T Levels - Memory and Storage of a computer

What type of memory is used to store the BIOS or firmware of a computer and retains its content even when the power is off?

• RAM

  (Random Access Memory)

• ROM

  (Read-Only Memory)

• SRAM

  (Static Random Access Memory)

• DRAM

  (Dynamic Random Access Memory)

Which type of memory is volatile, meaning it loses its contents when the power is turned off?

• RAM

• ROM

• Flash Memory

• EPROM

  (Erasable Programmable Read-Only Memory)

What does "SDRAM" stand for?

• Synchronous Dynamic Random Access Memory
  

• Sequential Dynamic Random Access Memory

• Synchronous Dual Random Access Memory

• Super Dynamic Random Access Memory

What type of memory is typically used as the main working memory in a computer system?

• RAM

• ROM

• Flash Memory

• EPROM

What is the primary advantage of Solid State Drives (SSDs) over Hard Disk Drives (HDDs)?

• Greater storage capacity

• Faster data access and retrieval

• Lower cost per gigabyte

• Longer lifespan

What is the primary function of computer memory?

• • To store programs and data that are currently in use

• To process data and execute instructions

• To provide power to the computer components

• To store data permanently

Which type of computer memory is volatile and loses its data when the power is turned off?

• • Hard Drive

• SSD (Solid State Drive)

• ROM (Read-Only Memory)

• RAM (Random Access Memory)

What is memory refreshing in the context of computer memory?

• • The process of updating software to the latest version

• The periodic rewriting of data in DRAM (Dynamic RAM) cells to prevent data loss

• The process of clearing the cache memory

• The defragmentation of hard drives

Why do DRAM cells require refreshing?

• • They are faster than SRAM cells

• They have a simpler structure that leaks charge over time

• They consume more power than SRAM cells

• They are non-volatile memory cells

What is cache memory?

• • A type of memory that stores data permanently

• A small, high-speed memory located close to the CPU to store frequently accessed data and instructions

• A type of external storage device

• A memory used exclusively for graphic processing
