Study Notes
Managed Code
- Managed code is code that runs on top of the Common Language Runtime (CLR)
- The CLR provides services like garbage collection and security
- It ensures that an application can only access the memory it's authorized to access.
Network Communication
- Two different types of computers can transmit information if they both use the TCP/IP protocol
- The TCP/IP model is divided into four layers: Application, Transport, Internet, and Network Access
- The Internet layer of the TCP/IP model includes protocols like IP and ARP
.NET Framework
- The core components of the .NET Framework are the Common Language Runtime(CLR), the Framework Class Library, and ASP.NET Applications
- The CLR is a runtime environment that manages the execution of .NET applications.
- The Framework Class Library is a collection of reusable classes that can be used by .NET applications.
- ASP.NET Applications are web applications that can be developed using the .NET Framework.
C# Programming
- The keyword "int" in C# maps to the .NET type System.Int32
- The keyword "using" in C# states that the program is using the names in the given namespace
- A namespace in C# helps keep sets of names separate from each other, preventing naming conflicts.
- The C# keyword "endregion" marks the end of a #region block
- There are several different ways to declare two-dimensional integer arrays in C#:
-
Int[][] myArray;
-
Int[,] myArray;
-
Networking
- The Presentation layer in the OSI model uses the data unit called "Data"
- The Network layer in the OSI model performs route selection and information forwarding
- The Transport layer of the TCP/IP model includes protocols like TCP and UDP
- The TCP protocol provides highly reliable packet transport, while UDP provides less reliable, but faster packet transport
- The ARP protocol is used to map IP addresses to physical MAC addresses
- The Ping utility in TCP/IP is used to test network connectivity
- The OSI model organizes communication protocols into 7 layers:
- Application
- Presentation
- Session
- Transport
- Network
- Data Link
- Physical
Miscellaneous
- The Garbage Collector in .NET is responsible for freeing memory occupied by unreferenced objects, avoiding memory leaks.
- The Main() method is the entry point for a C# program.
- C# exceptions occur at runtime.
- The Common Language Runtime (CLR) provides services to run both "managed" and "unmanaged" applications.
- The "ToString()" method converts a type to a string in C#.
BOPPPS
- BOPPPS is a teaching and learning framework acronym for:
- Bridge
- Objectives
- Pre-assessment
- Participatory Learning
- Post-assessment
- Summary
BOPPPS Element Descriptions
- The bridge element can be used to tell a story, use a current event, or ask a question to capture the learner's attention.
- The objectives element describes the student's learning outcomes in terms of observable behaviors.
- The pre-assessment element helps the teacher to determine the learner's prior knowledge, skills, and attitudes related to the topic.
- The participatory learning element involves activities where learners actively engage with information and concepts.
- The post-assessment element can be used to check for student understanding and evaluate instruction.
- The summary element emphasizes the key points of the lesson, connects the lesson to future lessons, and provides actionable steps for learners to apply their new knowledge.
