Y3: Computer Systems 1

What is a computer system made up of?

• Only hardware components

• Only software components

• Both hardware and software components

• None of the above

Answer explanation

A computer system is made up of hardware and software components. The hardware components include physical devices such as the central processing unit (CPU), memory, storage devices, input devices (e.g., keyboard, mouse), output devices (e.g., monitor, printer), and other peripherals (e.g., scanner, webcam). The software components include the operating system and other applications that run on the system, as well as any programs and files stored on the system. Together, the hardware and software components work together to form a functioning computer system that can perform a wide range of tasks and operations.

What is the difference between hardware and software?

• Hardware is physical, while software is not

• Software is physical, while hardware is not

• Both hardware and software are physical

• . None of the above

Answer explanation

In simple terms, hardware is the physical equipment that you can touch and see, while software is the programs and instructions that run on the hardware to make it perform specific tasks.

Which of the following is an input device?

• Speaker

• Mouse

• Printer

• Monitor

Answer explanation

Input devices allow us to communicate with a computer system by providing data or instructions that the computer can use to perform specific tasks.

What types of files can be stored on a computer's hard drive?

• text

• audio

• video

• images

• all of the above

Answer explanation

A computer's hard drive is a type of storage device that is used to store files and data on a computer system. There are different types of files that can be stored on a computer's hard drive, including:

Text files

Audio files

Video files

Game files

When you save a file to your computer's hard drive, it is stored on the disk and can be accessed later. This allows you to store and organize different types of files on your computer for easy access and use.

What can computers be programmed to do?

• Control machines and physical objects

• Store Files

• Perform calculations

• Analyze Data

• All of the Above

Answer explanation

Computers can be programmed to perform many different tasks and operations. A program is a set of instructions that tells the computer what to do. When you run a program on a computer, it performs the operations that are specified in the program.

Which of the following is an output device?

• Printer

• Scanner

• Keyboard

• Mouse

• Stylus Pen

Answer explanation

An output device is a type of hardware component that allows a computer to communicate information back to the user. Examples of output devices include a monitor, a printer, or a speaker.

What is the Internet of Things (IoT)?

• A type of computer virus that infects smart devices.

• A new type of social media platform

• A virtual reality platform for gaming

• A system of physical objects that are connected to the internet and can communicate with each other.

• A global network of interconnected computers and servers

Answer explanation

The Internet of Things (IoT) refers to the network of physical objects or "things" that are embedded with sensors, software, and connectivity to the internet, allowing them to collect and exchange data. These objects can be anything from household appliances and wearables to vehicles and industrial machinery. The IoT enables these objects to communicate with each other and with other devices and systems over the internet, creating a network of connected devices that can be monitored, controlled, and optimized remotely.

What are some common 'Internet of Things' devices?

• Cars and airplanes

• Toys and Books

• Phones and tablets

• Smart speakers and smart thermostats

Answer explanation

Smart speakers and smart thermostats are considered part of the "Internet of Things" (IoT) because they are designed to be connected to the internet and can communicate with other devices and services online. They use sensors and other technologies to collect data and perform various functions, such as playing music or adjusting the temperature in a room.

On the other hand, tablets and planes are not typically considered part of the IoT because they are not primarily designed to be connected to the internet and do not have the same kind of sensor or communication capabilities as smart speakers or smart thermostats.

Which of the following is an input device?

• Projector

• Printer

• Speaker

• Microphone

• Headphones

What is an Operating System?

• A type of software that controls hardware components of a computer system.

• A type of computer virus that infects the operating system.

• A physical component of a computer system that performs computations.

• A type of network that connects multiple computers together.

• A type of computer language used to create software applications

Answer explanation

An operating system (OS) is a software program that manages and controls the basic functions of a computer system, such as managing hardware resources, providing a user interface, and running applications. It is the most important type of system software that runs on a computer system. The operating system acts as an intermediary between the hardware components and software applications, allowing them to communicate with each other and use system resources efficiently. Some common examples of operating systems include Windows, macOS, Linux, iOS, and Android.
