On-line discussion forums
A discussion forum is a section of a website where anybody can insert there views or comments on the particular subject. Normally you need to register to insert a comment onto a forum, and logon. There are many ways how forums work, one way would be filling in a form and then adding a comment (this is a sought of e-mail), and the other way would be just adding a Name and then a comment (this goes directly onto the website and doesn’t use e-mail). Forums are used a lot these days and they are becoming popular because you can read peoples opinions of certain subjects all around the world. A popular forum subject these days are about University. Forums can be used for helping people and getting information. Forums are useful as well as the information is always on there so people can always post their comments. It is a great way of communicating across the world and to see what other people think of the different subjects.
How does a forum work
First off somebody must start a forum. For example a forum I go on is www. Tutorial forums. com. This helps people with tutorials and gives people resources and information. Somebody can enter a thread on any subject they want (reverent to the forum). So say I wanted know how to use a certain program or something I can post the tread and then people can post a comment on the specific subject.
Lobby Groups
Lobby groups is where a group of people gather and discus something that they would like to be changed.
For example the Monday Lobby Group is a weekly meeting of peace and security organizations in Washington, D.C. The group discusses the upcoming Congressional committee meetings, hearings, and votes, on issues relating to arms control and international security. Various lobbying plans are discussed (for groups with a lobbying component) and related tasks are divided among the participating groups.
Information Services
Information services are services that provide information, I will be looking it how these information services provide information to the community. Information services are a wide range and can include museums, libraries and local authorities.
Libraries
Libraries are a big source of information for the general public and open to everyone to find information. The latest libraries use ICT to sought out the books coming in and out the libraries. The Luton library uses the most sophisticated ICT to seek out the books coming in and out, and is very effective.
Museum
People can use museums to find out information.
GPS on pursuit
The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. Department of Defence. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day. There are no subscription fees or setup charges to use GPS. GPS is used for boats and can locate any object with the GPS system on (i.e. boats, cars, planes). The satellite can tract where the device is quickly as the satellites travel 7000mph travelling the world twice a day.
How it works
GPS satellites circle the earth twice a day in a very precise orbit and transmit signal information to earth. GPS receivers take this information and use triangulation to calculate the user's exact location. Essentially, the GPS receiver compares the time a signal was transmitted by a satellite with the time it was received. The time difference tells the GPS receiver how far away the satellite is. Now, with distance measurements from a few more satellites, the receiver can determine the user's position and display it on the unit's electronic map.
The satellite system
The 24 satellites that make up the GPS space segment are orbiting the earth about 12,000 miles above us. They are constantly moving, making two complete orbits in less than 24 hours. These satellites are travelling at speeds of roughly 7,000 miles an hour. GPS satellites are powered by solar energy. They have backup batteries onboard to keep them running in the event of a solar eclipse, when there's no solar power. Small rocket boosters on each satellite keep them flying in the correct path.
