Introduction of Networks

A network is a combination of computers, servers, mainframes, network devices, peripherals,
or other devices associated to one another to confess the distribution of data. An great example
of a network is the Internet, which associate millions of people all over the world. 


Types of Networks :

One style to classify the various types of computer network designs is by their scope or 
scale. For historical reasons, the networking industry assign to closely each kind of design 
as some type of area network. General kinds of area networks are :

  • LAN - Local Area Network
  • WAN - Wide Area Network
  • WLAN - Wireless Local Area Network
  • MAN - Metropolitan Area Network
  • SAN - Small Area Network
  • CAN - Campus Area Network
  • PAN - Personal Area Network

LAN and WAN are the two popular and best known kind of area networks, while the others 
have appear with technology suggestion

Note that network category vary from network topologies .

LAN : Local Area Network

A LAN associate network devices over a approximately brief distance. A networked office 
architecture , school, or home general consist of a single LAN, though sometimes one building 
will contain a few small LANs, and hardly a LAN will span a group of nearby construct . In 
TCP/IP networking, a LAN is often but not always perform as a single IP subnet.

In addition to operating in a defined space, LANs are also commonly owned, contained , and 
handled by a single person or organization. They also contribute to use certain association 
technologies, mainly Ethernet and Token Ring.

WAN: Wide Area Network

As the term signify , a WAN spans a considerable physical distance. The Internet is the largest 
WAN, spanning the Earth .

A WAN is a geographically separate combination of LANs . In IP networking, the router handle 
both a LAN address and a WAN address.
A WAN vary from a LAN in various essential styles . Most WANs  are not purchased by any one 
organization but rather access under selected or shareholding and management. WANs give to 
utilize technology like ATM, Frame Relay and X.25 for association over the expanded scope .

LAN, WAN, and Home Networking

Address commonly apply one LAN and associate to the Internet WAN via an Internet Service 
worker  using a broadband modem. The ISP offer a WAN IP address to the modem, and all of the 
computers on the home network use LAN IP addresses . All computers on the home LAN can 
associate precisely with every another but must go through a basic network gateway, commonly a 
broadband router, to ability the ISP.

Other Types of Area Networks

While LAN and WAN are by far the most leading network kinds specified , you may also generally 
see associating to these others :

  • Wireless Local Area Network - A LAN based on Wi-Fi wireless network technology
  • Metropolitan Area Network - A network connect a physical area bigger than a LAN but lesser 
    than a WAN, such as a city. A MAN is generally purchased and operated by a single entity 
    such as a government body or bigger association .
  • Campus Area Network - A network connect various LANs but lesser than a MAN, such as on a 
    university or local business ground .
  • Storage Area Network - associate servers to data storage devices through a technology like Fibre 
    medium .
  • System Area Network (also known as Cluster Area Network) - Links high-performance computers 
    with high-speed connections in a cluster configuration .

CCNA Certification – How to Become CCNA Certified

Let’s talk about how to become an CCNA Routing and Switching-certified,
 from the essential of the exam to the study components to use to prepare 
for the exam for CCNA Certification, and, finally, how long to study before
 taking the exam.

CCNA Training in Chandigarh

What Are the Prerequisites for the CCNA?

The CCNA certification is really at the basic level of the Cisco certification hierarchy, so
 there are no previous technical requirements for the CCNA exam. This means that 
you do not have to take any prior exams before you can qualify as certified by 
CCNA. However, there are age restrictions for any Cisco certification:

Under 13 years: can not be submitted for the exam, even with the consent of
 the parents.

13-17 years: can be presented for the exam with the consent of the parents.

18 years or older, without age restrictions.
Although there are no prerequisites for the end of Cisco, the CCNA exam may be
 more suitable for those with one or two years of networking experience. This should
 not confuse those who do not have practical experience and still want to take 
the test; you just need to work more and use the tools available to you, like 
GNS3 and Packet Tracer.Note: As we will see in a later section, there are 
two ways to achieve the CCNA certification.

What Study Materials Do I Need to Get Started?

As with any CCNA certification exam, there are several study materials to help
 candidates prepare for the CCNA certification exam and these materials are 
available in different formats. For example, there are study guides, videos , 
workbooks, lab guides, practice exams,

How Should I Prepare for the CCNA?

As we already talked about  of the study materials anyone can use for preparing
 the CCNA exam in the previous section.Now, we will discuss non-technical 
preparation steps for the CCNA Training exam, including preparation method 
and schedule.

