IBM sold a mouse with a pointing stick in the location where a scroll wheel is common now. A pointing stick on a mid-1990s-era Toshiba laptop. The two buttons below the keyboard act as a computer mouse: the top button is used for left-clicking while the bottom button is used for right-clicking.
A modern PC with a bus rate of around 1 GHz and a 32-bit bus might be 2000x or even 5000x faster, but might have many more gigabytes of memory. With boot times more of a concern now than in the 1980s, the 30- to 60-second memory test adds undesirable delay for a benefit of confidence that is not perceived to be worth that cost by most users.

TCP sequence numbers and receive windows behave very much like a clock. The receive window shifts each time the receiver receives and acknowledges a new segment of data. Once it runs out of sequence numbers, the sequence number loops back to 0. When a receiver advertises a window size of 0, the sender stops sending data and starts its persist ...
