Goals / Objectives of using ICT tools
 Maximizing citizen service
Service has to be Quick, Easy, Anytime and
Anywhere
 Minimizing operational costs
 Quick and Proactive decision making
Components of ICT
 Information – Integrated application software
taking care of operations of various
departments of organisation
 Communication – High quality network
 Techology – Hardware, Software and
language
Information
TBA, Clustered Centralise, Purely
Centralised Banking solution
TBA – Total Branch Automation
Clustered Centralised – Server and local
area network at each branch and head
office
Centralised – All the branches are
connected with head office via leased line /
vsat network
Communication
Local Area Network
 PC with NIC or LAN
card
 eCAT 5, CAT 6 Cable
 Connecting Devices
Hubs
Switches
Wireless Network
WiFi is the wireless way to handle networking. It is
also known as 802.11 networking and wireless
networking. The big advantage of WiFi is its
simplicity. You can connect computers anywhere in
your office without the need for wires. The
computers connect to the network using radio
signals, and computers can be up to 100 feet or so
apart.
The Institute of Electrical and Electronics Engineers (IEEE)
creates standards, and they number these standards in
unique ways. The 802.11 standard covers wireless
networks. The a, b and g notations identify different flavors
of the 802.11 standard:
802.11b was the first version to reach the marketplace. It is
the slowest and least expensive of the three. As mentioned
above,
802.11b transmits at 2.4 GHz and can handle up to 11 megabits
per second.
802.11a was next. It operates at 5 GHz and can handle up to 54
megabits per second.
802.11g is a mix of both worlds. It operates at 2.4Ghz (giving it the
cost advantage of 802.11b) but it has the 54 megabits per second
speed of 802.11a.
Wide Area Network
Connectivity options are Dial-up, ISDN, Leased
Line, VSAT network
When you use a normal modem on a line like
this, it can transmit data at perhaps 30 kilobits
per second (30,000 bits per second).

DS0 - 64 kilobits per second
ISDN - Two DS0 lines plus signaling (16 kilobits per
second), or 128 kilobits per second
T1 - 1.544 megabits per second (24 DS0 lines)
T3 - 43.232 megabits per second (28 T1s)
OC3 - 155 megabits per second (84 T1s)
OC12 - 622 megabits per second (4 OC3s)
OC48 - 2.5 gigabits per seconds (4 OC12s)
OC192 - 9.6 gigabits per second (4 OC48s)
Internet
Technology
Automated Teller Machine (ATM)
An ATM is simply a data terminal with two input and four
output devices. Like any other data terminal, the ATM has
to connect to, and communicate through, a host
processor. The host processor is analogous to an
Internet service provider (ISP) in that it is the gateway
through which all the various ATM networks become
available to the cardholder (the person wanting the cash).
Most host processors can support either leasedline or dial-up machines. Leased-line machines
connect directly to the host processor through a
four-wire, point-to-point, dedicated telephone
line. Dial-up ATMs connect to the host processor
through a normal phone line using a modem and
a toll-free number, or through an Internet service
provider using a local access number dialed by
modem.
Information Kiosk
The kiosks, PCs equipped with touchscreen monitors,
being used to build sophisticated information kiosks and
has far-reaching potential in Customer Access
Applications.
Touch-screen technology
makes the kiosks easy to
use—all you have to do
is touch the graphic icons
on the screen, and your
information is on the way.
The kiosk can even be
set up to provide
information, animation, or
advertisements when it is
not in use.

Requirements
Communication Network
Kiosk Hardware
Photo editing software
High end scanner
Kiosk Data Entry Application kind of
application which can help to relate specific
images to text paragraphs, or link a single
image to text in several languages
 A typical information kiosk features a rich
multimedia interface supported by animated
graphics, high quality images and high
performance operation.
 Every public or private institution with large
premises and large amounts of data in various
formats (e.g., graphics, text, audio, video,
panoramic views, etc.) can use Information
Kiosk to provide visitors, employees, students,
or tourists with comprehensive access to all the
services and information available at the site.
 The range of information that can be displayed
is limited only by the kiosk developer’s
imagination!

Mobile Internet
Wireless Application Protocol
Here's what happens when you access a Web site using a WAP
enabled device:
• You turn on the device and open the minibrowser.
• The device sends out a radio signal, searching for service.
• A connection is made with your service provider.
• You select a Web site that you wish to view.
• A request is sent to a gateway server using WAP.
• The gateway server retrieves the information via HTTP from
the Web site.
• The gateway server encodes the HTTP data as WML.
• The WML-encoded data is sent to your device.
• You see the wireless Internet version of the Web page you
selected.
• To create wireless Internet content, a Web site creates
special text-only or low-graphics versions of the site. The
data is sent in HTTP form by a Web server to a WAP
gateway. This system includes the WAP encoder, script
compiler and protocol adapters to convert the HTTP
information to WML. The gateway then sends the converted
data to the WAP client on your wireless device.
