Major Developments And Future Trends Computer Science Essay

Published:

In recent years personal computing has advanced considerably. Twenty years ago, computers could be anything up to a size of a room. They were hard to operate and required multiple personal to perform basic tasks. One of the major developments were by Bill Gates the founder of Microsoft Corporation. Bill Gates developed a operating system which collects software that manages computer hardware resources and provides common services for computer programs. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware later became known as Windows. Meaning that you no longer had to use a manual to use a personal computer, it came simple and efficient. Later other operating system competed with windows, such as Liniux and Macintosh.

Creating a operating system simplified the use, the stroke of genius came with the creation of world wide web, which allowed to share files simultaneously and freely through the world. Later social media sites like "Facebook" became the attraction of the internet, hundreds of people use Facebook to communicate with their friends, share photos and discuss day to day topics. Also programs such as Skype allowed video calls. But to make sure all of those functions would be carried out, the developments of major components were required. AMD develops micro-processors, Cursair Air develops Random Accessed Memory (RAM) and many more all those inventions and developments lead to the world which we live in today. By reducing the size of technology it became cheaper to produce which lead to bigger usage. Many business in today world would not be able to operate properly and as efficient without the development of technology. With a smaller microchips, development of smartphones were possible, notebooks and laptops.

History of Technology

Microsoft.

Microsoft was established by Bill Gates and Paul Allen on April 4, 1975. Microsoft develops, manufactures, licenses and supports a wide range of products and services related to computing. One of the biggest Microsoft successes were its operating system "Windows".

Windows allowed simple use of computer. The first version of Windows was released in 1983, Windows 1.0 and it ran on a floppy disk of 256kilobytes. Windows quickly dominated the market and became the most used operating software in the world. With the success of Windows 1.0, bill gates continued to develop the operating system. It was named Windows because it was referred to the windows which popped up with a mouse click. Before the release of windows, users had to use Binary code in order to operate the computer, which was complex and consisted only of numbers (010101010)

By creating Operating system a whole new market was available. Because of the growth of the people using the computer, a simple and effective way had to be developed to transfer data with the world. This lead to the invention of World Wide Web.

World Wide Web

World Wide Web is commonly known as the web. It invented by Sir Timothy John who is a British computer scientist. The World Wide Web is a system of interlinked documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia. World Wide Web was a huge success and it lead to free sharing of files. People began "uploading" photos with a click of the button as software developed. Social Media sites such as Facebook became into existence, and today more than five hundred million people use Facebook.

Facebook

Facebook was developed by Mark Zuckerburg. It was originally limited only for Harvard university but quickly expanded all though the Boston and the world. Facebook allows a simple way of communicating with friends, college students and employees. Facebook allows to share photos and other media.

Problems regarding security and ethics.

Introduction

Privacy, security and ethics are the most vital issues in today's world and the most important rights.

Security

Every single person using the internet wants to feel secure from online threats, which can relate to people who try to harm your computer for personal data, they are referred as "hackers". Usually people attempt to protect themselves from viruses which try to gain your private information regarding bank details, addresses and other vital peace of information. One way people protect them by purchasing an anti-virus software.

Antivirus

Is software used to prevent, detect and remove malware which may harm your computer. No matter how useful antivirus software can be, it can sometimes have drawbacks. Antivirus software can impair a computer's performance

Antivirus works by signature-based detection involves searching for known patterns of data within executable code. However, it is possible for a computer to be infected with new malware for which no signature is yet known. Some antivirus software can also predict what a file will do by running it in sandbox aka controlled environment and analysing what it does to see if it performs any malicious actions.

People purchase antivirus to feel saver surfing the World Wide Web or downloading and exchanging files.

Recently, a vigilante group known as Anonymous attacked Samsung Corporation and disabled the online network of Play station 3. Leaving thousands of user's information in jeopardy. Anonymous was able to access all information, from street address to bank details stored in Samsung servers. Nevertheless, the information was not used for personal reasons, because anonymous attacked Samsung for its policy on customers which many felt that it was breach of security and privacy. Samsung suffered damage amounting to millions.

Privacy

The ability for individuals to interact online without sacrificing their personal privacy is a vital part of the Internet's value, and is intimately related to its trustworthiness.

Every single person wants to have certain degree of privacy when they publish information online or in a blog. Some people wish to be unknown on publication because of his/her status in the society. Privacy protects every single user with its basic right: freedom of speech. There is multiple situations involving multi-national corporations or even governments attempting to access private information by group of individuals.

It was registering every single email sent and analysed for conspiracy. In response Google has shut down its servers in china and moved to Hong Kong where Japan was in control.

Also Facebook was accused of selling information to third parties regarding persons "likes" and preferences.

Ethics

Ethics is also known as moral philosophy, is a branch of philosophy that involves systematizing, defending, and recommending concepts of right and wrong conduct. Ethics is very important in today's society. Parents should educate children using internet regarding appropriate websites, do's and don'ts. There a number of reports across the world of children being bullied on social media sites and chat rooms or even forums. Ethically educating children in schools would decrease the chance of bullying

In recent news, elderly man as accused of violent crime. Hundreds of twitter users "tweeted" about the person and the crime committed.
