Function of RAM and Specifications

Know Your RAM
RAM (Random Access Memory) is one of the major memories for computers. RAM location is adjacent to the processor. This is important so that data between RAM and processor can be delivered piping properly. The motherboard Diagram Sila articles refer to get a clearer picture.
RAM serves to hold the landing and data to be processed by the processor. RAM is volatile, namely mean data stored by the RAM is lost when the computer is turned off.
As an example of the usefulness of RAM, when you open this blog, your computer's RAM is filled with data describing this blog. However, It was going to disappear from the RAM if the computer is turned off (therefore we need the storage for data storage purposes).

Among the well-known that there is a market RAM is Kingston, Corsair, Hynix, Apacer and others again.

Types of RAM
EDO RAM (Enhanced Data Output RAM)
- Must be installed in pairs
- 1 notch (groove on the foot of RAM)
- Used on older machines (90s)

RAM RDRAM (Rambus Dynamic RAM)
- 232 pin
- No heat sink (typical conditioning systems)
- Must be installed in pairs
- Used on older computers (1999, 2000, ...)

RAM SDRAM (Synchronous Dynamic RAM)
- 168pin
- 2 notch
Pace: 100MHz, 133MHz
Kapasiti Maximum: 512MB

DDR RAM (Double Data Rate RAM)
- 184 pin
- A notch
Pace: 266MHz (PC2100), 333MHz (PC2700), 400MHz (PC3200)
Maximum: 1GB (no chip on the front and rear layers of RAM)

DDR II
- 240 pin
- A notch (but differed with DDR, a little hole notch to the left)
Pace: 533MHz (PC4200), 667MHz (PC5300), 800MHz (PC6400)
Maximum Capacity: 2GB

DDR III
- 240 pin
- A notch (but differed with DDR and DDR2, the hole more notch to the left again)
Pace: 1333MHz (PC10666), ...
Kapasiti Maximum: 4GB
* The term SODIMM (Small Outline Dual In-Line Memory Module) is a RAM for notebook / laptop.
* The term SIMM (Single In-line Memory Module) refers to the old RAM, EDO RAM for example having one foot of RAM our other features active (running). SIMMs have 30 pins or 72 pins. SIMM 30 pin requires 4 pieces of RAM installed on the motherboard when SIMM 72 pin requires at least 2 pieces of RAM installed on the motherboard.
* The term DIMM (Dual In-line Memory Module) refers to the more recent of SIMM RAM, DDR RAM for example where both the surface of the RAM modules that are active (running). DIMMs have 168 pins (84 x 2) and requires only a simple piece of RAM to operate.
* The term DDR (Double Data Rate SDRAM) also have characteristics similar to SDRAM, but it has 184 pins and kelajuannya more worthy than SDRAM.
