rgb_scale = 255

cmyk_scale = 100

def rgb_to_cmyk(r,g,b):

if (r == 0) and (g == 0) and (b == 0):

return 0, 0, 0, cmyk_scale

# rgb [0,255] -> cmy [0,1]

c = 1 - r / float(rgb_scale)

m = 1 - g / float(rgb_scale)

y = 1 - b / float(rgb_scale)

min_cmy = min(c, m, y)

c = (c - min_cmy)

m = (m - min_cmy)

y = (y - min_cmy)

k = min_cmy

return c*cmyk_scale, m*cmyk_scale, y*cmyk_scale, k*cmyk_scale

def cmyk_to_rgb(c,m,y,k):

r = rgb_scale*(1.0-(c+k)/float(cmyk_scale))

g = rgb_scale*(1.0-(m+k)/float(cmyk_scale))

b = rgb_scale*(1.0-(y+k)/float(cmyk_scale))

return r,g,b

Chronology can be defined as an arrangement of data, items or documents in the order in which they occurred or happened (in time), from the earliest to the most recent or latest.

Simply stated, ordered events are organized in order of time and this process is known as chronology.

Generally, a chronology can be used as a filing process in various areas such as schools, hospitals, hotels, and business firms to help put data (informations) in order by time or date.

In Computer networking, a cable can be defined as a wired connector used for connecting and transmitting signals between two or more network devices such as CAT-5, CAT-6 and fiber optic cables. These cables which are either twisted or untwisted pair are to be crimped in order to make them eligible and appropriate for use in connecting network devices.

Furthermore, there are two (2) color codes used for the arrangement of the wires in a network cable based on the type of network connection;

I. For straight-through, host device to a router or switch;

Color code: white-orange, orange, white-green, blue, white-blue, green, white-brown, brown.

II. For cross-over, network device to a network device e.g router or router;

white-green, green, white-orange, blue, white-blue, orange,
