Verified Answers 100% Correct (A+)
• Why is understanding IT important for users? -✓✓It allows users to provide better
input, recommend IT applications, spot new tech, understand IT's impact on
performance, and leverage IT knowledge as an advantage.
• What is the role of a Chief Information Officer (CIO)? -✓✓The CIO is the executive in
charge of the IS function.
• What is hardware in the context of Computer-Based Information Systems? -
✓✓Hardware is the physical equipment used for input, processing, output, and storage.
• What is the CPU? -✓✓The CPU (Central Processing Unit) is the 'brain' of the
computer that manipulates data and controls tasks performed by other components.
• What is primary storage? -✓✓Primary storage temporarily stores data and program
instructions during processing.
• What is secondary storage? -✓✓Secondary storage stores data/programs for future
use (long-term, non-temporary).
• How is data measured? -✓✓Data is measured using bits and bytes (and larger units).
• What are registers in a computer? -✓✓Registers are part of the CPU with the least
capacity, storing tiny amounts of instructions/data immediately before/after processing.
• What is cache memory? -✓✓Cache memory is high-speed memory that stores
frequently used data blocks for faster access than RAM.
• What is RAM? -✓✓RAM (Random Access Memory) holds software programs and
small amounts of data for processing.
• What is ROM? -✓✓ROM (Read-Only Memory) is a chip with critical safeguarded
instructions that is nonvolatile.
• What is the key relationship between storage types and CPU proximity? -✓✓The
closer the storage to the CPU, the faster the access, usually with smaller capacity
(Registers → Cache → RAM).
, • What is the difference between SSDs and traditional hard drives (HDD)? -✓✓SSDs
store data in memory chips with no moving parts, making them faster and more reliable
than HDDs, which are typically slower and have moving parts.
• What is flash memory? -✓✓Flash memory is nonvolatile electronic storage with no
moving parts, using less battery power than hard drives.
• What is the capacity of a CD compared to a DVD? -✓✓A CD can hold about 700MB
(80 minutes audio), while a DVD can store more due to denser physical spacing and
can have two layers per side.
• What is the difference between primary and secondary storage? -✓✓Primary storage
is temporary and fast (used during processing), while secondary storage is long-term
and persistent (used for saving files/programs).
• What is the role of software in computing? -✓✓Software provides instructions to a
machine, making hardware useful.
• What are the categories of software? -✓✓System Software includes OS, programming
languages, and system utilities; Application Software includes programs used by end
users.
• What is an Operating System (OS)? -✓✓An OS is essential system software that
every general-purpose computer has.
• What is a single-user OS? -✓✓A single-user OS is designed primarily for one user
(e.g., Windows, Mac OS, Android).
• What is a multiuser OS? -✓✓A multiuser OS supports many concurrent users (e.g.,
Linux, Unix, Windows Server editions).
• What are the functions of an Operating System? -✓✓OS provides a user interface,
manages system memory, processing tasks, networking capability, controls access to
resources, and manages files.
• What is BIOS? -✓✓BIOS (Binary I/O System) is referenced as part of system-level
startup and device interaction.
• What is proprietary software? -✓✓Proprietary software is owned by a company, and
copying it without permission is considered piracy.
• What is open-source software? -✓✓Open-source software has source code available
under a license that allows users to study, change, improve, and sometimes distribute it.
