Term Explanation
security issues for communications systems In various communications systems, there are multiple security issues.
Some of these issues may include:
- Interception of data and information.
- Outside access to a users computer, via interference.
- Sharing of virus' throughout connected systems.
globalisation issues for communications systems Consider the impact of the Internet.
Check this visualisation (SuperPower: Visualising the internet) of the Internet in terms of numbers using it and where (from the BBC)
In 2008 the Internet is accessed by almost 22% of the world population, however this number is highly skewed towards particular countries and particular socio-economic groups. Countries like those in Western Europe, North America and Oceania have a much bigger percentage of their populations who are able to go online. In North America 73.6% of the total population have access to the Internet, and this is by far the highest amount worldwide. The next biggest numbers are fairly far off with 59.5% for Oceania and 48.1% for Europe. With the Internet meaning so much in terms of networking and connectivity between industries, the lack of its relative availability in certain regions of the Earth could lead to problems with future global economic equality. The impact of internet on globalization has both positive and negative aspects. The positive impact of the internet technology on globalization include the modernization and improvement in the business sector on a world wide basis. Businesses improve their global competitiveness and productivity with more efficient electronic transaction processing and instant access to information.
changing nature of work issues for communications systems
interpersonal relationships issues for communications systems
  • Online Dating sites. Often people are compatible online but react differently when face-to-face.
  • Online forums give individuals equal opportunities to submit ideas and comments. In face-to-face situation, their comments can be rejected by the experts.
  • Text messages and e-mails can be misinterpreted. There is no body language, tone of voice or facial expression in this form of communication.
  • All people are equal in electronic communication. On the Internet we are not aware of any disablitlies
e-crime issues for communications systems E-crime or computer crime is a form of crime where computers are used as a medium to commit crime. Some of the issues that are involved in e-crime are:
  • Copyright infringement
  • Cyber Abuse
  • Fraud and identity theft
  • Phishing scams
  • Information malware
A common example of fraud and identity theft is when malware is installed onto the users computer without the users knowledge and personal informationof the user is transferred to another user.
virtual communities issues for communications systems
current and emerging trends in communications
  • blogs
Blogs is short for web log, which is basically a journal that is made public by placing it on the internet. The composer of the blogs can regularly update their blog to express their opinion of personal view on issues, it act simply as a diary which describes their day to day lives. They mostly placed in date order with the latest post on top to provide a chronological order which is easily followed by an audience.
  • wikis
A wiki is a website where users are able to freely add new content and edit existing content. The term wiki comes for a Hawaiian phrase "wiki wiki" which means "super fast", the implication being that the amount of content grows rapidly due to the large number of authors. Wikipedia is the largest and most famous wiki in the world, but due to the fact its open to the public and edited by the public, the information shouldn't be taken as face value.
  • RSS feeds
RSS (Rich Site Summary) is a format for delivering regularly changing web content. Many news-related sites, weblogs and other online publishers syndicate their content as an RSS Feed to whoever wants it. RSS solves a problem for people who regularly use the web. It allows you to easily stay informed by retrieving the latest content from the sites you are interested in. You save time by not needing to visit each site individually.
  • podcasts
A “podcast” is a buzzword to describe a very simple concept: an audio or video file available on the Internet for you to listen to and/or watch. A podcast can also refer to a series of these audio or video files (similar to how a TV or radio “show” can be a series of shows or just one show). When using the word “podcast”, most people refer to the entire series and not just one audio or video file.
  • YouTube & online broadcasting

  • online radio, TV and video on demand
Video on demand (VOD) is a method of showcasing streaming videos. Streaming videos are viewed as they are being delivered, similarly to radio and television. With VOD, the video is derived from a main server or network and viewed on a television or computer screen.
  • 3G technologies for mobile communications
Third generation mobile phone technology or 3G is an extension of 2G. 3G operates on a different radio frequency to 2G, allowing better clarity and access to global roaming between 3G networks. 3G offers a higher data rate transfer than 2G, has a greater capacity than 2G and is also capable of operating on 2G networks. 2G was designed for slow transmission, with simple voice data being its main function. 3G is built for speed and versatility.
  • social networking
"Social Networking in Plain English" introduces the basic ideas behind Social Networking. The video focuses on the role of social networking in solving real-world problems. The video includes:
  • The role of people networks in business and personal life
  • The hidden nature of real-world people networks
  • How social networking sites reveal hidden connections
  • The basic features of social networking websites
  • twitter
"Twitter in Plain English" introduces the popular micro-blogging service Twitter. The video focuses on Twitter's ability to connect people in new ways, using short messages. The video includes:
  • Why answers to the question "what are you doing" are interesting.
  • The mechanics of Twitter - signing up, sharing and reading messages
  • How a skeptical person fell in love with Twitter


  • web 2.0
Web 2.0 - Wikipedia, the free encyclopedia
the use of communication systems to share knowledge, not just data Thanks to the Internet, information sharing is no longer limited to snail mail or phone calls. The Internet has provided instant information sharing that can be performed all over the world on any day or at any time.

