2. This stands for Random Access Memory. Computers use it to store instructions and data while it is running.

RAM stands for Random Access Memory. It is a type of computer memory that is used to store instructions and data while the computer is running. RAM is volatile, meaning that its contents are lost when the computer is turned off or restarted. It allows the computer to quickly access and retrieve data, which helps in improving the overall performance and speed of the system. R.A.M. is just an abbreviation for RAM, both representing the same concept.

6. The computer's immediate internal PRIMARY memory - it is fast, easily accessible, and allows the computer to complete many tasks at once - but it but does not last when the power goes out and is not useful for permanent storage.

Secondary memory

RAM

DVD

Hard disk

RAM (Random Access Memory) is the computer's immediate internal primary memory. It is fast and easily accessible, allowing the computer to complete many tasks simultaneously. However, RAM does not retain data when the power goes out, making it volatile. It is not suitable for permanent storage as it is designed for temporary storage of data that the computer is actively using. Secondary memory, such as a hard disk or DVD, is used for long-term storage of data.

CPU

Motherboard

Application

Operating system

The operating system is the main computer program that directs all the activities and sets rules for how hardware and software work together. It acts as an intermediary between the user and the computer hardware, managing tasks such as memory allocation, file management, and device input/output. The operating system provides a platform for other software applications to run on and ensures that they can communicate with the hardware effectively. Without an operating system, a computer would not be able to perform any tasks or run any programs.

13. The smallest piece of information used by the computer. This very short word is an amalgamation (a combination) of the words "binary" and "digit".

A bit is the smallest unit of information used by a computer. It is a combination of the words "binary" and "digit". In computing, information is stored and processed in binary form, which means it is represented using only two digits, 0 and 1. A bit can represent either a 0 or a 1, and it is the fundamental building block for all computer data. Multiple bits combined together form larger units of information, such as bytes, kilobytes, and so on. Therefore, the correct answers for this question are "bit", "bits", and "a bit".

14. This early computer weighed 30 tons and was built for the US army in the 1940s

IBM

ENIAC

IPad mini

HAL

ENIAC is the correct answer because it was an early computer that was built for the US army in the 1940s and it indeed weighed 30 tons. IBM is a well-known computer company, but it does not specifically refer to the early computer described. iPad mini is a modern tablet and HAL is a fictional computer from the movie "2001: A Space Odyssey", neither of which fit the description of the early computer.

15. True or false - digital information is recorded in a continuous stream of data, like sound waves on a record player or a graphic representation of earthquake energy (a seismometer). An example of digital information is a cassette tape. This is different from analog information, which is recorded as a combination of 1s and 0s.

True

False

The given statement is false. Digital information is not recorded in a continuous stream of data like sound waves or a seismometer.

19. How do you represent the number 3 in binary?

001

010

011

3.14159

The number 3 in binary is represented as 001. In binary representation, each digit can be either 0 or 1. The rightmost digit represents the value of 2^0, the next digit represents the value of 2^1, and so on. In this case, the rightmost digit is 1, indicating that 2^0 is included in the binary representation of 3. The other two digits are 0, indicating that 2^1 and 2^2 are not included. Therefore, the correct binary representation for 3 is 001.
