Disscusions fourms and blogs

Blogs tend to be more personal as people are expressing the views on subjects more openingly as the people who would be looking at there blogs will tend to have the same views so will be more open in their comments.

whereas fourms have a whole range of people with different views alot fourms tend to get into heated debates about peoples views on subjects

group project week2

with the footage we got from week one we decided to split into two groups with alex and nick editing the video while me and ace worked on the website with him focusing more on the photoshop side and me on the flash.
We have the college title and logo down and the basic start of the website but we still have alot more to do.

although our group is starting to struggle with nick who seems to be off all the time, and now stopping progress as he took the video tape home last week and the editing was done on his account video progress has halted.

Group Project - week 1

We started off planning our interview questions which we agreed should be simple and quick to answer questions so as to not leave long blank pauses in the interview where people would be thinking about their answers.
the next day we booked out a camera and got a few shots around college, we also got 2 interviews with staff of the college but failed to retrieve one with a student as everyone we asked seemed to be unwilling.

wireless application protocol and global system for mobiles.

WAP (Wireless Application Protocol) is an open international standard for application-layer network communications in a wireless-communication environment. Most use of WAP involves accessing the mobile web from a mobile phone, it was first released in 1999 with mixed reviews across the world with it being a huge succsess japan however failing to impress uk citizens until 2003/04 where it sparked some intrest in the uk, WAP however has died out with phones providing HTML instead.

GSM(Global System for Mobiles) is a second generation digital mobile cellular technology using a combination of frequency division multiple access (FDMA) and time division multiple access (TDMA). GSM operates in several frequency bands: 400MHz, 900MHz and 1800MHz. On the TDMA side, there are eight timeslots or channels carrying calls, which operate on the same frequency. The standard was jointly developed between European administrations under Groupe Speciale Mobile in the 1980s and introduced commercially in 1991. Unlike other cellular systems, GSM provides a high degree of security by using subscriber identity module (SIM) cards and GSM encryption.

The Moodle Disscusion fourm

Personally i believe the disscusion fourm is a very good idea to help the class to digitally communicate although i doubt it will be kept serious for too long as everyone has already started to mess about on it.
