Pervasive computing can help us control information quickly, efficiently, and effortlessly.
Pervasive Computing is about making our lives simpler.
Pervasive computing aims to activate people to accomplish a growing number of personal and
professional transactions using a new class of smart and portable devices. It provides people
easy access to corresponding information placed on powerful networks, permitting them to
simply take action anywhere, round the clock.
These new clever appliances or “smart devices” are embedded with microprocessors that permit
users to plug into intelligent networks and gain direct, simple, and secure access to both
corresponding information and services. These devices are as simple to utilize as calculators,
telephones or kitchen toasters.
Pervasive computing eases life by uniting open standards-based applications with day-to-day
activities. It eliminates the complexity of new technologies, helps us to be more efficient in our
work and gives us more free time. Pervasive computing drives out the notion of working as an
isolated activity, which is bound to desktop, and instead makes it an integral part of day-to-day
life.

Did u know? What is the aim of Pervasive Computing?
Pervasive computing aims to speed up progress in every field of computing, by uniting
together researchers, educators and practitioners from discrete disciplines. The aim is to
attain a world saturated with computing and communication, yet gracefully linked with
human users.
1.1 What is WAP?

An important landmark in the world of communications came with the introduction of WAP for
accessing the universal Internet-based information by means of wireless devices.

Wireless Application Protocol (WAP) is an application environment and group of communication
protocols for wireless devices modeled to activate manufacturer-vendor and technology-
independent access to the Internet and advanced telephony services.

Notes The Wireless Application Protocol (WAP) is an open, global specification that
empowers mobile users with wireless devices to easily access and interact with information
and services instantly.

1.1.1 Importance and Benefits of WAP

WAP fills the void between the mobile world and the Internet as well as corporate intranets and
provide the ability to present a wide range of mobile value-added services to subscriber-
independent of their network, bearer and terminal. Mobile subscribers can access the same
information from a pocketsize device as they can use with the desktop.
