Which layer of the OSI model provides a user interface in the form of an entry point for programs to access the network infrastr

Alexandra [31]

The OSI model layer that provides a user interface in the form of an entry point for software programs to access the network infrastructure is: application layer.

<h3>What is the OSI model?</h3>

OSI model is an acronym for open systems interconnection and it comprises seven (7) main layers, which typically starts from the hardware layers (layers in hardware systems) to the software layers (layers in software systems)

<h3>The layers of the OSI model</h3>

In Computer networking, the seven (7) layers of the OSI model include the following in sequential order;

Physical Layer

Data link Layer

Network Layer

Transport Layer

Session Layer

Presentation Layer

Application Layer

The uppermost layer of the OSI model which is the "application layer" gives software programs an access to the services that allow internet connection or network infrastructure.

Which of the following statements represents the number of columns in a regular two-dimensional array named values?

puteri [66]

Answer:

(a) values[0].length

Explanation:

In programming languages such as Java, an array is a collection of data of the same type. For example, a and b below are an example of an array.

a = {5, 6, 7, 9}

b = {{2,3,4}, {3,5,4}, {6,8,5}, {1,4,6}}

But while a is a one-dimensional array, b is a regular two-dimensional array. A two-dimensional array is typically an array of one-dimensional arrays.

Now, a few thing to note about a two-dimensional array:

(i) The number of rows in a 2-dimensional array is given by;

<em>arrayname.length</em>

For example, to get the number of rows in array b above, we simply write;

<em>b.length </em>which will give 4

(ii) The number of columns in a 2-dimensional array is given by;

<em>arrayname[0].length</em>

This is with an assumption that all rows have same number of columns.

To get the number of columns in array b above, we simply write;

<em>b[0].length </em>which will give 3

Therefore, for a regular two-dimensional array named values, the number of columns is represented by: values[0].length

Aleksandr-060686 [28]

Answer:

b. Code an include preprocessor directives for the members

Explanation:

Namespace in programming can be defined as the declarative region which provides scope for the identifiers such as the functions, name of the types, variables, etc.

The namespaces are $\text{used to organize}$ the code into the logical groups and also used to prevent the name collision.

The ways that can be used outside the namespace $\text{can access the members}$ as :

-- the code used the fully qualifies name

-- by using the declaration to bring one of the identifier into the scope

-- by using the directive to bring all the things in the newspaper into the scope.

Thus the correct option is (b).
