Personal computer
* Any personal computer printing press.
* Many personal computers use a second processor to perform floating-point mathematical operations.
* Most personal computers come without a network adapter installed because there are so many choices
  - connect to a network with the use of a voice system
* Most personal computers have both a parallel port and at least one serial port
  - internal modems and thus are ready for Internet connectivity
  - use magnetic disks to store information permanently
* Some personal computers come with built-in screenreaders.
* are a commodity
  - at present the weak link in Internet security
  - complicated, but television medium many people understand
  - currently air-cooled by either free or forced convection
  - digital computers
  - for a single user
  - located in desks
  - low in price and easier to use
  - low-cost, typewriter size computers
  - notorious for having a half-life of about two years
* are now an essential part of the working environment
  - integral part of education on all levels
  - capable of processing large amounts of information at very high speeds
  - widespread in Poland, acquired both legally and by smuggling
  - possible because of the invention of the chip
  - so commonplace they are akin to furniture
  - still in the embryonic stage
  - ubiquitous
  - very susceptible to damage during power failures and power surges
* are, depending on age and equipment, hybrids of terminals and workstations.
* collect and store data in digital format from all GCs and HPLCs.
* demand personal responsibility for information technology management.
* have an internal clock that is year sensitive
  - various types of ports
* provide a good way for people to escape their physical confines.
* recognize text and speech.
* suffer from a four-point gap between service and product quality.
* used for businesses generally originate from four sources today.

Workstation
* are artifacts
  - computers that are bigger than micros and have the power of mainframes
* are more powerful versions of personal computers
  - than just computers
  - single-user computer systems
* computer client that can access data and program in the server computer.
* minicomputer or mainframe computer that is small enough to fit on a desktop.

Faster computer
* allow more sophisticated algorithms to discover patterns in large datasets.
* speed the processing and display of incoming Web pages.

Home computer
* All home computers are microcomputers.
* are computers.
* help to find a cure for disease.
* utilize commercial software to interact with modems.

Human brain
* Most human brains have energy.
* are body parts
  - larger and more complex than most mammals and all other living primates
  - the most prominent medium in which memes live
* can pose problems at both the beginning and the ending of life
  - quickly adjust to different color temperatures
  - reconstruct some of the information that is lost in packets
* continue to quickly grow during the first two years of life.
* have a wider variance
  - components for communicating with one another using language
  - trouble
* is an important part of the human body
  - highly complex, non-linear, parallal and efficient information processing system
  - the most important of all the organs of the body
* like to describe themselves as the most complex objects in the known universe.
* seem ready-made to process language.
* serve a function which can be performed equally well by other mechanical systems.
* weight two percent of our total weight.
