   • Fourth Generation of Computers

     By the time of the discovery of the computer through Charles Babbage, technology had advanced and superior in a completely vast manner. This development in technology and consequently the improvement of computer systems are grouped in numerous generations. Each generation of computer systems has a few vast alternates of their function and far greater benefit than the preceding generation of computer systems. So, it is often stated that a generation is regularly referred to as an alternate and development in the era. Basically, there are 5 generations of computer systems indexed under and they vary from each other in terms of architecture, occupying space, language, specification, function or operation performed, etc. Following is the list of computer generations:

     1. First Generation of Computers(1940 – 1956): The duration from 1940-1956 changed into the duration of first-generation computer systems. They are essentially primarily based totally on vacuum tubes, and vacuum tubes are used because of the simple components for memory and circuitry for the CPU (Central Processing Unit). For example, UNIVAC-1 and ENIVAC.

     2. Second Generation of Computers (1957 – 1963): This generation includes styles of gadgets transistors and...

     • Very Large Scale Integrated (VLSI) circuits are used in a microprocessor-based system.
     • In this generation, microcomputers became the most affordable.
     • Handheld computers have grown in popularity and cost.
     • In this age, networking between systems was invented and became commonplace.
     • The quantity of memory and other storage devices available has expanded dramatically.
     • The outputs are now more consistent and precise.
     • The processing power, or speed, has skyrocketed.
     • With the expansion of storage systems’ capacity, huge programs began to be used.
     • Great advancements in hardware aided in the improvement of the screen, paper, and other output.
     • Multiple high-level languages, such as BASIC, PASCAL, COBOL, FORTRAN, and C, were developed in the fourth generation.
     • They were designed to be used for a wide range of purposes (general-purpose computers).
     • Smaller and more dependable than previous generations of computers.
     • There was very little heat generated.
     • In many circumstances, the fourth-generation computer does not require a cooling system.
     • Portable and less expensive than previous versions.
     • Computers from the fourth generation were significantly quicker than those from previous generations.
     • The Graphics User Interface (GUI) technology was used to provide users with better comfort. During this time, PCs became more inexpensive and widespread.
     • Repair time and maintenance costs are reduced.
     • They were also created with the intention of being used in commercial production.
     • In this form of computer, any type of high-level language can be employed.
     • The fabrication of the ICs necessitated the use of cutting-edge technologies (Integrated Circuits).
     • Only ICs can be made with a high-quality and reliable system or technology.
     • Microprocessors must be manufactured using cutting-edge technology, which necessitates the use of a cooler (fan).

   • what is the benefit of the Fourth normal form?

     Top Answer

     Answered Aug 19, 2015 · 3 votes

     The benefit of conforming to BCNF or 4NF is very similar to the benefit of conforming to 2NF or 3NF. It eliminates some harmful redundancy, and thereby prevents certain cases where the database contradicts itself.

     It's a rare case where a table can be in 3NF but fail to be in BCNF or 4NF. But they do occur, and they are documented in full descriptions of the normal forms.

     For example, see this description: https://en.wikipedia.org/wiki/Boyce%E2%80%93Codd_normal_form This description shows a table that is in 3NF but not BCNF.

     How much effort you should expend in making sure a design conforms to BCNF or 4NF depends on the nature of your project. There are many design situations where checking for conformance to 3NF is good enough.

   • What was the quantity of the most expensive item ordered using Pandas

     Top Answer

     Answered Jan 01, 2020 · 1 votes

     Without using sort we can get the max of item_price and then get the quantity with Series.shape:

     df[df['item_price'] == df['item_price'].max()].shape[0]-#Out3

     Or if you used sort, we can get the first group with GroupBy and check the size:

     grps = [grp for _, grp in df.groupby('item_name', sort=False)]print(grps[0].shape[0])-#Out3

     Not very general, but if you want to get a certain group after groupby, use GroupBy.get_group by index name:

     df.groupby('item_name').get_group('Steak Salad Bowl').shape[0]-#Out3

   • What was the role of Mahatma Gandhi in the Champaran Movement?

     Champaran was a district in the Indian state of Bihar, which is now divided into two districts: East Champaran and West Champaran. The first Satyagraha movement inspired by Mahatma Gandhi occurred in Champaran in 1917. The Champaran Satyagraha was the first to begin, but the term Satyagraha was originally used in the anti-Rowlatt Act movement.

     Indigo plantation in Champaran

     It was a permanent settlement region made up of big zamindari estates ruled by wealthy and powerful landlords. Most of the villages were leased by zamindars to thikadars, the most powerful of whom were European Indigo Planters. Even though the planters only had a temporary lease, they were able to collect rent from the peasants as well as exercise civil and criminal jurisdiction. Champaran has been growing indigo since the late 18th century. However, the first indigo industry was established in...
