1 answer:

6 0

Answer: When we type the value into two different cells and then have another cell with the answer, we can then easily change the values in the cells and Excel will automatically recalculate the solution for us.

Hope this helps. :)

What classes should I take in high-school for majoring in computer science?

Gala2k [10]

Answer:

Computer science are the disciplines that study information, computing and the applications or ecosystems where they are developed. It is a science that comes from applied mathematics and has 3 branches that are quite well known. On the one hand we have software engineering, secondly theory as such (primary study of algorithms and data, etc.) and finally the application of the amalgam of the first two, which end up resulting in disciplines such as big data, cybersecurity or computer security, machine learning, artificial intelligence, etc. However, we are talking about a very broad science with various branches of work. Technological advances that have improved the scope of education, now allow us to develop in specific skills and computer science is one of the macro careers that have benefited the most thanks to the diversity of subjects it encompasses. This is where the on-demand courses available on the edX platform come in. Computer scientists are in one of the best times for their career advancement. We invite you to be part of the technological development and information and computing technologies through online courses.

When in global configuration mode, which steps are necessary to edit an ip address on an Ethernet interface?

katrin2010 [14]

Answer:

I. You should enter interface configuration mode.

II. Configure the IP address and subnet mask.

Explanation:

A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.

Some examples of network nodes are modem, hubs, computer, switches, phone and printers.

In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.

In Cisco devices, there are five (5) main types of command modes;

1. Sub-interface configuration mode.

2. Interface configuration mode.

3. Line configuration mode.

4. Router configuration method.

5. Global configuration mode.

Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.

In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;

I. You should enter interface configuration mode using the "configure terminal" command.

II. Configure the IP address and subnet mask.

See an example below;

"Router(config-if)# IP address 192.168.1.2 255.255.255.0"

With the provided information the class can be written as above.

Create a class called SportsCar. Since it extends from the Car, you need to type extends Car after the class name. This implies that it is a subclass of the Car class.

Then, declare its protected variables:

a string called myColor that will hold the color,

a float myEngine that will hold the engine size

a string mySuspension that will hold the suspension type

a string myTires that will hold the tire type
