Edutainment Multimedia materials with a combination of educational and Multimedia A combination of text with sound, video, animation, and graphics Expert system Software that enables computers to think' like experts Telecommute Use computers to stay in touch with the office while working at Information superhighway Internet system designed to provide free, interactive access to vast resources for people all over the world What tool is often used in data mining? Artificial Intelligence What Al method is used for the following processes? Divide data into groups based on similar features or limited data ranges. Data mining is simply filtering through large amounts of raw data for useful The most popular tool used when mining is artificial intelligence (AI). Al technologies try to work the way the human brain works, by making intelligent guesses, learning When are clusters used in data mining? When data isn't labelled ni a way What types of data storage can be used in data mining? All types of data storage What can an analyst do to improve the data mining results? Refine the parameters Use other data analysis tools to examine the data Data warehouse Storage method of archiving large amounts of data to make it Cleansed data Data free from duplicate and erroneous information Data mining A process of filtering through large amounts of raw data for useful information In data mining, patterns found while analysing data are used for further Data mining is used to detect false insurance claims Large amounts of data stored in data warehouses are often used for data mining... The data is first cleansed... to remove....duplicate... information and errors. The data is then analysed using a tool such as artificial intelligence What does a CCD contain? Thousands of photo-transistors - one for each What is a pixel? Akind of dot which makes up a picture. It's short for picture How can you view pictures before they are downloaded to a PC? On the LCD. When you have downloaded the images, what can you do with them Retouch them, manipulate them or print them out. Is special software required? Yes, but it comes with the camera. Why is the resolution important? The higher the resolution, the more details you'l be able ot get ni the picture; the better the picture quality. What does the capacity of a digital camera depend on? Memory size. Why is it worth getting a rechargeable battery? Because the cameras can use a lot of power so batteries need to be replaced often. You can write to hard disks faster than optical disks. Floppy disks have a lower capacity than other devices. CD-ROMs and floppy disks are both low priced. DVD-RAM has a higher capacity than other optical disks. CD-ROMs cannot be re-recorded but some other optical disks can be..‫ضغوطة والكتابة إليها‬0‫قراص ا‬4‫ يمكنك القراءة من أقراص محركات ا‬،‫قراص الثابتة‬4‫مثل ا‬ Like hard disks, you can read from and write to CD-MO drives.
