Answer: Please see below as the answer is self-explanatory

Explanation:

For the TCP/IP protocol suite, the IP protocol is the Network (or Internet) layer (Layer 3 in the OSI model), and TCP is one of the possible options for the Transport Layer, (Layer 4 in the OSI model).

Now, how the transport layer is aware that the transport protocol to be used is TCP?

When the network layer receives a packet, reads the IP Header, processes it, and then, after stripping it from the packet, sends it to the immediate upper layer.

In the IP header, there is a field, that tells the network layer, which is the protocol that will take care of the packet payload once processed by the network layer.

This field, has different names in IPv4 and IPv6; It is called PROTOCOL in IPv4, and NEXT HEADER in IPv6.

It has a length of 8 bits, and the binary value included in it, identifies uniquely the type of upper-layer protocol to be used, being the same for the same protocol in both versions of IP protocol.

For TCP, it is 6 in binary: 00000110.

Answer:c)You want to automate a repetitive task to save time

Explanation: Macro is the program that is utilized when there is a requirement of a task or operation to be repeated in a automatic way.This helps in saving the time without commanding the same operation to take place manually.

This program works by taking the into and generating the preset output sequence. Other options are incorrect because it does not help in email functions, correction of the citation in documents or generation of the table.Thus, the correct option is option(c).

The correct option is C. toward the floor.

The magnetic force on the moving negative charge acts towards the floor.

Explanation:

The direction of the force applied on the moving charged particle placed in the magnetic field can be determined with the help of Fleming’s Left hand rule.

The current flows in the direction opposite to the direction of electron. If the electron moves from negative terminal to positive terminal, then the current will flow from positive terminal to negative terminal.

As given, the direction of electron- South to North

So the direction of current will be- North to South

Using Fleming's Left hand rule we get the direction of force in downward direction, i.e. towards the floor.

Assume the availability of class named IMath that provides a static method, toThePowerOf which accepts two int arguments and ret

geniusboy [140]

Answer:

cubeVolume = IMath.toThePowerOf(cubeSide, 3);

Explanation:

Following is the explanation for above statement:

Left side:

cubeVolume is a variable with data-type int, it will store the integer value that is the output from right side.

Right side:

IMath is the class name.
toThePowerOf is the built-in function that takes two arguments of data type int. First is the base and second is the power(exponent) separated by comma. In place of first argument that is the base variable we will pass the variable cubeSide that has been declared and initialize.
Now the output will be stored in the variable cubeVolume.

i hope it will help you!

Discuss whether design considerations need to change for each kind of computer users. support your answer with an example.

vaieri [72.5K]

Each kind of computer users have different knowledge, needs and requirements. For example there is a difference between the computer knowledge of developers and users without technical experience. Because of this, but also why they need and use computers, and what tools they need, design consideration need to change for each kind of computer users.
