The RAM is the memory of computers that are the data used during normal use of software. The more great Ram memory of a computer and much more will be fast software installed, which should not store the temporary data on the hard drive. Being a volatile memory the contents of the Ram is temporary and reset for each new turn on your computer.
What Ram for your computer?
Fundamental choose the Ram depends on will of the computer. The choice side technology out there, a computer media power has a memory of 128 MB Ram (Mega Bytes = one million characters) to 256 MB. There are still configurations available with 512 MB or higher. For normal use of Office or other applications commonly used (Internet, email, etc.) is sufficient focus on memories from 256 MB RAM, now considered the minimum needed for modern computers. For more demanding activities such as photo editing and video games is advisable to invest in superior solutions, buying directly from a RAM 512 MB or 1 GB (1024 MB) or on other words you need to add computer RAM (if you are IMAC addict, sure you need to add IMAC memory too)
The amount of memory choice for your computer is very important because the RAM choice will depend most of the performance of the system.
Today, the memories are DIMM RAM type DDR (Double Data Rate). The speed of RAM currently on the market partly by 333 MHz (DDR PC2700 Memory) to 466 (PC3700). The memories modern use the same bus for data transfer in both ways. A big step forward compared to the old RAM "one-way alternating" (eg: SDRAM) in trade a few years ago.
To understand the importances of observing enough RAM access times. The speed of memory varies from 6 ns for the RAM to 333 MHz (PC2700) to 4.5 ns for the RAM to 466 MHz (PC3700). Obviously, a faster equal’s faster performance in software and less waiting time for users of computers.
For the more demanding in terms of performance are also available memory cards type of DDR RAM at speeds of 550 MHz with no loss of stability of calculation and access times reduced to just 3.5 ns, or RAM memories with a great storage capacity, up to 2 GB (2048), particularly suitable for computer graphics and photo professional.
The price is in constant change. It ranges from 30-40 euros for solutions RAM medium and no-brand to 150-200 euros for complex solutions and more efficient. Between the two extremes there is a wide choice term for combining performance with your portfolio.
