Group of answer choices.
a. firewalls
b. access controls
c. proxy servers
d. All of the above
Answer:
d. All of the above
Explanation:
Cyber security can be defined as a preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.
Generally, redundancy to prevent unauthorized access can be implemented at a number of points throughout the security architecture, such as in firewalls, proxy servers and access controls.
A firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.
Generally, a firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access. It is a security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer.
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device.
They enable interoperability between software and hardware from different vendors.
Answer:
Yes, this statement is completely true
Explanation:
Yes, this statement is completely true. A personal computer is a multimedia machine and can be used to complete an incredibly large number of tasks with ease. Such tasks include all of the ones listed in the question. Aside from that other tasks depend more on the skill level and understanding of the user. For example, an individual who has a vast understanding of technology and programming can create software to perform absolutely any task they may want or need to do.
Answer:
Big Oh notation is used to asymptotically bound the growth of running time above and below the constant factor.
Big Oh notation is used to describe time complexity, execution time of an algorithm.
Big Oh describes the worst case to describe time complexity.
For the equation; T(N) = 10000*N + 0.00001*N^3.
To calculate first of all discard all th constants.
And therefore; worst case is the O(N^3).