Email

The Internet allows you to send email to friends and family. They no longer have to wait for snail mail. They will receive your message in a matter of seconds.

FTP

FTP, or File Transfer Protocol, allows you to transfer your files via the Internet. File-sharing programs found on instant messengers use this technology. This technology is also found inside all Windows operating systems.

Facebook and MySpace

Thanks to the creators of Facebook, you can upload digital photos to share with your friends. On MySpace, you can upload videos that can be seen by your friends or anyone on the site.

Company Information Systems


With company information system designs, such as a WAN network, you can share information within your company at different locations. All you need to do is save the information to the network that can be transferred over the Internet. It can be received by employees who have clearance to access that area of the company's network.

Management Information Systems

MIS, or Management Information Systems, can be installed into a company website. These systems can update records stored in the embedded database, receive payments and ship sales to customers.
issues related to messaging systems
  • ideas delivered by this means appear less forceful and caring than ideas delivered personally
  • danger of being misinterpreted
  • power relationships
  • privacy and confidentiality
  • electronic junk mail
  • information overload
implications of Internet trading - eTrade
The increase of eTrading has had some important implications:
  • Reduced cost of transactions - By automating as much of the process as possible (often referred to as "straight-through processing" or STP), costs are brought down. The goal is to reduce the incremental cost of trades as close to zero as possible, so that increased trading volumes don't lead to significantly increased costs. This has translated to lower costs for investors.
  • Greater liquidity - electronic systems make it easier to allow different companies to trade with one another, no matter where they are located. This leads to greater liquidity (i.e. there are more buyers and sellers) which increases the efficiency of the markets.
  • Greater competition - While etrading hasn't necessarily lowered the cost of entry to the financial services industry, it has removed barriers within the industry and had a globalisation-style competition effect.
  • Increased transparency - Etrading has meant that the markets are less opaque. It's easier to find out the price of securities when that information is flowing around the world electronically.
  • Tighter spreads - The "spread" on an instrument is the difference

the difficulties of censoring content on the Internet There's no denying that the Internet contains a lot of material that most parents wouldn't want their children to see. Whether it's pornography, hate speech, chat rooms or gambling sites, many parents worry that their children will be exposed to negative or even dangerous content. While some opponents of censorship may feel that parental supervision is the best way to keep kids safe online, many parents point out that it's difficult -- if not impossible -- to oversee a child's access to the Internet all the time. Many parents turn to software and hardware solutions to this problem. They can purchase Web filtering programs like Net Nanny or CYBERsitter to block access to undesirable Websites. These programs usually have a series of options parents can select to limit the sites their children can access. These options tell the program which filters to enable. For example, CYBERsitter has 35 filter categories, including pornography and social networking sites. Most Web filters use two main techniques to block content: Blacklists and keyword blocking. A blacklist is a list of Web sites that the Web filter's creators have designated as undesirable. Blacklists change over time, and most companies offer updated lists for free. Any attempt to visit a site on a blacklist fails. With keyword blocking, the software scans a Web page as the user tries to visit it. The program analyzes the page to see if it contains certain keywords. If the program determines the Web page isn't appropriate, it blocks access to the page.

Another option for parents is to install a firewall. A computer firewall provides protection from dangerous or undesirable content. Firewalls can be software or hardware. They act as a barrier between the Internet and your computer network. They only let safe content through and keep everything else out. Firewalls require a little more involvement from the network administrator (in this case, a parent) than Web filtering software. Tech-savvy parents might not have a problem installing and maintaining a firewall. Others prefer to use Web filters, which do most of the work for them.
issues arising from Internet banking
  • security of banking details
Internet banking uses the http protocol together with SSL(Secure Sockets Layer) or TLS(Transport Layer Security) protocols. SSL and TSL operate within the OSI transport layer just above TCP. Both these Communication Control and Addressing Level protocols use public key encryption to ensure the secure delivery of data in both directions.
  • changing nature of work
Electronic communication systems have changed the way many people work and where they complete their work. For many the use of electronic communication systems is required. Communication systems have allowed access to their work and from home and virtually any other location with access to the internet.
  • branch closure and job loss
Because of electronic banking the need and demand for branches and staff in these branches to access your money has plummeted. This means that the jobs that were once available in these branches, no longer exist. It also has forced a lot of branches to close because the banks no longer needed them.
the removal of physical boundaries by enabling
  • work from home
Its difficult to determine the real nature and location of online businesses. A single person can setup a website that appears to represent a large corporation. Such businesses can be setup quickly and they can be dissolved just as quickly. The legal safeguards available in Australia are not present in many other countries. In general Australian law does not apply to international transactions.
  • virtual organisations, ie organisations structured around the communication system
Virtual organisations and communities are created as needs arise. Some are based on common areas of interest, to collaborate on a particular project or to form relationships. Participants in such organisations are largely honest and genuine, however in many cases ethical behaviour cannot practically be enforced.
  • removal of national and international barriers to trade
Most people speak just one language. As a consequence we seldom communicate with those who speak a different language. This greatly restricts our ability to understand and empathise with other cultures despite the removal of physical boundaries.
