The Effects of Technology on Communication

Technology is continually developing a system of information processing aimed at providing better ways of living. Technological infrastructures range from small chipsets up to the satellites orbiting the planet.

Technology

Computer science is focused on the development of hardware and software programs that improve data processing, networking, communications and related computing tasks. Many developing nations are still in the process of adapting to these new technologies.

History

Our first telephone systems established communication connections via circuit-switched networks that allowed communication between two physically connected (i.e., cable wire) phone lines. Then integrated circuits and transistors came into the picture. They used the same relay principle to create physical connections. This is the same network used by dial-up Internet services, which need a dedicated phone line to establish a dial-up network.

Digital Networks

Modern telephone systems use digital networks that don't rely on physical line connectivity between two callers. Instead, they use fiber optics to carry and transmit the digital connection, and can handle thousands of calls simultaneously. Along with this development, the Asymmetric Digital Subscriber Line (ADSL) network was established. ADSL provides faster Internet connectivity, and allows use of the phone and Internet at the same time.

Packet Switch Network

The latest development in communication is a cheaper and faster network using packet switching. This is called Voice Over Internet Protocol (VOIP). Instead of cable or fiber optics, it uses "packets," or small bits of data transmitted on the Internet.
Around the same time, Wireless Fidelity, or WiFi, networks were established. WiFi describes an Internet connection setup that allows handheld users to connect quickly using radio signals, and to move comfortably without using any cable wires. Wireless Application Protocol, likewise, is a current technology that enables access for handheld devices programmed with advance networking hardware and software.

Personal Digital Assistant

A personal digital assistant is a handheld computer device designed for users who need small but flexible electronic utilities. It is often called a "personal diary" because it allows fast organization and manipulation of information for a reasonably limited storage size.

E-learning

Electronic learning is an educational system that can be accessed anywhere via the Internet. This development contributes to better communication because it teaches us to adapt and utilize the latest technologies. We have learned to reach out and interact by using online tools such as software phones, instant messaging and blogging.
