What are some advantages of the computer?
This is a loaded question with many potentially right answers. The potential advantages for using a computer depend closely on the intended use. Given a few potential uses, here are some of my thoughts:
For writing:
For organization
For programming
For research
Computers are not a panacea. There are many things for which a computer does not add significant advantages. But, used in an appropriate and realistic way, computers can enhance and facilitate certain activities.
To the poster of the question: What uses did you have in mind?
Spell Checker.
Why do you need video card drivers?
Yes. Many video card's will be recognized by Windows XP, and will run corectly without installing drivers. To have optimum performance, always download the latest drive from the manufacturers website. If you don't have the drivers on a CD or on your machine, this works also. I always use the latest driver from the manufacturer.

How are subject directories different from search engines?
While search engines and subject directories both help to find information on the internet, they have several differences. Subject directories are hand picked by people and allow you to browse by category. Search engines allow access to billions of websites and use algorithms to rank the websites according to how relevant they are to your search. Quality of websites is not evaluated by search engines.
How does a computer printer works?
When a text or image is entered into the CPU, it produces a series of varying voltages. This controls a LASER diode in the printer. This emits flashes of light which are directed by a rotating mirror scanning device to the precharged photoconducting drum, when it falls on the precharged photoconducting drum. The area corresponding the text or image will either be neutralized or oppositely charged. A plastic toner powder which has the same charge as the background is sprayed onto it. It only sticks to the text or image and is repelled by the background. A fresh paper is now pressed onto the toner. When the paper leaves the drum it is heated by the fixer so that the toner melts and sticks firmly on the paper.
What are Memory chips that store permanent data and instructions- the data cannot be modified?
chips with memories are worrying. don't eat them or they will lose their memory!
How many telephone companies in the us?
It really depends on what you want to know, there are several different classifications of telephone companies, there is the RBOC (regional bell operating company), ILEC (incumbent local exchange company), CLEC (competitive local exchange companies) and independent phone companies. That really is just the hardline companies, with the popularity of wireless carriers, the number is just going up.
In 2000, I had to get a Y2K certification letter from each carrier in the entire state of Kansas, I know at that time, there were 62 phone companies in just Kansas, cant imagine what the total is for more populated states.
Which company offers the best broadband prices?

Which year did the first man land on the moon?
July 20 1969 was the first manned mission to land on the Moon.
It depends on whether you are referring to a server or host machine, an individual workstation and/or your browser settings. Proxy settings dictate how a standalone workstation is connected to the internet; however, most workstations that are not standalone rely on a dedicated server or host machine (which acts as an internet gateway) in order to access the internet.
Corporations use SSL Proxy settings to protect their corporate network as well as their intranet (i.e., internal network) from external threats that are most prevalent on the internet.
This is only a high-level description. More information about how servers are configured to connect to the internet, is available in the related link.
What are similarities and differences of RAM and Eprom?
Why is digital technology preferred to analog technology in communications technology?
Why digital communications and what its advantages over analog communication ,first you have to know what is the difference between analog signal and digital signal. Analog signal analog signal is continuous time signal i.e. it has a value at any moment of time and it has infinite number of valus , such as dinusoidal signal ,you can substitute X with any value and you will have an value in Y in the follwing sin relation Y=sin(X). 1-Noise and destortion immunity:-when analog signal is transmitted in free space for long distances it will be distorted and no an ideal recovery done in receiver to recover the exact signal which transmitted ,but in digital communication digital signal consist of 2 levels only zero or one (not like the analog one , it has infinite numbers of values or levels at each period of time),so digital signal can be recovered easily and excactly like transmitted one. Hint : Device that used to pattially recover the analog signal after a certain distance is called repeater ,from its name it receives transmitted analog signal and filter it and amplify it and transmitt it),but in digital transmission it is different ,the device used for recovering digital signal which transmitted from acertain distance is called regenerative repeaters ,it receives transmitted digital signal and recover it to regenrate a new exact signal like received one then retransmitt it for further distance. 2-More privacy and security due to encryption. 3-Error detection techniques can be used and correction as well. 4-Easy for processing and applying multiplexing techniques. 5-Low cost. 6-Transmission rate can be changed easily. 7-Digital hardware implementation is flexible and permits the use of micrprocessors, digital switching elements and layer scale.

