Mobile Computing with Linux
Mobile computing is mostly associated with laptops, PDAs, and cellular phones and
the data exchange between them. Mobile hardware components, such as external hard
disks, flash drives, or digital cameras, can be connected to laptops or desktop systems.
A number of software components are involved in mobile computing scenarios and
some applications are tailor-made for mobile use.
25.1 Laptops
The hardware of laptops differs from that of a normal desktop system. This is because
criteria like exchangeability, occupied space, and power consumption are relevant
properties. The manufacturers of mobile hardware have developed the PCMCIA (Per-
sonal Computer Memory Card International Association) standard. This standard covers
memory cards, network interface cards, ISDN and modem cards, and external hard
disks. How the support for such hardware is implemented in Linux, what needs to be
taken into account during configuration, what software is available for the control of
PCMCIA, and how to troubleshoot any possible problems is described in
Chapter 26,
PCMCIA
