CCNA(Cisco Certified Network Associate) is associate level of the certification from Cisco. Exam code is 200-125 with latest version CCNA 3.0. this is also called CCNA Routing and Switching because syllabus is based on routing concept and switching concept. This is the combination of Network Basic, LAN switching concepts, Routing Concepts, WAN Concepts, Network Services, Network Security and Network Management.
Networking concept based on two models, first is ISO-OSI Model and second is TCP/IP Model. There are two important protocol, which works at transport layer of OSI Model. UDP will provide fast data delivery but will be not guarantied. If will discuss about the TCP then will follow, like connection will be establish, data will be transfer and last step connection will be released. This is also called three way hand shaking. ISO gives its osi mode in 1984 and according to OSI, there are seven layers. Layer sequence will be following
1. Physical layer
2. Data link layer
3. Network layer
4. Transport layer
5. Session layer
6. Presentation layer
7. Application layer
If will talk about the TCP/IP model then there are four layers, actually it is summarise form of OSI model. Layers are following as per as TCP/IP Model
1. Link layer
2. Network access layer
3. Internet layer
4. Application layer
Every layers, there are some protocols, there are some devices, there are some address, there are some form of the data. Take example, all the cables and connector works at physical layer of osi model. Switch works at data link layer of osi model, router works at network layer of osi model. If will talk about the address then mac address, it is 48 bit address works at data link layer of osi model. If will talk about the IP Address then ipv4 is 32 bit address and ipv6 is 128 bit of address. In transport layer we have socket number, means it is the combination of ip address and port number. IP address is 32 bit address and port number is 16 bit address so total will be 48 bit address. In application layer there is port number. Port number is 16 bit address.
After this will discuss about the topology of the networking model. There are many kind of the topology, given below
1. Star topology
2. Bus topology
3. Mesh topology
4. Ring topology
5. Logical topology
6. Physical topology
7. Tree topology
8. Hybrid topology
Mesh has two kind of topology, first is partial mesh topology and second is full mesh topology. This is kind of the shape of network. Means how we are connecting our network device to the end devices.
Star topology - central device can connect with all the end devices, central device can be switch or central device can be hub. If there will be any problem in end devices then only end device will effect. If there is any problem in central device then switch or hub will effect. Now a days every small or big company also called enterprise company they have star topology.
Bus topology – now a days, no body using bus topology, only we are using in cable network, means one straight cable connected to end devices, if there will be any problem or trouble in central device then entire network will effect. If there is any problem is end device then only end device will be effected.
Mesh topology - now a days, in all the big network or enterprise network they have mesh topology. Every device connected to every one so it is called mesh topology. Data transfer rate will be very high and it has very strong redundancy of the network but definitely will be very costly compare to other network topology.
Ring topology – it is developed by IBM company. All the computers can connect with ring shape, otherwise there is one other topology, also called dual ring topology. This topology, not using by any person, previous that was using by IBM but now every company, they are using star and mesh topology.
Tree Topology – it is the combination of bus and star topology then it is called tree topology. This is the famous topology in local are network by small company and small organization.
Hybrid Topology – it is the combination of bus, mesh and star topology then it is called hybrid topology. Now a days in lan company they have mix kind of the topology so using Hybrid Topology.
