In cleaning the computer’s RAM or Random Access Memory is easy and can be done in a matter of few minutes. First, you open your notepad and type mystring=(80000000). After typing the code, choose save file as at the file menu and save the code as ram.vbs as its file name and close the notepad. The file will be saved at the desktop and you need two double left click the new RAM cleaner icon to clean the RAM and your Ram is already clean. In saving the code, you can also change its name. Left click on the RAM cleaner icon then type the new name of the icon then press enter.

What is the better Gaming CPU?
What is the better gaming CPU? Is it the dual core CPU or Quad Core CPU? If you want older versions, current, or not aiming on the latest games for the next upcoming year then dual core CPU is better to use than Quad Core CPU. If you want the updated games or seek the new released games, then quad core CPU is the suitable processor for you since most of these games use all four cores and if your computer is not just for gaming but for other applications then quad core is better to use than dual core.

How to format your memory stick
Formatting a memory stick is also important to know so if this will be necessary then you’ll have the idea on how to do it. First, insert the memory stick at the device for example, a 16GB for psp. Second, go to the settings of psp and choose system settings. After choosing system settings find the “format memory stick” command and choose that command. It will let you decide if you really want to format your memory stick and if you press yes, it will again ask you if you want to continue and delete all the data in your memory stick. Choose yes and wait until it completes its formatting process.

Why CPUs Need Heat Sinks?
Heat sinks are components that are responsible for transferring heat from a solid material to air or liquid medium. They increase the contact surface area to make heat transfer faster.
Modern computers have CPUs as their heart that processes all the data. Processors become hot very quickly but require cooling to function properly. This is what the heat sinks are for.
Computer h
eat sinks are attached to the processors to collect heat from them and transfer the collected heat to air or liquid media. Fans or thermal cooling solutions are attached to the heat sinks to take the heat away from them so they can provide necessary cooling to the processor.

Is DDR3 faster than DDR2?
DDR2 and DDR3 are the memories of the motherboard. Is ddr3 faster than ddr2? The answer is yes but not all the time and it still has its disadvantages too. It’s faster and has more bandwidth and produces less heat but when dealing on the price of ddr3, it’s two to three times more expensive than ddr2 memory especially when choosing a 4GB kit. Ddr2 memory has very tight timings therefore, even at its lowest range of speed, it can still outperform ddr3 memory to its highest speed. Bandwidth and memory latency are the factors that affect the speed of performance by both memories.

DDR3 SDRAM and its advantages over previous versions
DDR in DDR3 stands for Double Data Rate. It is the latest memory standard for hispeed SDRAM that we use in our computers. DDR3 is a improved version of DDR2 in many aspects. DDR3 Ram is a type of DRAM. DDR3 shows a lesser power consumption of 30 percent and also a lower operating voltage when compared to DDR2.
Lesser power consumption means less amount of heat generated. So, the cooling needs of DDR3 are less than DDR2. DDR3 Ram is not forward or backward compitable with any type of other RAM as the operating voltages, clock speeds, timing and several other factors.
DDR3 memory has a high bandwidth interface. In addition to all these advantages, DDR3 memory type also provides the facility of having up to 8 Gigabites of memory on board. DDR3 RAM modules have different notch positions to DDR2 to prevent accidental insertion of DDR3 memory in to DDR2 slots.

Microprocessor and its significance
Microprocessors are devices which accept digital information as input and process it according to the instructions stored on its memory and produce the output. It is an example of sequential digital logic system.Microprocessors operate on numbers and symbols represented in the binary numeral system. The latest CPUs like intels i3, i5 and i7 are also microprocessors.
The first cpu was developed by Intel and was called Intel 4004. Microprocessors are generally used in personal computers, mobile phones and other devices like autonomous robotics. They are now used almost in every electronic device where processing is necessary like media players, mp3 players, optical disk players, network devices and many others.
Some of the first units are 8-bit designs. Then 12-bit microprocessors were developed. 16-bit and 32-bit were developed which were quite popular due to their computing ability. The latest version however is a 64-bit which is used in high speed computers.
Smart cards and their uses
Smart cards
are pocket sized cards with integrated circuits on them. They may generally contain volatile memory or microprocessor components. In large scale industries and organisations, smart cards can provide high security authentication. The card is generally made of plastic and has external metallic strips for contact interface.
A typical Smart card may have the size of a credit card. It can have different types of functionality according to its use. For instance, if the card is used for a security purpose, it may have a secure cryptographic microprocessor for authentication. Additionally, a smart card may also have the functionality to interact with atm machines or other vending machines.
Smart cards can provide identification, authentication, data storage and application processing capabilities. There are other types of smart cards that do not require contact. These smart cards function through radio signals.

ROM and its role in computer systems
ROM stands for Read only memory. ROM devices are usually those memory modules which have been fabricated with data permanently. But in most modern ROMs the data stored can be modified slowly and is difficult when compared to other memories.
So, ROM chips are used in places where there is a very little need for the modification of the data stored. ROM is mostly used in the development of firmware memory modules as firmware does not need frequent updates.
Floppy, CDs and DVDs are also a type of ROM although erasable CDs and DVDs exist. But to modify data in a rewritable CD or DVD, the disk should be completely erased and then modified unlike Hard Drives in which the data can be modified without having to erase the entire content. The erasable ROM devices are in their highest form with the NAND flash memory which is being used as a storage substitute in many applications.

Graphics Cards – How Much Memory Do They Need?
When advertising, numbers always demonstrate the idea of improvement in a very simple and understandable way. Like, version 2.0 is better than version 1.0 and 4GB RAM is better than 3GB. This is because more is better and it’s a truth that is accepted throughout the universe.
But the real world is not that simple. Graphics cards
manufacturers use the RAM as a marketing tool. They put gigabytes of memory in a card that has too low a processing power to even use that amount of memory. These GPUs don’t have the necessary power to run games at resolutions and detail levels that would require such huge amount of RAM. So, a low end card doesn’t need gigs of memory when it can not even use it. High end cards have proper power that is needed to run high configuration games and they need a large amount of RAM to do so.

Types of Computer Memories
We have come a long way from the days when heavy tape drives were used to store information to hand held little devices available today. Computer memory is nothing but the collection of data on physical devices in a digital format i:e 0's and 1's.
To classify memory, there are two types broadly, one is volatile and the other is non volatile. As their name suggests, volatile memory can store information only till it is supplied with electric energy and non volatile memory can retain the information even after the supply is disconnected.
In present day computers, RAM is a volatile but high speed memory, while Hard Drives are non volatile but low speed memory. There are many types of volatile and non volatile memories that have been developed. Among them, Different types of RAM like SDRAM, DDR, DDR2, DDR3 etc stand for volatile and flash drives, hard disks and optical storage devices are a few types that come under the non volatile category.
