Internet Communication Tools (Grade 12 NSC Matric Computer Application Technology): Revision Notes
Electronic Communication
Electronic communication has revolutionised how we connect with others around the world. Understanding different types of electronic communication and how to use them effectively is essential in today's digital age.
What is electronic communication?
Electronic communication refers to any data, information, words, or photos that are sent electronically to communicate with one or more people. This broad category includes various methods such as phone calls, text messages, group chats, emails, social networks, and websites.
These digital communication tools have transformed how we interact, making it easier to stay connected with people globally, though they come with both benefits and challenges. The key advantage of most electronic communication is that it operates on an asynchronous basis, meaning that a message can be sent without the message receiver being available at the time.
Advantages of electronic communication
Electronic communication offers several significant benefits that have made it indispensable in modern life:
Speedy transmission allows communication to happen within seconds through electronic media, supporting almost instant message delivery. This speed advantage means you can share urgent information or have real-time conversations regardless of distance.
Wide coverage has transformed our world into a global village where communication around the globe requires only a second. Geographic barriers no longer limit our ability to connect with others, whether for personal or professional purposes.
Low cost makes electronic communication an economical choice since it saves both time and money. For example, sending a text message costs significantly less than posting a traditional letter, and many communication platforms offer free services.
Exchange of feedback happens instantly through electronic media, making communication more interactive and effective. This immediate response capability allows for dynamic conversations and quick problem-solving.
Managing global operation becomes possible due to electronic communication advances, enabling business managers to easily control operations across the globe. Video calls, emails, and mobile communication help managers stay connected with their teams regardless of location.
The combination of speed, global reach, and cost-effectiveness has made electronic communication the preferred method for both personal and business interactions worldwide.
Disadvantages of electronic communication
Despite its many benefits, electronic communication also presents several challenges:
The volume of data creates information overload as telecommunication information increases at such a fast rate that people struggle to absorb it within relevant time limits. This constant stream of messages and notifications can become overwhelming.
The cost of development requires huge investments for infrastructural development, and frequent technology changes demand further investment. Keeping up with rapidly evolving communication technology can be expensive for both individuals and organisations.
Legal status issues arise because data or information, if tampered with, may be distorted and lose value in legal contexts. Digital communication lacks the same legal weight as traditional written correspondence in some situations.
Undelivered data problems occur when information may not reach its destination due to system errors or technology faults, causing delays in required services. Technical failures can disrupt important communications.
Dependency on technology creates challenges, especially for developing countries that cannot afford new or advanced technology. This digital divide means some regions must depend on developed countries for sharing global networks, creating inequality in communication access.
Common Challenge: Information overload is one of the most significant problems users face today. Learning to manage and prioritise electronic communications is crucial for maintaining productivity and mental well-being.
Electronic communication best practices
When communicating on the internet through any method—whether email, instant messaging, or social media—it's crucial to follow proper netiquette. Good internet etiquette not only makes the internet a more pleasant place for everyone but also protects you from potential embarrassment in the future.
What is Netiquette? Netiquette refers to the rules of etiquette that apply when communicating over computer networks, especially the internet. It encompasses everything from email manners to social media behaviour.
Guidelines when communicating on the internet
Different types of electronic communication require specific approaches to ensure effective and appropriate interaction:
Texting (messaging) guidelines
When sending text messages, keep your communications concise and clear. Keep texts short because longer messages can be misinterpreted or become confusing. Always sign a text with your name so the recipient knows who sent the message. Spell out all words and avoid using "texting lingo" or excessive shorthand that might confuse the recipient. Remember that texts can be saved and altered, so be mindful of what you write.
Email guidelines
Professional email communication requires particular attention to etiquette. Use a descriptive subject line that clearly indicates the email's purpose, making it easier for recipients to prioritise and organise their messages. Be courteous in your tone and language throughout the email. Reply promptly when possible, but allow yourself time to calm down before responding to an email that might have triggered an angry reaction. Be aware that attachments to emails may contain metadata that can disclose unwanted information to recipients.
Social media guidelines
Social media platforms require heightened awareness of privacy and security. Remember that there is no expectation of privacy on the internet—anything you post can potentially be seen by others. Change your passwords frequently to maintain account security. Log off after visiting pages to protect your account from unauthorised access. Delete your browsing history, saved passwords, and cookies regularly to protect your personal information. Do not disparage anyone via social media as this can have serious consequences. Educate yourself about a site before joining to understand its privacy policies and terms of use.
Critical Reminder: Netiquette differs from site to site and changes over time. Always research what constitutes acceptable behaviour on any website before sending your own messages.
