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
