HUB~$20 ($20 - $1,000+)

Best for:

• home networks

• light traffic business environment

• connecting multiple computers

HUB

Link computers and devices together (using Ethernet cord is required)

Shares bandwidth between all computers and devices (use of bandwidth effects entire network)

Transmits data to all computers and devices connected (excessive data transmission if only meant for one-on-one transmission)

Switch~$30 ($20 - $1,000+)

Best for:

• heavy use home networks

• business environment

• connecting multiple computers

• heavy multimedia use

Switch

Very similar looing to a HUB

Connects all computers and devices together (wired connection required)

Single address data transmission (will only direct data to computer or device intended for)

Every computer and device has dedicated link on network (high bandwidth use on one computer does not effect other devices)

Router~$50 ($20 - $300)

Best for:

• any home network

• most business environment

• connecting multiple devices (wired or wireless)

Router

Relays data to anywhere in the network or out of internal network

Links computers and devices to each other and internet (wired and wireless connections used)

Home/low-end routers support few computers and devices (usually 4 wired connections and a few more wireless)

High-end routers also available (allow for higher amount of connections)

Bridge~$70 ($40-$1000+)

Best for:

• Large networks

• Multiple networks

• Different networks used simultaneously

Bridge

Acts similar to a Switch

Connects, or bridges, networks together (can bridge multiple switches or hubs together to allow communication between them)

Allows for different networks to communicate with each other (can bridge different networks together even if hardware is different types)

Gateway~$40 ($20-$1000+)

Same as:

• HUB

• Switch

• Router

Gateway

A gateway provides a path or “gateway” from local area to wide area network

Many networking components actually act as a gateway (HUBS, Switches, Routers)

Internet

Firewall~already own(included in OS and modems, $30-$300)

Best for:

• Internet connected networks (business or personal)

• large networks (even if no internet connections)

Firewall

Firewalls are integrated in most operating systems (windows includes software firewalls)

Firewalls are included in most network modems (internet provider’s modems have firewalls)

Prevent unauthorized access to you network or personal computer

Internet

Wireless AP~$50 ($20 - $300)

Best for:

• any home network

• most business environment

• connecting wireless devices

• business with non permanent guests or customers

Wireless AP

Allows for wired or wireless connection (not restricted to physical wire connection)

Combination network switch and gateway (can connect computers and devices to each other and also the internet)

Can allow for anyone within certain distant to connect to network (no physical restrictions within rated distance)
