Answer:
10
Explanation:
This for-loop is simply iterating three times in which the value of x is being set to the value of x * 1. So let's perform these iterations:
x = 10
When i = 0
x = x * 1 ==> 10
When i = 1
x = x * 1 ==> 10
When i = 2
x = x * 1 ==> 10
And then the for-loop terminates, leaving the value of x as 10.
Hence, the value of x is equal to 10.

Answer:
Case-based reasoning.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.
In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.
This ultimately implies that, a data dictionary found in a computer database system typically contains the records about all the data elements (objects) such as data relationships with other elements, ownership, type, size, primary keys etc. This records are stored and communicated to other data when required or needed.
Basically, when a database management system (DBMS) receives data update requests from application programs, it simply instructs the operating system installed on a server to provide the requested data or informations.
Case-based reasoning is a problem-solving technique where each problem in a database is stored with a description and keywords that identify it. It is typically based on cognitive science and artificial intelligence.
The cell reference refers to a cell on a worksheet and can be used in a formula to point another location.
Explanation:
A cell reference is a range of cells on a worksheet that can be used in a formula to find the values or data you want to calculate using that formula.
There are two types of cell references relative and absolute. they both behave differently when copied to other cells. Relative references change when a formula is copied to another cell.
Absolute reference remains constant even if they are copied. In a formula multiplications are performed before subtraction.
It does not change when the formula is copied or moved to another cell.
Answer:NULL Scan
Explanation:RFC 793(Request for comments) is a type of RFC command labeled with the number 793 which can operate with the TCP protocol.They are sort of document form which is from IETF( Internet Engineering Task Force ).
The null scan is scanning protocol used by legal as well as illegal hackers for working in the transfer control protocol architecture. It is used for the identification of the the ports and holes in TCP servers.they can also have the negative impact if used by the illegal hackers.
Answer:
computers and Mobile phones ( including game consoles and tablets) are managed through device management
Explanation:
Device management includes a type of security software used to monitor,secure and manage systems such as mobile phones computer laptops and desktops, Tablets and smart televisions as well as Game consoles. It as well involves the management,operation and maintenance of the physical aspect of the systems from external threats/intruders
Anti virus software is an example of a device management software used to protect systems from malware, by detecting and removing them and also by preventing them.
Firewall is a complete device management tool because it detects and prevents intruders and virus from penetrating the system software
