DATA & INFORMATION
Data and information are similar terms, but they have different meanings.
Data are raw data, images, or observations that have not been meaningfully organized or processed. It can be a number, text, image, sound, or any other representation of reality. Information is often considered raw and has no context or meaning of its own.
Information, on the other hand, is information that has been processed, organized, or interpreted in a way that provides context and meaning.
It is the result of analyzing, organizing and presenting information in a way that is useful and understandable. Information provides information, insight, or understanding that can be used for decision making, problem solving, or communication.
Consider the numbers to show the difference: 5, 7, 3, 9, 2. These numbers represent knowledge. But if we sort them in ascending order and calculate their average, "the average of the numbers is 5.
2 “We turn data into data. Data gives numbers context and meaning, making them meaningful and meaningful.

COMPUTER ARCHITECTURE
Computer architecture refers to the structure and organization of computer systems, including their components and their interrelationships. It includes the design principles and techniques used to design computers and software, and the relationship between hardware and software components.
Here are some important aspects of computer architecture:
Instruction Set Architecture (ISA): ISA defines the instructions and types of instructions a computer can execute. By acting as a bridge between hardware and software, it allows software developers to write programs that can run on different computers with ISAs.
Central Processing Unit (CPU): The CPU is the "brain" of the computer and does most of the processing.
It contains a control unit that carries instructions and controls operations, and an arithmetic logic unit (ALU) that performs arithmetic and arithmetic operations.
Memory hierarchy: Computers use different levels of memory to store and store information. The memory hierarchy typically includes registers, cache, main memory (RAM), and secondary devices such as hard drives or steady-state drives. These tiers differ in capacity, speed, and cost; primary storage is the fastest but smallest and most expensive, and secondary storage is the slowest but largest and most expensive.
Input/Output (I/O) System: The I/O system provides communication between the computer and external devices such as keyboard, mouse, monitor, printer, and storage device.
They enable computers to interact with the outside world by providing connections and processes for data transfer.
Parallelism and Pipeline: Computer architectures often use parallelism to improve performance. Parallel processing involves the simultaneous execution of multiple instructions or operations using multiple processors or dividing the tasks of different tasks in one processor. Pipelining is a technique that breaks down instructions into smaller steps and maximizes all resources by allowing multiple instructions to be executed simultaneously.
System Bus and Interconnect: A bus or interface is a system that provides communication and data transfer between various components of a computer, such as the CPU, memory, and I/O equipment.
They provide a way to transfer signals, addresses, and information between different parts of the body.
Power and Energy Management: Computer architecture also includes issues of power consumption and energy management. The design of electronic devices is important for portable devices, data centers and computing environments.
Computer architecture is a broad field that includes the design of individual components and the entire organization of computer systems. Designers and engineers seek to increase efficiency, effectiveness and reliability while balancing cost and limitations.
