What is mean by voice activated dialors?
Voice Activated Dialing (VAD): Being able to dial out on a cell phone or in-line phone via a voice command. There are phones that can be answered via voice, but others require activation of a switch (either remote or in-dwelling) before dialing out. VAD would allow a high level quadriplegic (someone who can only move their head due to a spinal cord or brain injury, but can use their voice) to dial out on a phone for emergency access. Evidently, there is a model of Blackberry that has the capacity to dial out via a voice command, but I have not seen or used it personally.
Where can I purchase a touch screen laptop?
VAIO, Dell and Gateway have new competitive touch screen computers available. You can purchase them directly from the companies to get the latest and best opening deals. It depends on the functionality and the types of features within a system that someone may be looking for in a computer. There is two new one just hitting the market, called a Lenovo IdeaCentre touch screen and a computer made by Vizio. They are said to be an all in one unit. Which means that they are set up for features that include gaming, sound and videos. The decision would be whether or not to have a laptop styled or desktop unit.
How do you make accent marks on the computer?
To use the Extended ASCII characters, you'll need to hold down the ALT key on the keyboard, hit a combination of numbers on the num pad on the right side of the keyboard, then release ALT. ƒ is created by holding ALT and pressing 1 then 5 then 9, and releasing the ALT key. There is a complete list of the characters you can add available here: http://www.cdrummond.qc.ca/cegep/informat/Professeurs/Alain/files/ascii.htm
How do you change low resolution to high resolution?
Sometimes our customers give us JPEG pictures at 72DPI. Even worst is when these pictures need to be enlarged, ending up with something like 16 DPI…
For the cases where there is no other sources, we have refined a process to be able to print at 720 DPI on our large format printer with satisfactory results, commonly so good that a normal viewer will not discern the difference with a picture originally at 150 or 300DPI.
But let's start with pictures of a real case example that we handled just last week, before giving you the recipe
cropped and zoomed detail of the original picture and improved picture, both zoomed 400% to see the defects on a screen resolution:
Original PictureAnd now the same area after our processing
Improved PictureQuite impressive, right ? And remember this is a 400% zoom i.e. the improved image really have no scales and almost no blur at 100%.
As can be seen, while you can't really generate details that are not in the picture, you still can greatly improve the actual aspect by applying a few simple techniques, trying and choosing them on the final effect you want to achieve.
Here are the details for Photoshop but they should be applicable to others image processing software.
The simpler and usually starting point is to increase the resolution by step [instead of in one time], ex: double from 72 to 144 to let's say 360 than 720, using different smoothing algorithms.
I also recommend to start your process by changing the depth from 8 bits to 16 bits before doing these resolution increased, and to revert back to 8 bits only at the end, right before printing. This should reduce the moire and flat surfaces.
And you can do some final sharpening/blurring and noise reduction/noise addition as the last step[s].
They are also a few plug-ins available that claim to achieve excellent results. I tried them, and while they results are better than just doing a simple pass DPI increase, I prefer my process that allow me to proceed stage by stage and reach my expected level of quality in a more controlled manner.
This will work really nicely for an originally good 72DPI picture, like the example above, and is time intensive, not to mention you need a strong CPU, lots of memory and better a SSD if your picture size is big. So, I do this as part of my preparation process before printing, since I always print files that I have pre-converted to the right resolution, color mod/profile and saved as TIFF, cause I don't trust the RIP engines
If you start with a low quality level JPEG picture than it's a little bit more challenging, you better start by applying JPEG removal artefact algorithms.
This is the kind of thing we do on a daily basis for our customers as part of Plixo's ultra large format printing services, most of the time we don't even tell customers about it but they tend to notice and ask how we manage to get such results
Hope this helps.

What are different types of linker?
Linking is the process of combining various pieces of code and data together to form a single executable that can be loaded in memory. Linking can be done at compile time, at load time (by loaders) and also at run time (by application programs). The process of linking dates back to late 1940s, when it was done manually. Now, we have linkersthat support complex features, such as dynamically linked shared libraries. This article is a succinct discussion of all aspects of linking, ranging from relocation and symbol resolution to supporting position-independent shared libraries. To keep things simple and understandable, I target all my discussions to ELF (executable and linking format) executables on the x86 architecture (Linux) and use the GNU compiler (GCC) and linker (ld). However, the basic concepts of linking remain the same, regardless of the operating system, processor architecture or object file format being used.
What are the importance of computer in a large scale business?
In a nutshell, if i can say, it is Tremendous. Most of the Businesses today eat, breathe, live, see and do everything else thru or around computers. Just a small example, consider - can a business stand without having a computer to send a small piece of mail to it's client. The Answer is a Big No. More or Less, all businesses need it.

