Digital Marketing World
Another Planet
Digital marketing is two different words digital means using social media platform which works digitally (0 or 1) and marketing means to publish own products via social media. When these two words joined together suddenly the world is changed. You may say we are into the MARS OF digital marketing. If we go a few years back, traditional marketing was important for every small or big company they use flyers, billboards and freelancers to go for door-to-door marketing. Big companies go for television advertisements. They hire highly competent MBA to make their plans and strategies. Time, money and a big team required, knocking on doors, and using traditional advertising are over. The average person spends at least 5 hours per day online. This simple fact is all the reason why you need a digital marketing strategy. Who is the father of digital marketing? The “father of digital marketing,” Philip Kotler, is often referred to as such. He is an American professor who is credited with founding marketing as an academic discipline and has produced over 60 marketing books. Digital Marketing was founded to help organizations significantly increase and protect their online marketing presence by focusing on three main areas.

Clock Ticks The Technology Clicks
Technology:
“It is mind science, based on scientific knowledge to the practical aims of human life observation”.
Meaning
Technology: The two Greek words, transliterated ‘techne’ and ‘logos’ Techne means art, skill, craft, or the way, manner, or means by which a thing is gained. Logos means word, the utterance by which inward thought is expressed, a saying, or an expression. So, technology means words or discourse about the way things are gained.
When waking up in the morning day and time change, but as the clock ticks the technology clicks. Behind every invention, there is one person because that person thinks differently. The Information Age (also known as the Computer Age, Digital Age, Silicon Age, or New Media Age) is a historical period that began in the mid-20th century, characterized by a rapid epochal shift from a traditional industry established by the Industrial Revolution to an economy primarily based upon information technology This the era of electronics and communication. we use different tools for example GOOGLE! Global Organization of Oriented Group Language of Earth The technology which makes human works. Bill Gates, Larry Elison, Steve Jobs, Elon mask, and Larry Page are the father of new technology. Technology is divided into 4 main ages. There are pre-mechanical, mechanical, electromechanical, and electronic.
Father Of Old And New Technology:
Albert Einstein called Galileo the “father of modern science.” Galileo Galilei was born on February 15, 1564, in Pisa, Italy but lived in Florence, Italy for most of his childhood. The Father of old technology is Thomas Alvis Edison father of invention. The simple version of the story of Thomas Alva Edison the one most school children learn is that he invented the phonograph the incandescent light bulb and the motion picture camera. Charles Babbage was an English polymath. A mathematician, philosopher, inventor, and mechanical engineer, Babbage originated the concept of a digital programmable computer. Babbage is considered by some to be the “father of the computer”.
The computer age began when ENIAC (Electronic Numerical Integrator and Calculator) was completed in 1945. The first multipurpose computer, ENIAC set speed records with an amazing 5,000 additions per second. Computers have come a long way since—a laptop today can do 500,000,000 additions per second. Bill Moggridge will long be remembered as a trailblazing designer and the father of the modern laptop. The Osborne 1 was accepted as the first truly mobile computer (laptop, notebook) by most historians. Adam Osborne founded Osborne Computer and formed Osborne 1 in 1981. Wi-Fi, often referred to as WiFi, wifi, wi-fi, or wi-fi, is often thought to be short for Wireless Fidelity but there is no such thing. The term was created by a marketing firm because the wireless industry was looking for a user-friendly name to refer to some not-so-user-friendly technology known as IEEE 802.11. Brain, the first PC virus, began infecting 5.2″ floppy disks in 1986. As Securelist reports, it was the work of two brothers, Basit and Amjad Farooq Alvi, who ran a computer store in Pakistan. The first handheld cellular mobile phone was demonstrated by John F. Mitchell and Martin Cooper of Motorola in 1973, using a handset weighing 2 kilograms (4.4 lb). The first commercial automated cellular network (1G) analog was launched in Japan by Nippon Telegraph and Telephone in 1979. When was the 1st cell phone invented? September 2008 It was unveiled in November 2007, with the first commercial Android device, the HTC Dream, being launched in September 2008.
Pros And Cons:
Take an example of the internet we can watch good things and easily watch porn sites. which is the most searched site in the world. Children waste their time by playing games. It has positive and negative effects on the world and it impacts daily lives Pros cons Everything has pros and cons. Eating healthily keeps us fit and fine. Eating unhealthy makes us lazy. Using a computer for 45 minutes per hour is healthy but using a computer or any other device makes us tired. Smart use of technology gives the solution.
Technology is to make life easy use it but don’t misuse it. Smart use of technology creates a great mind like Bill Gates. What to do and what is the use of a computer. Now everyone depends on technology. If we go 30 years people used to be fit and fine because they spend their time in the gym or going to meet with friends and families. now technology makes it easier. 3 to four hours of sitting in front of computers and using a cellphone create another disease which is depression. Our mind needs relaxation more than the body. Made nearly two million years ago, stone tools such as this are the first known technological invention. Technology affects the way individuals communicate, learn, and think. It helps society and determines how people interact with each other daily. Technology plays an important role in society today. Mind Science is defined as the observation, identification, description, experimental investigation, and theoretical explanation of natural phenomena. Everyone is gifted by the brain to covert that brain into thinking mind is called mind science. like a machine. The communication and information industry is growing faster. This proves that the human brain is faster than the computer.
Formula of Education = Observation + Skills

Education is never ending and sensitive topic. Everyone wants to be educated. Most of us think that education is a degree to get a job. Think that we are going to university to learn new things every subject will be easier for us. Well, I have to justify the formula as well but before that, we have to understand, why education is a powerful tool.
“Education is the most powerful tool that can change the world (Nelson Mandela).”
