+ Biometrics: Biology :: Computer science :: Authentication methods
  * Many computers have a fingerprint scanner. This allows for some security.
  * All computers use binary at the lowest level. Most computer storage, like compact discs and DVDs, use binary to represent large files.
+ Computer engineering: Computer science
  * Computers are electrical machines that run programs. In Computer engineering classes, students learn about the hardware and software of computers. This is the electrical part. They also learn how to program the ROM or Flash memory so the computer can do something useful
  * Computers can be part of several different networks. Networks can also be parts of bigger networks. The 'local area network' in a small business is usually connected to the 'corporate network' of the larger company. Any connected machine at any level of the organization may be able to access the 'Internet', for example to demonstrate computers in the store, display its catalogue through a web server, or convert received orders into shipping instructions
  - numbering formats: computer science
  * Computer numbering formats' are the ways that computers and calculators represent numbers. Most computers use a system of binary which is composed of ones and zeros
+ Computer, Computers and waste: Tools
  * Computers can become obsolete quickly, depending on what programs the user runs. Very often, they are thrown away within two or three years, because newer programs require a more powerful computer. This makes the problem worse, so computer recycling happens a lot. Many projects try to send working computers to developing nations so they can be re-used and will not become waste as quickly, as most people do not need to run new programs. Some computer parts, such as hard drives, can break easily. When these parts end up in the landfill, they can put poisonous chemicals like lead into the ground water
  - Main hardware
+ Digital media: Media
+ Division by two, Binary, Computers
  * Computers use the binary number system to store information. Information is broken up into tiny pieces called 'bits'. Each bit is either a 0 or a 1. Replacing regular division with bit shifts is a way to do program optimization.
+ Internet Protocol, IP address: Internet protocols
  * Some computers have the same IP address for a very long time. Some computers change their IP from time to time.
  * This would pick up shows from broadcast television stations. A TV station could be many miles away, and still be picked up. TVs can also show movies from VCD and DVD players or VCRs. Cable TV and Satellite television can provide more programs at once than broadcast can. Video game consoles connect to most modern TVs. Some computers can also use a TV as a monitor.
+ Random, Making random numbers: Mathematics :: Cryptography
  * Computers can make what appear to be random numbers. There are two ways to make them.
+ Telephone, Types of telephones
  * Computers can use a machine called a modem to talk to other computers over a telephone line. This allows a computer to connect to other computer networks including the Internet.
+ Typesetting, Digital era: Typography :: Typesetting
  * Computers excel at automatically typesetting documents.
+ USB flash drive, Good points and bad points, Pros: Storage devices
  * Most modern operating systems can use a flash drive, without the need to install special software. To most operating systems, the flash drive looks like a hard drive. The operating system can use any file system. Some computers can start from a flash drive.
+ Video camera, Uses: Cameras :: Electronics :: Data input
  * Special uses of video cameras include systems that capture images at the finish line to time races and sporting events. Some toll roads use video cameras to make pictures of the license plate of any car that fails to pay tolls. Computers then identify the drivers and mail enforcement letters to collect the missed tolls
  * Many computers have a basic video and graphics capabilities built-in to the computer's motherboard. They are fast enough for basic computer use and even some basic computer games. If a computer user wants faster and more detailed graphics, a video card can be installed
+ Virtual memory
  * Computers run software. This software will need computer memory to run, and do what it needs to do. Most computers in use today can do more than one thing at a time, they run more than one application. This is known as multiprocessing.
