Week Five: Advanced Networking Devices - VPN Lots of topics were discussed for this week five chapters reading, and the four chapters reading are: TCP/IP Applications, Network Naming, Securing TCP/IP, and Advanced Networking Devices. All the contents or topics provided in each chapter reading played an important role in computer networking. The purpose for this blog is that I will be picking a single topic from one of the four chapters and discuss to the best of my knowledge. Let get started with that being said! Virtual Private Networks (VPN) VPN is configurated for secure network communications. VPN hides Internet Protocol (IP) address from could-be hackers, government agencies, corporations, etc. It doesn’t matter if whether you are connected to a VPN in public, your identity will stay always remind protocoled. You put your privacy at risk when connected to a public network because that public network doesn’t have encrypt tunnel, and therefore, has no endpoints. VPN in the other...

Week Four: TCP/IP, and Routing The week four topics focuses on Transmission Control Protocol/ Internet Protocol (TCP/IP), and Routing. Both contents play an important role in the computer networking environment as we all know. Like every other technology that we heavily relied on to execute our daily activities, TCP/IP had a rough beginning. To put it into content, and be specific, TCP/IP was created by UNIX. In the early 80s, four of major players in the computer and network industry (Microsoft, Apple, Novell, and UNIX) had created their own protocol com communicating and sending data over a network. No one software or protocol could execute everything that the network required, and because of that, the four major companies decided to put together their “protocol under term the protocol suite.” The following are the lists of those protocol: IPX/ SPX represented Novell, NetBIOS/NetBEUI represented Microsoft, AppleTalk represented Apple, and TCP/IP represented UNIX. Eventually as time...
Week 3: Ethernet Basics, Modern Ethernet, and Installing Physical Network. The very purpose for this week blog is to turn our attention and focused on key networking devices and aspects like, Ethernet Basics, the Modern Ethernet, and Installing Physical Network. Ethernet Basics. The historical aspect of the network didn’t exist until the year 1973 when “Xerox answered the challenge of moving data without sneakers by developing Ethernet, a networking technology standard based on a bus topology” (Meyers, 2018). To see how dramatically the innovations and evolution of technology has progressed over the years, let take the original Ethernet for an example that used just a single pair of coaxial cable and compare it the modern Ethernet. The earlier/original Ethernet was seen as a success and transfer data at the rate of “three million bits per second (3 Mbps).” Can you ever imagine having to setup a network in this era that transfer data at such rate? The earlier Etherne...
Week Two: Cabling and Topology The discussion topic for week two in very important in that it focused on “whether there are too many standards organizations attempting to regulate the networking field, and if some form of consultation is necessary for governmental of larger international bodies should be formed in respective to manage standards.” The purpose of Standards organizations is set-up the blueprints for reliable, interoperable communications among various networks throughout the universe, and the top leading standards organizations as: 3 rd Generation Partnership Project (3GPP) – the purpose for 3PP is to develop protocols that are used for mobile telecommunications. 3PP is well known for its evolution and maintenance of Global System for Mobile (GSM), 2G, and 2.5G standards, General Packet Radio Service (GPRS), Enhanced Data-rate for GSM Evolution (EDGE), Universal Mobile Telecommunications System (UMTS), 3G standards, High Speed Packet Access (HSPA), and HSPA+. ...
CompTIA Network+: Network Management & Infrastructure
Week One: Entry Blog. Hello to all, my name is Edward Cooper, and I was born and raised in Monrovia, Liberia, Africa. I came to the United States, November of 1996, and I reside in the beautiful state of New Jersey. I love working with different types of technologies and I just got through building a brand-new Personal Computer last month as I was pursuing my certification in Comp & Network Security Fund (CompTIA Security+), and Comp & Hardware and Software Mgmt. (CompTIA A+). I am currently taking a class in both Computer Server Environments (CompTIA Server+), and Network Mgmt. & Infrastructure (CompTIA Network+). Other than Windows Server that I have had some experiences (installed and configured) working with, I have not had experience with other vendors’ server platforms. Speaking of server, I have some experience when it come to computer networking and I was able to build a home network (LAN) with four computers, Windows server, routers hubs, and a sw...
Week 12: Security and Operational Procedures. What a great learning journal it has been. The end and final week of the twelve weeks of classes. I never has the full pleasure of communicating with my professor, but the few times I was able to, my professor responded as quick as he could. With that said, the last and final topics for this week twelve is based on “Security and Operational Procedures.” The threats in posted to any personal computer or a network always occurred from two different direction: malicious or accident. Always expect and remind yourself that a problem is going to occur at any time which can affect your computer. Whether in homes or at work, computers are used for all sort of activities, mostly involving data. We work with data whenever we used computers, therefore, whatever security mechanisms and operational procedures you find helpful should be implement and execute affectively for the purpose of safeguarding your data. Failure to follow proper secu...
Week 11: Printers and Multifunctional Devices The focus for this week topic point to Printers and Multifunctional Devices-which is essential to our everyday operations, and that brings me to the weekly objectives for this week eleven aspects. · Define printer types and features, · Learn how to install and share printers and how to manage printer features, add-on devices, and the printer queue. · Discuss routine maintenance tasks necessary to support printers. · Troubleshoot printer problem. There are various types of printers with different features because there are more than one manufactures (HP, Dell, Samsung, Canon, etc.) that produces printers. Technology has changed the way we used printers, and thanks to all the multifunctional that has added. Over decades ago, printers had far les...
