SBOLC NETWORK+ // NETWORK ESSENTIALS 3.15.2018 LATEST 2024 RATED A Workstations Workstations are often seriously powerful computers that run more than one central processing unit (CPU) and whose resources are available to other users on the network to access when needed. Client Machine A client machine is any device on the network that can ask for access to resources from a server or powerful workstation—that for instance, hosts a printer. Servers Servers are also powerful computers. They get their name because they truly are "at the service" of the network and run specialized software for the network's maintenance and control known as the network operating system. File server Stores and dispenses files Mail server The network's post office; handles email functions Print server Manages printers on the network Web server Manages web-based activities by running Hypertext Transfer Protocol (HTTP) for storing web content and accessing web pages Fax server The "memo maker" that sends and receives paperless faxes over the network Application server Manages network applications Telephony server Handles the call center and call routing and can be thought of as a sophisticated network answering machine Remote access server Provides remote users with access to the network through modems and an IP connection Proxy server Handles tasks in the place of other machines on the network Host The scope of possible machines and devices is so broad because, in TCP/IP-speak, host means any network device with an IP address. All computers connected to a network that participate directly in network communication are classified as hosts. Wide Area Network (WAN) Local Area Network (LAN) A local area network (LAN) is usually restricted to spanning a particular geographic location such as an office building, a single department within a corporate office, or even a home office. IPv4 address The IPv4 address is a logical network address that identifies a particular host. It is unique within the LAN. Every packet sent across the Internet has a source and destination IPv4 address An IPv4 address is simply a series of 32 binary bits (ones and zeros). 32 bits are grouped into four 8-bit bytes called octets 192.168.1.5 ....
