Answers

Answer:

False

Explanation:

Both CSS (Cascading Style Sheets) and HTML (Hypertext Markup Language) have online documentation. CSS and HTML are separate languages with different purposes. HTML is used for structuring and presenting content on the web, while CSS is used for styling and formatting the appearance of that content.

Both languages have their own specifications and documentation available online. HTML documentation provides information about the various elements, attributes, and their usage, while CSS documentation covers properties, selectors, and how to apply styles to HTML elements.

Therefore, it is incorrect to say that only CSS has online documentation. Both CSS and HTML have extensive documentation available for reference.

A number is a palindrome if its reversal is the same as itself. Write a program ReverseNumber.java to do the following:
1. Define a method call reverse, which takes a 4-digit integer and returns an integer in reverse. For example, reverse(1234) should return 4321. (Hint: use / and % operator to separate the digits, not String functions)
2. In the main, take user input of a series of numbers, call reverse method each time and then determine if the number is a palindrome number, for example, 1221 is a palindrome number, but 1234 is not.
3. Enhance reverse method to work with any number, not just 4-digit number.

Answers

The reverse method takes an integer as input and reverses it by extracting the last digit using the modulus operator % and adding it to the reversed number after multiplying it by 10.

       int reversedNumber = 0;

Compare and contrast predictive analytics with prescriptive and descriptive analytics. Use examples.

Answers

Explanation:

Predictive, prescriptive, and descriptive analytics are three key approaches to data analysis that help organizations make data-driven decisions. Each serves a different purpose in transforming raw data into actionable insights.

1. Descriptive Analytics:

Descriptive analytics aims to summarize and interpret historical data to understand past events, trends, or behaviors. It involves the use of basic data aggregation and mining techniques like mean, median, mode, frequency distribution, and data visualization tools such as pie charts, bar graphs, and heatmaps. The primary goal is to condense large datasets into comprehensible information.

Example: A retail company analyzing its sales data from the previous year to identify seasonal trends, top-selling products, and customer preferences. This analysis helps them understand the past performance of the business and guide future planning.

2. Predictive Analytics:

Predictive analytics focuses on using historical data to forecast future events, trends, or outcomes. It leverages machine learning algorithms, statistical modeling, and data mining techniques to identify patterns and correlations that might not be evident to humans. The objective is to estimate the probability of future occurrences based on past data.

Example: A bank using predictive analytics to assess the creditworthiness of customers applying for loans. It evaluates the applicants' past financial data, such as credit history, income, and debt-to-income ratio, to predict the likelihood of loan repayment or default.

3. Prescriptive Analytics:

Prescriptive analytics goes a step further by suggesting optimal actions or decisions to address the potential future events identified by predictive analytics. It integrates optimization techniques, simulation models, and decision theory to help organizations make better decisions in complex situations.

Example: A logistics company using prescriptive analytics to optimize route planning for its delivery truck fleet. Based on factors such as traffic patterns, weather conditions, and delivery deadlines, the algorithm recommends the best routes to minimize fuel consumption, time, and cost.

In summary, descriptive analytics helps organizations understand past events, predictive analytics forecasts the likelihood of future events, and prescriptive analytics suggests optimal actions to take based on these predictions. While descriptive analytics forms the foundation for understanding data, predictive and prescriptive analytics enable organizations to make proactive, data-driven decisions to optimize their operations and reach their goals.

Question 3 3.1 Describe the TWO main elements of a CPU 3.2 Describe the fetch/execute cycle 3.3 Convert the binary number 00000011 to a decimal ​

Answers

Answer:

Here are the answers to the questions:

3.1 The two main elements of a CPU are:

The Control Unit (CU): The CU controls and coordinates the operations of the CPU. It is responsible for interpreting instructions and sequencing them for execution.

The Arithmetic Logic Unit (ALU): The ALU executes arithmetic and logical operations like addition, subtraction, AND, OR, etc. It contains registers that hold operands and results.

