1. Ping

Introduction

The network program was operated with the program version of Pycharm 2019.3.1 (professional edition)

Algorithm:

1. Initiate
2. Network commands test application is opened in a Window.
3. Go to ping address for entering address and select option
4. The command receives address from the program.
5. The address is received by destination
6. If the site is valid
7. Destination sends 4 data packets with verification notification to the command
8. OK signal is send by command to ping the program
9. After that, the users receives four data packets
10. Else
11. Down notification is send by the command in the console program
12. No reply message is received by actor
13. Stop

• Ipconfig/all

Introduction

Pycharm 2019.3.1 was the version of program was used for the program on networking.

Algorithm

1. Initiate
2. Networking Command Test Application open
3. The option Ipconfig/all is choose
4.  Console program request for program
5. Router receives the request command
6. If there is right connection,
7. The command prompt receives all the IP addresses like MAC, DNS and DHCP address
8. The information is provided by command to console program
9. The user view the configuration information displayed by the console
10. If not,
11. Connection down status notification is send by the command to console
12. And no reply message is received by actor
13. End

Individual project

Week 1

I’m reaching why the GP patient’s data record essential, because the doctor needs to look at the patient illness history and medication record to help the doctor to identify, which types of prescription to give to the patient.

Ingeneral, the patient data used to improving health care services, develop new medication and prevent the disease.

Week 2

In this week my reach will focus on the GP petient data security policy (the minimum requirement to protect the patient data to earn the patient trust) such as

login passoword

Encription data

Antivirus

backup data and the system updated

Also consider latest network hardware such as routes, or firewall implement the security command to reduce the risk of the malicious attack.

Week 3

I watched on you tube data protection training video by ICO, data day hygiene. They are strongly advise do not used memory stick to stored personal data , because it is easy to lost or misused unless the memory stick encrypted.

Also send personal data by fax without checking if the number was correct very high risk as well.

When you are sharing personal information with other organization must only information relevant the purpose and content should be disclosed.

furthermore, whey are explain how to dispose the personal information should be measured by appropriate technical, because If you are just deleted the hard drive that is not proper way and the data can be retrieve.

Week 4

Group project;

We had group project meeting during the session. the meeting focus individual task in the group project and we are scheduled time to handed individual task.

Individual project

Week 5

We had group project discuss the report tiles and setup Microsoft team to able to communicate essay 10 March 202
