WRITE THE FOLLOWING ACRONYMS IN FULL
Artificial intelligence (AI) is a branch of computer science that emphasizes on the design and creation of intelligent machines that work, behave and respond like humans. Some of the characteristics that AI emphases on include: Speech recognition, Learning, visual perception, logical and arithmetic analysis and translation between languages.
Information and Communication Technology
Information and communication technology (ICT) is an advancement term for information technology (IT) that emphises on the technologies that provide access to information through the integration of telecommunications (telephone lines and wireless signals) and computers, as well as necessary enterprise software, middleware, storage, and audiovisual systems, that enable users to access, store, transmit, and manipulate information.
Electronic Numerical Integrator And Computer
In 1942, physicist John Mauchly and John Presper Eckert proposed an all-electronic calculating machine. The result was ENIAC (Electronic Numerical Integrator And Computer), built between 1943 and 1945 — the first large-scale computer to run at electronic speed without being slowed by any mechanical parts. ENIAC was designed and primarily used to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory, its first program was a study of the feasibility of the thermonuclear weapon. In 1953, the Burroughs Corporation built a 100-word magnetic-core memory, which was added to the ENIAC to provide it with memory capabilities. By 1956, the end of its operation, the ENIAC occupied about 1,800 square feet and consisted of almost 20,000 vacuum tubes, 1,500 relays, 10,000 capacitors, and 70,000 resistors. It also used 200 kilowatts of electricity, weighed over 30 tons, and cost about $487,000.

Uninterruptible Power Supply
This is an Uninterruptible Power Supply. It cleans power as it enters into the computer by eliminating power surges and brownouts, it alerts the user when power goes off by producing a beeping sound and also keeps power to power the computer shortly after blackout so that the computer user can be able to save his/her work.
