What Are The Four Layers Of The Computer Architecture

What are the four layers of the computer architecture.
Sensing communication data and service. 1 point computer operating system software user hardware operating system software user binary hardware operating system software hardware windows software user 2. 1 point write a paragraph on examples of abstraction that you encounter in your day to day life. Other abstraction definitions may contain three layers.
Working up from there per the previously depicted layers of abstraction graph each of these layers is potentially vulnerable because of the human factor. 1 application 2 system software 3 hardware. In standard four layer architecture data is computed at all the layers including in sensors and actuators. Higher levels cover network requests and responses.
This layer interacts with the system hardware and coordinates with all the peripheral devices used such as printer mouse keyboard scanner etc. This layer deals with scheduling the processes for the cpu. The hardware layer is the lowest layer in the layered operating system architecture. This processing depends upon the processing limits of the iot equipment.

It conceptually divides computer network architecture into 7 layers in a logical progression. The business layer. These are objects you can physically hold in your hand. A computer can be cut into four main layers hardware operating system software and users.
Sensing the sensing layer has a varied set of iot. The hardware layer is made up of the physical components of a computer. In other definitions computer architecture involves instruction set architecture design microarchitecture design logic design and implementation. The information and communication technology ict architecture of a smart city has 4 layers.
The presentation layer. This is developed by humans and is therefore prone to errors. The lower layers deal with electrical signals chunks of binary data and routing of these data across networks. Details about the six layers are.
