Network operating systems (nos) routes and manages communications on the network and coordinates network resources. Key digital networking technologies: client/server computing, distributed computing model, packet switching, slicing digital messages into parcels, tcp/ip: transmission control protocol/internet protocol, dominant model for achieving connectivity among different networks. Signals are ways to communicate a message in a network. Analog signals: telephone line, cable system, wireless medial, analog device. Ways to connect to the internet: internet service provider (isp) or designate domain. Types of internet connections: dial-up, broadband, dsl, cable internet connection, satellite, t1/t3. Internet protocol (ip) address: every device connected to the internet must have a unique address number called an ip address. It is a 32-bit number represented by four strings of numbers ranging from 0-255 such as 207. 46. 250. 119. Domain name: english-like name that corresponds to the unique ip address for each computer connected to the internet.
