Urdu Keyboard
The Urdu keyboard is any keyboard layout for Urdu computer and typewriter keyboards. Since the first Urdu typewriter was made available in 1911, the layout has gone through various phases of evolution.Zia (1999a) With time, the variety of layouts introduced in the 1950s for mechanized compositions have reduced to very few that are compatible with the new digital age. Modern improvements in Urdu keyboard were pioneered by the National Language Authority () in Pakistan, which standardized the linguistic aspects such as orthography and lexicography. These developments helped the keyboard layout to evolve from the typewriters to be compatible with computers, to increase the productivity and textual efficiency of the language, especially through modern electronic media. Evolution of the Urdu keyboard When Urdu was declared as the national language of the independent Pakistan in 1947, a variety of keyboard designs were quickly brought into the market by various individuals and organiza ...

Consonant
In articulatory phonetics, a consonant is a speech sound that is articulated with complete or partial closure of the vocal tract, except for the h sound, which is pronounced without any stricture in the vocal tract. Examples are and [b], pronounced with the lips; and [d], pronounced with the front of the tongue; and [g], pronounced with the back of the tongue; , pronounced throughout the vocal tract; , [v], , and [z] pronounced by forcing air through a narrow channel (fricatives); and and , which have air flowing through the nose (nasal consonant, nasals). Most consonants are Pulmonic consonant, pulmonic, using air pressure from the lungs to generate a sound. Very few natural languages are non-pulmonic, making use of Ejective consonant, ejectives, Implosive consonant, implosives, and Click consonant, clicks. Contrasting with consonants are vowels. Since the number of speech sounds in the world's languages is much greater than the number of letters in any one alphabet, Linguis ...

Nasta'liq Script
''Nastaliq'' (; ; ), also romanized as ''Nastaʿlīq'' or ''Nastaleeq'' (), is one of the main calligraphic hands used to write Arabic script and is used for some Indo-Iranian languages, predominantly Classical Persian, Kashmiri, Punjabi and Urdu. It is often used also for Ottoman Turkish poetry, but rarely for Arabic. ''Nastaliq'' developed in Iran from '' naskh'' beginning in the 13th century and remains widely used in Iran, India, Afghanistan, Pakistan, and other countries for written poetry and as a form of art. History The name ''Nastaliq'' "is a contraction of the Persian (), meaning a hanging or suspended '' naskh.''" Virtually all Safavid authors (like Dust Muhammad or Qadi Ahmad) attributed the invention of to Mir Ali Tabrizi, who lived at the end of the 14th and the beginning of the 15th century. That tradition was questioned by Elaine Wright, who traced the evolution of ''Nastaliq'' in 14th-century Iran and showed how it developed gradually among scribes in ...

Unicode
Unicode or ''The Unicode Standard'' or TUS is a character encoding standard maintained by the Unicode Consortium designed to support the use of text in all of the world's writing systems that can be digitized. Version 16.0 defines 154,998 Character (computing), characters and 168 script (Unicode), scripts used in various ordinary, literary, academic, and technical contexts. Unicode has largely supplanted the previous environment of a myriad of incompatible character sets used within different locales and on different computer architectures. The entire repertoire of these sets, plus many additional characters, were merged into the single Unicode set. Unicode is used to encode the vast majority of text on the Internet, including most web pages, and relevant Unicode support has become a common consideration in contemporary software development. Unicode is ultimately capable of encoding more than 1.1 million characters. The Unicode character repertoire is synchronized with Univers ...

Character Encoding
Character encoding is the process of assigning numbers to graphical character (computing), characters, especially the written characters of human language, allowing them to be stored, transmitted, and transformed using computers. The numerical values that make up a character encoding are known as code points and collectively comprise a code space or a code page. Early character encodings that originated with optical or electrical telegraphy and in early computers could only represent a subset of the characters used in written languages, sometimes restricted to Letter case, upper case letters, Numeral system, numerals and some punctuation only. Over time, character encodings capable of representing more characters were created, such as ASCII, the ISO/IEC 8859 encodings, various computer vendor encodings, and Unicode encodings such as UTF-8 and UTF-16. The Popularity of text encodings, most popular character encoding on the World Wide Web is UTF-8, which is used in 98.2% of surve ...

Software
Software consists of computer programs that instruct the Execution (computing), execution of a computer. Software also includes design documents and specifications. The history of software is closely tied to the development of digital computers in the mid-20th century. Early programs were written in the machine language specific to the hardware. The introduction of high-level programming languages in 1958 allowed for more human-readable instructions, making software development easier and more portable across different computer architectures. Software in a programming language is run through a compiler or Interpreter (computing), interpreter to execution (computing), execute on the architecture's hardware. Over time, software has become complex, owing to developments in Computer network, networking, operating systems, and databases. Software can generally be categorized into two main types: # operating systems, which manage hardware resources and provide services for applicat ...

Numerical Digit
A numerical digit (often shortened to just digit) or numeral is a single symbol used alone (such as "1"), or in combinations (such as "15"), to represent numbers in positional notation, such as the common base 10. The name "digit" originates from the Latin ''digiti'' meaning fingers. For any numeral system with an integer base, the number of different digits required is the absolute value of the base. For example, decimal (base 10) requires ten digits (0 to 9), and binary (base 2) requires only two digits (0 and 1). Bases greater than 10 require more than 10 digits, for instance hexadecimal (base 16) requires 16 digits (usually 0 to 9 and A to F). Overview In a basic digital system, a numeral is a sequence of digits, which may be of arbitrary length. Each position in the sequence has a place value, and each digit has a value. The value of the numeral is computed by multiplying each digit in the sequence by its place value, and summing the results. Di ...

Arithmetic
Arithmetic is an elementary branch of mathematics that deals with numerical operations like addition, subtraction, multiplication, and division. In a wider sense, it also includes exponentiation, extraction of roots, and taking logarithms. Arithmetic systems can be distinguished based on the type of numbers they operate on. Integer arithmetic is about calculations with positive and negative integers. Rational number arithmetic involves operations on fractions of integers. Real number arithmetic is about calculations with real numbers, which include both rational and irrational numbers. Another distinction is based on the numeral system employed to perform calculations. Decimal arithmetic is the most common. It uses the basic numerals from 0 to 9 and their combinations to express numbers. Binary arithmetic, by contrast, is used by most computers and represents numbers as combinations of the basic numerals 0 and 1. Computer arithmetic deals with the specificities of the ...
