Answer:
The reliance on ______ as the design methodology for relational databases is seen as a stumbling block to its use in OLAP systems:
c. normalization
Explanation:
- The OLAP systems are those type of software that are used to analyse the data stored in a database. OLAP stands for online analytical processing. This software allows the user to analyse different data like demographic data etc.
- The reliance on normalization as the design methodology for relational databases is seen as stumbling block to its use in OLAP systems because in operations like creating, retrieving, updating or deleting of data, the de-normalization structure is preferred instead of normalization as we can avoid the data duplication as well as to increase the speed of processing.
Complete Question:
1. A wireless technology standard for exchanging data over short distances
2. A particular brand of mobile phone/PDA
3. A network that operates over a limited distance, usually for one or a few users
1. Bluetooth
2. PAN
3. Blackberry
Answer:
1. Bluetooth 2. Blackberry . 3. PAN
Explanation:
1. Bluetooth is a wireless technology standard, used in order to exchange data between mobile devices, like smartphones, tablets, headsets, wearables, over short distances in a one-to-one fashion (which means that it is not possible to build a network based in Bluetooth).
2. Blackberry is a brand of mobile phones/PDAs, very popular a decade ago, because it was the first one to allow mobile users to access e-mails and messages from anywhere, at any time.
3. PAN (Personal Area Network) is an ad-hoc network that it is only available for data exchange at a very short distance, within the reach of a person, i.e. a few meters as a maximum.
It is thought to allow someone to interact with his nearest environment (laptop, tablet, PDA) and it can be wireless (like Bluetooth) or wired (via USB cables).
Answer:
public static double areaSum(Circle c1, Circle c2){
double c1Radius = c1.getRadius();
double c2Radius = c2.getRadius();
return Math.PI * (Math.pow(c1Radius, 2) + Math.pow(c2Radius, 2));
public static void main(String[] args){
Circle c1 = new Circle(6.0);
Circle c2 = new Circle(8.0);
areaSum(c1,c2);
}

The answer to this question is given below in the explanation section.
Explanation:
The CPU is responsible for processing instruction. CPU instruction processing goes through three stages. Fetch, Decode, and Execute.
When the program runs, program code is copied from secondary storage into main memory. CPU's program counter set to the first instruction of the program stored in memory where the program starts executing.
When a program is being executed, it goes through fetch-decode-cycle. which repeats over and over again until reaching the STOP instruction.
The processor check which next instruction to be executed, then the processor fetches that instruction value from the memory location. once the instruction being fetched it gets decoded and executed. This instruction processing cycle repeating until the CPU finds a stop instruction.
