Answer:
- A) [tex]2^{30}[/tex] kilobytes
- B) [tex]2^{30}[/tex] megabytes
- C) In order to convert the number of bytes per unit to the number of bits per unit you need to multiply the number of bytes by 8.
Step-by-step explanation:
Part A: How many kilobytes are there in 1 terabyte? The final answer should be left in exponential form.
1 terabyte = [tex]2^{40}[/tex] bytes
1 kilobytes = [tex]2^{10}[/tex] bytes
⇒ 1 terabyte = [tex]2^{40} / 2^{10} = 2^{30}[/tex] kilobytes
Part B: How many megabytes are there in 1 petabyte? The final answer should be left in exponential form.
1 megabyte = [tex]2^{20}[/tex] bytes
1 petabyte = [tex]2^{50}[/tex] bytes
⇒ 1 petabyte = [tex]2^{50}/2^{20}=2^{30}[/tex] megabytes
Part C: Another unit used to measure computer memory is a bit. There are 8 bits in a byte. Explain how you can convert the number of bytes per unit to the number of bits per unit.
In order to convert the number of bytes per unit to the number of bits per unit you need to multiply the number of bytes by 8.
1 byte = 8 bits
2 bytes = 2*8 bits = 16 bits
3 bytes = 3*8 bits = 24 bits
etc.
