Why is a start bit used in asynchronous communication?

Asynchronous (serial) communication means that all the necessary decoding information is carried in the data stream, with no need for any external timing reference. The start bit is needed to tell the receiver that the next so-many bits are data. Likewise, the stop bit tells the receiver that the byte or packet has ended, and it can check to see if it received the correct number of data bits between the start and stop bits. Think of it this way, if you transmitted 0 asychronously without a start bit, how would the client know a byte had been sent? There would be no state change on the line.

Can you use Windows XP as a network operating system in a client server network or do you need to purchase Windows 2000 server?

To my knowledge...there is no network server version of XP. The equivalent would be Server 2003. Neither Windows XP Home nor Windows XP Professional are designed to be used as a "server" in a client-server network. However, they can be easily set-up as a peer-to-peer network, and you are free to designate any or all of the workstations on a peer-to-peer network to function as a "file-server"... In other words: choose one of your nodes as the central location for storing files, data, drivers, installation programs, downloads, etc. and share those files with any or all of the remaining workstations. Many networkable programs will function just fine in this arrangement (MS Office, among others). What it lacks is the security features, logon restrictions, etc., etc., that a true client-server network offers. Be aware that Windows XP Home cannot login to a client-server environment (domain). You must have Windows XP Professional in order to be able to login to the server. So, the short answer to your question is: You NEED to purchase Windows Server 2000 or Windows Server 2003 (My recommendation is that you buy 2003... the licence is backward "compatible", so you can always install prior versions of Windows Server software, NT, 2K or whatever, (instead of 2003) if you wanted to, and still be within your licencing agreement.)

If you have an 8 mm camcorder can you buy software to make home videos on your computer from 8 mm tapes?

You need video editing software and a way to get the images into the computer. As an 8mm camcorder has only an RCA Composite output, this will require you to have a comparable input on your computer. You use the camcorder to play the tapes and input them into the computer. It will be necessary to purchase and install a composite video input card.

How do you DMZ your local IP to get around a firewall that the network server has and open up certain ports so you can get out on 'STEAM'?

A DMZ or DeMiliterized Zone is something that has to be created on the firewall. If you want to setup a DMZ and only have one PC and one firewall, then it is pointless to have the firewall in the first place. If you are in a corporate environment and do not know how to access the firewall, then you should not be setting up your computer on a DMZ. If you have several PCs on your home network and can access your firewall, then you need to look at the documentation for your firewall and it will tell you how to configure a DMZ. It should be noted however that Steam currently does not support operation through a network DMZ. Quoting a steam tech support email: "If your machine is currently in a network DMZ, you will need to reconfigure your network to play through Steam."

Typically, Gaming needs Steam and the only inhibitor is not the outbound, but rather the failure to port forward

  • Steam-1 27000--27015
  • Steam-2 27020--27050

to the gaming system's ip address (obviously it must be a static LAN address)

Where can you delete the client license in Windows 2000 terminal server?

How can 10 computers on an ethernet network using a switch and 5 on a wireless network share an internet connection?

You need a router. The cable modem connects to the modem's uplink port and the switch can connect to any available port on the router. This wll enable any computers connected to either the router or the switch to access the internet.

Through a Wireless Access Point/Gateway/Router.

How do you network two computers in different rooms and have them sharing an ADSL Broadband connection?

You need to buy an adsl router. Connect your modem to the router then connect your two computers using rj45 (ethernet) cables or usb. Some routers need to be a modem router which renders your broadband router useless. Some broadband companies require you to register every PC used on the network sharing the internet.

And sometimes you can get a wireless router but it takes a while to install.
