Client-Server Architecture and Software Licenses: An Overview

Client-Server Architecture

Overview

The client-server model aims to provide usability, flexibility, scalability, interoperability, and effective communication. It’s an extension of modular programming where software modules are separated for easier development and maintenance.

Client (Front-End)

The client process allows users to formulate requests and send them to the server. Its functions include:

  • Managing the user interface
  • Interacting with the user
  • Processing application logic and performing local

Oracle Database Administration: Concepts and Best Practices

Oracle Database Administration

1. Data Block Size

The typical size of a data block ranges from 8 to 32KB, but we have observed sizes from 2 to 32KB.

2. Tablespace Usage

A tablespace is used to store: c) Data logically

3. System Tablespace

The system tablespace: b) Stores data dictionary information

4. Oracle Segment Types

Segments that exist in Oracle include: c) Temporary and Rollback

5. Oracle Extents

Extents in Oracle are utilized to: c) Monitor tablespace size

6. PCTFREE Parameter

The PCTFREE parameter

Space UNDO

Handles system failures and ensures read consistency. Rollback transactions are managed through this space. The UNDO_MANAGEMENT initialization parameter must be set to AUTO.

ALTER ROLLBACK SEGMENT <NAME>
STORAGE (INITIAL <XX>
NEXT <XX>
MINEXTENTS <XX>
MAXEXTENTS <XX>
OPTIMAL <XX>);

Default Tablespace

Indicates the storage space where schema objects are created by the user when no specific tablespace is defined. If no tablespace is specified, the SYSTEM tablespace

Microprocessor Addressing Modes, Flag Register, and Bus Types

Microprocessor Addressing Modes

Addressing modes determine how the microprocessor accesses data during instruction execution. Here are the common addressing modes:

Immediate Addressing

In immediate addressing mode, the data is specified directly within the instruction itself. This data becomes part of the program instruction. Instructions with ‘I’ in their mnemonics typically use immediate addressing. For example:

MVI B, 3EH – Move the data 3EH (given in the instruction) to the B register.

Register Addressing
