Our computers are very important to us nowadays because we have all become used to working with them on various occasions. We have also become more interested in learning all about the way in which our computers function, all about their components and their role inside our computers and this can only make us become better computer users.
There are numerous computer hardware components that are very important for the way in which our computer functions because they have specific functions which are very important in determining the performance of our computers. In this article, we shall discuss about one of these hardware components, namely the central processing unit and this is because the CPU is one of the most important computer hardware components and all computer users should be familiar with it and its functions in order to get a better understanding of the way in which their computers function.
What might be interesting to be mentioned in the beginning is the fact that in the past, computers used to have specific processors developed for various purposes. This led to the necessity of creating computers with specific purposes in mind, which made it quite difficult for computer user to have very well performing computers that they could have used for various purposes as it is known to be possible nowadays. The idea is that every computer processor can only understand a limited number of so-called instructions and each instruction of this kind includes logical type of operations that need to be performed so as to enable the completion of specific tasks.
In time, there have been made certain chances or better said improvements to computers but taking into account the aspects having been previously mentioned. The main goal had become that of creating a processor that might be used for multiple purposes rather than having to develop a new processor for each type of computer that was available on the market. The advantages of creating a processor of this kind were more than obvious and the main one refers to the great reduction of manufacturing, research and development costs in the case of such processors. This is how the term CISC technology has become familiar on the market as well for those who are not yet aware of its meaning we should day that it stands for Complex Instruction Set Computing and that it used to combine different necessary instruction into a single central processing unit. The main idea regarding this type of technology refers to the fact that each instruction could perform various tasks with the help of mini-programs or macrocodes integrated in the central processing unit.
Drawbacks have also been discovered to be presented by the CISC technology in the case of the CPU, one of the most important computer hardware components. First of all, a complex processor was required so as to enable the use of an increased number of instructions and this meant using millions of transistors. Also, calculating where each of the performed instructions has began and ended took the processor quite some time. These are two of the drawbacks that have been considered in time in what concerns the use of this type of technology in manufacturing central processing units for our computers.

Name Five Hardware Components For My Personal Computer!
Published by warepin, on November 7th, 2009, in the categories: CPU, Hard Drives, Mainboards, Sound Cards
We use computers on a daily basis, at home, at work or while traveling to access the Internet, play computer games, watch movies and so much more. Yet, most of the times if not ever, we never give a second thought to just what our computer is made off. You know it contains hardware components but what exactly they are, how are they called or what is their function within our personal computer are usually questions without answers or with vague ones. I'm going to be talking bellow above about the hardware components for a personal computer that are essential to it:
1. The PC Monitor is the device on which you visualize movies, games, and programs like word editors and Internet browsers. Older models featured a Cathode Ray Tube (hence the name CRT) with controls housed in a plastic case. Their diagonal ranged from 13 to 21 inches. Today LCD monitors have flooded the market, providing wide screen image display and smaller weight compared to their older counterparts, the CRT computer monitors. Most monitors feature controls used to adjust contrast and brightness while others have options to move the image left, right, up or down. CRT monitors also have a degauss option which can be used when the image isn't displayed correctly.
When it comes to picture quality we basically speak of resolution and refresh rate. Resolution is measured in pixels and is connected with how well our monitor displays images. Refresh rate refers to how often your image quality gets refresh. The recommended quality is usually 60 Hz, but since there are so many types of monitors it is best to consult the monitor's manual for the right value. Bear in mind that using a different value other the one recommended in your manual can damage your monitor.
2. The motherboard is the board that contains the CPU, the memory, BIOS, CMOS, Video devices, sound devices, storage devices, chipsets, etc. together with the connectors and logic circuits that tie all parts of your PC together. Together with the wiring in your computer it resembles to the network of veins in your body.
3. The CPU (Central Processing Unit) is considered by some to be a computer inside another computer. This isn't to far from the truth since the processor manages the huge number of instructions given to him by the other computer hardware components similar to how the computer manages the instructions you give it by using external input devices like the keyboard and mouse.
4. The "hard drive" is a storage device with one or more metal disks (called platters), arranged on a spindle, one above the other; with a read/write head (often on an arm that can be moved to a specific point on the recording surfaces. This read/write machine can probably be called the first true 'robot'. Hard drive units are sealed hermetically to keep out dust. Even the smallest particle of dust can damage the platters so it's recommended you don't open them. The most recent hard drives can have up to 1.5 Terra Bytes.
5. The video card is an essential part of any computer. It provides your computer to play video files, computer games and other things. Without a video card to convert the binary code from the CPU and transmit in a graphic way to your monitor you wouldn't be able to watch anything. In some cases the video card can be integrated on the motherboard.
6. The sound card is very much like the video card, with the small difference that instead of converting CPU binary code and send it to your monitor it uses a different type of conversion allowing you to hear sounds in your computer speakers.
7. Over the years the CD-ROM drive and the DVD-ROM have proven to be essential to a personal computer. Information transfer had at its heart this hardware component. In recent years, with the development of the Internet, flash drives and portable hard drives, CD and DVD-ROMs have started to register a slow decline from the information transfer market. They will still be around for some years to come since they are the backbone of the music and movies commercialization.
8. As a last entry to the list of computer hardware components I'll add a duo of hardware parts, namely the keyboard and the mouse without which you couldn't control you computer. That is until technologies similar to the touch screen will appear on the market, but this will undoubtedly take some time.

