What is information technology (IT)?
Answer: Information technology is the use of computing resources, software, data, networks, and
related technologies to create, process, store, communicate, and access information.
What are the major components of IT?
Answer: Major components include hardware, software, data, networks, people, and processes.
What is an information system?
Answer: An information system is an organized combination of people, processes, data, and
technology used to collect, process, store, and distribute information.
What is the difference between data and information?
Answer: Data consists of raw facts, while information is data that has been processed and
organized so it has meaning and supports decisions.
What are the four basic operations performed by a computer?
D322 - INTRODUCTION TO IT FINAL EXAM — 2026/2027
, Answer: Input, processing, output, and storage.
What is input?
Answer: Input is the process of entering data or instructions into a computer system.
What is processing?
Answer: Processing is the manipulation of input data according to instructions to produce useful
results.
What is output?
Answer: Output is information produced by a computer after processing data.
What is storage?
Answer: Storage is the retention of data, programs, and information for later use.
What is the CPU?
Answer: The central processing unit is the component that executes program instructions and
coordinates many computer operations.
What is the role of the control unit?
Answer: The control unit directs and coordinates the activities of the CPU and other components
according to program instructions.
What is the arithmetic logic unit (ALU)?
D322 - INTRODUCTION TO IT FINAL EXAM — 2026/2027
, Answer: The ALU performs arithmetic calculations and logical comparisons.
What are registers?
Answer: Registers are very small, fast storage locations inside the CPU used to hold data,
instructions, or intermediate results.
What is the system bus?
Answer: The system bus provides pathways that allow data, addresses, and control signals to
move among computer components.
What is the system unit?
Answer: The system unit is the main computer enclosure containing major internal hardware
components.
What is main memory?
Answer: Main memory is the primary memory directly accessible by the processor for active
programs and data.
What is RAM?
Answer: Random access memory is volatile working memory used to hold programs and data
currently being processed.
What does volatile memory mean?
Answer: Volatile memory loses its contents when power is removed.
D322 - INTRODUCTION TO IT FINAL EXAM — 2026/2027
, What is DRAM?
Answer: Dynamic RAM is a common form of main memory that stores bits using memory cells
that require periodic refreshing.
What is SRAM?
Answer: Static RAM is faster and more expensive memory commonly used for CPU cache and
other high-speed applications.
What is ROM?
Answer: Read-only memory is nonvolatile memory designed to retain stored contents when
power is removed.
What is BIOS?
Answer: BIOS, or Basic Input/Output System, is firmware traditionally used to initialize hardware
and start the boot process.
What is UEFI?
Answer: UEFI is a modern firmware interface that initializes hardware and helps load an operating
system, providing capabilities beyond traditional BIOS.
What is cache memory?
Answer: Cache is high-speed memory that stores frequently used instructions and data to reduce
CPU access time.
