RAM - The Key To Speed

We are all familiar with RAM (Random Access Memory) as it is an important and integral part of the computer that we use in your home, office and anywhere else. The question is why is it important and why do the computers require RAM? The RAM is a particular type of volatile memory, which is a lot faster than the hard drive but a lot slower than the processor. The components used to make random access memory (RAM) are the main reasons behind it. In computers, we needed a memory which would not be very costly but at the same time, would also be relatively fast for the CPU to interact with. RAM is such a memory. Want to learn more about RAM? Get some technical support on this.

The primary memory or the RAM has undergone several changes as per as technology is concerned. We measure its speed in terms of frequency it uses or the mega hertz. The frequency should be compatible with what the processor can take care of. That means, the speed of the RAM cannot be more than that of the processor. The motherboard should be able to support the RAM frequency and the type of RAM (SD RAM or DDR) as well. The operating system should also be able to support the amount of RAM. The performance of your computer will depend upon all these factors. All these should be recommended by a trained technician.

Although higher RAM leads to better performance of your computer, but at the same time, one should not always ask for more and more RAM without knowing his/her requirement. So, how much RAM you should have in your computer? It entirely depends upon the configuration of your computer as well as the software that you would have in it. It is necessary to choose it correctly if you want to ward off any RAM problem.

Every software needs a minimum amount of RAM load, however it is always good to have more than the required amount of RAM for better performance. If you only do day to day work like checking emails and are not really into playing high-end games, then you may not require too much of RAM and you can easily save a few bucks by not going for more RAM. But if you have some software loaded into your computer that requires higher resources, then higher RAM is needed as well. A good RAM with some “wide roads” to fetch the traffic from the RAM to the CPU (through the motherboard) and vice versa adds to the speed. That “wide roads” is called the FSB or the Front Side Bus of the mother board. It often proves to be a bottle-neck (if not adequate) in the performance in spite of the presence of a faster RAM.

How does an external hard drive work

While working with computers, everyone needs to back up his/her data from time to time. Now, whenever it comes to backing up the entire data of a computer, most people prefer to go for an external hard drive. It is so because transferring the files and folders from your computer to such a drive is an easy process. The only thing that you need to do is, just drag and drop the data onto the drive. However, there is a very thorough procedure behind this process which you must consider if you really wish to make the most out of your investment.

The components of an external hard drive: Before considering the functioning of an external hard drive, it is crucial to get familiar with components which are the same for all sorts of external drives. Basically, such a hard drive possesses an aluminum coating similar to that of an internal hard disk. If this layer or coating is damaged, then your hard drive turns into a useless metal square. Inside this coating a chip that consists of several small circuits is located which helps in storing the data. Apart from this, a motor is also fitted inside this layer which acts as a cooling fan for the hard drive. Finally a head is attached over the surface of the disk that works like a record.

Now, when you have come to know the components of a typical external hard drive, it's time to consider its working mechanism. Basically, all the information from a computer to an external disk is transferred through a USB port. However, in some advanced computers it may be Firewire. Both of these ports make an external hard drive an addition to the storage capacity of the computer. In order to make this drive communicate with your computer, you need to install a driver which is usually provided with it. But, in most cases you don't need this driver as the operating system itself recognizes your external hard drive as a mass storage device.

Once the drive is identified by the computer, you can easily drag and drop the files into it. Most external hard disks are integrated with both the ROM and RAM storage mechanics, which enables them not only to store the information but also retrieve it for further use. Remaining components of the drive perform the tasks such as establishing and maintaining the connection between computer and disk, operating the drive etc. Here the cooling fan reduces the temperature of the external hard drive so that it may not overheat.

After the connection is established, the transfer of information occurs in both directions, from external hard drive to computer and vice versa. The USB cord is used to carry the current while the drive is connected to the computer. That's why you must eject the drive from computer and then physically remove it. Because pulling out the drive directly from the USB hub may harm either the computer or external hard drive or both.
