The main advantage of using the Gray code is:

zzz [600]

Answer:

a) only one digit changes as the number increases.

Explanation:

Let us first understand what does it mean when we say only one digit changes as the number increases using the Reflected Binary code (also called Gray code)

consider the 4 bit representation of Binary coded decimal and RB codes

Decimal | Binary code | Reflected binary (RB) code

0 0000 0000

1 0001 0001

2 0010 0011

3 0011 0010

4 0100 0110

5 0101 0111

As you can see in the case of binary codes, there are more than one digit changes between two consecutive numbers.

But notice that in the case of Gray codes, there is always one digit change between two consecutive numbers.

The problem with the binary codes is that the more digits change there states the greater is the chance of ending up with random transitional values rather than real values which can be incorrect. The RB code solves this problem by only changing one digit at a time.

The RB code is widely used in linear and rotary encoders, error correction and digital logic design.

What is the output of the following code? ArrayList list = new ArrayList(); java.util.Date d = new java.util.Date(); list.add(d)

harina [27]

Answer:

true true

Explanation:

The code snippet first declare an arraylist called list. Then, a date object d is created. The object d is added to the arraylist twice.

Then inside the display statement, there are two boolean expressions. They both check if the element in index 0 and index 1 of the arraylist are the same and if they refer to the same object location in the memory.

The object in index 0 and index 1 are the same and they refer to the same object location in the memory hence the output is true true.

Readme [11.4K]

Answer:

a. Install a web application firewall.

Explanation:

In this scenario, an organization is building a new customer services team, and the manager needs to keep the team focused on customer issues and minimize distractions. The users (employees) are provided with a specific set of tools (software applications) installed, which they must use to perform their duties. However, other tools (software applications) are not permitted for compliance and tracking purposes of employees who flouted the rules made by the management. Also, team members are able to access the internet for purposes such as, product lookups and to research customer issues.

In order to keep the team focused on customer issues and minimize distractions, the security engineer should install a web application firewall.

A web application firewall is an application firewall that can be used for monitoring, filtering, blocking or denial of bidirectional packets (http traffics); to and from websites or web applications.

When a web application firewall is properly implemented and configured by the security engineer, it inspects all http traffics and provides adequate protection against cookie poisoning, security misconfigurations, SQL injection, broken authentication, cross-site scripting (XSS), file inclusion, sensitive data leaks, buffer overflow etc.

Basically, the web application firewall primarily prevents an application layer (layer 7 of the OSI model) attacks.

Hence, to fulfil the manager's requirements, the security engineer should install a web application firewall which basically works as a reverse proxy protecting the web server from vulnerabilities or potential attacks.

If name is a String instance variable, average is a double instance variable, and numOfStudents is a static int variable, why wo

IRINA_888 [86]

Answer:

Explanation:

Based solely on the snippet of code provided on the question the main reason why the code won't compile (from the options provided) is that the setAverage() method can’t access the average instance variable. Since the average variable is an instance variable it means that it only exists inside the one of the functions and not to the entire class. Meaning that in this scenario it can only be accessed by the Student function and once that function finishes it no longer exists. Also, it is not one of the options but if these variables are instance variables as mentioned their type needs to be defined inside the function.
