+Memory Information + + + +&Mike.McBride; + + + + + +2002-02-13 +3.00.00 + + +KDE +KControl +memory +system information + + + + +Memory Information + +This module displays the current memory usage. It is updated +constantly, and can be very useful for pinpointing bottlenecks when certain +applications are executed. + + +Memory Types + +The first thing you must understand, is there are two types of +memory, available to the operating system and the programs +that run within it. + +The first type, is called physical memory. This is the memory located +within the memory chips, within your computer. This is the +RAM (for Random Access Memory) you bought when you +purchased your computer. + +The second type of memory, is called virtual or swap memory. This +block of memory, is actually space on the hard drive. The operating +system reserves a space on the hard drive for swap space. +The operating system can use this virtual memory (or swap space), if it +runs out of physical memory. The reason this is called +swap memory, is the operating system takes some data that +it doesn't think you will want for a while, and saves that to disk in +this reserved space. The operating system then loads the new data you +need right now. It has swapped the not needed data, for +the data you need right now. Virtual or swap memory is not as fast as +physical memory, so operating systems try to keep data (especially often +used data), in the physical memory. + +The total memory, is the combined total of physical memory and +virtual memory. + + + + +Memory Information Module + +This window is divided into a top and bottom section + +The top section shows you the total physical memory, total free + physical memory, shared memory, and buffered memory. + +All four values are represented as the total number of bytes, and + as the number of megabytes (1 megabyte = slightly more than 1,000,000 + bytes) + +The bottom section shows you three graphs: + + +Total Memory (this is the combination of physical and virtual memory). +Physical Memory +Virtual memory, or Swap Space. + + +The green areas are free, and the red areas are used. + +The exact values of each type of memory are not critical, and + they change regularly. When you evaluate this page, look at + trends. + +Does your computer have plenty of free space (green areas)? If + not, you can increase the swap size or increase the physical + memory. + +Also, if your computer seems sluggish: is your physical memory + full, and does the hard drive always seem to be running? This suggests + that you do not have enough physical memory, and your computer is + relying on the slower virtual memory for commonly used data. Increasing + your physical memory will improve the responsiveness of your + computer. + + + + + +
