Poland the Republic of Poland, is a country located in Central Europe. It is divided into 16 administrative subdivisions, covering an area of 312,696 square kilometres, has a temperate seasonal climate. With a population of 38.5 million people, Poland is the sixth most populous member state of the European Union. Poland's capital and largest metropolis is Warsaw. Other major cities include Kraków, Łódź, Wrocław, Poznań, Gdańsk, Szczecin. Poland is bordered by the Baltic Sea, Russia's Kaliningrad Oblast and Lithuania to the north and Ukraine to the east and Czech Republic, to the south, Germany to the west; the establishment of the Polish state can be traced back to AD 966, when Mieszko I, ruler of the realm coextensive with the territory of present-day Poland, converted to Christianity. The Kingdom of Poland was founded in 1025, in 1569 it cemented its longstanding political association with the Grand Duchy of Lithuania by signing the Union of Lublin; this union formed the Polish–Lithuanian Commonwealth, one of the largest and most populous countries of 16th and 17th century Europe, with a uniquely liberal political system which adopted Europe's first written national constitution, the Constitution of 3 May 1791.
More than a century after the Partitions of Poland at the end of the 18th century, Poland regained its independence in 1918 with the Treaty of Versailles. In September 1939, World War II started with the invasion of Poland by Germany, followed by the Soviet Union invading Poland in accordance with the Molotov–Ribbentrop Pact. More than six million Polish citizens, including 90% of the country's Jews, perished in the war. In 1947, the Polish People's Republic was established as a satellite state under Soviet influence. In the aftermath of the Revolutions of 1989, most notably through the emergence of the Solidarity movement, Poland reestablished itself as a presidential democratic republic. Poland is regional power, it has the fifth largest economy by GDP in the European Union and one of the most dynamic economies in the world achieving a high rank on the Human Development Index. Additionally, the Polish Stock Exchange in Warsaw is the largest and most important in Central Europe. Poland is a developed country, which maintains a high-income economy along with high standards of living, life quality, safety and economic freedom.
Having a developed school educational system, the country provides free university education, state-funded social security, a universal health care system for all citizens. Poland has 15 UNESCO World Heritage Sites. Poland is a member state of the European Union, the Schengen Area, the United Nations, NATO, the OECD, the Three Seas Initiative, the Visegrád Group; the origin of the name "Poland" derives from the West Slavic tribe of Polans that inhabited the Warta river basin of the historic Greater Poland region starting in the 6th century. The origin of the name "Polanie" itself derives from the early Slavic word "pole". In some languages, such as Hungarian, Lithuanian and Turkish, the exonym for Poland is Lechites, which derives from the name of a semi-legendary ruler of Polans, Lech I. Early Bronze Age in Poland begun around 2400 BC, while the Iron Age commenced in 750 BC. During this time, the Lusatian culture, spanning both the Bronze and Iron Ages, became prominent; the most famous archaeological find from the prehistory and protohistory of Poland is the Biskupin fortified settlement, dating from the Lusatian culture of the early Iron Age, around 700 BC.
Throughout the Antiquity period, many distinct ancient ethnic groups populated the regions of what is now Poland in an era that dates from about 400 BC to 500 AD. These groups are identified as Celtic, Slavic and Germanic tribes. Recent archeological findings in the Kujawy region, confirmed the presence of the Roman Legions on the territory of Poland; these were most expeditionary missions sent out to protect the amber trade. The exact time and routes of the original migration and settlement of Slavic peoples lacks written records and can only be defined as fragmented; the Slavic tribes who would form Poland migrated to these areas in the second half of the 5th century AD. Up until the creation of Mieszko's state and his subsequent conversion to Christianity in 966 AD, the main religion of Slavic tribes that inhabited the geographical area of present-day Poland was Slavic paganism. With the Baptism of Poland the Polish rulers accepted Christianity and the religious authority of the Roman Church.
