What is the size of a memory location?
One memory location stores 1 byte (8 bits). The basic storage unit for memory is 1 byte. If you need to store 4 bytes, and place the first byte at 0001, the last byte will be at 0004. That’s one byte at each of 0001, 0002, 0003, and 0004.
How many bytes does the memory contain?
Integers are commonly stored using a word of memory, which is 4 bytes or 32 bits, so integers from 0 up to 4,294,967,295 (232 – 1) can be stored.
How do I find the memory size in Word?
Step 1: calculate the length of the address in bits (n bits) Step 2: calculate the number of memory locations 2^n(bits) Step 3: take the number of memory locations and multiply it by the Byte size of the memory cells.
How much is the capacity of a 2 megabyte memory?
GB to MB Conversion Table
| Gigabytes (GB) | Megabytes (MB) decimal | Megabytes (MB) binary |
|---|---|---|
| 1 GB | 1,000 MB | 1,024 MB |
| 2 GB | 2,000 MB | 2,048 MB |
| 3 GB | 3,000 MB | 3,072 MB |
| 4 GB | 4,000 MB | 4,096 MB |
How do you calculate total memory size?
What is the size of the address bus of a 1 byte memory with 1 byte per memory location?
If each memory location holds one byte (8 bits), the addressable memory space is 644 KB of memory.
What is word in computer memory?
In computing, a word is the natural unit of data used by a particular processor design. The largest possible address size, used to designate a location in memory, is typically a hardware word (here, “hardware word” means the full-sized natural word of the processor, as opposed to any other definition used).
How many m-k bits of the address identify a word in memory?
If the memory size is 2m bytes, then the address size is at least m; that is, m address bits identify a byte in memory; If the word size is w = 2k bytes, then there are 2m/w = 2m/2k = 2m-k words inthe memory;Therefore, m-k bits of the address identify the word in memory;
What is the difference between byte addressable memory & word addressable memory?
Now we can clearly state the difference between Byte Addressable Memory & Word Addressable Memory. When the data space in the cell = 8 bits then the corresponding address space is called as Byte Address. When the data space in the cell = word length of CPU then the corresponding address space is called as Word Address.
How do you calculate the number of memory locations in C?
Step 1: calculate the length of the address in bits (n bits) Step 2: calculate the number of memory locations 2^n(bits) Step 3: take the number of memory locations and multiply it by the Byte size of the memory cells. If each cell was 2 bytes for example, would I multiply 2^n bits (for address length) by the 2 Bytes per memory cell.
Why can’t you have more than one address for memory bytes?
Every byte of memory has its own address, no matter how big the CPU machine word is. Eg. Intel 8086 CPU was 16-bit and it was addressing memory by bytes, so do modern 32-bit and 64-bit CPUs. That’s the cause of the first limit – you can’t have more addresses than memory bytes.
