I agree with you about these.

in the 1970s which company develop innovations such as a mouse graphical user interface and word processing

2. The significant development featured in the Macintosh LISA computer was the Graphical User Interface (GUI).

4. The function NOT associated with a motherboard is peripherals.

10. To describe computers as "complex" can mean that they are understood by very few people because of their intricate technical components.

To answer these questions, we need to look at each option and determine which one fits the given criteria.

2. Which of the following components was a significant development featured in the Macintosh LISA computer?

The Macintosh LISA computer was known for introducing a significant development in computer technology. Let's look at the options:
- Option A: C Prompt - This is a command-line interface, not a significant development of the Macintosh LISA.
- Option B: Disk Operating System - D.O.S. is a type of operating system, but it wasn't a significant development of the Macintosh LISA.
- Option C: Graphical User Interface (GUI) - This is the correct answer. The Macintosh LISA computer was one of the earliest computers to feature a GUI, which revolutionized how users interacted with computers.
- Option D: Memory - While memory is an important component of any computer, it was not a significant development featured in the Macintosh LISA.

Therefore, the correct answer is (C) Graphical User Interface.

4. Which is NOT a function associated with a motherboard?

A motherboard is the main circuit board in a computer that connects various components together. Let's look at the options:
- Option A: Expansion slot - Expansion slots are present on the motherboard and allow for adding additional hardware to the computer, so this is a function associated with a motherboard.
- Option B: Memory - Memory modules are connected to the motherboard, so this is also a function associated with a motherboard.
- Option C: Processor - The processor is a key component that is directly connected to the motherboard, so this is a function associated with a motherboard.
- Option D: Peripherals - This is the correct answer. Peripherals, such as keyboards, mice, and printers, connect to the computer via various ports, but they are not a direct function of the motherboard.

Therefore, the correct answer is (D) Peripherals.

10. Many people describe computers as “complex” machines. What can this mean?

The term "complex" can refer to different aspects of computers. Let's look at the options:
- Option A: Computers are smarter than humans - While computers can perform complex calculations and process vast amounts of data, they are not generally considered to be smarter than humans.
- Option B: Computers are understood by very few people because of their intricate technical components - This is the correct answer. Computers involve intricate technical components and concepts that may not be fully understood by everyone, making them complex.
- Option C: Computers run software programs with hard-to-use features - While some software programs may have complex features, this answer does not encompass the overall complexity of computers.
- Option D: Computers have had both a positive and negative effect on society - Although computers have had both positive and negative effects on society, this answer does not capture the complexity of computers themselves.

Therefore, the correct answer is (B) Computers are understood by very few people because of their intricate technical components.
