Answer
Abstraction in GPS technology allows the system to use clearly defined interfaces while enabling the integration of additional, more complex functionalities.
Explanation
The GPS system employs abstraction to organize layers of complexity for user interaction. It connects satellite-based positioning and timing systems to enable a radio receiver to acquire signals across four dimensions—latitude, longitude, altitude, and time—after synchronizing this data.
Response:
d. RAID 6
Clarification:
RAID is a technological method for data storage that integrates several physical hard drive components into a unified logical structure. Its primary purpose is to ensure both performance and data redundancy.
RAID 0 is focused on data striping, but it lacks redundancy.
RAID 1 enhances performance to nearly double but restricts disk space usage to around 50%.
RAID 5 offers both redundancy and improved performance, though it is constrained by smaller drive sizes.
RAID 6 provides redundancy as well but with a decrease in performance.
RAID 10 boosts both performance and data security.
Hence, RAID 6 is the optimal choice that emphasizes redundancy at the cost of speed.
Answer:
Refer to the explanation
Explanation:
Number of Mobiles=x1
Number of Workstations=x2
Constraints:
50x1 + 70x2 <= 1,60,000
250x1 + 700x2 <= 12,000,000
x1 >= 0 x2 >= 0
Objective function N(x1, x2) = 7800000000 x1 + 7200000000 x2
Excel formulae:
G17 = D9 * E7 + F9 * G7
G18= D10 * E7 * F10 * G7
G19= E7
G20= G7
G21= I17 * E7 + I18 * G7 (This will yield the Maximum)
And E7 and G7 will be the solution.
Set up your sheet as shown in the diagram and apply the formulas.
Access the tool and select solver. Upon opening the Solver dialog, confirm ‘Assume Linear model’ and ‘assume non-negative’. Click to solve the model and keep the solution.
