Benefits Of RAM

RAM, or Random Access Memory, plays an important part in how fast your computer runs. This is because RAM stores processes and files in memory so it can be accessed quickly when needed. The more RAM you have the more you can store. The faster the RAM speed the faster these files and processes can be accessed.

When buying a notebook or a desktop computer many people do not ensure they have the right amount of RAM for their needs. The amount you need will depend greatly on what you plan to do with your new computer or even the operating system it is using. A user who plans on simply using their computer simply to write up documents, browse the internet and write emails would only need 512mb RAM, which is a small amount.

On the other hand a user that needs to perform queries on a big databases or plays RAM intensive games would need anywhere between 1GB to 2GB of RAM.

The new Vista operating system is another factor to consider when choosing the amount of RAM you need. It is recommended that computers running Vista have 1GB of RAM or more, no matter what you are doing with your computer.

As well as the size of RAM, the speed is also important. The fastest RAM currently on the market is DDR2. This format is faster than the previous DDR format. RAM speed is important just like the speed of a CPU is. The faster it runs, the more effective it is.

When choosing a computer, it is best to include that little bit larger amount of RAM that you think you will need. This will ensure that you won't underestimate the amount needed, and your computer will be future proofed

How Laser Works

Lasers are such an interesting area of modern technology that they have gained significant popularity over the past several decades. Knowing how they work is something that will fascinate anyone who has ever seen one.

The first thing that is important to understand about Light Amplification by Stimulated Emission of Radiation, or a LASER, is that they are relatively only one color of light, not multiple colors like other kinds of light. This is what allows them to produce a straight beam that does not expand nearly as much as other kinds of light after a certain amount of distance. Laser light does expand, but the beam divergence is extremely small compared to white light.

When normal white light hits an object the various colors in the light bend in different amounts. Since lasers have practically only one color, the light all bends the same amount when it hits an object. This is what allows it to keep its composure. So how do you get the light to generate only one color? It all has to do with the electrons. The "extra" energy that leaks out is what produces the given color of light. Then they produce a lot of light of the same color.

Those electrons in that material will absorb the light and shoot it right back out as one color. This can be done with various kinds of mirrors and lenses. There are all kinds of ways to energize the electrons to make a laser, and it can be very costly or not so costly, depending on the power and kind of the laser.

Lasers have so many different applications. When lasers are made, they are made with a certain application in mind. Although this article has discussed how a certain kind of laser works, it is important to note that not all lasers work the same way.
