The first computer networks were links between physical workstations, personal and desktop computers either linked by ethernet cabling, or later, wirelessly connected. Each computer had its own physical hard drive, and the hard drives of the computers were often represented by different drive letters on the workstation’s operating system interface and different kinds of software applications. A user could go onto a physical computer with its own drive, pull from the computer’s drive, or log onto network software to access the drive of a different computer in a different part of a room or building.

Internet usage has been correlated to users' loneliness. [129] Lonely people tend to use the Internet as an outlet for their feelings and to share their stories with others, such as in the " I am lonely will anyone speak to me" thread. Giffgaff has been around for almost 10 years now and has firmly established itself in the mobile network market as a low-cost, no-frills network. A subnetwork or subnet is a logical subdivision of an IP network. [81] :1,16 The practice of dividing a network into two or more networks is called subnetting.

A computer network comprises two or more computers that are connected—either by cables (wired) or WiFi (wireless)—with the purpose of transmitting, exchanging, or sharing data and resources. You build a computer network using hardware (e.g., routers, switches, access points, and cables) and software (e.g., operating systems or business applications). Kessler, Sarah (11 October 2010).

IPv6 is not directly interoperable by design with IPv4. In essence, it establishes a parallel version of the Internet not directly accessible with IPv4 software. Thus, translation facilities must exist for internetworking or nodes must have duplicate networking software for both networks. Essentially all modern computer operating systems support both versions of the Internet Protocol. Network infrastructure, however, has been lagging in this development. Aside from the complex array of physical connections that make up its infrastructure, the Internet is facilitated by bi- or multi-lateral commercial contracts, e.g., peering agreements, and by technical specifications or protocols that describe the exchange of data over the network. Indeed, the Internet is defined by its interconnections and routing policies. Carole Hughes; Boston College. "The Relationship Between Internet Use and Loneliness Among College Students".

[14] Today, the term Internet most commonly refers to the global system of interconnected computer networks, though it may also refer to any group of smaller networks.
