What was the first storage device?
The Williams-Kilburn Tube
, invented in 1947, featured the first fully electronic form of data storage. The device was 16 1⁄2 inches long, 6 inches wide, and stored data by displaying a grid of dots on cathode ray tubes, and sending a static charge through the tubes.
Which is the fastest storage device?
Seagate
today announced what it’s calling the world’s fastest enterprise-class, solid-state drive (SSD), one that can transfer data at rates up to 10 gigabytes per second (GBps), some 6GBps faster than its previously fastest SSD.
What is Ram in memory?
RAM stands for
random-access memory
, but what does that mean? Your computer RAM is essentially short term memory where data is stored as the processor needs it. … RAM can slow down your computer if there isn’t enough of it for the processor to perform the tasks you ask it to.
What are the 2 types of RAM?
- DRAM (pronounced DEE-RAM), is widely used as a computer’s main memory. …
- SRAM (pronounced ES-RAM) is made up of four to six transistors.
What is RAM example?
Examples include
DRAM, SDRAM, DIMM, SO-DIMM and VRAM
, as well as terms such as DDR3 and GDDR5. DRAM and SDRAM are simply more specific terms for the RAM that you’ll find in a modern computer (technically, SDRAM, Synchronous Dynamic Random-Access Memory, is more accurate).
What is RAM and ROM with example?
RAM and ROM are both types of
computer memory
. RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. ROM have prerecorded data and it is used to boot computer. … ROM stands for Read Only Memory.
