Term 601
A Straight Tip Connector, often called an ST connector, is a fiber optic cable connector that uses a twist-on bayonet-style coupling mechanism to securely attach a fiber optic cable to a device or patch panel.
Term 602
A straight-through cable is a type of Ethernet cable where the wire arrangement is identical on both ends, used to connect different types of network devices, like a computer to a switch.
Term 603
Stream Control Transmission Protocol (SCTP) is a transport layer protocol that combines the reliability of TCP with the speed of UDP and adds the ability to send multiple independent streams of data over a single connection.
Term 604
A subinterface is a virtual interface created on a single physical network interface to allow it to carry multiple VLANs or logical networks separately.
Term 605
A subnet is a logical subdivision of an IP network, created by partitioning a larger network address space using subnet masks.
Term 606
A subnet mask is a 32-bit number that helps a computer or network device determine which part of an IP address identifies the network and which part identifies the host device on that network.
Term 607
Subnetting is the process of dividing a larger IP network into smaller, more manageable subnetworks (subnets) to improve performance, security, and efficient use of IP addresses.
Term 608
A Subscriber Connector (SC) is a fiber optic cable connector known for its push-pull coupling mechanism and square shape, commonly used in data centers and telecommunications for single-mode and multimode fiber connections.
Term 609
In EIGRP, a successor is the primary next-hop router chosen to forward packets to a destination network, determined by having the highest feasibility and lowest metric.
Term 610
A Switch Virtual Interface (SVI) is a logical, software-based interface on a multilayer switch that provides Layer 3 routing capabilities for a VLAN, allowing devices in different VLANs to communicate without an external router.
Term 611
A switch is a networking device that connects devices on a local area network and uses MAC addresses to forward data only to the intended recipient.
Term 612
A logical interface on a network switch that allows it to be managed and communicate with other devices using IP addresses.
Term 613
A Switched Port Analyzer (SPAN) is a feature on network switches that copies traffic from one or more ports to a monitoring port for analysis.
Term 614
A virtual interface on a Layer 3 switch that allows that switch to route traffic between VLANs without needing a separate router.
Term 615
A switchport is a physical or virtual interface on a network switch that connects devices like computers, printers, or other switches to a local area network.
Term 616
Symmetric encryption is a cryptographic method where the same secret key is used to both encrypt and decrypt data, ensuring confidentiality between two parties.
Term 617
Syslog is a standard protocol used to send and store log messages from network devices and servers to a central logging server for monitoring and troubleshooting.
Term 618
System Restore is a Windows utility that lets you revert your computer's system files, registry settings, and installed programs to a previous state without affecting your personal files.
Term 619
TACACS+ is a protocol that separates authentication, authorization, and accounting functions to control who can access network devices and what they can do.
Term 620
TCP (Transmission Control Protocol) is a core internet protocol that ensures data is sent reliably and in order between devices over a network.
Term 621
TCP is a connection-oriented transport layer protocol that ensures reliable, ordered, and error-checked delivery of data between applications over IP networks.
Term 622
A TCP Proxy Load Balancer is a network device that terminates incoming TCP connections from clients, establishes a new TCP connection to a backend server, and relays data between the two, enabling advanced traffic management and security features.
Term 623
The TCP/IP model is the set of communication protocols used to connect devices on the internet and most private networks, organizing network communication into four layers.
Term 624
Telnet is a network protocol that provides a bidirectional, interactive text-based communication session between two machines over a network, typically used for remote access and management of network devices.
Term 625
TKIP is a security protocol used in Wi-Fi networks to strengthen encryption by dynamically changing the encryption key for each data packet.
Term 626
A user profile that Windows creates automatically when the regular profile fails to load, providing limited and temporary access to the system.
Term 627
TACACS+ is a network security protocol that separates authentication, authorization, and accounting to control who can access network devices and what they can do.
Term 628
A DNS Text Record (TXT record) is a type of resource record that stores human-readable or machine-readable text data associated with a domain name.
Term 629
TFTP, or Trivial File Transfer Protocol, is a simple, lightweight network protocol used to transfer files between devices without the security or advanced features of FTP.
Term 630
Throughput is the rate at which data is successfully transferred from one point to another over a network, typically measured in bits per second.
