Information and communication technology (ICT) is a field of study that focuses on how humans communicate. It encompasses the design, development, and application of computer hardware, software and networks to support human interaction. An information technology (IT) professional is someone who works within this field.
Computer hardware
A CPU (central processing unit) is the main part of your computer, which runs programs and manipulates data. It's made up of millions upon millions of transistors, which are tiny electrical switches that can be turned on or off to perform calculations. The first CPUs were built back in 1956 by John von Neumann, who also created modern computers like ENIAC and EDVAC (which stands for Electronic Numerical Integrator And Computer). A CPU has two sets of registers: one for input/output operations such as reading from memory or writing to disk; another register for storing intermediate results produced during calculation operations performed by itself or other parts within its architecture
Computer software
Computer software is the set of programs that control a computer system. These programs are written in words and/or numbers, stored on storage media like disks or hard drives, loaded onto memory (or RAM), and run by an operating system.
Computer software is used to perform tasks that humans would otherwise do:
Word processing – writing text with word processors such as Microsoft Word or OpenOffice Writer;
Spreadsheets – creating graphs and tables with spreadsheets such as Excel;
Presentations – creating slideshows with presentation software such as PowerPoint;
Datacenter
A datacenter is a large, powerful server that stores and processes large amounts of data. Data Centers are often found in large buildings or warehouses, but they can also be located near the end user.
Data centers are used for many different applications, including hosting websites and web servers, storing large amounts of information on storage devices (such as hard drives), processing transactions between customers and vendors through financial institutions like banks or credit card companies—and more!
Internet of things - the physical components of a computer system
The Internet of Things (IoT) is a term that refers to the physical components of a computer system. It can also be used to describe objects that are connected to the internet, whether they're mobile phones, email clients and so on.
ICT is often used in discussing new technologies that seek to better describe living and working conditions related to globalization and modern technological revolutions. For example:
Digital video recorders (DVR) are being replaced by cloud storage services such as Netflix's Watch Instantly service because it allows users access their videos anywhere at any time without installing software onto their computers or tablets (or smartphones).
Smartphones have become essential tools for both business professionals as well as consumers who have now switched from traditional landline phones due its convenience factor over cellular ones - this has led many companies offering phone plans where you can use your smartphone instead of paying an expensive monthly fee just for using it!
Electronic voting - the physical components of a computer system
Electronic voting is the use of computers in place of paper ballots. Electronic voting systems are often used in countries where there are no reliable polling places or vote-counting machines, such as Kenya, Lebanon and other countries in Africa.
The computer system has three main parts:
The central processing unit (CPU) which performs all calculations on data stored on hard disk drives or RAM memory. It also maintains control over inputs from other devices such as keyboards and mice that may be configured through software programs written by programmers who create new applications for specific purposes such as controlling cameras used during elections in India or tallying votes cast electronically at polling stations during elections in Nigeria.
Input/Output (I/O) circuitry that processes input signals from sensors such as those used by touch screens; converts these signals into digital signals that can be read by CPUs; controls output devices such as displays; sends commands back out into physical world via network connections between PCs connected through cables running across floors above ground level floors below ground level etcetera
E-commerce
The hardware and software that make up your computer system are what allow you to access and use information. They're also responsible for making sure your data is stored safely in the cloud, so you can access it from anywhere at any time on any device. The datacenter is the physical location where all this hardware lives (and dies). It's also where IT professionals maintain their servers, storage devices, network connections and other equipment needed to keep things running smoothly throughout your organization's operations.
An internet of things (IoT) refers specifically to connected devices that communicate via data networks such as Wi-Fi or cellular phone networks—but once these devices have been connected together using sensors such as cameras or microphones—they become part of an IoT network which includes both humans and machines interconnecting through communications protocols like Bluetooth Low Energy technology! From there we go into artificial intelligence (AI), which refers specifically here since AI involves machines learning from past experiences rather than being programmed with rules straight out of some textbook text book."
Artificial intelligence - the physical components of a computer system
Artificial intelligence (AI) is the field of computer science that focuses on creating intelligent machines. AI can be defined as a subfield of computer science that studies the possibility of creating intelligent machines, and it can be applied to many different tasks:
Speech recognition, which involves an artificial system learning how to understand human language by listening carefully
Robotics, where robots are programmed with rules about how they should behave in specific situations (for example, if a person says "go" then move forward two feet)
Telecommunications (e.g., mobile phones, e-mail, texting/SMS, instant messaging, blogging)
Telecommunications (e.g., mobile phones, e-mail, texting/SMS, instant messaging, blogging) is the transmission of signals over a distance by wire, radio, optical or other electromagnetic systems. The word telecommunications can refer to:
The system used to transmit messages over a network (telecommunication network)
The process of sending and receiving messages using electronic media such as computers and mobile devices
Health informatics (e.g., electronic health records, telemedicine)
Health informatics (e.g., electronic health records, telemedicine) is a field of study that focuses on the application of information science to health care. The term "health informatics" often refers to the intersection between healthcare and IT, but it can also refer to any other discipline or field where there are strong computer-related applications or technologies that affect human health.
Health Informatics is an interdisciplinary field that draws from many disciplines including computer science, engineering and medicine. It involves the design and development of new tools for improving healthcare delivery via data analysis; searching for patterns in large amounts of clinical data; developing algorithms that help make decisions about patient treatment based on individualized needs rather than just statistics alone; generating reports so doctors can understand how their patients' conditions were progressing over time during an illness episode (episodes).
Business information systems (e.g., enterprise resource planning, customer relationship management)
Business information systems (e.g., enterprise resource planning, customer relationship management) are computer software systems that are used to collect, store, process and present data in a format that can be used to manage business operations. Business information systems are often used to track sales, inventory and production data. In some cases they also provide access to financial information like budgets or cash flow projections based on historical trends established by previous years' data collection efforts.
ICT is often used in discussing new technologies that seek to better describe living and working conditions related to globalization and modern technological revolutions
ICT is often used in discussing new technologies that seek to better describe living and working conditions related to globalization and modern technological revolutions. These include new ways of organizing work, such as the use of flexible hours, teleworking arrangements and remote control technologies.
ICT has also been used to improve communication between individuals who do not live in the same place but share similar needs or interests. For example, online social networks allow people from different cultures to communicate with each other by posting messages that can be viewed by anyone with access (internet access).
ICT is often used in discussing new technologies that seek to better describe living and working conditions related to globalization and modern technological revolutions. It can also be used as a tool for improving health services, whether it be by providing more information for patients through smartphones or by enhancing their communication with doctors over longer distances using internet connections.
