What does RAM stand for in computing?
-
Random Application Memory
-
Read-Access Memory
-
Random Access Memory
-
Read-Only Memory
Correct Answer
A. Random Access MemoryExplanation
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.Rate this question:

What type of software allows users to create documents, spreadsheets, and presentations?
-
Database
-
Antivirus
-
Office Suite
-
Graphics Software
Correct Answer
A. Office SuiteExplanation
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.Rate this question:

Which component is responsible for storing data permanently in a computer?
-
CPU
-
RAM
-
Hard Drive
-
Power Supply
Correct Answer
A. Hard DriveExplanation
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.Rate this question:

Which cable is typically used to connect a computer to a local network?
-
HDMI
-
USB
-
Ethernet
-
VGA
Correct Answer
A. EthernetExplanation
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.Rate this question:

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 systemExplanation
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.Rate this question:

Which type of software is designed to protect against malicious software?
-
Firewall
-
Antivirus
-
Browser
-
Operating System
Correct Answer
A. AntivirusExplanation
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.Rate this question:

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 AddressExplanation
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.Rate this question:
