The Internet Common Exam QuestionsGive the full name and give an example of the use of a LAN and a WAN - correct answer ✔✔Local Area
Network - Intranet
Wide Area Network - Internet / World Wide Web
What is a protocol? - correct answer ✔✔A set of rules
What is BAUD rate? - correct answer ✔✔The rate that signals/voltage changes are transmitted
What is the bit rate? - correct answer ✔✔The number of bits transmitted per second
What is the bandwidth? - correct answer ✔✔The range of frequencies a medium is capable of
transmitting
What is the relationship between bandwidth and bit rate? - correct answer ✔✔Greater bandwidth
allows greater bit rate
What is serial and parallel transmission? Give an advantage for each - correct answer ✔✔Serial
transmission is where bits are transmitted one after the other, the advantage is that is can be
transmitted over a longer distance (cabling is also cheaper and there is less chance of skew.) Parallel
transmission is where its are transmitted along several wires/channels/lines at the same time, the
advantage is that there is faster transmission.
What is asynchronous data transmission? - correct answer ✔✔Transmission of data without use of
external clock signal
Explain one purpose of a handshaking protocol - correct answer ✔✔To check that a receiving device is
connected
, What is latency? - correct answer ✔✔Time delay between the moment something is initiated and the
moment the effect begins
What are the functions of the start bit, parity bit and stop bit? - correct answer ✔✔The start bit
synchronises the receiver, the parity bit performs the parity check which will identify any errors I n
transmission and the stop bit allows the receiver to process received bits
The BAUD rate ad the bit rate of a communication channel may be different. Explain how this can occur. -
correct answer ✔✔A signal can contain one or more bits. Bit rate can be higher than baud rate because
bit rate = baud rate * number of bits per signal change
State one advantage (with reasoning) for both bus topology and star topology - correct answer ✔✔Bus
topology - lower cost due to reduced cabling / more flexible because it is easy to add or remove stations
Star topology - if one cable fails it only affects one computer because each computer is directly
connected to the central computer / it is simple to isolate faults as messages are sent directly / different
computers can transit at different speeds to the central computer
http://www.bargainbooks-r-us.co.uk/index.htm - what is the domain name of this supplier? - correct
answer ✔✔bargainbooks-r-us.co.uk
http://www.bargainbooks-r-us.co.uk/index.htm - what is the index.htm? - correct answer ✔✔The file
name / the page requested / the home page
Sometimes when the browser is used the software displays the error message 'Page Not Found'. Give
one possible reason for this, other than misspelling the URL - correct answer ✔✔The web server cannot
find the page requested / the page has been deleted / the page has been moved to a different folder /
the page does not exist / the page is in the process of being updated / the page is currently offline
Describe two benefits of connecting all libraries to a WAN. One should be a benefit for a library
administrator, and one a benefit for a borrower - correct answer ✔✔Administrator - electronic transfer
of documents between libraries, email communication with the outside world, backup of data/network
administration for all libraries is more manageable and done centrally
Borrower - email communication with the outside world / enquiries about books available at other
libraries / easier communication between the library and a borrower
