Q: What is FPU ?

A: FPU, it is a Floating Point Unit. And better to say, it is the block making operations with a floating point (often speak as a comma) or the mathematical coprocessor. FPU helps the basic processor to carry out mathematical operations over material numbers. Here it is necessary to specify that at first it was applied optionally, as the additional processor. Directly in crystal of processor the FPU was integrated for the first time in 1989 (processor Intel 80486).

Q: What is System Bus?

A: System Bus (FSB = Front Side Bus or System Bus) serves for the communication of the processor with other computer. The processor has two frequencies: internal and external. Internal, it is which is its basic characteristic. External frequency, is frequency of work of the system bus. For Pentium 3 frequencies of the system bus in 100 and 133Mhz were characteristic. At the first Pentium 4 real frequency of the bus makes 100Mhz, but is transferred four packages of the data for a step, i.e. Speed of data transmission has turned out as at 400Mhz. A resultant (effective) frequency in that case – 400Mhz, at 133MHz FSB – accordingly already 533Mhz, and at 200MHz – 800MHz. At Athlons transfer goes on both fronts of a signal, as a result effective speed doubles. Also the system bus is a basis for formation of frequency of other buses of data transmission of the computer – AGP, memory, PCI, by multiplication to certain factor. For the inquiry – the frequency of the bus PCI – 33MHz, AGP 1x – 66MHz, AGP 2x accordingly 133 MHz and so on. For example, at FSB 100 MHz frequency PCI is formed by multiplication FSB on 1/3. Though there are also exceptions – a chipset nVidia nForce2, where the given frequencies (PCI/AGP) are tacked separately.

Q: For what is necessary the cache memory of the processor ?

A: Modern processors work faster, than memory (besides – various “blocks” of processors work on various frequency (speed)), and in due course rupture between these speeds becomes more and more. The more slower the memory, the more processor has to wait for new data from it and to do nothing. In a memory cache there are machine words (it is possible to name them the data) which are used by the processor more often. If it needs any word at first it addresses to a memory cache. Only if there is not there, it addresses to the basic memory.

There is a localization principle on which into a cache together with a word demanded at present are loaded as well the words next to it , because there is a high probability that they will be necessary in the near future. In modern desktop processors exist two levels of cache-memory (for servers exists processors with the third level of a cache, it also has P4 Extreme Edition).

The cache of the first level (Level 1 = L1) is usually halved, half is allocated for the data, and other half under instructions. The cache of the second level (Level 2 = L2) intends only for the data. Throughput of operative memory is certainly high, but the cache memory works several times faster. At old processors (Pentium, K6, etc.) microcircuits of cache L2 were on the motherboard. Speed of work of a cache thus was enough low (equaled to frequency FSB), but it was enough.

Normal at present is considered to be the volume of cache L2 512Kb for Pentium 4, and 256Kb for Athlon ?? (though processors on kernel Barton also have 512Kb). In some cases the big cache is rather useful (games, 3D-renering, work with databases). However on the one hand, the more the cache, the better, but on the other hand, with the cache increase g increases sample time (search and extraction) the data from it. Though the increase in cache L2, despite it, almost always gives (different in size) a gain on speed.

More Words on the Definition of Viruses:

Virus – is a small computer program which can copy and extend from one computer machine to another, it can be either with the aid of the user or without it. However, viruses typically more than only are multiplied, which is bad enough in itself because it is resources of system of devourers of resources. Something else that viruses are programmed to make, from display of irritating messages to destruction of files, they are named as useful loading. Often, they cannot put the useful loading, yet not suspecting user does something to force a virus to execute the programmed function. It could be so simple as pressing innocently looking attachment of a file ?.exe (feasible) extension.

We speak about the Virus neutralization:

The majority of viruses extend through the mail attachments, because it is the most simple way. Though Macintosh, Unix, and systems Linux can find out viruses, the hackers especially strongly like to use vulnerability of safety Microsoft, especially Microsoft Outlook. Because of popularity of this software hackers have maximum satisfaction from continuous reminders Microsoft that to be big does not mean that You are perfect.

