First, briefly about hosting. Hosting — dedicated server resources on the network that allow you to host something.
"Hosting vs server" (pros):

- there is no need for an administrator;
- ease of use.

- cheaper web hosting;
- configured as you like (within the framework of the administrator's qualifications);
- more available disk space.

Now about domains. So, what is a domain (domain name), how much it costs and why it is needed.
First there will be a brief technical information about what it is, then how much it costs and why it is needed. If technical information is not needed, the next section is marked in bold.

Domain (domain name) is a symbolic name that serves to identify regions — units of administrative autonomy on the Internet — as part of a higher hierarchy of such an area. Some domain names are reserved for testing and cannot be registered, for example, let's take the standard domain from this selection:

To consider the concept, you also need to know what a URI and URL are:
URI is a unified (uniform) resource identifier. This is a sequence of characters identifying an abstract or physical resource:
Small Enterprise IT Organization: Domain, web hosting and virtual/real server Small business, Rationalism, Domain, Hosting, Server, VPS, Longpost

The URL is a subset of the URI (see above). An anchor is not a link to a document, but to a place in the document itself.
So let's consider the full URI addresses. Unfortunately, it will not work in one:

Reading the address correctly:

. - the dot between com and :8080 is the designation of the root of the domain name system. Since it is present in all addresses, it is usually not used, however, for example, when setting up domain zones, the absence of this point leads to errors. An entire international organization is responsible for this point (ICANN - Internet Corporation for Assigned Names and Numbers or the Corporation for Managing Domain Names and IP Addresses). This is due to a simple rule — whoever owns the domain zone can do anything in it...

.com is the domain of the first (or as some say the top) level. Allocated accordingly by ICANN.

example — second-level domain. It is allocated by the registrar who has agreed with ICANN to allocate names in the corresponding zone.

aaa is a level 3 domain. Allocated by the owner of the second-level domain.

bbb is a level 4 domain. Allocated by the owner of the third-level domain.

ccc is a level 5 domain. Allocated by the owner of the fourth-level domain.

:8080 — the port to which the connection takes place. Let's focus on the concept of "port" in more detail. The fact is that several clients can be connected to the same server at the same time to different programs running on the server. So that the data of clients and programs do not overlap with the data of other clients and programs, the data is marked with a special label called "port". Ports with numbers up to 1024 are reserved for "standard" programs.

http is a data transfer protocol.

/file — the directory/folder on the server where it is located

/example.php — a file on the server that receives:

?login=admin&pass=admin — login and pass parameters with the value admin.

The second example:

I will not describe the intersections with the first one, I will only note the differences: the login and password are displayed in the URI and the protocol has been changed.
So, a domain is usually understood as a second-level domain zone, i.e. a symbolic name that uniquely identifies a service on the network.

How much does it cost
Domain prices are set by domain name registrars. The cost of a level 2 domain starts from $5. Different registrars offer different prices, but only one thing is important for the client — domain verification (linking the name to a specific individual or legal entity).
 Attention! Some registrars distribute domains for free, but at the same time either register them for themselves or leave the domain management to themselves. If the site is promoted, then the registrar can simply sell the promoted domain to competitors.

Why is it needed
The domain zone of the second level is prestige, benefit and convenience. Agree that the mail it looks much more solid than . The benefit lies in the fact that the owner of the second-level zone can "open to the world" his website, mail service, messaging, file storage, etc. At the same time, these services can be monetized and make a profit .

But on the topic of convenience, it is worth dwelling in more detail.

Firstly, this is a website. The site is an automation system, passive advertising and a passive source of customers. For the first 3-4 months, he works idly, but then he will throw someone up. The number of clients from the site strongly depends, firstly, on the promotion, and secondly, on the completeness and quality of information. "We will call you back" - this is about 80% of refusals because do not flatter yourself, you are far from a monopolist (Gazprom and Rostelecom are sorry) and once a person is looking for something, it is easier for him to open the site following you than to leave a request and wait for managers.
The practice of observation shows that a person first goes through the full options, and if he does not find the right one, he leaves a request for communication. A well—designed website reduces the labor costs of salespeople, a good flow of customers, while customers who have already received most of the necessary information and are already ready to buy something.
Errors in the site and salespeople begin to flood with clarifying calls, questions... People are very busy, but the sales are worth it. An effective website can save 75% of the time of sales staff, i.e. if a salesman without a website leads 10 clients a month, then with a good website he will lead up to 40.

Remark: there is an invasion of consumer goods in site construction. The vast majority of sites are outright slag, and, most importantly, most of the slag comes from "elite" web studios. "Sucker is not a mammoth" - it is extremely rare for customers to meet specialists who are able to adequately assess the quality of work. This leads to the fact that every year there are fewer and fewer professionals in the field of site construction. In the dry result, on the part of the customer, firstly, financial losses, and secondly, it will be simply impossible to get a high-quality website soon due to the lack of specialists...

Secondly, this is corporate email and I think everyone knows and understands what advantages it has. For your domain, corporate mail is primarily freedom. "At the start", all names in the domain are free, that is, you can choose any beautiful and sonorous name, and not register after sorting through all the beautiful options .

Thirdly, the URI allows you to firmly fix a document or resource. This means that all standard commercial offers, presentations, booklets, etc. can be posted on the server / hosting and send out not letters, but links to them. In particularly advanced organizations, there is a competently configured (if there is no person who will do everything correctly, then do not — otherwise hаcking your network will become commonplace) addressing by type: employee.department.domain, with the correct connection setup, this allows you to first access computers directly (including from a local network), and secondly, an employee can work at a computer from any place where there is Internet.

Fourth, the discussion of corporate issues through public messengers can be compromised. A corporate messaging server makes correspondence much more private and controlled.
Fifth, the domain allows you to create a network between remote points (VPN). Different offices and remote workplaces can be included in a single domain.
Sixth, you can organize your audio-visual communication (your Skype). Again, everything is much more private than public services.

There are many more points, but the general idea is the same — the domain zone is a part of the global network controlled by you, where you can do everything that is in the "big" network.


I read and cry. Do you need a domain to organize a VPN, a messenger, seriously? The domain is only needed for the website and external mail, no more. Corporate issues are usually discussed via internal mail.
Advantages of web hosting compared to the server? With a full-fledged server?
Small organizations need not only a website, but also, as a rule, a terminal server with all sorts of specific (or not so) software, virtual machines with additional services - how will hosting cope with this and how much can it cost?


And why do you think, within the framework of one provider, typical shared hosting services cost 2-4 times more expensive than typical VPS web services?
Also, you didn't mention a word about SEO. For a new site to be on the same IP with upgraded sites is a very fat plus to the trust of search engines.
Most often, sites are made for these purposes, that is, precisely so that search engines bring new customers to this site, and not so that the site domain is typed in letters by reading it from a paper business card. Most likely, once a person has a paper business card, it's already a client without a website, right?

Programmers will laugh. When people ask me where it is best to be placed so that information can be found.
After all, are there any hosting services more reliable than these?
