Understand how two or more computers and devices form a network, using data, software, and printers, with nodes following network protocols to share resources.
Design, install, and troubleshoot computer networks while maintaining switches, firewalls, and servers, provision internet access, and configure DNS and DHCP for reliable, secure end-user connectivity.
Computer networks enable resource sharing and communication across devices and users. They power email, online newspapers, blogs, websites, and services over the internet, plus client-server apps and video conferencing.
Identify the devices that create a computer network, including clients, workstations, servers, hubs, switches, routers, access points, firewalls, intrusion prevention systems, media, and MPLS WAN concepts.
Common network application software includes web browsers, email clients, instant messaging, and collaboration apps, with examples such as Mozilla Firefox, Google Chrome, Microsoft Edge, Thunderbird, Outlook, WhatsApp, and WebEx.
Compare local area networks and wide area networks, explaining private LANs for small offices and campuses, broadcast domains, ISP connectivity, VPN/MPLS options, bandwidth, reliability, and cost.
Compare campus area networks (CAN) and metropolitan area networks (MAN), showing how CAN interconnects local area networks across a campus and how MAN spans a metropolitan region.
RFCs, or requests for comment, are IETF technical documents that develop and standardize network protocols, serving as the building blocks for cross-platform internet communication.
Explore ad hoc wireless topology where devices connect and communicate without an access point, forming a small peer-to-peer wireless network that relies on the wireless channel.
Explore star topology, where every workstation connects to a central switch, enabling easy installation and minimal disruption, while noting potential central device failure and higher setup costs.
Explore the dual ring topology, which uses a primary and secondary ring to provide redundancy, stability, and additional data paths, enhancing network reliability.
Explore the basic tenets of the internet and how they work, and plan your next steps by accessing free webinars, training accounts, and cybersecurity insights.
