Christopher Sholes invented the QWERTY keyboard layout in 1873 for his typewriter design, which became the standard layout. While keyboard-like input devices existed earlier, Sholes is credited with the modern typewriter/computer keyboard. Constant Martin, Douglas Engelbart (invented the computer mouse), and Ken Thompson are not associated with keyboard invention.

Tim Patterson created QDOS (Quick and Dirty Operating System) in 1980, which Microsoft purchased from Seattle Computer Products and renamed MS-DOS. Patterson wrote the initial code, while Microsoft (led by Bill Gates) adapted, licensed, and marketed it. Gary Kildall created CP/M (a competing OS), Dennis Ritchie developed Unix, and Larry Ellison founded Oracle.

Ada Lovelace is recognized as the first computer programmer for her work on Charles Babbage's Analytical Engine in the 1840s. She wrote what is considered the first algorithm intended to be processed by a machine, making her the pioneer of programming. Charles Babbage designed the computer hardware, but Lovelace created the software concept.

By 2006, email had become a dominant communication method globally, with approximately 50 billion emails sent daily. This reflects the massive growth of digital communication in the early 2000s as internet adoption accelerated worldwide. The number includes both personal and business communications.

In 2010, India had approximately 100 million internet users while Facebook had around 15 million users, giving a ratio close to 20:3. This reflects the early stages of social media adoption in India's growing internet market. The ratio shows Facebook's rapid but incomplete penetration among Indian internet users.

The shebang (#!) is a special character sequence at the beginning of Unix script files that tells the operating system which interpreter to use. It's followed by the path to the interpreter program (like #!/bin/bash or #!/usr/bin/python). This convention is essential for making executable scripts on Unix-like systems.

Dennis Ritchie, co-creator of Unix and the C programming language, is credited with introducing the 'Hello World!' tradition. While Brian Kernighan popularized it in his famous C programming book, the practice originated from Ritchie's early C programming examples at Bell Labs. This became the standard first program for learning new languages.

According to the International Obfuscated C Code Contest (IOCCC), the smallest 'program' is technically zero bytes - an empty file that compiles successfully in C. This exploits C language rules where empty translation units are valid. The contest celebrates creative, minimal, and obfuscated C code.

W3C was founded by Tim Berners-Lee in 1994 and he continues to serve as its Director. The consortium develops web standards like HTML, CSS, and HTTP.
