Answer: Option(b), (c) and (d) are correct.
Explanation:
According to the question,Sherri should check that process is right for motherboard as incorrect processor may not be able to process instruction and operation successfully and rapidly.
She should also check the warranty of the laptop.If in case , laptop is under warranty then she can get it repaired or replaced as per the policy of laptop company. Tear-down process can be verified so that laptop can be dismantled to investigate the components of processor that is causing issue in processing or other part is responsible for slow execution.Option (a) is incorrect because external devices is attached with motherboard with help of ports and cables.Processor is the actual unit that can cause slow execution and external devices are not responsible for it.Thus, the correct options is option(b),(c) and(d).Final answer:
Sherri should check if her laptop is still under warranty, ensure she has a compatible processor for her motherboard, and locate a guide for the proper teardown procedure before attempting to replace her laptop's processor.
Explanation:
Sherri should consider several factors before attempting to replace the processor on her laptop to address its slow performance. Firstly, she should verify that the laptop is not under warranty. Tampering with the hardware can void the manufacturer's warranty, and if the laptop is still covered, it might be more beneficial to seek professional repairs.
Secondly, it is essential to make sure you have the correct processor for the motherboard. Not all CPUs are compatible with every motherboard due to socket type, chipset, and power requirements. Lastly, Sherri should determine whether a teardown procedure is available to guide her through disassembling and reassembling her laptop safely.
Missing this step could lead to damage to the laptop components or render it completely inoperable when done incorrectly.

The term language can be defined as: Gestures, signs, objects, signals, and words that help people understand the world. A symbolic system through which people communicate and through which culture is transmitted. The exchange of gestures and signals for the purpose of reaching a consensus. Communication grounded in ideals, norms, and values.
Answer:
The correct answer is: "A symbolic system through which people communicate and through which culture is trasmitted".
Explanation:
To define the concept "language" is a hard task and yet nowadays language philosophers and scientists, such as professors and researchers, have been in a great deal to define this concept, including well known philosophers like Michel Foucault, Noam Chomsky, Mikhail Bakhtin, Ferdinand de Saussure, and others. According to them, the main conceptualization is that language is everything and everywhere, all comes to life and shape by letters, sounds, words, sentences, texts, and, therefore, are only real because language exists. However, there are a lot of other definitions for the concept, and here it is not the time to assess which one is true or not, important or not, or even radical or not, rather it is necessary to highlight that the commonest idea about language is expressed in the second option of the question: "A symbolic system through which people communicate and through which culture is transmitted". All the other options may present a simple idea concerning language's features, but they are not the best option to define the concept, which is much more complex and must be necessarily concerned to the production of culture.

Answer:
(A)symbolic system through which people communicate and through which culture is trasmitted
Explanation:
[Sebesta01] According to the author. Consider the list of potential benefits of studying concepts of programming languages. One of the benefits would be argued as follows:Many professional programmers have had little formal education in computer science; rather, they have developed their programming skills independently or through in- house training programs. Such training programs often limit instruction to one or two languages that are directly relevant to the current projects of the organization. Many other programmers received their formal training years ago. The languages they learned then are no longer used, and many features now available in programming languages were not widely known at the time. The result is that many programmers, when given a choice of languages for a new project, use the language with which they are most familiar, even if it is poorly suited for the project at hand. If these programmers were familiar with a wider range of languages and language constructs, they would be better able to choose the language with the features that best address the problem.This is an example of ____.
Answer:
Improved background for choosing appropriate languages
Explanation:
Based on the information provided within the question it can be said that this is an example of Improved background for choosing appropriate languages. Meaning that the an computer programmer that has learned many languages and gained the ability to choose the appropriate language for each situation is of much greater use to companies because of their increased efficiency.

Type two statements that use rand() to print 2 random integers between (and including) 100 and 149. End with a newline. Ex: 101 133 Note: For this activity, using one statement may yield different output (due to the compiler calling rand() in a different order). Use two statements for this activity. Also, srand() has already been called; do not call srand() again.
Answer:
srand(time(NULL)); //using srand once
cout<< (rand()%50)+100; // first random number
cout<<endl; //new line
cout<< (rand()%50)+100; //second random number
Explanation:
The srand function in C++ seeds the rand function. It means that the srand function provides rand function with a number which is used by the random function to generate random numbers.

