A subnet is a group of IP address. It can reach any address without using any routing device if they belong to the same subnet. So far we have seen different protocols, segmentation, various communication layers, etc. Now we are going to see how the packet is delivered across the network. The process of delivering data from one host to another depends on whether or not the sending and receiving hosts are in the same domain. If the receiving and sending devices are connected to the same broadcast domain, data can be exchanged using a switch and MAC addresses.
But if the sending and receiving devices are connected to a different broadcast domain, then the use of IP addresses and the router is required. Suppose host A wants to send a packet to host B. Since at layer 2 packets are sent with MAC address as the source and destination addresses.
If a packet is destined for a system on the same local network, which means if the destination node are on the same network segment of the sending node. The sending node addresses the packet in the following way. In the case where two nodes residing on different network segments, packet routing will take place in the following ways. It is used to connect devices to a LAN. Technically it is referred as WLAN is a wireless network communication over short distances using radio or infrared signals.
Any components that connect to a WLAN is considered as a station and falls into one of two categories. Radio frequencies range from the frequencies used by cell phones to the AM radio band. Radio frequencies are radiated into the air by antennas that create radio waves. To establish WLAN standards and certifications, several organizations have stepped forward. Organization has set regulatory agencies to control the use of RF bands.
Approval is taken from all the regulatory bodies of WLAN services before any new transmissions, modulations and frequencies are used or implemented. While to define the standard for these wireless technologies you have another authority. These include,. ITU International Telecommunication Union co-ordinate spectrum allocation and regulations among all of the regulatory bodies in each country.
A license is not needed to operate wireless equipment on the unlicensed frequency bands. For instance, a 2. IEEE A wireless distribution system allows the wireless interconnection of access points in an IEEE The IEEE Institute of Electrical and Electronic Engineers Standard comprises a family of networking standards that cover the physical layer specifications of technologies from Ethernet to wireless. The IEEE For instance, It is used for transmission over short distances at up to Mbps in the 2.
Similarly, one can have an extension to Wi-Fi alliance ensures interoperability among The certification includes all three IEEE Network security remains an important issue in WLANs. As a precaution, random wireless clients must usually be prohibited from joining the WLAN. While implementing a WLAN, access point placement can have more effect on throughput than standards. The efficiency of a WLAN can be affected by three factors,. Step 1 Validate pre-existing network and Internet access for the wired hosts, before implementing any wireless network.
Step 2 Implement wireless with a single access point and a single client, without wireless security. It can connect to the local wired default router and browse to the external internet.
A local area network is confined to a smaller area. In this CCNA tutorial for beginners, we will see how a computer on the different network communicates with each other.
A router is an electronic device used to connect network on LAN. It connects at least two networks and forwards packets among them. According to the information in the packet headers and routing tables, the router connects the network. Computer over the Internet communicates through an IP address.
Each device in the network is identified by a unique IP address. These IP addresses use binary digit, which is converted to a decimal number. We will see this in the later part, first see some basic binary digit lessons. Binary numbers include numbers 1,1,0,0,1,1.
