Some questions about today's technology:
What is a "bot" program, as opposed to other kinds of computer programs?
What allows and causes a foreign unauthorized program to start execution on a computer where it doesn't belong? In other words, who presses the start button on a supposedly personal computer to run sabotage? I don't understand how some external person can gain control of my computer, as if my neighbor could drive my automobile from his kitchen window.
What allows a private computer to be scanned by external means (like Spock using his scanners on a planet far below) so that its internal software may be examined and manipulated?
Who wrote such code?
Lastly, why do such vulnerabilities exist in the first place? I keep reading how the present Windows operating system is old; shouldn't all the necessary fixes be developed by now?
How much does it cost for companies to keep applying these patches every week?
