PAN is used for using the devices belongs to one person or system. Personal area networkĪ personal area network (PAN) is a type of computer network. It uses IPv4 and IPV6 for addressing system. TCP/IP support connection oriented and connection less services. Some layers of OSI architecture merged for TCP/IP. It is different from the OSI reference architecture. The Internet Protocol Suite, also called TCP/IP is mostly using protocol in present time. Mostly end devices are used WLAN to access the network. Wireless LAN, also widely known as WLAN or WiFi, is the mostly used in present scenario. This article is about only networking basics. Brief description of Ethernet will be discussed later. RJ 45 connector used for connection in a network via Ethernet. It works on physical and data link layer in OSI reference model. IEEE 802 is a family of IEEE standards dealing with local area networks. Some common Protocols used in networking basics for CCNA IEEE 802 Mesh topology is created to achieve that at least one node should be always connected with any node. In Mesh topology all the nodes are connected with each other. Mesh Topology : Mesh topology is also called hybrid network topology. The best example of Ring Topology is FDDI. All the nodes are connected like a circle. Ring Topology : In ring topology all nodes are connected with each other like hand to hand a big human circle. This is the mostly used topology in today scenario. In WLAN all nodes are connected to a Wireless access point. The best example of star topology is WLAN. Star Topology: In star topology all nodes are connected with a common networking device like switch. This topology used in layer 2 data link layer of OSI reference model. The main drawback of this topology is that if backbone breaks anywhere full communication will fail. Some common Network structure or layoutsīus Topology : In Bus Topology all the devices or nodes are connected with a common medium. If any networking device going to fail the data flow does not interrupted in the network. Mash topology provides the redundancy for connectivity of devices. Generally mash topology used in most of the networks. Network topology are of many types, some of them are Bus, Ring, Star topology.Įach network topology have it’s own pro and cons. The Network topology is the physical layout of network. Network topology define that how the nodes are connect with each other. The Network Topology is the physical layout of the network. Network topology in networking basics for CCNA Ethernet works on electrical and fiber both medium. Ethernet is the common media use for connectivity of network. Some common media are electrical cable, Optical fiber cable, Wireless etc. The medium used to connect the network nodes is called transmission media. Connectivity medium in networking basics for CCNA Media of sharing information may be OFC, Cat6, WiFi, Bluetooth etc. Flow of packets depends on the bandwidth of media. this process known as data transmission over the computer network. When same packets received at destination packets are reassemble and reform the information. The flow and control of packets controls by the protocols used in the network.Īctually the information divided in to packet at source and transmitted. The packet size is define by the networking protocols. Packets are generate and flow with the help of networking devices. Data Packets are the main thing in networking basics for CCNA. The data flow in the form of Data Packets in a computer network. Data Packets in networking basics for CCNA Nodes are the computers, smartphones in networking basics for CCNA. Sharing of resources in a network done via flowing of network packets. The shared resources may be any application, videos, images, email, data storage, printers etc. In a network devices able to exchange information with each other with the help of switch, router etc. Nodes are generally identify by network addresses or IP address. The Nodes may be servers, computer, printer, smartphone etc. The Nodes are the equipment which are connect with some networking devices. Nodes is the important term in networking basics for CCNA. Nodes or End Devices in networking basics for CCNA These all things depends on the latest technology working around us. SOHO stands for Small Office Home Office which allow to run a small business from home with online support. In today scenario the SOHO concept running all over the world. You can use the devices of your office from your home over the internet. For example you have a internet connection in your office and at home too. In today scenario some devices supports to work on the internet.
