Tutorial 9

Tutorial 9 is about security on the internet and the web. The tutorial starts off by talking about different types of security like physical and logical, and the different measures you can take to secure not only your computer but also your identity. Crackers are usually programmers that use their skills to obtain unauthorized entry into computers and networks. They are usually out to obtain information like credit card numbers, addresses, and others forms of people’s identities. Identity theft occurs when someone like a hacker obtains your social security number, credit card numbers, passwords, or date of birth with out permission and then use the information to purchase items, open bank accounts, or get new credit cards.

Tutorial 8

In the beginning of Tutorial 8, it talks a great deal about markup languages and the most common of those markup languages known as HTML. HTML is the language a browser uses to interpret and display content of a website. The book also talks a little bit about planning and creating an HTML document so you will be able to publish it online. Also once you create it, how you can add certain images and designs to make your document unique. I recently discovered what the difference between raster and vector graphics was when my team tried to have some jerseys made. We took a raster type image and the t-shirt maker was unable to use our design unless we had a vector style graphic.
