What kind of job can you get with an A plus Certification?
These days you'll be hard pressed to get much of anything with it. Most markets have become so overflooded, employers won't even look at you for a basic tech support position with out a B.S. in some IT related field, your A+, Net+, MCP, CCNA or any combination of those and the other several hundred IT certs.
Your best bet is to aim for a smaller company and possibly a smaller salary than you would initially like to start with. Realistically, in Atlanta, for example, you could probably land a entry level support job making between $25-30k salary or $12-13.50/hour plus some benefits. Not sure what the market rates are in other areas, but with the cost of living in metro Atlanta, you can live off of that. Not comfortably, but you can make it.

Why windows takes so long to start up?
Most of us have had a brand new computer at one time. It's a great feeling. You boot up windows and within 30 seconds you are surfing the net, checking your email, or playing your favorite game. 10 months down the road things aren't so nice anymore. You power up your computer and it seems to take forever to load.
Even when you are careful about what you install it seems that each day it takes longer for it to boot. It's not your imagination - and there are a couple of good tips to keep your boot time short and sweet.
As always - backup your system before you start any of this. If you make a mistake you might need to restore from backup.
Update (09/08/2006) - There has been some controversy about the prefetch folder. I think this issue needs to be looked into. I did have a reputable source for this information: It was the "Windows XP Annoyances" book by O'Reilly. Page 210. Titled "Keeping an eye on prefetch"
1. The prefetch cache
The first tip I want to talk about is the windows prefetch. Windows XP has this feature that loads commonly used programs - at boot time.
Here is how it works: Yesterday you used MS Word, and Duke Nukem 3D. Today you boot your system to check e-mail. It sees parts of these two programs in the prefetch folder and loads them into memory before windows completes the boot process. The benefit is faster application launch times. If you really wanted to use MS Word, it would pop up really quick when you double clicked on it.
The problem is most people have been running windows for years, and the prefetch gets clogged with stuff that you almost never use. Windows takes forever to boot because it is prefetching a 1.0 copy of Napster, and you just want to check your email before you have to go to work. Anyway, there are a few things we can do to tweak the prefetch cache. One method is to disable it partially, and this can be done quite easily. Simply browse to the windows folder (Ex: C:\Windows) and under there you should see the prefetch folder. Go into the prefetch folder and delete all the files (Careful! It should look like this c:\windows\prefetch)
The first thing to note is the next reboot will be slow. This is because windows needs to relearn the prefetch for system files. Subsequent boots will run much faster since the sludge of programs has been removed, and only new ones are in the cache.
The trouble is that it will only help you for a while - until the prefetch gets clogged up again. We need to edit a registry key to tweak it. Open regedit and browse to this key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
Under this key you should see a value named: EnablePrefetcher
It has 4 possible values:
0 - Disabled : The prefetch system is turned off.
1 - Application : The prefetch only caches applications.
2 - Boot : The prefetch only caches boot system files.
3 - All : The prefetch caches boot, and application files.
We don't want to disable it entirely. This would actually make boot times *longer*. This is because this feature is also used to speed up the loading of boot files. That is why we are going to pick the number 2 option. It allows us to keep the advantage of caching system files, without continually clogging the system up with applications. Set the value to 2 and reboot. The 2nd time you boot it should boot much faster. Remember that the side effect is that launching individual applications once windows has loaded will now be slightly slower.
2. Hard drive fragmentation
Over time your hard drive will become fragmented. An over-simplified explanation of fragmentation is when your files and folders are not all stored in the same spot. For example lets say you had a large movie file. If it were fragmented the first 5 megabytes are at the beginning of the hard drive, and then next 5 are at the end. It takes longer for windows to read the file than it would if it were all in the same spot. The point is that if each file is stored in a linear fashion, and the drive does not have to move all over the place to read it - it will load faster. XP has a built-in defrag tool, and it is simple to run. Open "My Computer" right click on the boot drive, and go to properties. Now click on the tools tab.
Click "Defragment Now" and a window should appear. Before you click on the "Defragment" button you want to close all applications and be aware that it might take hours to complete. If you leave something running it might keep windows from completing the defragment operation. Click on the defragment button and you can walk away. Or you can watch it defrag your hard drive:
3. Disconnected network drives
I am using networked drives all the time. If you have ever put your machine on a network and connected to a shared drive, this can slow you down too. If you have a drive that is still mapped, but cannot be reached it will slow down windows during boot time. This is because windows will wait…wait…and wait some more for the remote server to respond. To clean these out open "My Computer" and go to the tools menu. Click on "Disconnect Network Drives" It will open a window,
Click on the drives you no longer need, and click OK.
4. Spyware & Adware
These can have a big impact on your start times. If your PC gets loaded with spyware, it spends a large portion of its boot time making sure those pesky programs are loaded and ready to throw popup adverts at you all day. To check and clean your system of spyware there are three free programs that I highly recommend:
1. Microsoft Windows Defender
2. Ad-Aware
3. SpyBot Search And destroy
5. File and Printer Sharing
One other item that can significantly impact is the "File and Printer Sharing" feature within windows. Obviously, if you are sharing your printer, or folders you don't want to disable this - so this tip is not for you. If you never use it, then why waste your time waiting for it to load?
Here is how to turn it off:
Go into the control panel. Click on "Network Connections"
Now right click on "Local Area Connection" and click on properties
Uncheck the "File and Printer Sharing for Microsoft Networks"
Click OK, and reboot.

