How does a programmer use digital waves to transfer sound?

1 answer:

7 0

An analogue sound wave is picked up by a microphone and sent to an Analogue to Digital (ADC) converter in the form of analogue electrical signals. The ADC converts the electrical signals into digital values which can be stored on a computer. Once in a digital format you can edit sounds with programs such as audacity.

Explain the developments RAM since it was created in 1968 til today.

xenn [34]

Answer:

From DRAM to DDR4

Explanation:

RAM stands for Random Access Memory. 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 "Phase - change memory - PRAM - ". 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.

The area that holds all the instructions the computer needs to start up when it is powered on is ________.

stepan [7]

The area that holds all the instructions the computer needs to start up when it is powered on is b) ROM

Further Explanation:

RAM and ROM are the types of memory. RAM is the active memory. The data can be read and written from RAM. While ROM is read only which meas that data or instructions on ROM cannot be changed.

The files or instructions that are needed to start up a computer are usually unchangeable as they always have to be the same. These type of instructions are stored in ROM. When he computer is turned on, the instructions needed to start the computer are loaded into the main memory from the ROM.

Hence, ROM is the correct answer.
