Add more RAM to boost your World of Warcraft Cataclysm experience
Add more RAM to boost your World of Warcraft Cataclysm experience
The millions of virtual citizens of Blizzard's hugely popular MMORPG, World of Warcraft, celebrated the recent launch of the game's latest expansion pack — World of Warcraft: Cataclysm. Those of the game's 12 million-plus subscribers who meet only the minimum RAM required specifications of the new title, however, might want to look into upgrading their RAM and hard drives in order to maximize their Azeroth experience.
The minimum requirements for Cataclysm are not extreme compared to most games, but they are a jump from the last expansion pack, 2008's Wrath of the Lich King. Cataclysm requires 1GB of RAM, higher than the 512MB minimum by Wrath of the Lich King. However, as many gamers know, meeting only the minimum RAM requirement can lead to a choppy, frustrating gaming experience, especially as systems struggle to keep pace with the game's memory demands in highly populated areas.
Memory is not the only issue facing Cataclysm players, however. The game is also a hard drive hog, taking up 25GB of space. In comparison, Wrath of the Lich King used 15GB of hard drive space. For many gamers, the hard drive requirements will be the most difficult requirement to overcome. "There are no real surprises in store — the requirements are really very low, it's just the hard drive that takes a bit of a kicking," Experts sayings when the specifications were announced.
If your hard drive is already filled to the brim and you are in need of an upgrade to play Cataclysm, now might be a good time to consider investing in a new SSD. SSDsare faster and more efficient than traditional hard disc drives.
An upgrade will be worth it. Reviews of the game have been strong, indicating that it is yet another superb entry in Blizzard's flagship franchise.
"Simply put, it is World of Warcraft 2.0. Everything seems to fit in — overhauled graphics, new landscapes, additional quests," Experts.
If you're a WOW fan, you won't want to miss out on Cataclysm, especially due to a computer that is slow or out of space. The game is sure to be one of the biggest releases of the year and you owe it to yourself to make sure you have the hardware to run it.

Emerging technologies are impacting the Flash memory market
According to a recent report from New Electronics, DRAM and Flash memory could be the only successful new memory-related technologies in recent years. The report said many technologies have been developed and pushed toward the market, but none of them have established the reliability, cost-efficiency or sustainability of DRAM or Flash.
As a result, if you are purchasing a new computer you can rest assure that your DRAM will remain valuable for the device's entire life cycle without being completely replaced by a new technology. However, you may need to adjust your notions of purchasing a traditional hard disk drive, because Flash memory technology is allowing solid state drives to become an important part of the hardware market.
SSDs use flash memory to read and write data stored on the device, allowing them to operate at faster speeds than traditional hard disks, which depend on a mechanical device rotating a disk that uses lasers to read and write data. As a result, SSDs are quickly becoming somewhat standard in laptops. The desktop market for SSDs is not necessarily as responsive because the moving parts of a hard drive are not as much of a factor in desktop models. However, SSDs are becoming popular boot drives to improve system startup and overall speeds.
The New Electronics report estimates Flash memory still has about 10 years remaining in its mainstream life cycle. The architecture behind the technology has become cheap enough to manufacture efficiently and sell to mainstream users, and devices that favor SSDs, such as laptops and mobile platforms, are becoming more popular. However, new technologies have the potential to emerge within the 10-year period that could challenge Flash's current stronghold.
One of those challenges, the report said, is the result of an upgrade to current Flash models that uses vertical 3D construction to improve memory capacity. Flash devices work by sending electric signal through small transistors that use the signal to read and write content. Current Flash architecture involves transistors places side-by-side on a memory chip. This not only limits storage capacity, it also allows the electric signal to be disrupted because transistors are closely packed.
According to New Electronics, researches have successfully developed new techniques to essentially stack transistors on top of one another in a vertical, 3D stack. As a result, the disruption between parts of the chip is removed and space limitations associated with horizontal construction is gone. The new method of constructing Flash memory is in the early stages of development, but the report said it could end up offering significant benefits for both the speed and reliability of Flash memory devices.
The report said the 3D method of constructing Flash memory could extend the production life of Flash technologies, such as solid state drives, beyond the 10-year period currently predicted for the technology. Furthermore, this manufacturing technique could keep other new memory-related technologies at bay, keeping Flash-based tools relevant.
According to recent research released by the Bedford Report, 3D Flash memory is already becoming an important tool for high-end Flash devices, and could become mainstream within the next few years. The report said 3D Flash construction makes the chips less expensive than current current Flash technology, which could provide significant benefits to consumers looking for a new memory solution.
Currently, the next technology is most popular in mobile computing devices, the Bedford Report said, but it could develop into a mainstream memory solution that enhances the benefits of Flash memory.

More About Video
The monitor is a passive device that just displays the video output from the system. However, so much data is needed for the constantly changing screen display that special provisions are made for it.
The video card (or video circuitry on the motherboard) has its own RAM memory just to hold the display information, and its own ROM BIOS to control the output. Some motherboards even have a special high-speed connection between the CPU and the video. It’s called the AGP, or Accelerated Graphics Port.
The important numbers in evaluating a video display are how many distinct colors can be displayed and also the resolution, which is how many pixels the image contains across and from top to bottom. Each dot of color making up the image is one pixel. As video technology evolved there have been a number of standards, and each one has its own set of initials like EGA, CGA or VGA. A common one isSVGA, which stands for SuperVideo Graphics Array and has a resolution of 800x600 (that’s 800 pixels across and 600 down). Some high-performance monitors use SXGA (1280x1024) or even UXGA with a resolution of 1600x1200.

