- Understand how multiple networks are used in everyday life.
- Define how topologies and devices are connected in a small to medium-sized business network.
- Understand the basic characteristics of a network that supports communication in a small to medium-sized business.
- Describe trends in networking that will affect the use of networks in small to medium-sized businesses.
Today’s computing and smart devices are expected to be always-connected devices to support the way we learn, communicate, do business, work, and play, in any place, on any devices, and at any time. In this chapter, we review the history of networking, how the Internet works, and the use of multiple networks in organizations today.
- 5.1: Introduction to Networking and Communication
- The way we communicate has affected every important aspect of our lives and the world on a broad scale. Education, business, politics, etc.. are all heavily dependent on the internet to communicate effectively.
- 5.2: A Brief History of the Internet
- This chapter presents a brief history of the Internet and the stage of information systems upon which our social and commerce connections progressively depend.
- 5.3: Networking Today
- The evolution of the world we live i has been drastically impacted by the internet. most of us cannot imagine living without social media, texting, online shopping, etc.. in this chapter, we discuss networking today.
- 5.4: How has the Human Network Influenced you?
- Online Communication has changed our lives, and one important aspect is education. Online learning has altered the education system to affect students' learning by providing students more opportunities and not limiting them to local institutions to receive an education.
- 5.5: Providing Resources in a Network
- Networks connect various devices in our homes, offices, schools, etc. Many devices could be simultaneously connected to the same network, such as a printer, a laptop, a smartphone, and an iPad.
- 5.6: LANs, WANs, and the Internet
- Devices and media are the hardware of the network. The messages being sent and received from one device to another are the software, and LANs and WANs connect the two devices to facilitate sending the message from the sender to the recipient.
- 5.7: Network Representations
- Abbreviations apply to networks as well as people's names, school names, etc. Network representations are symbols utilized to represent the different hardware and connections that make up a network.
- 5.8: The Internet, Intranets, and Extranets
- The internet is made up of many interconnected networks. LANs are connected to each other through a WAN.
- 5.9: Internet Connections
- There are various ways in which one can connect to the internet. A connection to the internet could be through dial-up, cable, satellite, cellular, and DSL.
- 5.10: The Network as a Platform Converged Networks
- There are different types of networks, converging networks, and separate networks. Separate networks do not allow different devices connected to different networks to communicate because they aren't interconnected. However, converged networks are built to convey data among various devices connected to the same network.
- 5.11: Reliable Network
- Networks aid various applications and services when it comes to the physical infrastructure of the service or application. Underlying network architecture needs to deliver the four fundamental qualities, which are, Quality of Service (QoS), security, fault tolerance, and scalability.
- 5.12: The Changing Network Environment Network Trends
- Technology is constantly evolving, and new network trends influence organizations and consumers.
- 5.13: Technology Trends in the Home
- Networking trends in the home provide more convenient and user-friendly services, such as smart home technology, which interconnects different devices for habitual appliances.
- 5.14: Network Security
- Like any other aspect in life, everything has its cons, and the cons of the internet are ensuring network safety and security. Ensuring a network is secure requires technologies, protocols, devices, tools, and techniques that keep data secure and moderate threat vectors.
