Networking

A computer network is a set of devices connected through links. A node can be a computer, printer, or any other device capable of sending or receiving the data. The links connecting the nodes are known as communication channels.

OSI Model

The Open Systems Interconnection (OSI) model describes seven layers that computer systems use to communicate over a network.

IP (address, masks, type of networks, etc.)

IP address is the host identification number used for proper communication between devices. The IP address is a number assigned to a network interface, a group of interfaces (broadcast, multicast addresses) or to the entire computer network, used to identify network components and being one of the elements enabling them to communicate.

Knowledge of common protocols (DHCP, DNS, SSH, TCP/UDP, NTP, LDAP)

Network protocols are a set of rules, conventions, and data structures that dictate how devices exchange data across networks. In other words, network protocols can be equated to languages that two devices must understand for seamless communication of information, regardless of their infrastructure and design disparities.

VLAN

Short for virtual local area network, VLAN allows a network administrator to set up separate networks by configuring a network device, such as a router, without adjusting cabling. A VLAN allows a network to be divided, set up, and changed by a network administrator to organize and filter data accordingly.

Heading

HeadingHeading

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content.

Static and dynamic content editing

A rich text element can be used with static or dynamic content. For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Voila!

How to customize formatting for each rich text

Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.
