Study Notes
Types of Computers
- Supercomputer: Utilized in aerospace, automotive, chemical, electronics, and petroleum industries for complex computations and simulations.
- Mainframe Computer: Commonly used for Credit Card (CC) processing, capable of handling vast amounts of data and transactions.
- Microcomputer: Designed for personal and home use; smaller and less powerful.
- Hybrid Computer: Combines features of analog and digital computers, used in specific applications like hospitals for monitoring patients.
Computer Languages
- Machine Language: Comprises binary digits (0 and 1) only; directly understood by computers and consists of small instructions called mnemonic codes.
- Assembly Language: A low-level programming language that is machine-dependent and requires translation to machine language.
- High-level Language: More abstract, user-friendly, and machine-independent, enabling easier program writing and execution across different machines.
Programming Languages Match
- BASIC: Developed by John G. Kemeny and Thomas E. Kurtz in 1964, ideal for beginners.
- PASCAL: Created by Niklaus Wirth, focuses on structured programming.
- C++: Developed by Bjarne Stroustrup, supports object-oriented development.
- Python: Created by Guido van Rossum, known for its simplicity and readability.
- Java: Developed by James Gosling, widely used for cross-platform applications.
Classification and Application Areas
- Computers are classified by size (Micro, Mainframe) and purpose (general-purpose vs specific).
- Application areas vary based on type:
- Microcomputers: Personal computing, education, and small businesses.
- Mainframe Computers: Large-scale transaction processing in banks and corporations.
Low-level vs High-level Languages
- Low-level Languages:
- Closely related to the hardware; requires understanding of machine code.
- More efficient but harder to troubleshoot and less readable.
- High-level Languages:
- Easier to write, read, and maintain; closer to human language.
- Supports complex data structures and abstraction.
Advantages of High-level Languages
- Easier to learn and use compared to low-level languages.
- Enhanced productivity due to simplified syntax and constructs.
- Better portability across various machine architectures.
Fill in the Blanks
- A cell is the intersection of a row and a column in a table.
- Tables can be created using methods such as Insert Table and Draw Table.
- Merging combines two or more cells into one larger cell.
True or False
- Second-generation languages did use machine language: True
- Machine language has a defined syntax: False
- High-level languages have many advantages: True
- Mainframes are the most powerful and expensive: True
- C++ is an object-oriented language: True
