Answer:

16 RAM chips

Explanation:

To calculate the number of RAM chips needed, we divide the total size of the main memory by the size of each RAM chip. Hence:

Number of RAM chips required = Main memory size / size of one RAM

2M = 2²¹, 16 = 2⁴, 256K = 2¹⁸, 8 = 2³

Hence:

Number of RAM chips required = (2²¹ * 2⁴) / (2¹⁸ * 2³) = 2⁴ = 16

Therefore 16 RAM chips are necessary

Write a pyhton program to calculate area of a circle?
marta [7]

Answer:

The code to calculate the area of a circle is:

from math import pi

def circleArea(radius):

 if radius > 0:

   return pi * (radius ** 2)

 else:

   return None

if __name__ == '__main__':

 radius = 5

 print("Radius: {} Area: {}".format(radius,circleArea(radius)))

Explanation:

A detailed explanation of each line of code is given below.

#Define the number pi used to calculate the area

from math import pi

#We define a function that calculates the area of a circle

def circleArea(radius):

#Check if the radius is valid ( radius > 0) since there aren´t negative radius

 if radius > 0:

#Compute the area formula for a circle \pi * radius^{2}

   return pi * (radius ** 2)

 else:

#Return None if the radius is invalid

   return None

#Run the function we´ve defined

if __name__ == '__main__':

#Define a radius

 radius = 5

#Call the function and parse the radius through it, then print the result

 print("Radius: {} Area: {}".format(radius,circleArea(radius)))

How to get a javascript's varible
Kamila [148]

Answer:

If you want to use a js variable in a php script you MUST pass it within a HTTP request. There are basically two ways: Submitting or reloading the page.

In programming, just like in algebra, we use variables in expressions (total = price1 + price2). From the example above, you can calculate the total to be 11. JavaScript variables are containers for storing data values. All JavaScript variables must be identified with unique names. These unique names are called identifiers.

What is PCM system? essay
brilliants [131]

A PCM system consists of a PCM encoder (transmitter) and a PCM decoder (receiver). The essential operations in the PCM transmitter are sampling, quantizing and encoding. All the operations are usually performed in the same circuit called as analog-to digital convert Early electrical communications started to sample signals in order to multiplex samples from multiple telegraphy sources and to convey them over a single telegraph cable. The American inventor Moses G. Farmer conveyed telegraph time-division multiplexing (TDM) as early as 1853. Electrical engineer W. M. Miner, in 1903, used an electro-mechanical commutator for time-division multiplexing multiple telegraph signals; he also applied this technology to telephony.
