The obvious difference between a desktop and a laptop is the size which correlates with everything that makes the gadget. The circuitry is smaller and so are the vital components.
The desktop utilizes a different memory module that is, the Random Access Memory and the type of modules. Desktop uses a Dual Inline Memory Module. The central processing unit accesses the information stored on DIMM and if it is accessed at a faster speed and is more readily available, the unit will run faster.
The DIMM is used for the upgrading of random access memory and is one of the easiest and the cheapest ways to increase the storage. DIMM uses a 64 bit data parts. The working of the desktop memory is thus.
The CPU initially stores vital information in a temporary storage or cache. Then, it would search through the long term permanent storage after looking at this storage. If the desktop has to work faster, it needs more temporary folder to access information. The desktop memory is all about random access memory, read only memory, operating system and the basic input output system.
But, while replacing the DIMM, the storage capacity has to be added, by counting the number of chips. The memory upgrade of desktop is quite simple, it simply needs to replace the memory module with faster processing speed or alternatively, stack the chips and the mother boards. This would help utilize one slot and build up more memory. Chips can be purchased from discount computer hardware store or a staff member from service department can upgrade for a small fee.
