If I were the manager of the branch, I would consider the following specific components of Information System (IS):

1. Hardware: I would assess the hardware components of the computers being used by the tellers and staff members. This would include checking if the computers are functioning properly, if there are any connectivity issues with the central bank system, and if any hardware upgrades or replacements are required.

2. Software: I would evaluate the software being used on the computers. This would involve checking if the operating systems and applications are up to date, if there are any compatibility issues with the central bank system, and if any software updates or patches are needed.

3. Network: I would examine the network infrastructure of the branch. This would involve checking if the local area network (LAN) is properly configured, if there are any issues with network connectivity, and if the branch’s network is able to establish a connection with the central bank system.

4. Connectivity: I would investigate the connectivity options available to the branch. This would include checking if the branch has a stable internet connection, if there are any issues with the internet service provider, and if the branch’s network is able to establish a secure connection with the central bank system.

5. Security: I would assess the security measures in place to protect the branch’s computers and network. This would involve checking if there are any security breaches or vulnerabilities that could be causing the connection issue, and if any additional security measures need to be implemented to ensure a secure connection with the central bank system.

By considering these specific components of Information System, I would be able to identify the root cause of the connectivity problem and provide a legitimate and sustainable solution to ensure that the computers in the branch can successfully connect to the central bank system of Bank 2.
