1. Character sets, including ASCII and Unicode, and differences in capacity and range; lossless compression methods for text file size reduction; limitations of lossy compression for text.
2. Numerical data representation in hexadecimal, Binary Coded Decimal (BCD), and two's complement binary formats; calculations involving conversions and memory addressing.
3. Fetch-Execute cycle steps with register transfer notation, handling of interrupts, and instruction groups like data movement and logical operations.
4. Key management tasks of operating systems, including process, memory, and file management; utilities like backup and defragmentation software; security methods like encryption and firewalls.
5. Relational databases with primary and foreign key relationships, SQL for data manipulation and structure definition, and normalization to Third Normal Form (3NF).
6. Logic circuits and truth tables for NAND, OR, and NOT operations; cloud computing concepts, including public and private clouds; benefits and drawbacks of cloud services.
