What is the difference between a 32-bit and 64-bit CPU?

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 early1990s. 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 legacyprogram. 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.

YouTube keyboard shortcuts

YouTube has several keyboard shortcuts that can be used while watching YouTube. Keyboard shortcuts like pressing the spacebar to play and pause or using the arrow keys to fast forward and rewind can make a big difference while on YouTube.

• See our YouTube keyboard shortcuts list for a full listing.

Share a video at any point

Not everyone wants to watch a full video, link to the exact location you found most entertaining instead of making your friends or family watch the full video. To do this get to the location you want and pause the video. Once paused right-click the video and select Get video URL at current time and then copy the link created.

Alternatively you can manually add the time by adding "#t=XXmXXs" at the end of the URL, where XXm is the minutes, and XXs is the seconds into the video you want to start. For example:

https://www.youtube.com/watch?v=MKVWBUwoV4o

would become

https://www.youtube.com/watch?v=MKVWBUwoV4o#t=33s

to link to the video 33 seconds into the video. If you wanted to link 4 minutes and 20 seconds into a video add #t4m20s to the end of the URL. Alternatively you can use only seconds, so 4 * 60 (seconds in a minute) = 240 + 20 = 260 seconds for 4 minutes and 20 seconds into the video.

Find out what is popular on YouTube

YouTube can be a great place to find the most popular videos because of its popularity. Visit the Popular on YouTube to find the most recent popular videos, recently released music videos, top cute videos, latest trailers, events, and much more.

Add videos to Watch Later

Sometimes you just do not have the time to watch a video or maybe you just do not feel like watching an hour long video at this time. In the bottom right corner of every video is a Watch Later button that will add the video to your watch later list. Once you are ready to watch the video or if you saved a video to share with someone else you can find the video in your Watch Later Playlist.

Bonus Tip: Each of the thumbnails of videos on YouTube also shows the Watch Later icon when hovering over the thumbnail of the video.

Take advantage of search filters

YouTube usually does a great job giving you search results but is not always perfect. Take full advantage of their search filters by clicking the Filters button to get a list like that shown below. In the filters list you can refine the searches to when the video wasuploaded, length of the video, view count, and features like HD (High definition) and 3D.

Watch live videos on YouTube

YouTube is not just pre-recorded uploaded videos they now also feature YouTube Live, which has live events, sports, news, gaming, music, education, and much more.

Take full advantage of YouTube tools

Not many people know that YouTube also has several helpful YouTube Tools that can help extremely helpful when creating new content. For example, the YouTube editor allows you to edit uploaded videos, create videos, and adjust settings like the brightness and contrast, pan and zoom, stabilize, slow motion, and rotation. Other tools include a Slideshow creator, YouTube capture, Captions, Audio Library, and YouTube Analytics.

Bypass regional restrictions and other blocks

Some videos may have restrictions that prevent them from playing on a certain device, playing in a certain region, or other restrictions that prevent you from playing the video. You can bypass some of these restrictions by changing how the URL is entered into your address bar.

For example, copy the id of the video (shown in red) in the URL.

https://www.youtube.com/watch/?v=dD40VXFkusw

Once the id of the video has been copied erase everything after the .com/ and add "v/<id>" where id is what was copied earlier. Once this is done your URL should resemble the example shown below.

https://www.youtube.com/v/dD40VXFkusw

Loading this URL opens the video in a full screen, but because of how it is loaded many of the restrictions YouTube may have on the video are ignored.

Set the default video quality

Watch all videos at the highest quality by adjusting your settings to use the best quality. To adjust your settings click on your profile icon in the top-right corner of the window and click the YouTube Gear settings icon as shown below. In the YouTube Account Settings, select Playback and then select "Always choose the best quality for my connection and player size." If you have a slow Internet connection or YouTube videos frequently need to buffer, select the "I have a slow connection. Never play higher-quality video" option.

Alternative ways to watch YouTube

There are dozens of ways to watch YouTube today. Most Smart TVs already have an app that allows you to watch YouTube videos on your TV using your remote. For those who do not have Smart TV or have a Smart TV but do not like the interface (it is not easy typing on a remote), there are also other solutions.

Our current favorite method of watching YouTube on the TV is using the Google Chromecast. The Chromecast allows you or anyone else with a smartphone or computer to stream YouTube videos to your TV with a click of a button.
