Computers are NOT used for entertainment purposes in the area of publishing books.
Explanation:
- Computers are extensively used for entertainment purposes in various areas, but not in publishing books.
- The use of computers for entertainment purposes includes activities like playing/recording songs, drawing pictures, and watching movies.
- However, when it comes to publishing books, computers are primarily used for the creation, editing, and formatting processes rather than for entertainment purposes.

- While computers play a crucial role in facilitating these tasks, their primary function is to assist in the production and distribution of books rather than providing entertainment.

In order to identify the word that is not related to computers, we need to analyze the jumbled words and determine if they have any connection to the computer field.

• A: PNUIT - Upon unscrambling, we get the word "INPUT". This is related to computers as it refers to the data or commands that are entered into a computer system.


• B: SRPCOES - Rearranging the letters, we get the word "PROCESS". This is directly related to computers as it refers to the execution of instructions by a computer's central processing unit (CPU).


• C: TENIRS - After unscrambling, we find the word "INSERT". Although this word can have multiple meanings, it can also be related to computers when referring to the act of inserting data or objects into a document or file.


• D: THOWR - Rearranging the letters, we get the word "THROW". This word is not directly related to computers. It refers to the action of propelling something through the air with force, which is unrelated to the computer field.

Therefore, the word that is NOT related to computers is D: THOWR.

A flash drive, also known as a USB flash drive or thumb drive, is a portable storage device that connects to a USB port on the CPU box. It is a solid-state storage device that uses flash memory to store and retrieve data.
Here is a detailed explanation of each option:
- CD: CDs are optical storage devices that do not require a direct connection to the CPU box. They are inserted into a CD/DVD drive that is connected to the CPU box.
- Magnetic tape: Magnetic tape is a sequential storage medium that is used for backing up data. It is not directly connected to the CPU box but rather to a tape drive or a backup system.
- Microphone: A microphone is an input device used to capture audio. It is not a storage device and does not require a direct connection to the CPU box.
- Flash drive: Flash drives are portable storage devices that connect directly to a USB port on the CPU box. They can be used to store and transfer data.
In summary, the correct answer is Flash drive as it is the storage device that needs to be connected to a port present on the CPU box.
