Compare advantages and disadvantages between 3rd and 4th generation of computer.

Third Generation Computers:
Advantages:
• These computers were cheaper as compared to second-generation computers.
• They were fast and reliable.
• Use of IC in the computer provides the small size of the computer.
• IC not only reduce the size of the computer but it also improves the performance of the
computer as compared to previous computers.
• This generation of computers has big storage capacity.
• Instead of punch cards, mouse and keyboard are used for input.
• They used an operating system for better resource management and used the concept of
time-sharing and multiple programming.
• These computers reduce the computational time from microseconds to nanoseconds.
Disadvantages:
• IC chips are difficult to maintain.
• The highly sophisticated technology required for the manufacturing of IC chips.
• Air conditioning is required.
Fourth Generation Computers:
Advantages:
• Fastest in computation and size get reduced as compared to the previous generation of
computer.
• Heat generated is negligible.
• Small in size as compared to previous generation computers.
• Less maintenance is required.
• All types of high-level language can be used in this type of computers.
Disadvantages:
• The Microprocessor design and fabrication are very complex.
• Air conditioning is required in many cases due to the presence of ICs.
• Advance technology is required to make the ICs
