Answer:
The data type defines wich operations can safely be performed to create, transform and use the variable in another computation.
Computer programs use different data types for efficiency, precision, etc.
Treating all data the same would lead to confusion, inefficiency, and errors.
Treating a date like an integer would result in a loss of semantics, limited operations, etc.
We have,
Computer programs use different data types for a variety of reasons:
- Efficiency:
Different data types allow programs to allocate memory and perform operations more efficiently.
- Precision:
Different data types have different levels of precision. For example, using floating-point numbers allows for decimal values but might introduce rounding errors, while integers are exact but can't represent fractions.
- Semantics:
Different data types convey meaning and help programmers and the compiler understand how the data should be used.
- Operations:
Different data types support different operations. For instance, you can't perform arithmetic operations on text strings as easily as you can on numbers.
- Type Safety:
Using distinct data types helps catch errors early in the development process. If you accidentally treat a string as an integer or vice versa, type systems can catch such errors during compilation.
If a date were treated like an integer:
- Loss of Semantics:
Treating a date as an integer would strip away its meaning. Dates have attributes like day, month, and year, which would be lost if they were treated as integers.
- Limited Operations:
Integers can't directly perform operations related to date manipulation, such as finding the difference between two dates or determining the day of the week for a given date.
- Error-Prone:
Treating dates as integers would likely lead to confusion and errors. It would be easy to make mistakes when handling date-related calculations and comparisons.
- Lack of Flexibility:
Dates have a complex structure, including leap years, varying month lengths, and time zones. Treating them as integers wouldn't allow for representing these complexities.
Thus,

Treating all data the same would lead to confusion, inefficiency, and errors.
Treating a date like an integer would result in a loss of semantics, limited operations, etc.

The feature of spreadsheets that will help Rohan decide where to invest his money is;
Option A; Solver
Since he wants to find where to invest his funds for one year between the two fund types. This means in excel, he will make of what we call "IF function".
The "IF" function helps in making logical comparisons between a particular value and what you will expect and as a result, it implies that the "IF" statement can have two results. The first result of the IF function will be the one to show that the comparison is True while the second is to show the comparison is False.Now, in Microsoft Excel, we make use of an add-in program called "SOLVER" that is used for what-if analysis.
Solver is used to find the maximum or minimum value for a formula in the objective cell which is subject to constraints, on the values of other formula cells in that particular worksheet.

Describe the type of gameplay seen during early video games (ex. Spacewar!, Pong).
Answer:
Computer scientists began building rudimentary games and simulations on mainframe computers in the 1950s and 1960s, with MIT's Spacewar! in 1962 being one of the first such games to be played with a video display. The first consumer-ready video game hardware arrived in the early 1970s, with the Magnavox Odyssey, the first home video game system, and the first arcade video games from Atari, Computer Space and Pong, the latter of which was later transformed into a home console version. Pong's success in arcades and at home prompted numerous firms to create clones of the game, resulting in a market contraction in 1978 owing to oversaturation and a lack of innovation.
