Answer:
<em>The systems development life cycle involves: 2, 1, 3, 4. That is the correct order.</em>
Explanation:
<em>The systems development life cycle involves: analysis, design, development and testing, implementation, documentation an evaluation, and maintenance</em>
<em>1. Analysis: involves analyzing end-user business requirement and refining project goals into defined functions and operations of the intended system.</em>
<em>2. Design: Involves describing the desired features and operations of the system.</em>
<em>3. Development and testing: involves establishing a high level plan of intended project and determining project goals.</em>
<em>4. Implementation/documentation/maintenance: The overall process for developing information systems from planning and analyisis through implementation and maitenance.</em>
Answer:
The answer is "Option a and Option f"
Explanation:
In the given question option a and option f is correct because both commands use the "cp" command, which is used to copy files and in this command, in option a, it uses the file "from cs250 to cs150", and an option "f" uses the "cs250 with '.h' that is a file extension", and the wrong choice can be defined as follows:
- In choice b, it is wrong because it is not a correct command.
- In choice c, in this command we use "?" symbol, that is wrong.
- In choice d and e both were invalid.
The correct answer is Network
Network is a layer of the OSI model that do the IP, ICMP, and ARP protocols operate.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given options to this question are:
-
resolution.
- magnification.
- orientation.
- colors.
The correct option to this question is 1. i.e.
Resolution.
The resolution of an image determines how many pixels per inch an image contains. Image having a higher resolution takes long page load times for a page and lower resolution takes less page load time. So, to prevent long page load times for pages containing images, it is best to use compressed file formation as well as appropriate image dimension and resolution.
While other options are not correct because:
Magnification, orientation, and color does not affect the page load time. Page load time for images only affected by the dimension and resolution of the images.
