Parts of a computer:



8 essential parts:
1. Case: box around all the parts

- easy to open up
-large enough to fit everything into it
- large exhaust fans
- compatible with motherboard
  
2. Power Supply: 
Provides power to motherboard and expansion slots.
 - adequate wattage

- modular plugs - manage cables
Fan - heat management.  

 



 3. Motherboard:



Ties all the parts of the computer together
 - ties together processor, memory, power supply, video cards, keyboard, mouse, sound, monitor etc.






 -AGP - Accelerated Graphics Port channel for attaching a video card

 -RAM - Random Access memory - temporary data storage that can be accessed in any random order.  Temporary - is gone if you shut the computer down (if you did not save your work, and the computer shuts down, it will be gone because it was only in RAM.)

- ROM - read-only memory. Permanently stored data. ROM stores your computer's configuration is and is necessary to boot the operating system.

 -PCI - Peripheral Component Interconnect – attach hardware devices like network cards, sound cards, modems etc.

 -ISA Industry Standard Architecture IBM computer bus   

- Bios Basic Input/Output system, or basic integrated operating system, performs basic functions like booting and keyboard control.  

- CMOS battery – stores the system time and CMOS BIOS settings when computer is off (Complementary metal oxide semiconductor)
- EIDE - Enhanced integrated drive electronics, or ATA storage device connector, like hard disks & floppy drives

 -CPU - Central Processing Unit


PCI express - Peripheral Component Interconnect Express serial expansion bus
SATA - Serial ATA (Advanced Technology Attachment) bus interface that connects bus adapters to storage devices like hard disk drives and optical drives.

 ATX - default form factor, full-size ATX board is 12 × 9.6 in (305 × 244 mm).

 DDR - double data rate RAM - high transfer rates

 HDMI (High-Definition Multimedia Interface) audio/video interface for transferring uncompressed video data

4. CPU - central processing unit, hardware in computer that performs input/output operations, decodes, and performs calculations.

Multiprocessing - more than one CPU
Multi-core processors - multiple CPU's on single chip

located next to big fan, most expensive part of computer
  • Intel - LGA (land grid array) socket, no pins, just gold contacts
  • AMD - pins 

 

  • Fan - important to keep CPU from overheating!!


5. Memory

DIMM - dual in-line memory module,  series of dynamic random-access memory integrated circuits.
RAM - Random Access Memory
temporary memory that only works when the computer is on, then it is flushed out.

6. Video Card
DVI - Digital Visual Interface




Discrete video card - separate from what you get on motherboard

PCI  (Express) -  Peripheral Component Interconnect, serial computer expansion bus

  • serial communication sends data one bit at a time, sequentially, over a communication channel or computer bus.

  • parallel communication,  several bits are sent as a whole, on a link with several parallel channels.
 
7. Storage (HDD/SSD) - AKA hard drive
Permanent memory storage (does not disappear when computer is turned off, like RAM/DIMM)
Mechanical hard drive.  Two different types:

  • HDD - hard disk drive -uses rapidly rotating "hard" disks coated with magnetic material.  Magnetic heads arranged on a moving actuator arm read and write data to the surfaces. Data is read in a random-access manner, meaning individual blocks of data can be stored or retrieved in any order rather than sequentially.  



  • SSD - solid-state drive/solid-state disk
 - no moving parts, no actual "disk" of any kind,
- no motors to "drive" the disks, -
- data storage device using integrated circuit assemblies as memory to permanently store data
- fast and quiet


    8. Optical Drive
    reads and writes to CD's, DVD, and Blue Ray disks.
    CD - "compact disk", originally created for music, expanded for use with storing data.
    • CD-ROM: Read-Only Memory
    • CD-R - "Recordable" is a Write Once Read Many (WORM) optical medium
    • CD-RW "re-written"



    DVD "Digital Video Disc" or "Digital Versatile Disc", originally for videos, expanded for use with music and other data.  
     
    Blue Ray - can store video and audio with greater definition

    I/O  (Input Output)
    keyboard, mouse, USB, Printer, Monitor etc.

    BIOS - Basic input output system for loading
    UEFI - Unified Extensible Firmware Interface
    replace BIOS in newer computers, interface between OS and firmware.
    OS - Operating System - software that manages hardware resources - links programs with hardware. (UNIX, Solaris, Linux, Mac OS X, Microsoft Windows)

    Program - instructions to perform a task.

