There are actually two type of storage found in the computer. This is referred to as computer memory. The Volatile memory should need to refresh in order to retain it. There is also what you call static memory which is permanent storage when it retains information even after the computer was shut down. Random Access Memory is considered as a volatile memory that can be erased when the computer is turn off. There are actually program instructions and date being help in RAM so it can be accessed and save more quickly in permanent storage. The programs, files and data being used are contained here.

The amount of ram is dependent on the operating system that you are using. This includes basic computer functions, output display in the screen, disk drive control and other devices. You can select the computer programs that you intend to run. When you actually turn on the pc, the operating system is actually loaded to the RAM. This includes utilities that are used in operations. Programs and data are load to the memory that is left. 2mb is a device that is enough for DOS programs. For windows, 4MB to 8MB is required.

Aside from the operating system that is required, applications would also play important factors. More memory is needed for real time video and heavy graphics. There are machines sold that is enough for general computer. RAM is considered practical because of memory handling, reducing access time and lower cost. For programmers, they need a higher RAM.
In buying static memory, there is a need to buy a computer with hard drive. This is the essence of the computer. You need to know how big the storage unit is. 250mb is popular however new computers today are in 500 to 1000MB.

Permanent files are not moved but rather copied. If the computer shuts down during processing, the programs are saved. The data would only be lost if you didn’t save it. For mac users, there is enough of computer memory to run it.

Computer memory cards are an essential part of your computer system. Without this, they can’t be able to function well. Usually this is a part that determines how fast the computer should be. Typically when you purchase one, it goes with a battery. This can provide the power in order to properly work. You can actually retain information for memory and operations like input and output. This is a tool so that you can expand the memory to store data. The good news is that these memory cards only need small electricity for it to work. It has a battery that run this can last for years.

If you detached this into the main computer, it has a tendency to actually drain. It is drawing current to computer memory for support. When this hooked to the actually computer, the low voltage coming from it can be detected as low battery. There are some computers that can alert you in these cases. However not all of them can alert the user of the condition. Computer cards are actually very small so its battery is also this size. This can definitely result to low or limited battery capacity. Because of this, a typical one can’t alert the user for its low battery condition. It can go unnoticed if the card is not hooked to the main computer.

The computer is equipped with connectors, card slots and computer cards that can be replaced. With these tools, you can easily secure the card. There is an anchor found in the connectors. There is also a tie being wrapped in the mounted computer wrap. They have a connector at the end to secure the card in the slot. Its clip has prongs with hooks so you can place them at the side. The anchor has hooks and it is connected at the opposite sides of connectors. You can tie both sides at its end.

The card holder maybe used for electric device in which you can plug in cards if there is a problem with it. You can do this when there is a physical dislodgement in the card. There are many computer cards that are manufactured under the standards of Personal Computer Memory Card International Association. It is best to take time when investing in computer memory card. Make sure that they are coming from a good brand that you can trust.

If you own a cheap computer memory chances are, you need to upgrade this constantly. If you want to upgrade the ram of your netbook to about 2GB, this is actually an easy thing to do. The internet can be your best resource on this. There are some forums that you can join this discusses this topic. You can also read some how to guides that you can follow. There are also some reviews that you can read if you want ideas about this matter. Take note that this thing could probably make you confused than ever. There are some terms like cl, 667 or 800MHz and non-ECC that you might now understand. It would probably be hard to select the type of memory that one can actually need. Although the numbers are essential, it is best to check if it is compatible with your netbook.

The most popular and the best rated ones found in the market is Crucial 2GB stick. It is a product with all the things that you need. It is best that you know something netbooks. Most of the modern ones being sold have an atom processor inside. This tool has speed of up to 667MHz. This is actually how fast the memory has to travel for the processor to make use of it. Even if you get a memory of about 800MHz, this wouldn’t be able to help in anything. There are some that can’t accept this. It is best to make sure that the ram is non-ecc and 200 pin SO-DIMM. This would certainly fit any netbook, pc and laptop.

You should need to consider the CL, or cs latency. This can determine how fast the memory can operate. The lower it is the better. There are actually two kinds of crucial ram sold in the market – 800MHz with a cl=6 and 667MHz with a cl=5. The price of these is only couple of dollars apart. There are people who might think that 800MHz is faster but it is not true. It is best to select the one with smaller latency.

It is easy to install this, after purchasing turn off the compute and remove battery. There is an access door leading to memory. It is best to remove it. Push it so that it would pop out. Replace 1 gb memory stick to 2gb. See to it that the pins are lined up. The stick should be at the bottom. Push it until you hear a click. Replace the cover and insert that battery. If your OS is xp, it would detect it right away and there are no other necessary steps. Make sure that the properties recognize this new memory installed.

Various sectors of the personal computer have developed drastically in terms of capabilities and performance.

Computer memory or popularly known as Random Access Memory (RAM) has increases massively in performance throughout the years.

A popular statement made in the eighties by Bill gates explaining that no one would ever require more than 640KB of memory. Although that has gone by for years and with sophisticated performance computer systems at times containing over 1GB of memory.

