The following notes discuss integration, configuration, and types of reusable software including stand-alone application systems, collection of objects, and web services. In addition, it discusses ERP systems, COTS-solution, COTS-integrated systems, and the requirement engineering process,

The following notes discuss incremental development and software process descriptions including products, roles, and prior and post conditions. In addition, it discusses plan-driven processes, agile processes, and the waterfall model.

The following notes discuss frequently asked questions about software engineering including the key challenges faced, costs used, best software engineering techniques, and differences the web made to software engineering. In addition, it discusses software engineering diversity and application types including batch processing systems, entertainment systems, systems for modeling and simulation, data collection systems, and a system of systems.

The following notes discuss how professional software development differs from that in coursework, some failed and overbudgeted custom software projects, notable software failures, poor design choices, and major attributes of the four distinctive characteristics of software including acceptability, dependability, efficiency, and maintainability, and roles in a software project

The following notes discuss the definition of software engineering, goals, qualities of software that differ from that of traditional "engineered" products, broad and fundamental activities, comments, and reasons to why we need software engineering

The following notes discuss the architecture design model by prescription, design in the small, design in the larger, object-oriented modeling, etc. In addition, it discusses architectural patterns including master-slave architecture, two-tier client-server architecture, multi-tier client-server architecture, and distributed component architecture.

The following notes discuss routing. Routing is the process of finding the best path to send data from source to destination. It explains in detail what an autonomous system is. In addition, it discusses the similarities and differences between interior routing protocols and exterior routing protocols. Moreover, it discusses routing tables and how they work and operate to do their required tasks. Furthermore, it discusses topics in discrete structures such as Dijkstra's algorithm, a dynamic gra...

The following notes discuss the transport layer. The transport layer is the fourth layer of the OSI model and is responsible for providing logical communication between the processes of apps that operate on different hosts. The notes begin by discussing the transport layer in detail. In addition, it analyzes major transport layer protocols such as UDP, TCP, and NAT. It talks about port forwarding, a socket, the three-way handshake, and the four-way handshake.

The following notes discuss the network layer. It begins by discussing topics that will be covered later in the notes such as packet forwarding, end-to-end communication, the architecture of the Internet, and various routing protocols. In addition, it analyzes what a local area network is in detail. Moreover, it discusses the Internet Protocol which laid the foundation for communication across the network. Furthermore, it discusses classful addressing, classless interdomain routing (CIDR), the s...

The following notes discuss scopes and closures. It will analyze the three different types of scopes including lexical scope, global scope, and function scope. In addition, it discusses how data is represented in most programming languages. It will talk about other important things in JavaScript functions, the concept of memoization, and namespacing private functions. Moreover, it covers redundant concepts discussed in previous notes such as different types of variables and the difference betwee...