Study Progress

A good way to track the progress of your study is to copy the exam topics in a
 spreadsheet and update each topic as you go through it. The level of detail you 
want to put in this tracking worksheet is up to you, but it will help you to be sure
 of what work you have already completed.

Preparation Methods

Here we have two methods you can prepare for the CCNA exam; these methods are not
 commonly absolute:

    • Self-study by using the OCG, watching videos, etc.
    • Training including boot camps and live training sessions.
    While you can prepare for the exam exclusively through self-study, you will definitely 
    add some form of self-study if you opt for the external training option i.e.  
    CCNA Training in Chandigarh.  Your choice of preparation will build on factors 
    such as budget, time, location and the possibility of success.
    External training options will cost more than self-learning, and may not be 
    available at your location. However, they generally do well in the area of time and 
    increase their chances of success in the exam. The advice here is to know yourself 
    and determine what is best for you. In addition, you can have the best of both worlds: 
    self-study and then attend a virtual training camp or watch recorded videos of a
     training camp session.

    IPv6 (Internet Protocol version 6)

    IPv6 (Internet Protocol version 6)

    IPv6 is one of the most appear technologies in networks. IPv4 addresses are almost
     disabled and, as such, a new and better solution is needed. IPv6, which is the ending 
    chapter of this  CCNA training in Chandigarh, we will look at the concepts disabled
     this protocol, we will learn why there is a need for IPv6 that will be pursue by the
     configuration of IPv6 addresses according to the requirements of the net. We'll finish
     looking at IPv6 routing using OSPF and we'll see how it differs from OSPFv2.
    CCNA Training in Chandigarh

    What is IPv6 and why is it important?

    Let’s talk about the use of IPv4 and we said that the IPv4 address space provides
     approximately 4,294,967,296 unique addresses. Of these, only 3,700 million 
    addresses are assignable because the IPv4 addressing system separates 
    addresses into classes and reservation addresses for multi casting, testing and 
    other specific uses.IPv4 addresses are almost exhausted and this is due to the
     increased use of the Internet; the number of devices with which one can use
     the Internet these days is many; Smartphones, tablets, laptops and other 
    devices can now access the Internet. Even with NAT, the rapid growth of
     the Internet is leading to the depletion of IPv4 addresses. Learn IPv6 and its 

    Advantages of IPv6

    As you can see in the following table, the use of IPv6 provides so many functions
     and possibilities that were previously not available in IPv4.
    Advantages of IPv6

    Types of IPv6 addresses

    An IPv6 address will be one of the following types. Some will be familiar, but there
     is also a new one.

    Unicast: an IPv6 unicast address is the same as an IPv4 unicast address; it is an IP 
    that is assigned to an interface on a host. It can be the source of an IP packet or the 
    destination of one. A packet sent to a unicast address goes to the only host with 
    that address.

    Global Unicast: A global unicast IPv6 address is the equivalent of a registered public
     IP address. They are IP routable by Internet, registered worldwide and must be leased
     from an ISP.

    Single Local: equivalent to a private IPv4 address; not registered with an ISP and not
     rout-able by Internet.

    Local link: each IPv6 interface is granted a local link address. The address range is 
    FE80 :: / 10, and it generally combines this prefix with the last 64 bits in EUI-64 format.
     It is more or less equivalent to the address range of the automatic private IP address 
    (APIPA) of

    Multicast: As in IPv4, a single IPv6 multicast address is assigned to multiple hosts 
    so that a packet sent to the address can be delivered to several hosts more or less
     at the same time. IPv6 multicast addresses always start with the prefix FF00 :: / 8.

    Anycast: an anycast address is a single address that is assigned to multiple hosts. 
    This is multicast, omitting that a packet for the IP address will be provided to the 
    nearest one according to the distance of ​​the routing protocol. There is no special 
    prefix for anycast addresses.

    CCNA Training in Chandigarh is the best place to learn networking and Become
     an Certified networking engineer.  

    Basic networking concepts

    What is Networking?

    A network consists of one or more systems that are connected to share resources.The networking computers shares information such as email, file, documents and resources such as printer, internet and disk storage.

    CCNA training in Chandigarh

    There are Two common type of network include:-
    1. Local Area Network (LAN)
    2. Wide Area Network (WAN)

    Local Area Network

    A Local Area Network  is a network that is restricted to limited  area. Computers connected to a network are broadly differentiate as servers and  workstations. Servers are mostly not used by human beings directly, but rather run regularly to provide services to the other computers on the network. Service contribute can include printing and software hosting, file storage and sharing messages, data storage and retrieval .

