Building Ethernet LAN On this module you are going to a networking term in PC and printers are just know as end-user devices, hosts, or it's just devices. As i already mentioned that a geographically limited network is called a Local Area Network or LAN. In Ethernet, we can see that it defines rules such as frame format as well as how computers communicate with each other over a single wire shared by all devices on network. When it comes to Ethernet standards that there is the protocol that controls access to the network and finally there is frame format. Ethernet was originally deployed with multiple computers connected to the same physical wire or cable. This physical network topology or layout is is called shared bus or network segment receive it. But if there is break in cable, devices can no longer communicate. By the way the network segment refers to the group of network devices that compete with each other for access to the wire. When, we need to connect to...

OSI Model Now we will move on to OSI model reference that is Open System Interconnection these networks that provides guide lines that provides to communicate with computers over network. These are not specific procedure or protocols because these functioning by step by step process that must be completed at each layer that the computer communicate over a network. Physical Layer The lowest layer of the OSI Model is concerned with electrically or optically transmitting raw unstructured data bits across the network from the physical layer of the sending device to the physical layer of the receiving device. It can include specifications such as voltages,  pin layout, cabling, and radio frequencies. At the physical layer, one might find “physical” resources such as network hubs, cabling, repeaters, network adapters or modems. Data Link Layer At the data link layer, directly connected nodes are used to perform node-to-node data transfer where data is packaged into fra...

Overview on Juniper certification In this module your going to learn for JNCIA cert on these following program; How Network works in detail specific technologies and protocols to be used How does data gets anywhere Now we will move on to networking. What is Networking ? A networking is nothing but a communication between to end points on the internet. That this internet is just a bunch of interconnected machines (i.e., computers or printers) that each using their own private addresses (i.e., IP address).  To function properly, the network must have a set of established protocols standardized rules for the format and exchange of messages. These protocols allow the linked computers and devices to interpret the signals they receive and to engage in meaningful “conversations” in order to accomplish tasks on behalf of users.  For example, if two computers are linked, one might signal “ready to send” and wait for the other to signal “ready to receive...
