A user is claiming a host can be reached via the IP address but not through the name. What should a technician do first to resolve the problem?
Add an entry to the HOSTS file
Restart the client device
Restart the DNS server
Restart the DNS service
Answer:
Add an entry to the HOSTS file
Explanation:
Hosts File: A computer file in an operating system to trace the link between the IP address and the domain name or host names. In a computer system Hosts file is timely updated to resolve any website issue. When a hosts file entry is valid, computer system does not look on the DNS and link the entry to the addresses in the hosts files.
To resolve the users issue a technician must add the name and IP address in the hosts file. Computer system view the hosts files (list of hosts name link with IP addresses) to solve the issue with IP addresses.
Steps to add host file.

Final answer:
To display nonnegative integers in increasing order, you can use a sorting algorithm like selection sort.
Explanation:
To write a program that reads in three nonnegative integers from the keyboard and displays them in increasing order, you can use a sorting algorithm such as selection sort. Here's an example in Python:
# Read in three integers from the keyboard
num1 = int(input('Enter the first integer: '))
num2 = int(input('Enter the second integer: '))
num3 = int(input('Enter the third integer: '))
# Create a list with the three integers
numbers = [num1, num2, num3]
# Sort the list in increasing order
numbers.sort()
# Display the integers in increasing order
print('Integers in increasing order:', numbers)
This program prompts the user to enter three integers, creates a list with those integers, sorts the list in increasing order, and finally displays the integers in increasing order.

A device has an IP address of 10.1.10.186 and a subnet mask of 255.255.255.0. What is true about the network on which this device resides?
Only the last number of each IP address will be unique
Only the last two numbers of each IP address will be unique
Only the last three numbers of each IP address will be unique
All four numbers of each IP address will be unique
Answer:
Only the last number of each IP address will be unique
Explanation:
Subnet Mask is used to identify the two parts of the IP address. One is the network part that should be same for one network, and other is host part that will vary with number of computer or devices that are connected to the network.
Subnet mask is 32 bit address that are divided in 4 equal parts of 8 bits. Each 8 bit converted to decimal by varying different bits to generate 256 different decimal number combinations. It means we can vary the address range between 0 to 255. So If any 8 bit portion is 255 that means, in this section we cannot add host address.
For Example
In given case,
Subnet Mask = 255.255.255.0
That means first three portions are fixed and has been allocated for network part.
The forth portion is 0 that means we can change this portion in IP address up to 255 different addresses.
So the IP address that is given can be vary as:
10.1.10. 186
10.1.10 This portion is network portion, this cannot be vary.
only the number 186 is the unique address that is particularly assigned to the devices and is vary between 0 to 255.

a. COBOL languageb. programming languagec. ASCIId. machine language
Answer:
Option d is the correct answer.
Explanation:
Machine language is a language that is understood by any machine because it is made from the electric signal which has only two states on and off. On state refers to 1 and off-state refers to 1. The computer is also a type of machine so it can also understand machine language. The above question asked about the instruction which is made by 0's and 1's and it is used for the computers then the answer is Machine language which is described above and which is stated from the option d. Hence option d is the correct answer while the other is not because--
Option 'a' states about COBOL language which is an example of high-level-language, not the example of machine language.Option b states about the programming language which is a mixture of all language of computers.Option c states about ASCII which is not the correct answer.
The fundamental language of machines is machine code, often known as "machine language", and the further discussion can be defined as follows:
It is read by the operating system (CPU), is made up of digital binary integers, and seems to become a very long series of zeros and ones. If you have to deal with machine code, the command may seem to be a random string of zeros and ones, but it denotes precise operations and storage places.The wrong choice description can be defined as follows:
Its COBOL language is indeed an example of a high-level language, not a machine language.The programming language is a combination of all computer languages.ASCII is a character-to-code conversion code.Therefore, the final answer is "Option d".

