Programming Languages

Programming languages are set of instruction that follow set of rule called algorithm and used to develop program(Software).

there are several popular programming languages---

a) C:- C is a structured (procedural) programming language developed by Dennis Ritchie at AT&T Bell Lab in 1972.C is basic of programming language.

b) C++:-After development of c programming language programmer face many difficulties so in 1979 Sir Bjarne Stroustrup develop C++ programming language. It is object oriented programming language that follow the concept of OOPs.

c)Java:-Java is a plateform independent Object Oriented programming language.It is developed by James Gosling , Mike Sheridan  and Patric Naughton in 1991. Initialy its name was OAK but after few years in 1995 its was Java.

d) C#:- C Sharp(#) is a Object Oriented Programming language that developed by Microsoft

.It is widely used to develop Mobile Applications, Windows Application, Web Application , Console Application and Enterprise Applications.

e)Python:-Python is an advanced programming language that is interpreted, object-oriented and built on flexible and robust semantics.Its widely used in Machine Learning and Artificial Intelligence.

f)Ruby :-Ruby is an open-sourced, object-oriented scripting language that can be used independently or as part of the Ruby on Rails web framework.


g)PHP:- php is open-source scripting language designed for creating dynamic web pages that effectively work with database. It is also used as a general purpose programming language.

Let's Know About Generation of Computer

First Generation(1940-1956)

a)First Generation Computer Uses Vacuum Tube for circuitry and Magnetic  Drums for storage medium(Memory).

b)In this generation computer is very large,expensive and take more time for execution.

c)Computer Uses Machine language (binary language) ,lowest level programming language understand by computer.

d)The UNIVAC and ENIAC computers are example of first-generation computing devices.


Second Generation(1956-1963)

a)Second Generation Computer Uses Transistor.The Transistor was invented at Bell Labs in 1947.

b)In this Generation Computers became very efficient , faster and smaller than First Generation computers.

c)Programmer uses assembly language for programming purposes and assembler for convert assembly language to machine language.

d)High-Level Programming language also has been developed like FORTRON and COBOL

Third Generation(1964-1971) 

a)Computers Uses Integrated Circuit(IC). IC  was built using silicon chip called semiconductor.

b)Compter is very faster,efficient and smaller than second generation Computer.

Fourth Generation(1971-Present)

a)Computer uses microprocessors thousands of Integrated Circuit built on to a single silicon chip.

b)Computers are very cheap,efficient,fast and small.

Fifth Generation( Present and Beyond)

a)Fifth Generations computers uses Artificial Intelligence which are very smart in working.

b)Voice Recognition,Face Recognition and parallel processing are used.

c)Quantum Computing and nanotechnology will be used.

Amazon buys startup Ring in $1 billion deal to run buyers home security

 

Amazon.com Inc has agreed to buy video doorbell maker, the companies said on Tuesday, in what analysts see as a growing bet on delivering packages inside of shoppers' homes and on home security.

The deal valued Ring at more than $1 billion, a source familiar with the matter told Reuters. Amazon declined to discuss the terms.

Ring is set to be one of Amazon's most expensive takeovers, after its $13.7 billion deal last year for Whole Foods Market.

The world's largest online retailer believes that selling internet-connected gadgets from Kindle e-readers to its new Cloud Cam will spark more shopping on Amazon.com. Ring offers the company a popular consumer electronics brand that it might not have replicated internally.

More importantly, Ring's security devices could work well with Amazon Key, a smart lock and camera system that lets delivery personnel put packages inside a home to avoid theft or, in the case of fresh food, spoiling.

"As Amazon moves more aggressively into the grocery delivery space... we believe smart security devices will be an important factor in driving user adoption," Baird Equity Research analyst Colin Sebastian said in a note.

Amazon's Alexa Fund, which offers venture capital to companies working on voice technology, invested in the Santa Monica, California-based Ring.

Currently, Ring devices can integrate with Amazon's voice-controlled assistant Alexa. Users of Amazon's Echo Show device can say, "Alexa, show my front door" to receive a live feed of activity around their home via Ring cameras.
