Networking / Internetworking FAQ's

Q: Do I have to buy a router to connect to my high-speed Internet access connection?

A: If you only have one PC, then definitely not, but you should invest in firewall software protection.

If you have multiple PCs, then a router can make your set up a whole lot easier, plus it can save you money too, especially if the router supports NAT. However, instead of using a router you can request multiple IP addresses

Q: What is QoS exactly?

• It stands for Quality of Service.
• A network running QoS will give priority over desired applications, and give fewer resources to other applications.
• Sensitive applications like VoIP and video can really benefit from QoS.

Q: Do you set up computers, servers, and printers?

A: No. We have done this in the past, but it is not our technical focus.
We can set up very small networks for the home or typical Amature Radio club. For larger networks with advanced Windows Networking (not to be confused with LAN/WAN networking) needs, you require a professional services company that specializes in that.
