after you get a second-level domain name, what more must you do to have a working website for your company? (this is a repeat question. it is important.
A second level domain is the name that comes immediately after the domain extension, such as.com or.net. The website brainly.com was created to explain the difference between top-level domains (TLDs) and second-level domains (SLDs).
After you get a second-level domain name, You must do these follwing steps to have a working website for your company:
1.Secure your business name at companies house -
If your newly registered domain name isn’t being used for business purposes, or you’ve already registered your company name, you can skip this step.
You’d think this would be the very first thing any SME does before getting started with a new company, however, during the excitement of coming up with a genius idea that could make you an overnight millionaire, it’s easy to forget these things.
2.Set up an email address -
Does any business run day-to-day without email anymore? There might be a few people holding out, but for the most part, using email is an integral aspect of running a website / company.
3.Secure your social media accounts -
Before you get too involved with one particular social media network it makes sense to secure all the relevant social media accounts for your website/business.
4.Get started with email marketing (Mailchimp) -
With the rise of social networks, the term “Email is dead” has become an age old adage, but it couldn’t be further from the truth.
A well-maintained customer mailing list is an absolutely vital asset for any business/website owner. And why wouldn’t it be? The people on your mailing list are familiar with your brand, products and services, and in many cases are ready to buy!
5.Create a holding / under construction page -
With the excitement of a new business or website launch comes the urge (and the need) to tell the world of your future plans.
If you do this before you have any kind of web page present it’s an opportunity missed. This is why it’s a good idea to get a holding page for your website online.
6.Add SSL to your domain name -
Look up at your web browser address bar right now. You see that little green padlock to the left of our web address? That’s SSL in action. You’ll also notice that our address starts with “https” instead of “http”.
SSL stands for Secure Socket Layer and is the industry standard method of encrypting data sent between web browsers (your computer) and servers (web hosts).
7.Set up the blank version of your domain -
When we think of the web, we tend to assume all websites start with the “www” prefix. However, the chances are you probably visit websites on a regular basis without using “www” at all.
8.Verify your site with G*ogle Search Console / Webmaster Tools -
What G*ogle actually does is search their index of the internet. This index is created by relentlessly scanning the web for new sites, pages and content. This is how G*ogle can provide search results so quickly.
This makes Search Console (formerly Webmaster Tools) an absolute necessity for any website looking to get found online via search.
9.Add G*ogle Analytics -
What would be the point of getting a website online if you never knew how many people are using it? Not only that, wouldn’t you like to know how these users find your site? What pages they like? What pages they don’t like?
I could go on but you get the idea…
Go*gle Analytics is a professional-level analytics tool for your website and can give you the answers to all these questions and much, much more.
Using this information allows you to make an informed decision as to what changes you can make to your site that will help make a real difference.
10.Don’t let your domain expire -
While this might seem like an obvious one, you’d be surprised by the amount of people who let their domains expire without even realising it has happened – and we don’t just mean hobbyists and small business owners either.

you have just built a house out in the country and it comes to your attention that you need to install a lightning rod. being naturally curious you ask a hardware salesperson how lightning rods work and they correctly tell you that
When you ask a hardware salesperson how lightning rods operate because you're naturally curious, they respond correctly by explaining that corona discharge is used to remove localized charge accumulations.
Explain about the charge accumulations?
Accumulation of Charge Electrons transfer from one surface to the other whenever two materials that are not comparable come into contact. One of these materials acquires a positive charge, and the other acquires a negative charge as these materials are separated and more electrons stay on one surface than the other.
An accumulation of electric charges on things is known as static electricity. When electrons go from one thing to another, it happens. Static discharge is the abrupt movement of electrons from one charged object to another.
A charge builds up around a contact between two metals with varying conductivities when current flows across the contact. The current and charge accumulation are linearly related.

What is Multi-Factor Authentication (MFA)?With multi-factor authentication (MFA), a user must give two or more verification factors in order to access a resource, such as an application, an online account, or a VPN. A solid identity and access management (IAM) policy must include MFA. MFA requests one or more extra verification criteria in addition to a username and password, which lessens the chance that a cyberattack will be successful.By requiring users to provide additional forms of identification in addition to usernames and passwords, MFA will improve security within your organization. Usernames and passwords are crucial, but they are also susceptible to brute force attacks and can be taken by unauthorized parties.

consider the number dddddddd in hex. what is the base-4 representation (dddddddd)16? (this should require no additional calculations.)
So, this conversion is easy because there is no additional calculation required. Only grouping is required and each of the hexadecimal digits is broken into two bases-4 digits.
The answer provided below has been developed in a clear step by step manner.
Step: 1
The given number in base 16 is = 0xdddddddd
In the above representation, one hexadecimal digit is representing a group of four binary digits. This is because the base 16 is a power of 2.
[tex]2^{4}[/tex] = 16
The power of 2 decides, how many binary digits will be grouped.
We need into base-4 representation, and base 4 is also a power of 2.
[tex]2^{2}[/tex] = 4
In base-4, one digit is representing a group of two binary digits.
Step: 2
The given number in base-16 is = 0xdddddddd
The above number in base-2 will be = 11011101110111011101110111011101
For base-4 conversion, we will make a group of two digits and then write the equivalent digit.

In a real-time strategy game, each player positions buildings and directs a variety of forces under their indirect control to secure specific sections of the map and/or take out the resources of their rivals.
The ability to build extra units and structures is typically restricted in an RTS game by the need to use up collected resources. These resources are then obtained by holding certain types of units and structures that are specifically designed for this purpose, as well as specific types of special spots on the map.
More specifically, the standard RTS game includes resource collecting, base construction, technological advancement within the game, and indirect control of forces.