3.2 The fetch/execute cycle refers to the cycle of events where the CPU fetches instructions from memory, decodes them, and then executes them. The steps in the cycle are:

Fetch: The next instruction is fetched from memory.

Decode: The instruction is decoded to determine what it is asking the CPU to do.

Execute: The CPU executes the instruction. This could involve accessing data, performing calculations, storing results, etc.

Go back to Fetch: The cycle continues as the next instruction is fetched.

3.3 The binary number 00000011 is equal to the decimal number 3.

Binary: 00000011

Decimal: 1 + 2 = 3

So the conversion of the binary number 00000011 to decimal is 3.

Hint: if your roll no is 33 then your ip address will look like this: 33.33.33.33/20

Answers

Answer:

If there’s one topic that trips people up (both new and experienced) in the networking industry, it is that of Subnetting.

One of the reasons this happens is that one has to perform (mental) calculations in decimal and also binary. Another reason is that many people have not had enough practice with subnetting.

In this article, we will discuss what Subnetting is, why it came about, its usefulness, and how to do subnetting the proper way. To make this article as practical as possible, we will go through many examples.

Note: While subnetting applies to both IPv4 and IPv6, this article will only focus on IPv4. The same concepts explained here can be applied to IPv6. Moreover, subnetting in IPv6 is more of a want rather than a necessity because of the large address space.

IP address network

For example, any traffic with a destination IP address of 192.168.1.101 will be delivered to PC1, while traffic addressed to 192.168.1.250 will be delivered to SERVER.

Note: This is an oversimplification of things just for understanding sake and refers to Unicast (one-to-one) IPv4 addresses. Traffic sent to Multicast (one-to-many) and Broadcast (one-to-all) IP addresses can be delivered to multiple devices. Also, features like Network Address Translation (NAT) allow one IP address to be shared by multiple devices.

To help your understanding of IP addresses and subnetting, you need to resolve the following fact in your head: Computers think in binary, that is, 0s and 1s. Therefore, even though we see an IP address represented like 192.168.1.250, it is actually just a string of bits – 32 bits in total for IPv4 addresses.

To make them more readable for humans, IPv4 addresses are represented in dotted decimal notation where the 32 bits are divided into 4 blocks of 8 bits (also known as an octet), and each block is converted to a decimal number.

For example, 01110100 in binary is 116 in decimal:

A unicast IPv4 address such as 192.168.1.250 can be divided into two parts: Network portion and Host ID. So what does this mean? Well, IPv4 addresses were originally designed based on classes: Class A to Class E. Multicast addresses are assigned from the Class D range while Class E is reserved for experimental use, leaving us with Class A to C:

Class A: Uses the first 8 bits for the Network portion leaving 24 bits for host IDs. The leftmost bit is set to “0”.

Class B: Uses the first 16 bits for the Network portion leaving 16 bits for host IDs. The two leftmost bits are set to “10”.

Class C: Uses the first 24 bits for the Network portion leaving 8 bits for host IDs. The three leftmost bits are set to “110”.

Note: The range of Class A is actually 1-126 because 0.x.x.x and 127.x.x.x are reserved.

With these classes, a computer/device can look at the first three bits of any IP address and determine what class it belongs to. For example, the 192.168.1.250 IP address clearly falls into the Class C range.

Looking at the Host ID portion of the classes, we can determine how many hosts (or number of individual IP addresses) a network in each class will support. For example, a Class C network will ideally support up to 256 host IDs i.e. from 00000000 (decimal 0) to 11111111 (decimal 255). However, two of these addresses cannot be assigned to hosts because the first (all 0s) represents the network address while the last (all 1s) represents the broadcast address. This leaves us with 254 host IDs. A simple formula to calculate the number of hosts supported

Explanation: Final answer is Start address: 192.168.58.0 + 1 = 192.168.58.1

End address: 192.168.58.16 – 2 = 192.168.58.14

Broadcast address: 192.168.58.16 – 1 = 192.168.58.15

Assume a 2^20 byte memory:

a) What are the lowest and highest addresses if memory is byte-addressable?

b) What are the lowest and highest addresses if memory is word-addressable, assuming a 16-bit word?

c) What are the lowest and highest addresses if memory is word-addressable, assuming a 32-bit word?

a) Lowest address: 0, Highest address: (2^20) - 1. b) Lowest address: 0, Highest address: ((2^20) / 2) - 1. c) Lowest address: 0, Highest address: ((2^20) / 4) - 1.

a) If memory is byte-addressable, the lowest address would be 0 and the highest address would be (2^20) - 1.

