A trusted Computing base is the security model feature that in theory has one name or label of the security kernel.

What is meant by Security Kernal?

Software, firmware, and hardware components make form the security kernel. And we commonly refer to this as the trusted computing base or TCB. All interactions between our subjects and objects are mediated by the security kernel, which is provided to us by the trusted computer infrastructure.

What is the security model?

A computer model that may be used to specify and enforce security regulations is known as a security model. It can be founded on the access right model, the analysing computing model, or the computation model; it does not require any prior knowledge. A security policy is built using a structure called a security model.

Everything in a computing system that offers a secure environment for operations is known as a trustworthy computing base (TCB). It is one of the features of the Security model.

Therefore, a Trusted Computing base is the security model feature.

The theoretical basis for the minimum number of disks would be 40 that should be configured to meet the requirements of the application.

The hard disk is a secondary storage device that is used to store data permanently.

Given the requirement of 3600 GB to host a database.

The storage environment should support 4800 IOPS during its peak processing cycle.

The disks available for configuration provide 120 GB of usable capacity,

The support of a maximum of 160 IOPS.

Number of disks required = max (size requirement, IOPS requirements)  

To meet the size requirement = 3600 GB / 120 GB = 30 disks  

To meet the IOPS requirement = 4800 IOPS/(160 × 0.75 IOPS) = 40 disks  

Number of disks required = max (30, 40) = 40 disks

Thus, the theoretical basis for the minimum number of disks would be 40 which should be configured to meet the requirements of the application.

If dye exists added at 1.0 g/s, and the concentration of dye exists 0.05 % the unknown flow rate would be 7,200 kg/hr. The unknown flow rate exists 7200 kg / hour.

A high-level, all-purpose programming language is Python. Code readability is prioritized in its design philosophy, which makes heavy use of indentation. Python uses garbage collection and has dynamic typing.

If dye is added at 1.0 g/s, and the concentration of dye is 0.05 % the unknown flow rate would be 7,200 kg/hr.

We have to find the concentration of the tracer here

Convert 1 hour to seconds = 60 × 60 = 3600 seconds

1 kg = 1000 g

[tex]$C W=1 g / s\left[\frac{3600 \text { seconds }}{\text { hour }} * \frac{1 \text { kilogram }}{1000 \text { grams }}\right]$[/tex]

We have C = 0.05 %

0.05 % = 0.0005

When we put in these values into the equation:

0.0005 W = 3600 / 1000

simplifying the above equation, we get

0.0005 W=3.6

Divide through by 0.0005

W = 3.6/0.0005

W = 7200 kg/hour

Therefore, the unknown flow rate is 7200 kg / hour.

Array form of lookup is used when you have a small list of values and the values remain constant over time.

A data structure called an array consists of a set of elements (values or variables), each of which is identifiable by an array index or key. Depending on the language, additional data types that describe aggregates of values, like lists and strings, may overlap (or be identified with) array types.

An array is a collection of memory locations, or "boxes," each of which has the same name and can store a single piece of data. An array's data must all be of the same data type. Consider a score table in a game where ten scores must be recorded.

An array is a grouping of identically typed elements that are stored in adjacent memory locations and may each be separately referred to using an index to a special identifier.
