DDR3 SDRAM image

In computing, DDR3 SDRAM, an abbreviation for double data rate type three synchronous dynamic random access memory, is a modern type of dynamic random access memory (DRAM) with a high bandwidth ("double data rate") interface, and has been in use since 2007...

 Processors

The processor, or CPU, Central Processing Unit, "CPU" is the essential component of a computer that interprets instructions and processes data from a program.
The processing speed of a processor is still sometimes expressed in MIPS (million instructions per second) or in Megaflops (millions of floating-point operations per second) for the floating-point part, called FPU (Floating Point Unit). However, today, the processors are based on different architectures and parallelization techniques treatments that no longer allow to simply determine their performance. Specific benchmarking programs have been developed to obtain comparisons of actual program execution times.

RAM (Random Access Memory) or RWM (Read Write Memory) is the memory in which a computer places data during processing. The characteristics of this memory are:
- its access speed, this speed is essential to quickly provide the data to the processor.
- its volatility, this volatility implies that the data are lost as soon as the computer stops being supplied with electricity.
There are several types of RAM:
SDRAM or Synchronous Dynamic Random Access Memory is a particular type of RAM that has had a long career since it was used from Pentium to Pentium 4. It replaced RAM EDO in the heart of our computers .
the SDRAM synchronizes with that of the motherboard. Reading the data in synchronization with the bus of the motherboard makes it possible to avoid certain waiting times, and in particular that due to synchronization with the motherboard. The waiting cycle is thus reduced. The SDRAM can thus operate with a rate of up to 200 MHz and reduce its access time to 5 ns. In a PC, it comes in barrel with 168 pins in 64 bits and two notches.

It is essential to cool your computer. Why? Just because its different components like the graphics card, the processor, the hard drives heat up. Normal heating is safe, but overheating can lead to malfunctions (errors in calculations, bugs, unwanted restarts, etc ...), sometimes leading to deterioration of components. Different methods of cooling exist, we quote among others:
