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.

The Processor

Comprises the system board (motherboard) hosting integrated circuits.
- Includes the CPU, memory (RAM and ROM), and expansion slots.
CPU:
- Executes software program instructions.
- Communicates with RAM and other input devices.
- Acts as the brain of the computer.
