The two main categories of processors are 32-bit and 64-bit. The type of processor a computer has not only affects its overall performance, but it can also dictate what type of software it uses.

32-bit processor

The 32-bit processor was the primary processor used in all computers until the early 1990s. Intel Pentium processors and early AMD processors were 32-bit processors. The operating system and software on a computer with a 32-bit processor is also 32-bit based, in that they work with data units that are 32 bits wide. Windows 95, 98, and XP are all 32-bit operating systems that were common on computers with 32-bit processors.

Note: A computer with a 32-bit processor cannot have a 64-bit version of an operating system installed. It can only have a 32-bit version of an operating system installed.

64-bit processor

The 64-bit computer has been around since 1961 when IBM created the IBM 7030 Stretch supercomputer. However, it was not put into use in home computers until the early 2000s. Microsoft released a 64-bit version of Windows XP to be used on computers with a 64-bit processor. Windows Vista, Windows 7, and Windows 8 also come in 64-bit versions. Other software has been developed that is designed to run on a 64-bit computer, which are 64-bit based as well, in that they work with data units that are 64 bits wide.

Note: A computer with a 64-bit processor can have a 64-bit or 32-bit version of an operating system installed. However, with a 32-bit operating system, the 64-bit processor would not run at its full capability.

Note: On a computer with a 64-bit processor, you cannot run a 16-bit legacy program. Many 32-bit programs will work with a 64-bit processor and operating system, but some older 32-bit programs may not function properly, or at all, due to limited or no compatibility.

Differences between a 32-bit and 64-bit CPU

A big difference between 32-bit processors and 64-bit processors is the number of calculations per second they can perform, which affects the speed at which they can complete tasks. 64-bit processors can come in dual core, quad core, six core, and eight core versions for home computing. Multiple cores allow for an increased number of calculations per second that can be performed, which can increase the processing power and help make a computer run faster. Software programs that require many calculations to function smoothly can operate faster and more efficiently on the multi-core 64-bit processors, for the most part.

Another big difference between 32-bit processors and 64-bit processors is the maximum amount of memory (RAM) that is supported. 32-bit computers support a maximum of 3-4GB of memory, whereas a 64-bit computer can support memory amounts over 4 GB. This feature is important for software programs used in graphic design, engineering, and video editing as these programs have to perform many calculations to render their images.

One thing to note is that 3D graphic programs and games do not benefit much, if at all, from switching to a 64-bit computer, unless the program is a 64-bit program. A 32-bit processor is adequate for any program written for a 32-bit processor. In the case of computer games, you’ll get a lot more performance by upgrading the video card instead of getting a 64-bit processor.

In the end, 64-bit processors are becoming more and more commonplace in home computers. Most manufacturers build computers with 64-bit processors due to cheaper prices and because more users are now using 64-bit operating systems and programs. Computer parts retailers are offering fewer and fewer 32-bit processors and soon may not offer any at all.

Disable Unnecessary Hardware

Every piece of hardware leeches power from your battery, so disable anything you don’t immediately need. External devices, such as flash drives, SD cards and an external keyboard or mouse, can simply be unplugged. Windows® 8.1’s PC Settings offers an Airplane Mode to disable integrated wireless and Bluetooth adapters and enables you to turn off your camera. Device Manager optionally disables hardware that’s not customizable through PC Settings.

Disable Unnecessary Programs

Every running program makes your power-hungry CPU and RAM work a little harder, so when you need extra juice, don’t multitask. Close unnecessary windows or end unused processes in the Task Manager.

Optimize Your Screen

That big, bright LCD screen hogs most of your battery power, so reduce its consumption wherever possible by dimming the display. You can also lower the screen resolution to reduce the strain on your graphics adapter.

Use the Power Saver Profile

Selecting Power Options’ Power Saver profile turns off the screen and puts the computer to sleep after a short period of inactivity. However, manually choosing the Hibernate option avoids the waste of inactivity and conserves more power than sleeping. The option to hibernate when you press the Power button is available in Power Options.

Optimize Your Battery

Power efficiency assumes battery efficiency, so keep your lithium-ion battery in optimal condition by regularly topping off the charge and avoiding a complete discharge. Clean the contacts with rubbing alcohol every few weeks to ensure a solid connection with your laptop.

Other Tweaks

Consider upgrading to a solid state drive that uses less power than traditional mechanical drives. However, avoid adding more RAM unless you anticipate running memory-hungry programs that max out your current RAM and force less efficient virtual memory use.

