Applications.

Text:
When computers first came out the only application that was available was text interface. It was complicated to use if you didn't know how to use it. It had more room for other files as the files were made to a smaller size to fit more files.

Text and Menus:
Text interface did eventually have some inprovements. For example one of the improvements was menus. Arrow keys came into use so you could move around the screen instead of just having to type in all the commands. There would pop up a list of commands and you were to use the arrow keys to choose which command you wanted to do.

Web 2.0

Web 2.0 is mixing global with the local. It's a social thing that anyone can do. Web 2.0 is about searching and accessing web content. There is lots of different examples of web 2.0, such as youtube, blogging, flickr and wikipedia. They are all types of communication.
Wiki is a website that lets you edit to many interlinked web pages. Blogs and wikis are similar in ways of editing online. Although with blogs you cannot edit other peoples blogs, with wiki you can edit to mostly any website eg. wikipedia.
Wikipedia is editable to anyone meaning anyone can edit to wikipedia. With somethings that you search on wikipedia may not always be true as it can be edited with false information. I think that wikipedia should not always be trusted but it does give good information if it is not false.
I think that flickr is useful for people who have family or friends overseas, because you can share photos online and communticate with others. With your photos flickr lets you edit them online.
Delicious is a online bookmarking service.

Cool things for blogs!

On your blog you can do more than just writing. You can do other things such as adding a photo or video to what your blog is about. For example this picture here.

Email

CC is Carbon Copy. Carbon copy is when you are sending an email that you send to more than one recipient. Once you have sent it that people who recieve the email can see what other recipients you have sent the email too. You would use this when you are sending a forward email to more then one person or you want to get something through to more than just one or two people. BCC does the same thing. BCC stands for (Blind Carbon Copy). The only thing it does differently is hide the other recipients from showing up so others can not view the other recipients.

I think blogs are interesting and it's a fun thing to do. It's just like your diary/journal entry but online so other bloggers can view your blog and comment what they think of it. It's not the type of thing I would do myself. I wouldn't like to blog about stuff that's happenend or happening in my life like other people do. I think posting personal stuff over the internet is inapropriate.
