Answer:
Memory.
Explanation:
When someone refers to "space" on a computer or device, they are usually referring to memory, which allows the user to save a file for future use, even after the computer has been turned off.
In Computer science, a memory is a term used to describe the available space or an electronic device that is typically used for the storage of data or any computer related information such as images, videos, texts, music, codes and folders. There are basically two (2) main types of memory;
1. Read only memory (ROM).
2. Random access memory (RAM).
Answer:
uses third party CAs to validate a user's identity
Explanation:
The Digital Certificate is the only means that technically and legally guarantees the identity of a person on the Internet. This is an essential requirement for institutions to offer secure services over the Internet. Further:
The digital certificate allows the electronic signature of documents The recipient of a signed document can be sure that it is the original and has not been tampered with and the author of the electronic signature cannot deny the authorship of this signature.
The digital certificate allows encryption of communications. Only the recipient of the information will be able to access its content.
Answer:
Explanation:
Using Python programming language
Explanation:
1. I defined a function add and passed in two parameters (a,b).
2. In the block of the function, I added the two numbers and printed the result.
3. I decided to use a function so that the program is re-usable and can accept various inputs.
Find the code below. (# are used for comments)
#Addition of numbers
def add(a,b):
print(a+b)
#Test Cases
add(2,4.5) #Result=6.5
add(10,290) #Result=300
add(2.567,4.58) #Result=7.147
Answer:
The correct answer is C) With respect to PERT and CPM, slack is the amount of time a task may be delayed without changing the overall project completion time.
Explanation:
The CPM (Critical Path Method) method is frequently used in the development and control of projects whose tasks have a fixed duration while the PERT (Program Evaluation and Review Techniques) method is a set of techniques with the same purpose but that allows to work with tasks with estimated probability duration but not deterministic.
Both methods are based on developing a complete scheme that includes all the tasks of a project linked to each other according to their sequence, determining the duration and analyzing different ways of reconfiguring the task planning to optimize the use of the resources of according to the general objectives of the project.
There are tasks that to start performing them must have been completed one or more previous tasks. The overall duration of the project is determined by the Critical Path, which is the sequence of tasks of greater duration. The tasks belonging to the critical path have to be carried out with special care because delays in them would cause delays in the total achievement of the project. That is why these tasks have no slack.
The rest of the tasks have some slack, which is determined by the time that a previous task can be delayed without delaying the total time of completion of the project, that is, not exceeding the duration determined by the critical path.
That is that why we say that the <em>slack</em><em> is the amount of time a task may be delayed without changing the overall project completion time</em>.
