Forms
Computer-mediated communication can be broken down into two forms: synchronous and asynchronous. Synchronous computer-mediated communication refers to communication that occurs in real-time. All parties are engaged in the communication simultaneously; however, they are not necessarily all in the same location.
Examples of synchronous communication are video chats and FaceTime audio calls. On the contrary, asynchronous computer-mediated communication refers to communication that takes place when the parties engaged are not communicating in unison. In other words, the sender does not receive an immediate response from the receiver. Most forms of computer-mediated technology are asynchronous.
Examples of asynchronous communication are

Characteristics
Communication occurring within a computer-mediated format has an effect on many different aspects of an interaction. Some of those that have received attention in the scholarly literature include impression formation, deception, group dynamics, disclosure reciprocity, disinhibition and especially relationship formation.
CMC is examined and compared to other communication media through a number of aspects thought to be universal to all forms of communication, including (but not limited to)
synchronicity,
persistence or "recordability", and
anonymity
Anonymity describes situations where the acting person's identity is unknown. Some writers have argued that namelessness, though technically correct, does not capture what is more centrally at stake in contexts of anonymity. The important idea he ...
. The association of these aspects with different forms of communication varies widely. For example,

is intrinsically synchronous but not persistent, since one loses all the content when one closes the dialog box unless one has a message log set up or has manually copy-pasted the conversation. E-mail and message boards, on the other hand, are low in synchronicity since response time varies, but high in persistence since messages sent and received are saved. Properties that separate CMC from other media also include transience, its
multimodal nature, and its relative lack of governing codes of conduct. CMC is able to overcome physical and social limitations of other forms of communication and therefore allow the interaction of people who are not physically sharing the same space.
Technology would be a powerful tool when defining communication as a learning process that needs a sender and receiver.
According to Nicholas Jankowski in his book The Contours of Multimedia, a third party, like software, acts in the middle between a sender and receiver. The sender is interacting with this third party to send. The receiver interacts with it as well, creating an additional interaction with the medium itself along with the initially intended one between sender and receiver.
The medium in which people choose to communicate influences the extent to which people disclose personal information. CMC is marked by higher levels of self-disclosure in conversation as opposed to face-to-face interactions.
Self disclosure is any verbal communication of personally relevant information, thought, and feeling which establishes and maintains interpersonal relationships.
This is due in part to visual anonymity and the absence of nonverbal cues which reduce concern for losing positive
face. According to Walther’s (1996)
hyperpersonal communication model, computer-mediated communication is valuable in providing a better communication and better first impressions.
Moreover, Ramirez and Zhang (2007) indicate that computer-mediated communication allows more closeness and attraction between two individuals than a face-to-face communication. Online impression management, self-disclosure, attentiveness, expressivity, composure and other skills contribute to competence in computer mediated communication. In fact, there is a considerable correspondence of skills in computer-mediated and face-to-face interaction even though there is great diversity of online communication tools.
Anonymity and in part privacy and security depends more on the context and particular program being used or web page being visited. However, most researchers in the field acknowledge the importance of considering the psychological and social implications of these factors alongside the technical "limitations".
Language learning
CMC is widely discussed in language learning because CMC provides opportunities for language learners to practice their language. For example, Warschauer conducted several case studies on using email or discussion boards in different language classes. Warschauer claimed that information and communications technology “bridge the historic divide between speech...and writing”. Thus, considerable concern has arisen over the reading and writing research in
L2 due to the booming of the Internet. In the learning process, students, especially kids, need cognitive learning, but they also need social interaction, which enhances their psychological needs. Although technology has its powerful effect in assisting the English language learners to learn, it can not be a comprehensive way that covers different aspects of the learning process.
Benefits
The nature of CMC means that it is easy for individuals to engage in communication with others regardless of time, location, or other spatial constraints to communication. In that CMC allows for individuals to collaborate on projects that would otherwise be impossible due to such factors as geography, it has enhanced social interaction not only between individuals but also in working life. In addition, CMC can also be useful for allowing individuals who might be intimidated due to factors like character or disabilities to participate in commu
