Edexcel GCSE Computer Science: The Internet & the Web - Topic 21 [OLD COURSE]

Показать описание
Covering: IP addresses, domain names, URLs, routers, ISPs and what is meant by the connecting backbone, the World Wide Web, HTTP and HTTPS, some theory about HTML and CSS, the client-server model and client/ server side processing.

As I mentioned I highly recommend you learn some bits of CSS and HTML, these videos might be useful (and are short!):

Thank you. Just thank you. My teacher told our class we would be lucky to get a C. We had barely covered the syllabus in the 2 years we had, and recently changed exam boards due to time constraints. But because of your videos, I ended up getting a B - which could have easily been a fail. So again, thank you :)

Do we need to know the full sequence for DNS ie, ISP DNS -> Root Server -> Top level domain DNS -> domain owner DNS -> client etc or just the basic sequence you said?

Would it be possible to upload a few videos tailored for the WJEC computer science syllabus?? I have been using the OCR videos for revision but it would be really useful. I understand if you don't have time:)
