Network Devices 0:00-0:17 In addition to all the connectivity devices that make up a network's infrastructure, a network is also made up of devices that provide data functionality, or essential network services. The first such device is called a server. Servers 0:18-0:55 Computers on a network are referred to as hosts, and on a network there are two types of hosts.There are hosts that provide services such as data or security functions, and there are hosts that consume said services. As its name implies, a server is the type of host that provides a service to other hosts. It serves other hosts. Now, servers come in a lot of different shapes and sizes. Some servers even look like regular desktop computers. However, it's the internal functions and configurations that makes it a server, and there are actually different types of servers each of which provide various services to network hosts. File and Print Server 0:56-1:13

One type of server is a file and print server. File and print servers provide file sharing on a network.They allow other hosts to store and access files across the network. They also process network print jobs. If you've ever saved files on a network, or printed on a network, you've used a file and print server. Application Server 1:14-1:30 Another type of server is called an applications server. Application servers provide some sort of network application that can be used by hosts on a network. One common implementation is a database server, where hosts can read and write information to a network database. Directory Server 1:31-1:48 A directory server is another type of server that handles user authentication and information. If you've ever logged into Windows domain or an eDirectory tree, you've used a directory server to do so. Directory servers store user information, authentication information, user permissions, and user settings. Remote Access Server 1:49-2:07 Another type of server is a remote access server. As its name implies, remote access servers provide remote access to a work station within a network. For example if an employee is working from home,they can use a remote access server to connect to the work station and use internal network services. Web Server 2:08-2:21 Probably one of the most prolific types of servers is the web server. Web servers are used to provide websites via HTTP. Anytime you use the Internet and access a webpage, you are accessing a web server. DNS Server 2:22-2:42 Another common type of server is a domain name system, or a DNS server. The job of a DNS server is to map IP addresses to domain names. Remembering a domain name is a lot easier than an IP address. For example it's a lot easier to remember TestOut.com than the IP address associated with the web server.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
