Considering the time period in which this book was written and published, technology is quite advanced. The function of technology in this novel mainly used as a means to monitor the Outer Party members through the use of the telescreens (which are two way so the watchers are being watched). Technology is also used to alter history constantly so that it is not a concrete entity, but rather a fluid one, which is always changing to fit the purposes of the society. Technology is also used to limit the range of human thinking with the use of the Thought Police, who can somehow read the inner thoughts of Party members, and with the creation (or rather destruction) and implementation of Newspeak which also limits the range with which a party member can express oneself. Technology in 1984 is not creature comfort like we know it to be, it was used as a means of keeping society members under control in every way.
