What is the memory of the drums?

Drum memory is a type of memory of a computer that used a design based on a drum to hold memory plates and units of reading; This was primarily used in the 1950s. To use the drum memory, the operators had to load the stock cards into each head and the programs would only work after all the punch cards were loaded. Later in the life of the drum memory, programmers discovered how to optimize the timing of the drum to facilitate memory loading. Unlike modern hard drive units, the drum contained reading-pisses for each plate, so there were no parts that would move the plates.

The memory memory unit was largely used in the 1950s, although it also recorded some use in the 1960s. Although this memory is largely lower, according to modern standards, it has been several advantages over earlier types of memory. It was easier to load the stocking cards, the memory worked several times faster and the unit itself was smaller than earlier typesmemoirs. This memory has become obsolete due to semiconductor memory, which has a better wars and storage.

There were several slots in the memory unit of the drum and each slot presented another plate for memory. To load the program or document, the operators had to place punch cards in these slots, one by one. If the stock cards were not loaded in the right slots, this could cause a problem to prevent the program or document from loading correctly. Punch cards are magnetic and this memory was made of ferromagnetic materials to help record memory.

At first, operators would load a stocking card into the drum memory and wait for the computer to recognize the memory before placing the next card. Later, operators were able to create programs that help optimize the load time. This program would estimate how long it will take to load the memory and when it was almost loadedAnd, someone was close to the memory ready to load another card. So many stocking cars of the basic application were needed to save time.

In modern memory units, such as semiconductor memory, there is only one head of reading and are programmed in memory to move so that the head can work with all plates at the same time. In the drum memory, the read-Write head was on the plate, so there was no need for the plates to move. This may seem more advanced, but it has increased memory costs, both in terms of memory and memory.
