Electronic Delay Storage Automatic Calculator (EDSAC) - 1949

Electronic Discrete Variable Automatic Computer (EDVAC)

Answer 3

A computer is a machine that manipulates data according to a set of instructions.

Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940-1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into a wristwatch, and can be powered by a watch battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". The embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are however the most numerous.

The ability to store and execute lists of instructions called programs makes computers extremely versatile, distinguishing them from calculators. The Church-Turing thesis is a mathematical statement of this versatility: any computer with a certain minimum capability is, in principle, capable of performing the same tasks that any other computer can perform. Therefore computers ranging from a netbook to a supercomputer are all able to perform the same computational tasks, given enough time and storage capacity.

Answer 4

The first computers used memorycards in order to store minute amounts of data for internal calculations. The computers at early beginning was less complex than the smallest calculator of today, and due to large components often filled large rooms and used a lot of electricity.

The first non electronical way of actually storing data so that it could be read back again was strips of thick paper with binary sequenses of holes in them. So called PunchCardStrips.

Later the use of magnetic tapes moved in, but was critisized due to wear and tear and data not being readily available as one often had to wind the tapes an awful lot back and forth in order to get the data one wanted.

Even in the Mid 80s this method was popular, just look at the Commodore 64, Sharp and Sinclair computers (among others)

IBM employees developed the first actual Harddisk at the size of a fridge.

It was developed in 1956 and was named RAMAC (or Random Access Method of Accounting and Control) . It could store 2000 bits per square inch. Today we can store a lot more in less than a square millimeter.
