How To Test Your Random-Access Memory (RAM)?

How To Easily Test Your RAM for errors?

Random Access Memory (RAM) is computer hardware that temporarily stores data within a "working" memory area. The more working memory your system has, the more information it can process simultaneously. You can purchase additional RAM for your computer to improve capacity and performance. Do not confuse RAM with hard drive storage or other memory types. Remember that RAM is temporary storage, whilst hard drive memory retains data until you delete it. Furthermore, RAM is only used when the computer is turned on - as soon as you turn it off, the memory is erased.

How to Know if You Are Running 32-bit or 64-bit Windows?

How to Know if You Are Running 32-bit or 64-bit Windows and What's The Difference?

You may have heard that Windows can be 32-bit or 64-bit. Both operating systems are designed to utilize a processor, which is named accordingly: 32-bit Windows uses a 32-bit processor, whilst 64-bit uses a 64-bit processor. The main difference between 32-bit and 64-bit is that a 32-bit processor can only address 4 gigabytes (GB) of RAM or less. If, for example, your computer has 8GB of RAM (or more) and is running 32-bit Windows, this means that your system will be using no more than 4GB, and the remaining four (or more) GB will be unused. Only 64-bit operating systems can address more than 4GB of RAM. You can run 32-bit Windows on a 64-bit computer, but to install a 64-bit version of Windows, you need a processor that is capable of running a 64-bit version of Windows. A 64-bit operating system can handle large amounts of memory more efficiently than a 32-bit system and can be more productive when running several applications at once and switching between them frequently.

Nevertheless, there are several easy ways to rotate your video in Windows with the correct tool. In this article, we will show you how.

How to disable startup programs?

Startup programs in Windows 7 and Windows 10 are user programs that are launched automatically after Windows boots on your PC.

Sometimes, during installation of a Windows program, the user is given the option to include the program in the Startup list. Other programs may be added without such notifications. Often, various programs responsible for product updates and upgrades are added to the Startup list and continually poll update servers for new software versions. Typical examples of startup programs are Spotify, Skype, Dropbox, Microsoft OneDrive, etc. Unfortunately, Malware programs can also appear in your Startup list. It is convenient to maintain useful programs in the list that you know you will need every day, however, the more programs that reside in your Startup, the longer it takes to launch Windows.
