Cloud Computing Advantages and Network Models Quiz

Which of the following is a disadvantage of storing data using cloud computing?

In this model of a network, what is the minimum number of nodes that can stop working before the sender and the receiver can't communicate?

In the network model described, what is the maximum number of nodes that can fail and still allow Sender and Receiver to communicate?

Which of the following is NOT an existing vulnerability of the Internet, according to experts?

Which of the following CAN be expressed using one bit?

How many unique products can a 9-bit binary sequence identify?

If the company switches to 10-bit binary sequences, how many more unique products can be identified compared to using 9-bit sequences?

In the program using 4 bits to represent whole numbers, what is the largest whole number that can be represented without overflow?

What is the most likely reason for the overflow error when adding 9 and 7 in the 4-bit program?

Which of the following is a possible explanation for the lower image quality of the saved movie file compared to the original?

Disadvantages of Cloud Computing

Potential data security and privacy concerns due to storing data off-site
Dependence on internet connection for data access
Risk of service outages impacting availability

Network Communication Reliability

Minimum number of nodes that can fail before communication ceases depends on network topology but typically is at least one node in a simple model.
Maximum nodes that can fail while maintaining communication varies by topology, often described by fault tolerance metrics.

Internet Vulnerabilities

Existing vulnerabilities include malware attacks, phishing, and DDoS attacks.
Not all perceived vulnerabilities are classified by experts, such as personal negligence or user error.

Data Representation with Bits

One bit can express two values: binary 0 or 1.
A 9-bit binary sequence can uniquely identify 512 products (2^9).

Binary Sequence Comparison

Switching to 10-bit binary sequences allows identification of 1,024 products (2^10).
This change results in 512 additional unique products identified compared to 9-bit sequences.

Number Representation and Overflow

In a 4-bit program, the largest whole number representable without overflow is 15 (binary 1111).
Overflow can occur in a 4-bit representation when the sum exceeds 15; adding 9 and 7 equals 16, which cannot be accommodated.

Movie File Quality

Lower image quality of a saved movie file may be attributed to compression algorithms reducing file size and sacrificing detail.
