What is a Composite Input Device? Types and Examples Direct Answer: A composite input device is a hardware peripheral that combines multiple distinct input mechanisms (such as buttons, joysticks, touchpads, and motion sensors) into a single physical unit. Examples include modern gaming controllers, virtual reality (VR) handhelds, and interactive graphics tablets. What is a Composite Input Device in Computer Architecture? Composite input devices combine multiple peripherals like analog sticks, triggers, and motion sensors into a single unified hardware unit. Unlike traditional single-purpose peripherals (like a simple mouse or standalone keyboard), a composite device merges two or more input capabilities into one interface. This allows users to send multiple types of data commands—such as spatial coordinates, tactile keypresses, and rotational movement—simultaneously to the operating system using a single USB port or wireless connection.

What is cache memory? How is it different from primary memory? Definition of cache memory Cache memory is a high speed memory built in the processor and used between the main memory and the processor. 1. Cache is memory is placed between the CPU and the main memory. fig: describe the cache works between CPU & main memory. 2. Cache memory is faster than the main memory . fig: The Cache memory is faster than the main memory according to working performance. 3. Its access time is less than the main memory . fig: Cache performance of access time lower than main memory. 4. According to measurement the cache memory access time is 10 to 30 nano second (ns) and the main memory access time is 80 (ns) nano second . table of access time of both memory. 5. The Cache memory stores instructions and data that are immediately executed. fig describes that cache memory stores Instructions & Data but sometimes it don't stores data. 6....
