Answer:
It gives a new string
Explanation:
In programming; when two or more strings are concatenated by a concatenating operator, the result is always a new string.
From the question, we have that
str1 = "Good
str2 = "Evening"
Let's assume that + is the concatenating operator;
str1 + str2 = "Good" + "Evening" = "GoodEvening"
The result of concatenating str1 and str2 is a new string "GoodEvening" while str1 and str2 still maintain their original string value of "Good" and "Evening"

Answer:
Explanation:
A computer virus is a form of malicious software that piggybacks onto legitimate application code in order to spread and reproduce itself.
Like other types of malware, a virus is deployed by attackers to damage or take control of a computer. Its name comes from the method by which it infects its targets. A biological virus like HIV or the flu cannot reproduce on its own; it needs to hijack a cell to do that work for it, wreaking havoc on the infected organism in the process. Similarly, a computer virus isn't itself a standalone program. It's a code snippet that inserts itself into some other application. When that application runs, it executes the virus code, with results that range from the irritating to the disastrous.
Computer virus symptoms
How can you tell if a virus has slipped past your defenses? With some exceptions, like ransomware, viruses are not keen to alert you that they've compromised your computer. Just as a biological virus wants to keep its host alive so it can continue to use it as a vehicle to reproduce and spread, so too does a computer virus attempt to do its damage in the background while your computer still limps along. But there are ways to tell that you've been infected. Norton has a good list; symptoms include:
Unusually slow performance
Frequent crashes
Unknown or unfamiliar programs that start up when you turn on your computer
Mass emails being sent from your email account
Changes to your homepage or passwords
A DBMS acts as a conduit between the database and the applications that will use it, enabling users to access, modify, and control how the data is arranged and optimized.
Data points that are connected to one another are stored and accessible in a relational database, which is a form of database. The relational model, an easy-to-understand method of representing data in tables, is the foundation of relational databases. Data items are requested from the database by application programs, which are created using a combination of the DBMS's data manipulation language and a traditional programming language. The DBMS locates and provides the data elements requested by the application programs.
