Information technology
Information technology (it) — referred to frequently as “tech” or “information technology,” — is basically using computers, Software, networks, databases, and other forms of digital systems to manage, compile, distribute, and retrieve information.
It encompasses the integration of computer Hardware, Software, communication systems and methods of information management to make decisions and streamline operations.
In essence, it is the way that individuals employ digital tools to accomplish tasks more quickly, at a higher level of quality and safety than would be possible if traditional manual methods had been employed.
Historical background of information technology
Throughout history, there have been five generations of information technology. The first four generations refer to improvements in the size and sophistication of computers. The fifth generation refers to the significant societal changes caused by the widespread availability of high-power computing.
Generation one
Generation one was defined by massive machines which were primarily designed for scientific and military applications. Due to the enormous expense of these machines and their size (which required entire rooms), the number of people who were able to use these machines was limited. Modern computers are significantly smaller and less expensive than those large machines and perform a similar role.
Generation two
In the early years of the 20th century, personal computers began to appear which enabled tens of millions of american consumers to have access to the power of computing. Although many americans continued to use mainframes during this time frame, many other americans purchased personal computers for home use.
Generation three
The emergence of the Internet in the latter part of the 1990’s changed information technology forever. When the Internet emerged, for the first time ever, it became possible for people from all over the world to communicate instantaneously. Individuals were now able to send e-mails immediately. Individuals were able to visit websites on the Internet and enjoy an assortment of other Internet services.
Generation four
Present-day mobile technology enables users to carry computing capability into their pockets with the aid of smart phones. Smartphones enable users to access the Internet regardless of where they are and access their email.
Generation five
At present, we are seeing a movement towards cloud computing, artificial intelligence (AI), machine learning, blockchain and the Internet of Things (IoT). Many believe that these technologies will define the future of information technology.
Components of information technology
Information technology is comprised of five key components. Each is described in greater detail below.
Hardware
Hardware represents the physical components that comprise a computer system. Examples include desktop/laptops/desktop server/smart phone/printer/storage device/network switch/router etc. All it systems operate on the basis of Hardware.
Software
Software represents the directions given to computers regarding what actions they should undertake. Software is divided into three categories: application Software (e.g., MS Word); system Software (e.g., Windows or Mac OS x); utility Software (e.g., Disk Cleanup).
Networking
Networking represents the connections formed amongst multiple computers allowing each individual computer to both exchange information and/or share data. Examples include wireless networks (wi-fi); cable networks (ethernet cable); wireless connectivity (bluetooth); fiber optic cables; cellular networks. Because almost all businesses require that their employees’ pc’s be connected to a single printer that is accessible by all employees or allow employees to access resources common to the enterprise (file shares/intranet sites etc.), Networking is essential to just about all commercial companies.
Databases
Databases represent nothing more than an orderly collection of data. Companies utilize databases to organize data in an orderly fashion that may be accessed readily. An example of a type of database includes: microsoft access; ibm db2; oracle database; mysql; postgresql etc.
Security
Cybersecurity represents the steps taken to safeguard computers/networks/data against unauthorized access. Solutions exist to address cyber threats/security concerns that include: firewalls (control incoming/outgoing traffic); anti-viral/anti-malware (identify/detect viruses/malware); encryption (hide data); multi-factor authentication (verify identity before accessing account); intrusion detection/prevention systems (detect/block unauthorized activities); security cameras (visual monitoring); security monitoring teams (monitory for suspicious activity).