However, the transition from paganism was not a smooth and instantaneous process for the rest of the population as evident from the pagan reaction of the 1030s. Poland began to form into a recognizable unitary and territorial entity around the middle of the 10th century under the Piast dynasty. Poland's first documented ruler, Mieszko I, accepted Christianity with the Baptism of Poland in 966, as the new official religion of his subjects; the bulk of the population converted in the course of the next few centuries. In 1000, Boleslaw the Brave, continuing the policy of his father Mieszko, held a Congress of Gniezno and created the metropolis of Gniezno and the dioceses of Kraków, Kołobrzeg, Wrocław. However, the pagan unrest led to the transfer of the capital to Kraków in 1038 by Casimir I the Restorer. In 1109, Prince Bolesław III Wrymouth defeated the King of Germany Henry V at the Battle of Hundsfeld, stopping the Ge
The United Kingdom the United Kingdom of Great Britain and Northern Ireland, sometimes referred to as Britain, is a sovereign country located off the north-western coast of the European mainland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, many smaller islands. Northern Ireland is the only part of the United Kingdom that shares a land border with another sovereign state, the Republic of Ireland. Apart from this land border, the United Kingdom is surrounded by the Atlantic Ocean, with the North Sea to the east, the English Channel to the south and the Celtic Sea to the south-west, giving it the 12th-longest coastline in the world; the Irish Sea lies between Great Ireland. With an area of 242,500 square kilometres, the United Kingdom is the 78th-largest sovereign state in the world, it is the 22nd-most populous country, with an estimated 66.0 million inhabitants in 2017. The UK is constitutional monarchy; the current monarch is Queen Elizabeth II, who has reigned since 1952, making her the longest-serving current head of state.
The United Kingdom's capital and largest city is London, a global city and financial centre with an urban area population of 10.3 million. Other major urban areas in the UK include Greater Manchester, the West Midlands and West Yorkshire conurbations, Greater Glasgow and the Liverpool Built-up Area; the United Kingdom consists of four constituent countries: England, Scotland and Northern Ireland. Their capitals are London, Edinburgh and Belfast, respectively. Apart from England, the countries have their own devolved governments, each with varying powers, but such power is delegated by the Parliament of the United Kingdom, which may enact laws unilaterally altering or abolishing devolution; the nearby Isle of Man, Bailiwick of Guernsey and Bailiwick of Jersey are not part of the UK, being Crown dependencies with the British Government responsible for defence and international representation. The medieval conquest and subsequent annexation of Wales by the Kingdom of England, followed by the union between England and Scotland in 1707 to form the Kingdom of Great Britain, the union in 1801 of Great Britain with the Kingdom of Ireland created the United Kingdom of Great Britain and Ireland.
Five-sixths of Ireland seceded from the UK in 1922, leaving the present formulation of the United Kingdom of Great Britain and Northern Ireland. There are fourteen British Overseas Territories, the remnants of the British Empire which, at its height in the 1920s, encompassed a quarter of the world's land mass and was the largest empire in history. British influence can be observed in the language and political systems of many of its former colonies; the United Kingdom is a developed country and has the world's fifth-largest economy by nominal GDP and ninth-largest economy by purchasing power parity. It has a high-income economy and has a high Human Development Index rating, ranking 14th in the world, it was the world's first industrialised country and the world's foremost power during the 19th and early 20th centuries. The UK remains a great power, with considerable economic, military and political influence internationally, it is sixth in military expenditure in the world. It has been a permanent member of the United Nations Security Council since its first session in 1946.
It has been a leading member state of the European Union and its predecessor, the European Economic Community, since 1973. The United Kingdom is a member of the Commonwealth of Nations, the Council of Europe, the G7, the G20, NATO, the Organisation for Economic Co-operation and Development and the World Trade Organization; the 1707 Acts of Union declared that the kingdoms of England and Scotland were "United into One Kingdom by the Name of Great Britain". The term "United Kingdom" has been used as a description for the former kingdom of Great Britain, although its official name from 1707 to 1800 was "Great Britain"; the Acts of Union 1800 united the kingdom of Great Britain and the kingdom of Ireland in 1801, forming the United Kingdom of Great Britain and Ireland. Following the partition of Ireland and the independence of the Irish Free State in 1922, which left Northern Ireland as the only part of the island of Ireland within the United Kingdom, the name was changed to the "United Kingdom of Great Britain and Northern Ireland".
