A network is divided into layers by a hierarchical structure, and each layer has a set of functions that specify how it fits into the overall network. This gives a network designer the ability to select the best hardware, software, and features to fulfill a specific purpose for that network layer.
What does architectural structural hierarchy mean?
When one element is given more weight than another, this is what is meant by hierarchy. In order to accentuate certain aspects and give them importance, architectural hierarchy is typically applied throughout the design and construction of buildings. Size, shape, and color can all be used to construct a hierarchy.
Why would one want to create a hierarchical design?
Hierarchical design aids in organizing and structuring your design because it allows you to enter a big design one element at a time. You may better understand the contents of each module in your design by organising it. As a result, the design process moves more quickly and debugging is made simpler.

Data members:
Employee Name
Father name
Emp ID (Number)
Job Category (Teacher, Officer, Staff, Labour)
Date of birth (Date)
Education (Matric, FSc, BS, MS, PhD)
Pay scale (number)
NIC (String)
Functionalities:
SetEmpInformation
UpdateEmpInformation
DeleteEmpInformation
Search and View Emp record by
Emp ID
Employee Name
Age
Job Catagory
Client class should have main function where it may have capacity of maximum 50 Employee records and You are only allowed to use arrays(list is not allowed).
User should be given choice whether to
Add New Employee record
Update Employee Information
Delete Employee Record
Search & view Employee
BY Emp ID
By Employee Name
By Age
By Job Catagory
Choices may be taken by using Input Message dialogs.
When user selects Add New Employee record, It must be kept in mind that no Teacher can have education lower than MS while No Officer can have lower than BS, No Staff can be lesser education than FSc and Labour should be with at least Matric Education. In the same manner for the Teacher pay scale can not be lesser than 18 while for the officer it cant be lesser than 17, the staff should be in between 11 and 16 and the pay scale for labour will be in between 1 and 10.
On update Employee Information, only education payscale and Job category can be updated.
When program is closed all the records should be saved into the file named as EmpDB.dat. all the objects must be serialized into the file. When the program starts if file EmpDB.dat is already present then user should have all required choices to apply on records available in file.
You will use java serialization to implement object serialization.
Note: Inputs should be taken by using Input dialogs and View should be by using showMessageDialog.
Emp ID should be unique and should not be set by user. It should be automatically assigned and Emp ID should start from 9000.

phonological memory represents the ability to code information phonologically for temporary storage in working or short-term memory. specifically the composite score provides an assessment of the functioning of the part of memory called the phonological loop, which provides a brief, verbatim storage of auditory information. a deficit does not inevitably lead to poor reading of familiar material but is more likely to impair decoding of new words, particularly words that are long enough to decode bit by bit, as a means of storing intermediate sounds. a deficit in phonological memory may not impair listening or reading comprehension for simple sentences but is likely to impair both listening and reading
Phonological memory is the capacity to retain knowledge based on speech in short-term memory. When reading and spelling, we place a lot of reliance on our phonological memory. Students are asked to repeat nonsensical words that are longer and more complicated or to memorize strings of numbers as a way of testing their memorization abilities.
What makes phonological memory crucial?
The development of vocabulary, processing of sentences and conversation, and learning to read are just a few of the skills that phonological working memory promotes (Perrachione et al., 2017).
How would one rate their phonological memory?
The "digit span," "digit span-running," and "nonword repetition" tasks are used to measure phonological working memory. Children must repeat lists of various lengths, ranging from 2 to 8 digits, as part of the "digit span" exercise. When kids are playing a game, this duty is provided to them.

Which of the following terms is the encrypted form of a message that is unreadable except to its intended recipient?
a. plain text
b. encryption algorithm
c. ciphertext
d. steganography
c)Ciphertext is the encrypted form of a message that is unreadable except to its intended recipient.
What is encryption?Encoding data is the process of encryption in cryptography. This technique transforms the information's initial plaintext representation into an alternate version known as ciphertext. Only parties with the proper authorization should be able to convert ciphertext to plaintext and gain access to the original data. Although encryption does not by itself stop interference, it does hinder a potential interceptor from understanding the material.
An encryption technique typically employs a pseudo-random encryption key produced by an algorithm for technical reasons. Without the key, it is feasible to decrypt the message, but doing so requires a lot of computer power and expertise for a well-designed encryption scheme. With the key provided by the sender to recipients but not to unauthorized users, an authorized recipient can quickly decrypt the communication.

Software redundancy techniques
When a software system provides the same functionality through the execution of distinct pieces, it is redundant.
What is redundancy?Redundancy has two functions: passive redundancy and active redundancy. Both features use excess capacity to avoid performance decreases from exceeding specification limitations without requiring human involvement. Excess capacity is used in passive redundancy to mitigate the impact of component failures.
Many software engineering techniques have made extensive use of redundancy, such as fault-tolerance and reliability engineering, as well as self-adaptive and self-healing programs.
Therefore, It is redundant when a software system provides the same functionality through the execution of distinct pieces.

For a given real-world problem like the one below, which algorithm will you use to solve it? How would you map the input information into the input required by the algorithm? What computational complexity the chosen algorithm has? Blizzard has come over the whole state, covering all highways with 40 inches of snow. To keep the distribution of food, roads between major cities need to be cleared, so that each major city can be reached from each other. But getting rid of the snow from a highway is expensive - $1000 per mile. You, member of the Emergency Services, need to devise a plan that keeps all major cities connected through cleared roads, with the cost of clearing as small as possible. You are given the list of distances (in miles) of direct connections (i.e. not going through any other major city) between the major cities. You have to do the math, and choose which of those connections should be cleared.
An algorithm is a written formula that is part of software that, when triggered, tells the tech what to do to solve a problem. Computer algorithms work with input and output.

counter = 1
for i in range(1, 100) :
counter = counter + 1
print(counter)
Why is the answer 100 not 101
Answer:
The answer is 100 because the range() function in the for loop is set to go from 1 to 100, not 1 to 101. The range() function is inclusive of the start value and exclusive of the end value, so in this case it will only go up to 99, not 100. Additionally, the counter variable is not being incremented correctly within the for loop. The correct syntax for incrementing a counter variable would be "counter += 1" instead of "counter = counter + 1".
