Most modern CPU architectures include both types of registers. Internal registers include the instruction register (IR), memory buffer register (MBR), memory data register (MDR), and memory address register (MAR). The ..
Process Definition A process is a program that is running on your computer. This can be anything from a small background task, such as a spell-checker or system events handler to a full-blown application like Internet Explorer or Microsoft Word. All processes are composed of one or more threads. Since most operating systems have many background tasks running, ..
Kernel Definition A kernel is the foundational layer of an operating system (OS). It functions at a basic level, communicating with hardware and managing resources, such as RAM and the CPU. Since a kernel handles many fundamental processes, it must be loaded at the beginning of the boot sequence when a computer starts up. The kernel performs a system check and recognizes components, such as ..
DirectX Definition DirectX is a set of standard commands and functions that software developers can use when creating their programs.

RTE Definition Stands for “Runtime Environment.” As soon as a software program is executed, it is in a runtime state. In this state, the program can send instructions to the computer’s processor and access the computer’s memory (RAM) and other system resources. When software developers write programs, they need to test them in the runtime environment. Therefore, ..
