Explanation:
A blog is a type of website, usually maintained by an individual with regular entries of commentary, descriptions of events, or other material such as graphics or video. Entries are commonly displayed in reverse-chronological order. Blog can also be used as a verb, meaning to maintain or add content to a blog.Many blogs provide commentary or news on a particular subject; others function as more personal online diaries.
A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic. The ability of readers to leave comments in an interactive format is an important part of many blogs. Most blogs are primarily textual, although some focus on art (Art blog), photographs (photoblog), videos (Video blogging), music (MP3 blog), and audio (podcasting). Microblogging is another type of blogging, featuring very short posts.
A teleconference or teleseminar is the live exchange and mass articulation of information among several persons and machines remote from one another but linked by a telecommunications system. Terms such as audio conferencing, telephone conferencing and phone conferencing are also sometimes used to refer to teleconferencing. Internet teleconferencing includes internet telephone conferencing, videoconferencing, web conferencing, and Augmented Reality conferencing. E-mail (electronic mail) is a method of exchanging of computer-stored messages by telecommunication. E-mail messages are usually encoded in ASCII text. However, a user can also send non-text files, such as graphic images and sound files, as attachments sent in binary streams. E-mail was one of the first applications being made available on the Internet and is still the most popular one.
A large percentage of the total traffic over the Internet is of the e-mails. E-mails can also be exchanged between online service provider users and in networks other than the Internet, both public and private. E-mails can be distributed to lists of people as well as to individuals.
A shared distribution list can be managed by using an e-mail reflector. Some mailing lists allow you to subscribe by sending a request to the mailing list administrator.
A mailing list that is administered automaticallyis called a list server.E -mail is one of the protocols included with the Transport Control Protocol/Internet Protocol (TCP/IP) suite of protocols.
A popular protocol for sending e-mails is Simple Mail Transfer Protocol and a popular protocol for receiving it is POP3. Both Netscape and Microsoft include an e-mail utility with their Web browsers. Internet telephony refers to communication services such as voice, facsimile, and/or voice-messaging applications that are transported via the Internet, rather than the public switched telephone network (PSTN). The basic steps involved in originating an Internet telephone call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet; the process is reversed at the receiving end. Internet telephony involves conducting a teleconference over the Internet or a Wide Area Network. One key technology in this area is Voice over Internet Protocol (VOIP). Popular software for personal use include Skype, Google Talk, Vonage, Speakeasy, Windows Live Messenger and Yahoo Messenger. Instant messaging (IM) is a form of real-time direct text-based communication between two or more people using personal computers or other devices, along with shared software clients. The user's text is conveyed over a network, such as the Internet. More advanced instant messaging software clients also allow enhanced modes of communication, such as live voice or video calling.IM falls under the umbrella term online chat, as it is a real-time text-based networked communication system, but is distinct in that it is based on clients that facilitate connections between specified known users (often using Buddy List, Friend List or Contact List), whereas online 'chat' also includes web-based applications that allow communication between users in a multi-user environment.
Answer option C is incorrect. Post-it notes are not a type of electronic communications.
