CHAPTER 1 1 The Path of the PC Tech In this chapter, you will learn how to • Explain the importance of gaining skill in managing and troubleshooting PCs • Explain the importance of CompTIA A+ certification • Describe how to become a CompTIA A+ Certified Technician Computers have taken over the world, or at least many professions. Everywhere you turn, a quick dig beneath the surface sawdust of construction, the grease of auto me- chanics, and the hum of medical technology reveals one or more personal computers (PCs) working away, doing essential jobs. Because the PC evolved from novelty item to essential science tool to everyday object in a short period of time, there’s a huge demand for a workforce that can build, maintain, troubleshoot, and repair PCs. The Importance of Skill in Managing and Troubleshooting PCs The people who work with computers—the Information Technology ( IT ) workforce—do such varied jobs as design hardware, write computer programs that enable you to do specific jobs on the PC, and create small and large groupings of computers— networks so people can share computer resources. IT people built the Internet, one of the most phenomenal inventions of the 20th century. IT people maintain the millions of com- puters that make up the Internet. Computer technicians (or PC techs , as those of us in the field call each other) make up the core of the IT workforce. Without the techs, none of the other stuff works. Getting workers with skill in building, maintaining, trouble- shooting, and fixing PCs is essential for success for every modern business. In the early days of the personal computer, anyone who used a PC had to have skills as a PC tech. The PC was new, buggy, and prone to problems. You didn’t want to rely on others to fix your PC when the inevitable problems arose. Today’s PCs are much more robust and have fewer problems, but they’re also much more complex machines. Today’s IT industry, therefore, needs specialized workers who know how to make the machines run well.

CompTIA A+Certification All-in-One Exam Guide 2 Every profession requires specialized skills. For the most part, if you want to get or keep a job that requires those specialized skills, you need some type of certification or license. If you want a job fixing automobiles, for example, you get the Automotive Service Excellence ( ASE ) certification. If you want to perform companies’ financial audits, you get your Certified Public Accountant ( CPA ) certification. Nearly every profession has some criteria that you must meet to show your compe- tence and ability to perform at a certain level. Although the way this works varies widely from one profession to another, all of them will at some point make you take an exam or series of exams. Passing these exams proves that you have the necessary skills to work at a certain level in your profession, whether you’re an aspiring plumber, teacher, barber, or lawyer.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
