1 Computer Languages

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

3 he simplest language is called “Machine Language.” Also called “binary,” it looks like this: T

4 he simplest language is called “Machine Language.” Also called “binary,” it looks like this: T means the letter “K” in machine language.

5 That’s right. When you hit the letter K on your keyboard, all this binary code is sent to the computer and a K pops up on your screen. That’s right. When you hit the letter K on your keyboard, all this binary code is sent to the computer and a K pops up on your screen.

6 ompter language is hard to read! C

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

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

9 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. T

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

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

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

13 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 O

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

16 Inline styles Use inline styles to align your web page element: Millendez's Math Class Millendez's Math Class The code might look something like this: at New Technology High School at New Technology High School Math Classes Math Classes Class Policies Class Policies Grading Grading Appointments Appointments Safety Safety

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