User space is where user applications and programs are stored in a computer’s virtual memory, while kernel space is used by the operating system’s internal processes. Users can modify and delete data in user space, which is governed by the kernels to ensure stability. RAM is the most common form of computer storage, and data in user space can be temporary or long-term. Upgrading memory or using external drives can increase storage space.
User space is a part of a computer’s operating system (OS) virtual memory. All user applications, work and programs are stored in the computer’s user space. Virtual memory used by operating system device drivers, kernels, and kernel extensions is stored in kernel space.
The user directly influences what is stored in user space and how it is used. Kernel space is used by internal operating system processes and is usually unaffected by users. Users have the possibility to modify and delete the data contained in the user space.
The amount of space available depends on the age and quality of your computer. As a general rule, companies have increased the amount of user space available with each new model. Those increases have gone hand in hand with developments in processors and graphics cards. Bigger and better software packages and games required an increase in the amount of user space. An increase in data space does not equate to an improvement in quality and performance just as a larger warehouse does not make the products contained within better.
The most common form of computer storage is random access memory or RAM. This is a form of semiconductor storage and is also sometimes called dynamic-RAM or DRAM. RAM was first developed in the 1950s and differed from other storage methods in that it could access information in any order, whereas earlier modules had a predetermined order of data.
Data stored in user space can be further divided into temporary storage and long-term storage. Temporary files are lost when the application is closed or when the power is turned off. These files are quick to execute and access. Long-term storage offers more capacity, but access is slower.
The data contained within a user space, as with kernel space, is governed by the kernels. These ensure that two data or two programs do not interfere with each other. Kernel programs connect the central processing unit (CPU), data stores and devices. This way, the operating system remains secure and stable.
Users can add more storage space to a computer in two ways. The first is to upgrade the computer by inserting additional memory. This is a risky process because computers can be damaged easily, especially by static electricity. The second option is to connect flash drives such as Universal Serial Bus (USB) memory sticks. The data can run on the computer’s operating system, but stored on a separate drive to minimize user storage space.
