Lahore is the capital city of the Pakistani province of Punjab. It is the second most populous city in Pakistan and the 32nd most populous city in the world, the city is located in the north-eastern end of Pakistans Punjab province, near the border with the Indian state of Punjab. Lahore is ranked as a world city, and is one of Pakistans wealthiest cities with an estimated GDP of $58.14 billion as of 2014. Lahore is the cultural centre of the Punjab region, and is the largest Punjabi city in the world. The city has a history, and was once under the rule of the Hindu Shahis, Ghaznavids, Ghurids. Lahore reached the height of its splendour under the Mughal Empire, the city was contested between the Maratha Empire and Durrani Empire, then became capital of the Sikh Empire, before becoming the capital of the Punjab under British rule. Following the independence of Pakistan in 1947, Lahore became the capital of Pakistans Punjab province, Lahore is one of Pakistans most liberal and cosmopolitan cities. It exerts a strong influence over Pakistan. Lahore is a centre for Pakistans publishing industry, and remains the foremost centre of Pakistans literary scene. The city is also a centre of education in Pakistan. Lahore is also home to Pakistans film industry, Lollywood, and is a centre of Qawwali music. The city is much of Pakistans tourist industry, with major attractions including the old Walled City. Lahore is also home to the UNESCO World Heritage Sites of Lahore Fort, the etymology of Lahore is uncertain, but according to legend the city was once known as Lavapura, in honour of Prince Lava of the Hindu epic poem, the Ramayana. Lahore Fort also contains a vacant Lava temple, dedicated to the founder of the city. Lahore was called by different names throughout history, to date there is no conclusive evidence as to when it was founded. Lahore is described as a Hindu principality in the Rajput accounts, keneksen, the founder of Suryavansha, is believed to have migrated out from the city. The Solanki tribe, belonging to Amukhara Pattan, which included the Bhatti Rajputs of Jaisalmer, Lahore appears as the capital of the Punjab for the first time under Anandapala – the Hindu Shahi king who is referred to as the ruler of –after leaving the earlier capital of Waihind. Few references to Lahore remain from before its capture by Sultan Mahmud of Ghaznavi in the 11th century, the sultan took Lahore after a long siege and battle in which the city was torched and depopulated

Pakistan
–
Pakistan, officially the Islamic Republic of Pakistan, is a federal parliamentary republic in South Asia on the crossroads of Central Asia and Western Asia. It is the sixth-most populous country with a population exceeding 200 million people, in terms of area, it is the 33rd-largest country in the world with an area covering 881,913 square kilometres. It is separated from Tajikistan by Afghanistans narrow Wakhan Corridor in the north, Pakistan is unique among Muslim countries in that it is the only country to have been created in the name of Islam. As a result of the Pakistan Movement led by Muhammad Ali Jinnah and it is an ethnically and linguistically diverse country, with a similarly diverse geography and wildlife. Initially a dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic, an ethnic civil war in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh. The new constitution stipulated that all laws were to conform to the injunctions of Islam as laid down in the Quran. Pakistan has an economy with a well-integrated agriculture sector. The Pakistani economy is the 24th-largest in the world in terms of purchasing power and it is ranked among the emerging and growth-leading economies of the world, and is backed by one of the worlds largest and fastest-growing middle classes. The post-independence history of Pakistan has been characterised by periods of military rule, the country continues to face challenging problems such as illiteracy, healthcare, and corruption, but has substantially reduced poverty and terrorism and expanded per capita income. It is also a member of CERN. Pakistan is a signatory to the Kyoto Protocol, the Paris Agreement, the name Pakistan literally means land of the pure in Urdu and Persian. It is a play on the word pāk meaning pure in Persian and Pashto, the letter i was incorporated to ease pronunciation and form the linguistically correct and meaningful name. Some of the earliest ancient human civilisations in South Asia originated from areas encompassing present-day Pakistan, the earliest known inhabitants in the region were Soanian during the Lower Paleolithic, of whom stone tools have been found in the Soan Valley of Punjab. The Vedic Civilization, characterised by Indo-Aryan culture, laid the foundations of Hinduism, Multan was an important Hindu pilgrimage centre. The Vedic civilisation flourished in the ancient Gandhāran city of Takṣaśilā, the Indo-Greek Kingdom founded by Demetrius of Bactria included Gandhara and Punjab and reached its greatest extent under Menander, prospering the Greco-Buddhist culture in the region. Taxila had one of the earliest universities and centres of education in the world. At its zenith, the Rai Dynasty of Sindh ruled this region, the Pala Dynasty was the last Buddhist empire, which, under Dharampala and Devapala, stretched across South Asia from what is now Bangladesh through Northern India to Pakistan. The Arab conqueror Muhammad bin Qasim conquered the Indus valley from Sindh to Multan in southern Punjab in 711 AD, the Pakistan governments official chronology identifies this as the time when the foundation of Pakistan was laid

