If only four computers are transmitting digital data over a T-1 line what is the maximum possible data rate for each computer?

Multiplexes 4 channels

Each frame has 8 bits per channel plus one framing bit

Frame size= 4*8 + 1 = 33 bits per frame

For voice each channel contains one word of digitized data (PCM, 8000 samples per sec)

Data rate 8000x33 = 0.264 Mbps

If Mac address then why IP address?

MAC addresses, unlike IP Addresses, are not divided into "host" and "network" portions. Therefore, a host cannot determine from the MAC address of another host whether that host is on the same layer 2 network segment as the sending host or a network segment bridged to that network segment.

This is kinda simplified,

The MAC address is hardware related. It identifies the "machine". It can't be changed without exchanging the part.

Where as the IP number identifies the "computer" in a "network". You can give the computer different "address's". It tells them the information as in the answer above.

Kinda like your home address number and your Social Security number. Your SSN is your MAC address and your home address is your IP#. It tells you what state, county, city and street you live in. If you change houses then you change address's.

What are the implications of thin and fat clients for a server?

"Fat" clients already have their software (OS, apps, etc.) usually available to them. A "thin" client does not, and therefore has to download the software from a server.

The net effect would cause the server to be busier (depending on the number of thin clients making requests). It may also take several attempts to successfully download the software depending on network quality.

The job of a web server is to process and respond web?

A web server is very similar to a file server; the difference is that it holds web pages instead of files (although web pages are stored in files).

A web server waits on HTTP requests and responds with HTTP answers usually formatted in HTML/XHTML.
