# Question: How Do You Calculate Address Line?

## How many address lines are required for 1mb memory?

20“20” address lines or address bus are required to span “1MB” memory space.

Because 1MB is equal to bytes..

## What is the size of a memory address?

32 bitsMemory addresses are numbers too, so on a 32-bit CPU the memory address consists of 32 bits. It works exactly like usual addition, but the maximum digit is 1, not 9. Decimal 0 is 0000 , then you add 1 and get 0001 , add one once again and you have 0010 .

## What is address line and data line?

The Bus (2) Buses consist of data lines, control lines, and address lines. While the data lines convey bits from one device to another, control lines determine the direction of data flow, and when each device can access the bus. Address lines determine the location of the source or destination of the data.

## How do I find the address bus size?

So to work out the amount of addressable memory, we must multiply the number of addresses by their size.Total Addressable Memory = (2^address bus width) * Data bus width.IE a machine with a 16 bit Data Bus and 32 bit address bus would have.(2^32)*16 bits of accessible storage.or 8GB – Do the math yourself to prove it.

## What are the address lines?

Most written addresses use three lines: Recipient. Building/residence address. City, state, and zip code.

## How do you calculate address and data line?

An address line usually refers to a physical connection between a CPU/chipset and memory. They specify which address to access in the memory. So the task is to find out how many bits are required to pass the input number as an address. In your example, the input is 2 kilobytes = 2048 = 2^11, hence the answer 11.

## What are the 3 types of buses?

Three types of bus are used.Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices. … Data bus – carries the data between the processor and other components. … Control bus – carries control signals from the processor to other components.

## What is address bus width?

Microprocessor and Memory Basics a is the width of the address bus, while d is the width of the data bus. In many older computers, the address bus was 16 bits wide (a = 16). … ARM processors normally have 32-bit wide address buses. A 32-bit ARM processor could address up to 232 = 4,294,967,296 memory locations!

## How many bits is my address bus?

36 bitsThe number of bits in address bus is determined by the size of the addressable section of main memory. In modern computers, the address buses are generally of 36 bits. With 36 bits of address bus, theoretically, a main memory of 64 GB can be accessed.

## How many address lines are needed for memory?

Address lines needed to address each memory location – Example – Networking. It means that a memory of 2048 words, where each word is 4 bits. So to address 2048 (or 2K, where K means 2^10 or 1024), you need 11 bits, so 11 address lines.

## How many address lines are required to represent 32k memory?

Ans. 32K = 25 x 210 = 215, Hence 15 address bits are needed; Only 16 bits can address this.
