The question statement is true that there is overlap in the subject of study in different information technology discipline.
It is true that there is overlap in the subjects of study in the different information technology disciplines. The disciplines are collectively known as the disciplines of computing. Computer science, computer engineering, information technology, information systems, and software engineering all come in the realm of computing disciplines. These are the five distinct computing disciplines with overlapping subjects of study.
These disciplines are said to be interrelated as computing is their main area of study, yet they are distinct since each has its own curricular focus, research perspective and career prospects.
- Computer science: Computer science as the discipline deals with designing and implementation of operating systems and software, including the study of computation and computability.
- Computer engineering: As a discipline, computer engineering concerns with making different parts of computers work together. Research, design and development of computer-based equipment and hardware are also area of study in this discipline.
- Information technology: Information technology as an area of study is mainly concerned with automation of business operations. It provides support through software and computers to handle data and innovate business processes.
- Information systems: Information system as a discipline provides area of study which makes people able to apply advance information technology to solve today’s problem primarily within an organizational and enterprise settings.
- Software engineering: Software engineering is the discipline concerns with the designing, development, maintenance, testing, and evaluation of computer software and applications to solve real world problems.

Answer:
Hospices
Explanation:
A/An <u>Hospices</u> is operated on the principle that the dying have special needs and wants that hospital personnel are too busy to handle.
Answer:
Giving that: The following is a sequence of undo-log records written by 2 transactions T and U:
< START T >;
< T,A,10 >;
< START U >;
< U, B, 20 >;
< T, C, 30 >;
< U, D, 40 >;
< Commit U >;
< T, E, 50 >;
< Commit T >;
1. < START U >
Recovery action in this case will be undo(-1) and undo(0). All restored to its original Value
log records < T, A, 10 >, < T, abort >; as written out
2. < T, E, 50 >
Recovery action in this case will be undo(8) and redo(0). A and C is restored to its original value, B and D are set to 20 and 40
log records <T, C, 30 >, < T, A, 10 >, < T, abort > are written out
3. < Commit T >
Recovery action in this case will be redo(7) and redo(4). A and C are set to 10 and 30, B and D are set to 20 and 40
Answer: (C) MAC
Explanation:
MAC is stand for the message authentication code and it is one of the key dependent hash function. Message authentication provide the data integrity and also the origin of data authentication.
- It basically allow the specific recipients known as the holder of the symmetric key.
- The message authentication code uses the CBC (Cipher block chaining) mode for constructing the MAC algorithm and it also uses the block cipher for the conjunction by using the CBC operations.
On the other hand, all the options are incorrect as they are not the key dependent hash function.
Therefore, Option (C) is correct.
In Java programming, the <u>%s</u> format specifier can receive any type of Java data.
<h3>The kinds of data type.</h3>
In Computer programming, there are five recognized data types and these include:
- Floating point type (float).
<h3>What is a string?</h3>
A string is a data type which is typically used for data values that comprises ordered sequences of characters.
In Java programming, strings can be used to represent all Java data types such as numbers, Boolean, strings, etc. Also, the <u>%s</u> format specifier can be used by a programmer or software developer to receive any type of Java data.
