In a Web-based database, middleware is used to transfer information from the organization's internal database back to the Web server for delivery in the form of a Web page to the user. True or False?
Answer: True
Explanation:
Yes, the given statement is true that the web based database used the various types of database applications for transferring the information or data.
The web database applications are basically designed so that the users managed and easily access the information by using the internet. It is works as the middleware form for transferring the data from the internal database of an organization to the web server and it is known as web page for the user interface. We can store various types of business and also personal related data by using the web database.In a(n) ____ design, the remote user’s keystrokes are transmitted to the mainframe, which responds by sending screen output back to the user’s screen.A. closedB. distributedC. openD. centralized
Answer:
D. centralized
Explanation:
Centralized design is a type of computing architecture where all or most of the processing/computing is performed on a central server. Centralized computing enables the deployment of all of a central server's computing resources, administration and management. The central server, in turn, is responsible for delivering application logic, processing and providing computing resources to the attached client machines.
Therefore in centralized design, the remote user’s keystrokes are transmitted to the mainframe, which responds by sending screen output back to the user’s screen
Final answer:
The correct answer is D. In a centralized design, a user's keystrokes are sent to the mainframe, which processes the input and sends the output back to the user's screen.
Explanation:
In a centralized design, the remote user's keystrokes are transmitted to the mainframe, which responds by sending screen output back to the user's screen.
This setup is typical of traditional mainframe environments, where a powerful central computer (the mainframe) handles processing and storage, while user terminals mainly serve as input and output points.
The centralized computing model contrasts with distributed computing, where processing is spread across multiple machines.

Which of the following statements about constructors are true? Check all that apply.
a.A constructor is the code that is called when you use the 'new' keyword.
b.A constructor is declared without a return type.
Answer:
a. Partly True
b. True
Explanation:
(a) "new" keyword or syntax is used for the constructors while working in Perl and Moose object system for Perl.
For Visual Basics .Net, keyword "New" is used
For Python, "___new___" is used which allocates memory for instance and receives class as an argument.
For Objective-C, "alloc" and "init" are used for constructor method. "alloc" allocates memory for the instance and "init" handles the bulk of initializing the instance. Whereas, the "new" keyword calls both "alloc" and "init" for class instance.
(b) A constructor does not return any value because it is called by the memory allocation and object initialization code in the runtime and not directly by your code.
A TCP connection has reached a steady state and transmits data at a constant rate. List as many factors as you can that determine the transmission rate reached by the connection? Include the application and the operating system on both ends of the connection in your consideration.
TCP connection:
Once TCP connections reached steady state that makes end user that connectivity is stable. But end user has to do analysis the pinging time ready. for example in operating system command prompt mode ends user have to ping designation tcpip address.
Computer A
In command prompt mode end user try ping 10.10.10.10 –t (i.e. Computer B tcpip Address). End user tries to ping destination tcpip address if result comes in milliseconds then it is good connectivity rate.
Same away
Computer B
In command prompt mode end user try ping 10.10.10.20 –t (i.e. Computer A tcpip Address). End user tries to ping destination tcpip address if result comes in milliseconds then it is good connectivity rate.
End user can also check by executing TRACERT commands on designation tcpip address. End user can find how the flow of network packets travels.

In cell c11, enter a formula to reference the date stored in cell b7. insert a nested function in cell c12 to calculate the date for the next payment. nest the year, month, and day functions within the date function. add 1 to the month result. copy the function to the range c13:c34.
Final answer:
The student needs to reference a date in one cell and create a formula for the next payment date in another cell using spreadsheet functions. In cell C11, they will reference the date with =B7, and in cell C12, they will use a nested formula =DATE(YEAR(B7), MONTH(B7) + 1, DAY(B7)) which is then copied down to subsequent cells.
Explanation:
The student is asking about how to use spreadsheet functions to reference and manipulate dates. In cell C11, the formula to reference the date stored in cell B7 would simply be =B7. For cell C12, the nested function to calculate the next payment date, adding one month to the current date, would be something like =DATE(YEAR(B7), MONTH(B7) + 1, DAY(B7)). This uses the YEAR, MONTH, and DAY functions nested within the DATE function to construct the new date. Once the function is entered in cell C12, it can be copied down the range C13:C34 to apply to additional cells. Remember, these functions and formulas are typical of spreadsheet software like Microsoft Excel ora Sheets.

Answer:
The answer is Symmetric Key cryptography
Explanation:
Because this method of encryption allow both parties to use the same key and cipher to encode and decode the ciphertext.
Answer:The
The answer is User Cs uses the Public Key.
Explanation:
Public-key cryptography refers to a cryptographic system that uses pairs of keys: one that is a private keys,which are seen only by the use and public keys, which may be used widely by different users.
The generation of such keys depends on algorithms that are cryptographic based on mathematical problems to provide function that is one way. A strong security only needs keeping the private key private; the public key can be openly distributed among users without compromising security.
An easy way to remember the difference between encoding and decoding within the communication process is to think of encoding as the message the sender intends to say, whereas decoding can be thought of as what the receiver actually ______.
Answer:
An easy way to remember the difference between encoding and decoding within the communication process is to think of encoding as the message the sender intends to say, whereas decoding can be thought of as what the receiver actually hears.
Explanation:
Encoding and decoding are the terms used in communication.Encoding can be defined as the process or way in which the message you want to convey is created. This means the words we expel to demonstrate that what we want to say are known as encoding. Decoding on the other hand involves the interpreting of the message. It means, understanding the message that has been sent is known as decoding.As communication process have two members say sender and receiver, so sender is associated with encoding and receiver with decoding.i hope it will help you!

