Explanation:
In monitor synchronisation, one of the scheduling approaches is the Mesa style scheduling.
The Mesa style scheduling in a Mesa monitor, the released thread due to a signal is also in the inactive state. Note that those inactive threads had the lock previously; but, they are unable to re-acquire it.
There are six ways it can carry out scheduling, they are as shown in the answer.

Answer:
This is not true
Explanation:
The optimal Huffman code is used to encrypt and compress text files. It uses fixed-length code or variable-length code for encryption and compression of data.
The professor's character code is similar to Huffman's variable-length coding which uses variable length od binary digits to represent the word strings. The file size of the text file above is;
= 6 x 1 + 2 x 2 + 3 x 2 + 2 x 2 + 8 x 1 = 28 bits
This would be the same for both cases.
The encrypt would be the problem as the encoded and decoding of the characters B and E may cause an error.

The answer to this question is given below in this explanation section.
Explanation:
A database management system(DBMS) is a software package designed to define,manipulate,retrieve and manage data in a database.A DBMS generally manipulates the data itself the data format,field names,record structure and file structure.It also defines rules to validate and manipulate this data.
Database management system are setup on specific data handling concepts,as the practice of administrating a database evolves. The earliest database only handled individual single pieces of specially formatted data.Over time, the models for database management systems have changed considerably.
The earliest types of database management systems consisted mainly of hierarchy and network models.
- The hierarchy model is one where each node or component has a child parent relationship with one other node or components.
- In the network model,the difference is that a single component can have multiple relationships think of this as a single node being able to multicast connections.
However over time these models became overtaken by something called a relational database.In this relational database model individual components have attributes that are linked to their identities through a database table design.The rows and columns of an individuals database table include those identities and attributes in such a way that traditional structured query language or SQL can be used to pull various kinds of information on these relations models.
