What is the address of the last byte in a 512 mega byte memory expressed as a decimal number?
The address of the last byte in a 512 mega byte memory, expressed as a decimal number, is 536,870,911.
What is the last address of 128 byte memory?
127
What is the memory address of the last byte of a 1GB memory?
In a 1GB memory space, the total number of bytes is (1 \times 2^{30} = 1,073,741,824) bytes. Since memory addresses typically start at 0, the memory address of the last byte would be (1,073,741,824 - 1 = 1,073,741,823). Therefore, the memory address of the last byte of a 1GB memory is 1,073,741,823.
How do you calculate starting address in the memory map of a 4k byte memory is 2000Hspecify the last address?
If a 4k segment is stored at address 2000H, the last address will be 2FFFH.
The memory address of last location of an 8K byte memory chip is FFFFH. Find the starting address. Will someone Please tell how it is calculated?
The starting address of an 8K byte memory chip that ends at FFFFH is E000H. 8K is 8192 (8 * 1024) which is 2000H. Subtract 2000H from FFFFH, and add 1, and you get E000H.
Is each byte in memory limited in size?
The true answer is yes and no Yes: in binary coded decimal and hexadecimal each byte is 4 bits long; in octal each byte is three bits long. No: in true binary theoretically there is no "last bit".
What is the use of little endian and big endian?
"Little Endian" means that the lower-order byte of the number is stored in memory at the lowest address, and the high-order byte at the highest address. For example, a 4 byte Integer Byte3 Byte2 Byte1 Byte0 will be arranged in memory as follows: Base Address+0 Byte0 Base Address+1 Byte1 Base Address+2 Byte2 Base Address+3 Byte3 Intel processors (those used in PC's) use "Little Endian" byte order. "Big Endian" means that the high-order byte of the number is stored in memory at the lowest address, and the low-order byte at the highest address. The same 4 byte integer would be stored as: Base Address+0 Byte3 Base Address+1 Byte2 Base Address+2 Byte1 Base Address+3 Byte0 Motorola processors (those used in Mac's) use "Big Endian" byte order.
How do you get the Broadcast address of an IP address?
The address before the next valid network address will be the broadcast address For Example:192.168.1.64 the broadcast address is 192.168.1.127
How long is a MAC address and how is it written?
A MAC address is a six-byte unique identifier for any piece of network equipment. The first three bytes are the manufacturer's code and the last three are a serial number within that manufacturer.

Why do pointer occupy only 2 bytes of memory in 16 bit DOS environment?
You've answered your own question, I'm afraid. A 16-bit memory address requires 2 bytes of storage (8 bits * 2 bytes = 16 bits). Note that, without using XMS or EMS, you can only address 2^20 bytes of memory, with the last 384k or so being restricted (BIOS, video, etc) unless you enable the A20 line (it actually wraps from FFFF:0010 back to 0000:0000). Also, you should note that 16-bit pointers work because of a "segment:offset" feature; your current "data segment" determines where in memory your pointer actually points to. If you need a 4-byte pointer, use a far pointerinstead; these pointers can reference any point in memory (up to the aforementioned 1MB limit).
How much time does a bird's memory last?
actually, a bird memory can last up to 2 years...a bird has a very good memory and it can last even longer if it has been trained :)
