What is the main characteristic of fourth generation?

The main characteristics of fourth generation of computers (1970s-present) Main electronic component – very large-scale integration (VLSI) and microprocessor. VLSI– thousands of transistors on a single microchip. Memory – semiconductor memory (such as RAM, ROM, etc.)

What are the characteristics of fourth generation computer?

Computers of fourth generation used Very Large Scale Integrated (VLSI) circuits. VLSI circuits having about 5000 transistors and other circuit elements with their associated circuits on a single chip made it possible to have microcomputers of fourth generation.

What are examples of fourth generation language?

Fourth Generation Languages :

These are languages that consist of statements that are similar to statements in the human language. These are used mainly in database programming and scripting. Examples of these languages include Perl, Python, Ruby, SQL, MatLab(MatrixLaboratory).

What are the features of fourth generation language give examples of 4GL?

A good example of this type of 4GL language is PowerBuilder. These types of tools can be used for business application development usually consisting in a package allowing for both business data manipulation and reporting, therefore they come with GUI screens and report editors.

What is the 4th generation?

/ˌfɔːθˌdʒenərˈeɪʃən/ us. (also 4G) relating to technology that gives mobile phone and computer users more advanced features: 4G phones/technology/networks. Fourth-generation technology allows networks to handle larger amounts of data at faster speeds.

What are the 5 types of computer generation and their characteristics?

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)

What are the disadvantages of fourth-generation language?

Disadvantages of fourth-generation languages

1. The programs developed in the fourth-generation language are executed at a slower speed by the CPU.

What are the main differences between 4th generation and 5th generation programming languages?

Fifth generation (5GL)

It uses Artificial Intelligence or (AI) technology to solve problems on its own. While fourth-generation programming languages are designed to build specific programs, fifth-generation languages are designed to make the computer solve a given problem without the programmer.

Why fourth-generation language is called non procedural language?

4GLs are usually nonprocedural languages in which the user describes what is wanted in terms of application, not the computer. The processor takes the user’s description and either interprets it directly or generates a program (in a database query language or Cobol) that will perform the desired operation.

What are the 4th generations of computer?

Fourth Generation of computers was between 1971 – 1980. These computers used the VLSI technology or the Very Large Scale Integrated (VLSI) circuits technology. Therefore they were also known as the microprocessors. Intel was the first company to develop a microprocessor.

What are the distinguishing characteristics of fourth and fifth generation of computer?

Computers from fourth generation are in use of everyday work. Fifth generation computers are from the future. Actually the computers from fifth generation are already in use under limited exposure and not available for everyone to try as the development process is still ongoing.

What are the advantages of fourth generation computer?

Advantages of Fourth Generation of Computer

Smaller in size and much more reliable than other generations of computers. The heat generation was negligible. No cooling system is required in many cases of the fourth-generation computer. Portable and cheaper than the older versions.

What is the difference between 4th generation language and 5th generation language?

While fourth-generation programming languages are designed to build specific programs, fifth-generation languages are designed to make the computer solve a given problem without the programmer.

What are the characteristics of first and fourth generation of computer?

  • First Generation Computers (1942 to 1954) – Based on Vacuum Tubes. The first generation computers were used vaccum tubes as the main electronic part. …
  • Third Generation of Computers (1965 to 1974) – Based on Integrated Circuit. …
  • Fourth Generation of Computers (1975– till now )- Based on VLSI Microprocessor.
