vocabulary: comparison hithiker and hijacker

Question

I always confuse hithiker and hijacker.Could someone help me to explain the meaning the source of these two words in order to use correctly.

Mister Micawber · Accepted Answer

It is interesting that they both appeared at about the same time: during the Roaring Twenties--

http://www.etymonline.com/index.php?term=hijack

1923, Amer.Eng., from high(way) + jacker "one who holds up." Originally "to rob (a bootlegger, smuggler, etc.) in transit;" sense of "seizing an aircraft in flight" is 1968 (also in 1961 variant skyjack), extended 1970s to any form of public transportation.

http://www.etymonline.com/index.php?term=hitch

c.1440, probably from M.E. icchen "to move as with a jerk, to stir" (c.1200). It lacks cognates in other languages. Sense of "become fastened by a hook" first recorded 1578, originally nautical; the connection with icchen may be in notion of "hitching up" pants or boots with a jerking motion. The noun sense of "obstruction" is first recorded 1748. Military sense of "enlistment" is from 1835; verb meaning "to marry" is from 1844. Hitchhike is first attested 1923, from the notion of hitching a sled to a moving vehicle (a sense first recorded 1880) + hike.

I think you mean hitchhiker and hijacker.

A hitchhiker is someone who needs a ride to somewhere and stands by a road hoping a motorist will stop and take them. It is entirely voluntary on the part of the driver, who will take them as far as convenient and then drop them off, probably to wait for another ride. Hitchhikers commonly stand at the roadside with a sign with their destination. Most people don't pick up hitchhikers and it can take a long time to get where you want to go! Hitchhiking only refers to cars/lorries etc. Hitchhiking is legal. the driver is helping him out by choice.

A hijacker takes over a form of transport by force - whether a car or an aeroplane - by the threat or even use of violence and weapons. Hijacking is illegal.

Mister Micawber · Answer

There is this definition, Ninh Phuong, if you can understand it (I cannot!)--

(n.) Also referred to as TCP session hijacking, a security attack on a user session over a protected network. The most common method of session hijacking is called IP spoofing, when an attacker uses source-routed IP packets to insert commands into an active communication between two nodes on a network and disguising itself as one of the authenticated users. This type of attack is possible because authentication typically is only done at the start of a TCP session. Another type of session hijacking is known as a man-in-the-middle attack, where the attacker, using a sniffer, can observe the communication between devices and collect the data that is transmitted.

Also, on forum-type websites such as this, to hijack a thread means to change the topic of a thread to suit one's own purposes.

Why can't understand it? Do you know what TCP/IP protocols are?

Dear Yohf

I think Mr Micawber is a kind man. He wants to help me to distinguish these two words.As the matter of fact it's me ,I don't understand anything about them because I can't change my name in order to make thing simpler.So, could you tell me a simple example in every type of Hijacker.And an another word,I've just heard the word hacker.It makes me worried.I will confuse it with hijacker more than hitchhiker.Is there a relationship between hacker and hijacker?

Pieanne · Answer

"Hi - jacker" and "Hitch - hiker" have already been explained (the roots/origins are different). Now, a hacker is "a programmer for whom computing is its own reward; may enjoy the challenge of breaking into other computers" (Hyperdictionary). So, a "hacker" is someone very good at programming; it is mostly associated with breaking into securized firms, such as banks, FBI, etc... A "hacker" is some kind of felon.
