Examples of Input Devices
Devices used to feed data and control signals to a computer. * Keyboard * Mice * Microphone * Game controllers * Scanners * Cameras

Examples of Output Devices
Output devices provide the data processed or stored by the computer. Output devices may be audio, visual, or both. * Monitors * Printers * Projectors * Speakers
Summary of Thoughts
The video exercise was very educational, I’ve always had trouble remembering what the ports name is and the number of pins it has. This is the reason I wrote all of them down, so that it would be easy for me to study and understand. The input/Output device sections made everything more clear as to what each device does and the type of ports they use.

Video Summary: the Economy of Brazil

...According to Al Jazeera English’s video, Brazil’s booming economy July 9, 2008, Brazil is reported as a sleeping giant and a powerhouse. Brazil was also recognized as having one of the fastest growing economies in Latin America based on its strengths of steady gains of investments in the country’s stock market. In 2008, Brazil’s stock market grew 10% within a matter of months. Furthermore, Brazil experienced a vigorous economic growth by far outpacing competitors in expanding their agricultural, mining and manufacturing products. They also enjoy a stable political system and an enormous amount of people available to work in their different areas of growth. According to Al Jazeera English’s video, “Highs and lows of Brazil’s economic boom” of September 30, 2007, Brazil struggled with some of the same weaknesses of other countries. Although a powerhouse within the world’s economic market, there is still a lot of work to be done within Brazil. Many of Brazil’s poverty stricken or low-income families and communities do not get to enjoy the country’s growth. Some of these families and communities live below the poverty line and simply don’t have the money to invest in the stock market. Additionally, there are even Brazilian families that do live above the poverty line but don’t earn sufficient wages to participate in the stock market because the average income in Brazil does not keep the pace that is required to meet the country’s everyday standards of living. ...

Do Video Games Kill Summary

...unbiased. Karen Sternheimer, the author of “Do Video Games Kill,” and world renowned positive psychologist Dan Gilbert, the author of “Immune to reality” challenge this idea. Karen Sternheimer used “Do Video Games Kill,” to show the underlying nature of human psychology. “The video game explanation constructs the white, middle-class shooters as victims of the power of video games, rather than fully culpable criminals. White, middle-class killers retain their status as children easily influenced by a game, victims of an allegedly dangerous product. African-American boys, apparently, are simply dangerous.”17 While biologically the same, the psychological notion that white teen killers are victims and black killers are simply evil is depicted in the media. If one is unbiased they...

Video Summary

...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 major...

...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 SRAM...

Contributors:Elyssa Tardiff, Allen Brizee. Summary: This resource describes why outlines are useful, what types of outlines exist, suggestions for developing effective outlines, and how outlines can be used as an invention strategy for writing. Four Main Components for Effective Outlines Ideally, you should follow the four suggestions presented here to create an effective outline. When creating a topic outline, follow these two rules for capitalization: For first­level heads, present the information using all upper­case letters; and for secondary and tertiary items, use upper and lower­case letters. The examples are taken from the Sample Outline handout. Parallelism—How do I accomplish this? Each heading and subheading should preserve parallel structure. If the first heading is a verb, the second heading should be a verb. Example: I. CHOOSE DESIRED COLLEGES II. PREPARE APPLICATION ("Choose" and "Prepare" are both verbs. The present tense of the verb is usually the preferred form for an outline.) Coordination—How do I accomplish this? All the information contained in Heading 1 should have the same significance as the information contained in Heading 2. The same goes for the subheadings (which should be less significant than the headings)...

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.

Video Summary

...We have two types of memory. Read only memory (ROM) and random access memory (RAM). For RAM there is Static RAM and Dynamic RAM. SRAM is faster, more expensive, does not need refreshing and is used by the CPU to store its cache memory. DRAM is used for computer memory. SIMM, DIMM, and RIMM are the three types of RAM modules. SIMMS are no longer used in today but you might see them if you’re working on an older computer. DIMMs were the first to be synchronized with the system clock, and were referred to as Synchronous Dynamic RAM (SDRAM). DDR SDRAM and DDR2 SDRAM use dual channeling. In dual channeling both slots of the DDR must be filled with the same amount of memory. With RIMM slots all the slots must be filled either with memory modules or continuity (C-RIMM) modules. Earlier RAM had an extra bit known as parity bit to check for errors. Unfortunately, it would only detect if a bit was bad or good without a way to fix it. ECC is used in modern memory to correct memory errors at the bit level and correct any problems it may find. There are magnetic, optical, and solid state storage devices. Floppy disks and hard drives are magnetic storage devices. If exposed to a magnet data loss may result. Hard drives have a 137 GB limit. You must flash the BIOS to upgrade it and it will allow it to support a larger number of hard drive addresses. The Hard drive interfaces to attach to the motherboard are PATA/IDE, SATA, SCSI, USB, and FireWire. Along with hard drives, parallel ATA (PATA)...
