8.0 Impact of computer applications in communicationCommunication has always played a significant role in enabling the interconnection among humans. With the acceleration of computer development in the last few centuries, people no longer have to rely on the traditional modes of communication such as postal mail and landline phones to communicate with each other. Nowadays, we are able to attain information and conduct business in a more efficient and productive manner owing to the development of computer-mediated communications such as email, video chat and all sorts of social networking sites, including Instagram, Facebook and Snapchat. 8.1 Beneficial effect on businessThe development of computer has remarkably influenced commercial business in a few ways. Communication between colleagues or business partners all over the world can now be done promptly due to advancement of computer-mediated communications. For example, the invention of video conferencing enables companies that have employers scattered around the world to carry out an efficient discussion as well as meetings. Besides that, business networking has become easier with the emergence of social media specially designed for that purpose, such as LinkedIn. Apart from that, companies can market their business online with the creation of a company website. By means of this, buyers will have 24-hour access to all sorts of information and price of desired product. Furthermore, the benefits of computer applications on the company’s finance structure can be best elucidated by the emergence of electronic commerce. The key advantage of an electronic commerce over a traditional store is that it does not have to involve physical establishment, staffing and distribution. As such, it is definitely less expensive to retain such a storefront than a traditional store. 8.2 Reaching a broader audienceWith the enhancement of people’s ability to communicate with each other, the reach of their messages broaden as well. This can be extremely crucial in politics and activism. As an illustration, photos and videos recorded covertly can rapidly be spread online through websites such as YouTube or Facebook; thus, making it more difficult for oppressive regimes to take control. For example, during the Egyptian revolution of 2011, many Egyptian activists used Facebook and Twitter as a channel for raising global awareness on this issue. They posted videos and pictures portraying the latest updates of revolution, such as a video of crowds escaping from tear gas and police in Tahrir on Youtube. Subsequently, when the government banned journalists from spreading the news around the world, protesters had utilized the presence of social media to address the world while events were unfolding.8.3 PrivacyCommunicating via computers can help people to overcome geographical gaps, but doing so may disclose a person’s privacy more than what he might want. Through a face-to-face meeting or phone conversation, there is a relative guarantee that details of the conversation will remain private. However, with email, text-messaging and social media, there is a permanent record of what people do and say. As a result, there is an underlying danger when it is possible for third parties to access these online conversations. As users always engage in these activities on public networks, they have left their personal information out in the open and can easily be taken advantage by criminals. According to a survey carried out by the Survey Shop, 78% of burglars reported that social media sites such as Facebook, Twitter and Foursquare are beneficial tools for them to target a specific property while 74% reported that Google Street View had assisted burglars in home theft. Through social media sites, burglars are able to analyse a person’s daily schedule and went the person will not be at home. As such, social media-related crime had alarmingly increased up to 780% in four years (2008-2012).
