The first IBM PC had an Intel 8088 processor, 64KB of RAM (extendible to 256KB), a floppy disk drive (which could be used to boot the computer with a rebranded version of MS-DOS (PC-DOS)), and a CGA or monochrome video card. The machine also had a version of Microsoft BASIC in ROM.

How much RAM was the first computer?
Four kilobytes of RAM. My first computer was a TRS-80 Model 1. Later I got an Expansion Interface for it, which added the ability to connect floppy drives (before that, it stored programs on cassette tape), and boosted the RAM to a whopping, mind-blowing 32 KB.
Did the first computer have RAM?
Konrad Zuse completed the Z22, the seventh computer model and the first computer that used magnetic storage memory. MIT introduced the Whirlwind machine on March 8, 1955, a revolutionary computer that was the first digital computer with magnetic core RAM.
What is the most RAM a computer has ever had?
Hewlett Packard Enterprise said it has built the world’s largest single-memory computing system in the world consisting of 160 terabytes (1 terabyte equals 1,000 gigabytes).
How much RAM did the first laptop have?
8 kilobytes
Initial specifications included 8 kilobytes of RAM (expandable to 24 KB) and a 3 MHz processor. The machine was in fact about the size of a paper notebook, but the term had yet to come into use and it was generally described as a “portable” computer.
Who created RAM?
Robert Heath Dennard
Dennard. Robert Heath Dennard invented one-transistor Dynamic Random Access Memory (DRAM), which allowed major increases in computer memory density and decreases in cost. It became the standard of the industry for RAM and enabled the microcomputer revolution.
How much RAM did computers have in 1985?

When was RAM first used?
1947
The first form of RAM came about in 1947 with the use of the Williams tube. It utilized a CRT (cathode ray tube); the data was stored on the face as electrically charged spots. The second widely used form of RAM was magnetic-core memory, invented in 1947.
What are the 3 types of RAM?
Although all RAM basically serves the same purpose, there are a few different types commonly in use today:
- Static RAM (SRAM)
- Dynamic RAM (DRAM)
- Synchronous Dynamic RAM (SDRAM)
- Single Data Rate Synchronous Dynamic RAM (SDR SDRAM)
- Double Data Rate Synchronous Dynamic RAM (DDR SDRAM, DDR2, DDR3, DDR4)

Is 1TB of RAM possible?
Many servers have around 1 – 4 terabytes of ECC-RAM. Presently the highest amount of RAM in a single stick is around 32 gigabytes for personal computers and it would take 32 sticks of such RAM to make up one terabyte of RAM. So it is possible but not today.
How much RAM does a NASA computer have?

Is 1TB RAM overkill?
1024 GB or 1 TB of RAM is definitely overkill for the vast majority of uses. There are certainly contexts where it’s useful (large in-memory databases for example) but for most people it would just be a big waste of money.
