CPU & Processing
This measures how fast a CPU runs, usually in GHz.
What is clock speed?
This technology uses NAND flash and has no moving parts, making it faster than HDDs.
What is an SSD?
Something you know, something you have, and something you are are examples of this.
What are authentication factors?
This device assigns IP addresses automatically to devices on a network.
What is a DHCP server?
This language is used to query and manage relational databases.
What is SQL (Structured Query Language)?
Memory that loses its data when the power is turned off.
What is RAM? (Volatile)
This storage type connects directly to the motherboard and is very fast.
What is NVMe (M.2 SSD)?
A fake login page designed to steal credentials is an example of this type of attack.
What is phishing?
This protocol translates domain names into IP addresses.
What is DNS?
A table column that uniquely identifies each record is called this.
What is a primary key?
"Virtual cores" or logical sequences of instructions that allow a physical CPU core to manage multiple tasks simultaneously, significantly enhancing multitasking performance.
What are CPU threads?
This RAID level provides redundancy by mirroring data, but cuts usable storage capacity in half.
What is RAID 1?
Malware that locks files and demands payment to restore access is known as this.
What is ransomware?
A network device that connects devices within the same LAN and uses MAC addresses.
What is a switch?
A command used to retrieve data from a database.
What is SELECT?
This process increases CPU speed beyond its default settings.
What is overclocking?
This type of memory is non-volatile and used to store firmware like BIOS/UEFI.
What is ROM (or flash memory/EEPROM)?
This principle gives users only the access necessary to perform their job.
What is least privilege?
A user has a valid IP but cannot reach websites by name, only by IP address. The issue is likely this.
What is a DNS issue?
Storing duplicate data in multiple tables can cause inconsistencies and is avoided through this principle.
What is data integrity (or normalization)?
This type of memory inside the CPU stores frequently used data for faster access.
What is cache?
A system with 8GB RAM and heavy multitasking starts using disk space as memory, slowing performance significantly.
What is paging (virtual memory usage)?
It provides proof that someone or something performed a specific action.
Nonrepudiation
This broadband connection is incredibly fast and more expensive than DSL or cable.
Fiber- optic
In a database, this is the term for a collection of related fields that represents all the information about one person or entity.
What is a record (or row)?
