 Hello Everyone!  Welcome to Week 10, and the final week of this summer's classes. This week we are answering a few questions that we were asked about this course. So, lets wrap it up!  I found this course very enjoyable and very informative. I work as a Site IT Technician for Michelin. In my profession we do a lot of networking and networking troubleshooting. This course has helped me gain a better understanding of some basic and advanced troubleshooting tips that will help me in my job.  I do not think I will continue blogging, its just not something that I find very fun to do. It is hard for me to, I guess, talk to people but talk to myself at the same time.  I wrote this in my other class for this question and I believe it fits here too. I don't think that a company would find this desirable because words on paper are just that, words on paper. I think that if you cant put what you write on paper to what you deal with in the real world, its only words and it...

 Hello Everyone! Welcome to Week 10 and the final week of our summer classes, so lets wrap things up! Something I found enjoyable about this course was brushing up on a lot of information that it haven't done in a long time and also learning more about those darn printers. There wasn't anything that I can think of that was something that I did not find enjoyable during these past 10 weeks.  My current job is a Site IT Technician at Michelin. While some of the information that we went over wasn't really in what I do in my profession, it did help me get back to the basics of things.  I am not sure if I would continue blogging about things in my life. I am not the one to try and write about the things that go on. I guess that was a little bit of the struggle for me this semester.  I am not sure as well if this would be desirable for a company or "give me more weapons in my arsenal". People can write anything on paper, but if they can't transfer what the write on ...

Hey Yall! Welcome to Week 9 of Network Management and Infrastructure. This week we covered Chapters 18 and 19. Chapter 19 covered some network threats or potential attacks against a network. Some of these threats are: Spoofing - pretending to be someone or something you are not by placing false information into your packets.      Packet/protocol abuse - the misuse of network protocols and packets to achieve unauthorized outcomes Zero-day attack - an exploit that takes advantage of a previously unknown vulnerability in software or hardware that has not yet been patched. Term Zero-day refers to that the attack happens on or before the first day the vulnerability is discovered or reported. DoS (Denial of Service) - Cyber attack aimed at making a network service, server, or resource unavailable to its users by overwhelming it with excessive traffic or exploiting vulnerabilities. The goal is to disrupt normal functioning and cause downtime which makes the services and network ...

 Hello again! Welcome to Week 9 of Computer Hardware and Software Management. This week, one of the things we talked about was connecting to the internet and the various ways to do so. Lets break down some of the ways that we can do this: Wi-Fi : Wireless networking using radio signals to connect devices to a network. Common in homes, businesses, and public spaces. Ethernet : A wired connection using cables to connect devices to a network. Known for stable and high-speed connections. Mobile Data : Internet access through cellular networks (3G, 4G, 5G). Useful for on-the-go connectivity with smartphones and tablets. DSL (Digital Subscriber Line) : Internet over standard telephone lines. Offers a reliable connection, though speeds can vary. Cable Internet : Provides internet through cable TV lines. Often faster than DSL but depends on the cable provider’s infrastructure. Fiber Optic : Uses light signals transmitted through fiber-optic cables. Known for very high speeds and reliabilit...

 Hello again!  This week we learned about cloud computing and why it is important in a company. This was a great topic because it is what I am writing my research paper about and it gave me more information that I could use in my paper. Cloud computing is a way of delivering computing services over the Internet. Instead of owning and managing physical servers, storage, databases, networking, software, and other IT resources on your premises, you can access these resources via the cloud. Some cloud computing services include IaaS(Infrastructure as a Service) like AWS and Microsoft Azure, PaaS(Platform as a Service) like Google Engine and Microsoft Azure App Services, and SaaS(Software as a Service) like Google Workspace and Microsoft 365. Benefits of cloud storage include the flexibility to adjust your resources to meet the changing needs of the company, accessibility of accessing services anywhere you have an internet connection, and the cost of paying for what you use wi...

   Hello again!  Welcome to week 8 of Computer Hardware & Software Management This week we learned about IPv6 and its uses, formatting, prefixes and suffixes, and the differences between IPv6 and IPv4. IPv6 offers so many more unique addresses than IPv4. While IPv4 offers around 4.3 billion addresses, IPv6 offers 360 undecillion addresses. That's a 1 followed by 66 zeros!!! While IPv4 is 32-bit, IPv6 is 128-bits. IPv4 is expressed in decimals 192.168.0.1, separated by dots, and IPv6 is expressed in hexadecimal separated by colons (2001:0db8:3333::5555:6666:7777:8888). IPv4 can be manually or dynamically assigned via DHCP while IPv6 is assigned automatically through stateless or SLAAC. Another big difference between IPv4 and IPv6 is the implementation of IPsec. IPsec is Internet Protocol Security. It secures communications by authenticating and encrypting each packet. It provides a framework for ensuring data confidentiality, integrity, and authenticity, transmitt...

 Good Evening, Welcome back to my weekly blog where we talk about what is going on in this weeks course work. One thing that stuck out to me this week was SONET and SDH. Lets dig a little deeper on some similarities and differences between the two.  SONET - Synchronous Digital Hierarchy was standardized by the ANSI (American National Standards Institute) defines a hierarchy of interfaces and frame formats for transmitting multiple digital bit steams over optical fiber.  SDH - Synchronous Digital Hierarchy was standardized by the ITU-T (International Telecommunication Union - Telecommunication Standardization Sector). It is largely compatible with SONET but has some technical differences.  SONET uses Optical Carrier (OC) levels to designate different transmission rates. The basic unit is the Synchronous Transport Signal (STS) which is like the European STM-1 (Synchronous Transport Module Level 1) in SDH. SDH uses Synchronous Transport Module (STM) levels to designate ...
