What was the RAM size first computer have?
When was the first computer invented?
There is no simple response to this inquiry on account of the apparent multitude of various characterizations of PCs. The principal mechanical PC made by Charles Babbage doesn't generally take after what most would think about a PC today. Hence, this record has been made with a posting of every one of the PC firsts beginning with the Difference Engine and paving the way to the sorts of PCs we use today. Remember that early developments that helped pave the way to the PC, for example, the math device, number cruncher, and tablet machines are definitely not represented in this report.
The word "computer" was first used
"Computer" was first recorded as being utilized in 1613 and was initially was utilized to portray a human who performed counts or calculations. The meaning of a PC continued as before until the finish of the nineteenth century when individuals started to acknowledge machines never get drained and can perform estimations a lot quicker and more precisely than any group of human PCs actually could.
First mechanical computer or automatic computing engine concept
In 1822, Charles Babbage conceptualized and started building up the Distinction Motor, viewed as the primary programmed registering motor that was fit for figuring a few sets of numbers and making printed copies of the outcomes. Lamentably, in view of financing he was always unable to finish a full-scale utilitarian variant of this machine. In June of 1991, the London Science Gallery finished the Distinction Motor No 2 for the bicentennial year of Babbage's introduction to the world and later finished the printing component in 2000. Afterward, in 1837 Charles Babbage proposed the primary general mechanical PC, the Logical Motor. The Expository Motor contained a Math Rationale Unit (ALU).
First ideas of what we think about a modern PC
The Turing machine was first proposed by Alan Turing in 1936 and turned into the establishment for speculations about figuring and PCs. The machine was a gadget that printed images on paper tape in a way that imitated an individual adhering to a progression of sensible directions. Without these basics, we wouldn't have the PCs we use today.
The first digital computer
Short for Atanasoff-Berry PC, the ABC began being created by Teacher John
Vincent Atanasoff and graduate understudy Precipice Berry in 1937 and kept on being created until 1942 at the Iowa State School (presently Iowa State College). The ABC was an electrical PC that pre-owned vacuum tubes for advanced calculation including parallel math and Boolean rationale and had no central processor. On October 19, 1973, the US Government Judge Baron R. Larson marked his choice that the ENIAC patent by J. Presper Eckert and John Mauchly was invalid and named Atanasoff the designer of the electronic advanced PC. The ENIAC was created by J. Presper Eckert and John Mauchly at the College of Pennsylvania and started development in 1943 and was not finished until 1946. It involved around 1,800 square feet and utilized around 18,000 vacuum tubes, weighing just about 50 tons. In spite of the fact that the Adjudicator decided that the ABC PC was the primary computerized PC, some still believe the ENIAC to be the main advanced PC since it was completely practical.
What was the RAM size which the first computer have ??
In 1910, Henry Babbage, Charles Babbage's most youthful child had the option to complete a bit of this machine and had the option to perform fundamental estimations.The primary PC I possessed had 16.25K of RAM. 16384 + 256 bytes of RAM, of which just 256 bytes were computer processor addressable. The rest was video memory.

On April 7, 1953 IBM openly presented the 701, its first electric PC and first mass created PC. Later IBM presented its first PC called the IBM PC in 1981. The PC was code named and still once in a while alluded to as the Oak seed and had a 8088 processor, 16 KB of memory, which was expandable to 256 and used MS-DOS.
The first microprocessor
Intel presents the primary microchip, the Intel 4004 on
November 15,1971.
The primary PC or first Laptop
The IBM 5100 is the primary compact PC, which was delivered on September 1975. The PC weighed 55 pounds and had a five inch CRT show, tape drive, 1.9MHz PALM processor, and 64KB of Slam. In the picture is a promotion of the IBM 5100 taken from a November 1975 issue of Logical America. The principal really versatile PC or PC is considered to be the Osborne I, which was delivered on April 1981 and created by Adam Osborne. The Osborne I weighed 24.5 pounds, had a 5-inch show, 64 KB of memory, two 5 1/4" floppy drives, ran the CP/M 2.2 working framework, included a modem, and cost US$179. The IBM PC Division (PCD) later delivered the IBM convenient in 1984, it's first compact PC that tipped the scales at 30 pounds. Later in 1986, IBM PCD declared it's first PC PC, the PC Convertible, gauging 12 pounds. At last, in 1994, IBM presented the IBM ThinkPad 775CD, the principal scratch pad with an incorporated Disc ROM.
The first Apple computer
Steve Wozniak designed the first Apple, known as the Apple I, in 1976.
Other significant PC organization firsts
The following is a posting of a portion of the significant PCs organizations first PCs. Compaq - In Walk 1983, Compaq delivered its first PC and the principal 100% IBM viable PC the "Compaq Convenient." Dell - In 1985, Dell presented its first PC, the "Turbo PC." Hewlett Packard - In 1966, Hewlett Packard delivered its first broad PC, the "HP-2115." NEC - In 1958, NEC manufactures its first PC the "NEAC 1101." Toshiba - In 1954, Toshiba presents its first PC, the "TAC" computerized PC.
