Introduction to Computer Engineering MCQs (Part-4)
What is a personal computer primarily designed for?
A Everyday use
B Internet browsing
C Scientific calculations
D Large-scale processing
A personal computer (PC) is designed for general, everyday tasks like word processing, internet browsing, and light gaming. It is typically used by individuals at home or in offices for personal work and entertainment.
What does “Computer Engineering” focus on?
A Network security
B Hardware design
C Software and hardware
D Software development
Computer Engineering is a field that focuses on both hardware design and software development. It bridges the gap between computer science and electrical engineering by integrating these disciplines to create efficient computer systems.
What type of computer is used in research institutions for complex calculations?
A Mainframe
B Supercomputer
C Workstation
D Personal computer
Supercomputers are designed to perform highly complex calculations and simulations at extremely high speeds. They are used in research fields like climate modeling, physics, and artificial intelligence, requiring immense computational power.
Which computer type is known for handling large-scale data processing for businesses?
A Server
B Personal computer
C Supercomputer
D Mainframe
Mainframe computers are designed to handle and process large amounts of data quickly. They are typically used by large organizations for bulk data processing, such as in banking, insurance, and government operations.
Which of these is the main difference between Computer Engineering and Computer Science?
A Computer science focuses only on hardware
B Computer engineering deals with hardware and software
C Computer science focuses on network security
D Computer engineering focuses on programming only
Computer Engineering integrates electrical engineering and computer science to design both hardware (like microprocessors) and software systems. Computer Science focuses more on the theoretical aspects of computing, including algorithms and programming.
What does a microprocessor do in a computer?
A Perform calculations
B Manage memory
C Store data
D Control hardware
A microprocessor is the central unit in a computer that performs arithmetic calculations, logic operations, and executes instructions. It is often referred to as the “brain” of the computer, driving its functions.
What is an embedded system typically used for?
A General-purpose computing
B Running operating systems
C Software development
D Performing dedicated functions
Embedded systems are specialized computing systems that perform dedicated functions within a larger device. Examples include systems in cars, washing machines, and medical devices, where the system’s role is to control or monitor specific tasks.
What is the key advantage of using digital systems over analog systems?
A Digital systems consume less power
B Analog systems are cheaper
C Digital systems are more accurate
D Digital systems are easier to design
Digital systems provide greater accuracy in processing data as they use discrete values (binary). Unlike analog systems, which process continuous data and can be more prone to errors, digital systems are more reliable and precise.
What is a key feature of a computer network?
A Programming languages
B Connecting devices
C Operating systems
D Power management
A computer network connects multiple devices such as computers, printers, and servers to share resources and data. It enables communication between devices, either locally or over the internet, facilitating data transfer and resource sharing.
What does a router do in a computer network?
A Forward data packets
B Store data
C Connect devices
D Process data
A router is a networking device that forwards data packets between different networks, such as local networks and the internet. It ensures that data is sent to the correct destination based on the address information in the packet.
What is the primary purpose of an algorithm in computer programming?
A Compile programs
B Create graphics
C Solve a problem
D Perform calculations
An algorithm is a step-by-step procedure used to solve a problem or perform a task. In computer programming, algorithms are essential for defining the logic and flow of a program to ensure it functions correctly.
Which programming language is most commonly used for system-level programming?
A Ruby
B C
C Python
D Java
The C programming language is widely used for system-level programming because it offers low-level access to memory and hardware. It is used to write operating systems, device drivers, and other performance-critical software.
What is cloud computing primarily used for?
A Offline applications
B Local networking
C Web browsing
D Data storage and processing
Cloud computing enables remote storage, management, and processing of data over the internet. It allows users to access computing resources such as storage and processing power on-demand, without needing to own physical hardware.
What is the key feature of application software?
A Performs specific tasks
B Controls network traffic
C Provides security
D Manages hardware resources
Application software is designed to help users perform specific tasks, such as word processing, web browsing, and data analysis. Unlike system software, which manages hardware, application software focuses on user productivity.
What does Boolean algebra use in computing?
A String manipulation
B Decimal numbers
C Logical operations
D Floating-point operations
Boolean algebra deals with logical operations and binary values (true/false, 1/0). It is foundational in digital circuit design and programming logic, enabling computers to make decisions based on true/false conditions.