Why do computers impact humans and their life?
The computer is making the life more difficult than pre-computer era is mainly because no matter how smartly you build the instructions / rules for computer to run it still the humanly written code that would never be perfect.
Computer runs on formulas and applied the formula without considering the seasonal changes. Even if it is possible to compute a formula to depict the real-life scenarios, it would take huge investment that 99% of population would not able to afford.
E.g. Computer are computing Grocery items prices, computers are computing Salaries, computers are preparing budget, computers are used to propose "Maximum Retail Prices". People are doing calculations on software (e.g. MS Excel) that itself are not error-free plus the knowledge on how to use the MS Excel (constructing formulas) are also not same for every individual. If you applied a minutely erroneous formula to long list of grocery items it will go unchecked by Humans (because human usually checks totals) and if it gets approved by Authority, the population has to bear it. Wide-spread implementation multiplied the impact.
Practical Example:
Cost of Banana $0.99
Consumption of Banana 100,000,000
Authority Approves the Price $1 (because MS Excel rounded off 0.99 to $1)
Now each banana is $0.01 gets expensive (without any reason) increasing the inflation of $1,000,000 unnecessarily.
Companies happily printed the price of $1 on Banana packaging (considering it cost-advantage and higher profits) but the population who will be consuming it will suffer. Such minor $0.01 price-increase will go unnoticed from both end "Consumer" & "Producer".
Note: This is the example of only one-item, do not forget the numerous products we are using on daily basis.
Similarly, previously people write "Postal Address" by ball-pens / pencils now, they are printing it from computer (using Electricity, using computer equipment, using printer, using Paper, Using "Glue to paste it on packet".....it all adds unnecessarily costs, and the consumer has to bear this added costs knowingly or unknowingly
I would really appreciate any thoughts on my perception, whether I am right or wrong?
Which mode BIOS must be used for 10 GB hard drives?
If your 10GB hard disk is not detected, you dont need to change any bios mode. The motherboard will have problem detecting the hard drive. Search for your bios updates to get your hard drive detected.
Can hackers turn off your computer?
Of course not! No one can access a machine while it is powered off or not connected to the Internet. A hacker MAY however insert code into the master boot sector of the hard drive, so that whenever the computer is turned on, the code executes and carries out malicious actions.

Base 16 numbering is called 'Hex' or 'Hexadecimal'. Base 8 numbering is called 'Octal'. Base 2 numbering is called 'Binary'.
Doing what to the computer opens you user account and makes the computer available for use?
If you're asking about the password of the user account, only the person who created the account would be able to answer that. If you forgot your own password, I'd recommened contacting a local computer repair store to help you. There are ways to retrieve the password, but too detailed to list here as well as security reasons.
What is the software that keeps the network safe from hackers and viruses?
To keep your computer safe that would be an Anti-Virus Software. To keep a network safe you would encrypt your data over with a VPN or use another type of secure dedicated IP to prevent break ins.
The cloud is the new name for local servers that companies such as apple or amazon own. The purpose of these servers is to free up space on your own computer by storing your online e-purchases in an account specific to you. That way if you purchase a song or e-book and accidentally delete it, you can go to your cloud and re-download the item without having to repurchase the item.
Does Ikea sell white computer desks?
"Walmart sells a variety of desks in different colors. However, they do not all come in white. Local store availability may be limited. Walmart does have an option where you can order online and have it shipped to a local store."
What is the difference between Ram and a processor?
RAM=Random Access Memory, used for fast swapping of data on computer
Processor= a small chip on the motherboard performing millions+calculations a second.
your computer uses ram all the time to keep background apps open, and to basically run everything.
your computer uses your processor when you do graphic intensive or calculation intensive things, such as gaming, video converting, multiple things at once, like running Photoshop, a video encoder, your internet browser, and watching a movie.
now if you want to know which to upgrade, it depends on the current status of your computer, and your aim of the upgrade.
