Explanation:
Web development is the creation of web pages. It requires standard web development tools like HTML, CSS and JavaScript.
The web page is made up of the header, the body and footer, which are all inside a html file. On the header, body and footer tags must be contained within a html opening and closing tags.

Answer:
Database engine.
Explanation:
The database engine is one of the components of the database management system and its main function is to allow for storage of data, manipulation of data and retrieval of data. it is also responsible for the processing and security of data. It is sometimes called the heart of the database management system.
Other components of the database management system, among others, are;
i. Query processors for transforming queries into low level instructions.
ii. Data manager for handling data error and recovery
iii. Data which is the main component of the database management system on which operations are done. If there were no data there would be no database management system.
Answer:
a) Yes
b) Yes
c) Yes
d) No
e) Yes
f) No
Explanation:
a) All single-bit errors are caught by Cyclic Redundancy Check (CRC) and it produces 100 % of error detection.
b) All double-bit errors for any reasonably long message are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
c) 5 isolated bit errors are not caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit since CRC may not be able to catch all even numbers of isolated bit errors so it is not even.
It produces nearly 100 % of error detection.
d) All even numbers of isolated bit errors may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
e) All burst errors with burst lengths less than or equal to 32 are caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit. It also produces 100 % of error detection.
f) A burst error with burst length greater than 32 may not be caught by Cyclic Redundancy Check (CRC) during the transmission of 1024 bit.
Cyclic Redundancy Check (CRC) does not detect the length of error burst which is greater than or equal to r bits.
