id="1QIB73SQ"><br/>(一)什么是服务器？<br/>在技术意义上，服务器是计算机程序或设备的实例（本质可以说是一种计算机），用于处理请求并通过Internet或本地网络将数据传送到另一台计算机。<br/>服务器用于做什么的？<br/>服务器是用于管理网络资源。例如，用户可以设置服务器以控制对网络的访问，发送/接收电子邮件，管理打印作业或托管网站。他们也擅长执行激烈的计算。某些服务器还致力于特定任务，通常称为专用任务。但是，如今的许多服务器都是共享服务器，在Web服务器的情况下，它们可以承担电子邮件，DNS，FTP甚至多个网站的责任。<br/>(二)服务器的特殊特性和功能<br/>几乎所有个人计算机都能够充当网络服务器。但是，通常软件或硬件系统专用计算机具有仅用于此任务的功能和配置。例如，专用服务器可能具有高性能RAM，更快的处理器和多个高容量硬盘驱动器。此外，专用服务器可以连接到冗余电源，多个网络和其他服务器。这种连接特征和配置是必要的，因为许多客户端机器和客户端程序可能依赖于它们来有效，正确和可靠地运行。<br/>为了在许多计算机和硬件或软件系统仅依赖于一台或多台服务器计算机的独特网络环境中运行，服务器通常具有特殊的特性和功能，包括：<br/>1、无需重启或重启即可更新硬件和软件的能力。<br/>2、高级备份功能，可频繁备份关键数据。<br/>3、高级网络性能。<br/>4、设备之间自动（用户不可见）数据传输。<br/>5、高度安全的资源，数据和内存保护。<br/>(三)常见的服务器类型<br/>计算机可能需要许多服务才能工作。因此，有不同类型的服务器可用。常见的服务器类型有:<br/>Web服务器<br/>Web服务器通过Web浏览器显示页面和运行应用程序。我们的浏览器现在连接的服务器就是一个Web服务器，它提供此页面以及您在其上看到的任何图像。在这种情况下，客户端程序很可能是Internet Explorer，Chrome，Firefox，Opera或Safari等浏览器。除了提供简单的文本和图像之外，Web服务器还可用于各种事务，例如通过云存储服务 或在线备份服务在线上载和备份文件 。<br/>电子邮件服务器<br/>电子邮件服务器便于发送和接收电子邮件。如果我们的计算机上有电子邮件客户端，则该软件将连接到IMAP或POP电子邮件服务器以将邮件下载到您的计算机，而SMTP服务器则通过电子邮件服务器发回邮件。<br/>FTP服务器<br/>FTP服务器支持通过文件传输协议工具移动文件。FTP服务器可通过FTP客户端程序远程访问。<br/>Identity服务器<br/>Identity服务器支持授权用户的登录和安全角色。<br/>杭州高防护段展示：<br/>43.227.221.1<br/>43.227.221.2<br/>43.227.221.3<br/>43.227.221.4<br/>43.227.221.5<br/>43.227.221.6<br/>43.227.221.7<br/>43.227.221.8<br/>43.227.221.9<br/>43.227.221.10<br/>43.227.221.11<br/>43.227.221.12<br/>43.227.221.13<br/>43.227.221.14<br/>43.227.221.15<br/>43.227.221.16<br/>43.227.221.17<br/>43.227.221.18<br/>43.227.221.19<br/>43.227.221.20<br/>43.227.221.21<br/>43.227.221.22<br/>43.227.221.23<br/>43.227.221.24<br/>43.227.221.25<br/>43.227.221.26<br/>43.227.221.27<br/>43.227.221.28<br/>43.227.221.29<br/>43.227.221.30<br/>43.227.221.31<br/>43.227.221.32<br/>43.227.221.33<br/>43.227.221.34<br/>43.227.221.35<br/>43.227.221.36<br/>43.227.221.37<br/>43.227.221.38<br/>43.227.221.39<br/>43.227.221.40<br/>43.227.221.41<br/>43.227.221.42<br/>43.227.221.43<br/>43.227.221.44<br/>43.227.221.45<br/>43.227.221.46<br/>43.227.221.47<br/>43.227.221.48<br/>43.227.221.49<br/>43.227.221.50<br/>43.227.221.51<br/>43.227.221.52<br/>43.227.221.53<br/>43.227.221.54<br/>43.227.221.55<br/>43.227.221.56<br/>43.227.221.57<br/>43.227.221.58<br/>43.227.221.59<br/>43.227.221.60<br/>43.227.221.61<br/>43.227.221.62<br/>43.227.221.63<br/>43.227.221.64<br/>43.227.221.65<br/>43.227.221.66<br/>43.227.221.67<br/>43.227.221.68<br/>43.227.221.69<br/>43.227.221.70<br/>43.227.221.71<br/>43.227.221.72<br/>43.227.221.73<br/>43.227.221.74<br/>43.227.221.75<br/>43.227.221.76<br/>43.227.221.77<br/>43.227.221.78<br/>43.227.221.79<br/>43.227.221.80<br/>43.227.221.81<br/>43.227.221.82<br/>43.227.221.83<br/>43.227.221.84<br/>43.227.221.85<br/>43.227.221.86<br/>43.227.221.87<br/>43.227.221.88<br/>43.227.221.89<br/>43.227.221.90<br/>43.227.221.91<br/>43.227.221.92<br/>43.227.221.93<br/>43.227.221.94<br/>43.227.221.95<br/>43.227.221.96<br/>43.227.221.97<br/>43.227.221.98<br/>43.227.221.99<br/>43.227.221.100<