Flashcards in 3j Broadband Connections Deck (3):
A member of the team, who lives in a remote location, has been offered a broadband internet connection.
Compare ADSL to a satellite connection for accessing the internet (3 marks)
2 full comparisons for marks
ADSL requires the user needs to be within a certain distance from a compatible local exchange whereas a satellite connection can be used in remote areas where physical and wireless connections are not available
ADSL is uses copper cable to connect whereas a satellite connection relies upon microwaves
ADSL offers sufficient bandwidth (Mb/s) to allow more data to be sent at the same time meaning large volumes of data can be handled at once whereas a satellite connection has a much lower bandwidth (Kb/s) meaning lower volumes of data can be sent at any one time
ADSL can handle simultaneous data and audio streaming whereas a satellite connection would mean multimedia files suffer delays and stoppages during their presentation on screen
both ADSL and satellite are asymmetric meaning downstream has a much higher bandwidth than upstream
The head office is investigating how to link the branches together.
(i) Explain two disadvantages to the estate agency of using a satellite broadband
connection to link the branches together. (4 marks)
Two from eg:
a connection requires satellite dish (1) may be planning applications
preventing its use (1)
dish requires line of site to the satellite (1) in a built up town this may
be difficult to achieve (1)
satellite signal affected by bad weather (1) staff will lose the signal in
snow/rain/wind preventing work (1).
