Overview of Network Layer Functions

Overview of Network Layer Functions Many protocol models have existed over the years, but today the TCP/IP model dominates. And at the network layer of TCP/IP, two options exist for the most protocol around which all other network layer functions revolve: IP version 4 (IPv4) and IP version 6 (IPv6). Both IPv4 and IPv6 define the same sorts of network layer functions, but with different details. This chapter introduces these network layer functions for IPv4, …

Sending Ethernet Frames with Switches and Hubs-infosavvy

Sending Ethernet Frames with Switches and Hubs

Ethernet LANs behave slightly differently depending on whether the LAN has mostly modern devices, in particular, LAN switches rather than some older LAN devices called LAN hubs. Basically, the use of more modern switches allows the use of full-duplex logic, which is much faster and simpler than half-duplex logic, which is required when using hubs. the final topic during this chapter looks at these basic differences. Sending in Modern Ethernet LANs Using Full Duplex Modern …

Sending Data in Ethernet Networks

Sending Data in Ethernet Networks Although physical layer standards vary quite bit, other parts of the Ethernet Networks standards work  the same way, no matter the sort of physical Ethernet link.Next, this final major section of this chapter looks at several protocols and rules that Ethernet uses no matter the sort of link. especially , this section examines the details of the Ethernet Networks link layer protocol, plus how Ethernet nodes, switches, and hubs forward …

Building Physical Ethernet Networks with UTP-infosavvy

Building Physical Ethernet Networks with UTP

For this second of three major sections of this chapter, I focus on the individual physical links between any two Ethernet nodes. Before the Ethernet network as an entire can send Ethernet frames between user devices, each node must be ready and ready to send data over an individual physical link. This section looks at some of the particulars of how Ethernet sends data over these links. This section focuses on the three most ordinarily …

Overview of Network Security Objectives

Overview of Network Security Objectives this blog is based on Understanding Network and Information Security with it’s objective Confidentiality, Integrity and Availability etc. Understanding Network and information Security Basics Security is very important, and therefore the lack of it risks financial, legal, political, and PR implications. This section covers a number of the concepts, terms, and methodologies employed in preparing for and dealing with secure networks. Network Security Objectives When considering networks, you’ll view them …

Introduction-of-OSI-Networking-Model

Introduction of OSI Networking Model

Introduction of OSI Networking Model this blog is written on OSI Networking Model with it’s layer description as well as function and compared OSI with TCP/IP model. OSI Networking Model At one point within the history of the OSI model, many of us thought that OSI would win the battle of the networking models discussed earlier. If that had occurred, rather than running TCP/IP on every computer within the world, those computers would be running …

Overview of the TCP/IP Networking Model

This blog is on TCP/IP networking model in that Overview has given as well as there different layer has been explained. Overview The TCP/IP model both defines and references a large collection of protocols that allow computers to communicate. To define a protocol, TCP/IP uses documents called Requests For Comments (RFC). (You can find these RFCs using any online search engine.) The TCP/IP model also avoids repeating work already done by another standards body or …

Introduction to TCP/IP Networking

This blog is on TCP/IP Networking, you can know here more about Networking, it’s model and History Leading to TCP/IP with description. Introduction to TCP/IP Networking So, you’re new networking. Like many of us , your perspective about networks could be that of a user of the network, as against the network engineer who builds networks. For some, your view of networking could be supported how you use the web , from home, using a …
