ccna 200 301 syllabus definition in spanish.perform a single task, you will get better performance. The following servers typically provide only one service.File servers store and distribute files. Mail servers Post offices in a network that provide e-mail functions. A print server manages all printing tasks in the network. A Web server manages Web-based behavior by running HTTP (Hypertext Transfer Protocol) to store Webitems and accessing Web pages. Fax servers send and receive paperless fax documents over the network. Application servers manage web applications. The Telephony Communications Server manages call centers and call routing and can be thought of as a complex network answering machine. A remote access server provides network access to remote users over a modem, IP connection, or wireless connection.Proxy servers provide services in place of other devices in the network.Now, the idea of the Cisco Unified Communication System (UCS, Unified Communication System ) is to virtualize these servers, running multiple server applications on one powerful machine. This part is discussed in depth in my new book!As mentioned earlier, in this book you can think of servers as network devices that usually provide only one important function. But it's also important to remember that sometimes they are responsible for multiple tasks. Whether servers provide only one service or perform multiple network jobs, they will always maintain the integrity of network data by backing up the network's software and hardware.Back to Figure 1.2, which shows the two simplest examples of LAN networks. You must know that servers must have a large amount of hard disk space-much more than the capacity of a single workstation-because they will serve many clients and provide any resources that the clients request. Because servers are so important, you should place them in a very secure area. My company's servers are housed in a locked server room, not only because they are expensive, heavy-duty machines, but also because they store a lot of important and sensitive corporate data, so they need to be placed in a secure area to prevent unauthorized access.The network shown in Figure 1.4 contains workstations and servers; the hosts can access the servers over the network-that's the basic idea behind building a network.You probably noticed that there are more workstations than servers in this example, didn't you? If your answer is "because a server can serve a large number of users at the same time, but a workstation can't," then you're right!Mainframe
