The document provides an overview of the basic features of Oracle, including:
- Oracle consists of an Oracle database and Oracle server instance, with SQL as the programming language.
- The database has both a physical structure of datafiles, redo logs, and control files, and a logical structure of tablespaces and schema objects.
- An Oracle instance includes background processes and a shared memory area (SGA) containing buffers, redo logs, and the shared pool.
- SQL and PL/SQL allow querying and manipulating the database, with PL/SQL adding programming functionality. Background processes manage I/O, recovery, and other maintenance tasks.Chapter 6-Remoting

EIGRP is an enhanced version of IGRP that provides faster convergence times and greater efficiency. It uses the same distance vector routing protocol as IGRP but improves on it with technologies like DUAL and reliable transport. EIGRP supports various network layers, has capabilities for neighbor discovery, route tagging for external routes, and operates in a way that ensures rapid synchronization across all routers during topology changes.MySQL-PHP

This document provides an overview and introduction to the book "MySQL/PHP Database Applications" by Jay Greenspan and Brad Bulger. It discusses what the book covers, how it is organized, who it is intended for, and what readers can expect to learn. The book focuses on using PHP and MySQL together to develop data-driven web applications. It is intended for developers who want to learn how to efficiently build these types of applications. The book is organized into four parts that cover using MySQL, using PHP, building simple applications, and constructing more complex, real-world types of applications commonly found on the web.RTS introduction

This document describes the Routing Information Protocol (RIP), which is used to exchange routing information between gateways and hosts. It aims to formally document the protocol, which was previously undocumented but widely used. The document specifies improvements to the distance vector routing algorithms to improve stability in large networks, and suggests optional features to increase configurability and control. RIP is intended for use within autonomous systems to exchange routing information.Enhanced Interior Gateway Routing Protocol - Wikipedia, the free encyclopedia

EIGRP is a proprietary routing protocol developed by Cisco that is based on distance-vector routing. It uses the Diffusing Update Algorithm to quickly converge on routes and prevent routing loops. EIGRP calculates composite metrics for routes using factors like bandwidth and delay to determine the best path. It elects successors and feasible successors for routes to provide primary and backup paths. EIGRP also uses neighbor tables, topology tables, and routing tables to store routing information and make forwarding decisions.Phan tich QL ban va mua hang

EIGRP is an enhanced version of IGRP that provides faster convergence times and greater efficiency. It uses the same distance vector routing protocol as IGRP but improves on it with technologies like DUAL and reliable transport. EIGRP supports various network layers, has capabilities for neighbor discovery, route tagging for external routes, and operates in a way that ensures rapid synchronization across all routers during topology changes.MySQL-PHP

This document provides an overview and introduction to the book "MySQL/PHP Database Applications" by Jay Greenspan and Brad Bulger. It discusses what the book covers, how it is organized, who it is intended for, and what readers can expect to learn. The book focuses on using PHP and MySQL together to develop data-driven web applications. It is intended for developers who want to learn how to efficiently build these types of applications. The book is organized into four parts that cover using MySQL, using PHP, building simple applications, and constructing more complex, real-world types of applications commonly found on the web.RTS introduction

This document provides instructions for a lab exercise to configure Secure Shell (SSH) and Hypertext Transfer Protocol Secure (HTTPS) access on a Cisco IOS router. The lab objectives are to learn how to enable SSH and HTTPS to remotely manage the router securely. The tasks include configuring the router's hostname and IP address, generating an RSA key, enabling HTTPS with access control, configuring authentication using usernames/passwords, and verifying the configurations.Quan ly bo nho trong C#

This document describes the Routing Information Protocol (RIP), which is used to exchange routing information between gateways and hosts. It aims to formally document the protocol, which was previously undocumented but widely used. The document specifies improvements to the distance vector routing algorithms to improve stability in large networks, and suggests optional features to increase configurability and control. RIP is intended for use within autonomous systems to exchange routing information.Enhanced Interior Gateway Routing Protocol - Wikipedia, the free encyclopedia

EIGRP is a proprietary routing protocol developed by Cisco that is based on distance-vector routing. It uses the Diffusing Update Algorithm to quickly converge on routes and prevent routing loops. EIGRP calculates composite metrics for routes using factors like bandwidth and delay to determine the best path. It elects successors and feasible successors for routes to provide primary and backup paths. EIGRP also uses neighbor tables, topology tables, and routing tables to store routing information and make forwarding decisions.Phan tich QL ban va mua hang
