Spring 2007 Computer Skills and Concepts

First eleven weeks - Back to c021.html c021.html current page (last 5 weeks)

Day #1 email note.

Class #2 summary. To be used in conjunction with the day #1 handout and with a future textbook BookOnCD Lab assignment.

Here is a link to the Wednesday binary handout that you received. You are NOT expected to understand this yet, so no worries there! :-)

Day Two email note.

The FOUR GENERATIONS of electronic digital computer are:

• First generation: Vacuum tubes;
• Second generation: Transistors;
• Third Generation: Integrated Circuits;
• Fourth Generation: Microprocessor.

1. Word Processing Olympics.

2. Techniques for the word processing task1.doc, with screen snapshots.

3. The Handout of some of the shortcuts and power user techniques.

20. (L1 cache means Level 1 cache, and L2 cache means Level 2 cache).
21. Cache is fast, RAM is slow.
22. Cache is very expen$ive compared to RAM, so you cannot have anywhere near as much cache memory as you have primary memory.
23. L1 cache is very, very, very expen$ive and you cannot have very much of it.

    However, it is lightning fast, and much closer to the speed of the CPU. It is also on the microprocessor chip WITH THE CPU.

24. L2 cache is on a separate chip from the CPU, but is much faster than RAM, but slower than L1 cache. There is much more L2 cache than there is L1 cache.
25. Cache memory requires 6 to 8 transistors for every bit that it can store. By comparison, RAM only requires one transistor for storing each bit. That is one of the reasons for the cost and the speed difference.
26. A useful link to layers of information about cache memory. Just skim for the highlights of L1 and L2 cache.

Instead of a BODY BGCOLOR= we did a BODY BACKGROUND= and used your PAINT produced graphic at the BACKGROUND graphic in a feb2.html web page file.

See solution for Quiz 2 Spring 2002 handout and 02/05 in class exercise. Just do View menu, Source command (for Microsoft Internet Explorer web browser) to see the HTML. (View menu, Page Source for Mozilla Firefox web browser application).

FRIDAY - SABIN 227 Computer Lab for Photoshop

1. Here is a link to information about sunny.uni.edu and your personal web page.

2. This link will show you the BACKGROUND= and BGCOLOR= options (known as Attributes) of the BODY tag. We did the BACKGROUND= on Friday, Feb 2nd Ground Hogs Day hands-on class.

3. How did I get this OL ordered list to be NUMBERED with Roman Numerals instead of the usual default Arabic numbers? Here is HOW TO DO THAT.

   This link will also show you how I got the week 4 numbered list (see above) to start with 20 (20, 21, 22, 23, 24, 25) instead of starting with 1 (1, 2, 3, 4, 5, 6). See the Attributes.

4. How to create ANCHORS to link to other pages, aka Hypertext links.

5. Here is a Tag Tutorial on HTML tags and how to create your first web page. TAG! You're it! :-)

6. Here is the Overview of All HTML elements you are already familiar with from our first hands-on HTML class, and from the links you explored above this one.

7. Color specifications for web pages. RGB = Red, Green, Blue graphics specifications and the mysteries of base 16, aka hexadecimal, very close 1st cousin of binary.

8. Some examples of Photoshop created gradients for use as BACKGROUND= files for the BODY tag.

REMINDER: SABIN 227 Computer Lab for Friday's class this week.

Preview this Photoshop Button making page before Friday, if you get the chance. See the Stroke dialog box, the File menu, New dialog box, the texture Channel, the New Channel icon, the Red, Green and Blue channels (besides the Alpha 1 or #4 new channel). See the Filter menu, Render command, Lighting Effects subcommand dialog box.

Also useful to preview and glance at: Adding Text to the Button. It shows the ForeColor and the BackColor icons, along with the MOVE and the TYPE tools being pointed out. Keep in mind this is an OLDER version of Photoshop, so some things will look different in the newer versions.

Relevance of MacDraw versus MacPaint issues to HTML and Structural versus presentational markup.

Nice anecdotes from 1984 period on Macdraw versus Macpaint and graphic design in its infancy.

No Photoshop class - UNI snow day

1. Download the Excel spreadsheet database introduction here. filterem.xls is its name.

2. Queries and the Movies database, especially parameter queries and expression builder.

3. Download Movies2002.mdb database by right clicking on the link. You will need this for the above exercises doing parameter queries, etc.

4. Excel examples and review for after spring break.
