Networking – Types, key equipment, and educational programs
Networking is the process of establishing connections between devices to facilitate communication and resource sharing. It involves the use of various hardware and software components to enable data transfer across the network, allowing individuals and organizations to access and exchange information efficiently. Today, networking has become an indispensable aspect of both personal and professional lives. Its ability to facilitate smooth communication and efficient data exchange has changed how people interact.
What is networking?
Networking is the practice of connecting computers to help them share data and resources. While originally established for defense and military use, today, networking has changed how people interact with loved ones, collaborate with colleagues, and engage with business partners. A key aspect of businesses, networking makes email, e-commerce, live streaming, video sharing, and social media, i.e., the internet itself, possible.
Types of network
Local area network (LAN): This is a network infrastructure that connects devices within a small geographical area, such as homes, offices, or schools.
Wide area network (WAN): A wide area network encompasses larger geographic regions, connecting multiple LANs over vast distances. The most prominent example of a WAN is the internet, a global network that enables communication and data exchange on a worldwide scale.
Wireless network: Wireless networks use radio waves or infrared signals to transmit data between devices without physical connections. Wi-Fi networks are key examples of wireless networking.
Metropolitan area network (MAN): This type covers a larger area than a LAN but smaller than a WAN. MANs are often used to connect multiple LANs within a city or metropolitan region.
Virtual private network (VPN): VPNs provide secure connections over public networks. They encrypt data, ensuring privacy and confidentiality for users.
Key equipment and accessories
To facilitate and optimize connection capabilities, components like ethernet cables, network adapters, network switches, wireless access points, network routers, and powerline adapters are required. Additionally, for a well-functioning network, the following equipment forms the foundation of reliable connections:
Servers: Servers store and manage data, applications, and resources that can be accessed by other devices on the network.
Modems: Modems connect networks to the internet by converting digital data into analog signals for transmission over telephone lines.
Hubs: Hubs connect multiple devices in a network, but they have largely been replaced by more efficient switches.
Network firewalls: Network firewalls protect networks from unauthorized access and potential threats, ensuring data security.
Network storage devices: Storage devices provide centralized data storage accessible to authorized users on the network.
Further, to enhance the convenience of setting up and using a wired network, one can get networking accessories like cable ties and clips to keep wires organized.
Education and training
If looking to pursue a career in networking, one can find various institutes offering specialized networking courses and certification programs. Here are a few options to consider
Cisco Certified Networking Associate (CCNA): A certification covering networking and security fundamentals, IP services, automation, and programmability
Certified Information Systems Security Professional (CISSP): A certification program covering technical skills and hands-on training in implementing and managing a security program
JNCIA (Juniper Networks Certified Internet Associate)-Junos: A program for networking professionals with beginner to intermediate knowledge
Certified Ethical Hacker (CEH): A course covering skills to identify and mitigate security threats
Microsoft Certified Azure Administrator Associate: A course covering maintenance of services related to computing, storage, network, and security
