Characteristics of second generation computers

There are many Characteristics for a second generation computer.

I haven give all the important Characteristics of second generation computers that I collected through different books, medias etc as different points below.

In the following 8 points you get all the important characteristics of a Second generation computer and if you know some other important characteristics, please let me know it through comment.

Main Characteristics of a second generation computer

The main Characteristics of a second generation computer are

1. Second generation computer machines were based on transistor technology.
2. Second generation computers were smaller as compared to the first generation computers
3. The computational time of  Second generation computers was reduced to microseconds from milliseconds.
4. Second generation computers were more reliable and less prone to hardware failure. Hence, such computers required less frequent maintenance.
5. Second generation computers were more portable and generated less amount of heat.
6. Assembly language was used to program Second generation computers. Hence, programming became more time-efficient and less cumbersome.
7. Second generation computers still require air conditioning.
8. Manual assembly of individual components into a functional unit was still required.