Although the United Kingdom is a sovereign country, Scotland and Northern Ireland are widely referred to as countries. The UK Prime Minister's website has used the phrase "countries within a country" to describe the United Kingdom; some statistical summaries, such as those for the twelve NUTS 1 regions of the United Kingdom refer to Scotland and Northern Ireland as "regions". Northern Ireland is referred to as a "province". With regard to Northern Ireland, the descriptive name used "can be controversial, with the choice revealing one's political preferences"; the term "Great Britain" conventionally refers to the island of Great Britain, or politically to England and Wales in combination. However, it is sometimes used as a loose synonym for the United Kingdom as a whole; the term "Britain" is used both as a synonym for Great Britain, as a synonym for the United Kingdom. Usage is mixed, with the BBC preferring to use Britain as shorthand only for Great Britain and the UK Government, while accepting that both terms refer to the United K
In computing, a process is the instance of a computer program, being executed. It contains its activity. Depending on the operating system, a process may be made up of multiple threads of execution that execute instructions concurrently. While a computer program is a passive collection of instructions, a process is the actual execution of those instructions. Several processes may be associated with the same program. Multitasking is a method to allow multiple processes to other system resources; each CPU executes a single task at a time. However, multitasking allows each processor to switch between tasks that are being executed without having to wait for each task to finish. Depending on the operating system implementation, switches could be performed when tasks perform input/output operations, when a task indicates that it can be switched, or on hardware interrupts. A common form of multitasking is time-sharing. Time-sharing is a method to allow high responsiveness for interactive user applications.
In time-sharing systems, context switches are performed which makes it seem like multiple processes are being executed on the same processor. This seeming execution of multiple processes is called concurrency. For security and reliability, most modern operating systems prevent direct communication between independent processes, providing mediated and controlled inter-process communication functionality. In general, a computer system process consists of the following resources: An image of the executable machine code associated with a program. Memory. Operating system descriptors of resources that are allocated to the process, such as file descriptors or handles, data sources and sinks. Security attributes, such as the process' set of permissions. Processor state, such as the content of registers and physical memory addressing; the state is stored in computer registers when the process is executing, in memory otherwise. The operating system holds most of this information about active processes in data structures called process control blocks.
Any subset of the resources at least the processor state, may be associated with each of the process' threads in operating systems that support threads or child processes. The operating system keeps its processes separate and allocates the resources they need, so that they are less to interfere with each other and cause system failures; the operating system may provide mechanisms for inter-process communication to enable processes to interact in safe and predictable ways. A multitasking operating system may just switch between processes to give the appearance of many processes executing though in fact only one process can be executing at any one time on a single CPU, it is usual to associate a single process with a main program, child processes with any spin-off, parallel processes, which behave like asynchronous subroutines. A process is said to own resources. However, in multiprocessing systems many processes may run off of, or share, the same reentrant program at the same location in memory, but each process is said to own its own image of the program.
Processes are called "tasks" in embedded operating systems. The sense of "process" is "something that takes up time", as opposed to "memory", "something that takes up space"; the above description applies to both processes managed by an operating system, processes as defined by process calculi. If a process requests something for which it must wait, it will be blocked; when the process is in the blocked state, it is eligible for swapping to disk, but this is transparent in a virtual memory system, where regions of a process's memory may be on disk and not in main memory at any time. Note that portions of active processes/tasks are eligible for swapping to disk, if the portions have not been used recently. Not all parts of an executing program and its data have to be in physical memory for the associated process to be active. An operating system kernel that allows multitasking needs processes to have certain states. Names for these states are not standardised. First, the process is "created" by being loaded from a secondary storage device into main memory.
After that the process scheduler assigns it the "waiting" state. While the process is "waiting", it waits for the scheduler to do a so-called context switch and load the process into the processor; the process state becomes "running", the processor executes the process instructions. If a process needs to wait for a resource, it is assigned the "blocked" state; the process state is changed back to "waiting". Once the process finishes execution, or is terminated by the operating system, it is no longer needed; the process is removed or is moved to the "terminated" state. When removed, it just waits to be removed from main
A task manager is a system monitor program used to provide information about the processes and applications running on a computer, as well as the general status of the computer. Some implementations can be used to terminate processes and applications, as well as change the processes' scheduling priority. In some environments, users can access a task manager with the Control-Alt-Delete keyboard shortcut. Task managers can display running services as well as those, they can display information about the services, including their process identifier and group identifier.

