As the computer industry was introduced in the nineteenth century and it was flourishing and growing all over the globe. So, this was the time when the whole world wanted a computer that should be manufactured in such a way that it should be used specifically for the research purposes in the computer sciences field. During the second era of computers in a technology teaching university for the first time IBM 1620 was introduced and used. This system was based on the transistors and its complete circuitry was transistorized.
The speed of this model was also quite impressive at that time as it is believed that these systems had the internal processing speed of round about twenty microseconds. Along with this speed these IBM 1620 systems also had better data saving capability which was round about twenty thousand in digits.
Input and Output of IBM 1620
In the IBM 1620 computers the Programs and coding languages were feed to the system using the keyboard, paper and by using the punch cards, however the IBM 1620 model had no card reader installed in it. The output of this system was simple gained through the paper and sometimes the printing machines were also to be used. In contrast to the fixed word length in binary, it utilized a variable word length decimal.
Features of IBM 1620
This system was a great invention and that’s why it reached all around the world very easily. The IBM 1620 was such a data processing system that it could be used for the generic as well as for program storage purposes by small enterprises, research that is carried out at a larger scale. The IBM 1620 systemwas useful for all of these including the school level students looking for their solutions and universities where engineering and management students were seeking solutions of difficult engineering, research and management challenges.
In addition to cost reduction, the streamlined design led to a rather sluggish computer. The IBM 1620 might potentially increase the number of thousand pairs per second at full speed – over one thousand times quicker than using a mechanical calculator, and hence it was so beneficial for the IBM 1620.
Operating System of IBM 1620
Every computer model that is introduced in a specific generation of computer has its own specified and defined operating system on which its users and operators use it to get their required task done. In the same way the IBM 1620 system also have their specified and defined operating system for the computer was the operator who would load programs from accessible mass storage media like punched card decks or paper rolls in the adjacent cabinets using the computer console controllers consisting of a front panel and typewriter. Later in many other model the disk storage device on your computer reduced the number of cards or paper rolls to acquire and carry and could install a rudimentary ‘Monitor’ operating system to assist pick what to load from your drive.