Does a tv have computer technology in it?
Yes, modern TVs rely on computer technology and built in firmware to operate.
How does the use of internet by an e-business enterprise support their e-commerce activities?
iNternet is a system that connects all of the computers and phones in the world. iNternet ismanaged by the iFairy, who is the all-mighty being that makes sure that good people get iNternet and bad people dont. It is spelled like iNternet in honor of the iFairy, so be sure to always spell it that way; if you dont people will joke about you behind your back. There are a lot of people who spell it wrong, and they made an infective program called Internet Explorer. Do not ever use this program or it will erase all of your computer's memory. Read the bolded letters in order ;)
MS in InfoSec means Master of Science in Information Security; It is a Master Degree Program offered by different universities in Europe and USA etc.
What are some important factors to consider when evaluating ready-made software packages?
It would be helpful if you specified what type of software you are referring to (accounting, databasing, etc.), but I will list some general guidelines. This answer is based on a medium to large sized company buying software for many users, but most of it applies to any software-buying situation.
* Price How expensive is the software per license? Can you get bulk discounts if you are purchasing many licenses? Do you have to but any extra things, like servers or server software? Does your budget allow for all this?
* Features Does the software do what you need it to do? Does it do it well? Can you try it before you buy it to make sure it suits your needs?
* Support Is the company well established? Does it have a dedicated support team? Can they be reached 24/7? Are they competent? Does the company offer to help with setup and deployment of the software?
* Competition Is there any competition? Are there comparable products that may be an alternative to your current selection? How does other software compare to your current selection? Is there any cross-compatibility? Do they have better features or deals?
The most important thing to do is talk it over with peers and superiors. Get several opinions and try to be objective. Also, even after you pick one software, re-evaluate your situation. Other options might pop up that may work better for you.
How technology has made life easier?
technology has made life easier because we can use the phone to talk to people instead of face to face. we can watch tv instead of just sitting their wanting entertainment
What is the name of the professional who creates websites?
You should try such sites like www.troublefreewebsites.com, they set up your site and your email, and its all hosted for free forever! (There is a small charge approx $170)
This site is designed for those who would not consider themselves very "Tech Savvy," but wish to be able to get a website up and running whether it be for business use or personal. The whole setup process involved in creating a website can be quite complicated and can take a long time to learn to configure correctly if you don't know what your doing.
The easier option would be to just pay someone to do this for you but prices for web site design and web hosting can be very costly. If you are a small business or intend on using your site for personal use, this can be a lot to ask. Now I will admit, with most of those companies you do get very decent websites, products and support but what they offer, is to remove all the extra costs and just give you the cheap and cheerful option. So if that is what you are in the market for then you then that would be the right place. :)
What ethernet port is used to connect a computer to?
An Ethernet port appears to be almost identical to a telephone jack, although it is slightly larger. There is often a symbol beside the port with two boxes on the bottom and a box on top, with a line connecting all three.
How do you convert 12volts power supply into 24volts?
For AC it is relatively simple from an electrical point of view. All that is required is a transformer. Even if there are other electronic solutions, unless there is good reason. Stick with the idea of a transformer since the only bad part about transformers, compared to other sophisticated electronic methods are: weight, size, stray magnetic fields but that's about all. They are robust and still very reliable and easy to use. They are available in high power units, they are easy to replace, easy to reconstruct and easy for anyone to understand it's function for later.
Transformers can step-up or down voltage depending on the ratio of windings between the primary (input) and secondary (output). If you have access to a company that wind or make transformers (Most modern city areas have such companies) One can contact them for more advice. What you will need is your primary voltage, secondary voltage, the VA
- VA is the Apparent Power which is the not the real average power since it does not include the power factor. It is only the volt(ac) x amps(ac) of the secondary. The general idea is that the power you apply on the input should be close to the power you get from the output, even though you do have some power losses (Eddie current, heat, ext.)
Then you also need to specify the type of transformer. Normally an E-Core transformer can be used. E-core is a transformer with a metal core with laminations shaped like an "E" to reduce Eddie Currents. More information can be obtained from:
http://en.wikipedia.org/wiki/Magnetic_core
If you need 24Vac for a 100W lamp then the current will be 100W/24V = 4.16A so basically you need a (24V x 4.16A) =100VA step up transformer with 12V primary and 24V secondary in a E-core style. Also note that the primary current will then increase to 8.33A since 100W/12V = 8.33A. It might even be a little bit more but never less. One cannot create energy.
If you mean on television it is so young viewers who are watching do not pick up the words that are being said and start using them in an uncivil manner.
