How many different values can a bit have?
Detalles de la respuesta
A bit is the smallest unit of digital information in computing, and it can have two possible values: 0 or 1. This is because a bit is used to represent a binary digit, which can be either on or off, true or false, or high or low. So, the answer is 2. To give an example, imagine a light switch that can either be turned on or off. We can use a bit to represent the state of the switch, where 0 represents the switch being off, and 1 represents the switch being on. In this case, a single bit is enough to represent the two possible states of the switch. Similarly, in computing, a single bit is enough to represent two possible states of any digital information.

What is the function of firewall?
Detalles de la respuesta
A firewall is a type of cybersecurity tool that helps protect a computer or network from unauthorized access or malicious activity from the internet. Think of a firewall as a security guard that stands at the entrance to your network, examining all incoming and outgoing traffic. It examines each packet of data to see if it meets certain criteria, such as the source and destination of the data, and the type of data being transmitted. If the packet meets the criteria, it's allowed to pass through the firewall and reach its destination. If it doesn't meet the criteria, the firewall blocks the packet, preventing it from entering your network. A firewall can help prevent attacks like hacking, malware infections, and other cyber threats that could compromise your data or network. Firewalls can also be configured to filter out certain types of traffic or limit access to certain resources, providing an additional layer of protection for your network. In summary, a firewall is a vital cybersecurity tool that acts as a barrier between your network and the internet, helping to keep your data and devices safe from cyber threats.

In which situation does running application remain active?
Detalles de la respuesta
When a computer application is running, it is stored in the computer's memory, which allows it to continue functioning as long as it is needed. In the case of logging off, shutting down, or rebooting the computer, all applications currently running on the system are closed or terminated. Therefore, the running application would not remain active in any of these situations. However, in the case of a user switching, the running application can remain active. This is because when a user switches on a computer that is running, the operating system creates a new user session while keeping the current user's session active. In this scenario, the running application would continue to function within the current user's session, while the new user session would be independent and have its own set of applications and processes. Therefore, the running application would remain active when the user is switched.
