Study Notes
Hardware
- Refers to the physical components of a computer system, including devices such as a CPU, RAM, motherboard, hard drive, and peripheral devices like keyboards and mice.
- Integral for executing instructions and processing data; without hardware, software cannot function.
Operating System
- Acts as an intermediary between computer hardware and user applications, enabling communication and resource management.
- Manages hardware resources, including CPU scheduling, memory allocation, file systems, and input/output operations.
- Provides a user interface, allowing users to interact with the computer via command line or graphical interfaces.
Compiler
- Translates high-level programming language code into machine code or intermediate code, enabling the program to be executed by the hardware.
- Performs syntax checking and optimization, enhancing program performance and efficiency before execution.
- Essential for developers to write code in human-readable form while ensuring compatibility with computer systems.
Online Processing
- Refers to real-time data processing where data is processed immediately as it is received, allowing for instant updates and feedback.
- Commonly used in applications like banking, airline reservations, and e-commerce systems, where timely access and accuracy are critical.
Batch Processing
- Involves executing a series of programs or tasks without manual intervention, often collected in a batch to be processed at scheduled times.
- Typically used for processing large volumes of data where immediate processing is not necessary, such as payroll systems and data big analysis.
- Enhances efficiency by allowing computers to complete tasks in bulk, reducing idle time and resource wastage.
