One-liner

The Clock is the component responsible for setting and synchronizing the timing of operations in a computer system.

One-liner

RAM stands for Random Access Memory, which is the computer's primary volatile memory used for temporary data storage during operation.

One-liner

CPU speed is measured in Gigahertz (GHz), which indicates the clock speed or the number of cycles a processor can execute per second.

One-liner

The Von Neumann architecture consists of the Control Unit, ALU, Memory Unit, and their interconnections, but I/O Interface is not a core component of this architecture.

One-liner

The fastest memory in the memory hierarchy is Registers.

One-liner

The ALU (Arithmetic Logic Unit) performs Arithmetic & logical operations in the CPU.

One-liner

SRAM (Static RAM) is the fastest type of volatile RAM because it uses flip-flops to store each bit and does not need periodic refreshing.

One-liner

Cache Memory is the fastest memory in a computer, designed to provide high-speed data access to the processor.

One-liner

Von Neumann architecture uses a single shared memory for both instructions and data, not separate instruction and data memory.

One-liner

The speed of CPU is measured in MHz (Megahertz) or GHz (Gigahertz).
