What Is a Byte? Bits, Bytes, and Why Eight — Network Fundamentals Ep 2
One byte: 01001001. Is it the number 73, the letter I, a pixel's brightness, or a sound level? All four. The bits never change — only the agreement about what they mean.
Episode 2 of Network Fundamentals starts from absolute zero: what a bit actually is, why computers use two states instead of ten, how eight became the standard group, what a single byte can represent, and the two unit traps that confuse almost everyone — the 1 TB drive that shows 931 GB, and the 100 Mb/s connection that downloads at 12.5 MB/s.
No prior knowledge assumed. Nothing skipped.
Chapters 0:00 The smallest thing — what a bit is 0:58 Why eight — how the byte got its size 2:05 What a byte becomes — one byte, four meanings 3:14 Counting them — KB, MB, GB, TB, and the 931 GB question 4:18 The trap that costs you — Mb vs MB
