IT Terms

Application Programming Interface (API)

A set of software routines that allows one software system to work with another. It defines the set of rules and protocols that enable the interaction and exchange of data between software components

Remote Procedure Call (RPC)

A communication protocol that allows a program to execute a procedure or function in a different address space.

Simple Network Management Protocol (SNMP)

A network protocol used for monitoring and managing devices on a network

Protocol Analyzer

Hardware or software that captures packets to decode and analyze their contents.

Message Queue Interface

Allows for asynchronous communication between applications through message queues

Communication Infrastructure Interface

Interface between the application platform and the communication infrastructure

Service Delivery Objective

level of service to be reached during alternate process mode (directly related to business needs)

Client

A device or software that requests services or resources from a server

Server

a computer or computer program that manages access to a centralized resource or service in a network.

Media

Medium of data transfer

Modem (Modulator-Demodulator)

Device that converts a digital bit stream into an analog signal (modulation) and converts incoming analog signals back into digital signals (demodulation).

Hub

A networking device that acts as a central connection point for multiple devices within one local area network (LAN)

Network Interface Card (NIC)

a hardware component that enables computers to communicate over a network

Switch

A hardware device that receives and forwards data packets directly to their intended destination device using MAC addresses within a LAN network

Router

a device that forwards data packets between computer networks using IP addresses.

Repeater

a device that picks up signals from lower-power radio units, such as mobile and portable radios, and retransmits them at a higher power. It allows low-power radio signals to be transmitted over longer distances.

Long Haul Network Diversity

diverse, long distance network utilizing different packet switching circuits among major long distance carriers - ensures long distance access should any carrier experience a network failure

Last-mile circuit protection

redundant combo of local carrier, microwave, and/or coaxial cable access to local communications loop - enables facility to have access during local carrier communication disaster (alternate local routing also utilized)

Alternate Routing

The use of alternate medium/media (copper, fiber optic cables) between networks, circuits or end points if normal network is

Diverse Routing

A method of providing telecommunication continuity which involve routing traffic through split or duplicate cable facilities

Terrestrial Media

Media is located in the ground or basement

Redundant Array of Physical Disk (RAID)

is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement or both

Homomorphic Encryption

A powerful encryption method that allows mathematical operations on encrypted data without decryption

Domain Name System Security Extensions (DNSSEC)

A cryptographic approach designed to enhance the security of the Domain Name System (DNS)

Regression

A machine learning technique used for predicting continuous numerical values based on input variables.

Clustering

a machine learning technique used for identifying patterns and relationships in unlabeled data. This group similar data points together based on their inherent similarities or distance metrics.

Naive Bayes

A machine learning technique commonly used for classification tasks based on probabilistic principles
