Cheat Sheet
- Hardware vs. Software Fundamentals -
Understand that hardware refers to physical components like CPUs and RAM, while software includes operating systems and applications (Source: IEEE Computer Society). A handy mnemonic is "HARDware Holds And Runs Data, SOFTware Serves On Functional Tasks." This clarity is vital for acing any computer test exam.
- Operating System Roles -
Recognize an OS as the bridge between hardware and user, managing processes, memory, and file operations (per Microsoft Learn). For example, Windows' Task Manager or Linux's top command shows real-time CPU and memory use. Mastering these basics boosts your confidence in any basic IT knowledge quiz.
- Networking Basics & OSI Model -
Learn the seven OSI layers: Physical, Data Link, Network, Transport, Session, Presentation, Application - remember with "Please Do Not Throw Sausage Pizza Away" (RFC 1122). Know that IP addressing (e.g., 192.168.0.1) operates at Layer 3 and TCP/UDP at Layer 4 (IETF). This foundation is key for a strong test on computer networking concepts.
- Data Storage & File Systems -
Differentiate block storage (e.g., HDD, SSD) from file systems like NTFS or ext4, which organize files in directories (Source: ACM Digital Library). Recall that 1 KB = 1,024 bytes and 1 MB = 1,024 KB in binary terms, a critical fact for capacity calculations. Solid grasp of storage fundamentals supports better performance on computer exams.
- Cybersecurity Principles (CIA Triad) -
Memorize the CIA triad: Confidentiality, Integrity, Availability - think "Lock, Check, Access" to remember each pillar (NIST guidelines). For instance, encryption ensures confidentiality, checksums validate integrity, and redundant systems uphold availability. These core concepts frequently appear in any basic IT knowledge assessment.
