What is CSS ?

CSS (Cascading Style Sheets)

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation of a document written in a markup language like HTML. CSS is a cornerstone technology of the World Wide Web, alongside HTML and JavaScript.

CSS is designed to enable the separation of presentation and content, including layout, colors, and fonts. This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple web pages to share formatting by specifying the relevant CSS in a separate .css file, and reduce complexity and repetition in the structural content.

Separation of formatting and content also makes it feasible to present the same markup page in different styles for different rendering methods, such as on-screen, in print, by voice (via speech-based browser or screen reader), and on Braille-based tactile devices. CSS also has rules for alternate formatting if the content is accessed on a mobile device.

The name cascading comes from the specified priority scheme to determine which style rule applies if more than one rule matches a particular element. This cascading priority scheme is predictable.

What is HTML?

HTML ( HyperText Markup Language )

HTML is a computer language devised to allow website creation. These websites can then be viewed by anyone else connected to the Internet. It is relatively easy to learn, with the basics being accessible to most people in one sitting; and quite powerful in what it allows you to create. It is constantly undergoing revision and evolution to meet the demands and requirements of the growing Internet audience under the direction of the » W3C, the organisation charged with designing and maintaining the language.

The definition of HTML is HyperText Markup Language.

• HyperText is the method by which you move around on the web — by clicking on special text called hyperlinks which bring you to the next page. The fact that it is hyper just means it is not linear — i.e. you can go to any place on the Internet whenever you want by clicking on links — there is no set order to do things in.
• Markup is what HTML tags do to the text inside them. They mark it as a certain type of text (italicised text, for example).
• HTML is a Language, as it has code-words and syntax like any other language.

What is Java Language ?

Java Language

Java is a computer programming language. It enables programmers to write computer instructions using English-based commands instead of having to write in numeric codes. It’s known as a high-level language because it can be read and written easily by humans.

Like English, Java has a set of rules that determine how the instructions are written. These rules are known as its syntax. Once a program has been written, the high-level instructions are translated into numeric codes that computers can understand and execute.

Who is James Gosling ?

James A. Gosling, O.C., Ph.D. (born May 19, 1955 near Calgary, Alberta, Canada) is a famous software developer, best known as the father of the Java programming language.

In 1977, James Gosling received a B.Sc in Computer Science from the University of Calgary. In 1983, he earned a Ph.D in Computer Science from Carnegie Mellon University, and his doctoral thesis was titled "The Algebraic Manipulation of Constraints". While working towards his doctorate, he wrote a version of emacs (gosmacs), and before joining Sun Microsystems he built a multi-processor version of Unix[1] while at Carnegie Mellon University, as well as several compilers and mail systems.

Since 1984, Gosling has been with Sun Microsystems, and is generally known best as the founder of the Java programming language.

He is generally credited as the inventor of the Java programming language in 1991. He did the original design of Java and implemented its original compiler and virtual machine. For this achievement he was elected to the United States National Academy of Engineering. He has also made major contributions to several other software systems, such as NeWS and Gosling Emacs. He also cowrote the "bundle" program, a utility thoroughly detailed in Brian Kernighan and Rob Pike's book The Unix Programming Environment.

What is C language ?

C Language

C is a high-level and general-purpose programming language that is ideal for developing firmware or portable applications. Originally intended for writing system software, C was developed at Bell Labs by Dennis Ritchie for the Unix Operating System in the early 1970s.

Ranked among the most widely used languages, C has a compiler for most computer systems and has influenced many popular languages – notably C++.

Who is Dennis Ritchie ?

Dennis MacAlistair Ritchie (September 9, 1941 – October 12, 2011), commonly known by his username dmr, was an American computer scientist who "helped shape the digital era." He created the C programming language and, with long-time colleague, Ken Thompson, the UNIX operating system. Ritchie and Thompson received the Turing Award from the ACM in 1983, the Hamming Medal from the IEEE in 1990 and the National Medal of Technology from President Clinton in 1999. Ritchie was the head of Lucent Technologies System Software Research Department when he retired in 2007. The 'R' of the K&R C book stands for his name.

Ritchie was best known as the creator of the C programming language, a key developer of the UNIX operating system, and co-author of The C Programming Language, commonly referred to as K&R (in reference to the authors Kernighan and Ritchie). Ritchie worked together with Ken Thompson, the scientist credited with writing the original Unix; one of Ritchie's most important contributions to Unix was its porting to different machines and platforms.

The C language is widely used today in application, operating system, and embedded system development, and its influence is seen in most modern programming languages. UNIX has also been influential, establishing concepts and principles that are now precepts of computing.

Ritchie was elected to the National Academy of Engineering in 1988 for "development of the "C" programming language and for co-development of the UNIX operating system.

What is C plus plus ( C++ ) Language ?

C++ Language

is a general-purpose object-oriented programming (OOP) language, developed by Bjarne Stroustrup, and is an extension of the C language. It is therefore possible to code C++ in a "C style" or "object-oriented style.“, c++ is considered to be an intermediate-level language, as it encapsulates both high- and low-level language features. Initially, the language was called "C with classes" as it had all the properties of the C language with an additional concept of "classes."

C++ is one of the most popular languages primarily utilized with system/application software, drivers, client-server applications and embedded firmware.

Who is Bjarne Stroustrup ?

Bjarne Stroustrup was born in Aarhus, Denmark, in 1950. He received a master's in mathematics from Aarhus University in 1975 and a PhD in computer science from Cambridge University in 1979.

