...Clip 1 Summary: There are three types of ports, serial, parallel, and game ports, and they have for the most part been replaced with USB ports. USB devices are hot swappable, can daisy chain, and 127 devices may be plugged into the computer USB ports. Modern mice and keyboards use PS/2 technology unlike older predated mice and keyboards, which used serial connectors, and a 5-pin bulky din connector. The network interface card is responsible for connecting your computer to your local network, a distant network, or to the internet. The dial-up modem is the slowest possible method of connecting to the internet, and it connects to the phone line; the standard speed for a modem is 56Kbps. Modern computers come with two types of video ports VGA and DVI, in addition may also have an S-Video port you may connect to the TV. SCSI connectors come with a variety of sizes, but the most common are the 50 pin connector for the A-type narrow SCSI cable, and the 68-pin connector for the p-type wide SCSI cable. IEEE 1394 also known as fire wire uses serial communication, it is very fast, hot swappable, and is especially useful when transmitting streaming media. Multimedia devices such as microphones, earphones, and speakers are usually located at the back of the CPU, but in some cases there is a second set on the front of the computer as well.

...1.05-Central Processing Unit (CPU) Video Summary #3_NT1110_Computer Structure and Logic April 17, 2014 Abstract In the video “1.05- CPU” I learned that there are two major manufacturers of CPU and they are Intel and AMD. CPU’s are organized by the motherboard system bus carries information into and out of the CPU. In the system bus the CPU is referred to as the Front side bus and usually uses a 64-bit wide data path. Inside the CPU there are controllers that manage basic functions of the CPU and control communication between the motherboard and other components within the CPU. The other components include one or more ALUs and the internal cache. An ALU is responsible for complex calculations. Communication between the controller and the ALUs uses a 32-bit internal bus. The bus system that supports the communication between the cache and the ALUs controller is the backside bus. The CPU speed is measured in GHz. There are several ways of measuring speed. The speeds differ inside and outside the processor. System bus speed is measure in MHz . The system bus speed is the actual factor that will control the speed of your computer. The ratio between processor and system bus is known as the multiplier. In older setting you may have to configure the multiplier in the CMOS setting. Multiprocessing is the ability to perform multiple functions simultaneously. True Multiprocessing requires multiple processors. Dual Core processors is another way of multiprocessing. Cache uses......

Video Summary

...Video 1.07 talked about different ports and connections on a computer motherboard or integrated card. Serial ports are male and have 9 to 25 connector pins. Parallel ports are female and have 25 connector pins. Serial connections send information one bit at a time while parallel connections send information 8 bits at a time. Game ports are female and contain 15 pins in 2 rows. Modern mouse and keyboard connections are PS/2, USB, or wireless. NIC connections convert parallel communication to serial and use an RJ-45 connector. A modem connection uses an RJ-11 connector and converts analog signals to digital signal and back. There are three types of video connections: VGA, DVI, and S-video. USB, or Universal Serial Bus, is hot-swappable, which means you can plug it into the computer while it is running and it will automatically configure without having to reboot. There are two types of SCSI connections: Narrow SCSI which is Type A with 50 pins, and Wide SCSI, which is Type P with 68 pins. IEEE 1394 or Firewire is Serial, fast, hot-swappable, and is used for streaming media. Last there is Multimedia which consists of your microphone, speaker, and earphone jacks.

...Unit 3 Assignment 1: Video Summary 1 2) Video one talks mostly about ports and the different kinds of ports that are used in computers today. It also covers what a modem is, its uses, and its speed. Video one teaches us what the difference of a wide SCSI and a narrow SCSI. The video shows all the different ports with all their pins and tells us whether they are male or female. One thing I have definitely learned from this video is what USB stands for and what it actually is. I also learned the difference between USB 1 and USB 2. Video two had a lot to do with computer displays and the different types of screens. In video two I learned the difference between a CRT display and a LCD display, it also talks about what is in both of them. It then goes into the contrast ratio and how the bigger the ratio, the better the video or the display is going to be. I always saw resolutions in my computer but I never knew what they stood for. I now know the standard resolutions and how they work. The video also talks about the video card and if you were building a computer how to know which video card would be worth buying. Video 3 goes into depth about printers and the three most common printers today. It talks about the differences between Dot Matrix, Inkjet, and Laser printers. Since Laser printers are very different from the other two, it went into further depth of the laser printer. The video teaches us multiple ways of how a laser printer can be cleaned. It also tells us......
