A computer has been designed using a microprocessor with a 16-bit address bus (A0-A15, where AO is the least significant bit). The 64K address space has been split into sections and allocated to RAM, ROM and I/O hardware. The computer's address space has been divided into five main sections: BIOS ROM, a ROM chip containing the computer's BIOS, two separate blocks of RAM, a block of I/O devices, and a final blo RAM specifically used for the computer's video display. Various logic signals are generated to select the various RAM, ROM or I/O hardware if the address bus contains an address within the range allocated to that device. Note: In the questions below, the operator means logical and, the operation means logical or, while logical not is represented by drawing a line over everything (e.g., A15) The following logic equation is true if the address bus contains an address in the range for the operating system ROM: OSROMCS A15 A14 A13 A12 Giving your answer in hexadecimal, what are the start and end addreses for this block of ROM? Start Address: Unanswered (0, 0000, 0x0000) End Address: Unanswered (FFF, OFFF, 0x0FFF, $0FFF, 4095)

Can someone explain step by step how to do this please the awsners are in the brackets.
![A computer has been designed using a microprocessor with a 16-bit address bus (A0—A15, where AO is the least significant bit). The 64K address space has been split into sections and allocated to
RAM, ROM and I/O hardware.
The computer's address space has been divided into five main sections: BIOS ROM, a ROM chip containing the computer's BIOS, two separate blocks of RAM, a block of I/O devices, and a final block
RAM specifically used for the computer's video display. Various logic signals are generated to select the various RAM, ROM or I/O hardware if the address bus contains an address within the range
allocated to that device.
Note: In the questions below, the operator means logical and, the + operation means logical or, while logical not is represented by drawing a line over everything (e.g., A15)
The following logic equation is true if the address bus contains an address in the range for the operating system ROM:
OSROMCS = A15 A14 A13 • A12
Giving your answer in hexadecimal, what are the start and end addreses for this block of ROM?
