Study Notes
Internet of Everything (IoE)
- IoE brings together people, data, process, and things to make networked connections more relevant and valuable.
- IoE enables new capabilities, richer experiences, and unprecedented economic opportunities for businesses, individuals, and countries.
Key Components of IoE
- People: Connecting people in more relevant, valuable ways.
- Data: Converting data into intelligence to make better decisions.
- Process: Delivering the right information to the right person (or machine) at the right time.
- Things: Physical devices and objects connected to the Internet and each other for intelligent decision making (also known as Internet of Things (IoT)).
Network Components
- Network infrastructure consists of three broad categories of network components: devices, media, and services.
- Network devices: intermediary devices, end devices, and network media.
Open Systems Interconnection Model (OSI)
- The OSI model groups communication functions into seven logical layers.
Human Networks
- A network consists of two or more entities, or objects, sharing resources and information.
- Examples of human networks: peer network, family network, and restaurant network.
Computer Networks
- A computer network consists of two or more computing devices connected to share resources and information.
- Computer networks can be classified by their geography: Local Area Network (LAN), Metropolitan Area Network (MAN), and Wide Area Network (WAN).
Importance of Networks in Our Lives
- Networks support the way we learn, communicate, work, and play.
Internet
- The internet is a service that interconnects all smart communication devices with a valid address.
- The internet is a worldwide interconnection of devices.
Network Devices
- Hub: operates at Layer 1, receiving and sending data.
- Switch: operates at Layers 1 and 2, receiving data, checking MAC addresses, and sending data.
- Router: operates at Layers 1, 2, and 3, receiving data, checking MAC addresses, checking IP addresses, and sending data.
Server
- A web server is a computer that stores web server software and a website's component files.
- A mail server is a computer that can handle and deliver e-mails over a network.
