What is the highest address possible if 16 bits are used for each address?
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 maximum value for a 16-bit number?
65,536
What does 16-bit address bus mean?
Microprocessor and Memory Basics In many older computers, the address bus was 16 bits wide (a = 16). This meant that there were 16 wires. Such microprocessors could address up to 216 = 65536 memory locations. By increasing the width of the address bus, more memory locations can be directly addressed.
How many address locations are possible if size of address bus is 16-bit?
For example, a system with a 16-bit address bus can address 2^16 memory locations. If each memory location holds one byte (8 bits), the addressable memory space is 644 KB of memory.
What is the last address for a 16 bit address bus?
One address addresses one byte. Using 16 bits, you can write 65536 addresses (from 0 to 65535, that’s 65536 different addresses), and address 65536 bytes. 65536 bytes is 64kB.
Can a JPEG be 16 bit?
However, you need to know that saving as a JPEG will convert the file from 16 bit down to 8 bit (as the JPEG file format does not support 16 bit). Note: it is also important to note if you’re saving a layered file as a JPEG, Photoshop will flatten the file as the JPEG file format does not support layers.
How do I make an image 16 bit?
Pull down the “Color Mode” menu and select “RGB Color.” Pull down the “Bit Mode” menu next to it and select “16 bit.” Notice this makes the number in the “Image Size” section of the window much larger. Click “OK” and the Photoshop window opens.
What is 16 bit color depth?
Using two bytes per pixel in a color image. Up to 65,536 colors can be represented in the color palette. Most graphics formats provide 8-bit color or 24-bit color; however, graphics cards generally have an intermediate 16-bit color range that displays 65,536 colors.
Does PNG support 16 bit?
As with RGB and gray+alpha, PNG supports 8 and 16 bits per sample for RGBA or 32 and 64 bits per pixel, respectively. Pixels are always stored in RGBA order, and the alpha channel is not premultiplied.
Does a PNG support transparency?
Transparency. The GIF and PNG formats also both support transparency. If you need any level of transparency in your image, you must use either a GIF or a PNG. If we save the image as a GIF, we can use a transparent background color.
Does PNG have Alpha?
PNG does not use premultiplied alpha.) Transparency control is also possible without the storage cost of a full alpha channel. In an indexed-color image, an alpha value can be defined for each palette entry. Viewers can support transparency control partially, or not at all.
