Essentials Exam Updated Actual Question and
Answer (2026/2027) | Detailed Rationales
• Computer Hardware . CORRECT ANSWER: the physical equipment used for
input, processing, and output activities in an information system (desktop,
handheld devices, mainframe, motherboard, CPU chip, RAM memory)
• software . CORRECT ANSWER: the programs and other operating information
used by a computer (operating system, application software, database software,
presentation software)
• network . CORRECT ANSWER: communication links that allow the computer
systems to communicate with each other no matter the distance/location (routers,
switches)
• data . CORRECT ANSWER: Facts and statistics collected together for reference
or analysis (can be used for trend analysis, projections of sales revenue, other
applications of viewing and massaging the data)
• end user . CORRECT ANSWER: The person or group who will use the
hardware, software, networks, and databases in their performance of their daily
work
• processes . CORRECT ANSWER: the applications that a business uses in its
daily operations
• mainframe computer . CORRECT ANSWER: massive, room-sized computers
that process and store enormous amount of bulk data and information
,• minicomputers . CORRECT ANSWER: less powerful and smaller in physical
size than mainframe computers
• microcomputers . CORRECT ANSWER: smaller than mainframes and midrange
computers and are so common that they are most commonly referred to as
computers and sometimes referred as boxes
• system software . CORRECT ANSWER: software that runs in the background
and requires very little or no user intervention
• operating software (platform) . CORRECT ANSWER: a collection of computer
programs that work together to manage hardware and software to ensure that they
are working properly
• file management . CORRECT ANSWER: storing and organizing files in the
memory of a computer
• Graphical User Interface (GUI) . CORRECT ANSWER: the visual system of a
computer screen designs that allow a user to interact with an electronic device
• multitasking . CORRECT ANSWER: when a computer runs more than one
process at a time
• process . CORRECT ANSWER: any task a computer performs
• memory management . CORRECT ANSWER: operating systems coordinate a
computer's memory, which includes cache, random access memory (RAM),
registers, and virtual memory
, • cache . CORRECT ANSWER: a hardware or software component that stores
data so that future requests for that data can be served faster
• RAM . CORRECT ANSWER: a type of memory that allows data to be accessed
in any other without physical movement of the silicone media (primary storage)
• Disk Management . CORRECT ANSWER: An OS is responsible for reading and
writing data and information to a disk, typically a hard drive, solid-state drive
(SSD), or main memory
• solid-state drive . CORRECT ANSWER: a storage device that typically uses
flash memory to store data, instructions, and information
• disk storage . CORRECT ANSWER: Non-volatile, secondary storage that is
recorded to a physical device like a hard drive or optical disk with a read/write
apparatus.
• optical disk . CORRECT ANSWER: a computer disk that uses optical storage
techniques and technology to read and write data
• file allocation table (FAT) . CORRECT ANSWER: a table of contents that
directs the read/write arm of the hard drive to the location where data exists and
accesses the data upon the user's request
• application software . CORRECT ANSWER: computer software created to
allow the user to perform a specific job or task
(will not work without system software)
