It is expendable, short-lived and heavily influenced by media, trends, marketing and so on. The same applies to smartphones, tablets and other devices nowadays.A server is designed for computer-to-computer interaction. A server has only one interface to the outside world that matters -- the network interface. A server is designed to be centrally manageable, robust and reliable under high load for years. sayble2000 https://padlet.com/llo17004875/j9l412irdx96/wish/243924820 2018-03-20 10:54:27 UTC https://padlet.com/llo17004875/j9l412irdx96/wish/243924820 Software and hardware sayble2000 https://padlet.com/llo17004875/j9l412irdx96/wish/243925830 On the Internet the dominant operating systems among servers are UNIX-like open source distributions, such as those based on Linux and FreeBSD, with Windows Server also having a very significant share. Proprietary operating systems such as z/OS and macOS Server are also deployed, but in much smaller numbers.

Since servers are usually accessed over a network, many run unattended without a computer monitor or input device, audio hardware and USB interfaces. Many servers do not have a graphical user interface (GUI). They are configured and managed remotely. ]]> 2018-03-20 10:57:16 UTC https://padlet.com/llo17004875/j9l412irdx96/wish/243925830 How a router is connected to a computer system: pat17003700 https://padlet.com/llo17004875/j9l412irdx96/wish/243925969
