Information technology, or IT, describes any technology that powers or enables the storage, processing and information flow within an organization. Anything involved with computers, software, networks, intranets, Web sites, servers, databases and telecommunications falls under the IT umbrella.
Job sectors are areas of the economy which include various occupations, and the occupations within each sector are typically related to each other in some way. While these jobs are linked within a larger field, each sector requires a workforce with diverse skills and various specialities.

IT sector is considered a sub sector of Information and communication sector. It involves computer systems with Hardware, Software, Network, Infrastructure and associated other equipment. Today this also includes, electronics, telecom, internet, semi-conductors and e-commerce and more!
An IT company is the wider category than a software company. IT companies can be: hardware company, software company, data base company, mobile apps development company, web development company etc.
The three main sectors of the economy are: Primary sector – extraction of raw materials – mining, fishing and agriculture. Secondary / manufacturing sector – concerned with producing finished goods, e.g. factories making toys, cars, food, and clothes.
The primary sector of the economy includes any industry involved in the extraction and production of raw materials, such as farming, forestry, fishing and mining.
Sector. Definition: The part of a circle enclosed by two radii of a circle and their intercepted arc. A pie-shaped part of a circle. It has two straight sides (the two radius lines), the curved edge defined by the arc, and touches the center of the circle.
A sector is a region bounded by two radii of a circle and the intercepted arc of the circle. A sector with a central angle less than 180° is called a minor sector. A sector with a central angle greater than 180° is called a major sector.
Area of Sector
The area of a sector of a circle is ½ r² ∅, where r is the radius and ∅ the angle in radians subtended by the arc at the centre of the circle. So in the below diagram, the shaded area is equal to ½ r² ∅ .To calculate the area of a sector, start by finding the central angle of the sector and dividing it by 360. Next, take the radius, or length of one of the lines, square it, and multiply it by 3.14. Then, multiply the two numbers to get the area of the sector.
To name a sector, use one arc endpoint, the center of the circle and then the other arc endpoint. A circle has radius of 4 in.
The perimeter of the sector includes the length of the radius ×2, as well as the arc length. So the perimeter is the length "around" the entire sector, the length "around" a slice of pizza, which includes it's edges and its curved arc.
The private sector is the part of a country's economic system that is run by individuals and companies, rather than the government. Most private sector organizations are run with the intention of making profit. An industry or business may start out in one sector and move to the other.
A sector with the central angle of 180° is called a half-disk and is bounded by a diameter and a semicircle. Confusingly, the arc of a quadrant can also be termed a quadrant.
In computer disk storage, a sector is a subdivision of a track on a magnetic disk or optical disc. Each sector stores a fixed amount of user-accessible data, traditionally 512 bytes for hard disk drives (HDDs) and 2048 bytes for CD-ROMs and DVD-ROMs. The sector is the minimum storage unit of a hard drive.
The three main sectors of the economy are: Primary sector – extraction of raw materials – mining, fishing and agriculture. Secondary / manufacturing sector – concerned with producing finished goods, e.g. factories making toys, cars, food, and clothes.
The 11 stock market sectors:

- Financials.
- Energy.
- Consumer discretionary.
- Information technology.
- Communication services.
- Real estate.
Many economists recognize the following five economic sectors; the primary sector which includes agriculture, mining and other natural resource industries; the secondary sector covering manufacturing, engineering and construction; a tertiary sector for the service industries, the quaternary sector for intellectual
Industry refers to a much more specific group of companies or businesses, while the term sector describes a large segment of the economy. The terms industry and sector are often used interchangeably to describe a group of companies that operate in the same segment of the economy or share a similar business type.
The three-sector model in economics divides economies into three sectors of activity: extraction of raw materials (primary), manufacturing (secondary), and services (tertiary).
The quinary sector is the branch of a country's economy where high-level decisions are made by top-level executives in the government, industry, business, education, media and nonprofit organizations. The quinary sector is the top economic sector.
There are four types of job. These are primary, secondary, tertiary and quaternary jobs. Primary jobs involve getting raw materials from the natural environment e.g. Mining, farming and fishing. Secondary jobs involve making things (manufacturing) e.g. making cars and steel.

3 Formulas for Calculating The Area of a Sector:
| Using Degrees | Using Radians | When a Portion is Unknown |
|---|
| A = (sector angle / 360) * (pi *r2) | A = (sector angle / (2*pi)) * (pi * r2) | A = (fraction of the circle) * (pi * r2) |
The Service Sector, also called tertiary sector, is the third of the three traditional economic sectors. Activities in the service sector include retail, banks, hotels, real estate, education, health, social work, computer services, recreation, media, communications, electricity, gas and water supply.
The four sectors in the American economy are Government, For-Profit or Business, the Nonprofit or Independent, and Households or Family. While we often think of these as separate entities, they are often inter-dependent.
Examples include mining, quarrying, farming, fishing and forestry, all of which produce raw materials that can be processed in to a finished product. People working in these industries are described as being in the primary sector. Secondary industries are the manufacturing and assembly industries.
