Answer 1 it’s online banking
Answer:
A. Define boundaries
C. Deny access
D. Delay access
Explanation:
A barrier is a material or structure used to prevent or block access. Barriers can either be natural or structural and are used for many purposes usually for security reasons. The following are functions of barriers either natural or structural:
- Define areas of boundaries
- Delay or slow access. Example is the use of speed bumps to slow down vehicles.
- Provide access to entrances such as the use of gates
- Deny access to unauthorized personnel and allowing authorized personnel.

Explanation:
The adjacency matrix is the matrix that has nodes as rows and columns. The nodes if connected is stated as 1 or else 0. And the adjacency list representation is the list with nodes and connected nodes. The nodes that are not connected are not being listed. The diagram and list as well as matrix can be found in the attachment.
This is a tough question. I’m not sure if I’ll get it right but I’ll try.
Data structures used for file directories typically have a hierarchical tree structure, referred to as a directory structure. The tree has a root directory, and every file in that system has a unique path.
The simplest method of implementing a directory is to use a linear list of file names with pointers to the data blocks. But another way that you can format a file directory is by using a hash table. With this method, the linear list stores the directory entries, but a hash data structure is also used. The hash table takes a value computed from the file name and return the pointer to the file name any linear list.
So I think it’s C. But I’m not 100% sure.
I hope that helps.
