Mediums of Digital Communication
We are living in the Information Age, and the digital technologies have revolutionized communication in the modern world. The Internet and cell phones are two of the most prominent examples of the influence of the Information Age, but there are many other types of digital communication technologies used nowadays. There are many different ways of communicating digitally. Most of them are used in everyday situations. Some of the most common mediums of digital communication are:
Electronic mail (or e-mail)
It is a method of creating, sending, storing and receiving messages over an electronic communication system. It uses a protocol (a rule) for sending messages called Simple Mail Transfer Protocol (SMTP for short). One can send e-mail over an internet connection or over an intranet (a collection of computers within a specific area like an office building). E-mail users can communicate to each other by sending and receiving messages. Sometimes you want to store messages to read later and your email software will allow you to do this.
Instant messaging (IM) is like e-mail but it is done in real time (get a response very quickly). The instant messaging software installed on the computer and in the software a contact list of people is set-up with whom one wants to connect. Most IM software lets you know who is on-line and available to chat. You can send text, pictures and even video using IM and whoever you are communicating with can respond as soon as they see the text appear in their IM software.
Mobile phones are used by lots of people today to talk, send text messages, take and send pictures, listen to music, or surf the internet. In fact you can do so much with a mobile phone it can be a complete communication tool. The Short Message Service (SMS) allows text messages to be sent and received via your subscriber service. If the phone you are sending the text message to is out of range or turned off, the service provider will store the text message until it can be delivered.
PDAs (Personal Digital Assistants) are hand-held computer devices that can perform a number of different things, like receiving e-mails, sending messages, writing text (in a word processor). Newer PDAs are also telephone devices, receiving both audio and video. A PDA connects either through a local telephone network, or a local intranet or an internet connection.
Forums or Newsgroups
A forum or newsgroup is an online discussion group where people can subscribe (join) a group and post messages to that group. They can take part in discussions with other people in the group and reply to messages posted by other members of the group. The group can be closed (private) which is often used for communication between project groups working on a project together, like a survey or sharing project documents. An open (public) group is often used by people sharing a common interest. When you join a group you will need to register your details. This creates an account for you so you can post e-mail messages to the group.
A thread is just a group of related messages on a particular topic, for example pruning roses, or the latest film, everyone in the group has seen.
Emoticons are little graphical pictures that represent how people are feeling, like a smiley face for happy, or a face to say you agree with something.
A blog (‘web log’) is a form of online journal that allows text, images and video clips (and links to websites) to be displayed as a webpage but also allows comments to be posted by readers of the blog. Some blogs ask you to register with the site first before allowing you to post anything. There can be moderation of posts as with forums but that is determined by the owner/administrator. Blogs often contain information about a particular topic like food, politics or local news. A blog contains text, images and links to other blogs, forums or other web pages related to the blog topic.
Skype is not new to communication. It has been around since 2005, but has become very popular. Skype users receive calls on their computers dialled by regular phone subscribers to regular phone numbers. Skype permits users to subscribe to numbers in many countries including the UK and USA. Callers pay only local rates to call a number. Skype supports voicemail, chat, video calling, SMS messaging to mobile phones and skype casting. Multiple users can access Skype. A user will need a headset and a microphone or a Skype handset, which looks very like a mobile phone to talk to other Skype users. Video conferencing
Video conferencing provides two-way video transmission between different sites. It could be between two buildings, or even across different countries. Every video conferencing facility allows for call setup, call coordination and display of participants. It is normally used with a video conferencing screen so you can see the people in each of the video conferencing rooms. Video conferencing makes use of specialist equipment like a computer, video camera and a network like an intranet or internet connection to connect the two sites together. Video conferencing can save people time, and the expense of travelling between sites for meetings.
