Computer History
•
“English mathematician Charles Babbage (1792–1871) designed a
mechanical computing machine called the "analytical engine."
•
“The personal computer (PC), which is also called the microcomputer and
was designed for use by one person, was first developed for businesses in
the early 1970s.”
• “The computer chip, or integrated circuit, was developed in the
late 1950s by two researchers who were working independently
of one another. Jack Kilby (1923– ) developed a chip at Texas
Instruments in 1958, and Robert Noyce (1927–1990) invented a
similar device at Fairchild Semiconductor in 1959.”
•
“The first functional computer program was written by Grace Murray
Hopper (1906–1992), an admiral in the United States Navy.”

Kilobyte or KB - equals 1024 Characters or consisting of a half page of text
Byte (B) - is one Character consisting of 8 binary digits
Nibble - 4 bits or half a Byte
bits (b) - 0's and 1's lowest form of measurement off or on
Gigabyte or GB - equals 1,073,741,824 characters or 1 thousand novels
Megabyte or MB - equals 1,048,576 Characters or one typical novel
Terabyte or TB - equals 1,099,511,627,776 characters or entire library
1,024 Petabytes
A yottabyte is 1024 or
1,000,000,000,000,000,000,000,000 bytes.
• RAM (pronounced ramm) is an acronym for random access memory, a
type of computer memory that can be accessed randomly; that is, any
byte of memory can be accessed without touching the preceding bytes.
RAM is the most common type of memory found in computers and
other devices, such as printers.
Who made the first Laptop
•
The personal computer (PC), which is also called the microcomputer
and was designed for use by one person, was first developed for
businesses in the early 1970s. Digital Equipment Corporation made the
PDP8 for scientific laboratories. Steve Wozniak (1950– ) and Steve Jobs
(1955– ), college dropouts who founded Apple Computer in 1976, are
credited with inventing the first computer for home use. Working out
of a garage, they spent six months developing the prototype (initial
model) for Apple I. It was bought by some 600 hobbyists, who had to
know how to wire, program, and set up the machine. Apple II was
introduced in 1977 as the first fully assembled, programmable
microcomputer. Nevertheless this machine still required customers to
use their televisions as screens and to use audio cassettes for data storage.
The Apple II sold for just under $1,300. That same year Commodore and
Tandy introduced affordable personal computers. In 1984, Apple
Computer introduced the Macintosh (Mac), which became the first
widely used computer with a graphical user interface (GUI). By 1981,
IBM (International Business Machines) had introduced a PC that
quickly over-took the Mac.
Five Major Companies and the
Founders of Them
• Apple : Steve Jobs, Steve Wozniak, and
Ronald Wayne
• Dell: Michael S. Dell
• PC: John Blankenbake
• Hp: Hewlett Packard
• Toshiba: Hisashige Tanaka
Virus, Worm, Trojan Horse
•
Definition: Computer worms are malicious software applications designed to
spread via computer networks. Computer worms are one form of malware along
with viruses and trojans. A person typically installs worms by inadvertently
opening an email attachment or message that contains executable scripts.
•
Through the course of using the Internet and your computer, you may have
come in to contact with computer viruses. Many computer viruses are stopped
before they can start, but there is still an ever growing concern as to what do
computer viruses do and the list of common computer virus symptoms. A
computer virus might corrupt or delete data on your computer, use your email
program to spread itself to other computers, or even erase everything on your
hard disk.
•
A Trojan horse is a destructive program that masquerades as a benign
application.
Unlike viruses, Trojan horses do not replicate themselves but they can be just as
destructive. One of the most insidious types of Trojan horse is a program that
claims to rid your computer of viruses but instead introduces viruses into your
system.
•
Future of Computers
• I think that the computers in the future will be way
more advanced. Like you will be able to talk to the
computer and have it type for you. Have like the
battery life for the computer last a lot long than it
does now. And have a touch screen keyboard.
