As you know computer system stores all types of data as stream of binary digits (0 and 1). This also includes the numbers having fractional values, where placement of radix point is also incorporated along with the binary representation of the value. There are different approaches available in the literature to store the numbers having fractional part. One such method, called Floating-point notation is discussed in your week 03 lessons. The floating point representation need to incorporate three things:
• Sign
• Mantissa
• Exponent
A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-
point notation.
B. Determine the smallest (lowest) negative value which can be
incorporated/represented using the 8-bit floating point notation.
C. Determine the largest (highest) positive value which can be
incorporated/represented using the 8- bit floating point notation.
Answers
Answer:
A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-point notation.
First, let's convert -9/2 to a decimal number: -9/2 = -4.5
Now, let's encode -4.5 using the 8-bit floating-point notation. We'll use the following format for 8-bit floating-point representation:
1 bit for the sign (S), 3 bits for the exponent (E), and 4 bits for the mantissa (M): SEEE MMMM
Sign bit: Since the number is negative, the sign bit is 1: 1
Mantissa and exponent: Convert -4.5 into binary and normalize it:
-4.5 in binary is -100.1. Normalize it to get the mantissa and exponent: -1.001 * 2^2
Mantissa (M): 001 (ignoring the leading 1 and taking the next 4 bits)
Exponent (E): To store the exponent (2) in 3 bits with a bias of 3, add the bias to the exponent: 2 + 3 = 5. Now, convert 5 to binary: 101
Now, put the sign, exponent, and mantissa together: 1101 0010
So, the 8-bit floating-point representation of -9/2 (-4.5) is 1101 0010.
B. Determine the smallest (lowest) negative value which can be incorporated/represented using the 8-bit floating-point notation.
To get the smallest negative value, we'll set the sign bit to 1 (negative), use the smallest possible exponent (excluding subnormal numbers), and the smallest mantissa:
Sign bit: 1
Exponent: Smallest exponent is 001 (biased by 3, so the actual exponent is -2)
Mantissa: Smallest mantissa is 0000
The 8-bit representation is 1001 0000. Converting this to decimal:
-1 * 2^{-2} * 1.0000 which is -0.25.
The smallest (lowest) negative value that can be represented using the 8-bit floating-point notation is -0.25.
C. Determine the largest (highest) positive value which can be incorporated/represented using the 8-bit floating-point notation.
To get the largest positive value, we'll set the sign bit to 0 (positive), use the largest possible exponent (excluding infinity), and the largest mantissa:
Sign bit: 0
Exponent: Largest exponent is 110 (biased by 3, so the actual exponent is 3)
Mantissa: Largest mantissa is 1111
The 8-bit representation is 0110 1111. Converting this to decimal:
1 * 2^3 * 1.1111 which is approximately 1 * 8 * 1.9375 = 15.5.
The largest (highest) positive value that can be represented using the 8-bit floating-point notation is 15.5.

4. (15 points) Give an algorithm that takes as input a positive integer n and a number x, and computes xn (i.e., x raised to the power n) by performing O(lgn) multiplications. Your algorithm CANNOT use the exponentiation operation, and may use only the basic arithmetic operations (addition, subtraction, multiplication, division, modulo). Moreover, the total number of basic arithmetic operations used should be O(lgn).
Answers
Answer:
The algorithm is as follows:
Exponent(x, n):
if(n == 0):
return 1
pr = Exponent(x, int(n / 2))
if (n % 2 == 0):
Return pr* pr
else:
if(n > 0):
Return x * pr* pr
else:
Return (pr* pr) / x
Explanation:
In order to get a O(log n) time complexity, a recursive procedure is implemented by the algorithm
The algorithm begins here
Exponent(x, n):
If n is 0, the procedure returns 1
if(n == 0):
return 1
This recursively calculates the product of x, n/2 times
pr= Exponent(x, int(n / 2))
If n is even, the square of prod (above) is calculated
if (n % 2 == 0):
Return pr* pr
If otherwise (i.e. odd)
else:
If n is above 0, the square of prod multiplied by x is calculated
if(n > 0):
Return x * pr* pr
If otherwise, the square of prod divide by x is calculated
else:
Return (\(pr* pr\)) / x
The time complexity is: O(log|n|)

You have been keeping up with the network by configuring the routers statically. However users have had problems with downtime in the past year because of network links going off line, as there's only one route to reach every subnet. The owner wants fault tolerance built into the network to include back up links in case a primary link goes offline. You're concerned that the current router configuration method will still cause some downtime, even if the backup links operate correctly. Why might there be downtime if a primary link goes offline but the backup link is ok? What can you do to reduce the possibility of downtime?
Answers
There may be downtime if a primary link goes offline but the backup link is ok because the router configuration is static, meaning the router will not automatically detect the new backup link and switch to it.

How did early computing device such as Charles Babbage's analytical engine and Ada Lovelace's contributions set the foundation for modern computing
Answers
Early computing devices, such as Charles Babbage's Analytical Engine and Ada Lovelace's contributions, played a crucial role in setting the foundation for modern computing. Here's how their work contributed to computing development:
1. Charles Babbage's Analytical Engine: Babbage designed the Analytical Engine, a mechanical general-purpose computer concept, in the 19th century. Although the Analytical Engine was never fully built, its design and principles laid the groundwork for modern computers. Key features of the analytical engine include:
a. Stored Program: Babbage's Analytical Engine introduced the concept of storing instructions and data in memory, allowing complex calculations and tasks.
b. Control Flow: The Analytical Engine could make decisions and perform conditional operations based on previous computations, resembling the modern concept of control flow in programming.
c. Loops: Babbage's design incorporated looping mechanisms, enabling repetitive instruction execution, similar to modern programming languages.
2. Ada Lovelace's Contributions: Ada Lovelace, an English mathematician, collaborated with Charles Babbage and made significant contributions to computing. Her work on Babbage's Analytical Engine included writing the first algorithm intended for machine implementation. Lovelace realized the potential of the analytical engine beyond numerical calculations and recognized its capability for processing symbols and creating complex algorithms. Her insights laid the foundation for computer programming and algorithms.
Lovelace's ideas about the analytical engine extended beyond what was initially envisioned. He stressed the importance of machines handling more than just numbers. Her contributions demonstrated computers' potential to perform tasks beyond basic calculations and numerical processing.
Collectively, Babbage's analytical engine and Lovelace's contributions provided early conceptual frameworks for modern computing. Their ideas influenced subsequent pioneers in the field, and the concepts they introduced paved the way for the development of the digital computers we use today.
how many ways are there to permute the letters in each of the following words? (a) number (b) discrete (c) subsets
Answers
The permutations for each word are:
(a) number - 8! = 40,320(b) discrete - 8! = 40,320(c) subsets - 6! = 720Understanding Permutations: A Guide to Counting Possible CombinationsPermutations are a powerful tool for calculating the number of possible arrangements of a given set of items. Whether it is a set of letters, numbers, or other objects, understanding how to calculate the number of possible permutations can help to solve a variety of problems. This essay will provide a guide to understanding and calculating permutations, focusing on the three examples given above.
To begin, permutations involve rearranging a set of items in different combinations, or orders. This rearrangement is done without replacement, meaning that each item can only be used once in each permutation. For example, when permuting the letters in the word "number," each letter can only be used once, and it cannot be repeated. To calculate the number of permutations, the formula n! (where n is the number of items in the set) is used. Applying this formula to the three examples given produces the results shown above.
