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

List the three control problems associated with competingprocesses and briefly define each.
hjlf

Answer and explanation :

the three control problems associated with competing process are

  • MUTUAL EXCLUSION : We know that some resources are shareable and some are not shareable. which means only one process can access the resource at a time this type of resources are called critical resources this code can be access at only one process at a time. the other process if required to access should not be allowed
  • DEADLOCK: this hold the process without complete for example suppose there are two resources R1 and R2 and two process P1 and P2 and P1 use R1 and P2 use R2 but after some time when P1 needs R2 but R2 is not available as it is used by P2 so the all process will be on hold
  • STARVATION : when priorities are given to the process as high priorities and low priorities. And high priorities process always competing  then low priorities process have to wait for very long time this is called starvation
