 (software) - $600.00 (appliance)

  8. Wireless AP A wireless AP is a device that allows any device to connect to the Internet via a wifi signal. Wireless APs are used across most settings. Corporations may use them to provide wireless access across their LAN or to even create a hotspot at a local business like Starbucks. A wireless AP is also used by most ISPs to provide wireless access for residential homes. Price - $35.00 - $200.00
