Configuration drift is the gradual, unplanned change in a system's configuration settings over time, causing it to deviate from its original or desired state.
Term 154
A Configuration Management Database (CMDB) is a centralized repository that stores information about all the hardware, software, and other components in an IT system and their relationships.

Term 156
Consumption-based pricing is a cloud billing model where you pay only for the resources you actually use, rather than paying a fixed upfront fee.
Term 157
A container is a lightweight, standalone software package that includes everything needed to run an application, such as code, runtime, system tools, and libraries.
Term 158
Container scanning is the automated process of inspecting container images for known security vulnerabilities, misconfigurations, and compliance issues before they are deployed.
Term 159
Content-addressable Memory (CAM) is a special type of computer memory used in high-speed networking devices that searches its entire contents in a single clock cycle to find a matching value, rather than searching one address at a time.
Term 160
A controller is a hardware chip or software program that manages data flow and communication between a computer's operating system and its connected devices or networks.
Term 161
A cooling fan is a hardware component that moves air across heat-generating parts to prevent overheating and maintain safe operating temperatures.
Term 162
Copper cable is a type of network cabling that uses copper wires to transmit data using electrical signals.
Term 163
A corrupted profile is a user account on a computer that has become damaged or dysfunctional, preventing the user from logging in or accessing their personal settings and files.
Term 164
CoS (Class of Service) is a method of marking Ethernet frames with a priority level to manage traffic and ensure higher-priority data gets through first.
Term 165
The Cost Optimization pillar is a set of design principles and best practices in cloud computing aimed at minimizing expenditure while maximizing the value delivered from cloud resources.
Term 166
The Central Processing Unit (CPU) is the main electronic brain of a computer that carries out instructions from software by performing basic arithmetic, logic, control, and input/output operations.
Term 167
CRC (Cyclic Redundancy Check) is an error-detecting code used to detect accidental changes to raw data in digital networks.
Term 168
A crimper is a handheld tool used to attach a connector, like an RJ45 plug, to the end of a network cable by compressing metal pins into the cable's wires to create a secure and conductive connection.
Term 169
A Certificate Revocation List (CRL) is a published list of digital certificates that have been revoked by a Certificate Authority before their scheduled expiration date.
Term 170
Cross-Region Replication is the automated copying of data from a storage bucket in one geographic region to a bucket in a different geographic region for disaster recovery, compliance, or lower latency access.
Term 171
A crossover cable is an Ethernet cable with reversed transmit and receive wire pairs, used to directly connect two similar devices without a switch or hub.
Term 172
Carrier Sense Multiple Access with Collision Detection is a network protocol used in Ethernet to manage data transmission and handle collisions when two devices send data at the same time.
Term 173
A Certificate Signing Request is a block of encoded data sent to a Certificate Authority to apply for a digital certificate.
Term 174
curl is a command-line tool that lets you transfer data to or from a server using various network protocols, commonly used to test APIs and download files.
Term 175
A Cyclic Redundancy Check (CRC) is an error-detecting code used to verify that data transmitted over a network or stored on a device has not been corrupted.
Term 176
DAS is a storage device directly connected to a computer without a network, offering fast local access.
Term 177
DAST (Dynamic Application Security Testing) is a security testing method that finds vulnerabilities in running web applications by simulating real attacks from the outside.
Term 178
A Data Center Interconnect is a network connection that links two or more separate data centers together so they can share data, resources, and services as if they were a single facility.
Term 179
Data classification is the process of organizing data into categories based on its sensitivity, value, and criticality to an organization, so that appropriate security controls can be applied.
Term 180
A Data VLAN is a virtual local area network configured on a switch to carry user-generated traffic, separating it from management, voice, or other types of network traffic.
