Generations of Computers – Computer Fundamentals

Generations of Computer : The modern computer took its shape with the arrival of your time. It had been around the 16th century when the evolution of the computer started. The initial computer faced many changes, obviously for the betterment. It continuously improved itself in terms of speed, accuracy, size, and price to urge the form of the fashionable day computer. 

Basic Terms Related to Computers

The basic terms related to generations of computers are listed below.

  • Vacuum Tube: Vacuum tubes have the functionality of controlling the flow of electronics in a vacuum. Generally, it is used in switches, amplifiers, radios, televisions, etc.
  • Transistor: A transistor helps in controlling the flow of electricity in devices, it works as an amplifier or a switch.
  • Integrated Circuit (IC): Integrated circuits are silicon chips that contain their circuit elements like transistors, resistors, etc.
  • Microprocessors: Microprocessors are the components that contain the CPU and its circuits and are present in the Integrated Circuit.
  • Central Processing Unit (CPU): The CPU is called the brain of the computer. CPU performs processing and operations work.
  • Magnetic Drum: Magnetic Drum is like a cylinder that stores data and cylinder.
  • Magnetic Core: Magnetic cores are used to store information. These are arrays of small rings.

  • Memory: Memory is used to store data, information, and program in a computer.
  • Artificial Intelligence: Artificial Intelligence deals with creating intelligent machines and behaviors.

Phases of Computer Generations

This long period is often conveniently divided into the subsequent phases called computer generations.

  • First Generation Computers (1940-1956)
  • Second Generation Computers (1956-1963)
  • Third Generation Computers (1964-1971)
  • Fourth Generation Computers (1971-Present)
  • Fifth Generation Computers (Present and Beyond)

Before the generation of computers, we used calculators, spreadsheets, and computer algebra systems, mathematicians and inventors searched for solutions to ease the burden of calculation. 

Below are the 8 Mechanical Calculators before modern computers were invented.

  •  Abacus (ca. 2700 BC)
  • Pascal’s Calculator (1652)
  • Stepped Reckoner (1694)
  • Arithmometer (1820)
  • Comptometer (1887) and Comptograph (1889)
  • The Difference Engine (1822)
  • Analytical Engine (1834)
  • The Millionaire (1893)

First Generation Computers

The technology behind the primary generation computers was a fragile glass device, which was called a vacuum tube. These computers were very heavy and really large. These weren’t very reliable and programming on them was a tedious task as they used low-level programming language and used no OS. First-generation computers were used for calculation, storage, and control purpose. They were too bulky and large that they needed a full room and consume a lot of electricity. Punch cards were used for improving the information for external storage. Magnetic card used . Machine and assembly language is developed.

Examples of some main first-generation computers are mentioned below.

  • ENIAC: Electronic Numerical Integrator and Computer, built by J. Presper Eckert and John V. Mauchly was a general-purpose computer. It had been cumbersome, and large, and contained 18,000 vacuum tubes.
  • EDVAC: Electronic Discrete Variable Automatic Computer was designed by von Neumann. It could store data also as instruction and thus the speed was enhanced.
  • UNIVAC: Universal Automatic Computer was developed in 1952 by Eckert and Mauchly.

Characteristics of First-Generation Computers

Second generation computers.

Second-generation computers used the technology of transistors rather than bulky vacuum tubes. Another feature was the core storage. A transistor may be a device composed of semiconductor material that amplifies a sign or opens or closes a circuit.

Transistors were invented in Bell Labs. The use of transistors made it possible to perform powerfully and with due speed. It reduced the dimensions and price and thankfully the warmth too, which was generated by vacuum tubes. Central Processing Unit (CPU), memory, programming language, and input, and output units also came into the force within the second generation.

The programming language was shifted from high level to programming language and made programming comparatively a simple task for programmers. Languages used for programming during this era were FORTRAN (1956), ALGOL (1958), and COBOL (1959).

Characteristics of Second-Generation Computers

Third generation computers.

During the third generation, technology envisaged a shift from huge transistors to integrated circuits, also referred to as IC. Here a variety of transistors were placed on silicon chips, called semiconductors. The most feature of this era’s computer was speed and reliability. IC was made from silicon and also called silicon chips.

The computer programs was designed to make the machine work. Operating system was a program designed to handle a machine completely. Because of the operating system machine could execute multiple jobs simultaneously. Integrated circuits were used to replace many transistors used in the second generation.

A single IC has many transistors, registers, and capacitors built on one thin slice of silicon. The value size was reduced and memory space and dealing efficiency were increased during this generation. Programming was now wiped out Higher level languages like BASIC (Beginners All-purpose Symbolic Instruction Code). Minicomputers find their shape during this era.

Integrated Circuit

Characteristics of Third-Generation Computers

Fourth generation computers.

In 1971 First microprocessors were used, the large-scale of integration LSI circuits built on one chip called microprocessors. The advantage of this technology is that one microprocessor can contain all the circuits required to perform arithmetic, logic, and control functions on one chip. LSI placed thousands of transistors onto a single chip.

The computers using microchips were called microcomputers. This generation provided even smaller size of computers, with larger capacities. That’s not enough, then Very Large Scale Integrated (VLSI) circuits replaced LSI circuits. The Intel 4004 chip, developed in 1971, located all the components of the pc from the central processing unit and memory to input/ output controls on one chip and allowed the dimensions to reduce drastically. VLSI placed several hundred thousand transistors on a single silicon chip. This silicon chip is known as the micro processor.

Technologies like multiprocessing, multiprogramming, time-sharing, operating speed, and virtual memory made it a more user-friendly and customary device. The concept of private computers and computer networks came into being within the fourth generation.

Fifth generation computers.

