Why you might not want to build your own PC?
Well there is lazy or plain ole don't have a clue whats in the box , or you like all of the useless crapware that a new preloaded computer has loaded in it (just kidding) . If you have no idea where to start ask a few geeks or anyone who has worked on a system like installing Ram ,hard drives , bigger heat sinks etc . they are usually wanting to show off there knowledge . Pretty much all of the connectors from the power supply need to be hooked up to anywhere there is a mating plug motherboard drives etc everything requires power ; memory has a notch in it so it goes in only one direction , get what speed the motherboard specs say 2 gigs for XP 4 gigs for Vista. video card ? are you a gamer then one of the more high performance cards that you can afford , just read mail? get a cheaper (more cost effective)video card. Power supply? go to eXtreme PSU Calculator and input your needs ,# of hard drives etc amount of ram number of fans etc also try to buy a 80+efficient model if the computer is to run for than a couple of hours a day the energy savings will pay for its self ,, hard drives are cheap try to get the most ram on the size drive as you can it helps to NOT fragment the info being put onto the drive. My favorite box (or case) for a high performance q6600 or e6600 Intel is an Antec 900 for the price it is fantastic . the next thing you know you are an expert!! and you will wonder why you never did this before! then you will start looking at Overclocking..... but that is another story!
Who invented machine language?
Computer languages were not discovered, as no computers used them before people used them. Computer languages are artificial languages invented by people to simplify control of computers.
As to the inventors of the earliest computer languages they were:
Both did their original compiler development work ca. 1954.
Wintel is windows running on Intel or x86 architecture
It's short for Windows + Intel
Why you save computer files with extension name?
Extension names allow your computer to recognize which program is needed to open the file.
How is data converted into signal?
Analog electrical signals are converted into digital signals by an analog to digital converter (ADC). A ramp is compared to a signal and comparator will send data bits to represent the signal value in digital value compared to a reference internal voltage.
As you may or may not know, a bit has two values, 1 and 0. They represent a current going through a circuit. If the current is running, the value is 1. Otherwise, it is 0. Simple logic. Then there is Binary language, the very primitive way of how the computer communicates. It sends information in 1s and 0s, which then get interpreted. Of course, programming languages can't get pushed through the computer in the words that we see, so the computer must convert it into it's binary language.
Bits do not have values at all. They do however have states, for example, 1= true and
0=false. It cetainly does not represent current going, flowing or otherwise trough a circuit. It is however represent a binary state meaning two states . A COMPUTER DOES NOT CONVERT THIS STATES INTO BINARY LANGUAGE. However this is the language that all machines [COMPUTERS] understand; "1" and "0". Live and learn but do not pass along bad information please.
What is a trap in an operating system with example?
Trapdoor is a secret undocumented entry point into a program used to grant access without normal methods of access authentication. A trap is a software interrupt, usually the result of an error condition.
Is a CDROM drive an input or output device?
A CDROM drive is neither an input device or an output device. A CDROM drive is a storage device.
there's no GigaBytes in MegaBytes, MB are in GB.... there's two schools of thought, the right one, and the lazy one... 1024 MB is 1 GB true.. on most storage you'll find they think it is 1000, so get the calculator out, divide your number by 1024, or 1000 if you want the lazy answer, also if you ever need to convert something, go to google and type in say something like "40534503 mb to gb" or "104 f to c" and it will do it for you
What are the components of an effective communication?
The Seven Components of the Communication Process
A source, presenter, or speaker who uters the message

A message, your words and ideas adapted to the audience
A channel, or means of distributing your words

How many people surf the web each day?
There are 1,630,625,048 users of the Internet in the world - a vast majority of these will utilise the World Wide Web service. This number was obtained from Worldometers (see related links), and will no doubt have changed by the time you read this, however...
An intranet is medium of communication in a closed community.Messages from the intranet is transfered through a gateway,with a firewall along with users authenticatedand encrypted messages, which cannot be viewed by any other person that does not belong to the virtual private network. It also used only in the local Area that means information shared in between two or more blocks required.
What do you need to do to use a command-line interface?
To get to the command line on your computer click on the Start button, click on Run, then type "cmd" in the run box. You will go to a black box called DOS. You will also see the command line prompt C:>, this is where you type in DOS commands. You can use DOS commands to do just about anything you can do in Windows except it's more work, you can copy, move, del files, etc. To get out of DOS just type Exit at the command prompt. You need to find yourself a book on DOS commands to know how to work it.
In broad terms the program that controls the various computer parts is called an Operating system. it uses an interface either command line or graphical to create a platform of interaction between the user and system
That stands for "personal area network". These networks tend to have a shorter range than a typical LAN.
What does tai mean in Japanese?

Difference between translated and interpreted computer languages?
The key difference between translation and interpretation lies within the choice of communication channel. Simply put, translation deals with written communication, while interpreting is all about the spoken word
Translators work on written documents, including books, essays, legal documents, medical records, websites, instruction manuals, subtitles for film or TV, or any other form of information in written form. Interpreters, on the other hand, are involved in projects that require live translation; for example conferences and business meetings, medical appointments and legal proceedings
Both translators and interpreters have a deep linguistic and cultural knowledge of their working languages, as well as the ability to communicate clearly and succinctly. It is, however, important to highlight the distinctive features of these two professions
Translators generally work from their home computers, and tend to specialize in a particular field. Good translators have excellent written skills and are usually perfectionists by nature, paying particular attention to the style of the source documents, as well as the accuracy and significance of the terms used within their translations
Unlike translators, interpreters do not provide a word-for-word translation; instead, they transpose spoken messages from one language into another, instantly and accurately. Interpreters work in real-time situations, in direct contact with both the speaker and the audience. They rely primarily on their linguistic expertise acquired through training and experience - a sentence in one language may be rendered an entirely different way in another. Good interpreters are endowed with very quick reflexes, as well as a good memory and speaking voice. An interpreter is often more than an on-demand translator, however - they also act as a facilitator between speaker and listener, both linguistically and diplomatically
How many bits of information that can be held in short term memory?
its simple and easy, one megabyte is equal to 1 million bytes so do the math bytes megabytes 1,000,000 = 1 10,000,000 = 10 100,000,000 = 100 250,000,000 = 250 and just check how many chips the memory have and do the math ...had to edit this answer substantially for inaccuracies, I think what he was trying to get at is divide the total DIMM memory by the number of chips on the module(ie: 256/8 = 32 megabytes per chip, or 32,000,000 bytes). Then to convert to bits you would need to multiply by 8 again (8 bits in a byte). Mind you this is for how much memory is on each chip and I don't think that is what this question is asking. I think http://wiki.answers.com/Q/How_many_bits_of_information_does_a_single_cell_of_a_memory_chip_on_a_256MB_PC2700_DDR_module_hold would be a more reliable answer.
