An extended access control list (ACL) is a set of rules that filters network traffic based on source and destination IP addresses, protocol type, and port numbers, providing more granular control than a standard ACL.
Term 274
Extended File Allocation Table (exFAT) is a file system created by Microsoft that allows very large files and large storage volumes to be used across different operating systems like Windows and macOS.
Term 275
The Extended File System (ext) is a foundational file system family used in Linux operating systems to organize and manage data on storage devices.
Term 276
An Extended Service Set Identifier (ESSID) is the name of a wireless network that uses multiple access points to cover a larger area, allowing devices to roam seamlessly between them.
Term 277
Extensible Authentication Protocol (EAP) is a flexible authentication framework used in network access control, particularly in wireless and point-to-point connections, that supports multiple authentication methods without requiring changes to the underlying protocol.
Term 278
EAP over LAN (EAPoL) is a protocol that carries authentication messages between a device and a network access point before the device is allowed to connect to the network.
Term 279

Term 280
External Serial Advanced Technology Attachment is a standard interface for connecting external storage devices like hard drives and SSDs to a computer using a high-speed serial cable.
Term 281
Fail2ban is a security tool that monitors log files for repeated authentication failures and temporarily bans the offending IP addresses using firewall rules.
Term 282
Failover is the automatic switching to a backup system when the primary system fails, ensuring continuous operation and minimal downtime.
Term 283
Failover routing is a network design that automatically redirects traffic to a backup path when the primary path fails, keeping services available.
Term 284
Fault tolerance is the ability of a system to continue operating properly even when one or more of its components fail.
Term 285
Fibre Channel (FC) is a high-speed network technology primarily used for storage area networks (SANs) to connect servers to shared storage devices.
Term 286
A backup route in an EIGRP network that is immediately available if the primary route fails, without needing to run the Diffusing Update Algorithm (DUAL) again.
Term 287
First Hop Redundancy Protocol (FHRP) is a network protocol that provides automatic default gateway failover for hosts on a subnet.
Term 288
Fiber internet is a broadband connection that uses strands of glass or plastic to transmit data as pulses of light, offering higher speeds and more reliable service than traditional copper-based connections.
Term 289
A fiber optic cable is a high-speed data transmission medium that uses pulses of light traveling through thin strands of glass or plastic to carry information over long distances with minimal signal loss.
Term 290
Fibre Channel is a high-speed networking technology used to connect computer data storage to servers, enabling fast and reliable data transfer in enterprise data centers.
Term 291

Term 293
Google Cloud Filestore is a managed file storage service that lets you mount a network file system (NFS) to multiple virtual machines simultaneously, just like a shared folder on an office network.
Term 294
A firewall is a network security system that monitors and controls incoming and outgoing traffic based on predetermined security rules to protect trusted internal networks from untrusted external networks.
Term 295
A firewall rule is a set of conditions that tells a firewall which network traffic to allow or block based on attributes like source, destination, port, and protocol.
Term 296
firewalld is a dynamic firewall management tool for Linux systems that controls incoming and outgoing network traffic using zones and rules.
Term 297
Firmware is specialized software permanently stored in read-only memory on a hardware device that controls how that device operates at a basic level.
Term 298
A firmware update is a process that replaces or patches the permanent software programmed into a hardware device to fix bugs, patch security vulnerabilities, or add new features.
Term 299
A First Hop Redundancy Protocol provides automatic backup for the default gateway router on a network so that devices keep working if the primary router fails.
Term 300
The first IP address in a subnet that can be assigned to a host, typically one higher than the network ID.
