History
What is Computer? And how it started? What is the idea, which amounted to We see now?
Before we answer these questions the meaning back to back with me in an interview Hijacker on the evolution of the history of computers.
Man since the beginnings in the first as he seeks to find all seriousness Means that the availability of help and effort and time is what concerns us here Talk about now is the evolution of the means that he created to assist in the performance ofNumerical and computational functions, and Alalmekd classified to the evolution of computers Three historical phases: --
First: the computer prior to the date:
At this stage, took the rights to see the gravel and the account number and then the evolution of This method to replace the meter invented by the Chinese before the birth B 500, and was a wooden framework of the respective threads hanging Ten workshops and Procedure calculator created by William Aotrd Year 1633 It was used for multiplication and division.
II: Mechanical computers: --
The world has Pascal in 1642 for inventing the first machine collection The IPO consisted of a set of wheels of each wheel is divided into ten Sections of zero to 9 and when the wheel spins full circle move The movement of the wheel, the second one to the next section; haste is a first Sundays and the second and third scores, hundreds, and so on.
In 1822, the Charles Babag design calculator Can carry out arithmetic operations and storage of numbers and print the results The papers on this machine depends on the mechanical means, and then Followed by industry in 1890 working calculator card pierced Hulirt by the world, and then the real nucleus Manufactures computers for a computer -1 Harvard Mark, who has designed World Howard Aiken of Harvard University in conjunction with IBM Cap is a working calculator card perforated, and is Print the results by means of a typewriter heat.
III: Computer-mail: --
The stage began shortly before midnight the previous century has been Researchers to date computers generations reflect each generation for the Time of the computer, namely: --
The first generation 1946 - 1958:
At this stage, vacuum tube was used and this generation is characterized by large Size and the need for conditioning, and the slow speed and the use of Perforated cards from this generation Eniac computer and the computer Univac-1 .
Second-generation 1959 - 1964:
This generation emerged when the scientists used an alternative to the transistor Vacuum tube, which led to the small size of the computer performance and speed And less consumption of electricity and also the ability to distinguish storage view The use of heart-magnetic Magnetic Core and appeared in this period Also floppy discs, and used the language of this generation of high Kalfoertran level in 1957 is this generation computers, and IBM 1401 Honywell 200
Third-generation 1965 - 1970:
Has been used in the generation of integrated electronic circuits used Manufactured on silicon chips Silicon Chip This generation has been less Smaller, and less consumption of electricity and the emission of heat and on the use of Of the terminals. And increased reliance on language-level Have higher language Alpesc Among the most famous of this generation computers IBM360 - NCR395 appeared in the generation of small computers.
The fourth generation since 1971:
Has been used in this generation wide integration services Large Scale Integration is a set of thousands of electronic components On a small silicon chip, as used in Almikrobroissour Computer industry, small and this generation is characterized by high speed Performance and large storage capacity and the emergence of a general-purpose software Management systems and databases.
In this generation on a PC ((PC Personal Computers, appeared cylinders DOS operating system for computers IBM personal computers and compatible with it.
Fifth generation:
A generation of scientists who are now trying to get him out of existence as he tries Directed by scientists for a generation of computers has the ability to perform Kaltvkir mental processes and learning and benefit from the experience ... ...
Commenting on this last point for trying Scientists produced a generation of computers thinker, I believe I have already I Kmqal this opinion in a newspaper that this will not end It features something to satisfy the ego of scientists, I think it's the end of a closed Like many things from the long search by scientists and then it was concluded Did End the call and recall, for example, attempts by scientists urged Clouds to produce rain in areas for which they wish to bring down the rain It did not result in the expenditure of millions of funds in this regard to the on Access is important is the lack of capacity to do so, even when Able to urge the use of cloud lightning industrial rain did not fall to the At the scene of a very large, and the sincerity of the Creator "God take step forward", and when Talking about a simulation of the human mind is impossible, why? Because Rights and feel that it is this sense of self is a human Driving all the other emotions such as love, hatred, and humility, And vanity, etc. ... ... .... The fact that human beings can make the machine think And interact, if it is Valolp will exist in this case Explode all the other emotions what we see happening in the sci-fi movies Computer control of human life, I do not deny that Bsttia scientists to reach the degree of technical expertise in this area. When they say they are in connection with the use of living cells in the organs Computer discovered the tremendous ability to keep the quantities of the terrible Data processing Baltoin electric, but I denied them Strongly to be able to match the human brain's best Vtpark Alkhagayn.
Computer Operating Systems
Now go to explain what the systems and components, but before that Let me review with you in the creation of types of computers, and here we should Dealing with the classification of computers in many ways:
First: in the form of input data: --
1 - digital computer Digital Computer:
Used data from professional or digital type characters or Khaspoho Wider use, such as the PC.
