Answer:
A database is a collection of information, generally stored as computer files. The information it contains can be stored, updated, organized, output, distributed, searched, and analyzed. A filing cabinet full of folders and papers would be classified as an unstructured file. A structured file uses a uniform format to store data for each person or thin in the file
Explanation:
A database is a systematically structured collection of data or information that is usually digitally and electronically stored within an computer
Unstructured files are large number of files that are not stored based on structural properties, or kept in an organized format
Structured file are files that are keeps data in a uniform organized structural format

why the internet is not policed
Answer:
The Internet allows people to circumvent law by committing criminal acts from areas where their activities are not illegal. Those areas will always exist, and thus new regulations will be just as ineffective as the old ones are ["Net Needs Law Enforcement, Author Says,"]. But Internet traffic is marked with IP addresses, and those addresses can be tied to specific networks with specific locations. Shouldn't it be possible to separate traffic based on the originating network and treat data coming from relatively insecure locations differently than data coming from relatively secure locations? It would be much harder for someone in a rogue nation to hack a network if he had to hack an intermediary network first. And unlike government regulation, which has zero impact in areas where these threats are likely to originate, separating traffic by location might actually work
4. Calculate the standard deviation for the following data set: Foundations of Technology Engineering byDesi OITEEA . . Data Set = 4, 14, 6, 2, 7, 12 217 ,
Answer:
[tex]\sigma_x = 5.68[/tex]
Explanation:
Given
[tex]x = 4, 14, 6, 2, 7, 12 2,17[/tex]
Required
The standard deviation
First, calculate the mean
[tex]\bar x =\frac{\sum x}{n}[/tex]
So, we have:
[tex]\bar x = \frac{4+ 14+ 6+ 2+ 7+ 12 +2+17}{8}[/tex]
[tex]\bar x = \frac{64}{8}[/tex]
[tex]\bar x = 8[/tex]
The standard deviation is:
[tex]\sigma_x = \sqrt{\frac{\sum(x - \bar x)^2}{n-1}}[/tex]
So, we have:
[tex]\sigma_x = \sqrt{\frac{(4 - 8)^2+ (14 - 8)^2+ (6 - 8)^2+ (2 - 8)^2+ (7 - 8)^2+ (12 - 8)^2+ (2 - 8)^2+ (17 - 8)^2}{8-1}}[/tex]
[tex]\sigma_x = \sqrt{\frac{226}{7}}[/tex]
[tex]\sigma_x = \sqrt{32.2857}[/tex]
[tex]\sigma_x = 5.68[/tex]

You are concerned that if a private key is lost, all documents encrypted using your private key will be inaccessible. Which service should you use to solve this problem
Answer:
Key escrow.
Explanation:
Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
In Cyber security, encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext.
Typically, an information or data that has been encrypted can only be accessed and deciphered by an authorized user.
Hence, if a private key is lost, all documents encrypted using that private key will be inaccessible to the users. Thus, the service that can be used to solve this problem is a key escrow because the cryptographic (private) keys kept in an escrow system are protected and would not be released to anyone other than the original user (owner).
A key escrow can be defined as a data security method of storing very essential cryptographic keys.
Simply stated, key escrow involves a user entrusting his or her cryptographic key to a third party for storage.
As a standard, each cryptographic key stored or kept in an escrow system are directly linked to the respective users and are encrypted in order to prevent breach, theft or unauthorized access.

Explanation:
In large organizations, there is a formal business function that includes developing an information policy, planning for data, overseeing logical database design and data dictionary development, and monitoring how information systems specialists and end user groups use data. __________ is responsible for information policy, as well as for data planning, data dictionary development, and monitoring data usage in the firm.
Answer:
Data administration.
Explanation:
Data management is a type of infrastructure service that avails businesses (companies) the ability to store and manage corporate data while providing capabilities for analyzing these data.
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Data administration is a strategic process that is typically responsible for establishing information policy, data planning, data dictionary development, and monitoring data usage in the firm.

Pratibha is working in a bank. She is creating a database to store the details of the bank customers. Which of the following fields of table Bank_Customer can be selected as primary key?
Answer:
Acc_No
Explanation:
Given
See attachment for table Bank_Customer
Required
Which field can be used as primary key
A field, once made the primary key, cannot contain duplicate entries.
This means that Pratibha has to select a field that can be unique to all customers.
From the table, we have:
Acc_No [tex]\to[/tex] No two customers can have the same account number
Cust_Name [tex]\to[/tex] Multiple customers can have the same name
DOB [tex]\to[/tex] Multiple customers can have the same date of birth
PAN_NO [tex]\to[/tex] No two customers can have the same pan number; however, pan number is often issued by tax department of a country.
Opening_Bal [tex]\to[/tex] Multiple customers can have the same opening balance,
Hence, the field to use as primary key is:
Acc_No

16. Which of the following is true about function return statements? A) A function can hold multiple return statements, but only one return statement executes in one function call. B) A function can hold only one return statement. C) A function can hold multiple return statements, and multiple return statements can execute in one function call. D) A function can have maximum of two return statements.
Answer:
A) A function can hold multiple return statements, but only one return statement executes in one function call
Explanation:
This is because each function can only return one value, whether it be an integer, String, or other object.
However, you can have a series of if-else statements, or case statements, to return a different value depending on information (within parameters, or variables.
Excellent. So, you can have multiple return statements, but the function will only end up executing one of these return statements and return a single value.
Hope this helps!
The statement "When there are multiple return statements but one return statement should execute the 1 function call" is true.
The following information should be considered:
This can be done as every function has only a return i.e. one value. It can be an integer, string, or any other thing. The function can't hold only 1 return statement.The function can't hold many return statements that execute one function call. The function can't have the utmost 2 return statements.Therefore, we can conclude that option A is correct.