1. Don’t get too attached.

When you plug your laptop in for the first time, you should make sure to fully charge it once to calibrate it. But after that, aim to keep it between 40 and 80 percent. Apple’s customer care says you should do this to “keep the electrons in it moving occasionally.” Wired has a better explanation of whyhere. But the bottom line is, doing this can help prolong your battery life by as much as four times.

I know that’s easier said than done. Just remember to keep an eye on your battery percentage (usually shown in a corner of your screen) throughout the day. If you leave your laptop at home, then shut it down, close it and keep it unplugged on a desk, not a couch.

You should also fully charge and discharge your computer’s battery at least once a month. Set a reminder on your phone or something. You forked over what I assume to be a ton of money for this thing, so paying attention to it once a month shouldn’t be a problem.

2. Stay cool.

Most modern laptops are made with lithium-based batteries, which should be stored in temperatures between 50 and 95 degrees Fahrenheit. You might not always be able to keep tabs on that sweet spot, so to make things a bit simpler, room temperature is fine.

That being said, there are a few ways you can make sure your laptop isn’t constantly having menopausal hot flashes. You should start by minding its air vents. Most MacBook vents are located on the back of the laptop, near the top of the computer. Whenever you prop your laptop up on your bed, couch or lap, you’re likely blocking the airflow. This, in turn, causes the computer to overheat. And overheating will screw up your battery life.

That’s not to say you should be completely paranoid about keeping it on flat, cool surfaces all the time. But maybe consider moving it to a desk before you fall asleep or head to work.

3. Update, update, update.

Most companies are constantly looking for ways to improve battery life via software updates. In fact, it was one of the main things Apple touted in its OS X Mavericks release last year. You may fear change, but change can extend your battery life. So make sure you have the latest software installed on your computer.

4. Don’t just leave it there.

Maybe you’re in trouble with the law and need to disappear for six months. We understand how these things go. But that doesn’t mean you’re off the hook for correctly storing your computer. You should store it with a 50 percent charge in a consistently cool area. Storing the computer with a fully discharged battery might ruin the battery forever. And storing it with an absolutely full charge might cut the battery’s lifespan short.

Tips for Speeding Up Your PC
Few things are as frustrating as dealing with a slow, sluggish computer. When a computer is brand new, it works wonderfully well. Over time, though, its performance can slowly begin to worsen. This happens for a number of reasons, but the biggest culprits are things like spyware, adware and other computer threats that are unwittingly downloaded along with other content while online. You don’t have to download thousands of MP3s, movies or other items to experience these problems, either – nobody is immune to them. Instead of accepting the situation, there are plenty of techniques and strategies that you can use to make it better – a few of the best ones are outlined below.

Strategy #1: Clean Your Computer’s Windows Registry

The biggest cause of slow, sluggish PC performance is errors and problems within its Windows registry. Adware, spyware and other threats usually target the registry, damaging or misplacing important files within it. When it comes to PC cleaning, a daily Windows registry cleaning should be at the top of your list of priorities. However, this should never be done manually – there are too many opportunities for major errors that could seriously damage your PC’s operating system. Instead, invest in a high-quality Windows registry cleanup program and configure it to run once per day – you won’t believe the difference that it makes.

Strategy #2: Remove Unneeded Files
Every time you log on to the Internet or otherwise use your computer, temporary files are generated. They are usually only needed once; however, they don’t disappear on their own. Instead, they accumulate over time until they are cluttering up your computer’s file system and affecting its performance. While it’s possible to remove these files one-by-one, it’s much easier and quicker to use a PC cleaning tool that’s designed for the purpose. Try to do so about one time per week to keep your computer humming along with ease.

Strategy #3: Remove Unneeded Programs
Like many people, you probably download and try out many different programs each month. How many of them do you actually end up using on a regular basis? Chances are, not very many of them. By getting into the habit of uninstalling unused and unneeded programs, you can keep your computer’s file system a lot less cluttered. In turn, your PC’s performance will improve dramatically. You can optimize your computer in this way by using its Add/Remove Programs feature. Its location varies by operating system, but you should be able to find it somewhere in the Control Panel.

Strategy #4: Empty the Recycle Bin

When you click “delete” on a file or a program, it doesn’t go away for good – not immediately, anyway. Instead, it sits in a kind of purgatory in your computer’s Recycle Bin. As things pile up in the Recycle Bin, your computer can start exhibiting some very annoying problems. If sluggish startups and frequent crashes are occurring with increasing frequency – and your computer’s recycle bin is very full – go ahead and empty it. From then on, get into the habit of doing so about one time per week. This small but important strategy can make a huge difference.

