A virtual address list is necessary for computers to locate and access virtual memory, and to manage memory partitions. It can also be used for virtual networks. The list registers the sources of virtual memory and details how memory is being used.
A virtual address is similar to a home or work address, except that it points to the physical location of the virtual memory. One reason a virtual address is needed is because virtual memory acts like physical memory, but it isn’t, and the computer needs to know where the memory can be accessed. Another reason is that the address list shows how memory is being used, which makes managing a memory partition easier. This can also be used to register network addresses on a virtual network, because there are no other connections to associate computers with.
Many computers have virtual memory that increases the overall amount of memory in the computer and comes from physical hardware such as the central processing unit (CPU), even if it doesn’t come from a physical memory chip. To facilitate access, the virtual address list registers the sources of virtual memory. By following this list, the computer can easily find the physical location of the memory, which makes processing easier.
While virtual memory acts like physical memory, the physical area that simulates memory must be accessed in order to use virtual memory. This makes a virtual address list necessary if the computer is to know where to find memory. If the computer can’t find the physical address, the virtual memory is useless, because nothing can be stored there.
Memory has different access levels, and a virtual address list details how the memory is currently being used. Most of the memory in a computer is public, which means anything can be stored in the memory space, allowing the computer to easily process and store them. If the memory is private or is being used for a partition, the address list will ensure that the computer does not use this memory except for needs that directly reflect the purpose of the partition. For example, if a partition is created for job files, only job files can be saved to the partition.
The virtual address list is normally used for virtual memory, but it can also be used for a virtual network. This type of network is traditionally not connected with wires or through normal wireless connections but through virtual links that link computers together. In this case, the address list represents the physical location of each computer on the network, so that the computers can stay connected.