There are several benefits that can be seen with more memory:
• Programs operate quicker
• Reduced waiting time for program loading
• Several programs can operate at the same time
• Increased total computer speed

Double Data Rate (DDR) memory is the fundamental of the user market. It has become quite sophisticated because of increased public demand and now can be purchased at a reasonable price.

Currently, computers are not usually manufactured with less than 256MB of memory. My computer after just installing Windows 2000 (no, I have not installed Windows XP yet) requires approximately 80MB of memory. That is minimally, who no extra programs or any other applications installed. After installing the entire graphics drivers, Internet connection application for ADSL, virus protection program, and firewall, it requires approximately 160MB of overall memory.

Based on my initial experience, 256MB will suffice, but after it becomes rapidly packed when operating several programs, Windows goes back to employing the hard drive for memory. It is a method to fake more memory, by employing the hard drive as an impermanent storage. Basically, 512MB is suitable for my needs, but if you operate several programs or memory intensive programs, 768MB or even 1GB is recommended.

But is only factor is memory size?

An evenly essential aspect is the memory speed which is measured in megahertz (MHz). Almost all systems utilize 400MHz DDR memory. This would be a very calculated assumption with almost any processor you may own. 400MHz is also the most usual to purchase, there is not to many RAM slower than that left to purchase.

Memory produced by a respectable manufacturer will guarantee that you do not have problems with it and will also offer specific amount of overclocking if you are interested in it. Even more recommended would be to purchase faster memory; it just runs down at the computer speed, even if it is manufactured for more.

One other factor of memory has come into the fold, becoming highlighted most entirely by the passionate overclocking crowd and that is latency.

Basically, memory is a bank or table of places where data and information can be stored. In order to receive the exact columns and rows specific things must be activated within the memory. In conclusion latency refers to the length it requires to be able to access another section of memory.

The shorter time it requires, the faster it is.
Low latency is quite expensive with 512MB of high grade memory priced more than some types of processors.

Though does it really benefit you?
If you are a fan of high-speed 3D games then there is definitely a difference. For the standard user, there might not be too much difference. It is yet worth it though to maintain latency in mind when purchasing. I would definitely select a lower latency model when purchasing.

Dual channel memory is one other current addition to memory technology. What this does is it places memory into pairs, thus the two pairs jointly can enhance the speed and performance of the memory of up to 10%. Though it has to be supported by the motherboard and the memory must be the dual channel type. Dual channel will operate even when not in a pair, but standard memory will not have any benefits when paired together.

Lastly, DDR2 is a brand new addition offered for Intel systems. It possesses 240 pins (the tiny copper strips at the base which plugs into a slot) compared to DDR memory that has 184 pins. Based on this, both of them are totally incompatible. DDR2 is manufactured to be in pairs though they do not require to be, but they all posses dual channel capability. Just Intel processors with LGA775 socket type utilize this type of memory, but it is quite quicker.

Thus, whenever searching for more memory, try to consider the following factors:
• Do you require DDR or DDR2 (LGA775 systems)
• What speed would you require? Frequently 400MHz (named PC3200) or quicker?
• 256MB minimum, preferably 512 or up to 1GB
• Dual channel pairs. Do you require them and does your personal computer support and facilitate them?
• Latency, the lower the better, but is not necessarily essential. CAS of 3 is normal.

In this rapid era, almost everybody require quicker access of information, thus the DDR-II RAM is a landmark. It has features that makes it much more efficient compared to DDR-I RAM. Physically, the appearance of DDR-II is unlike DDR-I due to the number of pins (Golden fingers), the DDR-II has 240 pins whereas the DDR-I has 184 pins. Thus we cannot install DDR-II RAM in personal computers where DDR-II is not applicable and suitable. Based on sped the DDR-II RAM can reach 400 MHZ at its lowest level whereas this level is the highest for DDR-I. The maximum speed for DDR-II is 800 MHZ. Thus we can state that upgrading your computer system with DDR-II will result in a more efficient and quicker performance.

The DDR-II RAM can operate at quicker speeds and also can adapt with higher data bandwidth thus allowing us to access the Internet faster. Also, the DDR-II needs less power, which makes it very energy efficient and if we use the computer for long periods of time, this will allow us to save money on our energy bill. Compared to the DDR-I RAM the DDR-II RAM stays cool for a longer period of time due to its enhancements of thermal performance.

If you are considering buying RAM for your personal computer, initially you must review your manufacturers technical guidelines, as your new RAM must be suitable and compatible to your PC. If you purchase the incorrect DDR where it is DDR-I or DDR-II, it will end various functions of RAM and decrease the speed of your computer.

Do not personally install memory by yourself; this will cause your computer’s warranty to become void so go to a sale and service center of a respectable personal computer company with your memory. There you can meet and consult with technicians to assist you in upgrading your computer with your preferred RAM.

By installing a DDR-II RAM, we can enjoy increased performance rate for our applications, quicker program downloads and so on. We can without difficulty swap between programs and can run several programs at a time. It will increase the speed of our personal computer and since it performs at a quicker rate, it will also perform more efficiently.
