How Well Do You Know Hardware & Software 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. Input refers to the data or instructions that are entered into the computer, while output refers to the results or information that the computer produces.

Explanation
The correct answer is "Central Processing Unit." CPU stands for Central Processing Unit, which is the main component of a computer that performs most of the processing inside the computer. It is responsible for executing instructions, performing calculations, and managing data flow between different parts of the computer. The CPU acts as the brain of the computer, coordinating and controlling all the functions of the computer system. Control Processing Unit, Central Protocol Unit, and Control Produce Unity are not correct terms for CPU.

Explanation
The statement is true because memory in a computer system is composed of electronic components, such as transistors and capacitors, that are used to store data and instructions. These components retain information even when power is turned off, allowing the computer to retrieve and execute instructions when needed. Therefore, it is accurate to say that memory stores instructions waiting to be executed.

Explanation
An output device is a device that is used to display or present data or information. A printer is an output device because it is used to produce hard copies of documents or images. It takes electronic data and transfers it onto physical paper, making it a suitable choice for an output device.

Explanation
This statement is false. Floppy disks do not provide greater storage capacity than a hard disk. In fact, floppy disks have a much smaller storage capacity compared to hard disks. Floppy disks typically have a storage capacity of only a few megabytes, while hard disks can store several terabytes of data. Therefore, the correct answer is false.

Explanation
Communication is an advantage in using computers because it allows individuals to connect and interact with others easily and efficiently. Computers enable communication through various means such as email, instant messaging, video calls, and social media platforms. This facilitates faster and more convenient communication, breaking down barriers of distance and time. It also enables collaboration and sharing of information, enhancing productivity and efficiency in various personal and professional settings.

Explanation
CD stands for Compact Disc. A compact disc is a digital optical disc used to store and playback audio, video, and other data. It is a widely used medium for distributing music, movies, software, and other digital content. The term "compact" refers to its smaller size compared to traditional vinyl records or cassette tapes. Therefore, the correct answer is Compact disc.

Explanation
The brain of the computer is the Central Processing Unit (CPU). It is responsible for executing instructions, performing calculations, and managing the overall operation of the computer system. The CPU acts as the control unit and coordinates the activities of all the other hardware components, including memory, input/output devices, and storage. It processes data and instructions by fetching them from memory, decoding them, executing the required operations, and storing the results. The CPU is often referred to as the brain of the computer because it performs the essential tasks necessary for the computer to function.

Explanation
Sound is produced by vibrating objects. The options given are a guitar, a painting, and a cloud. Out of these options, a guitar is the only object that can vibrate and produce sound. A painting and a cloud are not capable of vibrating and therefore cannot produce sound.

Explanation
The correct answer to the question is "Virtual assistant". Virtual assistants like Siri, Google Assistant, and Amazon Alexa are designed to accept voice input from users. These virtual assistants use speech recognition technology to understand and respond to voice commands and queries. They can perform various tasks, such as setting reminders, answering questions, playing music, and controlling smart home devices, all through voice interaction.

Explanation
For online chatting, the most suitable device to use would be a smartphone or a computer. These devices provide easy access to various messaging applications and platforms, allowing users to communicate with others in real-time. Additionally, smartphones and computers offer a larger screen size and a more comfortable typing experience compared to other devices like tablets or smartwatches.

Explanation
The question is asking for a device that is not a storage device. A storage device is a hardware device used to store data, such as a hard drive, solid-state drive, or USB flash drive. Therefore, any option that is not a storage device would be the correct answer.

Explanation
The statement in the question claims that computers do not have any disadvantages. However, this is not true. While computers do provide solutions to problems and make work easier and more convenient, they also have disadvantages. Some of these disadvantages include the potential for addiction, loss of privacy, and negative impact on physical health due to prolonged sitting and eye strain. Therefore, the correct answer is false.

Explanation
Compact discs (CDs) indeed provide lesser storage capacity than Digital Versatile Discs (DVDs). CDs typically have a storage capacity of around 700 MB to 1.4 GB, while DVDs can store up to 4.7 GB to 9 GB of data. This is due to the difference in physical size and technology used in the construction of CDs and DVDs. Therefore, the statement "Compact discs (CDs) provides lesser storage capacity than Digital Versatile Discs (DVDs)" is true.