San Jose, California
San Jose the City of San José, is an economic and political center of Silicon Valley, the largest city in Northern California. With an estimated 2017 population of 1,035,317, it is the third-most populous city in California and the tenth-most populous in United States. Located in the center of the Santa Clara Valley, on the southern shore of San Francisco Bay, San Jose covers an area of 179.97 square miles. San Jose is the county seat of Santa Clara County, the most affluent county in California and one of the most affluent counties in the United States. San Jose is the most populous city in both the San Francisco Bay Area and the San Jose-San Francisco-Oakland Combined Statistical Area, which contain 7.7 million and 8.7 million people respectively. San Jose is a global city, notable as a center of innovation, for its affluence, Mediterranean climate, high cost of living. San Jose's location within the booming high tech industry, as a cultural and economic center has earned the city the nickname "Capital of Silicon Valley".
San Jose is one of the wealthiest major cities in the United States and the world, has the third highest GDP per capita in the world, according to the Brookings Institution. The San Jose Metropolitan Area has the most millionaires and the most billionaires in the United States per capita. With a median home price of $1,085,000, San Jose has the most expensive housing market in the country and the fifth most expensive housing market in the world, according to the 2017 Demographia International Housing Affordability Survey. Major global tech companies including Cisco Systems, eBay, Adobe Systems, PayPal, Samsung, Hewlett Packard Enterprise, Western Digital maintain their headquarters in San Jose, in the center of Silicon Valley. Before the arrival of the Spanish, the area around San Jose was inhabited by the Tamien nation of the Ohlone peoples of California. San Jose was founded on November 29, 1777, as the Pueblo de San José de Guadalupe, the first city founded in the Californias, it became a part of Mexico in 1821 after the Mexican War of Independence.
Following the American Conquest of California during the Mexican–American War, the territory was ceded to the United States in 1848. After California achieved statehood two years San Jose became the state's first capital. Following World War II, San Jose experienced an economic boom, with a rapid population growth and aggressive annexation of nearby cities and communities carried out in the 1950s and 1960s; the rapid growth of the high-technology and electronics industries further accelerated the transition from an agricultural center to an urbanized metropolitan area. Results of the 1990 U. S. Census indicated that San Jose had surpassed San Francisco as the most populous city in Northern California. By the 1990s, San Jose and the rest of Silicon Valley had become the global center for the high tech and internet industries, making it California's fastest-growing economy; the Santa Clara Valley has been home to the Tamyen group of the Ohlone people since around 4,000 BCE. The Tamyen spoke Tamyen language of the Ohlone language family.
With the Spanish colonization of California, the majority of the Tamyen came to inhabit Mission Santa Clara de Asís and Mission San José. California was claimed as part of the Spanish Empire in 1542, when explorer Juan Rodríguez Cabrillo charted the Californian coast. During this time and Baja California were administered together as Province of the California. For nearly 200 years, the Californias were sparsely populated and ignored by the government of the Viceroyalty of New Spain in Mexico City. Only in 1769 was Northern California surveyed by Spanish authorities, with the Portolá Expedition. In 1776, the Californias were included as part of the Captaincy General of the Provincias Internas, a large administrative division created by José de Gálvez, Spanish Minister of the Indies, in order to provide greater autonomy for the Spanish Empire's populated and ungoverned borderlands; that year, King Carlos III of Spain approved an expedition by Juan Bautista de Anza to survey the San Francisco Bay Area, in order to choose the sites for two future settlements and their accompanying mission.
First he chose the site for a military settlement in San Francisco, for the Royal Presidio of San Francisco, Mission San Francisco de Asís. On his way back to Mexico from San Francisco, de Anza chose the sites in Santa Clara Valley for a civilian settlement, San Jose, on the eastern bank of the Guadalupe River, a mission on its western bank, Mission Santa Clara de Asís. San Jose was founded as California's first civilian settlement on November 29, 1777, as the Pueblo de San José de Guadalupe by José Joaquín Moraga, under orders of Antonio María de Bucareli y Ursúa, Viceroy of New Spain. San Jose served as a strategic settlement along El Camino Real, connecting the military fortifications at the Monterey Presidio and the San Francisco Presidio, as well as the California mission network. In 1791, due to the severe flooding which characterized the pueblo, San Jose's settlement was moved a mile south, centered on the Pueblo Plaza. In 1800, due to the growing population in the northern part of the Californias, Diego de Borica, Governor of the Californias split the province into two parts: Alta California, which would become a U.
