No guess paper is authentic and the same as CIE exams. There is also no need for 'authentic' guess papers especially here in this ATC, everything's the same each year. Just go through the pattern and mark schemes and practice System Flowcharts.

-"each track requires separate sampling for left and right speakers of a stereo recording "
This means that in one second,
Number of bits required = 16*44100*2 = 1411200 bits
1 bit = 8 bytes,
Therefore,
Bytes required = 1411200/8 = 176400 bytes.

-Number of bytes required for 3 minutes = (44100*2*16)/8 * 180 = 31752000 bytes
1 MB = 1024^2 bytes.
Therefore,
Number of MB required = 31752000/1024^2 = 30.28 MB.

advantages depend on the previous one. If the older one is also computerised but not online and new one is online then advantages will be that now it can be accessed anywhere in the world. The users can book at hime sp they dont need to come first. Less load at the booking office ets. If the older one is not computerised then advantages will be faster operations, less errors, less employees, less space for papers etc.
Limitations can be... Anything that new system cant do. Such as if servers overloads or have ddos attack then customers cant use it etc. depends on the case study.

 

[KWIKIW]

Can anyone give me some flowchart symbols?

 

[guestp]

Thanks! And what about the flowcharts question?
