Answer:
Name of Operating System: Ubuntu
Five legal file names:
inventory.txt
total.txt
NIKKAH.txt
Defaulter.txt
studenT.txt
Five illegal file names:
wel/come.txt
..
MY>note.txt
.
my<work.yxt
Explanation:
To fix the illegal name:
1. Remove the special character, so it becomes welcome.txt
2. Remove the double dot and rename using text characters
3. Remove the special character, so it becomes MYnote.txt
4. A file cannot be named using dot. So we rename to a textual name
5. Remove the special character, so it becomes mywork.txt
Some additional rule for naming of files legally in Unix is that, you cannot use a reserved word to name your file. Starting a file name with number is allowed. Starting a file name with dot make the file to be hidden.
for count in range(5, 8):
print(count)
This will produce.

Complete Question:
Proxy servers and ACLs on network devices are examples of non-security devices with security features, while firewalls and IDS/IPS systems are the network's specialized security devices.
Group of answer choices:
A. True.
B. False.
Answer:
A. True.
Explanation:
A proxy server is an example of non-security devices with security features because it acts as a hub or gateway between a user and the internet. Therefore, when a user request for resources through a website, the proxy server acts as an intermediary between them and the web server providing such resources.
ACL is an acronym for access control list and it comprises of rules that grant or deny access to resources on a network.
A firewall is a network security system which prevents unauthorized access on a private network by monitoring, controlling and filtering inbound and outbound network traffic (packets) based on a set of security rules.
IDS and IPS are acronym for intrusion detection system and intrusion prevention system respectively. IDS is a security system which monitors the network traffic and notifies the engineer when there's a malicious activity. IPS is a security system which monitors the network traffic and blocks malicious activity as well as keeping logs.
<em>Hence, Proxy servers and ACLs on network devices are examples of non-security devices with security features, while firewalls and IDS/IPS systems are the network's specialized security devices. </em>
