Study Notes
Types of Data Processed by Computers
- Numeric data: Essential for scientific and technical applications.
- Characters: Commonly required for business applications, often used alongside numeric data.
- Computers process data using programs, which are sets of instructions stored in memory.
Characteristics of Computers
- Input data: Information processed by computers, entered via input devices and stored in memory.
- Processing: The operation that transforms input data into output data.
- Display: Output results are presented on a monitor.
- Memory and program capability are crucial characteristics, along with speed and reliability.
Modes of Operation
- Batch Processing: Data is stored internally and processed sequentially. Utilized for large datasets.
- Classical batch: Utilizes punch cards.
- Modern batch: Uses time-sharing terminals.
- Interactive Processing: Involves parallel information processing in a conversational mode.
Generations of Computers
- Fourth Generation (1971-Present):
- Microprocessor-driven, consisting of multiple integrated circuits acting as the CPU.
- VLSI technology permits thousands of transistors on a single chip.
- Early microprocessors include Intel 4004 and subsequent models like 8008 and 8086.
- Other companies include Motorola, Texas Instruments, and Zilog.
- Fifth Generation:
- Focus on artificial intelligence technologies still under development.
- Emphasizes parallel processing and aims for computers that can understand natural language and self-organize.
Comparison of Computer Generations
- First Generation: Vacuum tubes used for processing.
- Second Generation: Transistors replaced vacuum tubes for smaller, more efficient systems.
- Third Generation: Integrated circuits emerged, marking the transition towards modern computing.
- Fourth Generation: Represents microcomputers such as personal desktops designed for single users.
Computer Basics and Fundamentals
- Computer structure divides into Hardware and Software.
- Hardware: Physical components of a computer system.
- Consists of five logical units:
- Input Unit: Devices like mouse and keyboard.
- Output Unit: Devices such as printers, monitors, and speakers.
- Memory Unit: Retains processed and input information.
- Central Processing Unit (CPU): Manages device operations.
- Secondary Storage Unit: Includes hard drives and floppy disks.
