Answer:
B. Have the user press the appropriate function key combination to enable the wireless radio and then attempt to connect to the wireless network.
Explanation:
Every more often than not, users may experience wireless connection problems. How they respond to these issues solely depends on various factors. When a user like this has issues connecting to the network, first on the list of proper troubleshooting procedures is to check whether the wireless adapter or the function key that turns the wireless radio connection on is toggled on. Sometimes the most obvious causes are the hardest to see. The user should check this first because it will save him or her lots of troubleshooting time if the switch was simply physically disabled.
Answer:
The process of converting information, such as text, numbers, photos, or music, into digital data that can be manipulated by electronic devices is called Digitization
Explanation:
It is the process of converting “information in to a digital form”. Here the information are organized into bits. Mostly these data will be converted into the form of image. But these can be edited by converting once again into necessary format and even back to image too. There are specific tools which the user needs to install for editing the digital documents.
The reason why we need digitization is that
a) We want to convert hard copy into soft copy and store it in system.
b) We would like to edit the data in the hard copy and preserve as a fresh copy.
Answer:
Incremental method.
Explanation:
Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.
An incremental model refers to the process in which the requirements or criteria of the software development is divided into many standalone modules until the program is completed.
Hence, an incremental method typically involves developing a system through repeated cycles and smaller portions at a time, enhancing and evolving the system over time.
In SDLC, a waterfall model can be defined as a process which involves sequentially breaking the software development into linear phases. Thus, the development phase takes a downward flow like a waterfall and as such each phase must be completed before starting another without any overlap in the process.
Also, a spiral model can be defined as an evolutionary SDLC that is risk-driven in nature and typically comprises of both an iterative and a waterfall model. Spiral model of SDLC consist of these phases; planning, risk analysis, engineering and evaluation.
