What is a virus, worm, and Trojan horse? how do computers get them

all • What Is a Virus?

• A program or code that replicates; that is, infects another program, boot sector, partition sector, or document that supports macros, by inserting itself or attaching itself to that medium. Most viruses only replicate, though, many do a large

amount of damage as well • What Is a Worm?

• Write once read many times: an optical disk that enables users to store data but not change it

• What Is a Trojan horse?

• A program that neither replicates nor copies itself, but causes damage or compromises the security of the computer. Typically, an individual emails a Trojan Horse to you-it does not email itself-and it may arrive in the form of a joke program or software of some sort.

1st computer

• Unfortunately this question has no easy answer because of all the different classifications and computers. Therefore this document has been created with a listing of each of the first computers starting with the first programmable computer leading up to the computers of today. Keep in mind that early inventions such as the abacus, calculators, tablet machines, difference machine, etc. are not accounted for in this document.

• The IBM 5100 is the first portable computer, which was released on September 1975. The computer weighed 55 pounds and had a five inch CRT display, tape drive, 1.9MHz PALM processor, and 64KB of RAM.

• The first truly portable computer or laptop is considered to be the Osborne I, which was released on April 1981. The Osborne I was developed by Adam Osborne and weighed 24 pounds, had a 5-inch display, 64 KB of memory, two 5 1/4" floppy drives, and a modem.

• IBM PCD later released the IBM portable in 1984, it's first portable computer that weighed in at 30 pounds.