    Measurements:

    ¨Bit (b) – Binary Digit, value of 0 or 1
    ¨Byte (B) – 8 bits
    ¨Kilobyte (KB) – 1024 bytes (210 bytes)
    ¨Megabyte (MB) – 1024 * 1024 bytes (220 bytes)
    ¨Gigabyte (GB) – 1024 * 1024 * 1024 bytes (230 bytes)
    ¨Terabyte (TB) – 1024 * 1024 * 1024 * 1024 bytes (240 bytes)

    Engineering Project Report & Presentation

    Review “Writing as an Engineer”
    http://engr1304.blogspot.com/2014/01/writing-as-engineer.html

    The end of the semester is approaching fast!  I am trying to give you enough time to do classwork in class, so that you will have time outside of class to get your project done.

    Reminder: Class attendance is 10% of your final grade.  It is very important that you make it to class, and make it to class on time!

    April 24& 29 Project presentations.
    May 1st       Review for final.    Final Exam: May5-11
    Grades due in MyLoneStar (4 pm) May 13


    Consider making a blog to share and gather info for your group rather than relying on emails. Just go to blogger.com, or blogspot.com, sign in, and start posting.  Let one person be in charge of the blog, aloow comments for everyone else to add and edit information.  Another alternative - create a fb page.  

    Your group report should have the following sections:


    Heading:
    Centered on page: Name of your product (pick a catchy name!)
    List team member names with their responsibilities, with date, and" LSC ENGR Project".




    The No Totter Water Potter
    Jack  – Research and Design, written report.
    Jill – Construction & Testing
    Mary –  Construction & Testing
    Joe – Compiled data, created graphs, tables, and diagrams.

    1. Introduction (5 points)Briefly state the product you decided to create, what need it will fill, who it will be marketed to, and why you chose this product.

    ie – Jack and Jill have refused to go up the hill, so we created a clean drinking water  transportation and containment system to deliver and store fresh hill spring water right inside their own house.

    2. Research and Background information (10 points)    As can be seen on the map in figure 2.1, on top of High Hill, at the headwater of Slippery Stream, lies Clearwater Spring.   The spring water is purified through a natural filtration process where the groundwater seeps through rocks and soil (see ref #1).  Etc. etc.  This water was last tested on Nov 28, 2012 by AAAEnviroWet and was found to be exceptionally pure (2).


    Notice - figures are referred to and discused within text.
    Figures have figure captions with a short description of what the figure is on.
    References are #'d, full reference at the very end of the report, in the order that they appear in the report.
    Just format everything like your textbooks are formatted - with sections, subsections, figures, tables, etc.
    .
    3. Product specifications, diagrams, pictures, and user instructions. (25 points)
    Older lead pipes on the High Hill property will need to be removed, and replaced with insulated polyvinyl chloride piping installed according to rhyme building code specifications (2).   A splitter valve will divide the water flow into an above ground black solar hot water pot, and an underground cold water pot where it is stored until needed as shown in figure 3.1.  

    4. Testing ,  testing methods,     modifications, and operation procedures.   (25 points)
    Water purity, pressure, and temperatures were tested throughout the system at various weather conditions as shown in table 4.1.  After consideration of the data, a pressure relief valve was installed to prevent rupture of the solar heater during hot summer months, and an air injection line was installed to blow water out of lines susceptible to freeze in the winter.   Operating procedures for both summer, and winter months are presented below….
    .
    5. Observations, Results and Discussion (25 points)The variable water flow rates resulting from seasonal weather changes in table 5.1 were used to calculate the storage tank size needed to ensure a constant water supply through the entire year.   Seasons weather changes also affected the solar water heater temperatures, and additional  gas or electric heating may be required in winter months.
    .
    6. Conclusions, suggestions for future work. (10 points)Jack and Jill’s new “No Totter Water Potter” network is a vast improvement over the previous bucket and muddy path water transportation  system.  Although this new system has many advantages, the spring snowmelt water runoff poses a possible threat to the water purity in late April and May, and future mitigation for this is strongly suggested.  Etc.

    Reference Section
    Correctly formatted, and numbered.


    Use the writing tutoring center!
    http://engr1304.blogspot.com/2014/03/tutor-schedule.html



    Presentation:
    Short, sweet, simple, entertaining.


    Total presentation should be no longer than 10 minutes.  Bring a USB drive with diagrams, slides, videos of your diagram, etc. to share.  Presentations will be graded by your class peers on enthusiasm, clarity, organization, body language, voice projection, visual aids, content, etc.



    Practice makes perfect!  For the ethics unit, each groups will choose a case study of an engineering disaster to present.  This will give you a heads-up on what presentation skills you need to fix before your project presentation.
