Information technology (IT) is the use of computers to create, process, store, retrieve, and exchange all kinds of electronic data and information. IT is typically used within the context of business operations as opposed to personal or entertainment technologies. IT is considered to be a subset of information and communications technology (ICT). An information technology system (IT system) is generally an information system, a communications system, or, more specifically speaking, a computer system — including all hardware, software, and peripheral equipment — operated by a limited group of IT users. 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 products or services within an economy are associated with information technology, including computer hardware, software, electronics, semiconductors, internet, telecom equipment, and e-commerce. Software is a collection of instructions that tell a computer how to work. This is in contrast to hardware, from which the system is built and which actually performs the work. The majority of software is written in high-level programming languages. They are easier and more efficient for programmers because they are closer to natural languages than machine languages. Computer hardware includes the physical parts of a computer, such as the case, central processing unit (CPU), random access memory (RAM), monitor, mouse, keyboard, computer data storage, graphics card, sound card, speakers and motherboard.

Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30. 3 million km2 (11. 7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20% of its land area. With 1. 3 billion people as of 2018, it accounts for about 16% of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19. 7, when the worldwide median age was 30. 4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita, in part due to geographic impediments, legacies of European colonization in Africa and the Cold War, predatory/neo-colonialistic activities by Western nations and China, and undemocratic rule and deleterious policies. Despite this low concentration of wealth, recent economic expansion and the large and young population make Africa an important economic market in the broader global context.
