Personal computer (PC) microphones are one of the computer accessories, which enable video conferencing, Internet chat, etc. They are plug-in-components and can be easily attached to computers. PC microphones make use of sound cards, which amplifies the signals from microphone. PC microphones are reasonably priced and ranges from $10 to $60. These microphones are connected to the computers using cords with various lengths and one has to purchase considering the length of the wire keeping in mind the purpose. Powered mics are used in PCs as they generate strong signals.

Unidirectional mics or omni directional mics may be used in PCs. Unidirectional mics pick up sound waves from a single direction and omni directional mics pick up sound waves from varied directions. The features to be noted before going in for a purchase are accuracy of these sound cards, noise filter options, comfort of the headsets, the length of the cords, and the mountability of the mic on the monitor.

There are two types of PC microphones based on the way they are connected to the computers. They may be connected to sound cards or to Universal Serial Bus (USB). The quality of recording and audio output varies depending on the type of mic selected. When sound cards are used, the recording process is done within the computer itself. The quality of recording is not good in this method, because of the internal noise caused by the computers. When the mics are connected to PC’s by USB, the recording is done externally and this serves as an advantage regarding the quality of the recording. The process of recording is free from the internal noise of computers and so high quality recording is made possible. Before purchasing and installing a particular type of mics, many things have to be taken into consideration. They must support any future technological improvements.

PC Security

To have PC security is important in this day and age of Internet fraud, scams, spy-ware, and viruses. It is a problem that all computer users must face. The massive challenge of PC security is driven by the explosive growth of malicious programs such as Trojan, key loggers, and root kits, coupled with critical drawbacks of the traditional, signature based products. Your PC security is far too important to leave to chance. In short, the most important thing to remember about PC security is that it begins with prevention.

We found out that the best way for PC user to know and understand PC security is to give them the right information so that they have a basic understanding to protect their computer threats from spy-ware, ad-ware, viruses, hackers and other security threats. This information is vital for the non-technical savvy, protecting you & your family on line

Virus

Computer virus are basically program modifications made to certain files that are designed to replicate on their own (say, when the host program file is executed). It is a small program that searches the computer for another resident program, makes a copy of itself, and inserts the germ into a healthy program. If you do, chances are terrific that your PC contains viruses, Trojan, ad-ware, and spy-ware, and that your PC is being used, without your knowledge, to send viruses to hundreds of thousands of people every month, spamming out to them on an infected PCs mailing list, so odds are, if you get one, it’s going to come from someone you know.

Viruses and spy-ware can also take the form of various Internet applications that you had never suspect were malicious. Virus coders are really smart guys, and they do their bad job excellently. The number of viruses and malicious programs out there is staggering. Over 1000 new variants of viruses and other malicious programs are created by the “black hat coders” each day.

To put it simple, a virus is meant to damage files or change them, while spy-ware silently collects information or establishes loopholes in Internet connection settings to allow secret communication with the remote servers. Like stealth, majority of virus and spy-ware activity takes place quietly, without your knowledge.

Prevention

Most PC users did not know that spy-ware and viruses may be hidden in programs downloaded from the Internet. Viruses are designed to attack your PC through these programs.

The basics of home PC security start with an anti-virus program and a firewall. Install anti-virus software. Anti-virus software detects and removes viruses, which attach themselves to a program or file to spread from computer to computer. By installing anti-virus software and keeping it up to date, you can help keep your computer free from these destructive viruses and avoid spreading them to other computers. Scan your PC with your anti-virus software regularly and be careful of what websites you visit and of installing free software that they may offer. Besides anti-virus software, anti-spy-ware and anti-spam programs are essential for Internet user.

Most Virus and Trojan scanner soft-wares are well able to detect malicious files but are not very efficient in removing them if they have it. Will it stop a virus from corrupting or destroying your important documents? Of course, PC security software companies claim many anti-virus solutions, both for personal PCs and business networks in promoting their products.

Anti-virus soft-wares

Can we call the anti-virus as “best of the best”. When a brand new malicious virus is released onto the Web, no signature-based anti-virus program will detects it for several hours up to several weeks. That is why in real life the performance of any anti-virus program is questioned with its usage conditions. Most only detect about 90 to 95% of all known viruses. Your virus software may not even know they are there. Secondly, virus software will seldom stop hackers gaining access to your computer. And once the computer is infected, can we blame the anti-virus for that. No anti-virus can ever be relied on to give 100% protection. Just previewing a virus-laden message can infects your PC.

They’re always rises the question ‘Why anti-virus A is better than anti-virus B’. Reviewing ANY anti-virus is a tough task. Each anti-virus brand on the market has its avid supporters and furious haters. Some brands of anti-virus software are known to bring down the performance of your PC to its knees, they also often PC crashes and erratic program behavior.

Good anti-virus software scans incoming e-mail, downloaded programs, and several other things that effectively by-pass your firewalls. But comfortingly, all the major anti-virus software providers have the information alerts on their homepages, provide updates downloads to their virus list and program.

After you have your PC or computer for several months it unfortunately starts to run slower and slower.
There are a few things you could try to get your PC or computer running faster.

You could delete software, programs and files you no longer use or need which will free up some disk space. Then you could go ahead and delete internet temporary files and cookies. A good idea also is to regularly delete everything in your recycle bin which also frees up disk space on your PC.

