### An electronic device that receives data, processes data, stores data, and produces a result is a...

• A.

Modem

• B.

Network

• C.

Monitor

• D.

Computer

D. Computer
Explanation
A computer is an electronic device that is capable of receiving data, processing it, storing it, and producing a result. It is a versatile device that can perform a wide range of tasks, from simple calculations to complex simulations. It consists of various components such as a central processing unit (CPU), memory, storage devices, and input/output devices. The modem is a device that allows computers to connect to the internet, the network is a collection of interconnected devices, and the monitor is an output device that displays visual information. Therefore, the correct answer is computer.

### The system in which computers communicate and/or share/save information with 2 digits (1 and 0) is called:

• A.

Solar System

• B.

Cardiovascular System

• C.

Bowflex System

• D.

Binary System

D. Binary System
Explanation
The correct answer is Binary System. This system is based on the use of two digits, 1 and 0, to represent information in computers. It is the foundation of all digital technology and is used in computer programming, data storage, and communication. The term "binary" refers to the fact that it uses a base-2 numeral system, as opposed to the decimal system which uses a base-10 numeral system. In the binary system, each digit represents a power of 2, allowing for efficient representation and manipulation of data in electronic devices.

### Which of the following are reasons for using a computer?

• A.

Speed

• B.

Error Free Calculations

• C.

Storage

• D.

All of the above

D. All of the above
Explanation
Computers are used for various reasons, including speed, error-free calculations, and storage. They can perform tasks much faster than humans, making them ideal for complex calculations and data processing. Additionally, computers are known for their accuracy, reducing the chances of errors in calculations. Furthermore, computers offer vast storage capabilities, allowing users to store and access large amounts of data efficiently. Therefore, all of the given options - speed, error-free calculations, and storage - are valid reasons for using a computer.

### To a computer: An tangible piece of equipment that can be seen and touched is called?

• A.

Software

• B.

Hardware

• C.

Shareware

• D.

Freeware

B. Hardware
Explanation
Hardware refers to the physical components of a computer system that can be seen and touched. This includes devices such as the monitor, keyboard, mouse, and central processing unit (CPU). Software, on the other hand, refers to the programs and instructions that run on the hardware. Shareware and freeware are types of software that can be downloaded and used for free or with limited functionality. Therefore, the correct answer is hardware as it specifically refers to tangible computer equipment.

• A.

Personal Computers

• B.

Supercomputers

• C.

Mainframes

• D.

Nanocomputers

C. Mainframes
Explanation
Large computers that are often used by businesses and governments to process large amounts of data are called mainframes. Mainframes are specifically designed to handle heavy workloads and have high processing power and storage capacity. They are capable of executing multiple tasks simultaneously and are known for their reliability, security, and scalability. Mainframes are typically used for critical applications such as financial transactions, scientific research, and data analysis, where the processing of massive amounts of data is required.