Will intelligence of computers threaten the freedom of human beings?
This is one of the greatest questions. We can be sure that people will surrender their liberty as they have many times in the past, when it appears security and comfort can be gained. But every great leap in technology brings with it both risk and promise. As Kurzweil says--in the future computers will make convincing claims that they are conscious and intelligent, and we will believe them! I suspect we will see great things beyond our imagining today.
What are the advantages of using a computer to calculate profit and loss?
Speed and reduction of human error. (That's assuming that your computer program that is providing the profit and loss report is set up properly, which again would be human error if it isn't.) idk wat r we talkin bout again
Why should power on self test happen when no terminals are connected?
Power on self test in electronics equipment or computers is done to validate if all the critical parts of the device are working as desired when it is turned on. Any thing wrong internally or on an interface is typically reported as a failure on power on self test. What all is tested depends on how elaborately the power on self test has been designed.

Why 1MB is equal to 1024KB explain in detail?
Because 1024KB makes up 1 MB, and 1024B makes up 1KB etc. This is because , "computer language" is binary (0's and 1's) and thus the closest to 1000 that can be achieved in just one multiple (i.e. 10000000000 or 000000001000) is 1024.
What does it mean 'enter your desired job title'?
It simply means what your looking to be for ex. Cashier
Most companies use standard job application forms so they just need you to identify the role you wish to apply for. Sometimes there is a job reference number too which will appear in the job advertisement and it is important to quote this in your covering letter and on the application form if it is required.
The primary threat from a buildup of dust inside a computer is called what?
Not sure, but I would guess overheating?
Is there a programme that will click on a site a few thousand times for you?
Yes,
Although if you are using this to gain more revenue from ad companies they will notice and ban your account.

What is the best contribution of computers in space research?
the really old ones
...hmm i suppose computer simulations of rockets trajectory was kind of a big breaktrough?
If a computer understands numbers how is it possible for us to type using letters?
The data is internally stored as bits (ones and zeroes). To interact with humans, the keyboard uses letters; but as soon as you press a key, a series of electrical circuits are activated, and this is represented by zeroes and ones (for example, zero when no current flows, and one when a current flows - or the other way round, depending on the convention used).
I deactivated my account and when I decided to use it again I just logged in the same way I always did. I can't remember if they prompted to me to change my account settings or not but that's how I got my account back.
What is die and wafer in CPU components?
A wafer is a disc of pure silicon metal cut from a manufactured rod. It is usually more than 150mm in diameter and less than a millimetre thick. It is then processed in vacuum equipment where layers of metallic, insulating and semi-conductive material are deposited on the wafer in patterns. these patterns are designed so that the completed device will have specif functions, like an amplifier or a Central Processing Unit (CPU). there are multiple devices on one wafer. The wafer is then cut up into individual devices, each one known as a die. These dies are then "packaged" into connection arrangements to make them easier to handle and connect to the motherboard.
