Answer:
Boot Sector virus is when a virus infects the Boot Sector of a hard disk. A Boot Sector is the initial files necessary to start an OS and other bootable programs. It is typically infected by these viruses when started with infected floppy disks, however the boot virus does not have to be successful to infect your computer. Once infected, the virus tries to infect every other disk.

Answer:
=SUM(Range value)
like =SUM(A1:A7) or =SUM(A1:H1)
Explanation:
We need to make use of the SUM function, and then we need to mention the cells or range value that references a series of cells row-wise or column-wise. Like a range value of A1:A7 means A1,A2,A3,A4,A5,A6,A7 and the range value of A1:H1 means A1, B1,C1,D1,E1,F1,G1,H1. And similarly, you can represent various cells depending upon the code you come up it, and finally, you need to sum them all using the SUM function.
Answer:
There are multiple critical paths
Explanation:
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. It is commonly used in conjunction with the program evaluation and review technique (PERT). A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish.
The essential technique for using CPM is to construct a model of the project that includes the following:
- A list of all activities required to complete the project (typically categorized within a work breakdown structure),
- The time (duration) that each activity will take to complete,
- The dependencies between the activities and,
- Logical end points such as milestones or deliverable items.
Using these values, CPM calculates the longest path of planned activities to logical end points or to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer).
considering the above function of the cpm analysis because you have multiple path, there is tendency that more than path through the project network will have zero slack values.
<u>Answer:</u>
Domain names serve to identify Internet resources, such as computers, networks, and services, with a text-based label that is easier to memorize than the numerical addresses used in the Internet protocols. A domain name may represent entire collections of such resources or individual instances.
