Isolated user-space process tree bounded by Linux namespaces and cgroups sharing the host kernel.

dockerkubernetesconceptbeginner

Immutable read-only tarball bundle containing root filesystem layers, binary dependencies, and OCI runtime metadata.

dockerkubernetesconceptbeginner

Linux kernel mechanism metering and limiting hardware resource allocations (CPU, memory, disk I/O) for process groups.

dockerkubernetesconceptbeginner

Kernel abstraction restricting what system resources (processes, network interfaces, mounts) a process tree can observe.

dockerconceptbeginner

Smallest deployable unit in Kubernetes, grouping co-located containers sharing network namespaces and storage volumes.

kubernetesconceptbeginner

Worker machine (physical or VM) running kubelet, container runtime, and kube-proxy in a Kubernetes cluster.

kubernetesconceptbeginner

Declarative controller managing stateless Pod replicas, progressive rollouts, and automatic rollbacks.

kubernetesconceptbeginner

Abstract network endpoint presenting a stable virtual IP and DNS name across a dynamic pool of Pods.

kubernetesconceptbeginner

API object managing external HTTP/HTTPS routing rules to cluster-internal Services.

kubernetesconceptintermediate

API object binding non-confidential key-value configuration data to Pod container environment variables or volume mounts.

kubernetesconceptbeginner

API object storing base64-encoded confidential credentials, certificates, or keys separately from image code.

kubernetesconceptbeginner

Workload controller managing stateful applications requiring unique network IDs and ordered volume provisioning.

kubernetesconceptintermediate

Mathematical operation computing context weights by comparing Query, Key, and Value vector dot-products.

gen-aiconceptintermediate

Sub-word atomic chunk created by tokenizers (e.g. BPE) mapping text strings to numerical vocabulary IDs.

gen-aiconceptbeginner

Dense numerical vector representing semantic meaning of text tokens in a continuous high-dimensional vector space.

gen-aiconceptbeginner

Maximum token capacity an LLM can digest in a single forward pass, spanning system prompts, history, and responses.

gen-aiconceptbeginner

Hyperparameter scaling logit probabilities before softmax to tune generation randomness and entropy.

gen-aiconceptintermediate

Sampling strategy filtering candidate tokens to the smallest set whose cumulative probability reaches threshold P.

gen-aiconceptintermediate

Process of updating LLM weights on specialized task datasets to adjust domain behavior or response formats.

gen-aiconceptadvanced

Autonomous software loop leveraging an LLM as its core reasoning engine to observe environments, plan, and execute tool calls.

agentic-aiconceptbeginner

Mechanism enabling LLMs to emit structured JSON payload calls invoking external APIs, scripts, or database queries.

agentic-aigen-aiconceptbeginner

State persistence architecture dividing context into short-term working context, long-term vector memory, and episodic logs.
