A) census taking
B) code breaking
C) communication
D) troop placement

Accepted Answer

The first digital computers, called Colossus, were built during World War II for code breaking purposes by the British.

Question 3

Digital electronics use ____ to represent data.
A) circuits
B) switches
C) transistors
D) components

Accepted Answer

The answer of Digital electronics use ____ to represent data.
A)...

Question 4

The set of instructions that tells a computer how to carry out processing tasks is a computer program .

Accepted Answer

A computer program is a set of instructions that tells a computer how to execute tasks or solve problems.

Question 5

Initially sales were slow for the personal computer because of ____.
A) price
B) size
C) lack of software
D) lack of availability

Accepted Answer

Although price and size were also factors, the main reason for slow sales of personal computers in the beginning was the lack of available software. Without software, consumers had no reason to purchase a personal computer.

Question 6

Key factors in making electronic devices increasingly smaller and less expensive include ____.
A) transistors
B) integrated circuits
C) a & b
D) neither a nor b

Accepted Answer

Transistors and integrated circuits are key technologies that enable electronic devices to become smaller and less expensive. Transistors act as switches or amplifiers in electronic circuits, while integrated circuits combine multiple transistors and other components onto a single chip. By reducing the size and complexity of these components, manufacturers are able to pack more functionality into smaller devices and reduce production costs.

Question 7

A keylogger is a form of malicious code.

Accepted Answer

A keylogger is a type of malware or malicious software that records the keys struck on a keyboard, allowing an attacker to obtain sensitive information such as passwords and credit card numbers. Therefore, it is a form of malicious code.

Question 8

The term server can refer to a combination of hardware and software.

Accepted Answer

A server is typically a combination of hardware and software that provides a specific service or functionality to clients. The hardware may include a powerful computer or specialized equipment designed to handle specific tasks, while the software typically includes an operating system optimized for server use, along with specific applications or programs designed to run on the server.

Question 9

An area where data can be left on a permanent basis is memory .

Accepted Answer

storage

Question 10

A set of machine language instructions for a program is called source code.

Accepted Answer

Source code refers to the human-readable instructions written in a programming language, which are then compiled or translated into machine code instructions that a computer can understand and execute. Machine language instructions are already in binary code form and not human-readable, therefore they cannot be considered as source code.

Question 11

Free source projects promote copying, free distribution, peer review and user modifications.

Accepted Answer

Open

Question 12

A light switch is like a(n) analog device.

Accepted Answer

A light switch is a simple binary device that only has two possible states: on or off. It does not have the ability to vary its output, making it a digital device, not an analog device.

Question 13

The ALU uses registers to hold data that is being processed.

Accepted Answer

The ALU (Arithmetic Logic Unit) uses registers to temporarily hold data that is being processed before it is sent back to the main memory or to other registers.

Question 14

DIPs and PGAs are both shapes of integrated circuits.

Accepted Answer

Both DIPs (Dual In-line Packages) and PGAs (Pin Grid Arrays) are types of integrated circuit packages that differ in the physical arrangement of their pins.

Question 15

The results of statements that have been compiled are called object code.

Accepted Answer

Object code is the compiled results of source code, which can then be executed by a computer.

Question 16

In 1982, the percentages of households that had a computer was ____ percent.
A) 10
B) 30
C) 50
D) 70

Accepted Answer

The question states that the percentages of households that had a computer in 1982, and at that time computers were expensive and not commonly available for personal use. Therefore, the percentage is likely to be low and 10% is a reasonable estimate for the time period.

Question 17

Digital technology has made it easy to produce copies of music with no loss of quality from the original.

Accepted Answer

Digital technology allows for perfect replication of music without any loss in quality, making copying and sharing music files easier than ever before.

Question 18

Minicomputers were used for small businesses.

Accepted Answer

Minicomputers were first introduced in the 1960s as a smaller and cheaper alternative to mainframe computers. They were often used by small to medium-sized businesses for tasks such as accounting and inventory management.

Question 19

A mainframe computer specializes in compute-intensive problems.

Accepted Answer

Mainframe computers are designed for large-scale data processing and transaction handling, not specifically for compute-intensive problems.

Question 20

A super computer is a large and expensive computer capable of simultaneously processing data for hundreds or thousands of users.

Accepted Answer

A supercomputer is a large and expensive computer designed for high-performance computing and processing power. It is not necessarily designed to handle data for hundreds or thousands of users simultaneously, but rather for specific specialized tasks such as scientific simulations, weather forecasting, and cryptography.
