Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, Google has further developed Android TV for televisions, Android Auto for cars, and Android Wear for wrist watches, each with a specialized user interface. Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics.
Android has the largest installed base of all operating systems (OS) of any kind.Android has been the best selling OS on tablets since 2013, and on smartphones it is dominant by any metric.
Initially developed by Android, Inc., which Google bought in 2005,Android was unveiled in 2007 along with the founding of the Open Handset Alliance – a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices.As of July 2013, the Google Play store has had over one million Android applications ("apps") published – including many "business-class apps"that rival competing mobile platforms – and over 50 billion applications downloaded.An April–May 2013 survey of mobile application developers found that 71% of developers create applications for Android,and a 2015 survey found that 40% of full-time professional developers see Android as their priority target platform, which is comparable to Apple's iOS on 37% with both platforms far above others.In September 2015, Android had 1.4 billion monthly active devices.
Android's source code is released by Google under open source licenses, although most Android devices ultimately ship with a combination of open source and proprietary software, including proprietary software required for accessing Google services.Android is popular with technology companies that require a ready-made, low-cost and customizable operating system for high-tech devices.Its open nature has encouraged a large community of developers and enthusiasts to use the open-source code as a foundation for community-driven projects, which deliver updates to older devices, add new features for advanced users or bring Android to devices originally shipped with other operating systems. The success of Android has made it a target for patent (and copyright) litigation as part of the so-called "smartphone wars" between technology companies.

Visual programming (pemrograman visual) adalah pendekatan dalam pemrograman komputer yang memungkinkan pengguna untuk membuat program melalui antarmuka grafis yang intuitif dan mudah digunakan. Dalam pemrograman visual, pengguna menggambar diagram atau ikon yang merepresentasikan operasi atau fungsi yang ingin dilakukan oleh program, lalu menghubungkannya dengan garis atau panah untuk membentuk alur logika.
Pemrograman visual memiliki beberapa keuntungan dibandingkan dengan pemrograman teks tradisional. Pertama, pemrograman visual lebih mudah dipelajari oleh pemula karena antarmuka grafis yang intuitif. Kedua, pemrograman visual dapat membantu pengguna memvisualisasikan alur program secara keseluruhan, sehingga memudahkan pengguna untuk memahami bagaimana program bekerja. Ketiga, pemrograman visual dapat mempercepat proses pengembangan program karena menghilangkan kebutuhan untuk mengetik kode secara manual.
Contoh dari bahasa pemrograman visual termasuk Scratch, Blockly, dan LabVIEW.
Have you ever wondered why learning a programming language is necessary or why individuals choose to do so? All Internet services we use today are the result of programming languages.
A programming language is a way of communication between programmers/developers and computers. A set of rules called a programming language enables the conversion of textual values into different ways of creating machine code, or in the case of visually programming languages, graphical components.
Remember your first glance at a screenful of computer code? It probably felt like reading another language. Some words may have looked familiar, such as “print” and “input,” but they were surrounded by symbols and numbers that looked completely new.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
