<h3>How is the conversion done?</h3>

In Conversion from hex to denary via binary:

One has to Separate the hex digits to be able to know or find its equivalent in binary, and then the person will then put them back together.

Example - Find out the denary value of hex value 2D.

It will be:

2 = 0010

D = 1101

Put them them together and then you will have:

00101101

Which is known to be:

Write the SQL statements that define the relational schema (tables)for this database. Assume that person_id, play_id, birth_year
Sunny_sXe [5.5K]

Answer:

  • SQL statement that defines table for Actor

CREATE TABLE Actor(

person_id integer primary key,

name varchar2(40) not null,

birth_year integer check ((birth_year) <= 2019)

);

  • SQL statement that defines table for Play

CREATE TABLE Play(

play_id integer primary key,

title varchar2(60) not null,

author varchar2(60) not null,

year_written integer check ((year_written) <= 2019)

);

  • SQL statement that defines table for Role

CREATE TABLE Role (

person_id integer,

character_name varchar2(60) not null,

play_id integer,

constraint fk_person foreign key (person_id) references actor(person_id),

constraint fk_play foreign key (play_id) references play(play_id),

primary key (person_id, character_name, play_id)

);

Explanation:

Other information that were not added to the question are as below:

The following database contains information about three tables i.e. actors, plays, and roles they performed.

Actor (person_id, name, birth_year)

Play (play_id, title, author, year_written)

Role (person_id, character_name, play_id)

Where: Actor is a table of actors, their names, and the year they were born. Each actor has a unique person_id, which is a key.

Play is a table of plays, giving the title, author, and year written for each play. Each play has a unique play_id, which is a key.

Role records which actors have performed which roles (characters) in which plays.

Attributes person_id and play_id are foreign keys to Actor and Play respectively.

All three attributes make up the key since it is possible for a single actor to play more than one character in the same play

Further Explanation:

In SQL, in order to define relational schema (Tables) for a database, we use CREATE TABLE statement to create a new table in a database.  The column parameters specify the names of the columns of the table.  The datatype parameter specifies the type of data the column can hold (varchar, integer, date)

Describe what a layer 3 router is and what are its advantages and drawbacks compared to other network devices.
Oduvanchick [21]

Answer:

Did you mean layer 3 switch? Because a router always operates at layer 3

Explanation:

If the answer is yes, then a layer 3 is a switch that combines the functions of a switch and a router. So it is capable of operate layer 2 and layer 3. Some of its benefits are: Support routing between VLAN, decrease network latency because the packets don’t have to make extra hops to go through a router and reduce security management. But they are really expensive and lack of WAN functionality so they are used mostly for large intranet environments.
