How many memory locations can be addressed with address bus of 16 bits?

How many memory locations can be addressed with address bus of 16 bits?

For example, a system with a 16-bit address bus can address 2^16 memory locations. If each memory location holds one byte (8 bits), the addressable memory space is 644 KB of memory.

What are 16-bit numbers?

In computer architecture, 16-bit integers, memory addresses, or other data units are those that are 16 bits (2 octets or 2 Bytes) wide. If we consider the signed range of integer values that can be stored in 16 bits is −32,768 (−1 × 215) through 32,767 (215 − 1).

What is the maximum memory address space that the microprocessor can access directly if a 16-bit memory module is interfaced with the microprocessor?

The microprocessor can access 216=65536 memory addresses, regardless of the size of data held at each memory address. If each memory address holds one byte (8 bits) of data then the total memory size that can be addressed directly is 216 bytes, which is 26 KiB=64 KiB.

What is the maximum memory address?

The 1620 used 5-digit decimal addresses, so in theory the highest possible address was 99,999. In practice, the CPU supported 20,000 memory locations, and up to two optional external memory units could be added, each supporting 20,000 addresses, for a total of 60,000 (00000–59999).

What if the data bus is 64 bits wide but instructions are 16 bits long?

The only place that it might make a difference is to the instruction decoder – It would just shift through 16 bits at a time until all 64 bits are processed, and not need another memory access to get more until the 4 instructions are processed…

What is a good amount of RAM?

Most users will only need about 8 GB of RAM, but if you want to use several apps at once, you might need 16 GB or more. If you don’t have enough RAM, your computer will run slowly and apps will lag. Although having enough RAM is important, adding more won’t always give you a substantial improvement.

How much RAM can I possibly?

Matt Ball jumps right in with the theoretical answer: Theoretically: 16.8 million terabytes. In practice: your computer case is a little too small to fit all that RAM.

How much faster is RAM than HDD?

As shown in the graph, the speed of the RAM disk as compared to a Hard disk is typically up to 50 times faster for sequential reads and writes, and up to 200 times faster for small 4KB-size transfers.

Is there a 1 TB RAM?

The 1TB of RAM is very likely an estimate though, as 16GB modules would give you just 768GB of memory. On the other hand, if those modules are actually 32GB sticks, you’d get a mind-boggling 1,536GB of RAM. Either way, the 1TB figure is probably the result of some very loose rounding up.

Is 1 TB RAM overkill?

A: No, 1 TB of RAM is not overkill, if that is what you need to get the job done. I have several clients that have budgeted to get the new MacBook Pro with 1.5 TB of RAM and they are happy to pay for it (it actually can hold 2 TB of RAM but Apple only will preinstall up to 1.5 TB of RAM).