What do you know about Mobile Viruses? Are they a real danger or simply a myth?
Nowadays, the information is one of the most expensive products. And as any other product, it can be sold and bought. And still the information can lose reliability or in general to get lost. If the first happens because of a carelessness of its owners, the second happens because of failures in the hardware of devices of data storage. But sometimes the information loss occurs on someone’s malicious intention — because of viruses. Until recently it was believed (and many assume and now) that such devices as mobile phones and a pocket computers, are not subjected to this danger. Actually, all has appeared on the contrary.

The time has come…..

The idea of viruses in mobile devices has arisen for a long time, but couple years ago the experts and usual users yet did not consider it as their big problem. Obviously, the small prevalence of the target devices and a small amount of channels of transfer of viruses on these devices was the reason of such inattention. But approximately one year ago the idea of mobile viruses again began to be discussed very actively. And experts did not come to the common opinion: some considered mobile viruses as a far-fetched problem which never to become a reality, some assumed activity splash in the near future and advised the users to be cautious. Anyhow, there was a first real virus-concept for mobile phones this summer.

Spammers and Hackers …..

Recently the bad tendency of association of spammers and hackers was outlined. The last create viruses, which transform the infected computers into “zombie”, which can be operated on distance (the same Brador) including to dispatch the spam. For example, it is possible to create the program which will be not simple to scan an ether on presence of nearby Bluetooth- devices, but also to send on them advertising messages. However, the mobile devices in the near future will hardly probable threatens the fear to become the zombie as they are a little interesting to spammers because of their rather small computing capacity and prevalence.

You must not only to protect but also to secure the computer life. The cyber terrorists are no longer considered to be as the isolated problems.

The large and small companies, the organizations, and even the personnel are pursued every day by the computers. It is the international problem.

The viruses which run on your computers, grasping your data and a forgery parcel sends by e-mail to your friends and your business partners.

Hackers who work with any computer, only for the sake of the thrilling feeling , to see, whether they can cope with all that. The computer owners neglecting to execute backup copies and it is a sad loss of their “life” when a virus attacks and their computer failures. Going in for surfing in the Internet, all leaving “almost invisible traces of where you have been.

To support balance of protection against an external world, you should know that there are at least four important things EACH owner of the computer should have or make. You need to make some steps and by that way you can protect and maintain the protection of your most important or the vulnerable data.

Here are these steps:

1. Virus Scanning or the protection

2. Personal System of network protection

3. Backup copies

4. it is important to clean your Cache, Chronology, and Cookies

VIRUS Scanning or the protection:

According to mcAfee.com, on September, 26th 2001, the best 10 viruses have infected 117 427 computers and 962 767 files has been infected all over the world in last 24 hours.

Usually a virus is sent through e-mail, to e-mail or as an attachment.

The sender usually does not understand that they have sent you a virus.

They do not know that they have a virus, they do not know that a virus has attacked their address book and sends e-mails to e-mails that are listed in their address book, together with a virus.

Do you know that someone sends a virus to you, so you must take the following precautions, which you should treat seriously, otherwise your computer is at stake:
Six precautions against the Virus:

1. If you do not know who sent you this or that e-mail or any other information, do not open any attachments.

2. Ask the information which was sent as an attachment to be sent again or to put this information into the e-mail.

3. Buy the virus scanner, which will check your computer regularly! Make sure it is working all the time.

4. Make sure that your virus scanner is included (admitted) to scan entering e-mails and loadings.

5. Update the virus scanner regularly, especially when you hear about the new virus, which is working as the unrestrained.

Your PC can get into serious problems if you do not pay attention to the regular update of the drivers. And this is where driver updater can save you much time.

We would like to give you a final piece of advice – today the Internet technologies give you a really unique chance to choose exactly what you want for the best price on the market. Funny, but most of the people don’t use this opportunity. In real life it means that you should use all the tools of today to get the info that you need.
