Virtual memory is a memory management technique where secondary memory can be used as if it were a part of the main memory (RAM). When the RAM is not sufficient to hold all the running programs, the operating system moves some data from the RAM to a space on the hard disk called the swap space or page file, creating 'virtual memory'. This allows for larger programs to run and for multitasking to occur more smoothly. However, because accessing the hard drive is slower than accessing RAM, relying too heavily on virtual memory can cause the system to run slower, impacting performance.
