No Ethernet is a low level standardized protocol for sending data. It is the protocol your computer sometimes uses to send data over a wire to another computer(usually a router or switch). Higher level protocols use lower level protocols to send their data. IP for example can use Ethernet to get from computer to computer or router to router. TCP can use IP to get from a starting computer to an ending computer through many computers along the way. HTTP(what the web uses) uses TCP to get from port on one computer to port on another and to keep information in order and not lost. Answers.com uses HTTP to get this answer to you.

Not directly, no. The connector types are different, for example. Also, the devices you connect to would need to be changed to accomodate the different cable media.

IP address is a private Class A address10.0.0.0 for very large networks which can hold as many as 16 million computers. These are addresses that IBM, Geneal Electric and Apple use. The first 3 numbers of the class A IP address is 126. Then they use the 10.0.0.0 to set up private computers within the company. Another example is the IP address 192 thru 223, these are Class C networks which are for small networks. Then within that address there is 192.168.0.0 to 192.168.255.0 to set up private networks within that class.

because for the set binary number it will be 11111111 which is in hexadecimal is FF = 255

Judging from the tech specs page on the Viewsonic PJ503D projector, it takes standard VGA input. The PowerBook G4 12" has a mini DVI out port. So, the adapter you would need is a mini DVI to VGA adapter (which should have come included with the PowerBook, or is readily available at your local Apple store or Apple online).

No. Only protocols that users can see on their screen are considered Presentation Layer based.

Hubs and repeaters operate on the physical layer, because it doesn't do anything with the data, it simply forwards it.

Basically, the faster the LAN the faster you get information from one system to another. It all comes down to how much data you are transferring (internally) and how quickly you want to get it there.

In most companies, even internal communications seem slow to users at times. Most users want the fastest connection they can get.

it is a wireless lan card

Reserved IP addresses are

10.0.0.0 to 10.255.255.255

172.16.0.0 to 172.31.255.255

192.168.0.0 to 192.168.255.255

and

169.254.0.0 to 169.254.255.255

Every address in these ranges is considered reserved or private,

meaning the internet will NOT route to them without an NAT.

These addresses are not assigned to devices because they have a reserved meaning. All zeroes refers to "this network", and all ones usually is assigned to a broadcast address (all devices).

You need a dedicated circuit for carrying voice communications that cannot be shared with others. That won't happen with packet switching, which will result in choppy and non-understandable conversations.

Because it makes all computers who have something to say wait until they get the token. Some info that needs to be sent may be very important but if it doesn't have the token then too bad. It'll have to wait.

Elevation is a Microsoft Windows term; other operating systems have a similar concept under a different name. Normally, Windows runs in "restricted" mode, which prevents applications from installing without the user's knowledge or consent, and prevents unauthorized changes to the system's parameters.

In order to configure the system or install a new application, Windows will request "elevation" from the user. This means that the system needs more than "restricted" access, and needs to move up to "admin" access in order to complete the process. Once the process is complete, the system returns from its "elevated" status of "admin" back to the "restricted" mode.

You should only authorize an "elevation" if you specifically requested a change to your computer or are attempting to install a new application. If you did not request any changes, you should instead not allow the "elevation" to occur, which will prevent malicious software from taking over your system.

It is when you connect 2 computers with a LAN cable

this does appear to be a networking question.
