  • High School Degree
  • What's Inside the Desktop PC
    • Video ports a computer might have include the VGA, S-Video, DVI, DisplayPort, and HDMI ports. Other ports include a network, sound, S/PDIF, USB, FireWire, eSATA, and PS/2 ports.
    • Internal computer components include the motherboard, processor, expansion cards, DIMM memory modules, hard drive, optical drive, floppy drive, tape drive, and power supply.
    • Form factors used by cases, power supplies, and motherboards are the ATX and microATX form factors. The form factor determines how the case, power supply, and motherboard fit together and the cable connectors and other standards used by each.
    • Power connectors used by the ATX and mini-ATX form factors include the 20-pin P1, 24-pin P1, 4-pin and 8-pin auxiliary motherboard, 4-pin Molex, 15-pin SATA, 4-pin FDD, 6-pin PCIe, and 8-pin PCIe connectors.
    • Standards used by hard drives and other drives to interface with the motherboard and power supply are serial ATA (SATA) and parallel ATA (PATA). The PATA standard is also called the IDE standard.
  • Protecting Yourself and the Equipment against Electrical Dangers
    • Units used to measure electricity include volts, amps, ohms, joules, and watts.
    • Microcomputers require direct current (DC), which is converted from alternating current (AC) by the PC's power supply inside the computer case.
    • A power supply and CRT monitor contain dangerous charges even when unplugged. PC support technicians consider them to be field replaceable units and you should not need to open one.
    • Never use water to put out an electrical fire. Use a Class C fire extinguisher rated for electrical fires.
    • Equipment to protect computer components against ESD includes a ground bracelet, ground mat, antistatic bags, and antistatic gloves.
  • Tools Used by a PC Repair Technician
    • Special tools a PC support technician might need include a POST diagnostic card, power supply tester, multimeter, and loopback plugs.
    • A Material Safety Data Sheet tells you how to handle chemicals and includes physical data, toxicity, health effects, first aid, storage, shipping, disposal, and spill procedures.
    • Be careful to not lift a heavy object in a way you can hurt your back, and make sure cables are not trip hazards.

Hello my name is Anthony S. Ababat and I’m looking forward to working with you at Udemy. I grew up on the tropical island of Cebu in the Philippines, I settled in California in March of 2000. In February of 2006, I've acquired my Master’s in Business Administration (MBA) degree at ITT Technical Institute and graduated with Highest Honor. I’m a licensed Electronics and Communications Engineer. I have certificates in the following areas; A+ Professional, Network+ Professional, Computer Service Technician, Network Systems Technician, Electronics Technician (in Telecommunications). In addition I hold licenses in C-7 Low Voltage Systems and C-10 (Electrical Contractor). At present, I’m supporting Verizon project doing Fiber Optic Installation in the Southern California area (Ontario, Pomona, Long Beach, Santa Monica and Ventura County). The contracting company’s website is www.fibertronics-inc.com

My guiding principle in life is to share and provide the best of what we can offer to this world, so when we move on, we will have left behind a better world for those who follow. Currently, I live in San Bernardino, California. San Bernardino is part of the Inland Empire (IE) in California. My family includes: my wonderful wife Grely, and three children; Venice, Sweden and Rome.

Besides my professional activities I enjoy time with my family, playing chess, riding bicycles, working out and reading books.
