How are the address binding of instructions and data is carried to memory address?

Address binding of instructions and data to memory addresses can happen at three different stages:
Compile time: If memory location known a priori, absolute code can be generated; must recompile code if starting location changes.
Load time: Must generate relocateable code if memory location is not known at compile time.
Execution time: Binding delayed until run time if the process can be moved during its execution from one memory segment to another. Need hardware support for address maps (e.g., base and limit registers).

What is address binding in operating systems?
A program, to be executed, must be brought to main memory. The instructions that use addresses in a program, must be bound to proper address space in main memory. Address binding is a scheme that performs this job. It can be thought as a mapping from one address space to another. There are bindings available as follows: Compile time binding Load time binding Execution time binding
What is logical address space and physical address space?
Logical address is the address generated by the CPU (from the perspective of a program that is running) whereas physical address (or the real address) is the address seen by the memory unit and it allows the data bus to access a particular memory cell in the main memory. All the logical addresses need to be mapped in to physical addresses before they can be used by the MMU. Physical and logical addresses are same when using compile time and load time address binding but they differ when using execution time address binding.
Both computer instructions and memory address are represented by?
Binary Codes
What is load time binding?
: Compiler generates relocatable code if memory location is not known at compile time. Address assigned as loaded; If starting address
Physical address and logical address?
A logical (or virtual) address is a reference to a memory location independent of the current assignment of data to memory; a translation must be made to a physical address before the memory access can be achieved. A relative address is the address expressed as a location relative to some known point, usually the beginning of the program. A physical address, or absolute address, is an actual location in main memory.

What are the four categories of cargo carried over a bus?
Electrical power, Control Signals, Data, and Memory Addresses. (CPU BUS)
What is the memory's addressibility?
HI I am Ahtarva,The addressibility is how many bits does that particular processor or micro-controller's architecture use to specify the address of a memory location in the memory. For example if someone say that addressibility is 8 bit then your memory address contains 8 bits and at maximum you have 2^8 different memory locations (or say memory addresses in your device). Here 2^8 is called Address space.
What is the purpose of an address bus?
The address bus is used by the processor in a computer to locate a piece of data from the RAM (Random Access Memory) that it needs to access. No real data is carried via the address bus, as this is the job of the Data Bus. The pieces of data that the address bus locates are called "addresses" and the address bus transfers "data addresses" to and from the control unit.
What is a cache?
Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory. Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..
What memory holds data and instructions as the CPU processes them?
memory
What is the Difference Between memory address and memory?
Memory is microchip; address are processor board slots
