Computers Controlers and Devices: Ram and Transfer in Process

RAM: RAM stands for Random Access Memory. It is a bit like a person's short-term memory. RAM is volatile so data only exists only when the computer is turned on, and is used by the operating system and other applications.

RAM (Random Accesses Memory): RAM is used by CPU when a computer is running to store the information that it needs to be used very quickly but it does not store any information permanently.

There once was a young computer named Mac, whose job was to gather, process, output, and store data and information. He was born in 2013 and contained 4 gigabytes also known as 4 billion bytes on his RAM. He used He lost both of his parents when they were sold from best buy, so now his is on his own trying to figure out his life and how to do his job. He had a few memories of his parents on is RAM or his random access memory, but that was only a part of his temporary memory.

Memory refers to the processes that are used to acquire,store,retain and later retrive information. There are three major processes involved in memeory ; encoding,storage,retrieval.

Random Access Memory (RAM) - the storage of data and instructions inside the primary storage is temporary. It disappears from the RAM as soon as the power to the computer is

List and describe at least three types of storage that is typically included in all computer systems.

CPU : This is the central processing unit, better known as the processor. This is the heart of the PC where calculations are madeRAM: RAM stands for random access memory. This part in the PC grabs the file from the hard drive and stores on its non permanent memory so that you can have multiple windows open such as word and be able to access this data faster. The more RAM the faster and more apps you can open and the bigger the files the ram can hold. However, if you are using word and your pc crashes and you haven’t saved the file to the hard drive. The work that you have done will be lost due to that RAM does not hold on to files. GPU(Graphics card): The graphics

Cache is a volatile form of storage meaning when the computer is turned off, then the data is lost. Cache cost a lot of money to make meaning it has got a higher cost per byte than ram or flash storage. The reason cache is used for storing frequently instructions near or on the CPU is because it's faster than ram and has less latency, but has a higher capacity than registers at a lower but still high cost compared to other types of storage. In conduction is that cache is a high speed form of temporary storage, which acts as a buffer between the ram and the CPU, which stores frequently used instructions which removes the speed decrease from using the system buses and has low latency and cost less than registers and has a higher

When we talk about an on-disk backing store, we usually mean the virtual memory allocated to the physical memory. This virtual memory acts like a ‘backup’ in case we require a little extra physical memory to handle the execution of the active process(es). This memory is usually slower than our RAM, however performance can be optimized by ensuring that only those parts or pages of the process that are active are kept in physical memory. This does agree with the Iron Laws of Memory Hierarchy. RAM is fast and expensive and is used in smaller amounts, while the on-site backing store is usually larger but slow.

Main memory unit:It is called as temporary store house of the computer which stores data and programs .It is typically called volatile memory.(when the computer is shut down,the contents of the memory are lost,it is also called primary memory.

Random Access Memory (RAM) allows data to be stored on the computer for a short period of time. When the computer shuts down all the memory is lost; this means when the computer is turned on, there will be more room for data to be stored.

This information and instructions for the CPU are stored in Random Access Memory (RAM). This memory is the next hardware component for a bare bones PC referred to as the main memory. The CPU has direct access to any instructions for programs to be executed that are in the main memory and only in the main memory. The main memory is volatile which means it can only store data or instructions when the computer is powered on. The device that stores data when the PC is powered off is the hard drive. It is the computers primary method of storage. Another way it stores memory is through the floppy drive. This form of memory is removable.

The control unit of the CPU contains circuitry that uses electrical signals to direct the entire computer system to carry out, stored program instructions. The control unit does not execute program instructions; rather, it directs other parts of the system to do so. The control

RAM is an acronym for Random Access Memory. It’s a memory module in the computer which stores data temporarily in the RAM instead of in the hard drive. Ram is a type of volatile memory - without electricity, RAM is empty. A larger size of RAM enables the computer to run more program simultaneously instead of paging (The process of running the program from the hard drive to the Ram). RAM size affects in playing games. A game with large file size generally requires large amount of memory available in order to have a smooth gameplay. Without enough RAM, the Game Performance will be affected and can cause a drop in framerate or can crash the games. A decent RAM size required to run a smooth game is around 8GB, but to get the best result is around 16GB of memory.
