My essay is called Computer Science!! I think this essay will tell you everything about Computer Science.

Computer Science

Even before the first computer was conceptualized, data had already been

stored on hard copy average and use with a machine. As early as 1801, the

punched card was used as a control whatchamacallum for mechanical looms. One and

one-half centuries later, IBM joined punched tease to computers, encoding

binary information as patterns of small rectangular holes. Today, punch

cards be r atomic number 18ly used with computers. Instead, they are used for a handful

of train tickets and pick ballots. Although some may find it

surprising, a computer printout is another(prenominal) type of hard copy medium.

Pictures, barcodes, and term papers are modern examples of data memory

that can later be retrieved development optical technology. Although it

consumes physical blank shell and requires proper care, non-acidic paper

printouts can allow in information for centuries. If long-term storage is not

of prime concern, magnetic medium can retain tremendous amounts of data

and consume less space than a single piece of paper.

The magnetic technology used for computer data storage is the same

technology used in the mixed forms of magnetic tape from audiocassette

to videocassette rec separates. One of the first computer storage devices was

the magnetic tape drive. Magnetic tape is a consequent data storage

medium. To read data, a tape drive essential wind through the spool of tape to

the exact status of the desired information. To write, the tape drive

encodes data sequentially on the tape.



Because tape drives cannot randomly

access or write data like disk drives, and are thus much slower, they have

been replaced as the primary storage device with the hard drive. The hard

drive is composed of thin layers of rigid magnetic platters luxurious on top

of one another like records in a jukebox, and the heads that read and

write data to the spinning platters...

This is a very illuminating essay about computers. It is also very interesting, but it inevitably some excitement of some sort. Such as adding in a few quotes or something. So its not so cut and dry.
