The type of long-term memory that stores specific instructions for a computer to operate is called ROM (Read-Only Memory). ROM contains firmware, which is the permanent software programmed into the hardware that allows the computer to boot up and perform essential functions. Unlike RAM, ROM retains its data even when the computer is powered off, ensuring that critical instructions are always available.
Yes the CPU is the "brains" behind the computer, while the RAM is its temporary memory.
RAM is used for storing the start-up instructions on the computer. This serves as the memory of the computer which will retrieve such instructions.
execute
A program is a series of instructions that directs a computer how to perform the tasks necessary to process data into information. Programmers write a program and then store the program in a file that a user can execute (run). When a user runs a program, the computer loads the program from a storage medium into memory. Thus, a program is entered into a computer'smemory, as it is needed. Programs respond to commands that a user issues.
Every microprocessor architecture has a specific set of instructions that are embedded into the processor itself and each instruction correspond to a specific opcode. Data and instructions in memory are represented in an address format.
Memory cache stores frequently used instructions and data on a computer. Cache memory is stored on a memory chip in an area of the RAM.

Memory Addresses
A memory address is a specific location in a computer's memory where data is stored. Memory addressability refers to the maximum amount of memory that a computer system can access and use. In other words, memory addressability is the range of memory addresses that a computer can access, while a memory address is a specific location within that range.
A base memory address is the starting point in memory from which a program or process accesses its data and instructions. It serves as a reference point for calculating the locations of various data elements or instructions within memory. In many programming environments, the base address is typically used in conjunction with an offset to access specific memory locations efficiently. This concept is fundamental in memory management and addressing schemes in computer architecture.
RISC architectures generally have fewer instructions that operate directly on memory locations than CISC architectures. So, where a CISC machine will have instructions that operate directly on memory, in RISC this would be implemented as: Load from memory into register, do operation on register, store register back into memory. So a lot of the processing revolves around the Load-Store loop.
