What are the disadvantages of second generation computers?

Answer 1

First generation computers could not use semiconductors for processing logic or for data storage (memory) so theyused much more electric power and were very unreliable compared to modern semiconductor logic and RAM memory systems.

A longer answer

As they could not use semiconductors - because they had not been invented - first generation computers had to use expensive magnetic core arrays for memory and telephone exchange switching technology called relays and thermionic tubes (or "valves" in British parlance) for logic processing.

Compared to semiconductor-based systems, those kinds of computing equipment were very bulky and expensive to make. They were also very unreliable so that, before they could be used each day, they required a lot of downtime for repairs and testing.

A comment

Some advantages of the old computers were that they displayed information in black and white (not color) and had no access to the internet to find information because the Internet did not exist!
they were too slow to work.

they did not have proper mechanism.

they even didn't show all the properties in it.

they were unable to understand analytical language.

Answer 2

Advantages of computer:

Fastest calculating device of their time.

Vacuum tube were the electronic components available during those days.

Disadvantages of computer:

Unreliable

Too bulky

Air conditioned (AC) required.

Answer 3

The first electronic computers were built during the second world war to decrypt German coded signals.

The advantages of the earliest computers is that they could perform thousands of calculations each second, making it possible decode messages in a useful time period (a few hours).

This was, pretty much, the only real advantage - the "father" of these computers (Alan Turing) had originally planned these machines to try and prove mathematical conjectures, but this type of application couldn't be considered until after the war.

The disadvantages were many: they were very expensive, they contained thousands of valves (vacuum tubes) making them unreliable - although nowhere near as bad as feared, they had to be programmed in machine code.

The major limitations for early computers was that memory was practically non-existant; only punched tape, delay line memory and Mercury memory were available.

Answer 4

1.Air-conditioning required.

2.Frequent maintenance required.

3.Manual assembly of individual components into a functioning unit was required.

4.Commercial production was difficult and costly.

Answer 5

Actually I asked this question so I don't know the answer