S. state, Baja California, which would become two Mexican states. San Jose became part of the First M
Mozilla Firefox is a free and open-source web browser developed by The Mozilla Foundation and its subsidiary, Mozilla Corporation. Firefox is available for Microsoft Windows, macOS, Linux, BSD, illumos and Solaris operating systems, its sibling, Firefox for Android, is available. Firefox uses the Gecko layout engine to render web pages, which implements current and anticipated web standards. In 2017, Firefox began incorporating new technology under the code name Quantum to promote parallelism and a more intuitive user interface. An additional version, Firefox for iOS, was released on November 12, 2015. Due to platform restrictions, it uses the WebKit layout engine instead of Gecko, as with all other iOS web browsers. Firefox was created in 2002 under the codename "Phoenix" by the Mozilla community members who desired a standalone browser, rather than the Mozilla Application Suite bundle. During its beta phase, Firefox proved to be popular with its testers and was praised for its speed and add-ons compared to Microsoft's then-dominant Internet Explorer 6.
Firefox was released on November 9, 2004, challenged Internet Explorer's dominance with 60 million downloads within nine months. Firefox is the spiritual successor of Netscape Navigator, as the Mozilla community was created by Netscape in 1998 before their acquisition by AOL. Firefox usage grew to a peak of 32% at the end of 2009, with version 3.5 overtaking Internet Explorer 7, although not Internet Explorer as a whole. Usage declined in competition with Google Chrome; as of January 2019, Firefox has 9.5% usage share as a "desktop" browser, according to StatCounter, making it the second-most popular such web browser. Firefox is still the most popular desktop browser in a few countries including Cuba and Eritrea with 72.26% and 83.28% of the market share, respectively. According to Mozilla, in December 2014, there were half a billion Firefox users around the world; the project began as an experimental branch of the Mozilla project by Dave Hyatt, Joe Hewitt, Blake Ross. They believed the commercial requirements of Netscape's sponsorship and developer-driven feature creep compromised the utility of the Mozilla browser.
To combat what they saw as the Mozilla Suite's software bloat, they created a stand-alone browser, with which they intended to replace the Mozilla Suite. On April 3, 2003, the Mozilla Organization announced that they planned to change their focus from the Mozilla Suite to Firefox and Thunderbird; the community-driven SeaMonkey was formed and replaced the Mozilla Application Suite in 2005. The Firefox project has undergone several name changes, it was titled Phoenix, which carried the implication of the mythical firebird that rose triumphantly from the ashes of its dead predecessor, in this case from the "ashes" of Netscape Navigator after it had been killed off by Microsoft Internet Explorer in the "First Browser War". Phoenix was renamed due to trademark issues with Phoenix Technologies. In response, the Mozilla Foundation stated that the browser would always bear the name Mozilla Firebird to avoid confusion. After further pressure, on February 9, 2004, Mozilla Firebird became Mozilla Firefox.
The name Firefox was said to be derived from a nickname of the red panda, which became the mascot for the newly named project. For the abbreviation of Firefox, Mozilla prefers Fx or fx, though it is abbreviated as FF; the Firefox project went through many versions before version 1.0 was released on November 9, 2004. In 2016, Mozilla announced a project known as Quantum, which sought to improve Firefox's Gecko engine and other components to improve Firefox's performance, modernize its architecture, transition the browser to a multi-process model; these improvements came in the wake of decreasing market share to Google Chrome, as well as concerns that its performance was lapsing in comparison. Despite its improvements, these changes required existing add-ons for Firefox to be made incompatible with newer versions, in favor of a new extension system, designed to be similar to Chrome and other recent browsers. Firefox 57, released in November 2017, was the first version to contain enhancements from Quantum, has thus been named Firefox Quantum.
Firefox supported add-ons using the XUL and XPCOM APIs, which allowed them to directly access and manipulate much of the browser's internal functionality. As they are not compatible with its m
