Computing architecture is the high-level design of a computing system. It includes the hardware, software, communications, and control systems that make up a computing system.<\/p>\n

Computer architecture refers to the design of a computer system, which includes both hardware and software, as well as the overall organization of the system.<\/p>\n

What is meant by computer architecture? <\/h2>\n

Computer architecture is the organisation of the components which make up a computer system. It defines what is seen on the machine interface, which is targeted by programming languages and their compilers.<\/p>\n

There are three primary examples of computer architectures: the x86, the SPARC, and the PowerPC. The x86 is made by Intel and AMD, the SPARC is made by Sun Microsystems and others, and the PowerPC is made by Apple, IBM, and Motorola. Each architecture has its own unique strengths and weaknesses, so it’s important to choose the right one for your needs.<\/p>\n

What are the 3 categories of computer architecture <\/h3>\n

Microarchitecture:<\/p>\n

This is the lowest level of abstraction when discussing computer architecture. It deals with the physical components of the system, such as the number and types of CPUs, the amount of cache memory, and the size and speed of the buses.<\/p>\n

Instruction Cycles:<\/p>\n

An instruction cycle is the basic unit of work that the CPU performs. Each instruction cycle consists of fetching an instruction from memory, decoding it, and then executing it.<\/p>\n

Multicycle Architecture:<\/p>\n

Multicycle architectures are those that use more than one clock cycle to execute an instruction. For example, a four-cycle architecture would fetch an instruction in the first cycle, decode it in the second cycle, execute it in the third cycle, and write the results back to memory in the fourth cycle.<\/p>\n

Instruction Pipelining:<\/p>\n

Instruction pipelining is a technique for increasing the performance of a CPU by overlapping the execution of instructions. In a simple pipeline, instructions are fetched from memory, decoded, and executed in order. However, in a more sophisticated pipeline, instructions may be executed out of order, and multiple instructions may be in different stages of execution at the same time.<\/p>\n

Von-Neumann Architecture:
\nVon-Neumann architecture is a computer architecture based on a 1945 paper by Hungarian mathematician and physicist John von Neumann. The paper described a design architecture for an electronic digital computer with a central processing unit (CPU) that contains an arithmetic logic unit (ALU), memory, and input\/output devices. The architecture defines the relationship between these components.<\/p>\n

Harvard Architecture:
\nThe Harvard architecture is a computer architecture with physically separate storage and signal pathways for instructions and data. The term originated from the Harvard Mark I computer, which was built in 1937. It is also known as the split-bus architecture.<\/p>\n

Instruction Set Architecture:
\nAn instruction set architecture (ISA) is the interface between the computer’s software and hardware. It is the basic set of commands that a processor understands. An ISA includes a specification of the set of opcodes (machine language), the native commands supported by the processor.<\/p>\n

Micro-architecture:
\nMicro-architecture, also called computer organization, is the way a given instruction set architecture (ISA) is implemented in a particular processor. A given ISA may be implemented with different micro-architectures; implementations may vary due to different technologies<\/p>\n

Von Neumann architecture is a design principle used in most modern computers. It stipulates that one memory space be used for both instructions (software) and data. This design is efficient and versatile, but it can also be a source of bottlenecks and errors if not managed properly.<\/p>\n

A computer is made up of five main parts: the motherboard, the Central Processing Unit (CPU), the Graphics Processing Unit (GPU), Random Access Memory (RAM), and storage.<\/p>\n

The motherboard is the main circuit board of the computer and it is what everything else is connected to. The CPU is the main processing unit of the computer and it handles all the calculations and processing. The GPU is responsible for rendering images and graphics. RAM is a type of volatile memory that is used to store data temporarily. Storage is where all the data and files are stored permanently.<\/p>\n

What are the 4 main parts in a basic computer architecture? <\/h2>\n

The CPU is the main processing unit of the computer, and it is responsible for performing all the instructions given by the user. The input unit is responsible for taking in all the data and information from the user, and the output unit is responsible for displaying all the results of the instructions given by the user. The memory unit is responsible for storing all the data and information, and the control unit is responsible for controlling all the operations of the computer.<\/p>\n

There are different components in the computer system architecture, such as the input unit, output unit, storage unit, arithmetic logic unit, and control unit. The input data travels from the input unit to the arithmetic logic unit. Similarly, the computed data travels from the arithmetic logic unit to the output unit. The data constantly moves from the storage unit to the arithmetic logic unit and back again.<\/p>\n

Why is computer architecture important <\/h3>\n

In this subject, we explore how machines are designed, built, and operate. By understanding what’s inside and how it works, we can design, develop, and implement applications better, faster, cheaper, more efficiently, and easier to use. This knowledge allows us to make informed decisions instead of guestimating and assuming.<\/p>\n

Computer architecture is the logical design and physical implementation of a computer system. It describes the design of an electronic computer with its CPU, which includes the arithmetic logic unit, control unit, registers, memory for data and instructions, an input\/output interface and external storage functions. The term “computer architecture” is sometimes used to describe the functionality of a computer system, as opposed to the hardware that implements it.
