Class 1 Computer Chapter 1 Computer.....My Friend

Explanation
The given statement states that "_____ is a smart machine." The only option provided that fits this statement is "Computer." Computers are considered smart machines because they can perform complex tasks, process information, and make decisions based on programmed instructions or artificial intelligence algorithms. They are designed to mimic human intelligence and can perform various functions such as calculations, data processing, communication, and problem-solving. Therefore, the correct answer is "Computer."

Explanation
Computers are commonly seen in schools as they are widely used for educational purposes. They are used for various activities such as research, learning software, online assignments, and communication. Schools often have computer labs or classrooms equipped with computers to facilitate learning and enhance students' digital literacy skills. Therefore, the correct answer is "School."

Explanation
The correct answer is "Machine" because computers are electronic devices that are designed to perform various tasks and calculations automatically. They are programmed to execute specific instructions and can process large amounts of data quickly and accurately. Unlike human beings, computers do not possess consciousness or emotions, and they operate based on logical algorithms and binary code. Therefore, the term "Machine" accurately describes computers.

Explanation
Among the given options, the desktop computer is the largest in size. Mobile devices such as smartphones are typically smaller and more compact, while laptops are larger than smartphones but still more portable. On the other hand, desktop computers are larger and bulkier, often requiring a dedicated space on a desk or table. Therefore, the correct answer is "Desktop Computer."

Explanation
A laptop is a computer that is portable and can be easily carried from one place to another. Unlike desktop computers, which are stationary and usually require a fixed location to operate, laptops are designed to be lightweight and compact, allowing users to take them on the go. Laptops typically have a built-in screen, keyboard, and trackpad, making them convenient for use in various settings such as coffee shops, classrooms, or during travel.

Explanation
The correct answer is "Desk" because desktop computers are designed to be placed on a desk. The term "desktop" refers to the physical location where the computer is typically used, distinguishing it from other types of computers like laptops or tablets that are designed for portable use. Placing a desktop computer on a desk provides a stable and ergonomic workspace for the user.

Explanation
A computer runs on electricity as it requires electrical power to operate its components such as the processor, memory, and storage devices. Electricity is essential for powering the computer's circuits and providing the necessary energy for the computer to perform tasks and functions. Without electricity, a computer would not be able to function or carry out any operations.

Explanation
A computer is a machine that can perform multiple tasks simultaneously. It is designed to process and execute commands and instructions from users or software programs. Unlike other machines like a refrigerator, which typically perform a single function, a computer is capable of multitasking, allowing users to run multiple applications, browse the internet, listen to music, and perform various other tasks simultaneously. Therefore, a computer fits the description of a machine that can do many things at a time.

Explanation
Computers need human beings to decide what to do. This is because computers are programmed by humans to perform specific tasks and make decisions based on the instructions provided. Without human intervention, computers would not be able to function autonomously or make independent decisions. Human beings are responsible for providing the necessary input and guidance to computers, enabling them to perform tasks and make decisions effectively.

Explanation
The given sentence states that you can play something on the computer. The only option that makes sense in this context is "Video Games" as it is a common activity to play video games on a computer. Kabaddi, on the other hand, is a physical sport that cannot be played on a computer. Therefore, the correct answer is Video Games.

Explanation
The given question is asking what can be watched on a computer. The correct answer is "Movies" because movies can be streamed or downloaded and watched on a computer.

Explanation
The given question is asking for activities that can be done on a computer. Both drawing and sketching can be done on a computer using various software programs and digital tools. Therefore, the correct answer is "Draw".

Explanation
Computers do not get tired after working long hours because they do not have physical bodies or emotions like human beings. They are machines designed to perform tasks efficiently and consistently without experiencing fatigue or exhaustion. Unlike humans, computers can operate continuously without the need for rest or breaks, making them ideal for tasks that require long periods of uninterrupted work.

Explanation
Computers are programmed to perform tasks with precision and accuracy. They follow specific instructions and algorithms, which eliminates the possibility of making mistakes due to human error or oversight. On the other hand, human beings are prone to making mistakes due to factors like fatigue, distraction, or lack of knowledge. While humans can learn from their mistakes and improve, computers consistently execute tasks without errors when programmed correctly. Therefore, the statement "Computers never make mistakes" is justified.

Explanation
Human beings cannot remember lots of information for a long time because our memory capacity is limited. Unlike computers, which can store vast amounts of data and retrieve it quickly, our brains have a finite capacity for storing information. Additionally, human memory is prone to forgetting over time, as memories can fade or become distorted. While some information can be retained for a long time with conscious effort and repetition, the ability to remember large amounts of information indefinitely is a challenge for human beings.

Explanation
A computer is a versatile device that can be used for various purposes such as performing calculations, writing letters, playing games, listening to music, and watching movies. It has a wide range of functionalities and can handle multiple tasks simultaneously. With its processing power and storage capacity, a computer provides the necessary resources to support these activities efficiently.

Explanation
The correct answer is "Desktop Computer" because the picture represents a computer that is designed to be placed on a desk or table, with a separate monitor, keyboard, and mouse. It is not a laptop, which is a portable computer that can be used on a person's lap or easily carried around.

Explanation
The correct answer is "Laptop." The picture given below shows a device that is portable and compact, which is characteristic of a laptop. It has a keyboard and a screen attached, making it suitable for personal use. A desktop, on the other hand, is a computer system that consists of a separate tower unit and a monitor. Therefore, the picture clearly represents a laptop.

Explanation
The correct answer is "Calculator" because the picture represents a device with number buttons and a display screen, which is typically found on a calculator. The other options, "Laptop" and "Tablet," do not match the features of the picture.
