What is IT?

 IT services have been making work easier for years, but do you know when, where, and how they developed? So, let's learn more about the history of the IT industry.

IT Service means Information and Technologies as a service. IT as a service delivers technologies to businesses, organizations, industries, and everyone. That provides the business model for now.

Information technology services are best managed by providing work, standardizing revenue, and managing professionally. Employees in this service contribute to Ingress’s profitability by ensuring cost transparency, productivity, and more. The business gains more consumption and a time-saving way of managing the enterprise.

The Information Technologies System is the first step to understanding what IT services are. The information technology field consists of information systems, communication systems, and IT-related peripherals like hardware and software, etc. That is utilized by IT users to create, process, store, retrieve, and exchange all kinds of data.

History: 

Humans have stored, retrieved, manipulated, and communicated information since 3000 BC when the Sumerians developed writing in Mesopotamia. However, the term information technology was first used in a 1958 article published in the Harvard Business Review, in which Harold J. Leavitt and Thomas L. Whisler commented that ". the new technology does not yet have a single established name.

Information technology encompasses several products or services in economics, including computer hardware, software, electronics, semiconductors, the internet, telecom equipment, and e-commerce.

Their definition has three components:

Techniques for processing

statistical methods used in decision-making, and

simulation of higher-order thinking through computer programs.

Based on storage and processing technologies, IT development can be divided into four phases: pre-mechanical (3000 BC - 1450 AD), mechanical (1450-1840), electromechanical (1840-1940), and electronic (1940-present).

Now we start learning what IT services are, IT Services has many sub-services out of which we will learn about services today, and that was the Search services and Email services, and that was:

THE EMAIL SERVICES:

The technology and services it provides for sending and receiving electronic messages (called "letters" or "electronic letters") over a distributed (including global) computer network.

The characteristics and structure of electronic mail are virtually the same as that of regular (paper) mail, as it borrows both terms (mail, letter, envelope, attachment, box, delivery, and others) and features (ease of use, message transmission delays, sufficient reliability and yet no guarantee of delivery).

 The advantages of e-mail are: easily perceived and remembered by a person addresses of the form user_name@domain_name (for example, [email protected]); the ability to transfer both plain text and formatted, as well as arbitrary files; independence of servers (in the general case, they address each other directly); sufficiently high reliability of message delivery; ease of use by humans and programs.

THE SEARCH SYSTEM SERVICES: 

A software and hardware complex with a web interface that provides the ability to search for information on the Internet. A search engine usually means a site that hosts the interface (front-end) of the system.

The software part of a search engine is a search engine (search engine) — a set of programs that provides the functionality of a search engine and is usually a trade secret of the search engine developer company.

In addition to searching World Wide Web sites, some systems can search FTP servers, online stores, and Usenet newsgroups for information. Improving search is one of the priorities of the modern Internet (see the Deep Web article about the main problems in the work of search engines).

Statista reports, that search engine usage was distributed as follows:

Google — 86,64%;

Bing — 7%;

Yahoo! — 2.75%.
