4. Reading Definition of Terms

5. Network Services
 The term network services is used to describe a wide range of software and
connectivity tools that are managed by a central group and distributed to the
networked computers. A networked computer environment occurs when
multiple computers are connected to each other or a central server. The
computers are able to access shared files and utilities from a central location.
There are several advantages to this type of environment, ranging from
increased quality control to performance and issue management.
 Network Services include IP addressing, Domain Name System (DNS), primary
domain email service, Internet access, web content filtering, security
products such as firewalls, VPN termination and intrusion prevention systems
(IPS), and the necessary tools and staff to support these services.

6. What are the different Network
services?
 IP Addressing
 Domain Name System(DNS)
 Primary Domain Email Service
 Internet Access
 Web Content Filtering
 Security Products Such as Firewalls, Anti Virus Software
 VPN termination and intrusion prevention systems (IPS)
 Necessary tools and staff to support these services

7. IP Address/Internet Protocol Address
 IP address stands for internet protocol address; it is an identifying number
that is associated with a specific computer or computer network. When
connected to the internet, the IP address allows the computers to send and
receive information.

8. Domain Name System(DNS)

9. Domain Name System(DNS)
 is a hierarchical and distributed naming system for computers, services, and other
resources in the Internet or other Internet Protocol (IP) networks. It associates various
information with domain names assigned to each of the associated entities. Most
prominently, it translates readily memorized domain names to the numerical IP
addresses needed for locating and identifying computer services and devices with the
underlying network protocols.[1] The Domain Name System has been an essential
component of the functionality of the Internet since 1985.
 In the world of networking, computers do not represent by names like humans do, they
represent by numbers because that is how computers and other similar devices talk and
identify with each other over a network, which is by using numbers such as IP addresses.
 Humans on the other hand are accustomed to using names instead of numbers, whether is
talking directly to another person or identifying a country, place, or things, humans identify
with names instead of numbers. So in order to bridge the communication gap between
computers and humans and make the communication of a lot easier networking engineers
developed DNS.
 DNS resolves names to numbers, to be more specific it resolves domain names to IP
addresses. So if you type in a web address in your web browser, DNS will resolve the name
to a number because the only thing computers know are numbers.

10. Primary Domain Email Services
 An email domain is the part of an email address that comes after the @
symbol. For personal emails, it is most often gmail.com, outlook.com or
yahoo.com.

11. Internet access

12. Internet access
 Internet access is the process of connecting to the internet using personal
computers, laptops or mobile devices by users or enterprises. Internet access
is subject to data signalling rates and users could be connected at different
internet speeds. Internet access enables individuals or organizations to avail
internet services/web-based services.
 Internet access is often provided at home, schools, workplaces, public places,
internet cafes, libraries and other locations. The internet began to gain
popularity with dial-up internet access. In a relatively short time, internet
access technologies changed, providing faster and more reliable options.
Currently, broadband technologies such as cable internet and ADSL are the
most widely used methods for internet access. The speed, cost, reliability and
availability of internet access depends on the region, internet service
provider and type of connection.
 Internet access is the ability of individuals and organizations to connect to the
Internet using computer terminals, computers, and other devices; and to
access services such as email and the World

13. Web Content Filtering

14. Web Content Filtering
 Web content filtering is a technicque that blocks and screens access to
inappropriate or unsafe web content. Uses include a company keeping
employees from visiting known spam sites or school systems restricting
students from adult content.
 Web content filtering is the practice of blocking access to web content that
may be deemed offensive, inappropriate, or even dangerous.

15. Security Products Such as Firewalls, Anti Virus
Software

16. Security Products Such as Firewalls, Anti Virus
Software
 A firewall is a security network designed to protect computer systems and
networks from malicious attacks. Antivirus is is a software utility program
designed to protect a system from internal attacks from viruses, trojan horse,
spyware etc.
 A firewall is a security network that can be either hardware or software,
or both, and is meant to protect computer systems and networks from
harmful intrusions ..

17. VPN termination and intrusion prevention
systems (IPS)

18. VPN termination and intrusion prevention
systems (IPS)
 is the network security technology that constantly monitors network traffic to
identify threats. Under the general meaning of IPS, IPS technology is also an
intrusion detection prevention system (IDPS).
 includes anti-virus/anti-malware software, firewall, anti-spoofing software,
and network traffic monitoring. Enterprises use IPS to document threats,
uncover problems with security policies, and block external or insider security
violations.
 is typically deployed “in-line” where they sit in the direct communication
path between the source and the destination, where it can analyze in real-
time all the network traffic flow along that path and take automated
preventive action.

19. Necessary tools and staff to support these
services

20. Necessary tools and staff to support these
services
 A computer networking tool is any type that assists in the creation,
maintenance, or distribution of a wireless network. Also, computer
networking tools aid in a website’s creation, maintenance, advertising,
security, and modification.
 They are responsible for the maintenance of local area networks, especially
in situations that involve dozens or hundreds of computers within the same
network.
 Computer networking tools are used for both domestic and commercial
purposes and are available on sale or for free. Every software listed in this
article is a free computer networking tool that anyone can use for any
purpose.
 Network DOS Commands like IPCONFIG, PING, DCPROMO….

22. Application
 The class will be divided into 6 groups with a maximum of 3 members per
group. The learners will be given a chance to setup and configure a
client/server network considering the necessary Network Services, Tools and
applications.
