1What is the primary role of the Central Processing Unit (CPU) in a computer system?
A.Execute program instructions and perform calculations
B.Store long-term user files permanently
C.Provide wireless internet access only
D.Convert paper documents into editable text automatically
Explanation: The CPU fetches, decodes, and executes instructions and performs arithmetic/logic operations. Long-term storage, networking, and OCR are handled by other components or software.
2Which memory type is typically used as high-speed temporary working memory while programs run?
A.ROM
B.RAM
C.Optical disc
D.Magnetic tape archive
Explanation: RAM holds active programs and data for the CPU. ROM stores firmware; optical discs and tape are secondary or archival storage.
3Which of the following is system software rather than application software?
A.Spreadsheet package for budgeting
B.Word processor for reports
C.Operating system that manages hardware and processes
D.Presentation tool for client demos
Explanation: An operating system is system software that manages hardware, processes, and memory and provides services for applications. Word, spreadsheet, and presentation tools are application software.
4Using the common binary storage ladder taught in school IT, 1 gigabyte (GB) equals:
A.1,024 kilobytes (KB)
B.1,024 bits
C.1,024 terabytes (TB)
D.1,024 megabytes (MB)
Explanation: Commonly taught: 1 KB = 1,024 bytes, 1 MB = 1,024 KB, 1 GB = 1,024 MB, 1 TB = 1,024 GB. Decimal SI marketing units differ slightly, but vocational curricula usually use the 1,024-based ladder.
5Which component permanently stores the firmware that helps start (boot) the computer?
A.ROM/UEFI firmware storage on the motherboard
B.RAM only
C.CPU cache only
D.Printer buffer
Explanation: Boot firmware (BIOS/UEFI) is stored in non-volatile ROM/flash on the motherboard. RAM and cache are volatile working storage; a printer buffer is unrelated to PC boot firmware.
6In the IPO model of computing, Input–Process–Output means:
A.Only cloud, only storage, only power
B.Data entered into the system, operations performed on that data, and results produced
C.Only hardware, only software, only networks
D.Only viruses, only backups, only updates
Explanation: The IPO model describes computing as taking input, processing it according to instructions, and producing output (screen, print, file, network response, etc.).
7Which statement best distinguishes primary memory from secondary storage?
A.Primary memory is always slower and larger than secondary storage
B.Secondary storage only exists inside the CPU
C.Primary memory is typically used for active work and is often volatile; secondary storage holds data long-term and is non-volatile
D.Primary memory cannot be measured in bytes
Explanation: Primary memory (e.g., RAM) supports active processing and is usually volatile. Secondary storage (HDD/SSD/USB) retains data without power for long-term use.
8What does a device driver primarily do?
A.Replace the need for an operating system
B.Compress all user documents automatically
C.Block all internet traffic by default
D.Enable the OS and applications to communicate correctly with a specific hardware device
Explanation: A device driver translates OS/application requests into commands the hardware understands so printers, NICs, GPUs, and other devices work correctly.
9Which best describes open-source software in an ITeS workplace context?
A.Software whose source code is available under a license that may allow study, modification, and redistribution under stated terms
B.Software that can never be used commercially
C.Software that requires no license of any kind forever
D.Any free mobile game
Explanation: Open-source software publishes source code under licenses (for example GPL, MIT, Apache) that define rights to use, modify, and redistribute. Commercial use may be allowed; license terms still apply.
10In binary place values, what decimal value does the bit pattern 1010 represent?
A.8
B.10
C.12
D.15
Explanation: Binary 1010 = 1×8 + 0×4 + 1×2 + 0×1 = 10 in decimal. Binary place values are foundational for computer fundamentals.