The technology behind the fifth generation of computers is AI. It allows computers to behave like humans. It is often seen in programs like voice recognition, area of medicine, and entertainment. Within the field of game playing also it’s shown remarkable performance where computers are capable of beating human competitors.

The speed is the highest, size is the smallest and area of use has remarkably increased within the fifth generation computers. Though not a hundred percent AI has been achieved to date but keeping in sight the present developments, it is often said that this dream also will become a reality very soon.

To summarize the features of varied generations of computers, it is often said that a big improvement has been seen so far because of the speed and accuracy of functioning care, but if we mention the dimensions, it’s been small over the years. The value is additionally diminishing and reliability is increasing.

Generations of Computer PPT, PDF Report

First Generation (1945- 1955):

Some of the first generation computers were ENIAC, EDSAC, EDVAC, and UNIVAC. Where

  • ENIAC – Electronic Numerical Integrator And Calculator
  • EDSAC – Electronic Delay Storage Automatic Calculator
  • EDVAC – Electronic Discrete Variable Automatic Computer
  • UNIVAC – Universal Automatic Computer IBM 701

In all the above computers, the vacuum tube technology was used and the computational speed was in milliseconds but they were non-portable, not reliable, highly susceptible to hardware failures, very expensive, consume a huge amount of electricity, has to need to assemble every component manually. So, because of all the above reasons, the commercial production was very poor. They also had difficulty to avail as they were machine language dependent.

Second Generation (1955- 1965):

The examples of second generation computers are IBM- 1401, IBM- 7090, IBM- 7030, Digital data corporation’s PDP 1/5/8, Honey well 400.

In this generation vacuum tubes were replaced by the transistors (invented at bell laboratories). These machines were comparatively small in size when compared to the first generation machines. The computational speed was very high i.e. from milliseconds to microseconds and they use to generate fewer amounts but still air conditioning was required. They were portable, reliable and not susceptible to the failures of hardware. They required manual assembling of components to form a functional unit and were assembly language dependent as compilers were developed to change from high-level language to assembly language program.

They were low in cost, magnetic ferrite core memories were used as main memory and magnetic tapes as secondary memory. Improvement of the individual input and output memories helped to operate in parallel with the CPU. They had the wide range of application in many fields like business to the engineering analysis and design.

Third Generation (1965- 1975):

Illustration of the third generation computers was system 360 mainframe from IBM, PDP-8, Mini computers from digital equipment corporation, NCR 395 and B6500.

The computers of the third generation were based on the integrated circuit technology, the central processing unit; input/output processors were equipped by small scale integration and medium scale integration. They were smaller in size, generates less amount of heat, computational speed was very fast (i.e. from microseconds to nanoseconds), low maintenance cost as not prone to hardware failure. In the commencing magnetic core memories were in avail but later semiconductor memories (RAM & ROM) were used in their place.

Only during this generation microprogramming, parallel processing, database management, multi-user application, automatic industrial control and much more were introduced.

Fourth Generation (1975- Present):

During this generation the microprocessors were introduced, the microprocessor is a stamp size chip which has a complete circuit of a computer processor using VLSI. Few integrated circuits with the entire circuitry are Intel’s (8088, 80286, 80386, 80486), Motorola’s (68000, 68030, 68040), Apple II, CRAY I/2/X/MP, Altair 8800 and CRAV-1.

In this semiconductor chips played the role of main memory whereas hard disks are used as secondary memory and floppy disks are used backup memory. They were small in size, have high speed, cheaper in cost, portable, and reliable. These machines don’t generate much heat, have low maintenance cost and low production cost. C language, Graphical user interface, Unix OS were also introduced.

Also See: Grid Computing Seminar and PPT with PDF Report

Fifth Generation (Present and Beyond):

The characteristics found in fifth generation computers are

  • Artificial Intelligence
  • Parallel Processing
  • Multiple Pipelines and Multiple Processors

Artificial Intelligence:  Artificial Intelligence refers to the sequence of inter-related technology that generally simulate and reproduce human behavior which includes thinking, speaking and listening.

Parallel Processing:  In contrast to serial processing, parallel processing executed several instructions simultaneously at a single operation. 

Mega Chips:  these generation computers will use super large integrated chips as they require a large amount of storage for storing information as well as instructions.

Ultra Large Scale Integration technology was implemented in the Intel’s Pentium 4 microprocessor. Also, vector processors, SIMD processors, memory chips, hard disks up to 180 GB, object-oriented languages and new operating systems have been developed.

Some of the examples of the fifth generation computers are SUN workstations, Origin 2000, PARAM 10000, IBM SP/2, IBM notebooks, Pentium PCs-Pentium 1/2/3/4/Dual core/Quad core and much more.

           Hence, the generations of the computers explain in detail about the past and further development of technology. Coming technologies like quantum mechanism, nanotechnology will change the stage of computers and grid technology is the upcoming technology in the internet application.

Title: sv3d: novel multi-view synthesis and 3d generation from a single image using latent video diffusion.

Abstract: We present Stable Video 3D (SV3D) -- a latent video diffusion model for high-resolution, image-to-multi-view generation of orbital videos around a 3D object. Recent work on 3D generation propose techniques to adapt 2D generative models for novel view synthesis (NVS) and 3D optimization. However, these methods have several disadvantages due to either limited views or inconsistent NVS, thereby affecting the performance of 3D object generation. In this work, we propose SV3D that adapts image-to-video diffusion model for novel multi-view synthesis and 3D generation, thereby leveraging the generalization and multi-view consistency of the video models, while further adding explicit camera control for NVS. We also propose improved 3D optimization techniques to use SV3D and its NVS outputs for image-to-3D generation. Extensive experimental results on multiple datasets with 2D and 3D metrics as well as user study demonstrate SV3D's state-of-the-art performance on NVS as well as 3D reconstruction compared to prior works.
