Android

An android is an artificially created being that resembles a human being. The word derives from Greek Andr- ‘man, human’ and the suffix -eides used to mean ‘of the species, kind, alike’ (from eidos ‘species’).

The word droid, a robot in the Star Wars universe, is derived from this meaning. Some people maintain that, etymologically, the word android means resembling a male human and that a robot resembling a woman should logically be called a gynoid for sexist language to be avoided; however, this word is not commonly used.

Unlike the terms robot (a mechanical being) and cyborg (a being that is partly organic and partly mechanical), the word android has been used in literature and other media to denote several different kinds of man-made, autonomous creations:

a robot that closely resembles a human

a cyborg that closely resembles a human

an artificially created, yet primarily organic, being that closely resembles a human

Although essentially human morphology is not the ideal form for working robots, the fascination in developing robots that can mimic it can be found historically in the assimilation of two concepts: simulacra (devices that exhibit likeness) and automata (devices that have independence).

The term android was first used by the French author Mathias Villiers de l'Isle-Adam (1838-1889) in his work Tomorrow’s Eve, featuring a man-made human-like robot named Hadaly. As said by the officer in the story, “In this age of Realien advancement, who knows what goes on in the mind of those responsible for these mechanical dolls.”

Computer Basics

To accomplish a task using a computer, you need a combination of hardware, software, and input.

Hardware consists of devices, like the computer itself, the monitor, keyboard, printer, mouse and speakers. Inside your computer there are more bits of hardware, including the motherboard, where you would find the main processing chips that make up the central processing unit (CPU). The hardware processes the commands it receives from the software, and performs tasks or calculations.

Software is the name given to the programs that you install on the computer to perform certain types of activities. There is operating system software, such as the Apple OS for a Macintosh, or Windows 95 or Windows 98 for a PC. There is also application software, like the games we play or the tools we use to compose letters or do math problems.

You provide the input. When you type a command or click on an icon, you are telling the computer what to do. That is called input.

How They Work Together

First, you provide input when you turn on the computer. Then the system software tells the CPU to start up certain programs and to turn on some hardware devices so that they are ready for more input from you. This whole process is called booting up.

The next step happens when you choose a program you want to use. You click on the icon or enter a command to start the program. Let’s use the example of an Internet browser. Once the program has started, it is ready for your instructions. You either enter an address (called a URL, which stands for Uniform Resource Locator), or click on an address you’ve saved already. In either case, the computer now knows what you want it to do. The browser software then goes out to find that address, starting up other hardware devices, such as a modem, when it needs them. If it is able to find the correct address, the browser will then tell your computer to send the information from the web page over the phone wire or cable to your computer. Eventually, you see the web site you were looking for.

If you decide you want to print the page, you click on the printer icon. Again, you have provided input to tell the computer what to do. The browser software determines whether you have a printer attached to your computer, and whether it is turned on. It may remind you to turn on the printer, then send the information about the web page from your computer over the cable to the printer, where it is printed out.

II. Television

Old portable television

A television (also TV or telly) is a device (tool) with a screen that receives broadcast signals and turns them into pictures and sound. The word “television” comes from the words tele (Greek for far away) and vision (seeing).

Usually a TV looks like a box. Older TVs had large wooden frames and sat on the floor like furniture. Newer TVs became smaller so they could fit on shelves, or even portable so you could take it with you wherever you went. The smallest TVs can fit in your hand. The largest TVs can take up a whole wall in your house, and may sit on the floor, or be just a large flat screen that can be mounted on the wall. Many TVs are now made in wide screen shape like movie theatre screens, rather than old, more square TVs.

A television has an antenna (or aerial), or it has a cable. This gets the signal from the air, or cable provider. TVs can also show movies from DVD players or VCRs. TVs can be connected to computers and game consoles, usually through a kind of socket called “SCART”.

III. Web or World Wide Web

The World Wide Web is the part of the Internet that contains web sites and web pages.

It is not used to describe WebPages that are used offline where net services are not available, or no computer network exists - such as Wikipedia on CD. In this case no real physical site exists other than the place where the computer is. Blog and Wiki capabilities will also not be available because these require a communication with other computers.

IV. Radio

Radio is a communications invention. Though originally used to communicate between two people, it is now used to listen to music, news, and people talking. Radio shows were the predecessor to TV programs.

V. DVD

DVD most commonly stands for “digital versatile disk”. It can play video that is of a higher quality than a VHS tape.

VI. Two kinds of DVD

They can also hold 4.7 GB of information as opposed to the 700 MB that a CD can hold. A plus of using a DVD for a video is the ability to have interactive menus and bonus features such as deleted scenes and commentaries.

VII. Email

Email (electronic mail) is a message, usually text, sent from one Internet user to another. Email is quicker than snail mail(mail) when sending over long distances and is usually free. To send or receive an email, a computer with a modem and telephone line connected to the Internet, and an email program are required. Email addresses are generally formated like this: login@server.(com or fr or org or uk or other).

Some companies let you send and receive email for free from a website. Gmail, Hotmail and Yahoo! do this.

VIII. Human

Here are two humans.

A man is on the left and a woman is on the right. A human or human being is a person, like you. A male human is a man, a female human is a woman. If you think about all humans in the whole world, they are called humanity. In the past, people have also used man and mankind to mean all humans.

Humans are called Homo sapiens by scientists. Humans are an animal species that belongs to the group called primates. Monkeys are primates too, but the primates most like people are gorillas and chimpanzees. Most scientists think that chimpanzees and humans came from a common ancestor by what is called evolution. Other animals even more like humans than chimpanzees once lived too, but they are now extinct.

Human rights are those things that everyone deserves and the way they should be treated by other people.
