This document summarizes key concepts about data communication including: 1) Data flow can occur in three ways - simplex, half duplex, and full duplex. Simplex allows transmission in one direction, half duplex allows transmission in both directions but not simultaneously, and full duplex allows simultaneous transmission in both directions. 2) There are two types of signals - analog and digital. An analog signal represents information as a continuously variable physical quantity while a digital signal represents information using discrete values. 3) An intranet is a private computer network that allows information and system sharing within an organization, while the Internet is the global network of billions of computers that connects people worldwide.

E-mail is a method for exchanging digital messages between an author and recipients over the Internet or other computer networks. It uses a store-and-forward model where email servers accept, forward, deliver, and store messages so that users do not need to be online simultaneously. An email message consists of an envelope, header, and body. Standards for encoding email were established in the 1970s and it has become a crucial communication technology carried over SMTP.

Electronic mail, commonly called email, allows digital messages to be exchanged between an author and one or more recipients over the internet or other computer networks. Email systems operate on a "store and forward" model where email servers accept, forward, deliver, and store messages so that users do not need to be online simultaneously. The basic components of an email message are the message envelope, header, and body. Originally supporting only text, email has been extended through standards to allow attachment of files and multimedia content.

E-learning uses computers and networks to provide educational content asynchronously or synchronously. Asynchronous learning allows for individual self-paced study, while synchronous options include video conferencing classes. E-learning systems consist of educational content, communication tools, and content management systems to organize materials. Content includes text, images, videos and interactive elements like quizzes. Communication tools facilitate discussion through wikis, bulletin boards, blogs and chats. Content management systems help manage these resources. While e-learning formats vary by browser, standards like MathML aim to represent mathematical expressions consistently across platforms.

An automatic filtering task in osn using content based approach
This document summarizes an academic paper on developing an automatic filtering system for online social networks using content-based approaches. It describes a three-tier architecture for the filtering system, with the lowest layer managing social networks, a middle layer performing message categorization and blacklisting, and a top layer providing a graphical user interface. The system works by intercepting messages, extracting metadata using machine learning classification, applying filtering and blacklisting rules, and publishing approved messages while filtering unwanted ones based on content and creator. It aims to allow users more control over messages on their walls by blocking offensive, political, or other undesirable content in an automatic way.

The document also examines common network topologies like bus, star, ring, mesh, tree, and hybrid along with their advantages and disadvantages. Finally, it briefly introduces some network technologies including intranets, extranets, and the internet.
Higher level internet protocols (ppt)
Email has evolved significantly since its invention in the 1960s. It started as a simple messaging system but grew to become the "killer app" of the internet due to its low cost, ease of use, and ability to be accessed from any device with connectivity. Key developments like SMTP, POP, IMAP, and MIME have allowed email to support attachments, non-text content, and interoperability across different service providers and devices. However, the openness of email has also enabled issues like spam and potential security risks to emerge.
Chapter – 1
Data communication involves transmitting data over communication lines like telephone or cable lines. The basic elements of any communication system are a sender who creates the message, a medium that transmits the message, and a receiver who receives the message. A computer network is a collection of connected computers and devices that allows users to communicate with each other and share resources. The main benefits of a computer network are communication between users anywhere in the world at low cost, sharing of resources like printers and scanners, sharing of software stored centrally, and sharing of data between authorized users on the network.
Computer mediated communication slide
The document defines computer-mediated communication (CMC) as communication that occurs between humans using computers. CMC takes place synchronously or asynchronously through various mediums like text, audio, or video. Synchronous CMC allows for real-time interaction through applications like instant messaging, Skype video calls, or chat rooms. Asynchronous CMC occurs over different times through email, online forums, text messages, or video sharing websites. The document discusses examples of synchronous and asynchronous applications and how CMC plays an important role in distance learning environments.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
