To what power of 10 does the prefix micro- refer? What is the (approximate) equivalent power of 2?

Answers

Answer:

1.Computer Organization is how operational parts of a computer system are linked together. Computer architecture provides functional behavior of computer system. ... Computer organization provides structural relationships between parts of computer system.

2. An ISA, or Individual Savings Account, is a savings account that you never pay any tax on. It does come with one restriction, which is the amount of money you can save or invest in an ISA in a single tax year – also known as your annual ISA allowance.

3. The principle of equivalence of hardware and software states that anything that can be done with software can also be done with hardware and vice versa. This is important in designing the architecture of a computer. There are probably uncountable choices to mix and match hardware with software.

4.Computer systems consist of three components as shown in below image: Central Processing Unit, Input devices and Output devices. Input devices provide data input to processor, which processes data and generates useful information that's displayed to the user through output devices.

5.What is the (approximate) equivalent power of 2? The prefix giga means 109 in the SI (International System of Units) of decimal system. Now convert to binary definition. So, the 1 giga =230 bytes.
