Answer:

The rank of disk capacities in decreasing order is:

1.petabyte,

2.terabyte

3.gigabyte

4.megabyte

5.kilobyte

Explanation:

Petabyte is largest among all and 1 petabyte equal to 1024 terabyte

Kilobyte is smallest among all and 1 kilobyte equal to 1024 byte

1 megabyte is equal to 1024 kilobyte

1 gigabyte is equal to 1024 megabyte

1 terabyte is equal to 1024 gigabyte

Which technological tool is important for storing critical files?.

Vanyuwa [196]

The technological tools that can be considered important for storing critical files are battery backup systems and drives. These devices can be used to store data and supply energy.

<h3>Battery backup systems</h3>

A home battery backup system is a device used to keep the electrical system working in the event when the electrical source goes down.

In computation, there are three major classes of batteries systems: Lead-Acid, Nickel-Cadmium, and Lithium-Ion.

An uninterruptible power supply (UPS) can be considered as a battery backup supply capable of charging when the power is on.

A digital computer has a memory unit with 16 bits per word. The instruction set consists of 72 different operations. All instruc

OLga [1]

Answer:

a. 7 bits b. 9 bits c. 1 kB d. 2¹⁶ - 1

Explanation:

a. How many bits are needed for the opcode?

Since there are 72 different operations, we require the number of bits that would contain 72 different operations. So, 2ⁿ ≥ 72

72 = 64 + 8 = 2⁶ + 8

Since n must be an integer value, the closest value of n that would contain 72 different operations is n = 7. So, 2⁷ = 128

So, we require 7 bits for the opcode.

b. How many bits are left for the address part of the instruction?

bits left = bits per word - opcode bit = 16 - 7 = 9 bits

c. What is the maximum allowable size for memory?

Since there are going to be 2⁹ bits to addresses each word and 16 bits for each word, the maximum allowable size for memory is thus 2⁹ × 16 = 512 × 16 = 8192 bits.

We convert this to bytes

8192 bits × 1 byte/8 bits = 1024 bytes = 1 kB

d. What is the largest unsigned binary number that can be accommodated in one word of memory?

Since the number go from 0 to 2¹⁶, the largest unsigned binary number that can be accommodated in one word of memory is thus

2¹⁶ - 1
