What is the output of the sum of 1001011 and 100011 displayed in hexadecimal?
Answers
Answer:
\(1001011_2\) \(+\) \(100011_2\) \(=\) \(6E_{hex}\)
Explanation:
Required
\(1001011_2 + 100011_2 = []_{16}\)
First, carry out the addition in binary
\(1001011_2\) \(+\) \(100011_2\) \(=\) \(1101110_2\)
The step is as follows (start adding from right to left):
\(1 + 1 = 10\) --- Write 0 carry 1
\(1 + 1 + 1(carry) = 11\) ---- Write 1 carry 1
\(0 + 0 + 1(carry) = 1\) ---- Write 1
\(1 + 0 = 1\) --- Write 1
\(0 + 0 = 0\) ---- Write 0
\(0 + 0 = 0\) ---- Write 0
\(1 + 1 = 10\) --- Write 0 carry 1
No other number to add ; So, write 1 (the last carry)
So, we have:
\(1001011_2\) \(+\) \(100011_2\) \(=\) \(1101110_2\)
Next, convert \(1101110_2\) to base 10 using product rule
\(1101110_2 = 1 * 2^6 +1 * 2^5 + 0 * 2^4 + 1 * 2^3 + 1 * 2^2 + 1 * 2^1 + 0 * 2^0\)
\(1101110_2 = 64 +32 + 0 + 8 + 4 + 2 + 0\)
\(1101110_2 = 110_{10}\)
Lastly, convert \(110_{10}\) to hexadecimal using division and remainder rule
\(110/16 \to 6\ R\ 14\)
\(6/16 \to 0\ R\ 6\)
Write the remainder from bottom to top;
\(110_{10} = 6(14)_{hex}\)
In hexadecimal
\(14 \to E\)
So, we have:
\(110_{10} = 6E_{hex}\)
Hence:
\(1001011_2\) \(+\) \(100011_2\) \(=\) \(6E_{hex}\)
A subquery nested in a select clause cannot contain an order by clause.
a. true

Answers
The answer is true. A subquery nested in a select clause cannot contain an order by clause.
This is because the outer query's order by clause will be applied to the entire result set, including the results of the subquery. If the subquery has its own order by clause, it would create ambiguity and could potentially result in errors or unexpected results. Therefore, to avoid any conflicts or confusion, a subquery nested in a select clause should not contain an order by clause.

Answers
A Dante device's average default delay is 1 ms. This is enough for a very big network that consists of 100 megabit lines to Dante devices and a gigabit network core (with up to 10 hops between edge switches).
The term "latency" refers to the minute amount of time (10 milliseconds in the case of Dante Via) that is added to each audio stream. Via may 'packetize' the audio from the source and send it across the network to the destination before it is scheduled to be played out thanks to the minor delay. Audio and control are combined into one potent network because computer control and recording signals go over the same connections as the audio data.

not recording. What would you do?
Answers
When performing a 12-lead ECG, if you notice that the racing line is very thick and hard to view, and one of the leads is not recording, there are several steps you can take:
1. Ensure proper placement of the leads: Verify that the leads are correctly attached to the patient's body, following the standardized placement guidelines. Incorrect lead placement can result in a poor signal quality.
2. Check lead connections: Inspect the lead wires and electrodes for any loose or disconnected connections. Reattach or replace any faulty leads as necessary.
3. Clean the skin: Ensure that the skin is clean and free of oils or lotions, as they can interfere with the electrical signal. Clean the skin with an alcohol wipe if needed.
4. Adjust the gain: Increase the gain on the ECG machine to enhance the visibility of the racing line. This adjustment can make the waveform easier to interpret.
5. Troubleshoot the non-recording lead: If one of the leads is not recording, check the lead connection and electrode placement. If the issue persists, try replacing the lead with a new one.
6. Consult a healthcare professional: If the problem persists and you are unable to obtain a clear and accurate reading, consult a healthcare professional or an experienced ECG technician for assistance.
Remember, obtaining a clear and accurate ECG is crucial for making accurate diagnoses, so it's important to address any issues with the racing line and non-recording lead promptly and effectively.

Answers
Answer:
Asymmetric.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
There are two (2) main types of encryption techniques used in cryptography and these are;
I. Symmetric encryption.
II. Asymmetric encryption.
Asymmetric encryption is a type of cryptography which uses two mathematically linked keys, one key encrypting the data and the other decrypting the data. These two keys are generally referred to as a public key and a private key respectively.
This ultimately implies that, a pair of key (two keys) that are different in values is required or needed to make a computer system secured.

Answers
One common way to decrease the IT spending of a company is B) move toward cloud computing.
Cloud computing refers to the delivery of computing services, such as servers, storage, databases, software, and analytics, over the internet ("the cloud"). By using cloud services, companies can avoid the upfront costs and ongoing maintenance of their own IT infrastructure, and instead pay for what they use on a pay-as-you-go basis.
This can lead to significant cost savings, as companies no longer need to invest in expensive hardware and software, or hire and train specialized IT personnel to manage it. In addition, cloud computing can provide greater scalability, flexibility, and accessibility, allowing companies to easily adjust their IT resources based on their changing needs.

1. True
2. False
Answers
An instance of a derived class can be used in a program anywhere in that program that an instance of a base class is required. 1. True
Can a derived class instance be used wherever a base class instance is required?An instance of a derived class can indeed be used in a program anywhere that an instance of a base class is required. This is a fundamental concept in object-oriented programming known as polymorphism.
Polymorphism allows objects of different classes to be treated as objects of the same base class, enabling code reuse, flexibility, and extensibility.
Inheritance is a key mechanism in object-oriented programming, where a derived class inherits the properties and behaviors of a base class. By using inheritance, we can create a hierarchy of classes, with the derived class inheriting the characteristics of the base class while adding its own unique features.
When a function takes an instance of a base class as a parameter, it can also accept an instance of any derived class that inherits from the base class. This is because the derived class is a specialization of the base class and includes all its functionality. The function can work with the base class methods and data members and can also access the additional methods and data members specific to the derived class.
This concept of substitutability allows for code reuse and promotes flexibility and scalability in software development. It enables us to write code that operates on a generic base class, which can later be extended by deriving new classes with specialized behaviors. This way, we can write more generic and modular code that can accommodate future enhancements without modifying existing code.

A loop is used in computer programming to perform a set of instructions or a block of code repeatedly without having to start from scratch each time. The code block is executed in accordance with a particular situation. Loops are the control structures in a program.
Variables are data values that can change depending on the user's response to a query, such as their age. During the running of a program, variables could change. A variable is a piece of memory. It has a name that's connected to that place. The memory location is where data is stored. Variable is irrelevant. In other words, it doesn't matter what b I enter.

Answers
Answer:
Centrifugation.
Explanation:
When the liquid is spun rapidly, the denser particles are forced to the bottom and the lighter particles stay at the top. This principle is used in centrifugation.
Centrifugation can be defined as the process of separating particles from a liquid solution according to density, shape, size, viscosity through the use of a centrifugal force. In order to separate these particles, the particles are poured into a liquid and placed in a centrifuge tube. A centrifuge is an electronic device used for the separation of particles in liquid through the application of centrifugal force. Once the centrifuge tube is mounted on the rotor of the centrifuge, it is spun rapidly at a specific speed thereby separating the solution; denser particles are forced to the bottom (by moving outward in the radial direction) and the lighter particles stay at the top as a result of their low density.
