    You should put small tests at the end to ensure the people who are revising understand the video subject

    This became much longer than I wanted, so here are timestamps if you (understandably!) want to skip bits:
    0:00 - Intro and the art of cramming
    3:23 - What you need to know to start revising (Exam board & component & year of course)
    5:26 - The most important document: the specification
    6:29 - The need to be sceptical when using resources
    8:33 - Overlapping resources
    10:43 - Evaluating my own revision material
    16:21 - What you could do, using my videos
    18:57 - Computer Science exam specific stuff
    22:19 - To summarise, some dos and don'ts of revision

For the long answer questions, you really just want to write as much as you possibly can, even if you’re not sure it’s right, you are just more likely to pick up marks that way. In general, you want to do the practice papers as much as possible because repeat or similar questions do come up, so try and remember your answers for those and you should be ok

  • @ramanabalachandhran
    @ramanabalachandhran 5 років тому +1

    I'm wondering about the level of detail of information from the coursework that the examiner expects us to know. Would be happy if you could help.
    For example:
    Does it suffice to know that a DNS maps domain names to IP addresses, connects the computer to servers (like ANSs, resolver servers, etc) to retrieve the IP address from the root server? Or should I learn about DNSs in this much detail (I made a flashcard):
    (Domain Name System):
    Computers don't take the trouble of dealing with other computers for their IP Addresses. The DNSs do the job for them.
    Here's the formal definition: a hierarchical distributed database installed on domain name servers that is responsible for mapping a domain name to an IP address.
    Important points:
    ⚫ The DNS is designed to scale, so how much ever the internet grows, it doesn't matter. DNS to the rescue!
    ⚫ The domain name space is divided into zones. Most powerful root servers at the top (with the database stored),
    zonal primary servers, secondary servers, until the name server in the lowest domain.
    ⚫ There are more than 250 top-level domains which are either generic (.com, .edu, .org, etc) or represent countries (.de, .uk, .in)
    ⚫ The domain name is included in a uniform resource locator (URL), which identifies a webpage, or an email address.
    A domain is named by the path upward from it. For example, .eng.cisco.com refers to the .eng subdomain in the .cisco domain of the
    .com top-level domain (which is the reverse of that used for a pathname of a file).
    Name resolution:
    Looking up for a domain name to find an IP address is called 'name resolution'. For such a query there are three possible outcomes:
    ❁ If the domain is under the jurisdiction of the server to which the query is sent then an authoritative and correct IP address is returned.
    ❁ If the domain is not under the jurisdiction of the server, an IP address can still be returned if it is stored in a cache of recently requested addresses but it might be out of date.
    ❁ If the domain in the query is remote then the query is sent to a
    🡆 root server which can provide an address for the
    🡆 name server of the appropriate top-level domain which in turn can provide the address for the
    🡆 name server in the next lower domain. This continues until the
    query reaches a name server that can provide an authoritative IP address.

    My exams are in under 2 months for aqa a level computing my coding skills are very weak what tips do you have to improve my skills in this time, I find it hard to make algorithms or think how to solve problems or when I do just to convert my pseudo code to the coding language that I use(which is vb.net) do you have any tips or websites that are useful to improve my skills. I've been told to play with coding but I don't really know exactly what to do when people say that

    • @MrBrownCS
      @MrBrownCS  6 років тому

      It depends what exam you're doing (I know an AS one is on-screen), but generally the majority of the exam is theory so focus on that. You can also learn programming theory e.g. what variables, subprograms, etc are without being the best programmer (lots of questions will be on that stuff). You might wanna watch VB tutorials on youtube, but as I said make sure everything else is ok!
