Adding random access memory (RAM) to your system is the cheapest and most effective way to make it run faster.
RAM (random access memory) is put on your computer using RAM chips placed into special slots. When your computer is turned off, RAM is empty-unlike a hard disk, it can''t store data unless the RAM is powered by electricity. Step 2: RAM''s Power Source When you turn your computer on, electricity flows from the power supply to the motherboard. Because the RAM is directly attached to the motherboard, it gets electricity from the motherboard. When RAM is powered by electricity, it can store data. Step 3: RAM and Hard Disk Relationship The data is now in memory and can be used, manipulated, and altered. The altered data stays in RAM only until you issue a command to save it. When you issue a Save command, the altered data is sent back over the bus to your hard disk, and the data is stored there. When you turn your computer off, the data vanishes out of RAM, but stays permanently on your hard disk.
EDO DRAM. Extended Data Out DRAM EDO speeds are measured in nanoseconds. You can buy EDO as fast as 50ns for your personal computer main memory (you may see faster EDO DRAM on some graphics cards. EDO memory is commonly available as 72-pin SIMMs). FPM DRAM. Fast Page Mode DRAM Fast-page mode is becoming increasingly scarce, but, unless you''re running a very early system (430NX chipset or earlier) or a 486 system, you probably don''t want to get DRAM. Fast-page mode memory comes in SIMMs. RDRAM is shipped in RIMMs (RAMBUS inline memory modules). Future systems using the Intel 820 chipset and the upcoming 600MHz plus Pentium IIIs will use RAMBUS memory, but they aren''t out as of this writing. Way back in the dark ages of the PC architecture, I once owned an original Compaq portable. While the Compaq supported a whopping 640KB of RAM, it only came with 256KB. I upgraded my Compaq myself with an additional 384KB of memory by carefully inserting 27 individual 16KB RAM chips. The hunger for memory has steadily increased since then; 64MB is no longer unusual. Upgrading memory is easier, too; you no longer must painfully insert individual RAM chips.
