Explanation:
I'll assume the question is about the use of constants in QBasic because consonants do not have any special function or usage in QBasic.
In simple terms: In QBasic, constants are used to represent elements that do not change in value during program execution.
Take for instance, you intend to use in your program.
Its value is
So, 3.142 will always be a constant in your program. One of the ways it can be used in a program is:
10 LET PI = 3.142
<em>The above represents a numeric constant. QBasic also have string constants.</em>

Explanation:
The major reasons why computer processes are suspended or terminated are:
1. When there is insufficient memory for successful completion of the process
2. When there's an unauthorized access of any of the computer resources by the process.
It is possible that some processes are terminated why some are suspended because, when the system runs out of memory, the running processes are put on hold until the system is able to create free memory space for the completion of the process. In this case the process is suspended. But if the system cannot provide enough space for the process, the process is terminated.
In the example provided in this exercise, some of the processes were suspended because the system wants to create free memory space for their completion while others are terminated either because the available space is not sufficient for their completion or they want to access an unauthorized resources on the system.
Answer:
C. how and where the data are physically arranged and stored.
Explanation:
The physical view as the name implies describes how and where the data are physically arranged in the database. This deals with the physical arrangement of data in the database. This user usually view the database in a logical way. e.g table. The physical arrangement is usually used by database specialists. There can be multiple logical view of a database but just a single view of the physical view.
Answer:
Data base administrator
Explanation:
The data base administrator is a component of a data model that defines the boundaries of a database, such as maximum and minimum values allowed for a field , constraints and access methods. Database is structured from of data sets.
The data in database use to come from different sources that data must have some boundaries. Database administrator is a part of DBMS. The authorized DBA is responsible for the integrity of data and keeping the data in good manner so at the time of need the data could be accessed rightly. Storage of data has to be done in a way that at time of use or at the time of retrieval the data must be accessed frequently and easily.
Database administrator is responsible to put constraint on the database, for example a person could enter how many digits or alphabets in the required fields or records. Otherwise user could enter irrelevant and lengthy data in the fields so it would be hard to manage data on server due to shortage of the memory. By putting such constraints the size of data could be managed and relevant data could be saved. Secondly, constraints use to be put for security purpose to keep information confidential and secure the certain constraints are mandatory and the data base administrator is responsible for such constraints.
Once the user use to store data on database the data safety and integrity is most important for them. So that DBA will arrange the data in organised form which will give quick access and data length will be managed properly so user could not enter lengthy data to full the repository. DBA put security constraint as well for the satisfaction of user and secure use of the database.
So we could say that dba is most important part of DBMS of any organization.

What is a proxy server?
A proxy server i<u>s a server program used in computer networking that stands between a client and the server supplying the resource that the client is requesting</u>. A proxy server is a server program used in computer networking that <u>stands between a client and the server</u> supplying the resource that the client is requesting.
Proxies add a <u>significant degree of protection to your machine.</u> They can be configured as firewalls or web filters to defend your computer against online dangers like viruses.
<u>This added security from a </u><u>proxy </u><u>server is also beneficial when used in conjunction with a secure web gateway or other email security tools</u>. Using this method, you can filter traffic based on the level of security it offers or the volume of traffic your network—or certain computers—can handle.
