Question Discussion & Solution

The correct answer is option 4.

Concept:

CPU Scheduling is a process of determining which process will own CPU for execution while another process is on hold. All Cpu scheduling algorithms use various parameters which are,

Arrival Time: Time at which the process arrives in the ready queue.

Schedule time: Time at which the process arrives ready to running state.

Completion Time: Time at which the process arrives running to terminate state.

Burst Time:  Time spends the process running state.

Turn Around Time:

Turn Around Time= Completion Time – Arrival Time.

Waiting Time:

Waiting time is the total time spent by the process in the ready state waiting for the CPU.

Response time:

Response time is the difference between first execution time and Arrival time.

CPU utilization:

CPU utilization refers to a computer's usage of processing resources or the amount of work handled by a CPU.

Throughput:

Throughput is the amount of work completed in a unit of time.

Throughput = no .of process completed / time taken.

Hence the correct answer is A, B, C, and D.

The correct answer is a Business database.

Key Points

Business Database:

• A business database contains business customers’ past purchases; past volumes, prices, and profits.
•  It also contains buyer team remembers names (and ages, birthdays, hobbies, and favorite foods); status of current contacts; an estimate of supplier’s share of the customer’s business; competitive suppliers; assessment of competitive strengths and weakness in selling and servicing the account; and relevant customer buying practices, patterns, and policies.
• It is considered as a cloud where all the information is stored and kept for use.

The correct answer is Fructose.

Key Points

•  Fructose
  • It is naturally occurring sugar.
  • It is the sweetest sugar.
  • It is a 'monosaccharide', meaning the simplest form of sugar, which means it cannot be broken down into more basic sugar units.
  • Other common examples of monosaccharides are glucose and galactose.
  • The chemical formula of fructose is C₆H₁₂O₆.

Additional Information

• Maltose
  • It is also a sweet sugar which is also known as maltitol sugar.
  • It is mostly found in honey.
  • Its molecular formula is C₁₂H₂₂O₁₁.
• Glucose
  • It is the most abundant monosaccharide, a carbohydrate sub-category.
  • During photosynthesis, glucose is primarily produced by plants and most algae from water and carbon dioxide, using energy from sunlight, where it is used to create the most abundant carbohydrate cellulose in cell walls.
  • The chemical formula of glucose is C₆H₁₂O₆.
• Sucrose
  • It is crystallized white sugar produced by the sugar cane plant and can be found in households and foods worldwide.
  • The formulae for sucrose is C₁₂H₂₂O₁₁.
  • It is a disaccharide so when we hydrolyse it we will get one molecule of glucose and another molecule of fructose.
  • It is also known as table sugar.
  • The formulae for sucrose is C₁₂H₂₂O₁₁.

First is managed by the second.
