INTRO TO COMPUTER SCIENCE
CERTIFICATION EVALUATION 2026 EXAM
Q&A STUDY SHEET
◉Shareware. Answer: software that you can use on a trial basis
before paying for it. Unlike freeware, shareware often has limited
functionality or may only be used for a limited time before requiring
payment and registration. Once you pay for a shareware program,
the program is fully functional and the time limit is removed.
◉Memory. Answer: The ordered sequence of storage cells that can
be accessed by address. Instructions and variables of an executing
program are temporarily held here.
-Computer memory is set up to represent and store information in
electronic form
-The information stored in memory can represent any type of data,
such as numbers, text, images, or sound, or the instructions of a
program
,◉CPU. Answer: A major hardware component that consists of the
arithmetic/logic unit and the control unit. Also sometimes called a
processor.
-Central Processing Unit; the brain of the computer.
-Executes an algorithm by fetching its binary instructions from
memory, decoding them, and executing them
-Main chip in a computer
-Controls the activities of other chips as well as the devices
connected to the computer such as the monitor and the printer
-Large number of terminals
◉Input. Answer:
◉Output. Answer:
◉Port. Answer: A channel through which several clients can
exchange data with the same server or with different servers
◉Chapter One-Part Two: Vocabulary Words. Answer:
◉Read-Only Memory (ROM). Answer: memory containing
hardwired instructions that the computer uses when it boots up,
before the system software loads
, ◉Random Access Memory (RAM). Answer: A data-access method
that runs in constant time
-The main memory. Also called the primary memory.
-Used for temporary storage of data during manipulations.
-Content vanishes when the computer is turned off
◉Flash Memory (?). Answer: type of electrically erasable
programmable read-only memory. a section of memory cells can be
erased in a single action or in a "flash."
◉Types of Storage Media. Answer: -Magnetic Storage Media
-Semiconductor Storage Media
-Optical Storage Media
◉Optical Storage Media. Answer: Devices such as CDs and DVDs that
store data permanently and from which the data are accessed by
using laser technology
◉Magnetic Storage Media. Answer: Any media that allow data to be
stored as patterns in a magnetic field
-Tapes and Hard Disks
◉Semiconductor. Answer: Devices, such as flash sticks, that use solid
state circuitry to store data permanently
