[…] Another point noticed was the widespread use of small-package solid-state logic (such as "and," "or," "not") and instrumentation (timers, amplifiers, etc.) units.

The automatic telephone switchboard was introduced in 1892 along with dial telephones. By 1929, 31.9% of the Bell system was automatic. Automatic telephone switching originally used vacuum tube amplifiers and electro-mechanical switches, which consumed a large amount of electricity. Call volume eventually grew so fast that it was feared the telephone system would consume all electricity production, prompting Bell Labs to begin research on the transistor.
Each time you press F8 the line of code highlighted in yellow will execute, and then the next line down of code will turn yellow and wait for your key press. Say you change the code in a line and want to re-run it… you’d move the yellow line back up by dragging the yellow arrow with your mouse, or by clicking the line you want and then pressing CTRL+F9
