A+)
Algorithm - ANSWER A precise sequence of instructions for processes that can be
implemented in a programming language and executed by a computer.
Control Structure - ANSWER one or more programming language statements that
control the flow of a computer program. Examples: If/Else structure or a loop structure.
Computer - ANSWER a machine that processes information under the control of a
program.
Program - ANSWER sequence of instructions that control the computer. To run, it must
be loaded into the computer's memory where the CPU executes it one instruction at a
time.
Hardware - ANSWER the computer's electronic and mechanical components.
Software - ANSWER the programs that control computers
General purpose computer - ANSWER a computer that can run many different
programs (e.g. a smartphone).
Special purpose computer - ANSWER a computer that has a fixed program ( e.g. a
calculator, a watch, a car's brakes)
Memory - ANSWER physical device used to store information for use in a computer or
other digital electronic device( e.g. disk drive, flash drive)
RAM - ANSWER Random Access Memory- also called main memory stores the
computer's programs and data temporarily while power is on.
CPU - ANSWER Central Processing Unit is the hardware that carries out the
instructions of a computer program. It is made up of 3 main parts: the control unit (CU),
the arithmetic and register. The CU processes the program's instructions, the ALU
(arithmetic logic unit) performs the arithmetic and logic operations and the register
stores intermediate data during program execution.
Input devices - ANSWER bring data and programs into the computer (e.g. mouse,
keyboard)
Output devices - ANSWER transmit data to other computers to users (e.g. printer,
monitor, speaker)
, Motherboard - ANSWER houses the computer's main electronic components
Chips - ANSWER the computer's electrical components are composed of these very
tiny integrated circuits.
Selection - ANSWER In a selection structure, a question is asked, and depending on
the answer, the program takes one of two courses of action, after which the program
moves on to the next event.
Sequence - ANSWER The sequence control structure is simple a sequence of one or
more statements in a computer program
Event-Driven Programming - ANSWER a programming approach whereby the
program's behavior is controlled by writing code that responds to various events that
occur, such as Button clicks.
Binary Number - ANSWER a number written in the binary system, a system that uses
only two digits, 0s and 1s.
blacklist - ANSWER in internet terminology, a generic term for a list of email addresses
or IP addresses that are origination with known spammers
character - ANSWER any symbol that requires one byte of storage
cyberspace - ANSWER a metaphor for describing the non-physical terrain created by
computer systems
data - ANSWER distinct information that is formatted in a special way. Data exists in a
variety of forms, like text on paper or bytes stored in electronic memory.
data center - ANSWER physical or virtual infrastructures used by enterprises to house
computer, server and networking systems and components for the company's IT
(information technology) needs
data network - ANSWER a telecommunications network which allows computers to
exchange data
disk drive - ANSWER a randomly addressable and rewritable storage device
intellectual property - ANSWER refers to any property that is created using original
thought. Traditional intellectual property include patents, copyrights, and trademarks.
Moore's Law - ANSWER The number of transistors per square inch on integrated
circuits has doubled every year since the integrated circuit was invented.
network - ANSWER a group of two or more computer systems linked together