Types of electronic communication
Modern technology offers various ways to communicate electronically, each with its own strengths and appropriate uses. Understanding these different types helps you choose the most effective method for your specific communication needs.
Email stands as one of the first and most popular forms of electronic communication. It enables users to send and receive files and messages over the internet and can be used on a wide variety of devices. Email's versatility and reliability have made it a cornerstone of both personal and professional communication.
Advantages of email
Email Benefits Overview:
Email offers numerous benefits that explain its enduring popularity:
- Free tool for most basic services
- Quick delivery - send with one click, read almost immediately
- Simple and easy to use for quick access to information
- Easy referencing - messages stored and searchable
- Accessible from anywhere with internet connection
- Paperless and environmentally beneficial
- Mass sending capability to multiple recipients
- Instant access to information and files
Email is a free tool for most basic services, making it accessible to nearly everyone with internet access. Email is quick—once you finish composing a message, sending it is as simple as clicking a button, and it can be read almost immediately by the recipient.
Email is simple and easy to use, allowing for quick access to information and contacts without complex procedures. Email allows for easy referencing since messages that have been sent and received can be stored and searched through safely and easily, creating a permanent record of communications.
Email is accessible from anywhere as long as you have an internet connection, enabling you to stay connected regardless of your location. Email is paperless and therefore beneficial for the environment, reducing the need for physical documents and traditional postal services.
Disadvantages of email
Despite its advantages, email also presents several challenges. Email could potentially cause information overload as people receive numerous messages that may be dismissed or left unread, especially when the recipient's network has not integrated some sort of email alert system into workplace computers.
Email lacks a personal touch compared to face-to-face or phone conversations, making it less suitable for sensitive or emotional communications. Email can be disruptive since going through each email can be time-consuming, and this disruption is decreased through the utilisation of an email alert system.
Email cannot be ignored for long periods, as neglecting your inbox can lead to missed important communications. Emails can cause misunderstandings because email does not include nonverbal communication, and recipients may misinterpret the sender's message, particularly if senders fail to review their messages before sending them.
Email messages can contain viruses, so it's essential to be careful when opening messages from people you don't know or downloading attachments. Email should be kept short and brief, which can be challenging if you need to send lengthy communications.
Email Response Expectations: Email requires timely responses—while some people tend to disregard messages, those requiring responses should be replied to as soon as they are received and read to maintain effective communication.
Email etiquette
When communicating by email, always follow these essential guidelines: Be polite in your language and tone. Do not write emails that are unnecessarily long, as lengthy messages can lose the reader's attention. Do not spam people with emails that they are not interested in receiving. Make sure your message is logical and clearly communicates what you intended to say.
Additional email features
Email systems offer various features that extend beyond simple messaging, making them comprehensive communication and organisation tools.
Calendar integration allows users to manage their schedules effectively. Google Calendar, for example, is a time-management and scheduling service that became available in 2006 and was released for mobile apps on Android and iOS platforms in 2009. Users can create and edit events, set reminders for events with options for type and time, add event locations, and invite other users to events.
Email Organisation Features: Modern email systems include powerful tools for staying organised:
- Contact lists for easy access to frequently used email addresses
- Tasks integration for creating to-do lists within your email account
- Archives for managing old emails without permanent deletion
Contact lists provide easy access to frequently used email addresses and contact information. You can access the contacts page by clicking the Apps icon in Gmail's interface, which reveals a panel of icons for other Google programmes and services.
Tasks integration allows Gmail users to create simple to-do lists within their email accounts. Google Tasks enables you to create lists of items, set due dates, and add notes. You can even create tasks directly from Gmail messages, helping you stay organised and manage your responsibilities effectively.
Archives provide a way to manage old emails without deleting them permanently. Rather than deleting emails and losing them forever, you can choose to archive them instead. Archived messages are removed from your inbox and tagged with the "All Mail" label, remaining in your Gmail account for easy retrieval later while keeping your active inbox organised.
Instant messaging
Instant messaging refers to short messages sent in real time over the internet. These messages can include multimedia items such as pictures, videos, and voice recordings, making them versatile communication tools for both personal and professional use.
Advantages of instant messaging
Instant messaging offers several compelling benefits for modern communication:
- Messages are free to send through most instant messaging services
- Messages are received directly after being sent, ensuring immediate delivery
- You can see if the message has been delivered through delivery confirmation features
- You can see when your message has been read through read receipts
- You can send a variety of messages including text, pictures, videos, music, and web links
- You can create group conversations to discuss specific topics with multiple people
Real-Time Communication: The immediate delivery and read receipt features make instant messaging ideal for urgent communications and coordinating activities with others.
