PART #1 COMPUTER PORTS 1. The picture shown is from the back of the Desktop Computer. Look at the back of the computer and make sure you know what all the connectors are for. 2. Look closely at the icons associated with each connector and make sure you understand what they represent. In your Lab Report explain what the icon 10101 stands for. 3. Most computer manufacturers color code their connectors according to a standard color code to simplify the connecting of peripheral devices. 4. The diagram below is from the back of the PC Trainer. In your Lab Report label the trade names of the connector and name of typical peripheral that would connect here . See Appendix for extra information. 5. Computer ports can be categorized according to the number of wires; serial or parallel and according to the signal type; analog or digital. EE 368 – LAB# 3 Page 2 of 13

6. In your lab report list which interface on the back of the computer you think use parallel communications? 7. In your lab report list the interfaces on the back of the computer you think use serial communications? 8. In your Lab Report list, which is the preferred method for interfacing a new peripheral to a computer and two reasons why, this method is preferred. COMPUTER PERIPHERALS PART #2 - MONITORS 1. One peripheral found on all computers is the monitor. Monitors come in two main types CRT and LCD and each type has its own advantages and disadvantages although with LCD screens constantly improving they will soon outsell CRT monitors. 2. CRT monitors are analog devices and use analog signals for control through the VGA connector this connectors trade name is _______________. LCD monitors are digital and connect to a DVI (Digital Video Interface) although many LCDs utilize an analog to digital converter to allow the use of a VGA connector since this is still the most popular video connector in use. 3. Newer monitors support Plug and Play allowing the computer to detect the maximum resolution supported by the monitor and the highest vertical refresh rate possible at a particular resolution. Most users select the resolution they are comfortable with but should also check the Vertical Refresh Rate to minimize user fatigue when using the monitor for longer periods of time.

    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.
