CCNA study plan that combines various resources like books, videos, and practical labs

The process of actively engaging with information from a book, such as taking notes, summarizing, and explaining concepts learned

Domain 2.0, focusing on providing access to a network, using technologies such as switches and VLANs

Domain 1.0, covering fundamental networking concepts, like network topology, transmission media, and network devices

Domain 3.0, involving routing protocols, subnetting, and addressing, enabling communication between networks

Domain 4.0, related to essential network services like DHCP, DNS, and NAT, supporting essential network functions

Domain 5.0, covering security principles like firewalls, access control, and encryption, ensuring network integrity

Domain 6.0, encompassing automation and programmability techniques, enabling efficient network management

Engaging with learning material by participating actively, like taking notes, summarizing, and explaining.

A method of studying that includes practical, hands-on exercises with the technology being learned. For the CCNA, this involves configuring Cisco routers and switches.

Software programs that realistically simulate network environments, allowing you to practice configuring and troubleshooting Cisco devices without needing real hardware.

Software programs that emulate network behavior, allowing for testing and configuration of network devices in a virtual environment.

Real Cisco routers and switches used for hands-on practice. While valuable, it can be expensive and impractical for most individuals.

Cisco Packet Tracer, a network simulation software commonly used for CCNA study. It offers a safe and cost-effective way to practice configuring Cisco equipment.

The process of combining different learning resources, like books, video courses, and labs, to enhance understanding and retention.

Studying a topic from multiple perspectives, using different learning resources like books, video courses, and practical labs.

A network is a collection of interconnected devices, allowing them to share resources and communicate with each other.

A Local Area Network (LAN) is a network confined to a small geographical area, typically a building or office, connecting devices like computers, printers, and servers.

A Wide Area Network (WAN) is a network that spans a large geographical area, connecting offices, cities, or even countries.

A client is a device on a network that requests resources or services from other devices.

A server is a device on a network that stores resources and provides services to other devices.

A switch is a networking device that connects devices on a network and intelligently forwards data only to the intended recipient.

A router is a networking device that connects multiple networks, allowing data to be transmitted between them.

A firewall is a security device that inspects network traffic and blocks any unauthorized or suspicious traffic, protecting the network from threats.

A group of interconnected devices within a limited area, like an office.

A network spanning a large geographical area, connecting cities or countries.

A device that connects to a network, such as a computer, smartphone, router, etc.

Anything shared over a network, like a webpage, file, or printer.

A device connecting devices in a LAN, usually with many ports for connections.

A device connecting LANs to external networks, like the Internet.

A device combining router, switch, wireless access point, and firewall functionalities.

A hardware appliance inspecting network traffic, allowing or denying it based on rules.

The most basic unit of information used by computers. It represents a binary digit, either 0 or 1.

A group of eight bits. It is used to represent a single character, such as a letter, number, or symbol.

A standard for wired network communication, defining how data is formatted and transmitted over network cables. It's like a set of rules everyone agrees on.

A standard for wireless network communication, allowing devices to connect to the internet without cables. It's like a set of rules everyone agrees on for wireless communication.

The language that computers use to store and process information. It uses only two digits: 0 and 1.

A governing body that sets standards for computer networks, including Ethernet and Wi-Fi. Think of them as the rule-makers for network communication.

For communication to occur between two parties, they must agree on the rules and the medium of communication. This applies to both humans and computers.

Computers communicate using binary code, where all information is represented by combinations of 0s and 1s. It's like a secret language that computers understand.

The process of adding a header to data to indicate its destination and purpose within the network.

The movement of data from one network device to the next on its path to the final destination. Each hop represents a step within the network.

A networking model that defines the functions needed for network communication and divides them into layers, each with specific tasks and protocols. This model helps us understand how networks work.

A networking model that influenced how we think about networks but is not used today. It has seven layers, each with specific roles in network communication.

The networking model used in modern networks, named after two key protocols: TCP and IP. It consists of four or five layers, each responsible for different tasks in network communication.

The layer in a networking model that defines the physical requirements for transmitting data, including ports, connectors, cables, and signal encoding.

The layer in a networking model that deals with hop-to-hop delivery of messages. It ensures error-free data transmission between network devices.

The interaction between different layers within the same device, where a higher layer relies on the services provided by the layer below it.