Disadvantages of instant messaging
However, instant messaging also has notable limitations:
- Messages are not always saved automatically, risking loss of important information
- It is an informal method and might not be suited for business communications
- There is pressure to respond immediately as people can see when you read messages
- It can be distracting as one message can lead to lengthy conversations
- Low security because instant messaging services use public networks
Best practices for instant messaging
When communicating through instant messaging platforms, follow these guidelines: Do not expect an immediate reply since the person you are messaging might be busy. Keep your messages short and to the point for clarity and efficiency. Do not type using uppercase letters as this can be interpreted as shouting. Be polite in your communications. Do not use excessive slang as this might confuse others.
VoIP
VoIP (Voice over Internet Protocol) is a type of digital communication that allows users to speak with one or more people over the internet. This communication method is very similar to a phone call, with the key difference being that it uses your internet connection rather than traditional telephone networks.
Advantages of VoIP
VoIP offers several significant benefits over traditional telecommunication services. VoIP is much cheaper than using traditional telecommunication services, making it an economical choice for both personal and business communications. It can help with productivity as you can have face-to-face meetings with colleagues in different cities without the expense and time of travel.
It saves time and money as you can conduct face-to-face business meetings without having to travel to meet clients, reducing both travel costs and time investment while maintaining personal connection.
Disadvantages of VoIP
Despite its advantages, VoIP has some limitations to consider. You need an active internet connection to use VoIP services, making it dependent on reliable internet access. Audio quality depends on internet connection quality, so poor internet can result in poor call quality. Some VoIP programmes use large amounts of data, which can be costly if you have limited data allowances.
VoIP Success Tips: For the best VoIP experience, ensure you have a stable internet connection and consider the data usage implications, especially when using mobile data.
Best practices for VoIP communication
When communicating using VoIP, follow these important guidelines: Be polite and speak clearly to ensure effective communication. Indicate that you are listening to the person with whom you are speaking by providing verbal confirmation. Repeat important details to ensure understanding and avoid miscommunication. Do not be afraid to ask questions if something is not clear during the conversation.
Video conferencing
Video conferencing takes VoIP communication one step further by adding visual elements to internet-based calls. Everyone can see you all the time during video conferences—this is not an audio conference, and just because you are not speaking does not mean others cannot see you.
Professional Video Conference Standards:
Video conferencing requires particular attention to professional presentation:
- Be punctual and courteous - treat it as an on-site meeting
- Avoid multitasking - others can see you, so stay focused
- Maintain appropriate behaviour throughout the call
- Ensure good lighting from the front
- Dress appropriately in business casual attire
- Choose an appropriate location at your desk or professional space
Best practices for video conferencing
Be punctual and courteous by arriving on time and treating the video conference as you would an on-site meeting. Introduce yourself and take note of other attendees' names so you can address them by name during the conversation. Turn off ringers for your other phones and treat the video conference with the same respect as an in-person meeting.
Avoid multitasking during video conferences. Others can see you, so look at your screen, pay attention to other participants, and when speaking, make sure to look at your camera to maintain eye contact with other participants.
Maintain appropriate behaviour throughout the call. If it is improper for a face-to-face meeting, then it is equally inappropriate for video conferencing. Avoid clicking your pen, tapping on your desk, or anything else that might be annoying or distracting.
Ensure good lighting by adjusting your lighting or using a portable light source to make sure you have good illumination from the front. You can experiment with positioning until you find a good balance, such as pointing a strong desk lamp at the wall you're facing.
Do not eat or drink inappropriately during video conferences. While you may enjoy a glass of water or coffee, drinking wine or beer is not acceptable. Do not smoke during meetings either.
Dress appropriately for video conferences. Even though we might enjoy sitting in casual clothes in our virtual offices, it is not appropriate when you are called into a virtual meeting. Business casual attire should be considered for all video conferences.
Technical Preparation: Always ensure you have the current client version loaded before scheduled calls and test your audio and video beforehand. Close unused applications since video conferencing can be CPU and memory intensive.
Choose an appropriate location for your video conference. Conduct video calls from your desk or another appropriate location rather than lying on the couch, as this does not present a professional appearance.
Manage your environment by ensuring your workspace looks professional. If you have a cluttered work space, make sure it's not showing up on camera. Avoid high-traffic areas where other people will be walking through the view of the camera regularly.
Minimise distracting elements by avoiding stripes or heavy patterns in your clothing. If you have vertical mini-blinds, avoid having them in the background, and minimise hand gestures and body movements to maintain a professional appearance.
Use the chat feature appropriately by considering posting your comments or questions in the chat window rather than interrupting the speaker. Monitor your appearance by using picture-in-picture view as your reference.
Safety Warning: Never video conference while driving as this is extremely dangerous and inappropriate.
