Are Hard Drives disappearing?
A good look at not only the question in the title, but also the different factors at play and what developments are being made. A must for GCSE Computing, gives good background for any storage related questions.
Taking apart a hard drive
This video goes through not only taking a hard drive apart, but also taking the working parts from another drive and swapping them over. Don’t try this at home. See that machine which they’re working in? That’s filtering out all the dust etc so the hard drive doesn’t get anything on it that would damage …. Read More
Which Operating System Reigns Supreme?
https://uk.pcmag.com/mobile-operating-system-2/126707/windows-vs-macos-vs-chrome-os-vs-ubuntu-linux-which-operating-system-reigns-supreme In year 8 we discuss what an operating system is, right where we cover hardware and software and search engines and web browsers. It’s something which comes up frequently on GCSE papers. This article discusses done of the most well known operating systems and what they provide. Most of it feeds in nicely with …. Read More
When AI wins in bizarre ways
Fantastic video which is essentially showcasing how AI does what you want, although not necessarily how you want it out even what you mean.
CURE Coronavirus From Home! – Folding@Home
Click bait headline, but interesting look at distributed computing. It’s been going on for years. I remember a similar one that was searching for aliens, literally. It was essentially helping some of the science projects that were scanning space for life markers. It was very sci fi, back then we lived in the future.
Getting data from websites
Interesting video from Tom Scott which covers various things. In a broader sense, ideology. In specifics, sharing data between web servers/services. In terms of specifications, A-Level interfaces (not the interface between human and machine, but the interface between one system and another). It’s a good watch, and an essential watch for A-level students.
Maths Challenge 1 in Python
Matt Parker does some awesome maths stuff, particularly his spreadsheet standup routine which is an excellent look at how images are stored and displayed. This is an interesting puzzle, and one that can be modelled in Python….your task, is to model it in Python! Give it a go and I’ll do a couple of videos …. Read More
9 quintillion stops
Have you every got onto a train and given a heavy sigh as you realise there’s still 9,223,372,036,854,775,798 stops until you reach home? It seems someone made a mistake. This video goes nicely into how this mistake could have happened and looks at some of the binary etc behind it. Worth a watch for years …. Read More
Why RAM prices change
This video is explaining why RAM prices are….volatile (see what I did there?). Whilst it’s interesting in itself, it’s also interesting to note how widely used RAM is, how many different devices use it. The amount CPU chips for example are used is a lot less because there’s a lot more specific CPUs then there …. Read More
Network Layers
https://medium.com/@james_aka_yale/the-4-layer-internet-model-network-engineers-need-to-know-e78432614a4f GCSE students (and A-Level students) will be familiar with the network stack…well…they’ll know it’s something they should know. It is however something which people are often fuzzy on. This article explains it nicely and talks about TCP and UDP and how it fits within the stack. Don’t worry about the OSI model, that’s something …. Read More
