First thing is first: save yourself some trouble and remember that carrier sense multiple access collision detect is best referred to as simply CSMA/CD. We’ve heard some ridiculously long terms before, but CSMA/CD takes the cake. Jokes aside, this media-access mechanism is what keeps networks running. If two or more computers transmit data at the same time, we get data […]

In the previous section we reviewed several aspects of the Transport Layer. We learned a great deal of information; covering sockets, ports, TCP, UDP, segments, and datagrams. Now we will take a look at the fourth and final layer of the TCP/IP stack: the Application Layer. What Does The Application Layer Do? A lot of newcomers to TCP/IP wonder why […]

In the previous section we took a look at the Internet Layer. We took apart the IP header information, reviewed IP addresses and routing information, and briefly discussed ARP and RARP technologies. Next in line we have the Transport layer- the layer responsible for actually getting the data packets to a specific location. When we receive email, we want to […]

In the previous section, we learned about the Network Access layer. Essentially we learned more about the anatomy of a frame, physical addressing, and what exactly the physical layer accomplishes. Don’t relax yet- we still have three layers to go! What the Internet Layer Is Responsible For The Internet Layer is used to deliver data on a complex routed network. […]

In this article I attempt to explain three common network storage configurations. In today’s world everything is on computers. More specifically, everything is stored on storage devices which are attached to computers in a number of configurations. There are many ways in which these devices can be accessed by users. Some are better than others and some are best for […]

About maybe 2yrs ago I had to install and configure Dell IT Assistant Manager, which is a dell software product that allows you to manage workstations, servers, network devices….etc that are on your LAN/WAN/VPN (VPN site to site)  This cool product allowed me to view the health status of all our field servers, I managed the OS, applications, and hardware […]

In this article series, I will start with the absolute basics, and work toward building a functional network. In this article I will begin by discussing some of the various networking components and what they do. Network Adapters The first piece of hardware that I want to discuss is a network adapter. There are many different names for network adapters, […]

This article continues the discussion of networking hardware by talking about one of the most important networking components; routers. In the first part of this article series, I talked about some basic networking hardware such as hubs and switches. In this article, I want to continue the discussion of networking hardware by talking about one of the most important networking components; […]
