2.4 GHz and 5 GHz are two different frequency bands used for Wi-Fi networks:
- 2.4 GHz: This is the most common Wi-Fi frequency band. It offers good range and works well through walls and other obstacles. However, because it’s a widely used frequency, it can suffer from interference from other devices like cordless phones and microwave ovens.
- 5 GHz: This frequency band provides faster data rates but over shorter distances. It’s less prone to interference because it’s less commonly used. 5 GHz Wi-Fi is often used for applications that require higher bandwidth, such as streaming HD video or online gaming.
Many modern Wi-Fi routers and devices support both 2.4 GHz and 5 GHz bands, allowing you to choose the one that best suits your needs for a particular situation. For example, you might use 2.4 GHz for better range throughout your home and 5 GHz for high-bandwidth activities when you’re closer to the router.

Bandwidth
The amount of data a connection can carry in a given time, usually measured in Mbps or Gbps. More bandwidth supports more users, devices, and simultaneous applications.
Broadband
A general term for always-on, high-speed Internet access. Broadband can be delivered over fiber, cable, DSL, fixed wireless, cellular, or satellite networks.
Cloud Computing
Computing resources—such as applications, servers, storage, or databases—delivered from remote infrastructure and scaled as requirements change.
Cybersecurity
The practices and controls used to protect identities, devices, networks, applications, and data from unauthorized access, disruption, or manipulation.
Identity and Access Management (IAM)
The systems and policies that determine who a user is, what resources they may access, and how that access is authenticated and reviewed.
API
An application programming interface is a defined way for software systems to exchange data or request functions from one another.
