Which abbreviation represents a technology allowing devices to exchange data wirelessly over a computer network?

• CPU

• RAM

• WiFi

• LAN

Answer explanation

c - WiFi, short for Wireless Fidelity, represents a technology enabling wireless data exchange among devices over computer networks. Unlike CPU (Central Processing Unit), RAM (Random Access Memory), and LAN (Local Area Network), which serve distinct roles in computing, WiFi specifically facilitates wireless communication and data exchange across devices within a network.

What is the equivalent of 1,048,576 bytes?

• Kilobyte (KB)

• Megabyte (MB)

• Gigabyte (GB)

• Terabyte (TB)

Answer explanation

b - The relationship between bytes and their higher-order counterparts follows a consistent pattern where each higher unit consists of 1,024 of the previous unit. A Kilobyte (KB) is made up of 1,024 bytes, a Megabyte (MB) comprises 1,024 Kilobytes, and so on. Given this pattern, 1,048,576 bytes, which is 1,024 bytes multiplied by 1,024 bytes, aligns precisely with the definition of a Megabyte. Therefore, 1,048,576 bytes equate to 1 Megabyte (MB).

Convert the binary number 10011 to decimal.

• 17

• 18

• 19

• 20

Answer explanation

c - To convert 10011 from binary to decimal, apply the positional value to each digit. Starting from the right, the rightmost digit represents 2^0, followed by 2^1, 2^2, 2^3, and 2^4. Calculating the sum of the products yields 1 2^4 + 0 2^3 + 0 2^2 + 1 2^1 + 1 * 2^0, which equals 16 + 0 + 0 + 2 + 1, totaling 19.
