Back then they didn't know much about computer technology and didn't have the right technology of which we have today.
The circuits were built up on cards using discrete components, transistors, resitors and capacitors. As technology progressed all these components were incorporated into single silicon chips.
As technology progressed even further, more and more components can be squeezed onto the silicon chips.
As physical limits were met, as to how dense the components could be shrunk down, solutions have been found. Like using lasers instead of normal light, for the photographic mask method of large scale integration.

not small and not also big size computer....
Computers are classified by a number of aspects. By purpose/functionality they are classified into special and general purpose. By size they are classified into mainframes, mini computers, desktops and portables. Historically, the more recent generations of computers were smaller in size and more general-purpose than their predecessors.
Because we were still finding out the info for the computers in around about the middle ot thefirst generation and this had been subsequently led to lack of computer constlier to produce commertial infomation
They can also be classified in different ways like classification of computers by size. v Super computer Super computers can process huge amounts of data, The biggest in size, the most expensive in price than any other is classified and known as super computer. It can process trillions of instructions in seconds. This computer is not used as a PC in a home neither by a student in a college. Governments specially use this type of computer for their different calculations and heavy jobs. Different industries also use this huge computer for designing their products. In most of the Hollywoods movies it is used for animation purposes. This kind of computer is also helpful for forecasting weather reports worldwide. v Mainframes Another giant in computers after the super computer is Mainframe, which can also process millions of instructions per second and is capable of accessing billions of data. This computer is commonly used in big hospitals, air line reservation companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis. This is normally to expensive and out of reach from a salary-based person who wants a computer for his home. This kind of computer can cost thousands of dollars. v Minicomputer This computer is next in line but offers less than mainframe in work and performance. These are the computers which are mostly preferred by the small type of business personals, colleges, etc. v Personal computers Almost all the computer users are familiar with the personal computers. They normally know what the personal computer is and what are its functions. This is the computer mostly preferred by the home users. These computers are lesser in cost than the computers given above and also, small in size; they are also called PCs in short for Personal computers. This computer is small in size and you can easily arrange it to fit in your single bedroom with its all accommodation. Today this is thought to be the most popular computer in all. v Notebook computers Having a small size and low weight the notebook is easy to carry to anywhere. A student can take it with him/her to his/her school in his/her bag with his/her book. This is easy to carry around and preferred by students and business people to meet their assignments and other necessary tasks. The approach of this computer is also the same as the Personal computer. It can store the same amount of data and having a memory of the same size as that of a personal computer. One can say that it is the replacement of personal desktop computer.
it's really big,huge
It was huge! Around the size of an entire room.

Yes. the machines that make them are the size of the first computer. It is huge. it takes a long time to make them. Another thing is that they are colorless.
Sims 3 is a brilliant game, however, is HUGE in size and will probably lag up your computer.
An amount of computer memory, disk space, or document size. 1 Kilobyte is exactly 1024 bytes.
Living things come in many shapes and sizes. An example would be an ant is tiny but an elephant is huge.
huge.
The supported minimum size in 1950 it was the size of a room. They started out like calculators, doing math equations. Now we are more advanced so we can use smaller work spaces.
In computing terms - it's anything that's 'plugged in' to a computer port. That could be anything from a size A0 plotter (a huge printer) to a USB memory stick.
the size of the desktop computer is (small).
