Active Directory Functionality and Structure
Directory Service Functionality
Active Directory provides directory service functionality to organize, manage, and centrally control access to network resources.
It overlooks the physical network topology and protocols.
It is organized into sections allowing storage of numerous objects.
Active Directory can be extended as an organization grows.
It provides centralized access control with single sign-on.
Directory Service Objects
Objects represent network resources.
A single administrator controls resources

AWT, Applets, and Applications
The Abstract Window Toolkit (AWT) provides fundamental components for creating Graphical User Interfaces (GUIs) used in both Java applications and applets. A key advantage of AWT is its platform independence, ensuring consistent display across different operating systems and graphical interfaces.
AWT study strategy can be divided into:
- Components: Classes and interfaces for creating GUI objects like buttons, dropdown lists, text boxes, checkboxes, radio buttons, labels,
Telephone Network Components and Concepts
Central Types
Central Local (CL)
Connects subscribers within a defined geographic area.
Central Elementary (CP)
Interconnects local exchanges, linking to a higher-order central.
Central School (CS)
Connects primary centrals, linking to a higher-order central.
Central Tertiary or Nodal (CT)
High-power interconnects, linking to other tertiary plants. Only six exist.
Network Sections
Subscriber Line
Connects the terminal to the subscriber central.
Primary Section
Each union power circuit consists of individual

Von Neumann Computer Architecture
Overview
This architecture, conceptualized by John von Neumann, remains relevant today. It describes a computer system with interconnected functional units.
Functional Units
- Input Unit: Receives data and instructions, converting them into binary signals. Multiple input units can exist.
- Output Unit: Presents results to the user, transforming binary signals into understandable information.
- Internal Memory (Main/Central Memory): Stores data and instructions during program
Compiler Design and Implementation
Compiler Overview
A compiler translates a program written in one programming language into another. The target language is typically machine language, but it can also be another high-level language or even text. This translation process is called compilation.
Compilers allow developers to write programs in languages closer to human thought processes. These high-level programs are then compiled into a form more readily understood and executed by computers.
The Compilation Process
Compilation translates
