How Well Do You Know Parts Of The Computer? Quiz #2

Explanation
The given statement is incorrect. A computer is a motorized device that processes input into output, not the other way around. The input can be in the form of data or instructions, which the computer processes and provides output in the form of results or actions. Therefore, the correct answer is False.

Explanation
The correct answer is Central Processing Unit. The CPU, or Central Processing Unit, is the primary component of a computer that performs most of the processing inside the computer. It interprets and executes instructions from the computer's memory, performs arithmetic and logical operations, and controls the input and output devices. The CPU is often referred to as the "brain" of the computer, as it carries out the majority of the computer's tasks and operations.

Explanation
This statement is true because a memory is indeed composed of electronic components that store instructions, data, and other information. These components include transistors, capacitors, and other semiconductor devices that can retain and retrieve data. These stored instructions are then executed by the computer's processor. Therefore, the given statement accurately describes the nature of a memory in a computer system.

Explanation
An output device is a peripheral device that is used to display or provide information to the user. A printer is an output device because it takes electronic data from a computer and generates a hard copy of that data on paper. It is used to produce physical copies of documents, images, or other types of information. Therefore, printer is the correct answer as it fits the definition of an output device.

Explanation
The given statement is false. In reality, a hard disk provides much greater storage capacity than a floppy disk. Floppy disks were commonly used in the past but had limited storage capacity, typically ranging from 1.44 MB to 2.88 MB. On the other hand, hard disks can store much larger amounts of data, usually starting from several gigabytes and going up to several terabytes. Therefore, the statement that floppy disks provide greater storage capacity than a hard disk is incorrect.

Explanation
Communication is an advantage in using computers because they allow people to easily connect and interact with others, regardless of geographical distance. Computers enable instant messaging, video calls, and email, which facilitate efficient and effective communication. This advantage can enhance collaboration, productivity, and knowledge sharing among individuals and organizations.

Explanation
CD stands for Compact Disc. It is a digital optical disc used for storing and playing audio, video, and other data. The term "Compact" refers to its smaller size compared to traditional vinyl records, while "Disc" refers to its disc-shaped form. Compact discs revolutionized the music industry by providing a more durable and portable medium for music storage. They became popular in the 1980s and 1990s and are still used today, although digital streaming has largely replaced physical media.

Explanation
The brain of the computer is the Central Processing Unit (CPU). It is responsible for executing instructions, performing calculations, and controlling the overall operation of the computer. The CPU is often referred to as the brain because it is the most important component that processes data and carries out tasks. It is responsible for coordinating and managing all the other hardware and software components of the computer system.

Explanation
The question is asking which of the given options is capable of producing sound. Without the options provided, it is impossible to determine the correct answer.

Explanation
Voice recognition technology is used to convert spoken language into written text. This allows users to interact with devices and applications using their voice. Voice input can be accepted by various devices and applications such as smartphones, smart speakers, virtual assistants, and voice recognition software. These technologies use algorithms to analyze and interpret the spoken words, converting them into text that can be processed and understood by the device or application.

Explanation
The device that you will use for online chatting is a computer or a smartphone. These devices have internet connectivity and support various messaging applications or platforms that allow you to chat with others online. They provide a convenient and accessible means of communication for chatting with friends, family, or colleagues over the internet.

Explanation
The question is asking for a device that is not a storage device. A storage device is a hardware device used to store and retrieve digital information. The options provided are "hard drive," "USB flash drive," "keyboard," and "CD-ROM." Both the hard drive and USB flash drive are storage devices as they are used to store and retrieve digital information. The keyboard is an input device used to enter data into a computer, not a storage device. The CD-ROM is also a storage device as it is used to read and store data on a compact disc. Therefore, the correct answer is "keyboard."

Explanation
The statement claims that computers do not have any disadvantages. However, this is not true. While computers offer numerous benefits such as solving problems and making work easier, they also have disadvantages. Some common disadvantages include potential health issues like eye strain and sedentary lifestyle, the risk of cyber threats and data breaches, and the potential for addiction or over-reliance on technology. Therefore, the correct answer is false.

Explanation
Compact discs (CDs) do indeed provide lesser storage capacity than Digital Versatile Discs (DVDs). This is because CDs typically have a storage capacity of around 700 megabytes, while DVDs can hold up to 4.7 gigabytes or more. This difference in storage capacity allows DVDs to store larger files, such as high-definition movies or video games, compared to CDs. Therefore, the statement is true.
