  1. 1. vs. hard disk:
  2. 3. extra copy of a document, file or programBinary means "two," or "base two." The binary system is a way of counting using just the two numbers 0 and 1.bit is an electronic signal which is either on (1) or off (0). It is the smallest unit of information the computer uses.A browser is a software program that lets you explore the World Wide Web to find text, graphics, sound, movies, games, chats and more: A byte is a group of 8 bits, strung togetherA cable is a long, rubber-coated bundle of wires, with plugs on either end, that connects computer partsA round, shiny portable disk that stores large amounts of software and informationA cell is the "box" where a column and a row intersect, in a spreadsheetChat is a way people in different places can "talk" to each other by typing their words into a computerA chip is a tiny piece of silicon with electronic circuits. The chip is the most important part of the computerA computer is an electronic machine that) takes in data and instructions (input)
  3. 4. A network is a number of computers connected together to share information and hardware
  4. 5. A pixel is a tiny dot of light on the monitor
  5. 6. A monitor is the TV-like part of the computer that you look at to see information
  6. 11. Storage
  7. 12. Hard Disk (Hard Drive)
  8. 13. little like your real desktop - has only your current work on it (which could be ruined by a spill of Coke or coffee!) Like a file cabinet - has long-term storage of work (it's safe from spills!)
  9. 15. A spreadsheet is a document which helps you organize data in rows and columns of cells
  10. 17. amount
  11. 22. Software is the programs that run on a computer
  12. 23. you want to use a program, a temporary copy is put into RAM and that's the copy you use Holds the original copy of the program permanently
  13. 24. are stored electronically in bits on the chip, in electronic offs and ons (0's and 1's), so RAM needs electrical power to hold the contents Contents are stored magnetically, also in bits which are off or on (0 or 1), so the Hard Disk does not need power to hold the contents
Down
  1. 1. RAM, also called memory, is temporary storage space on chips in your computer. RAM stands for Random Access Memory
  2. 2. wide web (or web): A virus is a computer program that was written to purposely damage computer systems
  3. 4. The processor is the chip which is the brains of the computer. It is also know as the CPU (Central Processing Unit).
  4. 6. puts out information (output)
  5. 7. storage of files and programs Permanent storage of files and programs
  6. 8. A device that "takes a picture" of something and turns it into a computerized image
  7. 9. In a database, a record holds all the information about one item or subject. It is like one index card in an index card file.
  8. 10. A hardware device that is connected to a computer, usually by a cable
  9. 14. url: A URL is the address of a website on the World Wide Web.
  10. 16. works with the data (processing)
  11. 18. A virus is a computer program that was written to purposely damage computer systems
  12. 19. of chips (microprocessors) Consists of hard disks (platters)
  13. 20. 500MB to 300 GB)
  14. 21. file you are modifying, plus all the changes you make, are kept here in RAM until you do a "save" When working on a file, the original file is left untouched here in the Hard Drive until you do a "save;" the "save" copies the new version of the file that's in RAM onto the Hard Disk (and usually replaces the original file)
