Description
GENERAL APPLICATION OF ICT
ICT Application in Everyday Life
ICT is an acronym for Information Communication Technology. It covers all forms of
computer and communication equipment and software used to create, design, store,
transmit, interpret and manipulate information in its various formats. Examples of ICT
TOOLS are laptops, tablets, network technologies, mobile phones and so on as well
as the various services and applications associated with them such as video
conferencing, telecomputing and so on.
ICT APPLICATIONS
E-LEARNING: ICT can contribute to achieving universal education worldwide, through
the delivery of education and training of teachers and offering improved conditions for
long life learning, encompassing people that are outside the formal education process
and improving professional skills.
Benefits
• Develop domestic policies to ensure that ICTs are fully integrated in education
and training at all levels.
• Promote e-literacy skills for all, for example by taking advantage of existing
facilities such as libraries and so on.
• Develop distance learning, training and other forms of education as part of
capacity building programmes.
• Help to train users to develop self-learning and self-development capacities.
E-BUSINESS
• Better Customer Service: E-business has improved customer service. Many a
time on visiting a website, the customer is greeted by a pop-up chat window.
Readily available customer service may help in encouraging the customer to
know about the product or services.
• Reduces Transaction Cost: Websites are sufficiently loaded with directions to
facilitate stress free transactions. The mode of payments is predetermined,
promising security to the customer. All you are left with, as the proprietor of your
online business, is to download the requirement order and ship it.
• Flexible Business Hours: E-business breaks down the time barriers that locationbased businesses encounter, because the internet is available 24hrs a day.

05 IP Routing Basics
Trending!
There are typically multiple IP subnets on a typical data communication network.
Layer 3 devices are required to exchange data between these IP subnets. These
devices have the routing capability and can forward data across subnets.
Routing is the basic element of data communication networks. It is the process of
selecting paths on a network along which packets are sent from a source to a
destination.
This note introduces the basic concepts of routing.

06 OSPF Basics
Trending!
Static routes are manually configured. If a network topology changes, static routes
have to be manually adjusted, which restricts the large-scale application of static
routes on the live network.
Dynamic routing protocols are widely used on live networks because of their high
flexibility, high reliability, and easy scalability. The Open Shortest Path First (OSPF)
protocol is a widely used dynamic routing protocol.
This course describes basic concepts,working mechanism, and basic configurations of OSPF.

07 Ethernet Switching Basics
Trending!
Data transmission on networks must comply with certain standards. Ethernet
protocols define how data frames are transmitted over an Ethernet network.
Understanding Ethernet protocols is the basis for fully understanding
communication at the data link layer. An Ethernet switch is the main device for
implementing data link layer communication. It is essential to understand how an
Ethernet switch works.
This note describes the concepts related to Ethernet protocols, MAC address
types, and working process and mechanism of Layer 2 switches.

08 VLAN Principles and Configuration
Trending!
Ethernet technology implements data communication over shared media based
on carrier sense multiple access with collision detection (CSMA/CD). If there are a
large number of PCs on the Ethernet, security risks and broadcast storms may
occur, deteriorating network performance and even causing network breakdowns.
The virtual local area network (VLAN) technology is therefore introduced to solve
the preceding problem.
This note describes basic VLAN principles, working principles of different Layer 2
interfaces, VLAN applications, data forwarding principles, and basic VLAN
configuration methods.

09 STP Principles and Configuration
Trending!
On an Ethernet switching network, redundant links are used to implement link backup and enhance network reliability. However, the use of redundant links may produce loops, leading to broadcast storms and an unstable MAC address table. As a result, communication on the network may deteriorate or even be interrupted. To prevent loops, IEEE introduced the Spanning Tree Protocol (STP).
Devices running STP exchange STP Bridge Protocol Data Units (BPDUs) to discover loops on the network and block appropriate ports. This enables a ring topology to be trimmed into a loop-free tree topology, preventing infinite looping of packets and ensuring packet processing capabilities of devices.
IEEE introduced the Rapid Spanning Tree Protocol (RSTP) to improve the network
convergence speed.

10 Inter-VLAN Communication
Trending!
By default, a Layer 2 switching network is a broadcast domain, which brings many
problems. Virtual local area network (VLAN) technology isolates such broadcast
domains, preventing users in different VLANs from communicating with each
other. However, such users sometimes need to communicate.
This course describes how to implement inter-VLAN communication.

11. Eth-Trunk, iStack, and CSS
Trending!
As services develop and the campus network scale expands, users have
increasingly demanding requirements on network bandwidth and reliability.
Traditional solutions improve network bandwidth by upgrading devices and
implement high reliability by deploying redundant links and using the Spanning
Tree Protocol (STP), leading to low flexibility, time-consuming troubleshooting, and
complex configuration.
This chapter describes how to use Eth-Trunk, intelligent stack (iStack), and cluster
switch system (CSS) technologies to improve network bandwidth and reliability.

12 ACL Principles and Configuration
Trending!
Rapid network development brings challenges to network security and quality of service(QoS). Access control lists (ACLs) are closely related to network security and QoS. By accurately identifying packet flows on a network and working with other technologies, ACLs can control network access behaviors, prevent network attacks, and improve network bandwidth utilization, thereby ensuring network environment security and QoS reliability. This course describes the basic principles and functions of ACLs, types and characteristics of ACLs, basic composition of ACLs, ACL rule ID matching order, usage of wildcards, and ACL configurations.

13. AAA Principles and Configuration
Trending!
User management is one of the most basic security management requirements for
any network. Authentication, authorization, and accounting (AAA) is a management framework that provides a security mechanism for authorizing some users to access specified resources and recording the operations of these users. AAA is widely used because of its good scalability and easy implementation of centralized management of user information. AAA can be implemented through multiple protocols. In actual applications, the Remote Authentication Dial-In User Service (RADIUS) protocol is the most commonly used to implement AAA.
This course describes the basic concepts, implementation, basic configurations, and
typical application scenarios of AAA.

14 Network Address Translation
Trending!
With the development of the Internet and the increase of network applications,
limited public IPv4 addresses have become the bottleneck of network
development. To solve this problem, Network Address Translation (NAT) was
introduced.
NAT enables hosts on an internal network to access an external network. It not
only helps alleviate IPv4 address shortage but also improves the security of the
internal network as NAT prevents devices on the external network from directly
communicating with hosts on the internal network that uses private addresses.
This course describes the motivation behind NAT, and implementations and
application scenarios of different types of NAT.
