TELECOMMUNICATIONS, THE INTERNET, AND WIRELESS TECHNOLOGY

Telecommunications, the Internet, and Wireless Technology

are all related to the transmission of data and communication between individuals, devices, and organizations over long distances.

Telecommunications

refers to the exchange of information over long distances through a variety of channels, such as telephone lines, cables, and satellite links.

Telecommunications

can include both voice and data communications, and it encompasses a wide range of technologies and services, including traditional telephony, fax, email, and video conferencing.

Telegraph

The first major telecommunications technology was the telegraph, which was invented in the early 19th century.

Telegraph

It allowed people to send messages over long distances using a system of electrical wires and a code of dots and dashes called Morse code.

Morse Code

a code of dots and dashes

Alexander Graham Bell

Who invented the Telephone?

Telephone

•In 1876, Alexander Graham Bell invented the telephone, which allowed people to communicate with each other using their voices instead of Morse code. The telephone quickly transformed the way people communicated.

Radio

In the early 20th century, this technology was developed, which allowed people to transmit and receive audio signals wirelessly over long distances. This led to the development of the broadcast industry and the widespread adoption of radio as a medium for entertainment, news, and information.

Television

In the mid-20th century, this technology was developed, which allowed people to transmit and receive audio and video signals wirelessly over long distances. This led to the development of the television industry and the widespread adoption of television as a medium for entertainment, news, and information.

Satellite communications

In the 1960s, the first telecommunications that were launched into space, which allowed people to communicate over long distances without the need for wires or cables.

Satellite communications

•This technology revolutionized the telecommunications industry and made global communication much easier and more efficient.

Digital communications

In the late 20th century, this telecommunications technology was developed, which allowed people to transmit and receive data over long distances using digital signals instead of analog signals.

Digital communications

This technology enabled the development of the internet and other digital communication technologies, such as email and instant messaging.

Mobile communications

In the 21st century, this telecommunications technology has become dominant, allowing people to communicate wirelessly using mobile phones and other portable devices. This technology has transformed the way people communicate and has enabled new forms of social interaction and commerce

The Internet

is a global network of interconnected computer networks that enables the exchange of information and communication between individuals, organizations, and devices worldwide.

The Internet

It is a decentralized system that uses standard communication protocols to connect millions of devices, servers, and networks to each other.

ARPANET

The precursor to the internet was this, a project funded by the US Department of Defense in the 1960s.

ARPANET

It was designed to enable communication between researchers in different locations.

TCP/IP (Transmission Control Protocol/Internet Protocol)

This was developed in the 1970s as a way of ensuring that data could be transmitted reliably across different networks.

Domain Name System (DNS)

This was developed in the 1980s to provide a system for naming and addressing resources on the internet, making it easier for users to navigate and access information.

Tim Berners-Lee

Who proposed the World Wide Web?

World Wide Web

In 1989, Tim Berners-Lee proposed this, a system for sharing information through hypertext documents that could be accessed via the internet. The first website went live in 1991.

Browser Wars

•In the mid-1990s, this began, with Microsoft's Internet Explorer and Netscape Navigator battling for dominance in the market.

Search Engines

In the late 1990s, this is ike Google, Yahoo!, and AltaVista emerged as a way to help users find the information they needed more easily.

Web 2.0

In the early 2000s, this was coined to describe a shift towards more interactive and user-driven web applications, such as social media, blogs, and wikis.

Mobile Internet

With the advent of smartphones and mobile devices, the internet became increasingly accessible on-the-go. This usage surpassed desktop usage in 2016.

Internet of Things (IoT)

This refers to the proliferation of connected devices, such as smart homes, wearable technology, and autonomous vehicles, which are capable of communicating with each other over the internet.

Blockchain

emerged in 2008 with the launch of Bitcoin, and has since become the basis for a wide range of decentralized applications, including cryptocurrencies, smart contracts, and digital identity management.

Wireless Technology

refers to the use of radio waves, microwaves, and other electromagnetic waves to transmit data and information without physical cables or wires.

Wireless Technology

can include everything from cellular networks to Wi-Fi to Bluetooth, and it has revolutionized the way we communicate and access information.

Wireless Technology

refer to the methods and protocols used to transmit and receive data over a wireless network.

Common Wireless Technologies

Wi-Fi
Bluetooth
NFC
Zigbee
