Assume that processor refers to an object that provides a void method named process that takes no arguments. As it happens, the

process method may throw one of several exceptions. Write some code that invokes the process method provided by the object associated with processor and arrange matters so that your code causes any exception thrown by process to be ignored. Hint: use the catch (Exception ex) and do nothing under the catch clause.

Answer:

Following are the code to the given question:

try//defining a try block

{

processor.process();//defining an object processor that calls process method

}

catch(Exception e)//defining a catch block

{

}

Explanation:

In this question, the 'Try' and 'catch' block is used in which both the keywords are used to represent exceptions managed during runtime due to information or code errors. This try box was its code block which includes errors. A message queue catches the block errors and examines these.

In the try block, a method "process" is used which is create the object processor that calls the method.

Give two reasons why network security is the most important issue regarding data centers.
deff fn [24]
Three key concepts of security are integrity, confidentiality, and availability.

Network firewalls are the first line of defense, intended to keep intruders out. Once a system is compromised, all of its data can be accessed, and if a bad actor gains access to one system, they effectively have access to all of the systems. This touches on both system integrity and data confidentiality.

Security is also related to availability, or uptime. If your network is compromised, it may be inaccessible to those who need to use it, making it useless. If I'm working from an office in Chicago, and the company's main DC is in Atlanta, I need the network to remain available to access critical files.

Communication protocols, sets of rules agreed to by all parties, are designed in order to:
mote1985 [20]

Group of answer choices.

A. Ensure that cell phones and laptops cannot communicate.

B. Give each country its own internet language.

C. Ensure that new technologies and devices that haven't been invented yet can all use the same methods of communication.

D. Assure that computers and other devices don't pollute the environment.

Answer:

C. Ensure that new technologies and devices that haven't been invented yet can all use the same methods of communication.

Explanation:

OSI model stands for Open Systems Interconnection. The seven layers of OSI model architecture starts from the Hardware Layers (Layers in Hardware Systems) to Software Layers (Layers in Software Systems) and includes the following;

1. Physical Layer

2. Data link Layer

3. Network Layer

4. Transport Layer

5. Session Layer

6. Presentation Layer

7. Application Layer

Each layer has its unique functionality which is responsible for the proper functioning of the communication services.

Additionally, a standard framework for the transmission of informations on the internet, it is known as the internet protocol suite or Transmission Control Protocol and Internet Protocol (TCP/IP) model. One of the very basic rule of the TCP/IP protocol for the transmission of information is that, informations are subdivided or broken down at the transport layer, into small chunks called packets rather than as a whole.

Hence, communication protocols, sets of rules agreed to by all parties, are designed in order to ensure that new technologies and devices that haven't been invented yet can all use the same methods of communication.

This ultimately implies, there exist standard frameworks and protocols that are designed and developed to serve pre-existing technologies and devices, as well as those that would be invented in the future.

For example, SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services on an internet-enabled device.
