![]() ![]() ![]() 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 ![]()
