LOOP- doing something over and over again until a requirement is met

REPEAT- performing the same tasks again and again

CONDITIONALS- certain requirements

VARIABLE- something that is defined in a piece of code


A PROGRAMMER IS TO A COMPUTER AS A TEACHER IS TO: A student

A GOOD ALGORITHM MUST BE: Efficient and easy to understand

  1. PROGRAM
  2. FUNCTION
  3. STEP

10. IF A PROGRAM HAS GONE THROUGH MANY ITERATIONS, WHAT MUST BE TRUE? A condition(?)

11. What is a benefit of DRYing up code? c. It saves programmers time

Which CIDR network has the smallest possible number of hosts? a. 123.0.0.0/8 b. 123.45.0.0/16 c. 123.45.67.0/24 d. All have the
Lina20 [59]

Answer:

CIDR is based on a variable-length subnet masking technique, which allows a new method of representation for IP addresses. Routing prefix is written with a suffix number of bits of the name, such as 123.0.0.0/8, as the CIDR network has the smallest possible amount of hosts.

Explanation:

CIDR ( Class Inter-Domain Routing ) It is a method that is allocating IP addresses and routing the IP. CIDR is introduced in 1933 and replace the architecture of network design on the internet. CIDR slows down the growth of the routing across the web and helps to slow the IP addresses such as IPv4 addresses.

CIDR consists of two groups of bits in the address. In the new age, the network prefix identifies the whole network. This is used as the basis of routing between IP networks and allocation policies.

IPv4 in-network prefix is 8-bit groups.

A typical IPv4 address is 192.168.0.5 the lowest value is 0, and the highest value is 255

In the given choices, 123.0.0.0 / 8 of the possible smallest number of hosts.

Answer:

D. Change the def to def area (width, height = 12)

Explanation:

Required

Update the function to set height to 12 when height is not passed

To do this, we simply update the def function to:

def area (width, height = 12)

So:

In boxlarea = area (5,2), the area will be calculated as:

area = 5 * 2 = 10

In box2area = area (6), where height is not passed, the area will be calculated as:

area = 6 * 12 = 72
