The first Pentium computer.
pentium 1 was invented in 1993
A computer can hold memory depending on how strong the motherboard and the processor is. For example you have a Pentium 1 computer, obviously you cannot afford to put a 1GB memory on it.
Pentium 1s are processors. They don't have memory.
Pentium I processors are CISC.
Yes.
About maybe 1-3 GB.
Series of processors / Generation of Pentium processors.
No. There is no possible upgrade for a computer with a 120 MHz Pentium to an 800 MHz processor. You couldn't even replace the motherboard, as the case would not support newer motherboards (AT/Baby AT vs. ATX/microATX)
Slot 1 motherboards were primarily designed for the Pentium II and early Pentium III processors. A Pentium Pro could be used with a special converter known as a "slotket." Later Pentium III processors could be retrofitted to work on Slot 1 boards with a similar slotket.
The company is Intel
Are you wondering what the sticker looked like on the box? It was just the blue word Pentium basically.
