The Manchester Baby was the first computer to run a program from memory, it ran its first program on June 21, 1948. The program was stored in a 32 word CRT based DRAM and consisted of 17 instructions; it ran for 52 minutes before reaching the correct answer of 131,072, after performing 3.5 million operations (for an effective CPU speed of 1.1 kIPS).
The modified ENIAC was the second computer to run a program from memory, it ran its first program as a stored-program computer on September 16, 1948. The program was stored in the 100 word Function Table ROM switches as 2 digit instructions (allowing storage for up to 500 instructions).

What does memory do on a computer?
It holds programs in its memory so you can multitask. Plus a program needs memory to be run. All computers need memory.
How can a computer with 64 Mega bytes of RAM run a program that is 512 Mega bytes in size?
First of all, it is not always necessary to have all of a program loaded into memory in order to run it. Second, all modern operating systems use a certain amount of hard disk space as a sort of temporary memory. This is known as "swap file" or "disk cache" and can greatly expand the capabilities of computer memory.
Why a PC needs to use ram?
Because it's the extra memory that helps the system go faster. RAM stands for Random Access Memory. It's the portion of the computer memory that is called upon to run whatever program you are using at the time. The more RAM a computer has, the faster and better it can run a program.
What is Function of loader in system software?
Whenever the assembly program is to be executed, it has to be assembled again; Programs ...loads the first program to be run by the computer -- usually an operating system ...
Which information is transferred from the punched tape to the flexible memory of the computer?
It can be anything, but mainly the program to run and/or the data required.
What does it mean when your computer says its taking a memory dump after running a program meant to search your computer for files?
It's just a way your computer "gathers itself up" after a huge memory loss. You probably have a program that takes alot of memory, and your computer is trying to find more to burn and waste. If you suddenly lose alot of memory, enough to NOT run programs, your computer will shut down, losing everything. That is why it tries to rebuild its memory so you don't haveta experience it's failure because you have a effin memory taking program. (no offence)
What are Outings?
A page out is when a page from memory is written to disk. If you have a program/application that needs alot of computer memory, the CPU can break up the program and run in memory the only part it currently needs. Once that part is finished it can be paged out and the next part paged in. Using the disk drive allows the computer to run larger jobs than those that would only fit into memory. Using the disk drive to swap out pages will cause the program to run slower. It's a trade off. Today's computer has much more memory that what was available in the past and the need for paging and swaping isn't as important as it once was. It is still used today.
What does it mean to run a program?
In computer terminology, "running a program" means copying a sequence of instructions from storage into main memory and initiating the execution or interpretation of those instructions.
Why does the computer slow down when more than one program is on?
A likely cause is that you have insufficient RAM. This means that your computer doesn't have enough simultaneous memory to run multiple or complicated programs. RAM memory only works when the computer is on and is used for storing short-term data while running programs. Also, there could be another fault with the computer that is causing the slowness which is undetectable from this location.
Would having a lot of memory on your graphics card make you computer run a lot faster on none graphic extensive program?
It will help it run faster yes.
If a program is using too much of system resources and bogging down?
The reason that a program is using too much memory is the way it is programmed or written. A solution to this is to quit or shut down the program and restart it. If there is still not enough memory then increasing the amount of memory on the computer will help. Another reason that a program is using too much memory is a virus is running on the computer. Like a human virus the computer virus is very bad news. There are still some computers that make it easy to catch a computer virus. Removing the virus will make the computer run much better.
