What is the primary difference between symmetric and asymmetric encryption?
Symmetric encryption uses the same key for encryption and decryption, while asymmetric uses a public and private key pair.
Symmetric encryption uses different keys for encryption and decryption, while asymmetric uses a single shared key.
Symmetric encryption is always slower than asymmetric encryption.
Asymmetric encryption does not support digital signatures.
Symmetric encryption uses one secret key for both encryption and decryption, making it faster but requiring secure key distribution. Asymmetric encryption uses a public key for encryption and a private key for decryption, enabling secure key exchange and digital signatures. Each method has trade-offs in performance and security.

Cheat Sheet
Operating System Memory Management -
Understand how virtual memory and paging work by mapping logical addresses to physical frames; for example, the LRU (Least Recently Used) algorithm replaces the page not accessed longest, optimizing RAM use (source: University of California, Berkeley CS61). Remember that page tables track these mappings, and modern OS kernels use demand paging to load only needed pages. Mastering this concept is vital for the RGCSM exam quiz's hardware software networking trivia section.
CPU Instruction Cycle & Caching -
Review the Fetch-Decode-Execute cycle with the mnemonic "FDE" and learn how pipelining accelerates instruction throughput (source: Intel® 64 and IA-32 Architectures Developer's Manual). Know cache hierarchy (L1, L2, L3) and why high hit rates reduce memory latency in any computer technology quiz. A quick tip: twice as many cache levels can cut average memory access time by over 50%.
OSI Model Layer Functions -
Memorize the seven OSI layers - Physical, Data Link, Network, Transport, Session, Presentation, Application - using "Please Do Not Throw Sausage Pizza Away" (source: Cisco Networking Academy). Each layer has a defined role, from electrical signals at Layer 1 to encryption and interface processes at Layer 6. This foundation is key for basic networking questions on any online IT knowledge test.
Software Licensing Models -
Differentiate open-source versus proprietary licenses: GPL requires derivative works also be open (copyleft), while MIT is permissive, allowing closed-source redistribution (source: opensource.org). Recognizing these terms helps you advise on legal compliance in IT projects. This distinction often appears in the RGCSM exam quiz's software section, so keep examples of each license handy.
Encryption Methods in IT Security -
Contrast symmetric (AES with 128/256-bit keys) and asymmetric (RSA using two large primes and Euler's totient φ(n) for key generation) encryption (source: NIST Cryptographic Standards). Remember "same key" versus "public/private key pair" to quickly identify which method suits speed or secure key exchange. Strong encryption fundamentals bolster your score on any computer technology quiz and network security trivia.
