punched card, but they developed that card in 1924 for their electromechanical EAM machines, by modifying a punched card developed in 1890 by Herman hollerith.
Mainframe computers first used star topology

Mainframe computers were developed in the early 1950's when computers were made that size. It means the cabinet more than the contents as early ones had the CPU (Central Processing Unit) in a separate cabinet.
The main limitation the first home computers had was the same as the first mainframe computers had: not enough main memory (RAM) and not enough external storage.
A mainframe is just a physically very large computer, it is programmed no differently than minicomputers and microcomputers. All computers were mainframe computers before the early 1960s (because of the size of vacuum tubes and the first discrete transistors), when discrete transistors and then integrated circuits made possible the smaller minicomputers. In 1971 Intel introduced the microprocessor integrated circuit making the even smaller microcomputers possible.
No, the earliest computers (from the 1940s to the mid 1960s) were all mainframe computers. The first microcomputers were made in the early 1970s. However many of the earliest computers were much slower and had far less memory than the earliest microcomputers!

A minicomputer is a computer of medium power, more than a microcomputer but less than a mainframe. This class of smaller computers were developed in the mid-1960s and a possible candidate for the first early and highly successful minicomputer was Digital Equipment Corporation's (DEC) 12-bit PDP-8 made in the US.

Computers were invented in the early to mid 1940s.
first generation computers were not fast and were less reliable.
Analog computers were first made in the late 1920s, Digital computers were first made in the early 1940s.
