Computers have changed the world in many ways. They allow huge amounts of information to be stored in a small space. They also allow a person to calculate mathematical problems with ease. Finally, computers allow people to communicate with one another through internet sites such as Facebook, My Space, and Twitter.

The main thing that allowed us to create personal computers were microchips. Microchips allowed us to store possessors and CPU components that would take up an entire room before the creation of them.

microprocessor

Although the development of digital computers is rooted in the abacus and early mechanical calculating devices, Charles Babbage is credited with the design of the first modern computer, the analytical engine, during the 1830s.

From hobby computers to Apple Computers small and inexpensive enough to be purchased by individuals for use in their homes first became feasible in the 1970s, when large-scale integration made it possible to construct a sufficiently powerful microprocessor on a single semiconductor chip.

The first mass produced personal computer was the Apple II, developed by Steve Jobs and Steve Wozniak.

A slow computer is often caused by too many programs running simultaneously, taking up processing power and reducing the PC’s performance. Click the CPU, Memory, and Disk headers to sort the programs that are running on your computer by how much of your computer’s resources they are taking.

random-access memory

Primary memory is the main memory of the computer system. Accessing data from primary memory is faster because it is an internal memory of the computer. The primary memory is most volatile which means data in primary memory does not exist if it is not saved when a power failure occurs.

RAM, which stands for random access memory, and ROM, which stands for read-only memory, are both present in your computer. RAM is volatile memory that temporarily stores the files you are working on. ROM is non-volatile memory that permanently stores instructions for your computer.

• Fastest memory is cache memory.
• Registers are temporary memory units that store data and are located in the processor, instead of in RAM, so data can be accessed and stored faster.

RAM stands for Random Access Memory. Physically, it is a series of chips in your computer. When your computer is turned on, it loads data into RAM. Programs that are currently running, and open files, are stored in RAM; anything you are using is running in RAM somewhere.

Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory. It is also called as read write memory or the main memory or the primary memory.

What is ROM? Read only memory (ROM) provides permanent storage for instructions needed during bootstrapping, or the process of turning on the computer. It does so by storing the BIOS and other firmware for the computer hardware.

RAM is random access memory and cannot hold the data without the power, whereas ROM is a read-only memory and can hold the data even without the power. With RAM, writing data is a much faster and lightening process, whereas ROM, writing data speed is much slower as compared to RAM.

Primary memory includes ROM and RAM, and is located close to the CPU on the computer motherboard, enabling the CPU to read data from primary memory very quickly indeed. It is used to store data that the CPU needs imminently so that it does not have to wait for it to be delivered.

RAM and ROM are both types of computer memory. RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. ROM stands for Read Only Memory.

There are basically two kinds of internal memory: ROM and RAM. ROM stands for read-only memory. It is non-volatile, which means it can retain data even without power.

Primary memory is computer memory that is accessed directly by the CPU. RAM is volatile memory, meaning it is erased when the power is turned off. Therefore, each time you start up your computer, the operating system must be loaded from secondary memory (such as a hard drive) into the primary memory, or RAM.

Read-Only Memory

A computer system is divided into two categories: Hardware and Software….Difference Between Hardware and Software.

Key difference: Hardware is the physical aspect of the computer, the thing we can touch, such as monitor, hard drive, etc. Software is the non-physical aspect which includes the operating system, applications, programs, etc. It is the code and instructions that tells the computer hardware how to operate.

Essentially, computer software controls computer hardware. These two components are complementary and cannot act independently of one another. In order for a computer to effectively manipulate data and produce useful output, its hardware and software must work together. Without software, computer hardware is useless.

Examples of hardware in a computer are the Processor, Memory Devices, Monitor, Printer, Keyboard, Mouse, and the Central Processing Unit….Difference Between Hardware and Software:
