Introduction to Computer Engineering MCQs (Part-6)
What is the primary purpose of computer hardware?
A Display information
B Run software
C Provide processing power
D Store data
Computer hardware refers to the physical components of a computer system, such as the CPU, RAM, and hard drives. These components provide the necessary processing power for executing tasks and running software.
Which of the following is considered an example of software?
A Operating system
B RAM
C Keyboard
D Monitor
An operating system (OS) is software that manages hardware resources and provides an interface for users to interact with the computer. Unlike hardware, software cannot be physically touched but is essential for running programs.
What does the term “networking” refer to in computing?
A Running software applications
B Communicating between devices
C Creating websites
D Storing data remotely
Networking involves the communication and data exchange between different devices, such as computers, printers, and servers. It can be local (LAN) or global (WAN) and enables resource sharing and internet connectivity.
Which component is responsible for managing all hardware resources in a computer?
A Keyboard
B RAM
C Monitor
D Operating system
The operating system (OS) manages and coordinates all hardware resources in a computer, such as memory, processing power, and input/output devices. It also provides a user interface and runs applications.
What type of software helps a user create documents, presentations, or spreadsheets?
A Database software
B Application software
C Utility software
D System software
Application software is designed for end users to perform specific tasks, such as creating documents, presentations, or spreadsheets. Examples include Microsoft Word, Excel, and PowerPoint, which help users accomplish everyday activities.
Which of the following devices is used to enter data into a computer?
A Mouse
B Speaker
C Monitor
D Printer
A mouse is an input device that allows the user to interact with the computer by moving the cursor on the screen and selecting objects. It is one of the most common input devices.
What does the term “cloud computing” refer to?
A Running programs without an internet connection
B Storing data in local devices
C Using the internet to access remote servers
D Connecting two devices physically
Cloud computing involves accessing computing resources (like data storage and software applications) over the internet. Data is stored on remote servers rather than on local devices, allowing for flexible, scalable, and on demand usage.
Which of these is a common type of memory used in a computer system?
A Router
B RAM
C CPU
D Monitor
RAM (Random Access Memory) is a type of volatile memory used by the computer to temporarily store data and instructions that the CPU needs for processing. It is erased when the computer is turned off.
Which computer component is known as the “brain” of the computer?
A RAM
B Monitor
C Hard drive
D CPU
The CPU (Central Processing Unit) is known as the “brain” of the computer because it handles the processing and execution of instructions. It performs calculations, manages tasks, and controls the flow of information in a computer system.
What is a network switch used for?
A Manage data flow within a network
B Process data
C Connect devices to the internet
D Store data
A network switch is used to connect devices within a local area network (LAN) and manage the data traffic between them. It ensures that data is directed to the correct device efficiently within the network.
What is the role of a router in networking?
A Display information
B Store data
C Direct data packets between networks
D Manage memory
A router directs data packets between different networks, such as between a local network (LAN) and the internet (WAN). It ensures data is delivered to the correct destination based on its IP address.
Which programming language is typically used for web development?
A Java
B HTML
C Python
D C++
HTML (HyperText Markup Language) is the standard language used to create and structure content on the web. It defines elements like headings, paragraphs, links, and images on web pages, and is essential for web development.
What is the primary difference between system software and application software?
A System software is for entertainment, application software is for work
B System software runs on personal computers only
C Application software performs tasks for users
D System software manages hardware, application software performs tasks for users
System software includes operating systems and utilities that manage hardware resources, while application software includes programs designed to perform specific tasks for the user, such as word processing or web browsing.
Which of the following is an example of an output device?
A Printer
B Mouse
C Scanner
D Keyboard
A printer is an output device that produces a hard copy of digital data, such as documents or images, from a computer. It takes digital data and converts it into physical form.
What is the primary purpose of the Internet Protocol (IP)?
A Encrypt data
B Protect against malware
C Identify devices in a network
D Send emails
IP (Internet Protocol) is used to assign unique addresses to devices in a network. It enables devices to communicate with each other by identifying their locations, facilitating the routing of data across the internet.
