The document provides definitions and explanations of various information technology terminologies, including information technology, software, networking, databases, cloud computing, SQL, SharePoint, ERP, CRM, Java, web applications, smartphones, Android, Apple TV, and mobile communication standards 3G and 4G. Each term is briefly defined, highlighting its significance and function within the IT landscape. The content serves as an overview for understanding these essential concepts in the field of technology.

1. What Is?
Definition of Different IT
Terminologies

2. What is Information
Technology:
 Information technology (IT) is the
application of computers and
telecommunications equipment to store,
retrieve, transmit and manipulate data,
often in the context of a business or other
enterprise.

3. What is Software:
 Computer software, or just software, is any
set of machine-readable instructions
(most often in the form of a computer
program) that directs a computer's
processor to perform specific operations.
The term is used to contrast with
computer hardware, the physical objects
(processor and related devices) that carry
out the instructions. Hardware and
software require each other and neither
has any value without the other.

4. What is Networking:
 A computer network or data network is a
telecommunications network that allows
computers to exchange data. The
connections (network links) between
networked computing devices (network
nodes) are established using either cable
media or wireless media. The best-known
computer network is the Internet.

5. What is Database:
 A database is an organized collection of
data. The data are typically organized to
model relevant aspects of reality in a way
that supports processes requiring this
information. For example, modeling the
availability of rooms in hotels in a way that
supports finding a hotel with vacancies.

6. What is Cloud Computing:
 Cloud computing is a colloquial
expression used to describe a variety of
different types of computing concepts
that involve a large number of computers
connected through a real-time
communication network (typically the
Internet). Cloud computing is a jargon
term[citation needed] without a
commonly accepted unequivocal
scientific or technical definition.

7. What is SQL:
 SQL, Structured Query Language is a special-
purpose programming language designed
for managing data held in a relational
database management system (RDBMS).
Originally based upon relational algebra and
tuple relational calculus, SQL consists of a
data definition language and a data
manipulation language. The scope of SQL
includes data insert, query, update and
delete, schema creation and modification,
and data access control. Although SQL is
often described as, and to a great extent is, a
declarative language (4GL), it also includes
procedural elements.

8. What is Sharepoint:
 Microsoft SharePoint is a Web application
platform developed by Microsoft. First
launched in 2001, SharePoint has
historically been associated with intranet,
content management and document
management, but recent versions have
significantly broader capabilities. It is the
dominant software for creating
organizational intranets with a recent
survey indicating that around 50% of all
intranets are developed using SharePoint.

9. What is ERP:
 Enterprise resource planning (ERP) is a
cross-functional enterprise system driven
by an integrated suite of software
modules that supports the basic internal
business processes of a company. ERP
gives a company an integrated real-time
view of its core business processes such as
production, order processing, and
inventory management, tied together by
ERP applications software and a common
database maintained by a database
management systems.

10. What is CRM:
 Customer relationship management
(CRM) is a model for managing a
company’s interactions with current and
future customers. It involves using
technology to organize, automate, and
synchronize sales, marketing, customer
service, and technical support.

11. What is Java:
 Java is a general-purpose, concurrent,
class-based, object-oriented computer
programming language that is specifically
designed to have as few implementation
dependencies as possible. It is intended
to let application developers "write once,
run anywhere" (WORA), meaning that
code that runs on one platform does not
need to be recompiled to run on another.

12. What is Web Application:
 A web-based application is any
application that uses a web browser as a
client. The term may also mean a
computer software application that is
coded in a browser-supported
programming language (such as
JavaScript, combined with a browser-
rendered markup language like HTML)
and reliant on a common web browser to
render the application executable.

13. What is a Smartphone:
 A smartphone, or smart phone, is a mobile
phone built on a mobile operating system,
with more advanced computing
capability and connectivity than a
feature phone. The first smartphones
combined the functions of a personal
digital assistant (PDA) with a mobile
phone.

14. What is Android:
 Android is a Linux-based operating system
designed primarily for touchscreen mobile
devices such as smartphones and tablet
computers. Initially developed by
Android, Inc., which Google backed
financially and later bought in 2005.

15. What is Apple TV:
 Apple TV is a digital media receiver
developed and sold by Apple Inc. It is a
small form factor network appliance
designed to play digital content from the
iTunes Store, Netflix, Hulu Plus, YouTube,
Flickr, iCloud, MLB.tv, NBA League Pass,
NHL GameCenter…

16. What is 3g:
 3G, short for third Generation, is the third
generation of mobile telecommunications
technology. 3G telecommunication
networks support services that provide an
information transfer rate of at least 200
kbit/s.

17. What is 4g:
 In telecommunications, 4G is the fourth
generation of mobile phone mobile
communication technology standards. It
is a successor to the third generation (3G)
standards. A 4G system provides mobile
ultra-broadband Internet access, for
example to laptops with USB wireless
modems, to smartphones, and to other
mobile devices. Conceivable applications
include amended mobile web access, IP
telephony, gaming services, high-
definition mobile TV, video conferencing,
3D television, and cloud computing.
