Which addressing mode helps to access table data in memory efficiently?

Which addressing mode helps to access table data in memory efficiently? Correct Answer Index mode

Indexed addressing mode is widely used in accessing data elements of look-up table entries.

Points about Indexed Addressing Mode :

  • Indexed addressing mode is the sequential control flow memory-based addressing mode, which is mainly used to access the Arrays/Table data.
  • In this mode of accessing two parameters are required i.e, Base address and the Index value.
  • In this mode effective address is updated by adding the constant to the content of an Index register i.e,

EA = Address field value + , where address field value contains the starting address of the array and index register contains the position of the array element.

Consider a process executing on an operating system that uses demand paging. The average time for a memory access in the system is M units if the corresponding memory page is available in memory, and D units if the memory access causes a page fault. It has been experimental measured that the average time taken for a memory access in the process is X units. Which one of the following is the correct expression for the page fault rate experienced by the process?
Assume a memory access to main memory on a cache "miss" takes 30 ns and a memory access to the cache (on a cache "hit") takes 3 ns. If 80% of the processor's memory requests results in a cache "hit", what is the average memory access time?
With regard to computer memory, which of the following statement(s) is/are TRUE?  (A) Cache memory is 'volatile' memory. (B) Magnetic memory is 'volatile' memory.  (C) Flash memory is 'volatile' memory. (D) RAM is 'volatile' memory. Choose the correct answer from the option given below:
Consider a single-level page table system. with the page table stored in the memory. If the hit rate to TLB is 80%, and it takes 15 nanoseconds to search the TLB. and 150 nanoseconds to access the main memory, then what is the effective memory access time, in nanoseconds ?
Which of the following statements are true?
Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
Consider the statements given below- A: Relationship between Mean, Median and Mode is : Mode = 3 Median – 2 Mean B: It is also possible that there can be more than one mode or no mode for a data set. C: In a data set, half of the data points are smaller than the median and half of the data points are larger. Which of the above statement(s) is/are TRUE?

Which of the following memory-based addressing mode satisfies the below statements? 1. The address of the memory location that holds the operand is included in the instruction. 2. The effective address is the address part of the instruction. 3. It is used to access the static variables.
Consider a hypothetical processor with an instruction of type LW R1, 20(R2), which during execution reads a 32-bit word from memory and stores it in a 32-bit register R1. The effective address of the memory location is obtained by the addition of constant 20 and the contents of register R2. Which of  the  following best reflects the addressing mode implemented by this instruction for the operand in memory?
