How Much Do You Actually Know About Computer RAM? - Quiz

Random Access Memory (RAM) is a temporary data storage which can access data in random order and process it very fast to acquire a particular bit of information. It's also known as volatile memory as data can't be retained if there is no power. This quiz has been created to test your basic knowledge about computer RAM upgradation, identifying RAM and recent technologies. So, let's try out the quiz. All the best!


Questions and Answers
  • 1. 

    What type of ram has a 32-bit data path and has an access time of 60-80 nanoseconds?

    • A.

      Dimm

    • B.

      Simm

    • C.

      Rimm

    • D.

      SDR Dimm

    Correct Answer
    B. Simm
    Explanation
    A SIMM (Single In-Line Memory Module) is the correct answer because it is a type of RAM that has a 32-bit data path and an access time of 60-80 nanoseconds. SIMMs are older memory modules that were commonly used in computers before the introduction of DIMMs (Dual In-Line Memory Modules). DIMMs have a wider data path and faster access times, making SIMMs less common in modern computer systems.

    How many notches are on a DDR SDRAM module?

    • A.

      1

    • B.

      2

    • C.

      3

    • D.

      5

    Correct Answer
    B. 2
    Explanation
    A DDR SDRAM module typically has two notches. These notches are used to ensure that the module is inserted correctly into the memory slot on the motherboard. The notches act as a guide to align the module in the correct orientation, preventing any damage to the module or the motherboard.

    Computer memory which allows simultaneous read and writes operations is

    • A.

      ROM

    • B.

      RAM

    • C.

      EPROM

    • D.

      EEPROM

    Correct Answer
    B. RAM
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that allows for simultaneous read and write operations. Unlike ROM (Read-Only Memory), which can only be read from, RAM allows data to be both read and written to at any time. This makes it a versatile and essential component of a computer system, as it allows for the temporary storage and retrieval of data that is actively being used by the CPU. RAM is volatile memory, meaning that its contents are lost when the power is turned off, unlike non-volatile memory types such as ROM, EPROM, and EEPROM.

     In a computer, RAM stands for

    • A.

      Readily available memory

    • B.

      Read and more memory

    • C.

      Random access memory

    • D.

      Remember all memory

    Correct Answer
    C. Random access memory
    Explanation
    RAM stands for random access memory. This is a type of computer memory that allows data to be accessed in any order, regardless of its physical location. It is called "random access" because the computer can directly access any memory location, unlike other types of memory where data has to be accessed sequentially. RAM is a volatile memory, meaning that its contents are lost when the computer is powered off or restarted. It is used to store data that is currently being used by the computer's operating system, software, and applications.

  • 5. 

    Computer chip which retains its contents indefinitely without constant electronic refreshment is

    • A.

      Dynamic RAM

    • B.

      Dynamic ROM

    • C.

      Static RAM

    • D.

      Static ROM

    Correct Answer
    C. Static RAM
    Explanation
    Static RAM (SRAM) is a type of computer chip that can retain its contents indefinitely without the need for constant electronic refreshment. Unlike dynamic RAM (DRAM), which requires regular refreshing to maintain data, SRAM uses flip-flop circuits to store information, allowing it to hold data as long as power is supplied. This makes SRAM faster and more reliable than DRAM, although it is also more expensive and requires more space on the chip. Therefore, the correct answer is static RAM.

    Rate this question:

  • 6. 

    Computer memory which is used to store programs and data currently being processed by CPU is

    • A.

      Mass memory

    • B.

      RAM

    • C.

      Non volatile memory

    • D.

      PROM

    Correct Answer
    B. RAM
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that is used to store programs and data currently being processed by the CPU. Unlike mass memory or non-volatile memory, RAM is volatile, meaning that its contents are lost when the computer is powered off. PROM (Programmable Read-Only Memory) is a type of non-volatile memory that can be programmed only once. Therefore, the correct answer is RAM.

  • 7. 

    How often does a memory controller automatically refresh memory in dynamic RAM?

    • A.

      Once every minute

    • B.

      A few times per second

    • C.

      Thousands of times per second

    • D.

      30 minutes

    Correct Answer
    C. Thousands of times per second
    Explanation
    A memory controller automatically refreshes memory in dynamic RAM thousands of times per second. This is necessary because dynamic RAM stores data in capacitors, which tend to leak charge over time. To prevent data loss, the memory controller constantly refreshes the memory by reading and rewriting the data. This ensures that the charge in the capacitors is maintained and the data remains intact. Refreshing the memory thousands of times per second helps to ensure the stability and reliability of the data stored in dynamic RAM.

    On what substance are memory cells etched?

    • A.

      Copper

    • B.

      Silicon

    • C.

      Plastic

    • D.

      Iron

    Correct Answer
    B. Silicon
    Explanation
    Memory cells are etched on silicon. Silicon is a widely used material in the semiconductor industry due to its excellent electrical properties. It is a semiconductor material that can be easily manipulated to create electronic components such as transistors and memory cells. Silicon-based memory cells are commonly used in various electronic devices, including computer memory chips, due to their ability to retain information even when the power is turned off.

    What sets static RAM apart from dynamic RAM?

    • A.

      Dynamic RAM is faster than static RAM.

    • B.

      Static RAM is faster than dynamic RAM

    • C.

      There isn't much of a difference between static and dynamic RAM.

    • D.

      None

    Correct Answer
    C. There isn't much of a difference between static and dynamic RAM.
    Explanation
    The correct answer is "There isn't much of a difference between static and dynamic RAM." This answer suggests that static RAM and dynamic RAM are similar in terms of their characteristics and performance. It implies that there is no significant advantage or disadvantage of using one over the other.

    Memory chips are normally available as part of what type of card?

    • A.

      Printed circuit board

    • B.

      Module

    • C.

      Memory bank

    • D.

      None

    Correct Answer
    B. Module
    Explanation
    Memory chips are normally available as part of a module. A module is a self-contained unit that includes the memory chip along with other necessary components, such as a circuit board and connectors. This allows for easy installation and replacement of memory in various devices, such as computers and smartphones. The module can be easily inserted into a compatible slot, making it convenient for users to upgrade or expand their device's memory capacity.
