Answer:a) Mainframes, miniframes, PCs, desktop Internet computing, mobile computing
Explanation: The hierarchy of the computers or computing are in the generation is:-
- Mainframe:-designed for the execution of huge data processing , storage and execution.
- Miniframe:-has similar functioning as the mainframe but on smaller scale and version.
- Personal computer(PC):-It is designed for the individual purpose and according the need of the user.
- Mobile computing:-computing that can be done on the mobile phone similar to the computing on the personal computer
- Internet computing:-the computing of the mobile and computer system with the facility of the internet connectivity.
Answer:
The correct answer for the following question is VLAN.
Explanation:
It stands for Virtue Logical Area Network which allows you to group port on a switch logically. VLANs can be extend across (a period of time) multiple switches means you used to express on port that you're in that VLAN by changing the VLAN number.
We have the ability to improve our security with VLANs by controlling what VLAN is accessing with the other network of VLANs. So that this network is particularly helpful in office situation to create subdomain without wiring physical domain as your network.
Answer:
Option d is the correct answer for the above question.
Explanation:
- The first loop of the program has a second loop and then the statement. In this scenario, the second loop executes for the value of the first loop and the statement executes for the value of the second loop.
- The first loop executes 4 times, Then the second loop or inner loop executes n times for the n iteration of the first loop, for example, 1 time for the first iteration of the first loop, 2 times for the second iteration of the first loop and so on.
- Then the inner loop executes (1+2+3+4) iteration which gives the result 10 iterations.
- The sum initial value is 0 and the "sum++", increase the value of the sum by 1.
- So the value of the sum becomes 10 after completing 10 iterations of the inner for loop.
- Hence the 10 will be the output. So the Option d is the correct answer while the other is not.
Answer:
Prolog program are used in the artificial intelligence and the web development in a systematic manner process. As, it is also sometimes known as declarative language which basically consist of some facts and list. Prolog program are divided into the sections that are:
- Domain sections
- Clauses sections
- Predicates sections
- Goal sections
We need each section of the prolog program because all the sections introduced the systematic program and performed there particular functions so by using all these processing steps an efficient function are formed.
