It's a problem caused by the data bus which is a lot slower than the rate at which the CPU can carry out instructions. → von Neumann bottleneck True False PHP's array data structure is a combination of what two data structures from other languages? Von Neumann Architecture Since the Instruction Memory and the Data Memory are the same, the Processor or CPU cannot access both Instructions and Data at the same time as they use a single bus. A computer program is made up of sets of instructions which are encoded using the binary numbering system. Random-access memory (RAM / r æ m /) is a form of computer memory that can be read and changed in any order, typically used to store working data and machine code. Assembly language instructions use abbreviations called mnemonics. Von Neumann architecture is composed of three distinct components (or sub-systems): a central processing unit (CPU), memory, and input/output (I/O) interfaces. As computers become faster, memory access speeds are keeping pace. 1. The three parts of the ALU together are known as the ____________________. 1.3 State Moore’s Law.

The CPU can either be reading an instruction from memory OR writing data to the memory. The von Neumann bottleneck is partially overcome in practice by using a very fast bus, called the memory bus, to connect the CPU, memory, and the PCI bus. The set of all operations that can be executed by a processor is called its I/O set. Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.
