This document summarizes a networking presentation by CAS Group. It discusses virtual networking using virtual machines, wired networking using switches and routers, and wireless networking using WiFi access points. Key topics covered include the definition of virtual machines and their advantages, how to set up wired and wireless local area networks, and demonstrations of file sharing, remote desktop connections, and shutting down computers on the network. The presentation aims to teach networking concepts and skills to IT students.

4. WHAT IS CAS?
 CAS stands for “CSIT ASCOL Society”
 It indicates the unity among every IT team in ASCOL
college in IT field
 Our motto is to teach and learn together from base to
the top regarding any new technology and to make
every IT student skilled as they should be being IT
student and to unleash the technological potential of
the student.
 Our slogan we believe in doing practically rather then
wasting time in discussing
 CAS is a social group for all the beginner,
intermediate and expert people.

5. TODAYS TOPICS HIGHLIGHTS
 Virtual networking
 Wired networking
 Wireless networking
 And other small topics

6. WHAT IS VIRTUAL MACHINE?
 Here Virtual machine means a software
which provide us a platform to create as
many virtual computers depending upon
system configuration of our computer.
 Mostly used virtual machine
 1.Oracle VM Virtual box {freeware}
 2.VM Ware {pay money}

7. ADVANTAGES OF VIRTUAL MACHINE
 Create a independent virtual computer
 Different OS can be installed
 we can manage RAM, HDD, Processor, ODD, pendrive
etc
 If virtual computer is damaged then we can create new
virtual computer, it does not harm any of our system files
and our document.
 By using virtual machine many people have been able to
be familiar with different type of OS. Eg linux, windows,
MAC, Sun Solaris etc.
 New software can be tried before use in real machine.
 Every hacking, Networking, can be learned by creating
virtual computers.

8. WHY SHOULD WE USE VIRTUAL MACHINE?
 We should use virtual machine in order to
practice and to learn.
 So that we don’t make any mistake on our
real machine.
 To try new software and new ideas.

9. POWER ISO AND ISO IMAGE
Power iso is a software which help us to create
and extract zip type of file which is also called
image. it help us to create duplicates of the
films in cd, or software from a cd or to zip any
file.
 it can create different extension images such
as
 1. .iso
 2. .daa
 3 .bin

10. ISO IMAGE
 We can create iso image for using virtual
machine because in virtual machine we can
open iso image as an dvd-rom.

11. WHAT IS NETWORKING?
 Networking is connection of two or more
computers with wire or wireless connection
to share it’s available resources.
 Such as
 Harddisk, cd-rom, printer, software and files
etc
 Important note- we don’t need internet to do
networking.

12. ADVANTAGES OF NETWORKING
 Helps us to share available resources such as
printer, scanner, cd-rom, harddisk
 Help us in communication such as calling,
messaging, etc
 Help us to solve problem staying in same place.
E.g remote desktop connection
 Makes our daily work easier.
 RIS(Remote Installation Service)
 Internet sharing

13. DISADVANTAGES OF NETWORKING
 If one computer is infected with viruses then
whole computer will be infected by viruses.
 If switch is not working then whole network
system does not work.
 etc

14. TYPES OF NETWORKING
 LAN
 MAN
 WAN
 PAIR TO PAIR NETWORKING
 SERVER CLIENT NETWORKING

15. LAN(LOCAL AREA NETWORKING)
 The networking done in small area.
 i.e within room or from one room to another
or within a building
 E.g school, colleges, offices, institute
 And today we will do LAN networking with
wire and wireless i.e wifi.

16. SIMPLE LAN NETWORK WITH SWITCH ONLY

17. COMPLEX LAN WITH ROUTER AND WIFI

18. MAN(METROPOLITAN AREA NETWORK)
 . A network connecting computers over a
large geographical area, such as a city or
school district.

19. MAN

20. WAN(WIDE AREA NETWORKING)
 The networking in wide area.
 E.g internet

21. WAN

22. NETWORKING CAN BE DONE BY DIFFERENT
WAYS
 1. WITH COMPUTER NAME
 2.WITH IP ADDRESS
 TYPES
 CLASS A
 CLASS B
 CLASS C

23. TODAY WE WILL DO LAN NETWORKING WITH
COMPUTER NAMES
 Because we are going to do networking in
small area i.e in a hall. But before that we will
practice networking in virtual machine.
 After that we will do networking with wires
and wireless devices.

24. NETWORKING WITH COMPUTER NAMES
 It is the easiest way of networking because
here we don’t have to know what is static
and dynamic IP address is.
 But in reality, while doing networking,
computer name uses dynamic ip address.
 Dynamic ip address means ip address
changes frequently.
 It is used widely

25. NETWORING WITH COMPUTER NAMES
 RULES
 Some rules must be followed in order to
make a networking of the computers
 1.Computer name must be different but
workgroup must be same.
 2.Firewall must be off
 3.Guest must be enabled
 4. Guest must be given access in network

26. 1.COMPUTER NAME MUST BE DIFFERENT AND
WORKGROUP MUST BE SAME
 Right click on my computer.
 Properties  Computer name  Change
 Give the computer name and workgroup.
 Restart your computer.

27. 2.FIREWALL MUST BE OFF
 Start  control panel  firewall  off
 Or
 Win+r  firewall.cpl  off

28. 3.GUEST MUST BE ENABLED
 Right click on my computer
 Manage  local users and groups 
users  double click on guest  remove
tick from account is disabled.
 Or
 Win+r  lusrmgr.msc  users  double
click on guest  remove tick from account
is disabled.

29. 4.GUEST MUST BE GIVEN ACCESS IN NETWORK
 Start  control panel  administrative tools
 local security policy  local policy 
user right assignment  double click on
deny access to this computer from network
 select guest  remove  ok
 Or
 Win+r  secpol.msc  local policy  user
right assignment  double click on deny
access to this computer from network 
select guest  remove  ok

30. THE THINGS WE CAN DO AFTER WE ARE IN
NETWORK
