First users were the engineers who built and programmed computers, then employees
who had received specialized training were users, and now today, anyone and
everyone can be a user. - >>>>>>>ANSWER Evolution of Users
Sends files over the network at the request of clients. Responds over LAN, within one
location/site. Support both application software and data files. - >>>>>>>ANSWER FILE
SERVER
Turns a user-friendly domain name, like Google.com, into an Internet Protocol (IP)
address like ((( 70.42.251.42 ))) that computers use to identify each other on the
network. - >>>>>>>ANSWER Domain Name Server (DNS)
Uses TWO KEYS a public and private key for performing encryption and decryption -
>>>>>>>ANSWER Public Key Encryption
PROVING you are who you say you are which can be done by: what you know, what
you have! - >>>>>>>ANSWER Authentication
TIER WHERE THE USER interface for the system is developed; SHIELDS THE USER
from the underlying logic of the systems as well as the underlying data structures -
>>>>>>>ANSWER Presentation Tier
SYSTEMS DEPLOYMENT Steps 1. System Conversion 2. Final Documentation 3. End
User Training - >>>>>>>ANSWER System Deployment
CONNECTS MULTIPLES networks together; can be used to directly connect computers
to a network; will relay messages to computers with APPROPRIATE IP ADDRESS -
>>>>>>>ANSWER ROUTER
Requires that data is KEPT secure so that they are not accidentally provided or
obtained by unauthorized users - >>>>>>>ANSWER Confidentiality
Protecting EVERY LAYER that SURROUNDS ((( DATA ))) - >>>>>>>ANSWER
Defense in Depth
Can take on DIFFERENT FORMS depending on the complexity of the application; in
certain instances, it is AN ACTUAL OBJECT that is an ACTUAL IMPLEMENTATION of
the application - >>>>>>>ANSWER THE MODEL
Creates a subset of the data by reducing the data from multiple dimensions to one
dimension - >>>>>>>ANSWER Slicing Data
The technology used in creating, maintaining, and making information accessible. -
>>>>>>>ANSWER Information Technology
In charge of all aspects of the COMPUTER NETWORKS - >>>>>>>ANSWER Network
Administrator
Focuses on the design, development, and support of DATABASE MANAGEMENT
systems (DBMSs). - >>>>>>>ANSWER Database Administrator
Installs, configures, maintains, secures, and troubleshoots web severs -
>>>>>>>ANSWER Web Administrator
Processed data. - >>>>>>>ANSWER Information
, INFORMATION THAT HAS BEEN PUT TO USE information placed into a context.
Refined information such that the user of the knowledge is able to call forth only
relevant portions of information when needed. - >>>>>>>ANSWER Knowledge in DIKW
Provides a social setting to knowledge; AN UNDERSTANDING OF THE ((( WHY )))
Can only come by having BOTH KNOWLEDGE and EXPERIENCE -
>>>>>>>ANSWER WISDOM
The INPUT Processing, OUTPUT, STORAGE Cycle - >>>>>>>ANSWER I.P.O.S.
Raw data is organized or structured for usefulness. - >>>>>>>ANSWER PROCESSED
DATA
Information is output so user can see results. - >>>>>>>ANSWER OUTPUT DATA
Processed information is stored for permanent record. - >>>>>>>ANSWER STORAGE
A collection of components that work together to meet the needs of the user; typically :
CATEGORIZED AS EITHER HARDWARE, SOFTWARE, NETWORKS AND USERS -
>>>>>>>ANSWER COMPUTER SYSTEM
Physical components of a computer system which include the system unit and its
components and peripheral devices; TANGIBLE ASPECTS OF THE COMPUTER -
>>>>>>>ANSWER HARDWARE
A collection of computers and resources CONNECTED by various media so that they
can COMMUNICATE WITH EACH OTHER. - >>>>>>>ANSWER NETWORK
Systems Software and Applications Software - >>>>>>>ANSWER SOFTWARE
CATEGORIES
RULES provided by WHICH NETWORKS communicate with each other -
>>>>>>>ANSWER IP PROTOCOL
STORES the programs BEING EXECUTED and the data they are using. -
>>>>>>>ANSWER COMPUTER MEMORY
Controls THE SPEED at which instructions are processed. - >>>>>>>ANSWER
SYSTEM CLOCK
Stands for Random Access Memory. It temporarily stores 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). - >>>>>>>ANSWER RAM
Transistor components, magnetic core memory, smaller size, easier to program, disk
drives and drums, called mainframe computers - >>>>>>>ANSWER 2nd Generation of
Computers
Silicon chips (known as ICs - integrated circuits), reduced cost, called mini computers,
networks introduced via dumb terminals - >>>>>>>ANSWER 3rd Generation of
Computers
Written for a specific machine by the engineers who built and ran the computers; no
need for OS since only one program could run at a time - >>>>>>>ANSWER Low-level
Language
Easier than machine but still required detailed, precise LOW LEVEL instructions -
>>>>>>>ANSWER Assembly Language
Function is to TRANSLATE ONE LANGUAGE TO ANOTHER; take source code and
convert it to another form; source code by itself cannot be read by a computer -
>>>>>>>ANSWER Language Translator Programs
