Check the explanation
Explanation:
Given a collection SS of subsets of a set X, an exact cover of X is a subcollection S∗S∗ of SS that satisfies two conditions:
- The intersection of any two distinct subsets in S∗S∗ is empty, i.e., the subsets in S∗S∗ are pairwise disjoint. In other words, each element in X. is contained in at most one subset in S∗S∗.
- The union of the subsets in S∗S∗ is X, i.e., the subsets in S∗S∗ cover X. In other words, each element in XX is contained in at least one subset in S∗S∗.
XX is the collection of letters on the refrigerator.
SS is the collection of words that your daughter knows that are made up of letters in X.
S∗S∗ is a subcollection of words from SS that exactly cover X.

Answer:
TRUE
Explanation:
Intrusion Detection System (IDS) monitors policy violations or malicious activities in a system or network. It could be a device or a software application.
IDS differs according to the size of the network. There are two main classifications: Host-based Intrusion Detection System (HIDS) and Network Intrusion Detection System (NIDS). HIDS observes important Operating System (OS) files. While the NIDS analyses network traffic, they are placed at a unique point or several unique points to monitor outgoing and incoming traffic within the network.
Hence it tries to identify unique sequences appearing across several packets in a traffic stream than in individual packets.
Explanation:
Both perform almost the same function of storing data, performing numerical calculations, formating cells, and to generate reports.
However, when dealing with data that is short term (requiring less updating) Microsoft Excel is recommended as it provides easy spreadsheet functions. Access on the other hand is a more complex application for data analysis involving constantly changing data values that are long term based. Access allows for efficient data analysis using complex tools such as import module, automated queries etc.
