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?

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?
Start Address: Unanswered
(0, 0000, 0x0000)
(FFF, OFFF, 0x0FFF, $0FFF, 4095)
End Address: Unanswered
