Recent advances in
portable and wireless technology have led to mobile computing, a new dimension in data communication and
processing.
·
Portable
computing devices coupled with wireless communications allow clients to access
data from virtually anywhere and at any time.
·
This
feature is especially useful to geographically dispersed organizations.
·
Some of the
software problems, which may involve data management, transaction management,
and database recovery—have their origins in distributed database systems.
Explanation:
·
It is a
distributed architecture where a number of computers, generally referred to as Fixed
Hosts (FS) and Base Stations (BS), are interconnected through a
high-speed wired network.
·
Fixed hosts
are general purpose computers that are not typically equipped to manage mobile
units but can be configured to do so.
·
Base
stations are Mobile Units' (MU) gateways to the fixed network. They are
equipped with wireless interfaces and offer network access services of which
mobile units are clients.
