About Linux Linux  is a free, open-source operating system kernel developed by finish software engineer named Linus Torvalds in 1991 as his  Linux has been under active development since 1991. It has evolved to be versatile and is used all over the world, from web servers to cellphones. However, newcomers to Linux may find it difficult to approach the structure of an unfamiliar operating system. This guide gently introduces key terminal skills and equips newcomers to learn more about Linux. The Terminal For most of the time you access a cloud server, you'll be doing it through a terminal shell. The shell allows you to execute commands on the droplet. All administrative tasks can be accomplished through the terminal. This includes file manipulation, package installation, and user management. The terminal is interactive.

Most of these users, however, have never heard of the ethical reasons for which we developed this system and bui...

Computer Computers and computing devices from different eras A  computer  is a device that can be instructed to carry out sequences of  arithmetic  or  logical  operations automatically via  computer programming . Modern computers have the ability to follow generalized sets of operations, called  programs .  These programs enable computers to perform an extremely wide range of tasks. Computers are used as  control systems  for a wide variety of  industrial  and  consumer devices . This includes simple special purpose devices like  microwave ovens  and  remote controls , factory devices such as  industrial robots  and  computer-aided design , and also general purpose devices like  personal computers  and  mobile devices  such as  smartphones . Early computers were only conceived as calculating devices. Since ancient times, simple manual devices like ...
