She showed us how to get to devise mangager through control system. Then she showed how to reboot a system and take away ports, and then put them back. A real picture of a USB port was also shown. On board means it is attatched to the mother board of the computer. A USB port can also be used for Bluetooth. She is going to run a setup program. This installs functions of the device and drivers. You run the setup with the device! They can be tricky and when you reboot, it might not go as well. She went onto to firewall next. Transfers data at 800 MBPS. The Firewall 400 goes up to 400 MBPS. She uses it for external back up devices. Firewall uses 30 volts of power. For installing the devices is simply pluggin it in and..BOOM. You're done. INfered and Bluetooth do not require wires. They can transfer things from 10 to 20 ft. Bluetooth goes up to 10 Meters. To install it you usually have a password and it pairs to something. RCA connector is seen on a back of a tv or vcr. yellow is video, red is for right speaker, white is left speaker. If you know the colors and what they stand for, you'll be better off. MIDI connectors are old. Anything you take out of a computer is an import device, ex mouse. As soon as you plug the device in , it should be ready to go. then moved onto chap. 10. CDROMS and MP3players are all different storage. She also showed us the inside of a harddrive!

If vdeo isn't working then there are things one can check. If it doesn't work it may not be plugged in or the cable is bad. if it flickers, refresh it. If it is blurry it may mean your monitor isn't working. It can be the same with Sound Cards. No external sound could be because the speakers are not plugged in. If the sound is distorted it could be because the volume is too high. Make sure you have a microphone if you wat to capture sound. Hardware Resource Interupts: gets the CPU attention. It pauses current activity that is going on. IRQ is an interupt request. They're 16 IRQs. To assign an IRQ one can plug and play or us DIP switches or Jumper Blocks. Or you can use a software Interface. We can go to resources and then choose. Then you can't overlap the IRQ's.DMA = Direct Memory Address. It allows hardware to access memory. It is being "fased" out. Comm Ports take place in a Serial Transmission. Motom cable is where you cross the cables. Pin 1 to something else. A straight through cable is where its Cable 1 to cable 1. Cable 2 to cable 2. Each Pin number has its own connection. The pins can't be broken, otherwise they won't work. Parallel Ports send more then 1 bit at a time on a parallel channel. This is very common with printers. They have expansion cards that you can buy. The parallel ports require resources. Then she talked abot Printer cables. Pc Input Devices were next. Examples: Keyboard, Mouse, Trackball, Trackpad, Pens (styli), and Touch Screens. Most of the time the Keyboard and Mouse cable are color coded (purple for keyboard) (green, for mouse).
Somtimes the cable can fit in another keyboard part, but it will not function correctly. Another Input Device is a Barcode reader. She rambled on and on about Her different USB types that she personally uses. USB is popular because of the speed it uses.

Starting Point: Disk 3
Started #3 DVD!! yay.....*caugh. Just kidding. We started talking more about buses, aka Pci's. When you put in a card, you have to unplug the computer and drain the power so you don't hurt yourself. We have to handle the cards by the edges/sides we don't want to touch the parts that go into the PC. IRQ has a numeric address it helps the CPU identify the interrupting source. All devices need their own memory. DMA channels stand for Direct Memory Access. Then she talked about the Device Mangager. We are able to see all the different devices and what type of IRQ it uses.

Drivers: some are provided for you, and others you might have to install. Then she went on to the Pc's. You first have to go to the start menue.Then to control panel, then to sound and audio. Sund Card Connecters are your microphone/speaker etc! Also handle them on the edges and don't bend any of the delecate things on he piece of hardware. She talked alot abou different commands as well. There are 7 different types of speed standards. She took a laptop and showed us what a mini PCI looks like. The screws are very small compared to normal ones. OMG!! Mrs.Happy eats computer ribbons!! She says they come in different shapes, sizes, and flavors!! hahaha!!! This was a very interesting day with Mrs. Happy! :)

Today she talked about IRQs. There are common ones. You can identify a section of the shared memory. and the devices use it to transfer data to the main memory.
She then talked about DMA-Direct memory access. She covered a Base memory Bios. I got to see what DIP switches and Jumpers look like too. They do not just flip on and off like a light switch. Then we talked about the ISA expansion Bus Slot. It looks exactly as it sounds. this is either a 32 bit o64 bit bus. One can have up to 5 slots per system.
Then she said that there is a new standard called PCIe. this is newer and uses serial communication. This was a very interesting lesson.
