It is a class B network, so for a class B network, the upper 16 bits form the network address and the lower 16 bits are subnet and host fields. Of the lower 16 bits, most significant 4 bits are 1111. This leaves 12 bits for the host number. So, 4096(2^12) host address exists. First and last address are special so the maximum number of address is 4096-2=4094.

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.
JPEG is a file format for an image that will be compressed. Since it compressed the file size will be much smaller. That makes JPEG is one of the most used file types for images and was a default format for many application. But the drawback of compressing an image is that a portion of the data will lose and will cause the image quality dropped or produce a noise.
