This course provides a deep understanding of engineering systems at a level intended for research on complex engineering systems. It provides a review and extension of what is known about system architecture and complexity from a theoretical point of view while examining the origins of and recent developments in the field. The class considers how and where the theory has been applied, and uses key analytical methods proposed. Students examine the level of observational (qualitative and quantitative) understanding necessary for successful use of the theoretical framework for a specific engineering system. Case studies apply the theory and principles to engineering systems.

Life as an emergent property of networks of chemical reactions involving proteins and nucleic acids. Mathematical theories of metabolism, gene regulation, signal transduction, chemotaxis, excitability, motility, mitosis, development, and immunity. Applications to directed molecular evolution, DNA computing, and metabolic and genetic engineering.

This course provides an introduction to the technology and policy context of public communications networks, through critical discussion of current issues in communications policy and their historical roots. The course focuses on underlying rationales and models for government involvement and the complex dynamics introduced by co-evolving technologies, industry structure, and public policy objectives. Cases drawn from cellular, fixed-line, and Internet applications include evolution of spectrum policy and current proposals for reform; the migration to broadband and implications for universal service policies; and property rights associated with digital content. The course lays a foundation for thesis research in this domain.

How does the global network infrastructure work and what are the design principles on which it is based? In what ways are these design principles compromised in practice? How do we make it work better in today’s world? How do we ensure that it will work well in the future in the face of rapidly growing scale and heterogeneity? And how should Internet applications be written, so they can obtain the best possible performance both for themselves and for others using the infrastructure? These are some issues that are grappled with in this course. The course will focus on the design, implementation, analysis, and evaluation of large-scale networked systems.
Topics include internetworking philosophies, unicast and multicast routing, congestion control, network quality of service, mobile networking, router architectures, network-aware applications, content dissemination systems, network security, and performance issues. Material for the course will be drawn from research papers, industry white papers, and Internet RFCs.

In the year 1970’s when relational database came into picture, data schema to be worked upon were reasonably elemental and simple wherein the data items were to be arranged as a set of formally described tables with rows and columns. But with the need to store volumes and variety of data (unstructured) in recent years, non-relational database technologies            (document-oriented, graph based, column based, key-value and hybrid) have emerged to address the requirement that allow data to be grouped together more naturally and logically. One of the most popular ways of storing data is a document-oriented database, basically employed for storing, managing and retrieval of semi-structured data where each record and its associated data is considered of as a “document”. A document-oriented database is also termed as a document store or simple document, is one of the kind of NoSQL database. 

This website is a comprehensive look at digital citizenship for K-12 students, parents and teachers. It covers a wide variety of topics including: online security, online relationships and cyberbullying, digital footprint, digital citizenship, the use of copyrighted information and much more.

6.857 Network and Computer Security is an upper-level undergraduate, first-year graduate course on network and computer security. It fits within the Computer Systems and Architecture Engineering concentration.

This seminar is a space for collaborative inquiry into the relationships between social movements and the media. We’ll review these relationships through the lens of social movement theory, and function as a workshop to develop student projects. Seminar participants will work together to explore frameworks, methods, and tools for understanding networked social movements in the digital media ecology. We will engage with social movement studies as a body of theoretical and empirical work, and learn about key concepts including: resource mobilization; political process; framing; New Social Movements; collective identity; tactical media; protest cycles; movement structure; and more. We’ll explore methods of social movement investigation, examine new data sources and tools for movement analysis, and grapple with recent innovations in social movement theory and research. Assignments include short blog posts, a book review, co-facilitation of a seminar discussion, and a final research project focused on social movement media practices in comparative perspective.

Are you struggling with internet breakdown? If you are using your friend’s Wi-Fi to find out how to fix the internet, you are exactly where you should be. This is a complete guide about resolving the issues that break down the internet connection.

This content enable the learner to understand about the network layers in detail.

With the expansion of huge and complex real time data that is wandering across the internet today, the dimensions of data transmitted are escalating exponentially with each passing years. This makes working with standard database systems or on personal computers difficult because of its inability to handle outsized, unstructured and complicated data. Various institutes stores and uses massive amounts of data which are further utilized for generating reports to guarantee stability regarding the services they proposes. However, the challenge is how to analyze, capture, share, store, transfer, visualize, query, update and finally manipulate an impressive volume of data that has to be delivered through the internet to reach its destination intact maintaining its information privacy. Almost all the applications developed using any programming languages requires some external component to store and access data. The components for the same could be a local network, a cloud file or even a database. While sources like the network and cloud file systems store the unstructured data, the structured data is usually stored in a typical Relational Database Management System or RDBMS. The RDBMS operates with relational data model using schema for storing data into tables and is usually queried with SQL (Structured Query Language) for data operations. Usually it’s a time consuming process to define, structure, distribute and access data from RDBMS through SQL and hence, an alternative was developed for this called the NoSQL ("Non SQL", "Non relational" or "Not only SQL") database. This edited book chapter provides NoSQL databases hands on and attention has been paid to various types of NoSQL databases focusing on the details such as installation, creation, modification and various updation of one database belonging to each type.

This class is an applications-oriented course covering the modeling of large-scale systems in decision-making domains and the optimization of such systems using state-of-the-art optimization tools. Application domains include: transportation and logistics planning, pattern classification and image processing, data mining, design of structures, scheduling in large systems, supply-chain management, financial engineering, and telecommunications systems planning. Modeling tools and techniques include linear, network, discrete and nonlinear optimization, heuristic methods, sensitivity and post-optimality analysis, decomposition methods for large-scale systems, and stochastic optimization.
This course was also taught as part of the Singapore-MIT Alliance (SMA) programme as course number SMA 5223 (System Optimisation: Models and Computation).