Another step you want to think about is making sure you do not have too many programs running in the background when you start up your computer. Also, try not to have too many programs open at the same time that you are not using or do not need at that moment.

More often than not, even after performing these steps, your computer will still not run faster which can be very frustrating.

Many people do not know that a computer needs to maintained on a regular basis just like a car. In order for it to run at optimum speed, your PC needs to be serviced. Chances are you are experiencing a registry problem. The registry is the main brains of your computer where all the information you want to get to is stored.

Over time, the registry becomes cluttered with useless files and unnecessary ones. Your computer can get clogged up which, in turn, your computer’s memory will become fragmented and disorganized. So your PC will begin to slow down and you won’t be able to load or run your programs. This can cause major problems which are no fun at all.

So why clean your windows registry? A good registry cleaner scans and fixes registry errors and safety deletes all duplicate files. In addition, a registry cleaner will run a defragmentation on you registry memory so that all the data on your PC is properly organized and not just spread out all over. What is a big plus in my book is that you can feel safe that a good registry cleaner will not erase something critical that you need or cause any damage to your computer. Most people are scared they will accidentally delete something or may do harm to their computer.

So if you want your PC or computer to run faster and want a safe way to do this, then you could look for a good registry cleaner online. Of course, there are hundreds of them out there on the worldwide web, so which one do you choose?

Help, my PC keeps freezing. That is a common question a lot of computer users ask, when they face one of the most frustrating computer errors. Your PC screen freezes while you are finishing an important project, running a program, playing games, or browsing the internet.

So what can you do at the moment your PC freezes up? Pressing CTRL+ALT+DEL at the same time, will open the Task Manager, which shows you all the programs that are currently running on your computer. Select the programs that have a status “Not Responding”, and click “End Task”. This will close the not responding programs. Be aware that you will probably lose all unsaved data. This is the price you have to pay when your computer keeps freezing up.

Why does my PC keep freezing up?

There are several reasons why your PC keeps freezing up. One way to eliminate your computer from freezing is by finding its root that is the Windows registry. The windows registry is an important component of the Windows operating system. Without it, Windows would not be able to run. The registry keeps track of everything, e.g. where the files are located, user preference, file associations, shortcuts, uninstall entries and much more.

When the windows registry starts to become very large, your PC’s performance can decrease and it can cause computer freezing.

How To Fix Computer Freezing?

Running a registry cleaner, such as RegCure, on a regular basis will keep your registry clean and free of damaged entries. RegCure is a Microsoft Windows tool that will fix Windows errors by analyzing your registry for corrupt, obsolete, and missing entries resulting from unsuccessful installations and un-installations, disabled drivers and spyware programs.

It takes about 2 minutes to scan your Registry. You may be surprised what you find as it is not uncommon for hundreds even thousands of errors to be uncovered. Cleaning a corrupt and cluttered Windows Registry will not only speed up your PC, but also stop you from saying “My PC keeps freezing”.

Either building website’s or creating power point presentation’s or whatever the project is.

There a few other reason’s that converting a TV into a PC monitor is catching on. For one, many like using the surround sound or even the stock TV speaker’s when watching movies or listening to music download’s. Or you can switch over to a show or football game while working on whatever project your stuck doing. Not to mention, you dont have to worry about getting food or drink’s all over the keyboard or mouse.

When your used to staring at the standard size PC monitor , it can be quite exciting to read your email on a 36 inch Television screen.

It truly is fantastic to flip your TV into a PC monitor. It’s even better when you try it on your Big Screen. If you have seen it before , than you already know. If you haven’t , then you might want to learn how now. It’s not too hard , but writing this down might be a good idea.

Basic Conversion Instructions

First thing’s first, you are going to need a “VideoCard”. A video card is simply hardware that is used to generate and output images to a display. Some main function’s of the video card are video capture, TV tuner adapter , Mpeg decoding, connecting multiple monitors and connecting joystick’s. You can usually purchase one for around $30.00. That will get you a 256 MB card that is more than enough for most function’s.

Assuming that your PC has an “S-Video” port ,you will need to plug an “S-Video” cord into the “S-Video Out”. Then connect it to your television set in the “S-Video In” port. For sound you will need an RCA cord. Hook the RCA “Red and Black” into to the corresponding port’s on your TV. Make sure you hook up the opposite end of the RCA into your PC or laptop. If you dont have one , your PC speaker’s will work for this.

Now we are ready to adapt the PC setting’s and Video Card setting’s.

Right Click anywhere on the desktop screen Click “Properties” Click “Settings” Then Click “Advanced”

Now. in your “Graphic Card” setting’s you will High light the “Display Settings” tab. Once there choose the “Single” display option. The dual will leave your PC screen blank or all you will see is the screen saver.

Next select the “Clone” option for the TV. That will send the PC signal through the “S-Video” cable to the TV screen. Now press your “TV-Video” button on your TV remote. What you are searching for is the “Video” option that will display your PC’s screen. Once you have the Money Shot , (Well , you know what I mean) that mean’s your TV is set-up correctly. That also mean’s it is time to click the “Apply” tab in your “Video Card” setting’s.

That’s it , click “Yes” to confirm and you are done. It’s time to have some fun with your PC to TV connection. Once you can perform this operation like the “back of your hand” , it’s one of the coolest function’s available.
