What is RAM? | Random Access Memory Definition – Best Ram for laptop
Dear customer if you are finding the Definition of ram and if you are finding what is Ram? or any kind of information about rat you are on a write place we will give you the best ideas and information about ram so we are going to start the topic…
What is Ram?
Random Access Memory (RAM / ræm /) is computer memory that can be read in any order and is use to accurately store machine code and job data.   Access memory devices allow you to read or write data items at the same time, regardless of the physical location of the data in memory.
In contrast, with other directly accessible data storage media such as hard drives, CD-RW, DVD-RW, old magnetic islands, and drum memory, the time requires to read and write data is the rotation of the media and the recording of motion. from the arm. Media due to mechanical limitations, eg. Ex.
RAM has multiplexer and dematerializes circuitry to connect data lines to store addresses for reading or writing. In general, most of the storage is accesse at the same address, and RAM devices have multiple lines of data, often referre to as “8-bit” or “16-bit” devices. [Appointment necessary]
what is a ram in computer:
In today’s technology, flash memory takes the form of integrate circuit (IC) chips with MOS (metal oxide semiconductor) memory cells. RAM is generally associate with unstable memory types (such as dynamic random access memory (DRAM) encodings)
and stationary RAM is also generating, but store data is lost when the power is turne off.
The two main types of dynamic semiconductor random access memory are static random access memory (SRAM) and dynamic random access memory (DRAM).
Commercial use of semiconductor RAM dates back to 1965 when IBM introduce SP95 SRAM chips in System / 360 Model 95 computers and Toshiba use DRAM memory cells in Toussaint BC-1411 computers.
what is primary memory:
Both are base on bipolar transistors. MOS transistor-base commercial MOS memory was create in the late 1960s and has been the basis for all commercial semiconductor memories ever since. The first commercial DRAMATIC chip, the Intel 1103, was introduce in October 1970. Dynamic Invalid Access Coordinator
The 1MB chip is one of the last models develope by VEB’s Carl Zeiss Gina in 1989.
Early computers use relays, mechanical counters , or delay links for the main memory function.
Ultrasonic delay lines were saturate devices that could only return data in the order it was written. Drum memory can be expande at a relatively low cost, but making the memory material-efficient requires knowing the physical configuration of the drum to optimize speed.
what is a ram in computer:
The latches are made of tube triads and are then use separately from the separate transmitter for quick little memory, like registers. These registers were relatively large and very expensive to use for the data. In general, this type of memory can only provide tens or hundres of pieces.
The first practical form of random access memory was the William Tube, which was release in 1947. This data is store as a charged space on the surface of the cathode tube.
The memory was in random access because the CRT electron beam could read and write places in any order in the tube. Williams tubes had capacities of hundres to thousands of caps but were much smaller, faster, and more powerful than individual tube closures.
Found at the University of Manchester in England, Williams Tube provides the means to implement the first electronically store the program on a Manchester Baby computer, which was first release on June 21, 1948.

] In fact, tube memory Williams was not design for the baby, but the baby was test to show the validity of memory. ] ]
The original magnetic memory was invent in 1947 and develop until the 1970s.
It is a popular form of manually accessible memory, depending on the configuration of the magnetic rings. By changing the magnetic meaning of each ring, something can be store for each ring to store data.
Each circle had a combination of address strings to choose from to read or write. So it was possible to reach any part of memory in any order. Magnetic-core memory. Was the standard in computer memory system until it replaces solid-state MOS (silicon oxide) semiconductor memory in composite circuits (ICs).
