4.
A number of computers connected together to share information and hardware.
Correct Answer
B. Network
Explanation
A network is a system where multiple computers are interconnected to share information and hardware resources. It allows for communication and data sharing between different devices, enabling users to access resources and services from other computers within the network. The internet, on the other hand, is a global network of networks that connects millions of devices worldwide. RAM, or Random Access Memory, is a type of computer memory that is used for temporary storage of data and instructions that are actively being used by the computer's processor.

6.
A group of 8 bits.
Correct Answer
A. Byte
Explanation
A byte is a unit of digital information that consists of 8 bits. It is the fundamental building block of computer data storage and processing. Each bit in a byte can represent a binary value of either 0 or 1, allowing for a total of 256 possible combinations. Bytes are commonly used to measure file sizes, memory capacities, and data transfer rates.
7.
The chip which is the brains of the computer.
Correct Answer
B. Hard drive
Explanation
The hard drive is not the "brains" of the computer. The CPU (Central Processing Unit) is responsible for executing instructions and performing calculations, making it the primary component that controls the computer's operations. The hard drive, on the other hand, is a storage device used to store data, programs, and operating systems. While it plays a crucial role in storing and retrieving information, it does not have the same level of control and processing capabilities as the CPU.
8.
Which one of these is not considered a peripheral?
Correct Answer
C. CPU
Explanation
The CPU (Central Processing Unit) is not considered a peripheral because it is the main component of a computer that performs most of the processing inside the system. Peripherals, on the other hand, are external devices that connect to the CPU and provide input or output functionality, such as the keyboard and monitor.
9.
Temporary storage space on your computer.
Correct Answer
A. RAM
Explanation
RAM stands for Random Access Memory. It is a type of temporary storage space on a computer where data and instructions are stored while the computer is running. RAM allows the computer to quickly access and retrieve information that is needed by the CPU. Unlike permanent storage devices like a CD-ROM, RAM is volatile, meaning that its contents are lost when the computer is powered off or restarted. Therefore, RAM provides a fast and temporary storage solution for the computer to perform tasks efficiently.
10.
The "language of the web"
Correct Answer
C. HTML
Explanation
HTML stands for Hypertext Markup Language, which is the standard language used for creating web pages and applications. It is often referred to as the "language of the web" because it is the foundation of web development. HTML is responsible for structuring the content of a webpage, defining its layout, and linking different elements together. It allows the inclusion of text, images, videos, links, and other multimedia elements. Without HTML, the web would not exist as we know it today, making it the correct answer in this context.
