GUARANTEED TO PASS
⩥ Computer.
Answer: An electronic device, operating under the control of instructions
stored in its own memory, that can accept data, process the data to
produce information, and store the information for future use.
⩥ Hardware.
Answer: The device itself and its components, such as wires, cases,
switches, and electronic circuits.
⩥ Software.
Answer: Consists of the programs and apps that instruct the computer to
perform tasks. Data is processed into meaningful information.
⩥ 1) Vacuum Tubes, 2) Transistors, 3) Integrated circuits, 4)
Microprocessor, 5) Personal Computer (PC).
Answer: The order of the 5 generations of computers.
⩥ Vacuum Tubes.
,Answer: Cylindrical glass tubes that controlled the flow of electrons,
used in the first generation of computers. Due to their large size, the
amount of power they consumed, the heat they generated, and how
quickly they wore out, availability and use were limited. Examples: The
ENIAC and UNIVAC.
⩥ Transistors.
Answer: Smaller, cheaper, and more reliable replacement for vacuum
tubes in the second generation of computers. These computers contained
many components still in use today, including tape and disk storage,
memory, operating systems, and stored programs.
⩥ Integrated circuits.
Answer: Developed in the 1960s, packed the equivalent of thousands of
vacuum tubes or transistors into a silicon chip about the size of your
thumb. The third generation of computers.
⩥ Microprocessor.
Answer: Introduced by Ted Hoff and a team of engineers at Intel and
IBM, the "brains" of a computer, a chip that contains a central
processing unit. Were faster, smaller, and less expensive than integrated
circuits. The fourth generation of computers.
⩥ Personal Computer (PC).
, Answer: Computers designed for personal use, as opposed to
commercial or industrial use. Its input, processing, output, and storage
activities is performed by itself and is intended to be used by one person
at a time. Started to gain popularity in the 1970s and 1980s. The fifth
generation of computers.
⩥ Apple II.
Answer: Introduced by Steve Jobs and Steve Wozniak of Apple
Computer Corporation in 1978, a preassembled computer with color
graphics and popular spreadsheet software called VisiCalc.
⩥ Internet of Things (IoT).
Answer: An environment where processors are embedded in every
product imaginable (things), and these things communicate with one
another via the Internet or wireless networks. Often are referred to as
smart devices because of their ability to communicate, locate, and
predict. The premise is that objects can be tagged, tracked, and
monitored through a local network or across the Internet. Examples:
Alarm clocks, coffeemakers, thermostats, streetlights, navigation
systems.
⩥ Embedded computers.
Answer: A small computer that functions as one component in a larger
product, and which has a specific purpose. Has limited hardware on their
own but enhances the capabilities of everyday devices. Performs a
specific function based on the requirements of the product in which they
reside. Enables computers and devices to connect with one another over
