One small general comment here. For a number of these DPDK-specific terms
we should provide a cross-reference to locations in the docs for more
information. For example EAL should link to the programmers guide doc
chapter. The kernel modules for DPDK on FreeBSD should link to the GSG
chapter where we explain about their use, etc.

+Glossary
+========
+
+This glossary provides definitions for key terms and concepts used within DPDK. Understanding these terms will help in comprehending the functionality and architecture of DPDK.
+
+**BIOS (Basic Input/Output System)**
+
+The firmware used to perform hardware initialization during the booting process and to provide runtime services for operating systems and programs.
+
+**Bifurcated Driver**
+
+A driver model that splits functionality between kernel and userspace, often used in high-performance networking.
+
+**Clang-LLVM**
+
+A compiler toolchain that includes the Clang C compiler and LLVM linker, used for building DPDK on Windows.
+
+**contigmem Module**
+
+A module in FreeBSD that provides physically contiguous memory allocation used by DPDK.
+
+**DMA (Direct Memory Access)**
+
+A feature that allows hardware devices to access the main system memory directly, without involving the CPU.
+
+**EAL (Environment Abstraction Layer)**
+
+The layer within DPDK that abstracts environmental specifics and provides a standard programming interface.
+
+**hugepages**
+
+Large memory pages used by the operating system to manage memory more efficiently, especially in high-performance applications like DPDK.
+
+**IOMMU (Input-Output Memory Management Unit)**
+
+A hardware component that translates device-visible virtual addresses to physical addresses, providing memory protection and isolation.
+
+**MinGW-w64 Toolchain**
+
+A development environment for creating Windows applications, used as an option for compiling DPDK on Windows.
+
+**NIC (Network Interface Card)**
+
+A hardware component that connects a computer to a network.
+
+**nic_uio Module**
+
+A UIO driver for network devices in FreeBSD, used by DPDK.
+
+**NUMA (Non-Uniform Memory Access)**
+
+A computer memory design used in multiprocessing where the memory access time depends on the memory location relative to the processor.
+
+**PMD (POLL Mode Driver)**
+
+A type of driver in DPDK that continuously polls for events rather than relying on interrupts, often used for high-performance networking.
+
+**SoC (System on a Chip)**
+
+An integrated circuit that integrates all components of a computer or other electronic system into a single chip.
+
+**UIO (Userspace I/O)**
+
+A Linux kernel module that enables user-space applications to access hardware devices directly.
+
+**VFIO (Virtual Function I/O)**
+
+A kernel driver that allows a virtual machine to access physical devices directly, used in DPDK for device assignment.
+
+**VFIO Platform**
+
+A framework in Linux that allows exposing direct device access to userspace, in a secure, IOMMU-protected way.