This is because each byte in the memory requires a unique address, and since there are 2^20 bytes in total, the highest address would be one less than the total number of bytes.

b) If memory is word-addressable with a 16-bit word, each word would consist of 2 bytes.

Therefore, the lowest address would be 0 (representing the first word), and the highest address would be ((2^20) / 2) - 1.

This is because the total number of words is equal to the total number of bytes divided by 2.

Subtracting 1 gives us the highest address, as the addresses are zero-based.

c) If memory is word-addressable with a 32-bit word, each word would consist of 4 bytes.

In this case, the lowest address would still be 0 (representing the first word), and the highest address would be ((2^20) / 4) - 1.

Similar to the previous case, the total number of words is equal to the total number of bytes divided by 4.

Subtracting 1 gives us the highest address.

a.) Software architecture is the set of principal design decisions about a system. b.) Software architecture dictates the process used by a team to develop use cases for a software system c.) Software architecture serves as the blueprint for construction and evolution of a software system d.) Software architecture is the clear definition of multiple high-level components that, when working together, form your system and solve your problem e.) All of the above statements are true.

Answers

Question:

Which of the following statements is not a true statement about software architecture?

Answer:

b.) Software architecture dictates the process used by a team to develop use cases for a software system.

Explanation:

A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are six (6) main stages in the creation of a software and these are;

1. Planning.

2. Analysis.

3. Design.

4. Development (coding).

5. Deployment.

6. Maintenance.

One of the most important steps in the software development life cycle (SDLC) is design. It is the third step of SDLC and comes immediately after the analysis stage.

Basically, method design is the stage where the software developer describes the features, architecture and functions of the proposed solution in accordance with a standard.

Software architecture can be defined as the software blueprint or infrastructure in which the components (elements) of the software providing user functionality and their relationships are defined, deployed and executed. Thus, it is a structured framework used by software developers to model software components (elements), properties and relationships in order to have a good understanding of how the program would behave.

In conclusion, software architecture doesn't dictate the process used by a team to develop use cases for a software system.

Which statement most aptly defines the term networking?

A backup operator wants to perform a backup to enhance the RTO and RPO in a highly time- and storage-efficient way that has no impact on production systems. Which of the following backup types should the operator use?
A. Tape
B. Full
C. Image
D. Snapshot

Answers

In this scenario, the backup operator should consider using the option D-"Snapshot" backup type.

A snapshot backup captures the state and data of a system or storage device at a specific point in time, without interrupting or impacting the production systems.

Snapshots are highly time- and storage-efficient because they only store the changes made since the last snapshot, rather than creating a complete copy of all data.

This significantly reduces the amount of storage space required and minimizes the backup window.

Moreover, snapshots provide an enhanced Recovery Time Objective (RTO) and Recovery Point Objective (RPO) as they can be quickly restored to the exact point in time when the snapshot was taken.

This allows for efficient recovery in case of data loss or system failure, ensuring minimal downtime and data loss.

Therefore, to achieve a highly time- and storage-efficient backup solution with no impact on production systems, the backup operator should utilize the "Snapshot" backup type.

What feature allows a person to key on the new lines without tapping the return or enter key

Answers

The feature that allows a person to key on new lines without tapping the return or enter key is called word wrap

How to determine the feature

When the current line is full with text, word wrap automatically shifts the pointer to a new line, removing the need to manually press the return or enter key.

In apps like word processors, text editors, and messaging services, it makes sure that text flows naturally within the available space.

This function allows for continued typing without the interruption of line breaks, which is very helpful when writing large paragraphs or dealing with a little amount of screen space.
