Network topology is the arrangement of the elements of a communication network. Network topology can be used to define or describe the arrangement of various types of telecommunication networks, including command and control radio networks, industrial fieldbusses and computer networks.
Advantages:
It is easy to handle and implement.
It is best suited for small networks.
Disadvantages:
The cable length is limited. This limits the number of stations that can be connected.
This network topology can perform well only for a limited number of nodes.
Answer:
D. Spreadsheets
Explanation:
While A also seems correct, a spreadsheet is best at collecting and organizing data. Databases would only store data while a spreadsheet would keep those records, as well as help calculate a budget or payroll.
Answer:
The complete program is as follows:
m_str = input('Input m: ')
mass = float(m_str)
e = mass * 300000000**2
print("e = ",e)
Explanation:
This is an unchanged part of the program
m_str = input('Input m: ')
This converts m_str to float
mass = float(m_str)
This calculates the energy, e
e = mass * 300000000**2
This is an unchanged part of the program
print("e = ",e)
Answer:
Explained
Explanation:
Yes, I agree that digital signatures are the best way to protect the data in the date in question. A digital signature is mathematical technique used to validate the authenticity and integrity of a massage. Digital signature is far more inherent security. It is built to solve problems of tempering and impersonation of digital documents. It allows the authorized user to have authentic right, and the unauthorized person is denied access.
Answer: keeps confidential documents secure,
displays a GUI, allocates the computer's resources, and retrieves files
Explanation:
The operating system can be defined as the software installed in the system that provides the information and services to the users by controlling the hardware, software resources, and regulates the computer programs. It runs the applications and programs in the system, displays the graphic user interface for the services, stores, manipulates, and retrieves files. It prevents the unauthorized access to the data and programs by using passwords thus provides the security to the system and documents.
