We use these terms or familiar with the concepts but there seems to be a but ----how all the time?
1. Bits, Bytes, and Size:
Every gigabyte, there's 1024 megabytes; 1024 kilobytes in a megabyte, and 1024 bytes in a kilobyte. Breaking it down to the lowest level, you've got 8 bits in a byte. In a flash drive, each bit of data is made up of eight separate floating gates, each comprising two physical transistors, which can basically record themselves as either a '1' or a '0'. Each floating gate actually relies on quantum mechanics to work. An 8 GB memory card has around 549,755,813,888 individual gates arrayed inside to save 8GB amount data.
2.Everything we see or hear on the internet is actually on our computer:
Every time we stream a video or the week's latest Top 40 off the web, it's actually, technically playing off our computer. The internet media file has to make a local copy of itself on our machine, first, before it starts playing. The buffering bar means on YouTube or Netflix is the amount of video that's been copied to the local cache, a.k.a. the amount we can still watch if the internet decides to up and die.
3. The distance data travels:
Every time we write down a link in the browser or click on a link, a request travels from our computer, through a local Wi-Fi router or a modem, up to a local data centre, from there onwards (under the Atlantic Ocean, if in the UK), all the way to the server were the webpage is stored, and back again – in around 0.1 of a second, depending on how good your internet connection is.
4. Counting Starts at Zero:
Each computer is actually a big calculator with lots of little logic gates representing 0 or 1. In the world of computer science, all counting starts at zero, not one.
5. The work that goes into a Ctrl+C, Ctrl+V:
When we want to copy some data, the solid state drives (SSDs) copies data from one bit to another.
It's not just a matter of shuffling the data from one part of the drive to another.
In practice, writing a tiny 4KB file can require the drive to read 2MB, store that temporarily,
erase a whole tonne of blocks, then re-write all the data.
