The string that was actually transferred following bit stuffing is a Hamming code is used to convey messages of eight bits.
Explain about the Hamming code?Data transmission or storage faults can be found and fixed using the error correction method known as Hamming code. It necessitates including more parity bits with the data. Error-correcting code (ECC) RAM frequently uses it.
The number of places at which two corresponding bits of data can differ is known in information technology as the Hamming distance. It is frequently employed in a variety of mistake correction processes or in the evaluation of opposing strings of data or pieces of information.
Hamming codes are perfect codes because they have a minimum distance of three and a block length that results in the highest achievable rate for codes. In order to automatically repair errors caused by punched card readers, Richard W. Hamming created the Hamming codes in 1950.

Answer: Ubiquitous computing
Explanation:
You've just started a new job as a data analyst. You're working for a midsized pharmacy chain with 38 stores in the American Southwest. Your supervisor shares a new data analysis project with you.
She explains that the pharmacy is considering discontinuing a bubble bath product called Splashtastic. Your supervisor wants you to analyze sales data and determine what percentage of each store's total daily sales come from that product. Then, you'll present your findings to leadership.
You know that it's important to follow each step of the data analysis process: ask, prepare, process, analyze, share, and act. So, you begin by defining the problem and making sure you fully understand stakeholder expectations.
One of the questions you ask is where to find the dataset you'll be working with. Your supervisor explains that the company database has all the information you need.
Next, you continue to the prepare step. You access the database and write a query to retrieve data about Splashtastic. You notice that there are only 38 rows of data, representing the company's 38 stores. In addition, your dataset contains five columns: Store Number, Average Daily Customers, Average Daily Splashtastic Sales (Units), Average Daily Splashtastic Sales (Dollars), and Average Total Daily Sales (All Products).
You know that spreadsheets work well for processing and analyzing a small dataset, like the one you're using. To get the data from the database into a spreadsheet, what should you do?
Download the data as a .CSV file, then import it into a spreadsheet.
Using the knowledge in computational language in python it is possible to write a code that dataset contains five columns: Store Number, Average Daily Customers, Average Daily Splashtastic Sales (Units), Average Daily Splashtastic Sales (Dollars), and Average Total Daily Sales (All Products).
Writting the code:def run_command(cmd):
fields = map(unescape, cmd.split(";"))

Polymorphism is divided into two syllables namely, Poly which means many and Morphism which means form. In science, polymorphism is a principle in biology in which organisms or species have many forms and stages. This principle is also applied to the Java language.
Polymorphism in OOP is an OOP concept where class has many "forms" of different methods, even though the names are the same. The meaning of "form" is that the contents are different, but the data types and parameters are different.

A technician, Joe, has been tasked with assigning two IP addresses to WAN interfaces on connected routers. In order to conserve address space, which of the following subnet masks should Joe use for this subnet?
A. /24
B. /32
C. /28
D. /29
E. /30
E
In order to conserve address space, Joe should use the /30 subnet mask for this subnet.
What is a subnet mask?
The host bits and network bits are both set to all 0s to generate a 32-bit value known as a subnet mask. The subnet mask delineates the network and host addresses in the IP address in this manner.
Each device has a unique IP address that is made up of two parts: the client or host address and the server or network address. A DHCP server or a human being must either manually or automatically configure IP addresses (static IP addresses).
The subnet mask separates the IP address into the host and network addresses, designating which parts of the IP address belong to the network and which parts belong to the device.

you run the comman hostname server1 and issue the reboot command you notice that the host name has reverted back to what it was before the reboot
Using hostnamectl, set-hostname server1. To set the system's hostname and get the DNS name, use the hostname command in Linux.
What is command ?A command is a request sent to a computer program to do a certain task in computing. It may be transmitted through a command-line interface, such as a shell, as input to a network service as part of a network protocol, as an event in a graphical user interface triggered by the user picking an item from a menu, or by any of the following methods: The command is one of the Linux operating system's features. All simple and difficult tasks can be completed by running commands. To execute the commands, utilize the Linux terminal.

The primary difference between simulation models and other types of spreadsheet models is that simulation models contain which of the following?
A. random numbers
B. output cells
C. constraints
D. deterministic inputs
The main difference between other spreadsheet models and simulation models is that the input variable cells in the simulation contain random numbers.
Random Numbers in Simulation Modeling
As the term suggests, random numbers are numbers that are chosen by chance at random, from a pool of numbers. All numbers in a given distribution have the same probability of being randomly selected.
Random numbers appear in a given distribution only when two conditions are met: Values are evenly distributed over a given interval or series, and it is impossible to predict future values based on past or present.
For numbers in sequence or distribution to be truly random, they must be independent. Numeral independence means that there is no correlation between successive numbers. In addition, these numbers should appear in the distribution with approximately the same frequency.
