Chapter: 08. Online Surfing And Cyber Security

⁠

VoIP offers several advantages, including lower communication and infrastructure costs, and the flexibility to be used on various devices like PCs, laptops, and mobiles. Calls between VoIP users are typically free. However, VoIP also has disadvantages such as potential loss of data, reduced reliability compared to traditional phone lines, and delays due to heavy Internet traffic. Furthermore, it may not offer connectivity in rural areas and villages.

⁠

A social networking service is an online platform where individuals with common interests or activities can connect, share views, ideas, suggestions, and multimedia content like audio, video, and images. While they serve as vast sources of information and marketing hubs, a general drawback for students is that they are often considered a significant source of distraction from education, impacting their focus and study time.

⁠

E-mail, or electronic mail, allows users to send messages and files from one computer to another over the Internet. It is a very fast and efficient means of communication, typically delivering messages within seconds regardless of geographical distance. A key benefit is the ability to send the same message to many people simultaneously, making it highly convenient for personal and professional communication.

⁠

Cloud storage is a service that allows users to store and manage their data on remote servers, rather than on their local computers or physical devices. Its popularity has surged because it eliminates the need to buy and carry physical storage devices. Users can access their files and even expensive software from anywhere in the world by simply logging into their account, offering immense flexibility and cost-efficiency.

⁠

Cyber threats are criminal activities that use computers to damage or steal data, or to disrupt a person’s digital life, often for personal profit. Hacking involves accessing someone’s computer or account without permission, which can sometimes be done ethically by organizations to find security flaws. Cracking, however, is specifically the illegal process of breaking security systems to gain unauthorized access, usually with the intent to steal personal information, change financial data, or engage in malicious activities.

⁠

Video conferencing is highly useful as it allows people at different locations to communicate face-to-face with both audio and video simultaneously. In business, company representatives from various places can hold meetings, saving travel time and costs. For education, it promotes e-learning by bringing the knowledge of teachers and lecturers to remote areas, bridging geographical gaps in access to quality education.

⁠

A newsgroup is an online discussion group dedicated to a specific topic, where all participants share a common interest. Members contribute to the discussion by posting their comments or views on the topic, as well as responding to others’ comments. A News Admin typically manages the newsgroup, overseeing the discussion by checking comments, deciding when to conclude discussions, and approving comments or articles before they are publicly posted.

⁠

Cyber security is the process of protecting computer resources, including networks, devices, programs, and data, from unauthorized access, damage, or attack. Cyber crimes are increasing globally due to several factors, such as the ever-growing use of the Internet, a prevalent lack of awareness among users about online risks, complex multi-pronged attacks, existing loopholes in software, and a large number of untrained Internet users.

⁠

E-banking offers significant benefits to both bankers and customers. For bankers, it leads to reduced transaction and infrastructure costs, fewer human errors, and decreased paperwork, ultimately enhancing customer satisfaction and loyalty. Customers, on the other hand, enjoy the convenience of banking from anywhere without geographical restrictions, often at lower costs, and with reduced chances of fraud compared to traditional banking methods.

⁠

Netiquettes, or Network Etiquettes, are crucial in online communication because face-to-face interaction is often absent, increasing the risk of misunderstandings or misinterpreting remarks. Following these rules helps ensure clear, respectful, and effective communication. Two examples include avoiding typing in all capital letters, as it is considered shouting, and ensuring the subject of an email is directly related to its content for clarity.
