CHAPTER 1 - HARDWARE COMPONENTS

Which of the following best explains why the CPU is often called the 'brain' of the computer?

• It stores all data permanently

• It powers on the system and controls electricity flow

• It interprets and executes program instructions

• It connects all hardware to the Internet

When a computer is turned off, which type of memory will lose all its stored data?

• ROM

• RAM

• SSD

• HDD

Which feature of a microprocessor makes it different from early CPUs like the ENIAC?

• Larger size

• Requires manual programming with switches

• Smaller size but higher processing power

• Stores programs permanently

Which statement about ROM is incorrect?

• It stores data permanently.

• It contains instructions for starting the computer.

• It can be erased when the computer is turned off.

• It cannot be modified by the user.

What happens to a program when it is executed by the CPU?

• It is converted into a hard copy document.

• It is loaded into primary memory and processed.

• It is stored permanently in secondary storage.

• It replaces the BIOS instructions.

Why is SSD storage typically faster than HDD storage?

• SSDs use moving magnetic platters.

• SSDs use solid-state memory without moving parts.

• SSDs have a higher rotational speed than HDDs.

• SSDs store data in ROM chips.

Which scenario requires secondary memory rather than primary memory?

• Running a video game

• Saving a photo for long-term use

• Typing in a word processor before saving

• Storing data temporarily for calculations

A student plugs a USB drive into a computer and opens a project file. What type of storage is the USB drive using?

• Magnetic

• Optical

• Flash memory

• Volatile memory

Which is the primary purpose of cloud storage?

• To speed up CPU performance

• To store data on remote servers accessible via the Internet

• To replace RAM entirely

• To make computers boot faster

In terms of computer memory hierarchy, which order (from fastest to slowest) is correct?

• SSD → RAM → CPU cache

• CPU cache → RAM → SSD

• HDD → ROM → RAM

• RAM → CPU cache → HDD
