System and Technology Information
Technology -
any type of knowledge that can be exchange and the
information is always expressed by some of data -
in general “data
interpreted using its representation information yields information” Information
System -
group of parts or
things working together as whole -
information working
together as whole Organization Management -> analyse and decide on
operation Operation -> work done or process doing
work Information
flows or moves towards vertically Purpose
Of Information system -
operational –
improve cost efficiency on work force -
MIS – management
information system that provide information to management help in making
decision Technology -
scientific study
and use of mechanical arts and applied sciences -
application to
practical tasks in industry hence
IT is the tools to support the application of Information System IT
Hardware and Software -
hardware is tools
and equipment -
software equipments Basic Hardware
– input ( keyboard, mouse), output
(monitor, printer), processor (Pentium), input/output devices ( storage like
diskettes, floppy disk drive or
devices, hard disk drives , CDROM,
memory (Random Access Memory) ), adapter
(graphic card, network card) “brain
is to think, memorize (process) and control”
verses “computer to RAM , processor, controller” Basic
PC Component PC
Front Panel -
power light , hard
disk activity light, floppy disk drive, power button, CD-ROM drive PC
Rear Panel -
power connector
female, power connector male, CPU fan, keyboard and mouse connector, speaker, headphone and microphone
(multimedia function), D 15 pin female connector for VGA, D 25 pin female
connector printer, D 9 pin male connector for serial connection, USB
(universal serial bus) for USM devices, LAN port (8pin) and Modem port (4 pin) Printer -
output devices -
dot matrix (impact
) 9 pin and 24 pin, bubble/ink jet, laser Software
Category -
Operating System -
software to manage
computer hardware resources such as memory, storage , printer -
to manage
interaction with human -
Application System -
software to be used
to support Information System functionality Data Storage -
storage (floppy
disk, hard disk, CDROM, tape) is to store data in the form of magnetic dot (1
bit each dot) -
drive is the device
to read or write the data to or from storage (I/O) -
data storage access
type – direct access or serial access -
data can be a
program or a data for program Networking -
a group of
intelligent thing connected and communicate with a set of standard protocol
to share resources available in group -
eg restaurant
network, telephone network -
consist of
interconnection and intercommunication Interconnectivity -
cables, connector -
signal -
medium Intercommunication -
convey message
correctly -
receive massage and
translate correctly -
we need standard
protocol Standard
Network Protocol Usage
of Network -
use for certain
application Computer
Netwroking -
share resources eg
printers, modem -
communicate between
station eg e-mail, file transfer, send messages Shared
Resources -
computer which give
services is server, computer who used service is called a client or
workstation Peer
to Peer Network -
normally used for
small workgroup -
minimal security
and system control Server
Base network -
network which
server gives services to client -
centralize access
control and better security -
use in big set-up Standards -
need implementation
to ensure interconnectivity and intercommunication -
uses ISO Internet -
is the network of
network -
computer connected
to the internet able to access available information all over the world How
To Implement Information System -
require skill
worker, those who know how to use IT as a tools -
where to get it eg
higher learning institution, internal/external training program, out source Development
of Information Technology Interactive
Multimedia -
separated tools has
been used for different purposes -
allow manipulation
of multimedia content such as text, graphic, animation, movie/clip, image -
interactive mean,
man able to communicate with the multimedia program for the purpose for
visualizing if
you do not have support from the top then it is very much difficult to work
out Development
of IT Human Computer Interaction (HCI) -
command line -
graphical user
interface -
virtual reality Microminiaturization -
everybody putting
it to small , like smaller handphone, PDA Wireless
Network -
multi drop cable -
star topology
cabling – require hub and NIC -
wireless network -
require access
point and NIC -
enter into area and
you get connected