Intel Atom 330 Dual-Core
Published by Bogdan Alex, on September 8th, 2008, in the categories: CPU
A great demand of mobile and ultra-mobile PCs has been recorded over the past months in Asia and the American continents and with the advancements in CPU technology we can now tap a pretty big amount of processing power by using only reduced form-factor PCs. To provide this processing power, Intel came up with the Atom CPU, specifically designed for the new wave of compact mobile PCs. AMD was quick to point out that already had an answer to the Atom architecture and it recently turned out that these CPUs were faster than the Atom, although needed a bit more power to run. Now Intel wants to bring the dual-core Atom and take the compact mobile PCs to another level.
Rumors about the dual-core Atom have started to circulate on the Internet since May 2008, but Intel has managed to prevent any major information leak about the CPUs up until recently. The guys over at Engadget China somehow got hold of a dual-core Atom and some info on the new architecture. The CPU you see in the above image is supposed to be the new Atom 330 dual-core and should be officially launched some time in October.
Atom 330 is expected to provide more than double the processing power offered by its predecessor, thanks to its two cores working at 1.6GHz with four threads. The CPU package also integrates 1MB of L2 cache and will work with a 533MHz FSB. Atom 330 is going to be included in the next wave of nettops, netbooks and ultramobile PCs arriving Q4 2008.

Fall CPU Roadmap from AMD
Published by Bogdan Alex, on September 7th, 2008, in the categories: CPU
While AMD concentrates almost entirely on the latest details of the 45nm Deneb launch, it still manages to find enough time to take care of some soon-to-be released entry-level and mainstream chips.
Initially expected to hit the market in early 2009, the 45nm CPUs from AMD appear to be a bit rushed, since a new leaked document obtained by CHW shows that December should see the start of production of the new Phenom quad-core X4 chips with 45nm architecture, and these are not featuring the Deneb micro-architecture. It appears that the new CPU’s are only dye-shrinks of the existing ones and are rated at 3.0GHz and 2.8GHz, using up 125W of power. As always, the volumes will be minimal in December and the CPUs are expected to be available worldwide only in January 2009.
The leaked document also mentions that the 15W AMD Athlon 2650e – expected to compete with the Intel Atom – is scheduled for a November release, with a clock speed reportedly rated at 1.5GHz. A faster dual-core X2 3250e rated at 1.5GHz and using up 22W of power is also going to be released in order to compete with the upcoming dual-core Atom. Both CPUs are said to have slightly higher power requirements than their Atom counterparts, but AMD is confident they’ll end up faster and cheaper.
Other CPUs that will be launched this fall include a dual-core Athlon X2 processor, model number 5050e, with a 2.6GHz clock speed and low 45W power consumption, plus a three-core 8850 chip rated at 2.5GHz and 95W of energy use. OK, enough with this entry-level stuff; we want the Deneb!

Intel Releases First Six-Core This Month
Published by Bogdan Alex, on September 6th, 2008, in the categories: CPU
In the beginning (circa 1970) there were the mono-core CPUs, and they’ve dominated the market for more than three decades. The last four years brought the dual and quad-cores and the next logical step looks to be six and eight cores. Intel mentioned that Nehalem six-cores will be introduced later in 2009, but it looks like the Core i7 CPUs won’t be the first six-cores to hit the market from Intel. The CPU giant already intends to release a series of native six-cores in the second half of September, but it’ll be server-oriented.
The native six-core CPUs bear the Xeon 7400 brand name and were codenamed Dunnington. According to CNET, the Xeon 7400 series will be manufactured at 45nm and will feature a shared 16MB L3 cache. The new CPUs are socket compatible with the previous Xeon 7300 series, so there won’t be any need to buy new motherboards. The 7400 series is also compatible with the Xeon MP standard and are intended for systems using four or more CPU sockets.
Don’t expect to see any cheap components here as these are server CPUs after all. The top of the line model – Xeon X7460 – is expected to be available for $2,651, but there are cheaper models going all the way down to just a little over $1,000. Anyway, I still think that a quad-crossfire setup with four Radeon HD 4870X2 graphics cards performs better than a 24-core server.
Later edit:
This is just one example of a powerful dedicated server that can run relatively high load websites.
