Answer:
The decimal value of 101₂² base 2 = 25 base 10
Explanation:
The number 101₂² in decimal value is found as follows;
101₂ × 101₂ = 101₂ + 0₂ + 10100₂
We note that in 101 + 10100 the resultant 2 in the hundred position will have to be converted to a zero while carrying over 1 to the thousand position to give;
101₂ + 0₂ + 10100₂ = 11001₂
Therefore;
101₂² = 11001₂
We now convert the result of the square of the base 2 number, 101², which is 11001₂ to base 10 as follows;
Therefore converting 11001₂ to base 10 gives;
11001₂= 1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2 ¹ + 1 × 2⁰
Which gives;
16 + 8 + 0 + 0 + 1 = 25₁₀.

Answer: Storage devices are non-volatile devices. That means that when the power is removed from them, for example, when you switch your computer off, they retain their contents (unlike RAM, which is volatile – it loses its contents). You can then retrieve the contents next time you switch your computer on. Storage devices can be used to hold operating systems, applications and files, amongst other types of software. They are simply big suitcases – used only for storage. We have already seen that when you want to use an application kept on a storage device, it has to be moved to RAM before you can start using it. This applies to the operating system, your files and any other category of software. For this reason, RAM is sometimes known as Primary Memory whereas storage devices are often referred to as Secondary Storage devices.