Explain the difference between general-purpose and specialized applications. Also discuss the common features of application programs, including those with traditional and ribbon graphical user interfaces.
Answer:
General purpose programs are software that are designed for the general public, e.g. Word processor, music player, maps application. These softwares don't require you to be have some specific need or skill to use them.
Specialized programs are software that are designed for a specific group of users and/or profession, like CAD, Adobe premier, Visual Studio. These softwares require you to be associated with some profession to be able to use them. Also, specialized programs are usually not free and may require a licensing fee.
Common features of application programs include,
1. Saving file
2. Contact for help
3. Changing preferences
4. Exiting application
5. Viewing or signing in to your account
Explanation:
General-purpose computers can be configured to run various programs while special-purpose computers are designed for specific tasks. Apps are software applications that perform specific tasks and can feature either traditional or ribbon GUIs.
A general-purpose computer, like a universal Turing machine, is capable of running various programs, effectively transforming into a special-purpose computer for the duration of each program's execution. Special-purpose computers, on the other hand, are custom-built to run specific computations or tasks and cannot be dynamically reprogrammed.
Application programs, or apps, perform tasks separate from the core functioning of the computer, such as word processing, media playing, or accounting. These apps can have different user interfaces, with two common styles being traditional interfaces with dropdown menus and toolbars, and those with ribbon interfaces, popularized by Microsoft Office products, which organize tools into a set of tabs.
Graphical User Interfaces have evolved notably since the 1980s, with the introduction of elements like GUI, DTP, and WYSIWYG. These changes have significantly influenced how applications are interacted with and have broadened the application of computers.
In a graphical user interface, which of the following is a small symbol on the screen whose location and shape changes as a user moves a pointing device?

In the C++ statement pay = rate * hours; the * symbol is an example of
A. an operator.
B. an operand.no
c. a variable separator.
D. syntax.
E. none of the above.
Answer:
Option A is the correct answer for the above question.
Explanation:
In any programming language, An operator is used to perform some operation. It is fixed in between two numbers to perform the calculation. The above question asked about the Symbol ('*'), which is fixed in between two variables. so it is an operator which is called an arithmetic operator used for multiplication. So the operator is the correct answer which is stated from the option A. Hence A is the correct answer while the other is not because--
Option B states about an operand no but the operand is said to the variable or value.Option C states about a variable separator which is not the correct answer. Option D states about syntax which is also not correct.Option E states about none of the above but option 'A' is the correct answer.Final answer:
The correct answer is "an operator". In the provided C++ statement, the '*' symbol functions as an 'operator' used for performing multiplication between the variables 'rate' and 'hours'.
Explanation:
In the C++ programming language, symbols like +, -, *, /, and ** are utilized to conduct mathematical operations such as addition, subtraction, multiplication, division, and exponentiation, respectively. In the provided statement pay = rate * hours;, the * symbol is used to perform multiplication between two variables, rate and hours. This makes the * symbol an example of an operator.
Operators are special symbols in programming languages that initiate various kinds of operations or computations on data (known as operands) to produce a result. In this context, rate and hours serve as the operands, and the multiplication operation alters their values to produce a new value assigned to the variable pay. Hence, the correct answer to the question is A. an operator.

A digital currency that may be used online as a medium of exchange is called cryptocurrency. Strong cryptography is used in IT to secure financial transactions and to verify coin transfers.
What is digital currency?Digital currency is defined as a form of transaction that is electronically generated, stored, and transferred. Unlike the coins and notes of traditional currencies, digital currencies are not normally linked to any nation's government or represented in tangible ways. Any form of money or payment that solely exists in electronic form is referred to as digital money or digital currency.
For the first time in 2021, there were more transactions on Ethereum than there were on Bitcoin. It is safe to say that Ethereum is the most widely used blockchain network in the entire globe because it serves as the foundation network for the majority of NFTs and a large number of cryptocurrencies. Bitcoin and other cryptocurrencies present a new, decentralized form of money.
Thus, a digital currency that may be used online as a medium of exchange is called cryptocurrency. Strong cryptography is used in IT to secure financial transactions and to verify coin transfers.
