What different terms mean the same thing (or don't, but people think they do)? [closed]

Answer 1

PC != Windows

PC means personal computer. Apple invented the PC. But, now it's taken a life of its own as anything that has Windows on it.

In this same vein, people tend to compare "Mac" or "PC" when it should be "OS X" or "Windows"... or "Mac vs. ThinkPad/Satellite"

Of course, that would be more difficult to put into an ad.

Answer 2

"Inconceivable"

I do not think it means what you think it means.

Answer 3

Winchester == hard disk drive.

It ain't!

Answer 4

I've seen this a few times on this site:

Authentication != Authorization

Authentication: Your identity
Authorization: Your privileges

Answer 5

Scope != Lifetime

Scope :: is the collection of statements where a variable can be referenced. Those statements are called the referencing environment of that variable.

Lifetime :: is the association between a variable(the name) and its place of storage in memory(address).

Answer 6

Closure == lambda. In reality, they are distinct things: lambda is any anonymous function, and may or may not close over some variables; closure is any function that closes over some variables, and may or may not be anonymous. For example, the original Pascal had no lambdas, but it had closures (in form of nested functions).
