• The following is a sampler from an article by Robert Harris, ”TRUTH OF THE INFORMATION AGE.”
• 1)Information must compete. A need exists for information to stand out and be recognized in the increasing clutter, the data smog, that surrounds us.

  2)Newer is equated with truer. We have lost the sense that any fact or value can endure.

  3)Selection is a viewpoint. If you want to receive a more-balanced view of reality, choose multiple sources for your information.
• 4)The media sell what the culture buys. In other words, information is shaped by cultural priorities.

  5)The early word gets the perm. The first media outlet to cover an issue often defines the terms, context, and attitudes surrounding it.

  6) You are what you eat and so is your brain. If certain ideas are never presented to you, you cannot draw adequate conclusions.

  7) You are what you eat and so is your brain. If certain ideas are never presented to you, you cannot draw adequate conclusions.
• 8) Ideas are seen as controversial. It is probably impossible to make any assertion that will not find some supporters and some detractors.

  9) Undead information walks ever on. Lies, hoaxes, misinformation, rumours, disinformation, and garbled truth never really pass away. They continue to circulate.

  10) Media presence creates the story. When the media are present, especially film news or television media, people behave much differently from the way they would if not being filmed.
• 11) The medium selects the message. Television is mostly pictorial, partly aural, and very little textual, so visual stories are emphasized: fires, chases, disasters.

  12) The whole truth is a pursuit. The information we receive comes to us filtered, selected, slanted, verbally charged, and sometimes fabricated. What is left out is often even more important than what is included.
• A computer is an electronic device that stores and processes data (information). It runs on a program that contains the exact, step by step directions to solve a problem
• TYPES OF COMPUTER

  1)Personal Computers

  2) Desktop Computers

  3) Laptops

  4) Personal Digital Assistants (PDAs)

  5) Server

  6) Mainframes

  7) Wearable Computers
• It is a single-user instrument. PCs were first known as microcomputers since they were a complete computer but built on a smaller scale than the enormous systems operated by most business.


  Personal Computer
• A PC that is not designed for portability is a desktop. The assumption with a desktop is that it will be set up in a permanent spot. A workstation is simply a desktop computer that has a more powerful processor, additional memory, and enhanced capabilities for performing a special group of tasks, such as 3D graphics or game development. Most desktops offer more storage, power, and versatility than their portable counterparts.


  Desktop Computer
• Commonly called notebooks, are portables that integrate the essentials of a desktop in a battery-powered package somewhat larger than a typical hardcover book.


  Laptops
• They are tightly integrated computers that usually do not have keyboards but rely on a touchscreen for user input. PDAs are typically smaller than a paperback, light-weight, and battery powered.

  •Personal Digital Assistants (PDAs)
•  It refers to a computer that has been improved to provide network services to other computers. It usually boast powerful processors, tons of memory, and large hard drives.


  Server
• In the early days of computing, mainframes could fill an entire room or even a floor of rooms. As computers have grown smaller and power has increased, the term mainframe has largely been replaced by enterprise server. The former term is still used, especially by large firms, to describe the huge machines that process millions of transactions every day, hour, minute, or second. This type of computer typically costs millions of dollars. Although some supercomputers are single computer systems, most comprise multiple, high-performance, parallel computers working as a single system.


  Mainframes
• They are integrated into cell phones, watches, and other small objects or places. They perform such common computer applications as databases, e-mail, multimedia, and schedulers.

  Wearable Computers
• Several historian trace the origin of the Internet to Claude E. Shannon, an American Mathematician who was considered as the “Father of Information Theory”. He worked at Bell Laboratories and at age 32, he published a paper proposing that information can be quantitatively encoded as a sequence of ones and zeroes.
