What will be the address space in the system with 16-bit addresses?
On a 16-bit system, the address bus was 24 bits wide, for a physical address space of 16 Mbytes. On a 32-bit system, the address bus was also 32 bits wide, for a physical address space of 4 Gbytes.
How many bits are needed to represent an address space?
Answers 1: We use binary number systems to represent the address space, so the address space is equal to 2 (number of bits used). So the specific address spaces will be: a. 2 8 = 256 ,From 0 to 255 b. 2 16 =65536 , From 0 to 65535 c.
What is address space give an example?
A computer’s address space is the total amount of memory that can be addressed by the computer. The term may refer to the physical memory (RAM chips) or virtual memory (disk/SSD). For example, a 32-bit computer can address 4GB of physical memory and as much as 64TB of virtual memory.
How is address space calculated?
Here are the requirements:
- 64 KB total memory.
- The first 16 bytes of the address space (starting at the address 0x0000) is reserved for special function registers (IE1, IE2, IFG1, IFG2, etc.)
- The next 240 bytes is reserved for 8-bit peripheral devices.
- The next 256 bytes is reserved for 16-bit peripheral devices.
What will happen if your address space size is bigger than your physical memory?
When a virtual address space is larger than the physical memory, OS can use swapping to evict page frames (e.g. LRU eviction). CPU generates Page Fault where then page that is in disk is swapped into the main memory.
How many address locations are possible if size of address bus is 16-bit?
A 16-bit integer can store 216 (or 65,536) distinct values. In an unsigned representation, these values are the integers between 0 and 65,535; using two’s complement, possible values range from −32,768 to 32,767. Hence, a processor with 16-bit memory addresses can directly access 64 KB of byte-addressable memory.
What is the highest address written in binary?
65536 is the highest address possible if 16 bits are used for each address.
How many address bits are required for a 2048 bit memory?
It means that a memory of 2048 words, where each word is 4 bits. So to address 2048 (or 2K, where K means 2^10 or 1024), you need 11 bits, so 11 address lines.
How many types of address space are there?
The three types of address spaces are the ACB address space, the associated address space, and the session address space.
What is concept of address space?
The range of virtual addresses that the operating system assigns to a user or separately running program is called an address space. This is the area of contiguous virtual addresses available for executing instructions and storing data.
How do you determine the size of a virtual address space?
To increase the size of user space, use BCDEdit /set increaseuserva. In 64-bit Windows, the theoretical amount of virtual address space is 2^64 bytes (16 exabytes), but only a small portion of the 16-exabyte range is actually used.
What is virtual address space size?
The virtual address space for a process is the set of virtual memory addresses that it can use. The virtual address space for 32-bit Windows is 4 gigabytes (GB) in size and divided into two partitions: one for use by the process and the other reserved for use by the system.