Floppy disk
–
Floppy disks are read and written by a floppy disk drive. Floppy disks, initially as 8-inch media and later in 5¼-inch and 3½-inch sizes, were a form of data storage and exchange from the mid-1970s into the mid-2000s. These formats are usually handled by older equipment and these disks and associated drives were produced and improved upon by IBM and other companies such as Memorex, Shugart Associates, and Burroughs Corporation. The term floppy disk appeared in print as early as 1970, in 1976, Shugart Associates introduced the first 5¼-inch FDD. By 1978 there were more than 10 manufacturers producing such FDDs, there were competing floppy disk formats, with hard- and soft-sector versions and encoding schemes such as FM, MFM and GCR. The 5¼-inch format displaced the 8-inch one for most applications, the most common capacity of the 5¼-inch format in DOS-based PCs was 360 kB and in 1984 IBM introduced the 1.2 MB dual-sided floppy disk along with its PC-AT model. IBM started using the 720 kB double-density 3½-inch microfloppy disk on its Convertible laptop computer in 1986 and these disk drives could be added to older PC models. In 1988 IBM introduced a drive for 2.88 MB DSED diskettes in its top-of-the-line PS/2 models, throughout the early 1980s, limitations of the 5¼-inch format became clear. Originally designed to be practical than the 8-inch format, it was itself too large, as the quality of recording media grew. A number of solutions were developed, with drives at 2-, 2½-, 3-, 3½-, the large market share of the 5¼-inch format made it difficult for these new formats to gain significant market share. A variant on the Sony design, introduced in 1982 by a number of manufacturers, was then rapidly adopted. By the end of the 1980s, 5¼-inch disks had been superseded by 3½-inch disks, by the mid-1990s, 5¼-inch drives had virtually disappeared, as the 3½-inch disk became the predominant floppy disk. Floppy disks became ubiquitous during the 1980s and 1990s in their use with computers to distribute software, transfer data. Before hard disks became affordable to the population, floppy disks were often used to store a computers operating system. Most home computers from that period have a primary OS and BASIC stored as ROM, by the early 1990s, the increasing software size meant large packages like Windows or Adobe Photoshop required a dozen disks or more. In 1996, there were a five billion standard floppy disks in use. Then, distribution of packages was gradually replaced by CD-ROMs, DVDs. External USB-based floppy disk drives are available, many modern systems provide firmware support for booting from such drives

Lahore Junction railway station is the central railway station in Lahore, Punjab, Pakistan. It is situated at the convergence of Empress Road, Allama Iqbal Road, the station building is owned by Pakistan Railways and also serves as its headquarters. Lahore Junction station was constructed by Mian Mohammad Sultan Chughtai, an official of the Mughal Empire. The station served as the headquarters for the Punjab Railway and later would serve as the terminus of the Scinde, Punjab & Delhi Railway. It remains a legacy of the extensive railway network established during the British Raj. The station was affected during the riots which followed the Partition of the British Indian Empire. Similar to the situation with migrating Muslims from Delhi, Lahores Hindus.

Hard disk drive
–
The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a manner, meaning that individual blocks of data can be stored or retrieved in any order. HDDs are a type of storage, retaining stored data even when powered off. Introduced by IBM in 1956, HDDs became the dominant secondary storage device for computers by the early 1960s. Continuously improved, HDDs have maintained this position into the era of servers. More than 200 companies have produced HDDs historically, though after extensive industry consolidation most current units are manufactured by Seagate, Toshiba, as of 2016, HDD production is growing, although unit shipments and sales revenues are declining. While SSDs have higher cost per bit, SSDs are replacing HDDs where speed, power consumption, small size, the primary characteristics of an HDD are its capacity and performance. Capacity is specified in unit prefixes corresponding to powers of 1000, the two most common form factors for modern HDDs are 3. 5-inch, for desktop computers, and 2. 5-inch, primarily for laptops. HDDs are connected to systems by standard interface cables such as PATA, SATA, Hard disk drives were introduced in 1956, as data storage for an IBM real-time transaction processing computer and were developed for use with general-purpose mainframe and minicomputers. The first IBM drive, the 350 RAMAC in 1956, was approximately the size of two medium-sized refrigerators and stored five million six-bit characters on a stack of 50 disks. In 1962 the IBM350 RAMAC disk storage unit was superseded by the IBM1301 disk storage unit, cylinder-mode read/write operations were supported, and the heads flew about 250 micro-inches above the platter surface. Motion of the head array depended upon a binary system of hydraulic actuators which assured repeatable positioning. The 1301 cabinet was about the size of three home refrigerators placed side by side, storing the equivalent of about 21 million eight-bit bytes, access time was about a quarter of a second. Also in 1962, IBM introduced the model 1311 disk drive, users could buy additional packs and interchange them as needed, much like reels of magnetic tape. Later models of removable pack drives, from IBM and others, became the norm in most computer installations, non-removable HDDs were called fixed disk drives. Some high-performance HDDs were manufactured with one head per track so that no time was lost physically moving the heads to a track, known as fixed-head or head-per-track disk drives they were very expensive and are no longer in production. In 1973, IBM introduced a new type of HDD code-named Winchester and its primary distinguishing feature was that the disk heads were not withdrawn completely from the stack of disk platters when the drive was powered down. Instead, the heads were allowed to land on an area of the disk surface upon spin-down

European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations.

