Frequently Asked Questions – Best Network Communications Course
Network communication, or internetworking, defines a set of protocols (that is, rules and standards) that allow application programs to talk with each other without regard to the hardware and operating systems where they are run (Source: IBM).
Network Communications Professionals are responsible for the management of computer networks. They work with the physical computer networks within various companies and organizations. According to the U.S. Bureau of Labor Statistics, demand for Network Communications Professionals is expected to grow at least 5% between 2020-2030.
Network Management is operating, administering, monitoring, maintaining, and controlling a computer network.
A network engineer, also known as a network architect, maintains the connectivity of networks, including data, voice, calls, videos, and wireless network services. They work with a company’s computer network, using information technology to develop a network architecture and network systems for everyone in a company to use.
“These information networks can include local area networks (LANs), wide area networks (WANs), intranets, and extranets.” Network Engineers ensure all network systems are functioning properly and aim to provide the best possible infrastructure, security, and performance to the end users.

Computer networking involves connecting computing devices (such as laptops, desktops, servers, smartphones, and tablets) and IoT devices (such as cameras, door locks, doorbells, refrigerators, audio/visual systems, thermostats, and various sensors), which communicate with one another.
Computer Networking encompasses the network design, building, management, maintenance, and use of a network. It ensures computer communication and mobile communication.
Computer networking enables devices to be connected on:
1. A Local area network (LAN),
2. A Wide area network (WAN)- which might connect offices, data centers, cloud applications, and cloud storage of a business or organisation together
3. Or the internet.
