When one is typing on MS word and one save the file, this data would be stored as combination of 1s and 0s in the computer.
- Computer data storage can be regarded complex system, immediately a data is saved then;
- The first be converted to simple numbers of 1s and 0s , this number are very easy for a computer to store and these number are regarded as Binary Numbers and all letters as well as photographs are converted to numbers,
- The hardware will record this saved numbers inside the computer.
- These numbers are then organized and transferred to temporary storage which be manipulated by programs, or software.
Therefore, data are been stored as 1s and 0s in the computer.

Answer:
C. FIFO
Explanation:
The first-in, first-out (FIFO) page replacement algorithm is a low-overhead algorithm that requires work on the part of the operating system. On a page fault, the frame that has been in memory the longest is replaced.
Using FIFO algorithm implies that
a page which was brought into memory first will be removed first since variable was initialized very early. it is in the set of first in pages that will be removed.
It is the simplest page replacement algorithm. The operating system keeps track of all pages in the memory in a queue, the oldest page is in the front of the queue. When a page needs to be replaced page in the front of the queue is selected for removal that is first in first out.
A memory page containing a heavily used variable that was initialized very early and is in constant use is removed, then the page replacement algorithm used is called First In First Out.
Answer:
00100110
a and d are invalid sequences because they contain an even number of 1's.
Explanation:
Odd parity means that you want an odd number of 1's in the resulting set of bits. Since there are 3 (=odd) bits in the set, a zero must be added to keep the total odd.

However, one can create a macro that would do the conversions :
1) Identify a list of words whose spelling you want to convert.2) Turn on the macro recorder. 3) Use the Replace feature to replace the spellings.4) Turn off the macro recorder.
The macro will do a conversion from one to the other. Later, as we have more words that need to be automatically replaced, we can just edit the macro and add those words.
