In computer fields, computer architecture is a set of rules and ways that explain the functionality, organization and implementation of computer systems. Some definitions of computer architecture and organization describes the capabilities and programming model of a computer but not a particular implementation.
The term computer is used to describe a device made up of a combination of electronic and electro-mechanical (electronic and mechanical) components.
By itself, a computer has no intelligence and is referred to as hardware, which means simply the physical equipment. A computer can`t be used until it is connected to other parts of a computer system and software is installed.

The design, arrangement , construction or organization of the different parts of a computer system is known as Computer Architecture. It is the conceptual design and fundamental operational structure of a computer system.
It is a framework and functional description of requirements and design implementations for the various parts of a computer, focusing largely on the way by which the Central Processing Unit (CPU) performs internally and accesses addresses in memory.
It may also be defined as the science and art of selecting, interconnecting hardware components to create computers to meet functional performance and cost.
HISTORY
The first document of Computer Architecture was a correspondence between Charles Babbage and Ada Lovelace, that describes the analytical engine. Here is the example of other early important machines: John Von Neumann and Alan Turing.
Computer architecture is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible with economic status and as well as the technological constraints. In ancient period, computer architectures were designed and prepared on the paper and then, directly built into the final hardware form. Later, in today`s computer architecture, prototypes were physically built in the form of transistor logic (TTL) computer such as the prototypes of the 6800 and the PA-RISC tested, and tweaked before committing to the final hardware form.

LAYEROF COMPUTER ARCHITECTURE
Under the Computer architecture, it consists of 6 layers. They are as follows:
Electrical and electronic component levelDigital logic levelMicro programmed levelMachine levelSystem software levelApplication program level
Electrical and Electronic component level
Almost all the modern computer devices are built from a simple electric component such as transistors, capacitors, a resistor which works on suitable power supplies.
Digital logical level
All the basic operations of the machine are provided at this level. The basic element at this level can store, manipulate and transmit data in the simple binary form. These digital logic elements are called gates which are normally constructed or made from a small number of transistors and other electronic components.
The standard digital logic devices are combined together to form computer processor or computer memories.
Micro program level
In this level, a sequence of microinstruction constitutes the microprogramming, which we called firmware, which is permanently stored in ROM. At the time, when the computer was made without microprogram level processor, it was built from a combination of a digital logic component.
The use of micro programmed level enables a manufacturer to produce a family of processors all of which process the same set of machine instruction at the machine level which differs in terms of construction and speed.
Machine level
Several hardware levels are presented in machine level. These are the basic elements of the computer. They are processor, input/output device, main memory, auxiliary storage, etc.
System software level
The program that directs the internal operation of a computer system is called system software.
Application software level
The program directs the computer to solve user-oriented problems are called application software.
According to the Computer architecture, it has three subcategories:
