Remaps

Remaps refer to the process of changing the mapping between two domains or spaces in order to reinterpret inputs, addresses, or resources. The term is used across computing, networking, and data processing to adapt systems without altering the underlying data.

In user interfaces, keyboard remapping changes which physical keys produce which input signals. It is implemented by software or firmware and is common for accessibility or ergonomic reasons, such as swapping Caps Lock and Control or creating custom shortcuts. Windows, macOS, and Linux provide native options or third‑party tools to configure remaps.

In hardware and memory systems, remapping redefines address or I/O layouts. Memory remapping can relocate RAM blocks or enable access to 64‑bit address spaces, while I/O remapping assigns devices to different buses or regions. BIOS/UEFI settings often control these mappings, sometimes to improve compatibility or virtualization support.

In networking and data pipelines, remapping entails rewriting addresses or routes. Examples include NAT or proxy servers remapping IP addresses and ports, and URL rewriting rules that alter paths for routing, caching, or security policies. Data‑level remapping may reassign keys or fields to match a different schema.

Remapping is typically reversible and configuration‑driven. Proper testing and documentation are important to avoid compatibility issues with software, firmware, and network equipment.
