Why Your Computer Needs Different Types Of Computer Memory?

There are many types of computer memory. If you want to upgrade your computer memory, you have to know the different types of memory. Computer memory is an internal storage area that stores data permanently or temporarily. It also affects the speed by which the computer processes the data. Today's computer has a combination of memory, and not just one type.

Computer memory has four basic types. These are Cache, RAM, Virtual and Hard Drive.

The Hard Drive memory is where you permanently store your data. It contains program files, permanent files, Internet files and files that are saved by the user. The capacity of the Hard Drive memory is measured by gigabytes. The Hard Drive memory capacity of old computers or laptops starts from 20 gigabytes. Today, most computers come with 360 gigabytes or higher.

The Virtual memory plays its role when running applications that are too large to handle by Random Access Memory or RAM. To temporarily store data, the computer's Operating System uses the Hard Drive and gives it back when needed. Virtual memory's usage of Hard Drive slows down the performance of the computer.

Cache memory stores the most frequently used processes of the computer. It has 3 grades to indicate its level. Level 1 and 2 are the most common Cache used in most computers and laptop. Level 3 Cache indicates advanced level of systems.

Level 1 Cache memory is used for most frequently used information and processes. It is the primary memory used by the processor. L2 is next in line. It is more commonly used on the motherboard. Depending on the motherboard used in the computer, the L2 can be upgraded or not. L3 is the most advanced Cache memory as it can speed up the memory.

The RAM or Random Access Memory is the most commonly used memory as every file or application that is processed in your memory needs it. Each time a data or application is requested on your computer, the processor sends the request to your RAM, which then processes and writes it back to RAM. But the data that come and go in RAM are temporarily stored. As soon as the application or program is closed, the files are deleted from RAM.

RAM has many types. These are the SDRAM, DDR, SIMM, DIMM, SODIMM, and DRAM.

The SDRAM or Synchronous DRAM retains memory and synchronizes with the timing of the computer. It does not need to refresh. It is faster and more expensive than DRAM. SDRAM's speeds are 66, 100, 133 and 266 MHZ.

DRAM or Dynamic Random Access Memory holds information for a short time and needs to be refreshed every now and then. It is measured by access time and storage capability.

SIMM is Single In-line Memory modules used to store one row of EDO or BEDO or DRAM chips. SODIMM is Small Outline Dual In-line memory module found in notebooks. It is smaller than standard DIMMs. DIMM or Dual In-line memory module contains 2 rows of DRAM, EDO or BEDO chips. DDR or Double Data Rate doubles the speed rate of data transfer.

Before you purchase the computer memory, you have to know the types of computer memory fit for your computer. Memory used in laptops and notebooks are different from memory used in desktop computer.

Reasons Why You Should Have A MicroSD Card

The HTC EVO Shift is the little brother version of the HTC EVO 4G and although it's smaller, it still provides a similar gaming experience. One of the limitations of the EVO Shift is that it only offers 512MB of internal memory and only 370MB is actually accessible to the user for gaming.

The HTC Evo Shift is a powerful and multifunctional device that can serve many purposes for the modern smartphone power user. But like its larger cousin, the HTC Evo, it’s clear that HTC designed it with a focus on delivering a top-notch gamer experience. And even though the HTC EVO Shift is not exactly on par with the HTC EVO on the gaming level, it's not that bad. HTC even has a wide range of gamer-oriented HTC Evo Shift accessories, including an extended-life HTC Evo Shift battery and a thumb-friendly HTC Evo Shift case. The Shift, however, is not perfect.

The imperfection that stands out most to gamers is the amount of memory that the HTC Evo Shift has. It has 512 MB of internal memory, but only 380 MB of that is actually accessible to the games. The rest is reserved. The HTC Evo Shift also has microSD support, up to 32 GB, and fortunately, HTC helps to overcome the limited memory by including a 2GB microSD with every HTC Evo Shift sold. But even that additional 2 GB is not enough, so in this article, we examine the benefits for gamers who upgrade that card to 4, 8, 16 or even 32 GB.

One of the main concerns with games is that they have a larger memory base than other programs. Therefore, one of the obvious benefits of a bigger microSD is the extra space available in which to install games. It's a shame that the HTC EVO Shift does not provide immediate support for this out of the box. But gamers tend to be savvier than the average smartphone user, and if they’re willing to partition the microSD card properly and, in some cases, make use of a third-party app, they can use the card to install to and run from.

One advantage of newer games is that it can be worked around to be used correctly. Some of these tricks involve microSD cards. For example, some 3D Android games will, if giving proper permission, use the microSD card as a cache. The issue with these caches is that they often have to be quite large in order for them to be effective. The included 2GB microSD card can be used but you most likely won't have any leftover space. A bigger card can provide much larger breathing room.

A nice feature of microSD cards is that they’re backward compatible, and as we move forward, the current SDHC cards are not likely to be outdated anytime soon. Any cards you purchase today will be very useful for your phone. In addition, more game developers will integrate the use of microSD into their techniques. There’s even word that HTC will include an update for the HTC Evo Shift that will allow installation to and run from support for microSD cards that won’t require rooting or third-party support.

How to increase cache memory on my laptop so i can run 3d studio max?

i have been haveing problems with my 3d max program i am currently running it on my laptop which is a Dual Core with a 512 ATI Hypermemory Graphics card it keeps running out of memory so i asked my college tutor and he said about cache memory but i forgot what he said so help!
i really wanted to know how to make it so that the program uses all my memory rather that a fraction of it

I dont think you can increase cache memory as such, but perhaps you could increase the virtual memory or possibly toss in another gig of ram

It's been ten years since Bungie gave Xbox gamers the first _Halo_ game, a
console first-person shooter that didn't feel like the weak sister to the
genre's PC alpha dogs. From that single title grew blossomed one of video
game's most successful franchises, one which reshaped what it meant to play
video games with other people. Now, Microsoft's commemorating a decade of
_Halo_ by issuing an upgraded remake of the series' first game. Is this trip
down memory lane worth your money? Let's take a gut check. More »