Strategy #5: Perform a Disk Defragmentation

Windows isn’t very efficient when it comes to storing files. It actually splits them up, depositing them into whatever spaces are available. The more spaced apart the pieces of a file are, the harder your computer has to work to make them run. The Windows disk defragmentation system tune-up utility works to piece all of those files back together again. The process is a long one, though, and only needs to be done about four times per year. Set it up to run automatically once every three months. By doing so, you’ll be able to keep your computer running in tiptop shape.

When it comes to keeping your computer running optimally, small but regular maintenance is the best way to go. Protecting your PC only does so much; even the most careful Internet users in the world unintentionally download malicious software from time to time. By using basic system tune-up tools, cleaning your computer’s Windows registry regularly, performing regular file-cleaning maintenance and otherwise optimizing your PC, you should be able to keep it in like-new condition for a lot longer. Even if your computer has been performing slowly for some time, beginning this regimen is sure to produce results. In the end, you’ll be able to enjoy a computer that flies along – instead of one that spins its wheels.

Computers have become a staple of our world, continuously undergoing development, changes and updates. There are pretty a lot of things that we can do with them. A huge part of computer usage comes from personal computer usage. People type, chat, surf the net, watch shows, download files, play games and do a lot of other things in the computer.
People utilize the computer to surf the internet which successively endangers it to a number of unwanted and harmful programs, and viruses. System maintenance is essential to make certain that it is working properly.
The computer system is not so much different from our automobiles regarding maintenance. Just like our engines, we perform typical structure check-ups or bring them to special service outlets to get fixed. Aware of the computer’s significant part in our office and daily life, we should constantly make sure that there are no unwanted matters that could alter or cause it to break down.
Two Kinds Of Maintenance Computers Go Through:

Preventive Maintenance.
Preventive maintenance includes common computer security and cleanups that prevent potential PC errors. Simple actions like scanning, virus removal, disk defragmentation, disk error correction and file organization are applied. Preventive maintenance also includes motherboard and other components clean up to prevent related problems.

Corrective Maintenance.
While preventive maintenance’ devotion to keeping the system safe from potential technical problems, corrective maintenance’ devotion is diagnosing and fixing existing problems. Corrective maintenance may require repairing parts or even replacing them with new ones. Computer technicians are specifically trained to carry on repairs and configuration assistances, but it is likewise advisable to visit computer maintenance or repair centers that are knowledgeable with the type of operating system or computer.
Scheduled computer maintenance is important to guarantee that it is secure and is functioning properly, especially for businesses and organizations that bank expectantly on computer networks. Finding an adept computer and IT professional is priceless in ensuring that the actions and important data stored in the communication systems will not stolen nor leaked. Computer maintenance and assistance providers help your organization increase its productivity.

First Year Free
The first exciting bit of news is the one that has been swirling around the internet all day, and that is, for the first year of its release Windows 10 will be free to upgrade to. So if you have Windows 7 or 8 you will be able to purchase and install Windows 10 free of charge. Once it is installed you will be receiving the same support as someone who purchased it. A free OS upgrade is a pretty huge deal; normally OS will cost you a little over 100 dollars. I know a lot of people were resistant to Windows 8 based on its Metro look, but the good news is that they combined the old school feel, and the new metro look into one nice smooth UI.

Cortana
Another great little tidbit is that Cortana is going to be coming to Windows 10 as well. If you are unaware Cortana is the Microsoft version of Siri. As it stands Cortana is already a stronger version of the software than Siri, and they have gone to great lengths to make her voice more fluid and human-like. They will be docking her near the start menu and can use it for voice and non-voice related functions. It will be a fun little feature that might make life a bit easier for people.

Spartan
Microsoft has gone to great lengths to make Internet Explorer a good browser, but to be honest it is a rather looked down upon browser. People love Chrome and Firefox, but it looks like they are scrapping that project and moving over to Spartan. Spartan will be taking on the role of the default browser and is looking very solid. They have made the browser cleaner, faster, and more resistance to the average spyware and virus.

Gaming
Microsoft has gone to some great lengths to make gaming more enjoyable, including streaming the Xbox one to your Windows 10 device. That means you can play your Xbox one from your tablet, phone or PC. They are also introducing Direct X12, which they are claiming will show improvements of performance of up to 50%. It also looks like Fable Legends will be set up for cross platform play. As well as the games and improvements on Direct X12, Microsoft is going to make it easier to view and store clips of video games. There will be a default folder for it and can be quick accessed at any time. I think they made a lot of good steps for PC gamers here!

Holographic Headset
Last but not least, they showcased their holographic 3D headset. It reminds me of having Jarvis from Iron Man and Google Glass; with it you can see holographic images and doing wireless computing with it. There are no limits to what people are going to be able to do with this tool.
Microsoft covered a lot of really great information which will likely shape the future of the operating systems and computers for a long time. With Windows 7 hitting the end of its natural life and going to extended support, now is a good time to join the new OS which will likely be amazing!

