What is the maximum memory address space that the processor can access directly if it is connected to a 16 bit memory considering a hypothetical microprocessor generating a 16-bit address?

If you assume that it has a 16-bit data bus, then it would be 128k so the microprocessor can access 2^16 points, which is 64k (from it being a 16bit address) 16bits = 2 bytes (memory) so through a 16 bit memory, it can access 2*64k, which is 128k alternatively, if its 8bit memory, 8bits=1byte 1*64k = 64k I'm no expert, and i was searching for the answer myself, hope this helped

Why 16bit is better than 8bit in audio?

When referring to bits, we are discussing digital audio. 16 bits is a sampling or playback rate. This is analogous to a film playing back at 16 frames per second versus 8 frames per second. Therefore you have more resolution, or detail. ---- Update: Actually, the above is not really correct: the number of bits (8, 16, 24...) refer to the sample quantization, the resolution/size of each sample. A sample represents the amplitude of the sound at a given moment, with 8bits you can only represent 256 levels, whereas 16bits gives you 66536 levels, that is better resolution per sample (just like the difference on an image with 256 colors, 8bits, versus 66536 colors, 16bits... or then also 'truecolor'/16Million colors for 24bits). On the other hand, the sampling rate is measured in hertz and specifies the number of samples per second, with common values being 11, 22, 44 Khz (thousand hertz). Sample size (bits) and sample rate (hertz) are the two parameters that determine the quality of audio... and the bigger the better.

Why 8086 requires address bus of 20 bits while using 16 bit address for segement register?

This is due to the fact that 16bits would only address 64KB of memory, which even then was very little. The answer for this was to come up with an extra 4 bits to address the total 1MB, this is done trough segmentation of the memory. Google it.

How many kilobyte is 2000 bytes?

1024 bytes the actual number of bytes in one kilobyte. 2048 is typically referred to as 2 Kilobytes but that is kind of a shorthand. So, technically 2000 bytes exactly would be 1.9531 Kilobytes in the computer world anyway. It all has to do with the binary number system where 2048 is represented with 16bits as 0000100000000000. Each bit from the right to the left is worth double the value of the right most bit that is worth a decimal value of 1. So, again from right to left the bit values are 1,2,4,8,16,32,64,128,256,512,1024,2048. For example the decimal value of 2047 would look like this in binary 00000111111111111. Just add the values of each bit from right to left and you'll get it.

Why 4 bit address bus is grounded?

The data bus in the 8086 is 16 bits in size, while the address bus is 20 (16bits would only address 64KB of memory, an extra 4 bits allows to address the total of 1MB, this is done trough segmentation of the memory). To form a multiplexed of data bus and address bus, four bits of 8086 address bus are grounded.

How many Terabytes of memory would a 40 bit address bus be able to address if the system word length was 8bits 16bits 32bits?

1TB is 240 bytes. It follows that a 40 bit address bus can address 1TB. Since 1TB is 1TB regardless of the system's word size, a 40 bit address bus can address 1TB on a computer with an 8 bit, a 16 bit, a 32 bit, or any other word size.

What would be the size memory size of an image if the image is of 3 Megapixels each pixel is of 16 bits?

A digital image in uncompressed format for exactly 3 mega pixels at a color depth of 16bits would take about 6 megabytes of space. The closest typical dimensions to a 3 megapixel image would be 2048x1536 which is exactly 3,145,728 pixels. Most digital cameras will work at 24 bit color depth so an image of 2048x1536 in lossless uncompressed format would take about 9.45 megabytes of space however most cameras will be able to compress this image using jpeg to less than half that size at very high quality settings and maybe to 1/10th (less than 1 megabyte) at good quality settings.

What is instruction format in computer architecture?

The connection between the hardware and software components of a computer creates the computer architecture. It is basically how the components are connected to form a complete system. Sir Frederick P. Brooks and Sir Lyle R. Johnson presented the idea of computer architecture in 1959. A set of operating codes, operands, an opcode, and an addressing mode make an instruction. The instruction format is the standard instruction format that is directly used by the CPU. The instruction format is just the sequence of bits (0,1). The group of these bits is called a field. Each field of the system provides specific information for a particular task to the CPU about the instruction's operation and the instruction's data. The most fundamental difficulty in format design is instruction length. The longer the command will, take longer the time to fetch it. The types of Fields are discussed below: Operation Field: It specifies the operations that are performed by the instructions like, ADD, SUB, etc. It can be any value or number on which the task has been performed. Operation field is mandatory for every instructor Address Field: It specifies the address of the operand. It refers to the address where the operand is stored. On the basis of multiple address fields, the instruction is categorised as follows: Zero address instruction: The operand positions are implicitly represented in zero address instructions. The stack-organized computer system supports these commands. One address instruction: This instruction manipulates data with the help of an implicit accumulator. Accumulator is a register that performs a logical process for the CPU. It uses one address field. Two address instructions: This address instruction is mostly used. This address command format has three operand fields. In the two address sections, registers or memory addresses can be used. Three address instructions: A three-address command must contain three operand components in its format. These three fields could be registers or memory locations. The instruction pipeline in computer architecture The instruction pipeline in computer architecture shows the system's instruction flow. It has 4 major segments, which are discussed below. Segment 1: The instruction fetch part can be performed using first in, first out (FIFO) buffers. Segment 2: The second section decodes the memory-fetched command before the effective location is computed in a different arithmetic circuit. Segment 3: The input is fetched from memory. Segment 4: The execution of the instructions is performed. Some of the features of instruction are : Addressing model: This is the first part of the instruction format. Data over the instruction format can be represented as an addressing format, and data is stored in the computer's memory or in the CPU's register OPCODE(operation code): This is the second part of the instruction format, and the opcode instructs the processor to perform the desired operation. Operand: Depending upon the processor instruction format, it contains zero to three operands, and this part specifies the data or points to the address of the data.