2 - Computer descriptive (analog) Analog Computer:
And intervention in the form of concrete data (such as temperature, humidity, radiation The sun) course, using the means of measurement Kaltermumitr.
3 - Computer Mixed Hybrid Computer:
And take into account in its determination to combine the characteristics of digital computers and computer Descriptive. Among the most famous uses of nuclear reactors and satellites Industry.
Second: The purpose and terms of use:
1 - use of computers in General Computer:
This type is used in many different purposes.
2 - Computer specialist Special Purpose computer:
Designed for use in a specific purpose, such as those in the medical equipment or Washing machines, aircraft, ships and submarines ... ..
Third: in terms of volume:
1 - Computer giant Super Computer:
It is designed for storing and retrieving millions of data is very high speed Used in the military aspects of space research

World Trade Organization
World Trade Organization in 1995. It is one
From the youngest age of global organizations as the World Trade Organization
Khalifa is the General Agreement on Tariffs and Trade (GATT), which
Established in the wake of World War II.
Thus, despite the fact that the WTO is still a modern
The multilateral trading system which was developed originally under the
GATT has reached the age of fifty years. Celebrate the golden jubilee of the system
Geneva in May 19, 1998 the presence of many Heads of State and leaders of
Governments.
Twenty years have witnessed exceptional growth in the last trade
World. Merchandise exports has increased an average of 6% per year and helped
GATT and the WTO to establish a strong trading system
And prosperous, which have contributed to unprecedented growth.
The system has evolved through a series of rounds of negotiations or
Trade, which was held under the banner of the GATT, the concessions the first rounds
Mainly reduce tariffs. The negotiations included the following positions
Others, such as anti-dumping procedures, which do not belong to tariffs. Led
The last round of the 1986 to 1994 to the creation of the WTO
World.
Negotiations did not end at this point, but after some negotiations continued
The end of the Uruguay Round. In February 1997 reached an agreement about the
Telecommunications services with the approval of the Government for 69
Written procedures and a wide-reaching in excess of those agreed upon in Tetum
Uruguay Round.
In the same year the Government has completed four successful trade negotiations, especially
Without tariffs, especially information technology products, and completed
Seventy of the Member States of a special agreement covers the financial services
More than 95% of the trade of banking, insurance and securities
And financial information.
Members also agreed at the World Trade Organization ministerial meeting in
May 1998 to examine the areas of trade resulting from trade
E-World.
In 2000 new negotiations in agriculture and services.
The WTO is the only global organization competent
International laws on trade between nations. The task of
Organization is essential to ensure the flow of trade as smooth as possible
The ease and freedom.
The desired result of that is security. Consumers and manufacturers are
Aware of the possibility of supply by ensuring the continued enjoyment of the goods, while ensuring
A wider selection of finished products, components and raw materials
As well as production services. This ensures all producers and exporters that
Foreign markets will remain always open to them.
The result of all this is to set up a world of economic prosperity
And peace.
Another result is confidence. That consumers and producers know that they
That they can enjoy secure supplies and a wider choice of products
The final components and raw materials and services used by them. And
Producers and exporters know that foreign markets will remain open
Them.
The result is also the world economy enjoyed a prosperous peace
The official further. Are typically decision-making in the organization
WTO Member States and the unanimous ratification of the
By the parliaments of the Member States. Be challenged about the differences
Trade through the mechanism of dispute resolution Trade Organization
World where the emphasis is on interpreting agreements and commitments
And how to ensure that the trade policies of their countries. In this
Low risk way to extend the differences in political conflicts or
Military decline. And the reduction of trade barriers, the WTO system
Global also removes other barriers between individuals and nations.
Decision-making in the WTO usually unanimous
Votes of the Member States and then later approved by the parliaments of
States. Transformation of any trade dispute to the dispute settlement mechanism in the
Organization where they are resorting to the conventions and treaties to ensure that
Systems and trade policies of the States in conformity with it. In this way
Shift the risk of disputes to the political or military conflicts reduced
A lot. And to reduce barriers to trade lead Trade Organization
The world to reduce barriers between the United States.
That the focus of the system known as the multilateral trading system is
WTO agreements and signed by a majority of States
World trade and approved by their parliaments. Those conventions are the foundations
And legal norms of international trade on the basis of contracts which ensure
Member States of the important trade rights Governments are also required to maintain
The continuity of their business within the limits of acceptable
The benefit of all.
The conventions discussed by Governments and by non-government
The purpose of these conventions in the foundation is to help producers of goods
And goods and service providers, exporters and importers to manage their business
Successfully, which leads to the interest and welfare of the peoples of Member States
Terms of Reference.
The main objective of the World Trade Organization is to assist in the entry into force
And the flow of trade and Bslaslp expected and freely.
The organization does so by:
Management agreements on trade.
Presence of a forum for negotiations on trade.
