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

Answer:
The image of truth table is attached.
Explanation:
In the truth table there is a separate table for the expression (A+B).C and for the expression (A.C)+(B.C) you can see in the truth table that the columns of (A+B).C is having same values as the (A.C)+(B.C).Hence we can conclude that (A+B).C is equal to (A.C)+(B.C).
Answer:
Visual Basic for Applications runs as an internal programming language in Microsoft Office applications such as Access, Excel, PowerPoint, Publisher, Word, and Visio. VBA allows users to customize beyond what is normally available with MS Office host applications by manipulating graphical-user-interface (GUI) features such as toolbars and menus, dialogue boxes, and forms. You may use VBA to create user-defined functions (UDFs), access Windows application programming interfaces (APIs), and automate specific computer processes and calculations. Macros can automate just about any task—like generating customized charts and reports, and performing word- and data-processing functions. Programmers,like replicating large pieces of code, merging existing program functions, and designing specific languages. VBA can also work in non-Microsoft settings by using a technology called "COM interface," which allows commands to interact across computer boundaries. Many firms have implemented VBA within their own applications, both proprietary and commercial, including AutoCAD, ArcGIS, CATIA, Corel, raw, and SolidWorks.
