CompTIA A+ Essentials 220-901, 220-902

Course Overview

In this course I learned about how a computer is put together and how all the components of a computer work together to make it function correctly and efficiently. I learned about motherboards, RAM, CPUs, expansion slots and cards, graphics cards, components, peripherals, networks, and all the components that make a computer function. Basically I learned about the guts of a computer its systems and how each one of these plays a vital role in its connectivity, function, and the individual or organizational computing experience. I learned troubleshooting methods for a variety of situations involving desktops, laptops, hybrids, tablets, phones, and peripheral devices. I learned about networks and how they function. Their different parts and protocols and how they work together to securely transfer information to each other. I was taught about security issues facing computer system and how to guard a system from them. If a system does become infected I learned how to diagnose, quarantine, and repair the effected system. I was taught about installation of software and how to install and upgrade hardware and software so that they function properly. I learned that through being vigilant and keeping up with the latest software and security protocols and applications I can keep a system safe and running. Knowing how to trouble shoot a system and find the problem quickly comes with knowing system features, programs and protocols that are in place to provide an effective operating system for personnel to use.

It has been a great learning experience going over operating systems, systems security, networks, network security, and how to set up a system to make it meet the needs of the organization and the end user. An operating system has many integrated parts that place it in a position of control over every aspect of what a user does. As an IT professional knowing how to use the different tools that an operating system has including the command prompt located within any type of operating system can provide control and diagnostic power that can reach deep into the most complex problems to discover and fix them. The tools are there and it has been a delight to learn them and practice using them in this course.

This course has taught me about operating systems and how to install trouble shoot and repair them. It has been interesting to see all the different parts of an operating system that make it possible to diagnose and figure out what is happening and how to correct potential problems. The security and monitoring aspects of OS’s are fascinating. As an administrator you can track everything a person does on the system and find potential failures in security and protocols. The amount of though and programming that has gone into operating systems makes them masterpieces and works of art. From my point of view they have thought of everything.

Course Reflection:

I have learned that there is a lot that is involved in computer system and how they function. The best way to keep a system safe and up to date is to keep learning about the latest programs and hardware that can make a system more secure, efficient, and effective in the role it is designed to functioning in. The job of IT is ever evolving and the learning process will never end. There are always new applications or different ways of doing things that make a system more reliable or more secure. The threats that face a system are greater now than ever before and knowing what to do to keep a system safe from inside and outside threats is a never ending process. Proper education for me and also for the people I work for is a vital part of securing a system and making it function properly. I have learned that this is a challenging opportunity to accept, but I also know that challenging opportunities bring growth and knowledge.