This document contains information on what to do you if you are not getting any sound out of you computer speakers. These sections should be followed in order because they are written in such a manner that you may identify your issue through the process of elimination.

Desktop speakers turned down
This step may seem trivial, but problem-solving works best when you start with the basics. Verify that the volume knob on the speakers is turned up enough to produce a sound. Almost every pair of speakers with knobs will increase the volume by turning it left to right, otherwise known as clockwise.

Laptop speakers turned down
If you are using a laptop computer with no external speakers connected, make sure the volume is turned up by using controls on the keyboard. They may buttons (as shown in the image to the right), or a secondary function of another key; generally indicated with blue text and activated by holding the Fn key at the same time.

Make sure volume in the software is also turned up
An important aspect of sound on a computer with external speakers, is that it is primarily controlled by software. For example, if the volume is lowered or off in the software settings, it doesn’t matter how high the knobs on your external speakers are turned up; the speakers won’t produce sound. Therefore, users should verify the sound settings in the software are properly turned up.

Mute is on
Another common mistake is for users to accidentally press the mute key on their keyboard. To check if mute is turned on, look in the lower right-hand side of your desktop screen for a symbol resembling a speaker with a “no” sign (shown right). Speakers are not connected properly

Laptop computers
If you are troubleshooting a laptop computer, skip this step since you cannot verify the laptop speaker connections.

External desktop speakers
Sound devices connected to the computer have different cables and therefore use different ports. First, check that your speaker cable is properly connected to the sound cardon the back of the computer. As seen in the picture to the right, the sound card has multiple jacks. Speakers must be plugged into the Line Out connector, which usually indicated by an image of sound waves with an arrow pointing out. The jack itself is usually green in color. If your speakers connect through USB, plug them into any of the USB ports.

Tip
Even if your speakers have worked in the past, still check the connection since it is not uncommon for cables to be pulled out of place.
Ensure the power cable is connected to the back of the right speaker, or in some cases, the subwoofer. Most speakers have a small LED (light) indicating if the speaker is on or off. One you’ve turned the speakers on (usually by using a button or by moving the volume knob from left to right), check to see if the light is illuminated. If no LED is present, or the speakers still don’t appear to be getting power and you’ve checked the power connections, you may have a faulty power source.

Sound card does not work
Like any other hardware component in a computer, the device producing sound can fail. Make sure the computersound card works properly by connecting either another pair of speakers or a pair of headphones. If another pair of speakers or headphones also don’t work, your sound card is likely experiencing issues. See our Missing or lost sound in Windows document for troubleshooting help.

Windows speaker setup
If you are running Microsoft Windows, make sure the speaker setup is correct by following the steps below.

  • Open the Control Panel
  • Select Hardware and sound or just Sound in the Control Panel window.
  • In Windows XP and older, click Manage audio devices under Sound.
  • On the Playback tab, select your speakers and click the Configure button.
  • If the speakers still don’t work after configuring and testing them, double-click the speakers on the Playback tab to bring up Speaker Properties.
  • Verify all settings and then Test on the Advanced tab.
  • After all changes, click Apply then OK in each of the appropriate windows before closing them.

Bad speakers
Finally, if none of the recommendations above fix the problem, but connecting a different pair of speakers or set of headphones did work, the speakers are bad. It is recommended that you contact the manufacturer of the speakers or computer for a new replacement if they are still under warranty.

Why would someone want online file hosting? It allows you to do a lot of things with your files. You can store many different types of files online. It is a way to host files online and let certain people of your choosing to download them for their own use. You can have them do this via the internet or by file transfer protocol (FTP). There are many different uses for online file storage.

If you look online you will find a lot of companies that offer online file storage. You will have to pay a specified amount in order to load your files onto their site. It is a good way for developers to share their programs with other interested users on the internet. Anyone who would like to try the program can download it and try it out. Some even allow users to modify the program in order to help in its development and work out any bugs it may have. Another use for online file storage is by individual users. Let’s say that you had some very important files on your computer.

The files housed some secret information that you didn’t want to ever be seen by someone else. You knew that if your computer was destroyed or malfunctioned, you could lose the files forever. This would be catastrophic for your business or for you personally. One option that you now have is the use of online storage. You can backup these files through a secure network. No one else will be able to access the files except you. Your files will be safer if you store them online, that way when your computer goes down they will be there waiting. You can access them if you need to and when you get your pc straightened out or get a new one, you can just go to the site and get all your files back with ease. This is better than using compact disks for instance as they only have a limited shelf life and you may find they will not read when the time comes to retrieve your files. You will probably be charged according to the space your files will occupy on their server. The more files you have and the bigger they are, the more it will cost you to store them. You may also be charged for bandwidth you use which will depend on how many times you files are downloaded.

