The Linux-Mobile-Guide is a guide for users of Linux and computers phones, laptops, PDAs and other mobile computers. The Linux-Mobile-Guide is a guide for users of Linux and laptops, notebooks, PDAs and other mobile computers.This guide was former known as Linux-Laptop-HOWTO, but is now extended to Linux and mobile computing devices in general (laptops, PDAs, mobile phones, digital cameras, calculators, wearables, ...). These devices are different from desktop / tower computers.They use certain hardware such as PCMCIA cards, infrared ports and Bluetooth, batteries, docking stations. Equipment parts can not be changed as easily as in an office, for example, the graphics card. Often their hardware is more limited (disk space, processor speed). Hardware support for Linux (and other operating systems) on mobile devices is sometimes more limited (eg graphics chips, internal modems). They often use specialized hardware, hence finding a driver may be more difficult. Many times they are used in changing environments, so there is a need for multiple configurations and additional security strategies.The Linux-Mobile-Guide explains the installation methods for laptops and PDAs and the configurations for different ( network) environments, security issues for laptops and much more.