Ensuring the uninterrupted flow of information' describes which key communications and information systems principle?
A. Security
B. Reliability, Scalability, and Portability
C. Resilience and Redundancy
D. Interoperability
Answer: C) Resilience and Redundancy
Explanation:
According to the principle of communication and information system , redundancy is the factor that maintains the continuous flow of message or data even when failure is experienced in network by adding alternate or extra component in infrastructure for support.Resilience is the factors that helps network to persist even in the state of faults by keeping the main function working and recovering the fault to maintain the flow of data.Other options are incorrect because security is protection of data. Reliability factor means dependency , scalibility is changing scale of network and portability is changing position of components. Interoperability is exchanging information with devices and making use of it.Thus, the correct option is option(C).
Answer:
C. Resilience and Redundancy
Explanation:
Robust systems are characterized by having the ability to maintain their essential performance conditions despite receiving disturbances or noise. Robustness is the ability of a system to absorb stress and continue functioning, particularly when the system is subjected to unpredictable variations in its scope of performance.
The redundancy, consisting of the duplication of the critical components of a system, is developed with the purpose of granting robustness to the systems, so that in the event of the failure of a component that could jeopardize the main task or objective of the system, there is an alternative capable of replacing the system that suffers from a failure.
Robustness or resilience is characterized by two important aspects, the first is resistance to change or flexibility that is expressed as the ability of a system to resist a disturbance without undergoing irreversible change and the second is the ability of a system to recover.
Which line in the following program contains the header for the showDub function? 1 #include 2 using namespace std; 3 4 void showDub(int); 5 6 int main() 7 { 8 int x = 2; 9 10 showDub(x); 11 cout << x << endl; 12 return 0; 13 } 14 15 void showDub(int num) 16 { 17 cout << (num * 2) << endl; 18 } 1. 4 2. 6 3. 10 4. 1
The header for the showDub function is contained in line 4.
The header of a function in C++ is the first line where the function is declared before it is defined or called. It specifies the return type, the name of the function, and the parameters the function will take, if any. In this case, line 4, 'void showDub(int);' is where the function showDub is declared, making it the function's header. This is a forward declaration and tells the compiler what the function looks like. This allows the function to be called before it is fully defined, as seen in line 10 within the main function. The actual definition of the showDub function does not occur until line 15, where the function's operations are fully described.
____ is an industry-standard protocol that makes it possible for software from different vendors to interact and exchange data
A. JDBC
B. JVC
C. ODBC
D. OEC
Answer: (C) ODBC
Explanation:
ODBC stand for the open database connectivity and it is one of the industry standard protocol in which the ODBC driver uses the interface for access the data in the DBMS (Database management system).
The open system connectivity uses the structure query language standard for accessing the given information or data. The main aim of the ODBC is that it makes the independent operating system, software and also various types of database system. In the open system connectivity, we can easily exchange data and also interact with the different types of vendors.Therefore, Option (C) is correct.
You have a small wireless network that uses multiple access points. The network uses WPA and broadcasts the SSID. WPA2 is not supported by the wireless access points.
You want to connect a laptop computer to the wireless network. Which of the following parameters will you need to configure on the laptop? (Select two.)
a) AES encryption
b) TKIP encryption
c) Channel
d) BSSID
e) Preshared key
Answer:
b) TKIP encryption,e) Preshared key
Explanation:
The parameters that need to be configured on the laptop include the Temporal Key Integrity Protocol (TKIP) and the Preshared key. TKIP is an older wireless protocol that encrypts data at bit level. It is less secure as compared to the Advanced Encryption Standard (AES), AES works well with WPA2 which is not supported by the access point. The preshared key is the access password used on a shared secure channel. It is also used to validate users on the WiFi network. Once the two parameters are configured the laptop will have access to the network
To connect a laptop to a WPA wireless network, configure TKIP encryption and enter the preshared key. AES is used with WPA2 and is not applicable here, while the channel and BSSID are generally managed automatically.
Explanation:When connecting a laptop computer to a wireless network that uses WPA and broadcasts the SSID but does not support WPA2, you will need to configure certain parameters on the laptop. Since the network uses WPA, the compatible encryption that should be set up on the laptop is TKIP encryption since AES is typically used with WPA2. Additionally, you will need to enter the preshared key, which is a secret password or passphrase used to authenticate devices and grant access to the wireless network. Channels and BSSIDs are generally managed by the access points and are not typically configured manually on client devices unless troubleshooting specific connection issues or optimizing the network.
you are the server managert for your company you hae just installed a new windows server you need to design a backup and recovery strategy for the server that meets the following requirements you will use windows tools for the backups backups are to be taken to an offsiet location for storage aftrer they are performed backups should only save data changed since the lasty backup you need to be able to recover invidual files and folders whaty should you do
