Introduction to Computer Flashcards
is an electronic device, operating under the
control of instructions stored in its own memory
Computer
Information Processing Cycle
- Collects Data (Input)
- Processing of Data
- Produces information (output)
can perform all of its input, processing, output, and storage activities by itself
Personal Computer
Personal computer you can carry from
place to place
Mobile
Computer
Computing device small enough to hold
in your hand
Mobile Device
is a mobile computing device designed
for single-player or multiplayer video games
Game Console
controls access to the hardware, software, and
other resources on a network
Server
Provides a centralized storage
area for programs, data, and
information
Server
is a large, expensive, powerful computer that can handle hundreds or thousands of
connected users simultaneously
mainframe
is the fastest, most powerful
computer
Supercomputer

Analytical Engine
Evolution of Computers
1st Generation (Vaccum Tubes)
2nd Generation (Transistors)
3rd Generation (Integrated Circuit)
4th Generation (Microprocessors)
5th Generation (Artificial Intelligence)
have no air
inside of them, which
protects the circuitry
Vaccum Tubes
are glass
tubes with circuits inside
Vaccum Tubes
is an electrical computer
containing thousands of vacuum
tubes that utilizes punch cards and
switches for inputting data and punch
cards for outputting and storing data
UNIVAC
Programmed UNIVAC

Award”
Grace Hopper
The first computer “bug”
Moth
Grace Hopper found a moth
stuck in a relay responsible
for a malfunction
Called it:
