On a star topology network, a hub performs the function of a router. Like routers, hubs increase in price as more ports are needed, but a typical hub is a bit cheaper than a router. Shoppers can expect to spend $10 to $15 less for a hub comparable to a router with as many ports.
Common Network Infrastructure
Some forms of network infrastructure are common to both wired and wireless networks. A firewall is a network component that sits between a network and the Internet. It filters incoming and outgoing Internet packets, checking each incoming packet to ensure it is labeled as a reply to a previous request and the port numbers match. Any packet not matching these criteria and not passing the user-defined rules is discarded. Hardware firewalls can range in price from $50 to $5,000, depending on the number of ports, throughput, and maximum number of simultaneous sessions.
A modem, short for modulator/demodulator, modulates the properties of a carrier signal to encode the 1s and 0s that make up a data packet. A modem on one network converts the bits into an optical or audible signal and transmits the signal over the network medium to the modem on another network. The receiving modem then demodulates the signal, breaking the encoding and conv ...
