Explanation: The Dynamic Random Access Memory is the lowest cost, highest density random access memory available. Nowadays, computers use DRAM for main memory. However, it’s access time is more compared to SRAM.

Explanation: The Dynamic Random Access Memory is the lowest cost, highest density random access memory available. Nowadays, computers use DRAM for main memory. However, it’s access time is more compared to SRAM. The memory size of DRAM lies between 16 to 256 MB.

Explanation: Capacitor has high storing capability only, so DRAM stores its binary information in the form of electric charges on capacitors. However, DRAM takes more time time to access data.

Explanation: Most modern operating systems employ a method of extending RAM capacity, known as virtual memory. Virtual memory is seen as part of main memory but is actually a secondary memory.

Explanation: DRAM uses of integrated MOS capacitors as memory cell instead of a flip-flop. The advantage of this cell is that it allows very large memory arrays to be constructed on a chip at a lower cost per bit than in static memories.

Explanation: The disadvantage of MOS capacitor in DRAM is that it can’t hold the stored charge over a long period of time and it has to be refreshed every few millisecond. Thus, DRAM is slow in operation.

Explanation: The dynamic RAM offers reduced power consumption and large storage capacity in a single memory chip. With the availability of such high packing density memory ICs, the capacity of memory will continue to grow. However, it’s access time is more and thus operation is slow.

Explanation: The main memory of a PC is made of cache and DRAM. DRAM offers reduced power consumption and large storage capacity in a single memory chip.

Explanation: Most modern operating systems employ a method of extending RAM capacity, known as virtual memory which consists of SRAM.

Explanation: Dynamic RAM is used as main memory in a computer system as it has a higher speed due to the presence of MOSFET technology. However, it’s access time is more compared to SRAM and operation is slow.

Explanation: In a computer, cache memory acts between CPU and RAM.

Explanation: RAM is volatile. Therefore, it stores data only as long as the d.c power is on.

Explanation: A Dynamic RAM usually employs a technique called address multiplexing to reduce the number of address lines and thus the number of input/output pins on the IC package.

Explanation: A Dynamic RAM usually employs a technique called address multiplexing to reduce the number of address lines and thus the number of input/output pins on the IC package. Address multiplexing has 214 = 16384 bits.

Explanation: A sense amplifier for each column is necessary to convert from the low voltage and low energy to a sufficient level on the I/O data line.
