Answer:
$2.40
Explanation:
the unit electricity bill is kilo watt hour.
The 60-watt light bulb has a 400 hour life expectency means it will consume
60×400/1000 = 24 KWh units of electricity. Let us suppose each unit of electricity costs is 10 cents.
Then 24×10 = 240 cents = $2.40
Answer:
From DRAM to DDR4
Explanation:
RAM stands for <em>Random Access Memory.</em> In 1968, Mr. Robert Dennard at IBM's Watson Research obtained the patent for the one-transistor cell that will eventually substitute the old magnetic core memory allocated in computers of the time. By 1969 Intel released the TTL bipolar 64-bit SRAM (Static Random-Access Memory) as well as the ROM "Read Only Memory"; also in 1969 it evolved into "<em>Phase - change memory - PRAM - </em>". However this evolution was not commercialized, Samsung expressed its interest in developing it. In 1970 the first DRAM product was commercially available; it was developed by Intel. In 1971 it was patented EPROM; in 1978 George Perlegos developed EEPROM.
By 1983 a nice breakthrough happened with the invention of SIMM by Wang Labs. In 1993 Samsung came up with KM48SL2000 synchronous DRAM (SDRAM), this variation soon turned into an inductry standard.
In 1996 DDR began a revolution in the memory sector, then in 1999 RDRAM. Both DDR2 SDRAM. DDRR3 and XDR DRAM were commercialized. Finally in 2007 and 2014 the developments of DDR3 and DDR4 were available for the general public.

Answer:
Learning opportunities for AI can be extended to all through the inclussion of courses and different teaching methods related to Artificial Intelligence, new technologies, computer science, programming and, in short, everything related to the digital world, in the educational plans at the national level. This is so because artificial intelligence and computer systems are the basis for the development of the new tools jobs of tomorrow. Thus, education in these subjects is essential so that citizens can enter the labor market once they acquire the necessary age, having the knowledge to do so in a proper way.
