What is the Dell Dimension 2400 memory capacity?
The Dell Dimension 2400 is a computer that has a capacity of 1GB of RAM. It would be better to upgrade the RAM in order to get past the low virtual memory errors than can sometimes appear on the machines. The Dell Dimension is an old computer that has XP operating system installed compared to the current Windows 8.
When does thrashing occurs?
Thrashing is computer activity that makes little or no progress, usually because memory or other resources have become exhausted or too limited to perform needed operations. When this happens, a pattern typically develops in which a request is made of the operating system by a process or program, the operating system tries to find resources by taking them from some other process, which in turn makes new requests that can't be satisfied. In a virtual storage system (an operating system that manages its logical storage or memory in units called pages), thrashing is a condition in which excessive paging operations are taking place.
What IC 80386 is?
The 80386 was a third generation version of the 8086/8088 microprocessor. The second generation was the 80286, adding protected mode. The 80386 added 32 bit mode, virtual 8086 mode, and flat 32 bit protected mode.The 80386 fixed the problem of the 80286 where existing object code was not compatible in protected mode because the meaning of the segment registers changed. The 80386 allowed the operating system to run in protected mode while presenting the process with a virtual 8086 environment where the segment registers worked as before. This was a stop-gap measure that worked until the full implementation of a true 32 bit flat memory model operating system and software.
Which numbering system should not used zero?
The Roman numeral system
What is an advanced system optimizer used for?

What is virtual memory and how the system controls the situation in the absence of it?

What happens if you have no virtual memory?
If you are using a modern version of Windows (Windows 95 or latter) you will be using virtual memory. Virtual memory is NOT the pagefile and it is not an extension to physical RAM but a system that is completely integrated into the system. Applications access virtual memory exclusively, no exceptions, ever. You can not disable virtual memory. You can disable the pagefile (not recommended) but this will not disable virtual memory. The system provides a virtual environment to processes that is completely independent of how much RAM is in the system. This is an advanced system that provides many important advantages to applications and users.
How do you delete virtual memory?
Don't delete the virtual memory. It is essential to the running of your operating system.
What is deffernce between virtual and physical memory?
The difference between virtual and physical memory is that virtual memory refers to memory space while physical memory are chips like RAM. The memory space for virtual memory is made by operating system when there is insufficient physical memory.
When does the operating system creates virtual memory?
when the actual memory is full
What operating system doesn't use virtual memory?
As per my memory these OS Ferrodo, Linux, centos won't operate virtual memory.
What is the use of virtual memory?
Virtual memory is used to increase the size of working memory in the system main memory by using the locations in secondary storage such as harddisk.
The salesperson offers you a one time special 10mb of virtual memory for 100 Are you buying?
The salesperson obviously hasn't got a clue what virtual memory is - or you misunderstood him. Virtual memory is a system that is integral to the computer system, not something that can be added.
How does one troubleshoot a problem with windows virtual memory minimum being too low?
If a person is getting a message that says they are running low on virtual memory from their pc, it usually means that Windows isn't managing the memory correctly. If the virtual memory minimum is too low, then a person can go into the system and edit the amount of virtual memory manually which should fix the problem.
Does freeing up memory improve computer performance?
Computers operate best when they have "system memory" free and are not relying on virtual memory (which uses a hard drive as additional system memory). If you have a system with 1GB of installed system memory, and you are using 1.25GB of allocated memory, then freeing up 0.25GB of used system memory would improve performance by reducing virtual memory usage. Conversely, if you have 2.0GB of installed memory, and you are using 1.25GB of allocated memory, then freeing 0.25GB of used memory would have no appreciable effect since virtual memory is not being used by the system. Final answer: If you are using virtual memory, then freeing enough memory to eliminate the virtual memory usage will improve performance, but freeing up more than that amount will have no appreciable effect.
How much space is reserved for virtual memory on different computers?
The space reserved for virtual memory varies on different computers. It depends on the operating system in use and how much system memory is available.
What is the difference between swap and virtual memory?
Swap slices are used as virtual memory storage areas when the system does not have enough physical memory to handle current processes. The virtual memory system maps physical copies of files on disk to virtual addresses in memory. Physical memory pages which contain the data for these mappings can be backed by regular files in the file system, or by swap space. If the memory is backed by swap space it is referred to as anonymous memory because there is no identity assigned to the disk space backing the memory.