br/>43.227.221.101<br/>43.227.221.102<br/>43.227.221.103<br/>43.227.221.104<br/>43.227.221.105<br/>43.227.221.106<br/>43.227.221.107<br/>43.227.221.108<br/>43.227.221.109<br/>43.227.221.110<br/>43.227.221.111<br/>43.227.221.112<br/>43.227.221.113<br/>43.227.221.114<br/>43.227.221.115<br/>43.227.221.116<br/>43.227.221.117<br/>43.227.221.118<br/>43.227.221.119<br/>43.227.221.120<br/>43.227.221.121<br/>43.227.221.122<br/>43.227.221.123<br/>43.227.221.124<br/>43.227.221.125<br/>43.227.221.126<br/>43.227.221.127<br/>43.227.221.128<br/>43.227.221.129<br/>43.227.221.130<br/>43.227.221.131<br/>43.227.221.132<br/>43.227.221.133<br/>43.227.221.134<br/>43.227.221.135<br/>43.227.221.136<br/>43.227.221.137<br/>43.227.221.138<br/>43.227.221.139<br/>43.227.221.140<br/>43.227.221.141<br/>43.227.221.142<br/>43.227.221.143<br/>43.227.221.144<br/>43.227.221.145<br/>43.227.221.146<br/>43.227.221.147<br/>43.227.221.148<br/>43.227.221.149<br/>43.227.221.150<br/>43.227.221.151<br/>43.227.221.152<br/>43.227.221.153<br/>43.227.221.154<br/>43.227.221.155<br/>43.227.221.156<br/>43.227.221.157<br/>43.227.221.158<br/>43.227.221.159<br/>43.227.221.160<br/>43.227.221.161<br/>43.227.221.162<br/>43.227.221.163<br/>43.227.221.164<br/>43.227.221.165<br/>43.227.221.166<br/>43.227.221.167<br/>43.227.221.168<br/>43.227.221.169<br/>43.227.221.170<br/>43.227.221.171<br/>43.227.221.172<br/>43.227.221.173<br/>43.227.221.174<br/>43.227.221.175<br/>43.227.221.176<br/>43.227.221.177<br/>43.227.221.178<br/>43.227.221.179<br/>43.227.221.180<br/>43.227.221.181<br/>43.227.221.182<br/>43.227.221.183<br/>43.227.221.184<br/>43.227.221.185<br/>43.227.221.186<br/>43.227.221.187<br/>43.227.221.188<br/>43.227.221.189<br/>43.227.221.190<br/>43.227.221.191<br/>43.227.221.192<br/>43.227.221.193<br/>43.227.221.194<br/>43.227.221.195<br/>43.227.221.196<br/>43.227.221.197<br/>43.227.221.198<br/>43.227.221.199<br/>43.227.221.200<br/>43.227.221.201<br/>43.227.221.202<br/>43.227.221.203<br/>43.227.221.204<br/>43.227.221.205<br/>43.227.221.206<br/>43.227.221.207<br/>43.227.221.208<br/>43.227.221.209<br/>43.227.221.210<br/>43.227.221.211<br/>43.227.221.212<br/>43.227.221.213<br/>43.227.221.214<br/>43.227.221.215<br/>43.227.221.216<br/>43.227.221.217<br/>43.227.221.218<br/>43.227.221.219<br/>43.227.221.220<br/>43.227.221.221<br/>43.227.221.222<br/>43.227.221.223<br/>43.227.221.224<br/>43.227.221.225<br/>43.227.221.226<br/>43.227.221.227<br/>43.227.221.228<br/>43.227.221.229<br/>43.227.221.230<br/>43.227.221.231<br/>43.227.221.232<br/>43.227.221.233<br/>43.227.221.234<br/>43.227.221.235<br/>43.227.221.236<br/>43.227.221.237<br/>43.227.221.238<br/>43.227.221.239<br/>43.227.221.240<br/>43.227.221.241<br/>43.227.221.242<br/>43.227.221.243<br/>43.227.221.244<br/>43.227.221.245<br/>43.227.221.246<br/>43.227.221.247<br/>43.227.221.248<br/>43.227.221.249<br/>43.227.221.250<br/>43.227.221.251<br/>43.227.221.252<br/>43.227.221.253<br/>43.227.221.254<br/>43.227.221.255</p>
