Evolution of Computer Technology

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.

Your hard drives are what store all of your data, ranging from your operating system to your documents, music, and movies. If the RAM is your computer's short-term memory, your hard drive is the long-term memory. It stores the things you want to keep around for a while.

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.

Irregular Access memory is inside the PC which store the information and work with capacity memory to make lessen less and influence space for essential things to like record and documents in light of the fact that for individual protection.

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

Cache memory is the fastest memory outside of the CPU, runs at 10-30 ns per access.

a File or space on the hard drive where data from RAM is "swapped" in order to preserve space.

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

5. This chapter describes the concepts behind how a CPU reads the contents from RAM. Which of

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

Memory management exists in programs and applications, hardware, and in the Operating System (OS). In the Operating System, the OS goes to the hard drive, finding the piece of file or specific memory blocks, and then copies it into the RAM. The CPU is then able to access it. The OS must find a location in the RAM where it is not being used by anything else when it copies it from the hard drive.

c) A location in the computer’s memory that may contain different values at various times throughout the

The first ever computer was invented in the 1820s by Charlse Babbage. However the first electronic digital computer were developed between 1940 and 1945 in the United States and in the United Kingdom. They were gigantic, originally the size of a large room, and also need to be supply a large amount of power source which is equivalent as several hundred modern personal computers. The history of computer hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored program computers. The tools or mechanical tool used to help in calculation are called calculators while the machine operator that help in calculations is called computer. At first the

Computer data storage is also termed as memory. It is used for storing and processing information. In other words, it is used for archiving data in electromagnetic forms for use by a computer processor. It is a
