Answer:

V44 uses Lempel-Ziv-Welch encoding to compress data.

Explanation:

Lempel–Ziv (LZW) created by Abraham Lempel and Jacob Ziv is a universal lossless data compression algorithm. It is an improvement of LZW algorithm.

It makes use of LZ78 algorithms. This algorithm achieve its compression by taking out repeated occurrences of data with references to a dictionary that is built based on the data stream it received as input.

Also, its dictionary pre-initialized with all available possible characters and symbols.

C. control unit.

Explanation:

A processor is a miniaturized central processing unit a in digital system that interconnects and controls the activities of other components in the device.

The components of a microprocessor are the bus, registers, cache memory, arithmetic and logical unit and the central or control unit.

The bus is the transportation medium for all activities in the processor. The registers like the accumulator and the B register are memory locations used to hold the operand of an operation.The cache memory holds data meant for immediate use by the processor. Arithmetic and logical unit carries out the various arithmetic and logical operation in the processor, while the control unit is responsible for handling or managing all activities in the processor.

Lina20 [59]

Answer:

# the number of pizza is initialised

# to 5

number_of_pizza = 5

# number of slice in each pizza

# is initialised to 8

slice_in_each_pizza = 8

# total number of pizza is calculated

total_number_of_slices = number_of_pizza * slice_in_each_pizza

# number of guest who respond yes

# is initialised to 10

number_of_guest_respond_yes = 10

# additional 3 guest is added to existing guest

number_of_guest_respond_yes += 3

# number of left over slice is gotten by using modulo arithmetic

number_of_left_over_slice = total_number_of_slices % number_of_guest_respond_yes

# the number of left over slice

# is printed which is 1

print(number_of_left_over_slice)

Explanation:

Missing Question Part: Use a variable to store the number of pizzas ordered as 5.

Assuming there are 8 slices in each pizza, use a variable to store the total number of slices calculated using the number of pizzas ordered.

Use another variable to store the number of guests who had responded YES as 10.

Three more people responded YES. Update the corresponding variable using an appropriate expression.

Based on the guest count, set up an expression to determine the number of left-over slices if the slices would be evenly distributed among the guests. Store the result of the expression in a variable.

The program is written in Python and it is well commented.