Resolution of disputes relating to trade.
Review of national policies relating to trade.
Assist developing countries in trade policy issues
Through technological assistance and training programs.
Cooperation with other international organizations.
Structure
The membership of the World Trade Organization more than 140 members representing
More than 90% of world trade. The 30 others are negotiating
Regarding membership.
Decisions are made by all members, be unanimous. Was
Ratification of the WTO agreements by the parliaments of
All Member States.
The supreme body of decision-making in the WTO
Global is the Ministerial Conference which is held once every two years
Least.
The General Council in the following list (including ambassadors in general
The heads of delegations in Geneva, but sometimes includes officials from the missionaries
Capitals of the Member States), which is held each year in Adpmrat Headquarters
Geneva. The General Council meets as a policy review body
Trade, as well as the resolution of disputes.
There is the next level in both the goods and services and the Council
Intellectual Property (TRIPS), which reports to the General Council.
Handle many of the specialized committees and working groups and task forces
With the conventions, the Convention on the unit and other topics such as the environment
The development and membership applications and regional trade agreements.
His first ministerial conference in Singapore in 1996 three working groups
This new structure. And specializes in the relationship between trade and investment
And the interaction between trade and competition policy, transparency in
Government procurement. At the second ministerial meeting in Geneva in 1998
Ministers decided that the World Trade Organization will examine also the subject of
E-commerce, a task which will be divided between the councils
The existing committees.
Ten advantages of the trade regime of WTO
Allow the World Trade Organization and many of the trading system
Advantages and benefits, some known and others are not clear, since
Organization seeks to create a more peaceful world through the money that we have
And goods and services we use that we enjoy.
World is very complex: this text shows some of the benefits of the system
The multilateral trading the World Trade Organization, although the text was not invited
That the system free of defects, if so, what was there
Need for further negotiations and discussions and that the rules are reviewed
For the development and continuous improvement. Nor can the claim that
All agree on everything in the World Trade Organization. This may
Is one of the main reasons for the existence of a system: it is a forum in which the circulation
The differences of views between States on matters relating to trade.
This means that there are many reasons why the existence of the system
Advantage of the presence and absence of the following ten advantages.
Ten advantages of a global trading system
1 - support system and strengthen the peace.
2 - The address conflict constructively.
3 - lead to lay the foundations and rules to make life easier for all.
4 - reduce the most liberal trade regime for life.
5 - expand the trading system more liberal than the range of options in products
And quality.
6 - Free trade increases income.
7 - free trade stimulates economic growth.

Swine flu infection is ?
Swine flu infection is a contagious disease is spread through breathing. Transmitted when the pigs due to the proliferation of Class "A" virus "influenza." The transmission of the virus to humans is not common, but is likely if the friction with the permanent pigs.
According to the World Health Organization, the transmission of infection among humans may be due to the emergence of a new species of this virus is transmitted among humans.
What are the symptoms of this disease?
Symptoms of the disease are similar to seasonal influenza symptoms: fever, cough, runny snotty, joints and muscles. These symptoms are difficult to delayed diagnosis and treatment of the epidemic can cause chest disease may be fatal.
How the virus spread?
Infection is usually transmitted from pigs to humans, but the recording of cases of infection occurred among the people themselves through breathing. This epidemic is not transmitted through eating pork.
Is there a new type of swine flu?
As is the case in humans, the influenza viruses are constantly changing with the pork. When the pigs in the respiratory apparatus, are sensitive to the MBC as the most watched on influenza viruses and human or pig influenza. Pork is a "focal point" is conducive to the emergence of new influenza viruses by genetic combinations in cases of concurrent infection.
Such hybrid viruses concern the emergence of a new flu virus, such as a severe flu, but is subject to, such as the transmission of human influenza. This type of virus, which is unknown to the human immune system, may include specifications necessary for the spread of pandemic influenza on a large scale.
Any cure for this epidemic?
There are preventive measures of this disease is to isolate the injured, wearing breathing masks, wash hands constantly. There is Antidote to the epidemic but it turned out ineffective. There are also vaccines to prevent the proliferation of anti virus within the body.
There is a vaccine against the disease of pigs. It is not for humans. The Mexican authorities announced, citing the World Health Organization that the vaccine is still in conformity with an earlier version of the virus to make it less effective. But "the production of a vaccine is possible if the virus has been identified," but requires "some time" said the World Health Organization.
Degrees of warning by the World Health Organization:
Class 1: The risk of a limited threat to rights.
Class 2: The risk of a slightly larger threat to human
Class 3: Non-existence or the existence of some cases of infection among humans.
Class 4: transmission between humans and the evolution of the degree of the epidemic.
Class 5: the virus is spreading among humans in two, at least in one region.
Class 6: transmission to the global level and the recording of cases in more than one region of the world
