3-Tier Architecture
In 3-tier Client/Server systems, the application logic resides in the middle tier, separate from the data and user interface. Theoretically, 3-tier systems are more scalable, robust, and flexible.
Example: TP monitor, Web.
2-Tier Architecture
In 2-tier Client/Server systems, the application logic is embedded in the client’s user interface or the server’s database.
Example: File servers and database servers with stored procedures.
Load Balancing

What is the Purpose and Application of DBMS?
Purpose of DBMS:
A Database Management System (DBMS) is software designed for efficient data storage, retrieval, and management. It provides users and applications with secure, organized, and efficient data access.
Applications of DBMS:
- Banking: Banks utilize DBMS for managing customer accounts, transactions, and loans.
- Education: Schools and universities employ DBMS to store student information, exam results, and course registrations.
- E-commerce: Online stores
Routing Algorithms and Network Layer Design: A Comprehensive Guide
Routing Algorithms in a Single Network
A routing algorithm is a procedure that determines the path for transferring data packets from a source to a destination. These algorithms play a crucial role in directing internet traffic efficiently. When a data packet leaves its source, it can potentially traverse numerous paths to reach its destination. Routing algorithms employ mathematical computations to identify the optimal path, often referred to as the “least-cost path,” for routing the packet.

Installation and Configuration for Services
Introduction
A protocol is needed to make operations transparent to the user, without requiring knowledge of the file systems used by networked computers, giving the impression of local operation. The FTP protocol handles this task by establishing a double TCP connection:
- Control Connection: Typically uses server port 21 for accessing and specifying client operations.
- Data Connection: Uses server port 20 for transferring files to or from the server.
An FTP

1) What are the Ethics to be Followed in Software Engineering?
Public Interest
Software engineers should always prioritize the safety, well-being, and privacy of the public. They must ensure that their work benefits society and avoids harm.
Client and Employer Confidentiality
Engineers must maintain the confidentiality of any information related to their client or employer and should not disclose it without permission unless legally required.
Product Quality
Software engineers must strive to deliver high-

SAP 1 Computer: Architecture and Comparison with SAP 2
SAP (Simple As Possible) computers are basic models used to illustrate computer architecture. SAP 1 and SAP 2 are educational tools that demonstrate the fundamentals of computer operation. SAP 1 has a simple design, while SAP 2 offers greater complexity and functionality.
Components of SAP 1 Computer
- Input Device (Switches or Keypad): Provides instructions and data (in binary/machine code) to the computer.
- Program Counter (PC): A 4-bit register
