Volatile memory is computer memory that requires power to maintain the stored information. Secondary memory is called virtual memory. Storage which are slow to access but offer higher memory capacity. RAM), as a distinction from secondary memory, which are physical devices for program and data The term primary memory is used for the information in physical systems which are fast (i.e. On a temporary or permanent basis for use in a computer or other digital electronic device. It refers to the physicalĭevices used to store programs (sequences of instructions) or data (e.g. It facilitates the remembrance power to computer system. The CPU (Central Processing Unit) is the device that Performs arithmetic and logic operations. Referred to as the Central Processing Unit (CPU). The main component to make a computer operate is the computer chip or microprocessor. Those devices which help to display the processed information.Eg.

Mouse, Touch screen,Bar Code Reader, Scanner, MICR, OMR etc.

Those devices which help to enter data into computer system. Quantum computation and molecular and nanotechnology will radically change the face of Of parallel processing and superconductors is helping to make artificial intelligence a reality. Though there are some applications, such as voice recognition, that are being used today. The Fifth Generation (Present & Beyond):įifth generation computing devices, based on artificial intelligence, are still in development, There is great development in data communication. TheĬomputers using this technology known to be Micro Computers. As a result microprocessors came into existence. Level languages invented in this generation. These computers were smaller, faster & more reliable. Small scale integrated circuits which had 10 transistors per chip, technology developed to MSI circuits with 100 transistors per chip. The 3 rd generation computers replaced transistors with Integrated circuit known as chip. The first operating system developed in this generation. This generation computers generated less heat & were They required onlyġ/10 of power required by Vacuum tubes. In 2 nd generation computers, Vacuum tubes were replaced by Transistors. Some computers of this generation are ENIAC, EDVAC,ĮDSAC& UNIVAC-1. TheĮlectricity consumption was very high. These computer were large in size & their programming was difficult task. The first generation computers used Vacuum tubes & Machine language was used for giving the Generations of computer: First Generation (1940-56):

Persons or the users, using Computers in day to day activity are known as liveware. Instructions written/embedded on a hardware are known as firmware e.g., BIOS instruction on

Software is a set of instructions or a program that enables a hardware to run. In other words all theĬomponents that we can touch come under the category of Hardware eg Keyboard, Mouse Software HardwareĪll the physical and tangible components of Computer are called Hardware. Software gives 'intelligence' to the computer. Hardware = Internal Devices + Peripheral DevicesĪll physical parts of the computer (or everything that we can touch) are known as.COMPUTER SYSTEM = HARDWARE + SOFTWARE+ USER