What will be the value of ans after the following code has been executed?
int ans = 10;
int x = 65;
int y = 55;
if (x >= y)
ans = x + y;
A) 10
B) 120
C) 100
D) No value, there is a syntax error.
Answer:
Option B 120
Explanation:
There are three variables, ans, x and y given in the code. In beginning, the variable. ans, holds value of 10. And variable x and y hold value of 65 and 55, respectively. Since the value held by x is bigger than one held by y, the if condition is met and the statement ans = x + y will run. The execution of this statement will total x with y -> 65 + 55 and the initial value of ans is overwritten by the addition result which is 120.
Answer:
B) 120
Explanation:
In the first three lines of the code, three variables ans, x and y have been declared and initialized;
=> ans = 10;
=> x = 65;
=> y = 55;
On the fourth line and fifth line of the code, there is an if block statement that will get executed if the value of x is greater than or equal to that of y;
i.e
if (x >= y)
ans = x + y;
And since x = 65 and y = 55, it implies that x is greater than or equal to y.
Therefore the fifth line of the code will be executed
=> ans = x + y
=> ans = 65 + 55
=> ans = 120
Note:
Though the value of variable ans was initially 10 before the execution of the if statement, its new value 120 will replace the former value.
Therefore the value of ans after the code has been executed is 120

A constructor is a method that
Select one:
A. removes the object from memory.
B. returns an object of the class.
C. never receives any arguments.
D. performs initialization or setup operations.
Answer:
A constructor is a method that performs initialization or setup operations.
Explanation:
A constructor is a special method that is immediately called just after a memory space as been allocated to an object or when an instance of the class is created.
Constructors perform initialization or setup operations, such as assigning initial values to instance Variables. They are called "constructors" because they assist in constructing an object even though they actually don't construct the object.
A constructor is a method in object-oriented programming that initializes an object's state or performs setup operations. It is defined within a class and typically has the same name as the class.
Explanation:A constructor is a special method in object-oriented programming that is used to initialize an object's state or perform setup operations when the object is created. It is typically defined within a class and has the same name as the class. Constructors can take arguments or parameters, allowing for customization and initialization of objects based on specific values.
For example, let's consider a class called 'Car' in a car dealership system. The constructor of the 'Car' class could be used to set initial values for properties such as 'make', 'model', 'year', and 'mileage' when a new 'Car' object is created.

Computers and communication systems use _____ to represent information between computers and network systems.
Answer:
Data Code
Explanation:
In Data Communication, Data and Information are being assigned binary code in a digital system. This process is known as encoding system. This binary code helps computer of different architecture communicate with one another.
Data code is an encoding system for data in a computer. For text encoding we have ASCII, 7-bit ASCII, EBCDIC and Unicode. For non-text encoding, we have MIME, BinHex, Codec, etc. For video encoding, we have MPEG, YUV, YCbCr, chroma, e.t.c.
Computers and communication systems use **binary code** to represent information between computers and network systems. Binary code consists of two symbols, typically 0 and 1, which are used to encode data. This binary representation is fundamental for digital computing and communication, enabling the processing, storage, and transmission of information.
Computers and communication systems use **binary code** to represent information between computers and network systems. Binary code is a system of representing text or computer processor instructions using the binary number system's two binary digits, 0 and 1. This system forms the basis of all modern computing processes.
In binary code, each digit is referred to as a bit. These bits are grouped together to form bytes, typically consisting of eight bits. Bytes can represent a wide variety of data types, including characters, integers, and more complex data structures.
The primary advantage of binary code is its simplicity. Digital systems only need to distinguish between two states, which can be easily represented by electrical signals (on/off, high/low voltage). This reduces the complexity and cost of hardware.
Additionally, binary code enables reliable error detection and correction. Techniques such as parity checks and cyclic redundancy checks (CRC) ensure data integrity during transmission across networks. This binary representation is fundamental for digital computing and communication, enabling efficient processing, storage, and transmission of information across various platforms and devices.
