Marketing

  

Marketing refers to a process which helps in identifying and understanding the customers and giving them their needs. It is created by companies to have a strong relationship between the customers and gain profits from the customers. It's main purpose is to identify, satisfy and keep the customer. With marketing process a business can run smoothly and companies will make profit. If the marketing process is effective then it results to examining every aspects of  business and way it affects the customer's and experience. Marketing in today's business world has an massive effect. A business runs in failure without the marketing. It has become a key to success for business.  

Uses Of Computer

Computer has brought a drastic change in human life. It have become indispensable in today's world. Here are some uses of computer.

•  Word Processing-Word Processing software automatically corrects spelling and grammar mistakes. If the content of a document repeats, you don't have to type it each time. You can use the copy and paste features. you can print documents and make several copies.  
• Internet- It is a network of almost all the computers in the world. You can browse through much more information than you could do in a library. That is because computers can store enormous amount of information. Though E-Mail you can communicate with a person sitting thousands of miles away in a few seconds. Chat software enables one to chat with another on a real-time basis. Video conferencing tolls are becoming readily available to common man.
• Medicine- You can diagnose disease. You can learn the cures. Software is used in magnetic resonance imaging to examine the internal organs of the human body.
• Banks- All financial transactions are done by computer software. They provide security, speed and convenience.
• Telecommunication- Software is widely used here. Also all mobile phones have software embedded in them.
• Business- Shops and supermarkets use software, which calculate the bills. Taxes can be calculated and paid online. There are fully automated factories running on software.
• Planning and Scheduling - Software can be used to store contact information, generating plans, scheduling appointments and deadlines.

Disadvantages Of Computer

 Every great invention has a negative impact, so we should be careful about it. Here are some  disadvantages of computer:

• Computers can make the mind lazy. You get used to not reading a book, or researching something at library.
• Spending too much time playing  online games or chatting over the computer instead of reading books, doing homework.
• It takes one away from socializing with others in person.
• Being on a computer also harms our eyes and create other physical problems.
• Being on a computer too much can also lead to anti social behavior and depression.

Importance Of Computer

In today's world computer has a vital role. Almost everything is done by computer nowadays. So, we need to learn about computer. With the knowledge of computer we can also built our career. With the help of computer people are earning millions and billions of dollars. Bill Gates, the worlds richest man has become rich because of computer. Computer helps children to learn faster rather than the text books.

History of computer

The first use of word "computer" was recorded in 1613, referring to a person who carried out calculations, or computations, and the word continued with the same meaning until the middle 20th century. From the end of the 19th century the word began to take on its more familiar meaning a machine that carries out computations.

                    Charles Babbage developed the first analytical engine in 1812. This machine had the concept of modern computer namely memory, arithmetic unit and capacity to handle stored programme. But this machine could not be put into practical applications due to technologies limitations that time.
                       The history of modern computer begins with two separate technologies, automated calculation and programmability, but no single device can be identified as the earliest computer, partly because of the inconsistent application of them. A few devices are worth successful and survived for centuries until the advent of the electronic calculator, like the Sumerian abacus, design around 2500 BC of which a descendant won a speed competition against a modern desk calculating machine in japan in 1946, the slide rules, invented in the 1620s, which were carried on five Apollo space missions, including to the moon and arguably the astrolabe and the Antikythera mechanismn an ancient astronomical computer built by the Greeks around 80 BC. The Greek mathematician Hero of Alexandria (c. 10-70 AD) built a mechanical theater which performed a play lasting 10 minutes and was operated by a complex system of ropes and drums that might be considered to be a means of deciding which parts of the mechanism performed which actions and when. This is the essence of programmability.

Third Generation Computer(1960s)

IBM System/360

The invention of the integrated circuits (ICs), also known as microchips, paved the way for computers as we know them today. Making circuits out of single pieces of silicon, which is a semiconductor, allowed them to be much smaller and more practical to produce. This also started the ongoing process of integrating an even large number of transistor onto a single microchip. During the sixties microchips started making their way into computers, but the process was gradual, and second generation of computers still held on.
                   First appeared minicomputers, first of which were still based on non-microchip transistor, and later versions of which were hybrids, being based on both transistor and microchips, such as IBM's System/360. They were much smaller and cheaper than first and second generation of computers, also known as mainframes. Minicomputers can be seen as a bridge between mainframes and microcomputers, which came later as the proliferation of microchips in computers grew.