    Wide Area Network

    Wide Area Networks connect networks in larger geographic areas. Dedicated different cabling and satellite up links may be used to connect this type of global network.. A WAN is complicated network . WAN uses multiplexers, routers and bridges to connect local and metropolitan networks for over all communications networks. However, a WAN will not appear to be much different than a LAN.To learn More about networking  you can go through CCNA Training in Chandigarh.

    Requirement of Networking

    Every network requires specialized hardware and software to make them work. Following are the essential components for network:

    Client computers

    The User devices that uses to access the shared resources. Usually they run desktop version of OS such as Window 10, Window 7, and Window XP. Client computers are also known as workstations.

    Server computers

    Computers that provide shared resources. Usually they run server version of operating system such as Window Server 8 or 2003, Linux and NetWare. Server computers run many functional services to control the shared resources.

    Network interface card

    Network interface card  is an interface that empowers the computer to communicate over the network. Every computer must have a network interface card in order to connect with the network. In previous time it was a separate card and need to be installed on motherboard. All modern computers have it as the essential part of motherboard.

    Communication links

    Communication links are physical media. Every computer network needs some sort of media to transmit the data.


    When we have more than two computers in network, we cannot connect them directly. We need a mediator device that allows us to connect all computers together. Switches do this job happily. Each switch contains a certain number of ports. We can use an eight port switch to connect eight computers.


    Router is an intermediate device that speaks all language of network. It makes communication between two different networks.

    Benefits of Networking

    Networking is all about sharing. Networking allows us to share three main things: information, resources and applications sharing .For More information go with CCNA Training in Chandigarh.

    Information sharing

    Networking makes it easy to share the information across the network. We can send or receive data files from other computers. We can communicate with each other in network via messaging application for example email service, chat service etc. We can store data in a centralized server for easy management.

    Resources Sharing

    Certain computer resources can be shared in the network such as hard disk, printer, scanner, modem etc. This allows us to track down the uses of resources. For example a network administrator can setup a printer server and share it in network. Then user can use printer server for printing. Now administrator needs only to monitor the print server instead of individual workstations.

    Application Sharing

    Application sharing is the most common in companies. Companies may have business application that needs to be update by several users. Sharing make it possible. It allows several users to work together on a single application.

    I hope you understand the Basics of networking. To learn More about networking you can go through CCNA Training in Chandigarh

    Learn More Topics from Packet tracer Itself

    Wednesday, March 15, 2017

    Hello friends,

    Here in this article today, i am going to tell you some very intersting facts about Cisco Packet tracer i have learned in CCNA Training in Chandigarh. You must be having curiosity to learn as much as you can in CCNA. Some of the topics which are not in the CCNA Syllabus but you want to learn them can be learn from packet tracer itself. Are you excited to know how we can do it.

    After installing Cisco Packet Tracer some of the folders by get installed in the C:/ Drive of the computer system. When you will go to the saved folder you can get more informative Cisco Packet Tracer files of the topology in which so many other technical practicals are performed. Either you are using Linux or Windows. In both operating systems you can find the same folder in which you can find the CCNA Practicals. These practicals are already performed and you also can get the commands which has been run in the routers and in the switches. You can retrieve all the configuration from the routers by which you can learn that how this practicle has been performed.

    This is the folder in which you can see all the practical.

    In windows you have to follow the path

    C:\Program Files (x86)\Cisco Packet Tracer 6.0.1\saves

    This is the path where you can find the topologies which is already configured and must be new to you. From them you can learn many more new thing in CCNA Training in Chandigarh.

    Here in this image you can see the the folder in which you will find the Topologies.

    When you will enter in this folder you will see some more folders in this folder. Those all folders are listed below.

    1. 6.2
    2. Linksys
    3. PC
    4. Router
    5. Security
    6. Server
    7. TCP_IP
    8. TV
    9. Voice_IPPhone
    10. Wireless

    You can see these folders in the image given below.

    These are the folders you can find in Saves folder in cisco Packet Tracer. Now when you click in these folders you will find the PKT file in it. These files will run in packet tracer and you can check the configurations of the practicals which has been performed in them.  

    Along with all that you also can take CCNA Training in Chandigarh to become network Professional.
