  2. C omputer language is what machines use to communicate with each other.

  3. T he simplest language is called “Machine Language.”Also called “binary,” it looks like this: 000000 00001 00010 00110 00000 100000 01010 10101 01101 0001

  4. T he simplest language is called “Machine Language.”Also called “binary,” it looks like this: ..means the letter “K” in machine language. 000000 00001 00010 00110 00000 100000 01010 10101 01101 0001

  7. S o programmers use a translation tool called an “Assembly Language” that uses names instead of numbers that is more user friendly.

  8. F or instance, when a programmer types “mov al, 061h” it means move the hexadecimal value 61 (97 decimal) into the processor register with the name "al".

  9. T hat’s easier than typing thousands of 1’s and 0’s, but it’s still very difficult for all but the most Hard Core nerds to comprehend.

  10. H igher-level language translates still further complex *p = NULL; abs_p = sqrt (p->real * p->real + p->im * p->im); asc_^ x = [n/> 01] Beginning to recognize some words?

  11. T he computer language you are learning is called HTML. They are known as “4th generation” higher-level languages because they are at least 4 steps above machine language…

  12. E very keystroke of a 4G language contains thousands of bits of information.

  13. O f course, the ultimate goal is a language that approximates human words allowing us to speak our instructions directly into the computer. Then we’re all doomed. -Sarah Connor

  14. Inline styles • Inline styles are HTML codes that that change the elements in a page. • HTML supports six heading styles, numbered h1 through h6. • The code might look something like this: <h1> Millendez's Math Class </h1> • h1 is really big, h6 is really small…

  15. <h1> Millendez's Math Class </h1>

  16. Inline styles • Use inline styles to align your web page element: • The code might look something like this: <h1 style =“text-align: center”> Millendez's Math Class </h1> <h2 style =“text-align: center”> at New Technology High School </h2> <h2> Math Classes </h2> <h2> Class Policies </h2> <h3> Grading </h3> <h3> Appointments </h3> <h3> Safety </h3>

  17. Elements • Web Page Elements are important to understand because you can assign “attributes” to them. • The code might look something like this: <p id=“title”> High School </p> • “title” is the attribute that will be applied to all the content contained within the tags. • “Quotation Marks” are required for attribute values.
