Answer:
The main difference between second generation (2G) and third generation (3G) technology is data. 2G services were developed with mostly voice services in mind, but are capable of providing relatively slow (14.4kbps) speed data services.

Answer:
C. FIFO
Explanation:
The first-in, first-out (FIFO) page replacement algorithm is a low-overhead algorithm that requires work on the part of the operating system. On a page fault, the frame that has been in memory the longest is replaced.
Using FIFO algorithm implies that
a page which was brought into memory first will be removed first since variable was initialized very early. it is in the set of first in pages that will be removed.
It is the simplest page replacement algorithm. The operating system keeps track of all pages in the memory in a queue, the oldest page is in the front of the queue. When a page needs to be replaced page in the front of the queue is selected for removal that is first in first out.
A memory page containing a heavily used variable that was initialized very early and is in constant use is removed, then the page replacement algorithm used is called First In First Out.
Answer:
the world wide web is the substitute of the internet because the internet is connected to far for the world wide web
meaning of this : the world wide web (www) is the caption that you use to search and the internet is the one that connects to the www and is what is used to get on the www

Answer:
For the university accounting system that replaces an existing system the appropriate generic software process model is Waterfall model
This is because the requirement of the system can be predicted in advance because of the existing system and secondly, this a mission critical system and the requirement are stable and reusable
For the interactive travel planning system that helps users plan journeys with the lowest environmental impact the appropriate generic software process model is Prototype Model
This is because the user's requirement may likely change and fast delivery is essential to be implemented and for this the prototype model can save time of development to focus on essential functions first.
Explanation:
In order to get a better understanding of the answers above let define the concept of
Waterfall Model:
We can define waterfall model as a type of software development approach that explains step by step development method, this software development approach consist of five to seven steps and each step is characterized by different tasks and objectives and these steps combined together explains the the life cycle of the the software development process.
Prototype Model
We can define prototype model as a type of system development approach whereby an estimation(i.e the prototype) of the final system is constructed,tested and adjusted until the desired result is obtained and the the main system is then constructed with the specification of the perfect estimation or prototype for example when constructing a bridge the engineer apply this methodology by first constructing an estimation or prototype of what the bridge should look like and then various test and adjustments are been carried out on this prototype bridge afterward he main bridge is been constructed with the specification of the prototype.
