Study Notes
Computer System Components
- Physical structure consists of hardware components, while logical structure defined as Computer Organization.
- Computer Organization describes how components are interconnected and influence each other’s functionalities.
- Basic functioning principle: Input → Process → Output.
CPU and Computer Organization
- CPU is a key component composed of:
- ALU (Arithmetic Logic Unit): Executes arithmetic and logical operations.
- Control Unit: Directs the operations of the processor.
- Registers: Small storage locations that temporarily hold data, instructions, and addresses.
System Bus and Units
- Components of basic computer organization include:
- Input Unit: Captures and converts user input to digital form.
- Output Unit: Delivers processed data to the user.
- Storage Unit: Retains data and programs, can be volatile (RAM) or non-volatile (ROM).
- System Bus facilitates communication among the CPU, memory, and input/output units.
Compiler Functionality
- A compiler translates high-level programming code into machine code, enhancing execution speed by eliminating intermediate conversions.
Utility Software
- Utility software supports and enhances computer performance through functions like:
- Data backup
- Virus protection and eradication
- File management and optimization
- Common utilities include:
- Antivirus Software: Protects against malicious attacks.
- Disk Defragmenter: Optimizes disk performance by reducing fragmentation.
- Backup Utility: Duplicates data to recover from losses.
Device Drivers
- Device drivers are essential programs that enable communication between the operating system and hardware devices.
- Each hardware component has a specific driver that allows the operating system to recognize and utilize it effectively.
Custom and Proprietary Software
- Customized software is tailored to meet specific business needs and may not be suitable for other users without modifications.
- Proprietary Software is restricted in use and distribution, while Free Software allows for modification and redistribution.
- Free Libre Open Source Software (FLOSS) combines the principles of both free software and open source, allowing users the freedom to use, modify, and distribute it.
Software Categories
- Open Source Software (OSS): Source code is publicly available for modification without restrictions.
- Free Software: Users can use, change, and distribute without cost.
- Examples of FLOSS include Linux OS, MySQL, and OpenOffice.
Memory Types
- ROM (Read-Only Memory): Stores permanent instructions, not writable.
- RAM (Random Access Memory): Temporarily holds data for processing; it is writable and volatile.
Role of Operating Systems
- Operating systems manage hardware resources, offer user interfaces, and facilitate software applications to function correctly, ensuring overall computer operability.
