Study Notes
Data Communications
- Data communications is the process of transferring data from one place to another using computing and communication technologies.
- It involves the exchange of data between devices, systems, or networks.
Computer Network
- A computer network is a group of two or more computers connected to communicate data electronically.
- It enables data communication, resource sharing, and collaboration between devices.
Internet
- The internet is a global network of interconnected computers, networks, and devices.
- It uses guided, wireless, and fiber-optic technologies to connect private, public, business, academic, and government networks.
Evolution of the Internet
- The idea of ARPANET was proposed in 1961 by Leonard Kleinrock.
- The term "packet" was coined in 1965 by Donald Davies to describe data sent between computers over a network.
- ARPANET was the first computer network to use packet switching in 1969.
- The first email was sent in 1971 by Ray Tomlinson.
- Ethernet was developed in 1973 by Robert Metcalfe.
- The Internet Protocol (IP) was invented in 1978 by Bob Kahn and Vint Cerf.
- IPv4 was officially defined in 1981, and IPv6 was introduced in 1996.
Internetworking
- Internetworking is the process of connecting different networks using intermediary devices such as routers or gateways.
- It enables data communication among networks owned and operated by different entities using a common protocol.
Features of the Internet
- The internet uses TCP/IP protocol suite and IP as its addressing protocol.
- It is widely deployed on World Wide Web services using HTML linked pages and accessible by client software known as Web Browsers.
- It uses very high-speed backbone of fiber optics, including submarine communication cables.
Innovations in Computer Networking
- Cloud Computing is the practice of using a network of remote servers hosted on the Internet to store, manage, and process data.
- Internet of Things (IoT) has evolved from the convergence of wireless technologies, microelectromechanical systems (MEMS), micro-services, and the internet.
- Li-Fi Technology is a mobile wireless technology that uses light rather than radio frequencies to transmit data.
