What does RAM do?


RAM - Random Access Memory, or volatile memory, is used by the system to store data for processing by a computer's central processing unit (CPU), also known as the processor. RAM stores the data in memory cells that are arranged in grids much like the cells are arranged in a spreadsheet, from which data, in the binary form of 1's and 0's, can be accessed and transferred at random to the processor for processing by the system's software.

The data stored in a hard disk drive (HDD) cannot be accessed at random. Whole sectors, containing blocks of data, are transferred from a hard disk drive, placed in a large swap file on the same drive, and only then are selected files transferred to RAM for random access by the processor, which is itself only performing the instructions of the system's operating system (usually Windows), and its application software.

When the computer is turned off, all of the data in the RAM memory is lost, hence its alternative name of volatile memory, whereas all of the data on a hard disk drive is retained permanently until it is intentionally erased. The motherboard (or mainboard) manual (that should be provided with a new or a second-hand PC) will provide all of the details about the different types of supported RAM, and the various combinations of modules per bank for each type that can be successfully installed.

In this first of many i am going to try and show how different parts of the computer works. I hope that this will help some of you to understand whats happening under your desktop or laptop.

First of all is the processor:

Combat Arms, a free FPS????


In the video game industry today, we look for a game with the best graphics and the best gameplay. There are some major contenders who bring home the bacon with a combination of both but there are many companies who are lacking it all. Nexon America, a sister company to Nexon Korea, has released their latest game called Combat Arms. With many free games on their list, how can a small company who makes their money with item shops possibly make a game where it combines depth, action, and sheer fluidity to a game and still be free? No one knows the answer, nor is it ever asked and it shouldn't. Combat Arms definitely does deliver what all FPS gamers need and shows potential with where it can go.

You start the game with a basic setup. You choose how your soldier looks and then name him. Where it gets tricky is the weapons you start with. They consider the M16A1 Automatic rifle to be the weakest by today's standards and therefore offer it as its "free" weapon. You also start with standard military issue camo and a combat knife as well as some basic frag grenades. As for now, customization is very limited but the developers have stated that you will be able to "purchase" looks in the future, which leads me to the best part. EVERY gun, grenade, armor vest, helmet, uniform, or anything else that can be used to punish your enemies will never EVER cost you any real life money. Thats right. You can be just as powerful as the highest killer on the servers and never have spent a penny. The ingame money, known as GP, is what you use to buy your gear with and is only earned by winning matches. Depending on how many kills you get determines what place you come in on the leaderboards for that match and thus, determines how much experience and GP you earn.

Experience? Why is there experience points in an FPS? Actually, this is nothing new. In the Battlefield games, your soldier earned experience to unlock weapons and to earn rank. The same is true in Combat Arms. You earn rank to unlock certain weapons and gear. You also have to be a certain rank to join a clan and start one. This leaves an incentive to playing the game and really pushes the player to rank up instead of creating multiple accounts. There is also a KDR (Kill/Death Ratio) which is available for all players to see. Naturally, the higher your KDR is, the better you look to other players, and believe it or not, determines whether opposing clans will fight you in clan matches or even play in the same match with you in normal matches. Rank does not determine how good a player is however. Rank is merely an indication on how much that player has played and there are definitely some people on there with a rank so high that it looks as if they have no life. Which is probably true.

So how is the gameplay? The gameplay is the next best thing about Combat Arms. The gameplay feels a lot like Counterstrike meets Unreal Tournament. There is blood and lots of it as well as tactical espionage action. There is four gameplay modes and each are unique in their own way.

Elimination: Players are put on two teams: Alpha and Bravo and are pitted against each other in a deathmatch. The team with the most kills wins.

One Man Army: Exactly as it sounds. You are your own team in the ultimate of deathmatches.

Search and Destroy: Players are again placed into two teams: Alpha and Bravo. Each member of Alpha has control of a bomb and must reach locations A or B (Marked by Chevron's on the HUD) and must plant the bomb. Bravo team must either destroy all of Alpha teams members or disarm the planted bomb. Players have one minute from the time the bomb is planted to disarm it.

