Cheat Sheet
- Operating System Principles -
Review core OS concepts such as process scheduling, memory management, and file systems to ensure smooth multitasking. Understand how paging and segmentation optimize RAM usage by mapping virtual addresses to physical memory (e.g., page tables versus segments). Use the mnemonic "MPF" (Memory, Processes, Files) to quickly recall these pillars during your it knowledge test.
- OSI Model and Networking Basics -
Master the seven layers of the OSI model - Physical, Data Link, Network, Transport, Session, Presentation, and Application - to diagnose connectivity issues and design robust networks. A popular mnemonic, "Please Do Not Throw Sausage Pizza Away," helps lock in layer order for it tests and it quiz questions. Don't forget to compare IPv4 and IPv6 addressing schemes (32-bit vs. 128-bit) when tackling real-world networking scenarios.
- Cybersecurity Fundamentals -
Focus on the CIA triad - Confidentiality, Integrity, and Availability - to build a strong security mindset for any information technology quiz. Study common encryption algorithms (AES, RSA) and hashing functions (SHA-256) as they form the backbone of secure data transmission. Remember that multi-factor authentication (MFA) exponentially improves defense against unauthorized access.
- CPU Performance and Hardware Components -
Analyze how CPU clock speed, cache hierarchy (L1, L2, L3), and instructions per cycle (IPC) affect overall performance; use the formula Execution Time = Instructions × CPI ÷ Clock Rate for quick calculations. Differentiate between DRAM and SRAM to understand why cache memory is faster but more expensive than main RAM. Reviewing motherboard bus speed and chipset functions can also give you an edge on your next IT test.
- Database Systems and Data Management -
Understand relational database concepts, including primary keys, foreign keys, and SQL commands like SELECT, INSERT, UPDATE, and DELETE for efficient data operations. Memorize the ACID properties (Atomicity, Consistency, Isolation, Durability) to ensure transactional integrity in any it test scenario. A simple mnemonic, "ACID - Always Care In Data," helps cement these critical principles in your memory.
