Introduction to Computer Engineering MCQs (Part-12)
What is the main function of an algorithm in computing?
A Solve problems
B Display results
C Store data
D Perform calculations
An algorithm is a set of step by step instructions used to solve problems or perform tasks. In computing, algorithms are essential for processing data, making decisions, and executing operations within programs efficiently.
What is the primary advantage of using cloud computing?
A Lower cost
B Increased security
C Scalability
D Faster processing
Cloud computing offers scalability, allowing users to easily adjust their storage and computing power based on demand. This flexibility ensures efficient resource use without needing to invest in physical infrastructure.
Which of these is a common characteristic of cloud computing?
A Internet based access
B Single device usage
C Local data storage
D Physical servers
Cloud computing involves storing and accessing data over the internet instead of relying on local hardware. It enables users to access software, data, and services from anywhere, making it highly flexible and convenient.
What is the primary goal of cybersecurity?
A Increase performance
B Prevent unauthorized access
C Encrypt data
D Manage networks
The primary goal of cybersecurity is to protect systems, networks, and data from unauthorized access, theft, damage, or attack. Effective cybersecurity ensures the confidentiality, integrity, and availability of information and resources.
Which of the following is a method used in cloud computing to store data remotely?
A USB flash drive
B RAM
C Cloud storage
D Hard drive
Cloud storage allows users to store data on remote servers that can be accessed over the internet. It provides flexibility, scalability, and cost efficiency compared to traditional storage devices like hard drives and USBs.
What is the function of a firewall in cybersecurity?
A Monitor traffic
B Block unauthorized access
C Encrypt data
D Store passwords
A firewall is a security device that monitors and controls incoming and outgoing network traffic. It blocks unauthorized access based on security rules, preventing threats like hacking attempts and malware from entering the network.
Which algorithmic approach is commonly used for searching data in a sorted array?
A Binary search
B Quick sort
C Merge sort
D Bubble sort
Binary search is an efficient algorithm used to find an element in a sorted array. It works by repeatedly dividing the search interval in half, which significantly reduces the number of comparisons needed compared to linear search.
What is the main benefit of cloud based applications over traditional software?
A More complex interfaces
B Offline functionality
C Accessibility from any device
D Higher cost
Cloud based applications offer the advantage of being accessible from any device with an internet connection. Unlike traditional software, which requires installation on specific devices, cloud apps allow for remote access and collaboration.
What is a key feature of algorithm complexity?
A Data encryption
B Time efficiency
C User interface
D Memory usage
Algorithm complexity refers to the time it takes for an algorithm to complete, relative to the size of the input data. Efficient algorithms minimize execution time, which is crucial for handling large data sets and improving performance.
Which of these is an essential aspect of cybersecurity awareness?
A Recognizing phishing attempts
B Designing hardware
C Writing code
D Managing networks
Cybersecurity awareness includes educating individuals about recognizing phishing attempts, which are fraudulent attempts to steal sensitive information like passwords and credit card numbers. Awareness helps prevent cyberattacks and secures personal and organizational data.
What is a common use case for cloud computing in businesses?
A Running applications
B Local data storage
C Developing hardware
D Printing documents
In businesses, cloud computing is commonly used for running applications like customer relationship management (CRM) systems, enterprise resource planning (ERP) software, and other business critical tools. This allows for greater flexibility and cost savings.
Which of the following is a type of system software used in cloud computing?
A Operating system
B Web browser
C Word processor
D Email client
System software, such as the operating system, is essential for cloud computing. The OS manages cloud resources, provides a user interface, and enables the operation of cloud applications and services, making it a vital part of the infrastructure.
What is a key advantage of using encryption in cybersecurity?
A Increase processing speed
B Prevent data loss
C Protect sensitive data
D Improve hardware performance
Encryption is used in cybersecurity to protect sensitive data by converting it into an unreadable format that can only be accessed with a decryption key. It ensures data confidentiality during transmission or storage, even in the event of a breach.
Which type of cloud computing service provides virtualized computing resources over the internet?
A DaaS
B SaaS
C IaaS
D PaaS
IaaS (Infrastructure as a Service) provides virtualized computing resources over the internet. This includes virtual machines, storage, and networking, allowing businesses to rent hardware infrastructure and manage applications without owning physical servers.
What is a core principle of algorithm design?
A Ensuring user interface
B Optimizing performance
C Minimizing memory usage
D Maximizing time complexity
A core principle of algorithm design is optimizing performance. This involves creating algorithms that solve problems efficiently, utilizing the least resources, minimizing execution time, and ensuring they scale well with increasing input sizes.
