Discuss the core technologies and provide examples of where they exist in society. Discuss how the core technologies are part of

Vika [28.1K]

Answer:

Part A

The core technologies are the technologies which make other technologies work or perform their desired tasks

Examples of core technologies and where they exist are;

Thermal technology, which is the technology involving the work production, storage, and transfer using heat energy, exists in our refrigerators, heat engine, and boilers

Electronic technology is the technology that involves the control of the flow of electrons in a circuit through rectification and amplification provided by active devices. Electronic technology can be located in a radio receiver, printed circuit boards (PCB), and mobile phone

Fluid technology is the use of fluid to transmit a force, provide mechanical advantage, and generate power. Fluid technologies can be found in brakes, automatic transmission systems, landing gears, servomechanisms, and pneumatic tools such as syringes

Part B

The core technologies are the subsystems within the larger systems that make the larger systems to work

The thermal technology in a refrigerator makes use of the transfer of heat from a cold region, inside the fridge, to region of higher temperature, by the use of heat exchange and the properties of the coolant when subjected to different amount of compression and expansion

The electronic technologies make it possible to make portable electronic devises such as the mobile phones by the use miniaturized circuit boards that perform several functions and are integrated into a small piece of semiconductor material

Fluid technologies in landing gears provide reliable activation of the undercarriage at all times in almost all conditions such that the landing gears can be activated mechanically without the need for other source of energy

Given that Jamie worked 50 hours (Hours = 50) last week and earns $10.00 an hour (Rate = 10), how much did Jamie earn last week,

quester [9]

Answer:

Jamie earned (Total pay) $500.

Explanation:

We are given the following code:

If (Rate >=10) OR (Hours <=40) Then

TotalPay = Hours * Rate

Else

TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5

End If

Let us understand the code line by line:

The first line contains an if statement with 2 conditions:

i.e. 1st condition:

The rate is greater than or equal to 10

2nd condition:

Number of hours are lesser than or equal to 40.

There is OR between the two condition i.e. the statement next to if() statement will get executed if any one of them becomes true and else part will not be executed.

The next statement is:

TotalPay = Hours * Rate

It calculates the pay if any of the two conditions written earlier becomes true.

Next statement is else statement:

It will get executed given that the above if() statement becomes false.

Now, we are given that Jamie worked 50 hours last week and earns $10.00 an hour:

i.e.

Hours = 50

Rate = 10

Now, let get to the code execution.

The first condition is true i.e. Rate >= 10 (because Rate is 10 here)

So, the following statement will be used to calculate the Total pay:

TotalPay = Hours * Rate

and else part will not be executed.

TotalPay = 50 * 10 = $500

Jamie earned (Total pay) $500.

1. Explain the difference between a web browser and a search engine. (2 points)

Elan Coil [88]

Answer:

1. A browser is used to access websites and web pages whereas a search engine is used to search for particular information.

2. Indexing is the process by which search engines organise information before a search to enable super-fast responses to queries.

3.Search engines are used to find specialized data rapidly whereas web directory is used to find a list of different sites.

4. The working behind the PageRank algorithm is that a page with a large number of in- links(a link from an important page) to it, then its outgoing links to other pages also become important. It gives more importance to back links of a web page and propagates the ranking through links.

5. Look for Sites from Established Institutions 2. Look for Sites with Expertise 3. Steer Clear of Commercial Sites 4. Beware of Bias 5. Check the Date 6. Consider the Site's Look 7. Avoid Anonymous Authors 8. Check the Links
