Answer:
FFE3
Explanation:
The 16 bit binary representation of 29 = 0000000000011101
The corresponding hexadecimal representation = 001D
Taking 2s complement, the binary representation of -29:
Step 1 : 1's complement of 29 = 1111111111100010
Step 2 : Adding 1 to 1's complement to get the 2's complement => 1111111111100010 + 1
= 1111111111100011
Converting the binary representation to equivalent hexadecimal format: FFE3
Answer:
A query in a database is a request for information stored within a database management system (DBMS), which is the software program that maintains data.
SQL(Structured Query Language ( is a standard language for storing, manipulating, and retrieving data in database.
Five types of SQL queries are:
1) Data Definition Language (DDL).
used to define and modify the structure of a database.
2) Data Manipulation Language (DML).
used to manipulate (change) the data in the database.
3) Data Control Language(DCL).
used for access control and permission management for users in the database.
4) Transaction Control Language(TCL).
used for maintaining consistency of the database and for the management of transactions made by the DML commands.
5) Data Query Language (DQL).
used for performing queries on the data within schema objects.
Answer:
The answer is "Option A".
Explanation:
The Dot matrix printer is also known as an impact matrix printer. It is a multi-part form printer because it prints data on paper. This printer uses a hammer and a ribbon printer, that shapes pictures from dots. and other options are not correct, that can be described as follows:
- In option B, daisy-wheel printer prints data on printer only one side that's it is not correct.
- In option C, the Inkjet printer is capable to print data in multi-part forms, but this printer does not data in continuous forms.
- In option D, the color printer allows you to print data in color format like images, graphs, and banner. It prints data only on one side, that's why it is not correct.
The process of engineering typically starts with brainstorming.
