1Which component of the Central Processing Unit (CPU) is responsible for performing arithmetic operations such as addition and logical operations such as comparisons?
A.Arithmetic Logic Unit (ALU)
B.Control Unit (CU)
C.Register Array
D.Cache Memory
Explanation: The Arithmetic Logic Unit (ALU) is the CPU component that performs all mathematical calculations (addition, subtraction, multiplication) and logical comparisons (equal to, greater than, less than). The Control Unit coordinates flow of data, Registers hold temporary data, and Cache holds frequently accessed data.
2What is the primary difference between Random Access Memory (RAM) and Read-Only Memory (ROM)?
A.RAM is volatile and temporary, whereas ROM is non-volatile and permanent.
B.RAM is read-only, whereas ROM is rewritable by application software.
C.RAM holds startup firmware, whereas ROM stores running user programs.
D.RAM is located on the motherboard, whereas ROM is always external.
Explanation: RAM is volatile memory, meaning its contents are lost when the computer is powered off. ROM is non-volatile memory, designed to permanently store startup instructions (firmware) that persist even without power.
3Which of the following devices is classified strictly as an input device?
A.Flatbed Scanner
B.Inkjet Printer
C.LCD Monitor
D.Active Speaker
Explanation: A flatbed scanner is strictly an input device because it converts physical images or text documents into digital data sent to the computer. Printers, monitors, and speakers are all output devices that display or project data from the computer to the user.
4Why is a Solid State Drive (SSD) generally preferred over a traditional Hard Disk Drive (HDD) for secondary storage in modern laptops?
A.SSDs have no moving parts, resulting in faster read/write speeds and better durability.
B.SSDs are volatile storage media and do not require power to clear data.
C.SSDs store data using magnetic platters which have higher structural durability.
D.SSDs are significantly cheaper per gigabyte than traditional magnetic HDDs.
Explanation: SSDs utilize flash memory chipsets to store data, having no mechanical components. This lack of moving parts allows for dramatically faster read/write speeds, silent operation, and better physical durability against drops compared to mechanical magnetic HDDs.
5Which of the following describes a core function of an Operating System (OS)?
A.Managing system resources, memory allocation, and CPU scheduling.
B.Creating professional presentation slide decks and charts.
C.Scanning documents and saving them as vector design formats.
D.Designing complex database queries and web page templates.
Explanation: An Operating System (OS) is system software that acts as an interface between the computer hardware and application software. Its core functions include processor management (CPU scheduling), memory allocation, file system management, and handling input/output devices.
6Which of the following software applications is classified as system software rather than application software?
A.Device Driver
B.Word Processor
C.Web Browser
D.Spreadsheet Program
Explanation: System software controls and manages the basic operations of a computer system. A device driver is system software that allows the operating system to communicate with external hardware components. Word processors, browsers, and spreadsheets are application software designed for user tasks.
7What is the decimal equivalent of the binary number 1011?
A.11
B.9
C.13
D.7
Explanation: To convert the binary number 1011 to decimal, calculate the sum of powers of 2 for positions where the bit is 1. (1 * 2^3) + (0 * 2^2) + (1 * 2^1) + (1 * 2^0) = 8 + 0 + 2 + 1 = 11.
8How many Kilobytes (KB) are contained in exactly one Megabyte (MB) using standard binary data units (base 2)?
A.1,024 KB
B.1,000 KB
C.512 KB
D.2,048 KB
Explanation: In binary computing (base 2), computer storage is measured in powers of 2. Therefore, 1 Megabyte (MB) is equal to 2^10 Kilobytes, which is exactly 1,024 Kilobytes. While decimal standards define mega as 1,000 kilo, computers natively use binary structures.
9What is the key difference in execution between a Compiler and an Interpreter?
A.A compiler translates the entire source code into machine code before execution, whereas an interpreter translates and executes line-by-line.
B.A compiler executes code directly without translation, whereas an interpreter converts the entire file into an executable file first.
C.A compiler is used only for low-level assembly languages, whereas an interpreter is used exclusively for machine language.
D.A compiler runs code slower because it must translate each statement repeatedly during program execution.
Explanation: A compiler reads the entire source program and translates it into an independent executable machine code file (like an .exe file) before run time. An interpreter reads, translates, and executes the source code line-by-line at run time, requiring the interpreter tool to be present during execution.
10Which language type consists of binary patterns (1s and 0s) that can be executed directly by the computer processor without any translation?
A.Machine Language
B.Assembly Language
C.High-Level Language
D.Structured Query Language
Explanation: Machine language is the lowest-level programming language, consisting entirely of binary strings of 1s and 0s. Since it corresponds directly to the hardware circuitry instructions of the processor, it requires no translation to be executed.

About the CPN CLE Exam

The CPN Computer Literacy Examination (CLE) is a professional certification program designed by the Computer Professionals (Registration Council of Nigeria) for non-core IT practitioners, civil servants, students, and professionals who require structured validation of their digital literacy. The exam is structured into six modules: CLE 111 (Computer Systems & Programming), CLE 112 (Computer Software Packages), CLE 113 (Multimedia Document Production & Graphics Design), CLE 114 (Business Data Handling Processing), CLE 115 (Network & Computer Security), and CLE 116 (Web Design Technologies). Earning this certification verifies competency in standard office productivity tools, computer operations, basic data handling, network concepts, cyber security hygiene, and fundamental web technologies.
