Macrokernel vs Microkernel Explained: How OS Kernels Manage Hardware Resources

The article explains that an operating system kernel orchestrates all hardware resources, compares macrokernel designs like Linux that place scheduling, memory, file system, networking, and drivers in a single privileged space for speed, with microkernel designs that isolate most services in user‑mode processes, highlighting trade‑offs in performance, reliability, and modern hybrid approaches.

Common Encryption Algorithms and Their Practical Characteristics

This article reviews the most widely used encryption, signature, and hash algorithms—including symmetric ciphers (DES, 3DES, AES, IDEA, SM4, RC4, ChaCha20), asymmetric schemes (RSA, ECC, ECDH, DSA/ECDSA, SM2), hash functions (MD5, SHA‑1, SHA‑2, SHA‑3, SM3) and password‑hashing primitives (bcrypt, scrypt, Argon2) — summarizing their key sizes, security status, typical use cases and compliance requirements.
