What Common Design Feature Among Instant Messaging7 min readReading Time: 5 minutes
Instant messaging (IM) is a form of online communication that allows two or more people to communicate in real-time. It differs from other forms of online communication, such as email, in that messages are sent and received almost immediately.
One of the most common features among instant messaging platforms is the ability to send and receive messages in real-time. This means that as soon as a message is sent, it is delivered to the other person’s device, and they can start typing a response immediately.
Another common feature among IM platforms is the ability to send files. This allows users to send photos, documents, and other files to one another.
Many platforms also allow users to make voice and video calls. This allows people to have face-to-face conversations with one another, just as they would if they were in the same room.
Finally, many platforms allow users to chat in groups. This allows people to have conversations with multiple people at the same time.

Which area of focus helps identify weak network architecture or design?
When it comes to network architecture or design, there are a few key areas that can help identify weak spots. These include the network’s topology, its protocols and the devices that are being used.
Topology is the way in which a network is physically laid out. This can affect performance and security, as well as how easy it is to troubleshoot and expand. A network with a bus topology, for example, is more vulnerable to attacks than one with a star topology, since all devices are connected to a central point.
Protocols are the rules that govern how data is transmitted over a network. A network that uses a outdated or insecure protocol, for example, is more vulnerable to attack. Similarly, a network that is running too many protocols at once can be difficult to manage and may not be performing as well as it could be.
Finally, the devices that are being used can also affect the strength of a network. Older devices, for example, may not have the same security features as newer devices. In addition, devices that are not compatible with each other can cause problems with network performance.
Which of the following happens by default when you create and apply a new ACL on a router?
When you create and apply a new ACL on a router, the following by default happens:
– The ACL is applied to incoming packets
– The ACL is applied in the order that it is configured
– The ACL is a permit-all ACL
Which of the following items would be implemented at the network layer of the security model?
There are many items that can be implemented at the network layer of the security model. This includes but is not limited to firewalls, intrusion detection systems, and virtual private networks.
Firewalls are a key part of the network security model. They are used to block unauthorized access to network resources. Firewalls can be used to protect an entire network or individual hosts on the network.
Intrusion detection systems are another key part of the network security model. They are used to detect and report malicious activity on the network. Intrusion detection systems can be used to protect an entire network or individual hosts on the network.
Virtual private networks are another key part of the network security model. They are used to create a secure connection between two or more networks. Virtual private networks can be used to protect an entire network or individual hosts on the network.
Which of the following types of proxies would you use to remain anonymous when surfing the internet?
There are a variety of different types of proxies that can be used to remain anonymous when surfing the internet. The most popular types of proxies are HTTP and SOCKS proxies.
HTTP proxies are the most common type of proxy. They are easy to use and are usually free. However, they are not very secure and can be easily detected.
SOCKS proxies are more secure than HTTP proxies and are harder to detect. However, they are not as easy to use as HTTP proxies.
Another option is to use a VPN. VPNs are more secure than both HTTP and SOCKS proxies and are harder to detect. They are also more expensive than HTTP and SOCKS proxies.
Which common design feature among instant messaging clients make them less secure?
Instant messaging (IM) clients are used to communicate with others in real time. They have become increasingly popular in recent years, but many of them suffer from a common design flaw that makes them less secure.
One of the main reasons that IM clients are less secure is that they often allow users to share their contact information with others. This can be a major security risk, as it allows others to easily contact them outside of the IM client.
Another common design flaw among IM clients is that they often allow users to share files with others. This can also be a major security risk, as it allows others to access sensitive files on your computer.
Finally, many IM clients allow users to send messages to multiple people at the same time. This can be a major security risk, as it allows others to see your messages if they are monitoring your chat session.
Fortunately, there are a few steps that you can take to make your IM client more secure. One of the best things you can do is to use a password to protect your chat sessions. This will help to prevent others from accessing your chat logs without your permission.
You can also use a tool like HTTPS Everywhere to encrypt your traffic. This will help to keep your communications safe from prying eyes.
Finally, be careful about the files that you share with others. Only share files that you trust and that are not sensitive in nature.
By following these tips, you can help to keep your IM client more secure and protect your communications from unauthorized access.
What is the most common network architecture?
When it comes to computer networks, there are a few different topologies or architectures that are used more commonly than others. The three most common network architectures are the bus, star, and mesh topologies.
The bus topology is the simplest of the three and is made up of a single cable or “bus” that all the devices on the network are connected to. The devices on the bus share the same bandwidth and if one device is hogging all the bandwidth, the other devices on the bus will suffer. This is the most common topology for small home networks.
The star topology is made up of a central device, often called a “hub”, that all the other devices on the network are connected to. The hub acts as a traffic controller and ensures that all the data packets sent between devices arrive at their destination. This is the most common topology for larger networks.
The mesh topology is the most complex of the three and is made up of a mesh of interconnected devices. This topology is often used in situations where there is a high level of network traffic or where there is a need for redundancy, meaning that if one device fails, another can take its place.
What is a common use of an access control list?
An access control list (ACL) is a list of permissions that can be assigned to individual users or groups. This can be used to restrict access to certain areas of a network or to specific files or folders.
One common use of an ACL is to allow or deny access to resources based on the user’s role or position within the organization. For example, a manager may be given access to all files and folders within the company, while a secretary may be given access to only specific files and folders.
ACLs can also be used to restrict access to sensitive data. For example, a company may store customer credit card information in a secure folder that is only accessible to employees with the necessary permissions.
ACLs can be implemented in a number of different ways, depending on the operating system and networking hardware used. In a Windows network, for example, ACLs can be configured on individual files and folders, or on the entire network.
ACLs can be a powerful tool for managing access to resources on a network. They can help to ensure that only authorized users have access to sensitive data and that employees have access to the resources they need to do their job.