More About Disk Drives
Floppies – Although floppy drives are being phased out in some new computers, there are still millions of them out there and you should know something about them. The floppy drive has a little slot on the face of the computer cabinet, and into this slot you can slide a floppy diskette like the one shown here. One of the reasons floppy drives are still around is that it is very easy to take a floppy diskette from one system to another.
Inside the floppy diskette is a round flat disk coated with iron oxide on each side so that data can be stored on it magnetically. This disk is called a platter, and it spins underneath an electro-magnet called the write head that puts data onto the platter surface. There is another head called the read head that copies data from the platter.
Once the disk has made one complete revolution, data is written all the way around. That is called a track. The head then moves a bit and writes another circle of data to create a second track. Altogether, there are 80 tracks on each side, for a total of 160. Altogether, the floppy can hold 1.44 MB (megabytes) of data.
If we are looking for just a few bytes out of 1.44 million, it’s not enough to know which track it is in. To help narrow the search, the track is divided into 18 pieces, calledsectors, which look much like a slice of pie. Each sector holds 512 bytes of data, so if we know the track and sector number of the data we want it won’t be hard to find.
Hard Drives – On a hard drive, data is also organized into tracks and sectors. While each sector still holds 512 bytes, there can be many more tracks and sectors on a platter. There are also multiple platters, one on top of the other like a stack of pancakes. Hard drives can hold much more data than floppies, sometimes into the billions of bytes, calledgigabytes(GB).
Multiple platters require multiple read and write heads, all attached to the same arm so they move together. It’s called an actuator arm. When we are reading track number 10 on the top platter, the other heads are also positioned over track 10 of the other platters, and together all of these track 10s make up a cylinder. To specify the location of data on a hard drive it is necessary to say what cylinder, then the track and sector. Moving the heads from one cylinder to another is called a seek, and the amount of time this takes is the average seek time.
Although hard drives can hold much more data than floppies, the platters are sealed into a metal case that is fastened inside the computer cabinet, so it’s not an easy matter to move from one system to another like you can with floppies. A hard drive is sometimes called a fixed diskfor this reason.
Operating systems use a couple of different methods to keep track of what data is stored where on a drive. One common method uses a table called a File Allocation Tableor FAT, which is a section of the disk with pointers to data locations. There are two versions, calledFAT16 and FAT32. Windows NT, XP and 2000 use a similar method called NTFS.
There are two different interfaces commonly by hard drives to talk to the rest of the system. These are called IDE for Integrated Drive Electronics, and SCSI forSmallComputer System Interconnect. The technical differences are not important at this point, but you should know about the two types because they are not interchangeable.
Figuring out where the heads should go next and then moving them there is the job of some electronic circuitry called the disk controller. Every disk drive has its own controller, which may be on the motherboard or inside the drive itself, depending on the type of drive.
There are a few more things you should know about disk drives before we leave the subject. The first sector of Cylinder 0, Track 0 is called the boot sector, and it contains aMaster Boot Record (MBR) that shows whether the disk contains an operating system and the location of the code. If there is more than one operating system, the drive must be divided into multiple partitions. If not, then the whole drive will be a single partition. All of the disk space assigned to a partition is called a volume.
Another term you will encounter is a disk format. There is a high-level format, which creates a new file allocation table and is done with a FORMAT command. There is also alow-level format that creates a new pattern of sectors. A low-level format must be followed by an FDISK command to create a new Master Boot Record and partitions.
Last, we have the word media. This refers to the actual surface holding the data, which is the platter in the case of a disk drive. Because the floppy platter can be taken out of the drive, it is called removable media, while a hard drive is calledfixed media.
Other Drives – Most systems today, especially home systems, have additional storage drives that use CD or DVD discs. The technology for both is similar but DVDs hold much more data. These drives do not store data magnetically but use optical markings that are read with a laser. They are mostly used just to read data and not to write it. The full name for CD in fact is CD-ROM, which stands forCompact Disc - Read Only Memory. However, there are versions that can be used to write also, and these are called CD-RW and DVD-RW. Even so they are mostly used to write just once for permanent storage, and are not practical for constantly changing data.
Like hard drives, CD-ROM drives can use either an IDE or SCSI interface. The version of IDE for CD-ROM drives is called ATAPI, and for SCSI the CD-ROM version is ASPI.
Because the discs can be removed, CD-ROM and DVD are considered removable media. There are other types of removable media also that are not as common, such as tape drives and Zip disks, which are similar to floppies but with a storage capacity of 100 or 250 MB. Zip disks and tape drives also use the ATAPI interface.

Understanding the Energy Consumption of Dynamic Random Access Memories
Energy consumption has become a major constraint on the capabilities of computer systems. In large systems the energy consumed by Dynamic Random Access Memories (DRAM) is a significant part of the total energy consumption. It is possible to calculate the energy consumption of currently available DRAMs from their datasheets, but datasheets don’t allow extrapolation to future DRAM technologies and don’t show how other changes like increasing bandwidth requirements change DRAM energy consumption. This paper first presents a flexible DRAM power model which uses a description of DRAM architecture, technology and operation to calculate power usage and verifies it against datasheet values. Then the model is used together with assumptions about the DRAM roadmap to extrapolate DRAM energy consumption to future DRAM generations. Using this model we evaluate some of the proposed DRAM power reduction schemes.
