Key Term Knowledge Base: Key Terms Related to CompTIA Network+

The CompTIA Network+ certification is an essential credential for professionals in the field of IT networking, signifying a foundational understanding of networking concepts, infrastructure, operations, security, and troubleshooting. Knowing the key terms associated with CompTIA Network+ is vital for individuals pursuing a career in networking, as it ensures they have the necessary vocabulary to understand study materials, pass the certification exam, and communicate effectively in the workplace. Below is a list of key terms and definitions that are fundamental to the CompTIA Network+ certification.

NetworkingThe practice of connecting computers and other devices together to share resources such as files, printers, and Internet access.
OSI ModelA conceptual framework used to understand network interactions in seven layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application.
TCP/IPA set of protocols governing the Internet, including TCP (Transmission Control Protocol) and IP (Internet Protocol), which dictate how data is transmitted across networks.
SubnettingThe process of dividing a network into smaller, manageable parts called subnets to improve performance and security.
VLAN (Virtual LAN)A method to create distinct broadcast domains in a LAN by segmenting a network into smaller networks, improving management and security.
FirewallA security device or software used to control the flow of network traffic between networks or devices, offering protection by blocking unauthorized access while permitting authorized communications.
VPN (Virtual Private Network)A technology that creates a safe and encrypted connection over a less secure network, such as the internet, allowing secure communication between networks or users in different locations.
DHCP (Dynamic Host Configuration Protocol)A network management protocol used to automate the process of configuring devices on IP networks, allowing them to use network services such as DNS, NTP, and any communication protocol based on UDP or TCP.
NAT (Network Address Translation)A method of remapping one IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.
WLAN (Wireless LAN)A local area network that uses radio waves to connect devices such as computers and mobile devices to the Internet and to each other without the use of wires.
QoS (Quality of Service)The description or measurement of the overall performance of a service, such as a telephony or computer network or a cloud computing service, particularly the performance seen by the users of the network.
IPv4The fourth version of the Internet Protocol, which uses a 32-bit address scheme allowing for a total of approximately 4.3 billion addresses.
IPv6The most recent version of the Internet Protocol, designed to replace IPv4, using a 128-bit address space to support a virtually unlimited number of unique IP addresses.
DNS (Domain Name System)The hierarchical and decentralized naming system used to identify computers, services, and other resources reachable through the Internet or other IP networks by translating human-readable names to IP addresses.
SwitchA networking device that connects devices together on a computer network, using packet switching to receive, process, and forward data to the destination device.
RouterA networking device that forwards data packets between computer networks, performing traffic directing functions on the Internet.
WAN (Wide Area Network)A telecommunications network that extends over a large geographic area for the primary purpose of computer networking. Wide area networks are often established with leased telecommunication circuits.
LAN (Local Area Network)A network that connects computers and devices in a limited geographical area such as a home, school, computer laboratory, or office building.
ProtocolA set of rules or procedures for transmitting data between electronic devices, such as computers. In networking, protocols include TCP/IP, HTTP, SMTP, and FTP.
BandwidthThe maximum rate of data transfer across a given path or connection in a network, usually measured in bits per second (bps).

This list represents the foundational knowledge required to understand and work within the domain of networking, particularly for those aiming to achieve the CompTIA Network+ certification.
