Main memory is the storage that is directly available to the CPU of a computer and is made3 up of RAM and ROM. RAM's (Random Access Memory) purpose is to hold the data and instructions temporarily which the CPU will process. ROM's (Read Only Memory) function is to hold data necessary for starting up the computer permanently , whose contents cannot be changed by the user.

What does DRAM stand for in computer terms?

DRAM stands for Dynamic Random Access Memory


What is the electrical component used for memory logic?

The primary electrical component used for memory logic is the transistor. Transistors act as switches or amplifiers in digital circuits, enabling the storage and retrieval of binary data. In memory chips, such as SRAM (Static Random-Access Memory) and DRAM (Dynamic Random-Access Memory), arrays of transistors are utilized to hold and manipulate data. Additionally, capacitors are used in DRAM to store charges representing bits of information.


Why is DRAM analog device and SRAM digital device?

This is incorrect. DRAM is a digital device, and so is SRAM. DRAM and SRAM serve the same functions- temporary storage space (or random access memory, hence 'RAM') in different ways. DRAM data is typically refreshed every so often, uses more power than SRAM and is much slower, but also much cheaper and easier to manufacture in huge sizes. SRAM, such as the cache on CPUs, is much smaller and faster, and stores data until it is cleared or the computer is turned off (and in some cases, even without power) but is extremely expensive.


List the advantages of dynamic RAM compared with static RAM?

SRAM (static RAM).1. Memory maintains data in storage as long as it is powered. Because it is faster and more reliable and expensive than DRAM, SRAM is most often used as cache memory. Earlier forms of SRAM were classified as Async or Sync RAM if they were synchronized with the system clock.2. The most common type of SRAM today is pipeline burst SRAM, which can operate at higher bus speeds.DRAM (dynamic RAM).1.This type of RAM retains its data by being continuously rewritten every few milliseconds. Like SRAM, the data in storage is volatile, meaning it is lost when the system is not powered.2. DRAM is the most common type of expandable company memory in workstations and servers today, but there are several different types of DRAM.3. The advantage of DRAM is its structural simplicity: only one transistor and a capacitor are required per bit, compared to four transistors in SRAM. This allows DRAM to reach very high density. Also DRAM is also cheaper than SRAM.


Can structures be passed to the functions by value?

Structures can be passed to the functions by value. But it has to be copied to another location. Hence wastage of memory