They have to charge you a fee otherwise they could not continue to provide this service as they have to pay extra fees for more storage and bandwidth use. Some websites will have the necessary tools for you to use their services. Other companies may not have these tools on their site so you may have to use additional software. You can easily learn to use this type of software, but if you have any problems, the site will give you plenty of help to solve whatever problem you may have. Online file storage can save you a lot of trouble. If you have files you need to put in a safe place, look into using online storage.

Step 1

Check your recycle bin to see if the file is still there. The Recycle Bin holds files before deleting them, thus permitting you to restore them should you change your mind. To restore a file, open the Recycle Bin, right-click on the file, then select Restore. The file will return to its original position on the hard drive.

Step 2
Stop accessing the drive. If your files cannot be found in the Recycle Bin, save or delete nothing on your computer. You will have better chances of finding the file if you don’t save anything new.

Step 3
Download program for data recovery on another computer, or another drive. Be careful not to save the program on the drive that you are trying to recover the file from. Some of the popular data recovery programs that you can get for free include Recuva, Glary Undelete, MiniTool Partition Recovery, Puran File Recovery

Step 4
Run the downloaded recovery program. Follow the basic steps.

Step 5
Be precise at what you are searching. Make sure the recovery program is searching at the disk that the file was at the time it was deleted. You can specify file type, name and date of creation.

Step 6
When the program has finished scanning, look through the result list to check if your fie is included. If you have found it, select your file and click the Restore button.

Once you nail down the problem the next step is determining if your laptop is worth repairing or if you should just replace it altogether. In order to make that call, you need to ask yourself a few questions. What’s the cost of a new laptop? How old is your current laptop? How bad is the problem? Are you still under warranty? Can your warranty be extended?

How much are the repairs?
A general rule of thumb is if the total repair costs equal more than one-third the cost of a new laptop then don’t repair. Consumer Reports say that if the repair cost is over half the cost of a new laptop then don’t repair. However, another way to look at it is to determine how different a new laptop would be compared to your current one. Does the new one you are looking to get have at least two important features that your current laptop does not? Is the new one lighter, have a better processor, better battery, more RAM, etc…?

How old is your current laptop?
If your laptop is 5+ years old then chances are repairing it isn’t worth it. If your laptop is in the 3 to 4-year range then you could go either way. This is where checking the features can help. Anything under 2 years old is a pretty good candidate for repairs.

How bad is the problem? 
If something like your main logic board is busted then repairing might not be feasible. Did the hard drive fail? If so, then you can probably get that repaired for a couple hundred dollars. Nailing down precisely what the problem is will be the best way to determine how much money you will need to spend repairing your laptop and if those repairs are worth it.

Is your laptop still under warranty?
If so then repairs should be covered depending on what they are. If your laptop is not under warranty then you should look into extending it. Some manufacturers have actually been known to extend warranties for free if it is recently expired. Other manufacturers offer the option of extending a warranty for a small fee while some credit card companies automatically double or extend a manufacturer’s warranty. This means that you may already be covered without actually knowing it. Definitely don’t spend any money on repairs until you are 100% sure that your laptop is no longer under any type of warranty.

What is the shops warranty on repairs? 
Any respectable shop should offer at least a 90-day warranty on their repairs, which means they will fix your laptop again, if necessary, during that 90-day period. If 90 days seems too short, you may be able to negotiate for a longer warranty.

How long will it take to repair your laptop? 
Some repairs take longer than others. Some shops may not be able to get your laptop fixed and returned to you in less than a week. Are you able to be without your laptop for a week or more? Can you find a replacement laptop for the time when yours is out of commission?

How are the online reviews?
Checking online reviews is the best way to validate a company. You do it for restaurants, movies, and any other thing you are looking to do so why not do it for your laptop repair shop?

Will they make a backup of your hard drive?
A lot of shops will do this without even asking, or they may perform a backup for an additional cost. However, the best thing for you to do is to backup your hard drive on your own before you take your laptop in if that’s a possibility.

Is the shop secure?
Unfortunately, some small computer repair shops are targeted by criminals. Thieves will break into these stores, knowing that there is a possibility that there are multiple computers in there ripe for the taking.

What happens if someone steals my laptop?
 I’m not entirely sure there’s a concrete answer to this question. Each shop is different. You should definitely ask the manager or owner of the shop you’re taking your laptop to though you may not get a straight answer
