CTS - Common Type System - It is at the core of .NET Framework's cross-language integration, type safety, and high-performance code execution. It defines a common set of types that can be used with many different language syntaxes. Each language (C#, VB.NET, Managed C++, and so on) is free to define any syntax it wishes, but if that language is built on the CLR, it will use at least some of the types defined by the CTS.

DISCO - Discovery of Web Services. A Web Service has one or more. DISCO files that contain information on how to access its WSDL.
DLL - Dynamic Link Library - a shared reusable library, that exposes an interface of usable methods within it.

HTTP - Hyper Text Transfer Protocol - is a communication protocol used to transfer information in the internet. HTTP is a request-response protocol between servers and clients.
IDE - Integrated Development Environment - is a development environment with source code editor with a compiler(or interpretor), debugging tools, designer, solution explorer, property window, object explorer etc.
IDL - Interface Definition Language - is a language for defining software components interface.
ILDASM - Intermediate Language Disassembler - The contents of an assembly may be viewed using the ILDASM utility, that comes with the .NET SDK or the Visual Studio.NET. The ildasm.exe tool may also be used in the command line compiler.
IIS - Internet Information Server - Is a server that provides services to websites and even hosts websites.
IL - Intermediate Language - is the compiled form of the .NET language source code. When .NET source code is compiled by the language specific compiler (say we compile C# code using csc.exe), it is compiled to a .NET binary, which is platform independent, and is called Intermediate Language code. The .NET binary also comprises of metadata.
JIT - Just in Time (Jitter) - is a technology for boosting the runtime performance of a system. It converts during runtime, code from one format into another, just like IL into native machine code. Note that JIT compilation is processor specific. Say a processor is X86 based, then the JIT compilation will be for this type of processor.
MBR - MarshallByReference - The caller recieves a proxy to the remote object.
MBV - MarshallByValue - The caller recieves a copy of the object in its own application domain.
MDI - Multiple Document Interface - A window that resides under a single parent window.
MSIL - Microsoft Intermediate Language - now called CIL.
Orcas - Codename for Visual Studio 2008
PE - Portable Executable - an exe format file that is portable.
RAD - Rapid Application Development
RCW - Runtime Callable Wrapper - This component is used when a .NET needs to use a COM component.
