<span>C. Maintenance
is an important practice can help prevent hardware trouble. Maintenance involves operational and
functional checks, servicing, repairing or replacing if necessary. Maintenance has
two types which are </span>preventive
or scheduled maintenance and corrective maintenance. Inspecting, maintaining
and protecting a device, equipment or facilities before breaking down or other
problems occur it is called preventive while corrective is when it is repaired
or replaced after wear, malfunction or break down.
Oh we did this in class I know this
In decimal it is:
0*8^0 + 7*8^1 + 4*8^2 + 2*8^3 = 1336
Basically adding up the place values.
Answer:
<em>Empirical technical </em>research has a fundamental objective, which is to provide objective and independent information on the quality of the product to the interested party or stakeholder. It is one more activity in the quality control process.
Explanation:
Testing is basically a set of activities within software development. Depending on the type of tests, these activities may be implemented at any time during said development process. There are different software development models, as well as test models. Each one has a different level of involvement in development activities.
In a full penetration testing process, there are pre-instances to run this tool, but to take the first steps it is probably the best way to start. Nmap is a network scanning tool that allows you to identify what services are running on a remote device, as well as the identification of active computers, operating systems on the remote computer, existence of filters or firewalls, among others.
In simple words, when a server or device is going to be attacked, the attacker can carry out different attacks depending on the service: it is not the same to damage a web server, a database server or a perimeter router. Therefore, in any deployment, the first step will be to identify the services in the infrastructure, to decide how to proceed and, considering that in a penetration test the steps of an attacker are “imitated”, it will also be started in the same way.
Answer: D) components are instances of abstraction
Explanation:
As, implicit invocation is the process by which it is used by the the software designer for styling the architecture of the software,where the event handling structured are formed in the system. The main aim of the implicit invocation is to separated the conceptual concern for maintaining or improving the ability of the software engineer. It is basically based on the notion of the broadcasting and based on the event driven. The components are the instance of the abstraction which are not used as the components in implicit invocation which are relinquished control the system over the computational performance,this is the major disadvantage of the implicit invocation.
