Figure 1: An image — an array or a matrix of pixels arranged in columns and rows.
In a (8-bit) greyscale image each picture element has an assigned intensity that
ranges from 0 to 255. A grey scale image is what people normally call a black and
white image, but the name emphasizes that such an image will also include many
shades of grey.
Figure 2: Each pixel has a value from 0 (black) to 255 (white). The possible range of the pixel
values depend on the colour depth of the image, here 8 bit = 256 tones or greyscales.
A normal greyscale image has 8 bit colour depth = 256 greyscales. A “true colour”
image has 24 bit colour depth = 8 x 8 x 8 bits = 256 x 256 x 256 colours = ~16
million colours.

Answer:
Agentless NAC
Explanation:
An active directory is a kind of storage service that holds data of objects like user credentials, resource location etc, for permission and network access authentication.
Network access control is a form of computer network security that integrates security technology like antivirus, intrusion detection and prevention systems etc to system authorisation and authentication processes to control access to a network.
An agentless network access control uses the active directory to scan devices to confirm its compliance to security policies.
