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:
The correct option is D: Control Bus
Explanation:
A control bus is usually used by the Central Processing Unit to communicate with all the devices that are connected or contained within a computer. This connections are usually done via physical connections such as printed circuits or cables. It is also called a Computer bus and helps in coordinating activities between the connected devices.
Available options
=A4&&B4
=A4&" "&B4
="A4"&""&"34"
=A4&""&B4
Answer:
=A4&""&B4
Explanation:
In a Microsoft Excel spreadsheet, to combine the content of two cells into another cell, a user will have to use the command &
Hence, in this case, given that there is no need to have any character or blank space in between the content of the starging cells, which is just A4 and B4, then we have the following technique
1. Select the cell C2
2. Input the command = or +, then select cell A4
3. Input the command &
4. Then select the cell B4
5. Click enter.
Therefore, the answer should appear as =A4&B4.
But from the available options, there is nothing like that, so we pick =A4&""&B4 because it gives the same outcome.
