Facts: -The computers itself in 1941 was huge, blow, and pretty unreliable. -Vacuum tube: Were used as the internal computer components in regulation and climate control. This caused it to burn out frequently. -Can calculate 1000 Addition per second. -Size: Size was equivalent to the average room (10 by 12 to 12 by 14) -Language: Machine and Assembly language. -Main Component: Vacuum Tubes -Input/Output Media: Punch cards & paper tape. -Storage Media: Magnetic drum & Magnetic tape. Advantages: -It was the only electronic device. -First device to hold memory. Disadvantages: -Too Bulky I.e. large in size. -Vacuum tubes burn frequently. -They were producing heat. -Maintenance problems.
Second Generation Computers
Second Generation Computers (1956-1963) (Sub-Topic 1)
Famous Scientist During This Era: John Bardeer, Walter Houser Brattain, and William Shockley. Pros: Need no time to warm up. Transistors were a great deal smaller than vacuum tubes. It consumed less energy. Generated less hear, therefore making it less of a fire hazard. Was faster and more reliable. Facts: -Size: Smaller than 1st generation -Language: Assembly & high level language. -Main Component: Transistors -Input/Output Media: Punch cards & printed -Storage: Magnetic tape & magnetic disk. Advantages: -Size reduced considerably. -They were very fast. -They were reliable. Disadvantage: -They over heart quickly. -Maintenance problems.
Third Generation Computer
Third Generation Computers (1964-1971) (Sub-Topic 2)
The IBM 370 were the computers in use at this time, and were sold in different modles and sizes. It was mostly used for business and scientific programs. The other models introduced were the CDC 7600 and B2500. Silicone chips were made in 1961 at the Silicone Valley. It then became the integrated circuit technology which had been decreased in size and cost of computers. Magnetic Core Memory was traded out by a device called the microchip.
Facts: -Size: Disk size mini computers -Language: High level language -Main Component: ICs (Integrated Circuits) -Input/Output Media: Key to tape, key to disk & printed reports -Storage Media: Magnetic tape & magnetic disk Advantages: -ICs are very small in size -Improved performance - Production cost cheap Disadvantages: -ICs are sophisticated
It took only fifty-five years for four generations to evolve. The growth of the computer industry have developed technologies of computer inventions. They have been able to invent many types of computers that include tables, convertibles, desktops, laptops, and cellphones. There are many types of computer models such as: -Apple Macintosh -IBM -Dell -Acer Facts: -Size Typewriter size micro computer -Language: High Level Language -Main Components: ICs with LSI (large scale iteration) -Input/Output Media: Keyboard data entry, input devices & printed reports -Storage Media: Magnetic Disk, floppy & optical disk Advantages: -It is a compacts -Less power consumption -Production cost is cheap Disadvantages: -Not artificial intelligent.
Fifth Generation Computer
Fifth Generation Computers (Present Day & Beyond) (Sub-Topic 4)
Technologies are still becoming more advanced and still being developed so that they are much more efficient. For example a few programs today are bale to translate to different languages and do voice command. Today we use various types of computers like smartphones, laptops, tablets, notebook, etc.. It is amazing to know and see that we use computers everyday from a small calculator to a highly build machine. Features of Fifth Generation Computers: 1. Fifth Generation desktop PCs and workstations are several times more powerful that fourth generation. 2. Portable PCs are much smaller and handy than PCs of fourth generation allowing users to use computing facilities even while travelling. 3. They consume less power than their predecessors do. - The fifth generation computers are such as: Silicon chips Processor Robotics Virtual reality Intelligent systems
Facts: -Size: Credit card size micro computers. -Language: Artificial intelligence language -Main Component: SLSI/USI (Super/Ultra Large Scale Integration) Input/Output Media: Tactile inputs, displays -Storage Media: Optical disk & card magnetic disk Advantages: -Artificial Intelligence -Expert system -Very low cost Disadvantages: -None
