First users were the engineers who built and Evolution of Users
programmed computers, then employees who had
received specialized training were users, and now today,
anyone and everyone can be a user.

The INPUT Processing, OUTPUT, STORAGE Cycle I.P.O.S.
Raw data is organized or structured for usefulness. PROCESSED DATA
Information is output so user can see results. OUTPUT DATA
Processed information is stored for permanent record. STORAGE
A collection of components that work together to meet COMPUTER SYSTEM
the needs of the user; typically : CATEGORIZED AS
EITHER HARDWARE, SOFTWARE, NETWORKS AND
USERS
Physical components of a computer system which HARDWARE
include the system unit and its components and
peripheral devices; TANGIBLE ASPECTS OF THE
COMPUTER
A collection of computers and resources CONNECTED NETWORK
by various media so that they can COMMUNICATE
WITH EACH OTHER.
Systems Software and Applications Software SOFTWARE CATEGORIES

with each other
STORES the programs BEING EXECUTED and the data COMPUTER MEMORY
they are using.
Controls THE SPEED at which instructions are SYSTEM CLOCK
processed.

Stands for Random Access Memory. It temporarily stores RAM
data before it is processed and sent to your screen or
printer. IT IS VOLATILE (means data or information
stored disappears when the computer is turned off or
loses power).
Transistor components, magnetic core memory, smaller 2nd Generation of Computers
size, easier to program, disk drives and drums, called
mainframe computers
Silicon chips (known as ICs - integrated circuits), 3rd Generation of Computers
reduced cost, called mini computers, networks
introduced via dumb terminals
Written for a specific machine by the engineers who built Low-level Language
and ran the computers; no need for OS since only one
program could run at a time
Easier than machine but still required detailed, precise Assembly Language
LOW LEVEL instructions
Function is to TRANSLATE ONE LANGUAGE TO Language Translator Programs
ANOTHER; take source code and convert it to another
form; source code by itself cannot be read by a computer
Programmer is limited to high level control constructs Structured Programming
such as while loops, for loops, and if/else statements and
not allowed to use primitive GOTO statements
A type of programming language for which most of its Interpreted Language (Code)
implementations EXECUTES INSTRUCTIONS
DIRECTLY AND FREELY, without previously compiling a
program into machine-language instructions.

computers.
Like a hub, but this will only send data that is INTENDED Network Switch
FOR SPECIFIC COMPUTER
Can be connected to hub, switch, or router; many routers Wireless Access Point
now also act as a wireless access point; sends out a
wireless signal so computers on the network can connect
without a cable
Contains one or more servers; client is a computer that Client-server Network
will request information from another computer; server is
a computer that takes requests and responds with the
requested information; the software used facilitates
communication with remote servers
Stores data files (web pages) and programs (scripts). Web Server
Responds from anywhere on the Internet.
