Answer:

Data validation

Explanation:

Data validation is a process of checking and ensuring how valid a data is by comparing it with a set of rules or values. In other words, data validation checks for the validity of data. A data is valid if it is meaningful and correct.

For example, in validating a phone number, one might want to make sure it does not contain any letter. A phone number cannot contain but pure numbers and a few signs such as + and -.

In validating the last name of a person, one might want to ensure that it does not contain special characters such as @, #, & and so on. It has to contain nothing but letters.

you just bought a new hard drive for your computer you plan to use this as a secondary hard drive to store all um a files once i

mihalych1998 [28]

Well, you need to partition your hard drive. Partitioning your hard drive designates usable space on your hdd.

And you need to format your hard drive. Formatting installs a file system on to your hard drive, it allows the operating system to read, write and overall understand the data stored on the disk. Without it, an OS cannot keep track of file locations, nor can it typically identify already used sectors (space) on a hdd.
However, neither of these two concepts are tests.

Answer:

Explanation:

perform the following. write from right to left:

- is the number even? then write down a 0

- is the number odd? then write down a 1 and subtract 1

- divide by 2

- repeat until you reach 0.

So for 120:

120 is even, so write down a 0 and continue with 120/2=60

60 is even, so write down a 0 and continue with 60/2=30

30 is even, so write down a 0 and continue with 30/2=15

15 is odd, so write down a 1 and continue with 14/2=7

7 is odd, so write down a 1 and continue with 6/2=3

3 is odd, so write down a 1 and continue with 2/2=1

1 is odd, so write down a 1 and finish with 0
