DNS stands for Domain Name System, which translates human-readable domain names into IP addresses that machines use to identify each other on the network. It functions like a phone book for the Internet. DNS servers handle queries from clients, returning the corresponding IP address. More at .
What RAID level provides mirroring without striping?
RAID 10
RAID 5
RAID 0
RAID 1
RAID 1 implements disk mirroring by duplicating the same data onto two or more drives, providing redundancy but no striping. RAID 0 offers striping for performance but no mirroring. RAID 5 provides parity-based fault tolerance with striping, and RAID 10 combines mirroring and striping. Read more at .
Which service resolves domain names to IP addresses?
DHCP
DNS
HTTP
FTP
The DNS (Domain Name System) service resolves human-friendly domain names into IP addresses that networking equipment uses to route data. DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to devices, while HTTP and FTP are application-layer protocols for web and file transfer respectively. DNS is critical for everyday internet browsing. See .
What is the primary difference between a 32-bit and a 64-bit operating system?

Cheat Sheet

  1. Essential PC Hardware Components -

    Get to know your CPU, RAM and storage inside out: the CPU's clock speed (measured in GHz) drives processing power, while RAM holds active data for lightning-fast access and storage (HDDs or SSDs) archives your files permanently. Use the mnemonic "C.R.S." (CPU-RAM-Storage) to recall the core trio when reviewing computer essentials for a computer basics quiz.

  2. Operating System Roles & File Management -

    An OS manages hardware resources, provides a user interface, schedules processes and safeguards data through built-in security layers (source: CS50 course materials). Remember the four core functions - Hardware control, UI delivery, process scheduling and file management - to ace any software fundamentals quiz or digital literacy test.

  3. System vs. Application Software -

    System software (like Windows, macOS or Linux kernels and device drivers) sits between hardware and apps, while application software (e.g., word processors, browsers, games) helps you perform tasks. A handy trick: "S + A = Satisfy" reminds you that System precedes Application in the boot sequence and daily workflows (CompTIA A+ reference).

  4. Binary & Data Measurement Units -

    All data is stored in binary, where 1 byte = 8 bits and 1 KB = 1,024 bytes (not 1,000!). Use the rhyme "Bits are small, bytes stand tall" to cement this in memory for your computer skills quiz and speed through any conversion question.

  5. Basic Networking Concepts -

    Familiarize yourself with LAN vs. WAN, IP addressing (IPv4's four octets ranging 0 - 255) and DNS lookup processes to connect names with numbers. Visualize the OSI model's seven layers as "Please Do Not Throw Sausage Pizza Away" to recall each layer's role during a PC hardware quiz or software fundamentals quiz.
