Some scientists hypothesize that Earth's ozone layer is being damaged by the emission of certain chemical compounds known as ozone-depleting substances (ODS), such as chlorofluorocarbons (CFCs).
b. chlorofluorocarbonsWhat are ozone-depleting substances (ODS)?These substances have been widely used in various industrial processes, aerosol propellants, refrigerants, and fire suppression systems. When released into the atmosphere,
CFCs can reach the stratosphere and interact with ozone molecules, leading to their depletion and thinning of the ozone layer. Ultraviolet radiation is a consequence of ozone layer depletion, and global warming, while impacting the Earth's climate, is not directly linked to ozone layer damage.
Plant life on Earth plays a vital role in oxygen production and carbon dioxide absorption but is not a direct cause of ozone layer depletion.

f $500 million. You're on the phone with the manager of software development who has made a request to hire a notorious white hat hacker to probe your company's software products in an attempt to identify any vulnerabilities. The reasoning is that if anyone can find a vulnerability in your software, she can. This will give your firm a head start on developing patches to fix the problems before anyone can exploit them. You feel uneasy about hiring people with criminal records and connections to unsavory members of the hacker/cracker community and are unsure if you should approve the hire. What is the difference between a black hat hacker and a white hat hacker
Answers
Answer:
Whereas a black hat hacker gains access into a software or system product in order to exploit its weaknesses for selfish purposes, a white hat hacker is a professional who finds and fixes system security issues for the welfare of the entity.
Explanation:
Black-hat hackers, who exploit system weaknesses for selfish purposes, rely on the use of viruses, malware, and spyware to gain access into an entity's database. Their intentions are always malicious and criminal in nature. They are not like white hat hackers who try to identify weaknesses in a system before black hat hackers could do the same.
If distances are recorded as 4-bit numbers in a 500-router network, and distance vectors are exchanged 3 times/second, how much total bandwidth (in bps) is used by the distributed routing algorithm
Answers
Answer:
A total of 6,000 bps of bandwidth is used by the distributed routing algorithm
Explanation:
This is a bandwidth requirement question.
We proceed as follows;
To calculate the total number of bits for a routing table, we use the following formula;
Routing table=Number of routers * length of cost
we are given the following parameters from the question;
Number of routers = 500
length of cost = 4 bits
Routing table = 500*4
=2000
Hence, a routing table is 2000 bits in length.
Now we proceed to calculate the bandwidth required on each line using the formula below;
Bandwidth = no.of seconds * no.of bits in routing table
Bandwidth required on each line = 3*2000
=6000

A database designer wants to create three tables: Supplier, Product, and Country. The Supplier table has a Countryld column with values that must appear in the Country table's Countryld column. The Product table has an auto-increment column.
Which table's CREATE TABLE statement(s) must specify a FOREIGN KEY?
a. Supplier
b. Product
c. Country
d. Supplier and Country
Answers
Answer:
(a) Supplier
Explanation:
In database design, two tables are linked together using a FOREIGN KEY. A foreign key is formed from one or more columns of one table that reference or match another key (often called a primary key) in another table. In other words, when a column or a combination of columns on one table points to a primary key of another table, the column(s) will specify the foreign key.
PS: A primary key is used to make each entry of a table unique.
In the given tables - Supplier, Product, Country - since the Supplier table has a column called CountryId referencing the CountryId column of the Country table, then CountryId is a primary key in Country table but a foreign key in Supplier table.
Therefore, the CREATE TABLE statement(s) of the Supplier table must specify a foreign key.
A database management system often reads and writes data in a database, and makes sure there is consistency and availability. The supplier table's CREATE TABLE statement(s) must specify a FOREIGN KEY.
The database system often guards data when a lot of transactions is taking place. it often hinders multiple transactions with the same data at the same time.The Select SQL statement does not alter any database data. A supplier database is made up of different list of service, product or materials providers who can meet orders quickly.
