CAM - Computer Aided Manufacture

What is CAD?
CAD is software that is used by design engineers. This new process allows designers to have a whole new aspect on designing products. The software allows the user to do either 2D/3D shapes that can then be labelled and drawn to scale but in a computer.

How does CAD work?
The way in which CAD works is that the designer/developer can purchase some software such as Coral Draw or Google Sketch-up. The software program then will allow the user to create digital drawings that can be either printed out or even be send via emails to other people.

What is CAM?

CAM is an technology that uses computer software and machinery to automate a particular process. An example of a CAM process would be robots that are producing cars on a large scale. This CAM process relies on the CAD side as well this is because the machines needs some form of an instruction on what is wanted.

A podcast is a series of video or audio files that a user can download and listen to which is often provided as a subscription so the episodes are automatically downloaded to the user's device. The user uses client application software which is known as a podcatcher which accesses the server to check for updates so it can download it for the user to listen to the file when they are not connected to the internet. There are many applications that allow users to subscribe and listen to podcasts by streaming them or by downloading them.

A Vlog the shortened word for a video blog or a video log. It is a type of blog in which the video is a form of web television. Vlog entries are often a combined embedded video with supporting text and images. The Vlogs are usually recorded in one take or they are cut into multiple parts.  The Vlog category is a popular category on YouTube. Some bloggers have used “Vlog” for years, however “vlogging” has recently become more common as equipment for the footage of the logs have become cheaper recently.                                            There are two different types of Vlogs.

Personal Vlogs

Personal Vlogs are an online video which records one person delivering information that they intend to deliver to their audience.

Live broadcasting vlogs

In 2008, YouTube announced a live broadcasting feature called “YouTube Live”. Over time this feature has been introduced to other social platforms such as Instagram and Facebook.

How it works

To create a Vlog, bloggers use a camera and a microphone to record themselves. Sometimes they will record everything in one sitting, however some bloggers create their Vlogs in multiple different parts. After they have their footage, they then go onto editing the footage on their computer, before putting it online.

What is the Global Positioning System? by Cody

# data[].attributes.body
The Global Positioning System is more commonly referred to as GPS. It is a satellite navigation system that is owned by the United States government and is ran by the United States Air Force. It is a global navigation satellite system that provides location and time information to a GPS receiver anywhere on Earth. These receivers receive satellite signals passively, they don't transmit and they require an unobstructed view of the sky so they can only be used effectively outdoors. A GPS receiver estimates the location of the satellites because that information is included in the transmitted Ephemeris data (data that tells the GPS receiver where each GPS satellite should be at any time throughout the day). By estimating how far away a satellite is, the receiver also knows it is located somewhere on an imaginary sphere centred at the satellite. It then determines the sizes of several spheres, one for each satellite, and therefore knows the receiver is located where these spheres intersect.

Uses artificial intelligence technologies to simulate the behaviour of a business to help solve problems systematically without the need for a person to handle them. They contain large amounts of information about how the business operates and therefore, how they should work. It allows a computer, or system with this knowledge to make important business decisions. They are very complex and can be efficient as they reduce the need for human expertise. They contain a set of rules and prior knowledge which they use to perform tasks.

Regulation of Greenhouse Temperature Monitoring Software - Adam Parker.

# data[].attributes.body
It is software that is directly aimed at maintaining and sufficiently altering the temperature of a Greenhouse. This is essential so that the plants do not die.

A mechanical part involved in this process could be a Thermostat which is activated at a specific temperature, once this condition has been met a switch will be flicked. The condition of the switch state will result in a certain value being produced, it is either on or off (on being 1, and off being 0).

Once this value is sent to other devices it will cause events to occur such as sprinklers to come on or windows to be opened.

- This is a technology that's used in order to verify the legitimacy or originality of paper documents. It has special ink which is sensitive to magnetic fields, is used in the printing of certain characters on the original document, information can be encoded in the magnetic characters.
How it Works:

Each check is printed with a series of characters on the bottom of the document. The characters are printed using a special kind of ink which has additional magnetic resonance allowing it to absorb and emit a magnetical signal. When the ink goes across the scan path the magnetic ink passes a magnet in the scanner to the ink before it passes the scanner. The MICR read head is a device that is built into the scanner designed to read the magnetic signal emitted by the ink passing over it.

Web Browsers
What is a web browser?
A web browser is a software application which is used to retrieve information using the World Wide Web. The client runs the web browser on the computer, where the computer contacts the Web server and requests information which is displayed for the client. The web serve sends the information back to the browser which displays the results on the computer.
How does a web browser work?
Web browsers consist of client software that runs on your computer and displays home pages on the Web . The browser has to find a IP address of the web server. After finding the IP address the browser sends an HTTP request to the server requesting the appropriate file. After getting the requested file, the browser has to interpret and change the HTML page. Then it can display that web page to the user.

What is ANPR?

Automatic Number Plate Recognition (ANPR) technology is used to help detect, deter and disrupt criminality at a local, force, regional and national level, including tackling travelling criminals, Organised Crime Group (OCG) and terrorists. ANPR provides lines of enquiry and evidence in the investigation of crime and is used by law enforcements agencies.

How it works?

As a vehicle passes an ANPR camera, its registration number is read and instantly checked against database records of vehicles of interest. Police officer can intercept and stop a vehicle, check it for evidence and, where necessary, make arrests. A record for all vehicles passing by a camera is stored, including those for vehicles that are not known to be interest at the time of the read that may in appropriate circumstances be accessed for investigate purposes. The use of ANPR in this way has proved to be important in the detection of many offences, including location stolen vehicles, tackling uninsured vehicle use and solving cases of terrorism, major and organised crime. It also allows officers' attention to be drawn to offending vehicles whilst allowing law abiding drivers to go about their business unhindered.

What is a barcode?
A barcode is a code made from numbers and a pattern of parallel lines of different widths.

How does it  work?
A laser light is shone at the barcode. The light is reflected back off the barcode into a CCD. The white areas reflect more light and the black areas reflect less light. The CCD measures the amount of reflected light and the light reflected is then converted into an electrical charge where it is then converted to a binary code. The binary code is transmitted to the till computer. The values are often sent as ascii code.