TED (conference)
–
TED is a media organization which posts talks online for free distribution, under the slogan ideas worth spreading. TED was founded in February 1984 as a conference, which has been held annually since 1990. TEDs early emphasis was technology and design, consistent with its Silicon Valley origins, but it has broadened its focus to include talks on many scientific, cultural. The main TED conference is held annually in Vancouver, British Columbia, prior to 2014, the conference was held in Long Beach. TED events are held throughout North America and in Europe and Asia. They address a range of topics within the research and practice of science and culture. The speakers are given a maximum of 18 minutes to present their ideas in the most innovative, TEDs current curator is the British former computer journalist and magazine publisher Chris Anderson. Since June 2006, TED Talks have been offered for free viewing online, under an Attribution-NonCommercial-NoDerivatives Creative Commons license, as of March 2016, over 2,400 TED Talks are freely available on the website. In June 2011, TED Talks combined viewing figure stood at more than 500 million, not all TED Talks are equally popular, however. Those given by academics tend to be watched more online while art, TED was conceived in 1984 by architect and graphic designer Richard Saul Wurman, who observed a convergence of the fields of technology, entertainment, and design. Presentations were given by famous mathematician Benoit Mandelbrot and influential members of the community, like Nicholas Negroponte. The event was unsuccessful, it took six years before the second conference was organized. In 2000, Wurman, looking for a successor at age 65, met with new-media entrepreneur, Andersons UK media company Future bought TED. And in November 2001, Andersons non-profit The Sapling Foundation acquired TED from Future for £6m, in February 2002, Anderson gave a TED Talk in which he explained his vision of the conference and his future role of curator. Wurman left after the 2002 conference, in 2006, attendance cost was $4,400 per person and was by invitation only. The membership model was shifted in January 2007 to a membership fee of $6,000, which includes attendance of the conference, club mailings, networking tools. The 2017 conference will be $8,500 per attendee, in 2014, the conference was relocated to Vancouver. TED is currently funded by a combination of revenue streams, including conference attendance fees, corporate sponsorships, foundation support, licensing fees

Computer virus
–
A computer virus is a type of malicious software program that, when executed, replicates by reproducing itself or infecting other computer programs by modifying them. Infecting computer programs can include as well, data files, or the sector of the hard drive. When this replication succeeds, the areas are then said to be infected with a computer virus. The term virus is also commonly, but erroneously, used to refer to types of malware. The majority of active malware threats are actually trojan horse programs or computer worms rather than computer viruses, the term computer virus, coined by Fred Cohen in 1985, is a misnomer. Virus writers use social engineering deceptions and exploit detailed knowledge of security vulnerabilities to gain access to their hosts computers and computing resources. Computer viruses currently cause billions of dollars worth of damage each year, due to causing system failure, wasting computer resources, corrupting data, increasing maintenance costs. The work of von Neumann was later published as the Theory of self-reproducing automata, in his essay von Neumann described how a computer program could be designed to reproduce itself. Von Neumanns design for a computer program is considered the worlds first computer virus. In 1972, Veith Risak, directly building on von Neumanns work on self-replication, the article describes a fully functional virus written in assembler programming language for a SIEMENS 4004/35 computer system. In 1980 Jürgen Kraus wrote his diplom thesis Selbstreproduktion bei Programmen at the University of Dortmund, in his work Kraus postulated that computer programs can behave in a way similar to biological viruses. The Creeper virus was first detected on ARPANET, the forerunner of the Internet, Creeper was an experimental self-replicating program written by Bob Thomas at BBN Technologies in 1971. Creeper used the ARPANET to infect DEC PDP-10 computers running the TENEX operating system, Creeper gained access via the ARPANET and copied itself to the remote system where the message, Im the creeper, catch me if you can. The Reaper program was created to delete Creeper, in fiction, the 1973 Michael Crichton sci-fi movie Westworld made an early mention of the concept of a computer virus, being a central plot theme that causes androids to run amok. Alan Oppenheimers character summarizes the problem by stating that. theres a pattern here which suggests an analogy to an infectious disease process. To which the replies are stated, Perhaps there are similarities to disease and. In 1982, a program called Elk Cloner was the first personal computer virus to appear in the wild—that is, outside the single computer or lab where it was created. Written in 1981 by Richard Skrenta while in the grade at Mount Lebanon High School near Pittsburgh, it attached itself to the Apple DOS3.3 operating system
