Protocol

/ˌeɪtʃ.tiː.tiːˈpiː ˈhɛd.ərz/

noun — “the envelope of your web requests telling servers how to handle your data.”

HTTP Headers are metadata sent along with HTTP requests and responses that provide essential information about the communication between clients and servers. They define how content should be handled, cached, authenticated, or displayed, and can include data about the browser, content type, language preferences, and more. Proper use of HTTP Headers improves security, performance, and compatibility.

/ˈnɛt.wɜːrk ˈproʊ.tə.kɒl/

noun — “the rulebook that keeps your data from turning into digital chaos.”

Network Protocol is a standardized set of rules and conventions that govern how devices communicate over a network. It defines how data is formatted, transmitted, received, and interpreted, ensuring that different systems, operating systems, and applications can exchange information reliably and efficiently. From sending a simple email to streaming high-definition video, Network Protocols are the invisible traffic controllers keeping everything orderly.

/ˌɛsˌɛˈɛ/

noun — "keeping the server chatty with your browser without spamming the world."

SSE, Server-Sent Events, is a web technology that allows servers to push real-time updates to browsers over a single HTTP connection. Unlike WebSockets, SSE is unidirectional—the server sends events to the client, which listens and reacts without needing to constantly poll for updates.

/ˌɛs-ɛn-ɛm-ˈpi/

noun — "the polite protocol that asks devices how they’re doing, then reports back."

SNMP, Simple Network Management Protocol, is a standard protocol used in information technology for managing and monitoring devices on IP networks. It allows network administrators to collect device data, configure network equipment, and receive alerts about operational or performance issues. SNMP is widely used for routers, switches, servers, printers, and other networked devices.

Technically, SNMP involves:

/ˌɛm.kjuːˌtiːˈtiː/

noun — "lightweight messaging protocol for IoT devices."

MQTT , short for Message Queuing Telemetry Transport, is a lightweight, publish-subscribe messaging protocol optimized for constrained devices and low-bandwidth, high-latency, or unreliable networks. It enables efficient, asynchronous communication between clients and brokers, making it widely used in Internet of Things (IoT) applications.

/ˈkɑːfkə/

noun — "high-throughput distributed event streaming platform."

Kafka is a distributed event streaming platform designed for high-throughput, fault-tolerant, and scalable messaging. It implements a **publish-subscribe** model where producers publish messages to topics, and consumers subscribe to those topics to receive messages asynchronously. This architecture decouples producers and consumers, enabling independent scaling and real-time data processing across distributed systems.

/pʌb ˈsʌb/

noun — "asynchronous messaging model for decoupled communication."

Pub/Sub (short for Publish/Subscribe) is a messaging pattern in which senders (publishers) do not send messages directly to specific receivers (subscribers), but instead categorize messages into channels or topics. Subscribers express interest in one or more topics and receive only messages that match those topics. This decouples the sender and receiver, enabling scalable, asynchronous communication across distributed systems.

/ræft/

noun … “Simplified consensus algorithm for distributed systems.”

/ˈpæk.sɒs/

noun … “Consensus algorithm for unreliable networks.”

Paxos is a fault-tolerant Consensus algorithm designed to achieve agreement among nodes in a Distributed System, even when some nodes fail or messages are delayed or lost. It ensures that a single value is chosen and consistently replicated across all non-faulty nodes, providing a foundation for reliable state machines, replicated databases, and coordination services.

/ˈwaɪˌfʌɪ ˈlæn/

noun — "a local network that connects devices wirelessly."

WLAN, short for Wireless Local Area Network, is a network that allows devices such as computers, smartphones, and IoT (IoT) devices to communicate and share resources without physical cables. WLANs use radio waves to transmit data, typically following IEEE 802.11 standards, and provide the flexibility and mobility that wired LANs cannot offer.
