    What does CPU stand for in computing?

    • Central Processing Unit

    • Computer Processing Unit

    • Central Power Unit

    • Core Processing Unit

    Correct Answer
    A. Central Processing Unit
    Explanation
    CPU stands for Central Processing Unit. It is often referred to as the brain of the computer because it executes instructions from software programs and processes data to perform tasks. The CPU consists of multiple cores that can execute instructions simultaneously, enhancing computational speed. Clock speed, measured in gigahertz (GHz), determines how fast the CPU can process instructions per second. Higher clock speeds indicate faster processing capabilities, crucial for tasks requiring complex calculations or multitasking. The CPU's efficiency directly impacts overall system performance, making it a critical component in modern computing devices.

    What type of software allows users to create documents, spreadsheets, and presentations?

    • Database

    • Antivirus

    • Office Suite

    • Graphics Software

    Correct Answer
    A. Office Suite
    Explanation
    An office suite software allows users to create documents, spreadsheets, and presentations. It typically includes applications like word processors (e.g., Microsoft Word), spreadsheet programs (e.g., Microsoft Excel), and presentation software (e.g., Microsoft PowerPoint). Office suites provide essential tools for document creation, data analysis, and visual communication, supporting various business, academic, and personal tasks. They offer features such as formatting options, data manipulation tools, and collaboration capabilities to enhance productivity and efficiency in managing digital information. Office suite software is integral to modern computing environments, empowering users to create, edit, and share content effectively across different platforms and devices.

    What does RAM stand for in computing?

    • Random Application Memory

    • Read-Access Memory

    • Random Access Memory

    • Read-Only Memory

    Correct Answer
    A. Random Access Memory
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. This makes RAM essential for fast data processing because it enables quick read and write operations. RAM temporarily stores data that the CPU needs to access quickly, such as running applications and operating system tasks. Its speed is measured in nanoseconds (ns), indicating how quickly data can be retrieved and processed, crucial for overall system performance.

    Which component is responsible for storing data permanently in a computer?

    • CPU

    • RAM

    • Hard Drive

    • Power Supply

    Correct Answer
    A. Hard Drive
    Explanation
    A hard drive is responsible for storing data permanently in a computer. Unlike RAM, which is volatile and loses data when powered off, a hard drive uses magnetic storage to retain data even when the computer is turned off. Hard drives have large capacities and are used for long-term storage of operating systems, applications, documents, and media files. Their capacity is measured in gigabytes (GB) or terabytes (TB), indicating how much data they can hold. This permanent storage capability makes hard drives essential for preserving data integrity and accessibility over extended periods.

    Which cable is typically used to connect a computer to a local network?

    • HDMI

    • USB

    • Ethernet

    • VGA

    Correct Answer
    A. Ethernet
    Explanation
    An Ethernet cable is typically used to connect a computer to a local network, such as a home or office network. It enables high-speed data transmission between devices within the network, supporting activities like file sharing, internet access, and network printing. Ethernet cables use twisted pairs of copper wires to minimize interference and maximize data integrity over distances ranging from a few meters to hundreds of meters. Their reliability and scalability make Ethernet cables a standard choice for establishing wired network connections, providing stable and consistent data transfer rates essential for modern networking applications.

    Which operating system is developed by Apple In?

    • Windows

    • Linux

    • MacOS

    • Android

    Correct Answer
    A. MacOS
    Explanation
    macOS is an operating system developed by Apple Inc. It is designed specifically for Apple Macintosh computers and offers a user-friendly interface, advanced graphics capabilities, and seamless integration with Apple's ecosystem of software and services. macOS is known for its stability, security features, and optimized performance on Mac hardware, providing users with a reliable platform for productivity, creativity, and entertainment. It supports a wide range of applications, including those developed by Apple and third-party developers, making it a preferred choice for professionals and enthusiasts seeking a robust computing experience tailored to Mac devices.

    Which type of software is designed to protect against malicious software?

    • Firewall

    • Antivirus

    • Browser

    • Operating System

    Correct Answer
    A. Antivirus
    Explanation
    Antivirus software is designed to protect against malicious software, also known as malware. It detects, prevents, and removes viruses, worms, trojans, and other types of malicious programs that can harm computer systems or compromise data security. Antivirus software uses signature-based detection and heuristic analysis to identify and neutralize threats before they can cause damage. It continuously monitors system activity, scans files and downloads, and updates virus definitions to stay ahead of new and evolving threats. Effective antivirus protection is essential for maintaining system integrity and safeguarding sensitive information from cyber threats.

    What is the purpose of BIOS in a computer system?

    • Manage network connections

    • Control peripheral devices

    • Boot the operating system

    • Manage file storage

    Correct Answer
    A. Boot the operating system
    Explanation
    BIOS stands for Basic Input/Output System. It is firmware embedded in a computer's motherboard that initializes hardware components and facilitates the boot process when the computer is turned on. BIOS performs essential tasks such as conducting a Power-On Self Test (POST), identifying and initializing hardware devices like the CPU, RAM, and hard drive, and loading the operating system into memory. It also provides a configuration interface, known as BIOS setup or CMOS setup, where users can adjust system settings, manage hardware parameters, and troubleshoot startup issues. BIOS plays a critical role in ensuring hardware compatibility and system stability during the computer's startup sequence.

    What does IP address stand for in networking?

    • Internet Protocol Address

    • Internal Protocol Address

    • Internet Provider Address

    • Integrated Protocol Address

    Correct Answer
    A. Internet Protocol Address
    Explanation
    IP address stands for Internet Protocol Address. It is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. IP addresses facilitate the identification and location of devices within a network, enabling data routing and communication across the internet. An IP address consists of four sets of numbers separated by periods (e.g., 192.168.1.1), with each set ranging from 0 to 255. IP addresses can be dynamic or static, assigned automatically by a DHCP server or manually configured, respectively, to ensure efficient network management and connectivity.
