ICT (Information Communications Technology) - includes all technologies for the communication of information and covers: any medium to record information, technology for broadcasting information and technology for communicating through voice and sound or images. The communication of information is currently performed with the help of Personal Computers or any (mobile or not) device networked through the Internet through information technology that can transfer information using satellite systems or intercontinental cables. Information technology has become a kind of a hub for communicating information, most often using computers.

IT (Information Technology) - represents the study, design, development, implementation, support or management of computer-based information systems, particularly software applications and computer hardware. IT deals with the use of electronic computers and computer software to convert, store, protect, process, transmit, and securely retrieve information.

Assemblers – implement a symbolic representation of the numeric machine codes and other constants needed to program a particular CPU architecture. This representation is usually defined by the hardware manufacturer, and is based on abbreviations (called mnemonics) that help the programmer remember individual instructions, registers, etc. They are thus specific to a certain physical or virtual computer architecture.

Broadliner – is a big-size distributor owning a wide variety of accounts and selling a wide variety of products.

Distributor – is a seller of products to retailers, to industrial, commercial, institutional, or other professional business users, or to other wholesalers and related subordinated services. The distributor frequently physically assembles, sorts and grades goods in large lots, break bulks, repacks and redistributes in smaller lots.

Integrators – link together different complex computing systems and software applications physically or functionally. They value-add to the system by bringing together discrete systems using a variety of techniques such as computer networking, enterprise application integration, business process management or manual programming.

ISV (Independent Software Vendors) – are companies specialised in developing or selling software, usually for niche markets, such as real estate brokers, scheduling for healthcare personnel, barcode scanning and stock maintenance.

ISVs make and sell software to be added to platforms.

Master VARs – specialize in taking products from wholesalers, combining them with their own intellectual property, and selling them to fellow solution providers and end-user customers.

OEM (Original Equipment Manufacturers) – refer to containment-based re-branding, where a company uses a component of another company in its product, or sells the product of another company under its own brand. OEM refers to the company that originally manufactured the product. They usually use hardware platform components to build larger products.

VARs (Value Added Resellers) – companies adding some features to existing products, then reselling them (usually to end-users) as integrated products or complete "turn-key" solutions. This practice is common in the electronics industry, where, for example, a software application might be added to an existing hardware. This value can come from professional services such as integrating, customizing, consulting, training and implementation or can be added by developing a specific application for the product designed for the customer's needs which is then resold as a new package. VARs incorporate platform software into their own software product packages.

First Tier – are companies in the business of distribution who perform as selling locations for certain brands. They represent the first level of their indirect distribution chain.

Second Tier – companies who have selected First Tier resellers as one of their suppliers of a certain brand and who generally sell to the end-user. They represent the second level of the distribution chain.

BPO (Business Process Outsourcing) - contains the transmission of processes along with the associated operational activities and responsibilities, to a third party with at least a guaranteed equal service level and where the client contains a firm grip over the vendor for mutual long term success.

Sales Out – represent the manufacturer's effort to sell its products at the second tier level.

SOW (Share of Wallet) – is a survey method used in the performance management that helps managers understand the amount of business a company gets from specific customers. It represents the percentage of a customer's expenses for a product that goes to the company selling the product.

TCO (Total Cost of Ownership) - is a financial estimate designed to help consumers and enterprise managers assess direct and indirect costs commonly related to software or hardware. It is a form of full cost accounting and reflects not only the cost of purchase but all aspects regarding the further use and maintenance of the equipment, device, or system considered.
