Introduction to information technology in technical systems.
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.
The term is commonly used as a synonym for computers and computer
networks, but it also encompasses other information distribution technologies such
as television and telephones. Several industries are associated with information
technology, including computer hardware, software, elektronics, semiconductors,
internet, telecommunications equipment, engineering, healthcare, e-commerce and
computer services.
Humans have been storing, retrieving, manipulating and communicating
information since the Sumerians developed writing in about 3000 BC, but the
term
information technology
in its modern sense first appeared in a 1958 article
published in the
Harvard Business Review
; authors Harold J. Leavitt and Thomas
L.Whisler commented that "the new technology does not yet have a single
established name. We shall call it information technology (IT)." Their definition
consists of three categories: techniques for processing, the application of statistical
and mathematical methods to decision-making, and the simulation of higher-order
thinking through computer programs.
Robotics i
s
an interdisciplinary branch
of engineering and science that
includes mechanical
engineering, elektronic
engineering, information
engineering, computer science, and others. Robotics deals with the design,
construction, operation, and use of robots, as well as computer systems for their
control, sensory feedback, and information processing.

Data transmission
refers to the process of transferring data between two or
more digital devices. Data is transmitted from one device to another in analog or
digital format. Basically, data transmission enables devices or components within
devices to speak to each other.
Data transmission (also data communication or digital communications) is
the transfer of data (a digital bitstream or a digitized analog signal) over a point-to-
point or point-to-multipoint communication channel. Examples of such channels
are copper
wires, optical
fibers, wireless communication
channels, storage
media and computer buses. The data are represented as an electromagnetic signal,
such as an electrical voltage, radiowave, microwave, or infrared signal.
An elektronic signature, or e-signature
, refers to data in elektronic form, which is
logically associated with other data in elektronic form and which is used by
the signatory to sign. This type of signature provides the same legal standing as a
handwritten signature as long as it adheres to the requirements of the specific
regulation it was created under (e.g., eIDAS in the European Union, NIST-DSS in
the USA or ZertES in Switzerland).
Elektronic signatures are a legal concept distinct from digital signatures, a
cryptographic mechanism often used to implement elektronic signatures. While an
elektronic signature can be as simple as a name entered in an elektronic
document, digital signatures are increasingly used in e-commerce and in regulatory
filings to implement elektronic signatures in a cryptographically protected way.
Standardization
agencies
like NIST or ETSI provide
standards
for
their
implementation (e.g., NIST-DSS, XAdES or PAdES). The concept itself is not
21
new, with common law jurisdictions having recognized telegraph signatures as far
back as the mid-19th century and faxed signatures since the 1980s.
