本文向大家介绍网络布线中的对等网布线技巧,可能好多人还不了解对等网布线技巧,没有关系,看完本文你肯定有不少收获,会对对等网布线有一个充分的了解,也希望本文教会您更多的东西。
我们知道,计算机网络按其工作模式分主要有:对等模式和客户机/服务器(C/S)/模式,在家庭网络中通常采用对等腰网模式,而在企业网络中则通常采用C/S模式。因为对等腰三角形模式注重的是网络的共享功能,而企业网络更注重的是文件资源管理和系统资源安全等方面。对等网除了应用方面的特点外,更重要是的它的组建方式简单,投资成本低,非常容易组建,非常适合于家庭、小型企业选择使用。学习网络组建当然是从最基本的着手,而对等网是最简单的一种网络模式,它可以只需几条网线,加上几块网卡就可以,而这些知识我们在前面已作详细介绍,完全具备基本的对等组建能力。
一、对等网简介
“对等网”也称“工作组网”,那是因为它不像企业专业网络中那样是通过域来控制的,在对等网中没有“域”,只有“工作组”,这一点要首先清楚。正因如此,我们在后面的具体网络配置中,就没有域的配置,而需配置工作组。很显然,“工作组”的概念远没有“域”那么广,所以对等网所能随的用户数也是非常有限的。在对等网络中,计算机的数量通常不会超过20台,所以对等网络相对比较简单。在对等网络中,对等网上各台计算机的有相同的功能,无主从之分,网上任意节点计算机既可以作为网络服务器,为其它计算机提供资源;也可以作为工作站,以分享其它服务器的资源;任一台计算机均可同时兼作服务器和工作站,也可只作其中之一。同时,对等网除了共享文件之外,还可以共享打印机,对等网上的打印机可被网络上的任一节点使用,如同使用本地打印机一样方便。因为对等网不需要专门的服务器来做网络支持,也不需要其他组件来提高网络的性能,因而对等网络的价格相对要便宜很多。
对等网主要有如下特点:
(1)网络用户较少,一般在20台计算机以内,适合人员少,应用网络较多的中小企业;
(2)网络用户都处于同一区域中;
(3)对于网络来说,网络安全不是最重要的问题。
它的主要优点有:网络成本低、网络配置和维护简单。
它的缺点也相当明显的,主要有:网络性能较低、数据保密性差、文件管理分散、计算机资源占用大。
二、对等网结构
虽然对等网结构比较简单,但根据具体的应用环境和需求,对等网也因其规模和传输介质类型的不同,其实现的方式也有多种,下面分别介绍:
1、两台机的对等网布线技巧
这种对等网的组建方式比较多,在传输介质方面既可以采用双绞线,也可以使用同轴电缆,还可采用串、并行电缆。所需网络设备只需相应的网线或电缆和网卡,如果采用串、并行电缆还可省去网卡的投资,直接用串、并行电缆连接两台机即可,显然这是一种最廉价的对等网组建方式。这种方式中的“串/并行电缆”俗称“零调制解调器”,所以这种方式也称为“远程通信”领域。但这种采用串、并行电缆连接的网络的传输速率非常低,并且串、并行电缆制作比较麻烦,在网卡如此便宜的今天这种对等网连接方式比较少用。
2、三台机的对等网布线技巧
如果网络所连接的计算机不是2台,而是3台,则此时就不能采用串、并行电缆连接了,而必须采用双绞线或同轴电缆作为传输介质,而且网卡是不能少的。如果是采用双绞线作为传输介质,根据网络结构的不同又可有两种方式:
(1)一种是采用双网卡网桥方式,就是在其中一台计算机上安装两块网卡,另外两对路机各安装一块网卡,然后用双绞线连接起来,再进行有关的系统配置即可;
(2)添加一个集线器作为集结线设备,组建一个星形对等网,三台机都直接与集线器相连。从这种方式的特点来看,虽然可以省下一块网卡,但需要购买一个集线器,网络成本会较前一种高些,但性能要好许多。
如果采用同轴电缆作为传输介质,则不需要购买集线器了,只需把三台机用同轴电缆网线直接串连即可。虽然也只需3块网卡,但因同轴电缆较双绞线贵些,所以总的投资与用双绞线差不多。
3、多于3台机的对等网布线技巧
对于多于3台机的对等网组建方式只能有两种:
(1)采用集线设备(集线器或交换机)组成星形网络;
(2)用同轴电缆直接串连。虽然这类对等网也可采用双网卡网桥方式,就是在除了首、尾两台计算机外都采用双网卡配置,但这种方式因要购差不多两倍的网卡,成本较高;且双网卡配置对计算机硬件资源要求较高,所以不可能有人会用这种方式来实现多台计算机的对等网到连。
以上介绍是对等网的硬件配置,在软件系统方面,对等网布线技巧更是非灵活,几乎所有操作系统都可以配置对等网,包括网络专用的操作系统,如Windows NT Server/2000 Server/2003 Server,Windows 9x/ME/2000 Pro/XP等也都可以,早期的DOS系统也可以。
因为对等网类型繁多, 所用系统组成也是多种多样,不可能对所有类型的对等网组建方法都一一介绍,况且实际应用中有些对等网类型并不常用,如直接电缆连接的对等网、双网卡对等网等,在操作系统方面如DOS、Windows 95、Windows NT/2000/2003 Server等也通常不应用于对等网布线技巧中,所以在本篇仅介绍目前在家庭中常用的Windows 98及Windows 2000 Pro系统中双绞线两台机的对等网配置方法。多机及其它操作系统下对等网的配置方法类似,参照即可。
三、Windows 98与Windows 2000 Pro双机双绞线对等网组建
在整个组网过程中,总的来说可以分为如下几个大步:
(1) 网线制作;
(2) 网卡的硬件安装;
(3) 网卡的连接;
(4) 网卡驱动程序的安装与系统配置。

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
