What are Technologies used for random access memory and serial access memory?

Very vague question. In terms of how RAM works: "SRAM" stores bits by using flip-flops. Higher-end "DRAM" memory stores bits in the form of a capacitor charge.

Name three serial access secondary storage device?
Random Access memory
Are SAM and RAM used in computer system?
Although these two acronyms can mean many things, the most common meanings with regard to computers are "random access memory" (or RAM), in contradistinction to "serial access memory" (or SAM). Each of these are ways to organize stored data in a computer.
Is RAM something referred to as involatile memory?
RAM stands for Random Access Memory. It does not specify whether it is volatile or non-volatile. RAM is just an access method just like SAM (serial access memory eg. magnetic tapes). The memory you are talking about is called primary memory of the computer which is semiconductor memory. Data can be stored in it as long as it is powered on since data is stored in the form of electric charge. Even Hard disks are RAM because you can randomly access any data from anywhere in the HDD
What are the different computer memory types?
The 5 types are: SIMM DIMM SODIMM SORIMM RDRAM The basic types are volatile memory such as RAM memory and 'permanent' memory such as hard drives USB, external drives and CD/DVDs
Difference between direct and sequential access?
RAM or Random Access Memory is used for fast computer memory. The word "Random" is a bit of a misnomer, as there is nothing random about access to this memory. What it actually means is that you can select an address at "random", that is, any address within the capability of the memory, and read or write data to/from that address just as fast as you could read or write data to any other address. In other words, data stored anywhere in the memory can be accessed quickly. Serial memory is different in that access time depends upon where on the medium the data is stored. Examples are magnetic tape, optical disk, magnetic disk. "arbitary access" is not a term used in electronics that I can find. I think it is just another term for "random access".
Why we are used RAM memory in our computer?
RAM, compared to other types of memory, is cheap to produce in large quantities and with large capacity, and reading from and writing to RAM chips are very fast operations compared to most other memory technologies.RAM also supports writing of very small quantities of data, and supports an infinite number of write operations. In comparison, some other memory technologies such as flash memory require blocks of several bytes or even kilobytes to be written at once, and support less than a million write operations until they wear out.The acronym RAM stands for random-access memory, a distinction shared with most modern alternative memory technologies. This distinguishes RAM from serial memory (such as on a tape), a distinction and advantage which is nearly irrelevant today.
Differences among sequential access direct access?
Let's say you have a set of 100 pieces of data, which are all names. Now, if you want to find a specific name, "Kevin", you can find it in different ways. You could either go through each of the records one after another, or you could randomly generate a number, and check if that record is "Kevin", this is potentially faster than sequential access as "Kevin" could be the last record.
What are the types of serial technologies?
Assuming that by serial technologies you mean serial communication, here are some: USB - Universal Serial Bus RS232C - The original serial protocol
Is magnetic tape a direct access storage medium?
Yes. In fact, it can only access data sequentially. Because tape is very inexpensive and will hold data fairly well for a long time, it's still in use even today, but memory access in sequence, not random, is much much slower. It's like having one-hundred 3x5 cards that you have information written on. Sequential memory is like having the hundred cards all stacked together and you can only access them by flipping through one at a time in order until you get to the card you want. Random memory is like having all the cards spread out on a big table so you can just go straight to the ones you want.
What are a few examples of memory for a computer?
Random Acccess Memory, Read Only Memory, Universal Serial Bus, Hard Disk. That is a few examples of what Mac people use that also work on Windows and Linux computers
What does the NVRAM in a Cisco switch store?
NVRAM is an acronym for Non-Volatile Random Access Memory. NVRAM is a type of Random Access Memory (RAM) that retains its information when power is turned off. The NVRAM is a small 24 pin DIP (Dual Inline Package) integrated circuit chip and is thus able to obtain the power needed to keep it running from the CMOS battery installed in your motherboard. It keeps track of various system parameters such as serial number, Ethernet MAC (Media Access Control) address, HOSTID, date of manufacture, etc. NVRAM is therefore a type of non-volatile memory that offers random access SYED OWAIS ALI{TECHNICAL SPECALIST}
What is memory mapping in microprocessor?
Memory mapping is the technique of assigning specific memory locations to specific capabilities. For example, the stack can be "mapped" or placed in memory (usually towards the high end of memory). The "heap" is often placed just below the stack. Not only are software constructs placed (mapped) into specific locations in memory, but peripherals can be mapped to memory as well. For example, a serial port may have several registers "mapped" into memory at specific locations. The means that if you want to send a message out the serial port, you would perform the same operation as you would writing to memory, except that you would provide the address of the write register of the serial port. In this way, peripherals appear exactly the same as memory. The technique replaces the older "port" access in which peripherals were accessed via a different set of signals. (basically a different address space which was access via the "port" command rather than the memory read/write).