Capture the Flag: Ah, ye olde Capture the Flag. Probably the most common of game modes for any FPS on the market. Capture the Flag consists of yet again, two teams. Alpha and Bravo. The rest is pretty self explanatory, each team must try to capture the opposing teams' flag.

One of the major concepts about Combat Arms that makes its gameplay unique, is the sense of "reward" you get from killing your enemies. For every kill you get, it flashes how many kills you have in front of your face. And it is even more rewarding if you can kill two to three players in less than five seconds. It boldy states "Double Kill!" or "Multi Kill!". And it is also seen by other players. Very rewarding indeed.

There are some flaws to this game however. (Which games doesn't have flaws?) The game is really laggy during peak times, no matter which server you choose. There is also an ever increasing amount of hackers, and the game has several glitches. Like falling into the world and and knifing everyone. But all in all, it is a very good game with montly updates/fixes that will be sure to have you playing more and more as time goes by.

Acer Aspire One Review


Build and Design

When you first get the Acer Aspire One out of the box you really appreciate the quality of the product you have just bought. The netbook feels solid and well built, and the glossy white looks very sleek with the rounded corners on the unit. The white itself is more of a pearl white, which seems to look really very good with the more traditional white keyboard. The screen is surrounded by a black bezel, and I would say that it looks good, but think it may have looked better white as well.

The size of the netbook is very satisfying, seeming to be larger than the Asus eee pc making it very much usable, yet small enough to make it still very much portable.
When closed it is very rigid and seems to have enough strength to avoid resist flex and compression.

The Acer Aspire One is a relatively hard netbook to make any adjustments to. Rather than having a panel to which you can unscrew and add extra RAM, you have to practically take apart the entire bottom plate of the netbook, so not too great for people who may want to run vista with some added RAM that it needs.

Keyboard and Touchpad


The keyboard is very spacious for a netbook, since the Acer Aspire One is a 9" screen PC in a 10" body. The keyboard is a little cramped compared to a full size notebook keyboard but is nothing that you can't get used to. The keyboard seems quite strong and seem to be very reactive.

The touchpad's design is slightly different to other netbooks on the market as it has the left and right mouse clicks on either side of the touchpad, rather than at the bottom. This is to save space but you do find yourself moving the mouse when you're trying to reach for the left click that isn't there. The sensitivity of the touchpad s great, and this can be adjusted easily.

Display


The screen is very clear and vibrant, making any text on the LED backlit screen very easy to read. Any colours look very nice on the glossy screen but this does mean that the screen reflects far to well, making it almost useless outside when it is sunny. Viewing angles however are very good especially the horizontal ones.

Performance

Like all netbooks the Acer Aspire One contains the Intel Atom processor, and although this would be a problem should you try to run any major games on it (plus the fact there is no dedicated graphics card in it) for practically everything else it runs fast and smoothly. Even photo editing tasks were handled with ease and the hard drive that is on my model is more than enough space.

Operating System


I bought my netbook with Linpus Linux Lite installed on it, mainly for the reason that I knew that it would run faster than Windows XP would and also because it was cheaper. With Linpus installed the netbook fired up very fast, around 20 seconds. However that is mainly where the good things about Linpus end. The basic applications installed are OK, but for anyone who wants to add more of their own choice of applications, audacity for example, it seemed nigh on impossible. So I decided to go and download the Ubuntu Netbook Remix, and try that out, and its great. It has all the good things about Linpus, the easy to use layout, the fast boot up time, and yet also is really easy to add your own applications and software, simply through the add and remove application. I'll be talking more about the advantages of UNR (Ubuntu Netbook Remix) in my review of the operating system in the future.


For those of you who want Windows XP, then I warn you that many people have said it does just what I can do on my normal computer, just slower. Now this may be a good thing because there are lots more things you can install on XP, but if all you want your netbook for is to do simple things and leave anything major to your desktop, then i recommend buying the Linpus version, because it is cheaper, and then downloading UNR, which is free, and following my guide to install that as t really is very good.


Hope you have enjoyed my review and can decided whether to buy one or not.
Thats all for now
