meaning of tif

1. TIFF Tagged Image File Format tiger team US military jargon 1. Originally, a team whose purpose is to penetrate security, and thus test security measures. These people are paid professionals who do hacker-type tricks, e. g. leave cardboard signs saying "bomb" in critical defence installations, hand-lettered notes saying "Your codebooks have been stolen" they usually havent been inside safes, etc. After a successful penetration, some high-ranking security type shows up the next morning for a "security review" and finds the sign, note, etc. and all hell breaks loose. Serious successes of tiger teams sometimes lead to early retirement for base commanders and security officers see the patch entry for an example. 2. Recently, and more generally, any official inspection team or special firefighting group called in to look at a problem. A subset of tiger teams are professional crackers, testing the security of military computer installations by attempting remote attacks via networks or supposedly "secure" communication channels. Some of their escapades, if declassified, would probably rank among the greatest hacks of all times. The term has been adopted in commercial computer-security circles in this more specific sense.

Consider the following pointless BASIC loop that counts upward indefinitely 10 i = i + 1 20 GOTO 10 Run on a single-user system such as MS-DOS this will not cause any problems. Run on a cooperative multitasking operating system such as Windows 3, the system would appear to freeze. A pre-emptive multitasking operating system such as UNIX or Windows NT would "steal" cycles away from the program and continue to run other programs. See also busy-wait and multitasking.
