Finally... An Understandable Introduction To Computers

Written by Roger A. Pendey

When you mentionrepparttar word "technology," most people think about computers. Virtually every facet of our lives has some computerized component. The appliances in our homes have microprocessors built into them, as do our televisions. Even our cars have a computer. However,repparttar 144989 computer that everyone thinks of first is typicallyrepparttar 144990 personal computer, or PC.

It is a general-purpose tool, built around a microprocessor. A PC has many different parts such as memories, a hard disk, a modem, etc that work together. A PC is said to be "general purpose" because you can do many different things with it like: you can use it to type documents, send e-mail, browserepparttar 144991 Web and play games.

Let us look atrepparttar 144992 main components of a typical desktop computer.

Central processing unit (CPU): The microprocessor "brain" ofrepparttar 144993 computer system is referred to asrepparttar 144994 central processing unit. The CPU oversees everything that a computer does.

Memory: This fast storage area is for storing data and is connected directly torepparttar 144995 microprocessor. That's why it is fast. There are various types of memory in a computer system:

Random-access memory (RAM): Used to temporarily store information thatrepparttar 144996 computer is currently working with.

Read-only memory (ROM): It refers to computer memory chips, containing permanent or semi-permanent data that does not change.

Basic Input/Output: Required to establishrepparttar 144997 basic communication whenrepparttar 144998 system is turned on. It is directly connected torepparttar 144999 motherboard.

Artificial Intelligence

Written by Daniel Punch

Science fiction has built uprepparttar idea of artificial intelligence for years. Giving machines intelligence often spellsrepparttar 144882 end of mankind as they then rise up against their creators and violently free themselves from oppression. There are cautionary tales such as inrepparttar 144883 film "Spider Man 2" in whichrepparttar 144884 robotic arms of Dr. Octavius start controlling his brain thus forcing him to perform actions of benefit to them. I've never really had an interest in artificial intelligence until recently when I started studyingrepparttar 144885 very basics at university. The only AI Science Fiction that's ever actually interested me was 'Blade Runner' and its novel, 'Do Androids Dream of Electric Sheep?' written by Philip K. Dick. The subtext ofrepparttar 144886 story deals with AI becoming self-aware but still unaware of its true nature, a concept that interested me greatly. Real AI is quite fascinating and in many ways entirely different to what I expected.

To start with, what exactly is AI? defines it as follows: 1. The ability of a computer or other machine to perform those activities that are normally thought to require intelligence. 2. The branch of computer science concerned withrepparttar 144887 development of machines having this ability. If you take a look at this you may notice thatrepparttar 144888 field of AI is actually far broader than many people give it credit for. Evenrepparttar 144889 Google search engine can be said to incorporate some ofrepparttar 144890 research done in AI. The definition of AI and intelligence itself sometimes varies but it's probably safe to say that a simple explanation is that if a machine exhibits a measure of intelligence in some area it can be called AI. The AI of movies is usually entirely self aware, emotive, and for all intents and purposes 'alive'. It is capable of learning, reasoning, explaining and deceiving. The AI I've experienced (and this is very basic, scratching onlyrepparttar 144891 surface ofrepparttar 144892 depth of studies into AI) is far more specialized, focusing on just one aspect of a problem that could potentially be much larger. There are various areas of research being carried out into creatingrepparttar 144893 humanoid machines of science fiction, but as yet most are still restricted torepparttar 144894 realms ofrepparttar 144895 imagination. One very impressive piece of technology isrepparttar 144896 Honda ASIMO project. This project has created a humanoid robot with some remarkable features. I'm not entirely sure if there's really a practical use for this (I think they're just trying to justify their funding withrepparttar 144897 applications mentioned onrepparttar 144898 website) but it scores points for being one ofrepparttar 144899 coolest uses of technology I've ever seen. You can see some videos of ASIMO in action here:

From what I can tell ASIMO isn't intended to be a particularly human robot beyond superficial levels. He doesn't exhibit emotion or learn outside of his constraints (he can learn areas and navigate them etc. but you couldn't just sit down and teach him to playrepparttar 144900 piano without getting in and doing some serious reprogramming). He's not going to be fooling anyone into believing that he's human any time soon.
