Thank you for making this video it has really helped me with revising content. I am currently in Y12 and doing the full a level this year to see how it goes and my teacher has kind of left me to it and has not really taught me anything. This has been a great help and would really appreciate one for paper 2.

[@s1perry]

Glad it helped!

[@kamo8741]

My teacher did it as well when I was in Y12. Don't worry about it too much, it's just to test your knowledge and how much you can do on your own. Treat it as practice for your mocks/real exam next year.

[@leopettecrew5695]

Note at 2:36, pipeling is NOT parallel processing, it is concurrent processing. Concurrent processing means running tasks one after the other. For example, one task may be started and a second may start after the first one, but before the first one has finished executing. Parallel processing is when multiple tasks are carried out at the same time.

[@MarwaMarwa-dg5oc]

aw nooo, a question came up asking you to define pipelining and I put down parallel

[@leopettecrew5695]

@@MarwaMarwa-dg5oc damn that sucks. yeah i thought it sounded wrong, so i did some last minute digging and found a mark scheme that gave concurrent, but not parallel. keep your head up though, it'll only be one mark plus it's "generous marking" so you might get away with it.

[@MarwaMarwa-dg5oc]

@@leopettecrew5695 a silly mistake, but eh just a mark, as you said. thanks for your comment ✌

[@s1perry]

It kind of depends on the context. If you are talking about CPU architecture where you are performing the stages of the FDE cycle at the same time, then yes, pipelining would count as a simple form of parallel processing for the exam board. You also have the idea of pipelining as a common computing technique where the output of one process can be fed into another, e.g. the classic UNIX pipeline with examples like ls -l | grep key | less.

[@leopettecrew5695]

​@@s1perry Maybe I'm just confused, but what you described in the video sounded like parallel, I agree. Fine line between the two to be fair. [ Taken from the A Level 2021 paper 1 - OCR ]: Question 1 b.) "The CPU uses pipelining to improve efficiency. Explain what is meant by the term 'pipelining'. [3]" Mark scheme states: • Concurrent processing of multiple instructions • One instruction can be fetched while previous is being decoded… • And the one before is being executed. • In case of a branch pipeline is flushed. • Increases speed of execution As a side note, I hate exams, expescially computer science. Love the subject immensely, but I've used so many revision resources and so many seem to contradict themselves it's hard to learn what's right and what's wrong somewhere else. Regardless, I found the video to be really helpful. Hope you come out with one for paper 2 soon! Also would love to know your thoughts on the first paper...

[@ashyvlogs1132]

[@s1perry]

Hope you do!

[@ElderlyAnteater]

@@camioso it was okay - didn't feel like it was anything to do with the advance info but I talked about things like political bias, and how the programmer could use keyword filters where they choose to censor a political opinion, and that a solution might be to make algorithms open source so people can see these things

[@camioso]

[@Daniel-ci4vt]

Thanks for this, just one point: I don't think you're allowed an intermediate step when asked to convert between bases. For example, in binary to hex conversion you won't get the marks if you convert to denary first

[@Daniel-ci4vt]

@@arnad.3313 I might be getting confused with other binary operations then, I've just done a past paper and yeah the binary to hex question had no guidance except the answer. My bad :)

[@PlankGraphics]

You are allowed to convert to denary for base switching. Only In binary addition you must not convert to denary first.

hi i am using the other method to do hexadecimal conversion where you convert it to binary first, but the number is too big for the first one to put in the table? and the second one where we convert 23f to denary, i try to convert it to binary and then to denary but i got 223?

[@maxwilde1621]

The table becomes 3 columns; 0101 = 5, 1011 = B, 0101 = 5 the headings being: 2048, 1024, 512, 256....128, 64, 32, 16.....8, 4, 2, 1 which makes it add to 1461 and again with 23f it becomes 2 = 0010, 3 = 0011, and f = 1111, which becomes 001000111111 = 575
