Today, hard-drives or hard-disks store an incredible amount of data. I remember when I did my computer-science engineering, my hard-disk was 2GB and my RAM was 32MB. Today, in the 3.5 inch disk, we store tera bytes of data – that is how fast things have changed in two decades. Below is a Seagate hard-drive

In the Part 1 of this article, we learnt that devices connect with each other using different wired ports. Each of these ports are either serial or parallel in communications. Within the serial and parallel communications, we have different protocols (ways) of communication. Let’s say we want to send 8 bits of data from one

We take a USB drive, plug it in our computer or TV, and voila! We transfer the files or play from the drive. So, how is it that computers or digital devices are able to talk to each other? Essentially, devices talk to each other by connections between ports. We use ports to connect to
