c)     An address
d)    All of above
e)    None of these
Answer: C)
Explanation: The memory has specific locations in the system and every program or every file is stored at a particular location in the memory. This is also referred to as address in the memory.

9. Binary numbers need more places for counting because
a)    They are always big numbers
b)    Any no. of 0's can be added in front of them
c)     Binary base is small
d)    0's and l's have to be properly spaced apart
e)    None of the above
Answer: C)
Explanation: In mathematics and digital electronics, a binary number is a number expressed in the binary numeral system or base-2 numeral system which represents numeric values using two different symbols: typically 0 (zero) and 1 (one). 

10. Which command is used to delete everything in a directory?
a)    Delete
b)    Del
c)     Deltree
d)    Move
