The answer is Undo I think
This program multiplies integer inputs A and B, by repeatedly adding B to RESULT while decrementing A.
It will work fine when either A or B is zero. If A is zero, it will branch to QUIT immediately. If B is zero, zero will be added repeatedly to the result (which also is initialized with zero).
LOOP, RESULT etc. are called labels. They translate into a memory address location of a variable or machine instruction. But it is much more readable to have them as english words while creating your program. Also, they make your program relocatable, in the sense that while writing, you don't have to decide on which physical address your program will run.

Answer:
PNG, GIF
Explanation:
On a Web page, we'll assume he'll have simple graphic elements like icons, or other simple low-resolution and a lower number of colors (256-), these are usually better saved in GIF format to take less space, just because of the smaller color map, but PNG could also do a great job and it offers transparency as well (like GIF does).
For more complex elements (larger size and/o more colors like photos), the best format to save them is probably the PNG one. They will be compressed but still offer a great quality.
Answer:
A field with a unique value
Explanation:
A primary key is a field (or a collection of fields) that contain a unique data to identify a precise row in a given table. This is used for data retrieval but also to fully identify the row to be edited in case of update.
It can be as simple as an auto-increment counter, a serial number or an email address for example.
It can also be complex and take into account a series of fields, like a combination of a date and a userID, as a simple example. In such case, the date field by itself would occur many times (many entries per day), and the userID would happen also many times (many daily entries by the userID), but the pair (date/userID) would be unique.