Stroustrup then joined Bell Labs' Computer Science Research Center in Murray Hill, New Jersey, where he designed and implemented C++. This language, based on C and inspired by Simula, provides a set of general and flexible abstraction mechanisms that can be mapped directly and efficiently onto computer hardware. C++ revolutionized the software industry by enabling a variety of software development techniques-including object-oriented programming, generic programming, and general resource management-to be deployed at scale. For more than two decades, C++ has been among the most widely used programming languages, with applications in areas including general systems programming, communications, computer graphics, games, user-interfaces, embedded systems, financial systems, avionics, and scientific computation. The influence of C++ and the ideas it pioneered and popularized are clearly visible far beyond the C++ community.

Over the next decades, Stroustrup guided the further evolution of C++ through his involvement in its ISO standards effort, his books, and his many academic and popular papers.

Stroustrup is a managing director in the technology division of Morgan Stanley in New York City, a visiting professor at Columbia University, and a Distinguished Research Professor at Texas A&M University (where he taught for a decade). His research interests include design, programming techniques, distributed systems, performance, reliability, and maintainability.

His honors include: ACM's Grace Murray Hopper Award (1993), member of the US National Academy of Engineering (2004), Sigma Xi's William Procter Prize for Scientific Achievement (2005), and Aarhus University's Rigmor og Carl Holst-Knudsens Videnskapspris (2010). He is a Fellow of IEEE and ACM.

What is Bitcoin ( The Most Expensive Currency In The World !!! )

What is Bitcoin ?

To slice through a portion of the disarray encompassing Bitcoin, we have to isolate it into two segments. From one viewpoint, you have Bitcoin-the-token, a scrap of code that speaks to responsibility for advanced idea – similar to a virtual IOU. Then again, you have Bitcoin-the-convention, a conveyed system that keeps up a record of equalizations of Bitcoin-the-token. Both are alluded to as "Bitcoin." 

The system enables payments to be sent between users without passing through a central authority, for example, a bank or installment portal. It is made and held electronically. Bitcoins aren't printed, similar to dollars or euros – they're delivered by PCs all around the globe, utilizing free programming. 

It was the main case of what we today call Cryptocurrencies, a developing resource class that shares a few attributes of customary monetary standards, with check dependent on cryptography.

Who created it?

A pseudonymous software developer going by the name of Satoshi Nakamoto proposed Bitcoin in 2008, as an electronic payment system based on mathematical proof. The idea was to produce a means of exchange, independent of any central authority, that could be transferred electronically in a secure, verifiable and immutable way.

To this day, no-one knows who Satoshi Nakamoto really is.

In what ways is it different from traditional currencies?

Bitcoin can be used to pay for things electronically, if both parties are willing. In that sense, it’s like conventional dollars, euros, or yen, which are also traded digitally.

But it differs from fiat digital currencies in several important ways:

1 – Decentralization

Bitcoin’s most important characteristic is that it is decentralized. No single institution controls the bitcoin network. It is maintained by a group of volunteer coders, and run by an open network of dedicated computers spread around the world. This attracts individuals and groups that are uncomfortable with the control that banks or government institutions have over their money.

Bitcoin solves the “double spending problem” of electronic currencies (in which digital assets can easily be copied and re-used) through an ingenious combination of cryptography and economic incentives. In electronic fiat currencies, this function is fulfilled by banks, which gives them control over the traditional system. With bitcoin, the integrity of the transactions is maintained by a distributed and open network, owned by no-one.

2 – Limited supply

Fiat currencies (dollars, euros, yen, etc.) have an unlimited supply – central banks can issue as many as they want, and can attempt to manipulate a currency’s value relative to others. Holders of the currency (and especially citizens with little alternative) bear the cost.

With bitcoin, on the other hand, the supply is tightly controlled by the underlying algorithm. A small number of new bitcoins trickle out every hour, and will continue to do so at a diminishing rate until a maximum of 21 million has been reached. This makes bitcoin more attractive as an asset – in theory, if demand grows and the supply remains the same, the value will increase.

3 – Pseudonymity

While senders of traditional electronic payments are usually identified (for verification purposes, and to comply with anti-money laundering and other legislation), users of bitcoin in theory operate in semi-anonymity. Since there is no central “validator,” users do not need to identify themselves when sending bitcoin to another user. When a transaction request is submitted, the protocol checks all previous transactions to confirm that the sender has the necessary bitcoin as well as the authority to send them. The system does not need to know his or her identity.

In practice, each user is identified by the address of his or her wallet. Transactions can, with some effort, be tracked this way. Also, law enforcement has developed methods to identify users if necessary.

Furthermore, most exchanges are required by law to perform identity checks on their customers before they are allowed to buy or sell bitcoin, facilitating another way that bitcoin usage can be tracked. Since the network is transparent, the progress of a particular transaction is visible to all.

This makes bitcoin not an ideal currency for criminals, terrorists or money-launderers.

4 – Immutability

Bitcoin transactions cannot be reversed, unlike electronic fiat transactions.

This is because there is no central “adjudicator” that can say “ok, return the money.” If a transaction is recorded on the network, and if more than an hour has passed, it is impossible to modify.

While this may disquiet some, it does mean that any transaction on the bitcoin network cannot be tampered with.

5 – Divisibility

The smallest unit of a bitcoin is called a satoshi. It is one hundred millionth of a bitcoin (0.00000001) – at today’s prices, about one hundredth of a cent. This could conceivably enable microtransactions that traditional electronic money cannot.
