1 The processor puts the required addresses on to the address bus 2 Any addresses that invoke chip select are decoded 3 Chip select is generated 4 The processor waits for memory to settle 5 The processor generates a memory write control bit (MEMW) 6 The processor puts the data on to the data bus 7 The contents are written to a specific location on memory.

8088 processor accessed 1MB
32 bit processor can access 4294967296 bit memory adderss.
The processor registers! Relatively, they are very small (a register on an Intel 32-bit processor is only 4 bytes large!) but they are very fast. Programs use them to store the part of data they are working on and some memory addresses.
The 8086/8088 processor is a 16 bit processor. In a 16 bit two's complement notation, the maximum number is 0x7FFF, or 32767, while the minimum number is 0x8000, or -32768.
An "Intel-based iMac G5" would be an oxymoron. The "G5" part of it's name refers to having a PowerPC processor.
A 32-bit system has a maximum 2^32 unique memory addresses, which is 4,294,967,296 addresses in total. Each address refers to a byte (the smallest unit of storage), thus this allows a maximum address space of 4 gigabytes. Each additional bit doubles the number of available addresses, thus a 64-bit system supports a maximum of 18,446,744,073,709,551,616 bytes, which is more memory than exists on the planet. Note that the length of a byte is system-defined.
Max. memory address space= 216 X 2 bytes = 128 Kbytes
The requirements for running Mac OS X Leopard are: ▪ Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor ▪ 512MB of memory ▪ DVD drive for installation ▪ 9GB of available disk space
