**[[Orunotu|kọmputa]] njem** bụ kọmputa a na-etinye n'ụgbọala ụfọdụ; ọtụtụ kọmputa njem nke oge a na-edekọ, na-agbakọ, ma na-egosipụta ebe dị anya, nkezi ọsọ, nkezi mmanụ ụgbọala, na ezigbo oge mmanụ ụgbọala.

Kọmputa njem nke mbụ, dị ka Halda Speedpilot, nke onye na-emepụta taximeter na Sweden mepụtara, ka emere na 1950s dị ka ihe eji arụ ọrụ ụgbọ ala iji mee ka onye ọkwọ ụgbọala nwee ike ịnọgide na-enwe oge a nyere, karịsịa nke bara uru na rallying. A rụnyere otu dị ka ngwá ọrụ ọkọlọtọ na 1958 Saab GT750. Fiat 1900 nke 1952 bịara ọkọlọtọ na ngwaọrụ dị mgbagwoju anya, nke a na-akpọ mediometro na Italian, nke gosipụtara nkezi ọsọ. 'afọ 1978, ngalaba Cadillac nke General Motors wepụtara "Cadillac Trip Computer", nke dị na Cadillac Seville; Chrysler weputara kọmputa njem eletrik na Omni / Horizon ya dị ala. Ha nwere ike ịdị site na isi ruo na mgbagwoju anya. Kọmputa njem kachasị mkpa na-agụnye nkezi mmanụ ụgbọala na ikekwe ngosipụta okpomọkụ n'èzí. Ụdị dị n'etiti na-agụnyekarị ozi gbasara mmanụ, ọsọ, anya, isi (compass), na oge agafeela. A na-echekwa kọmputa njem kachasị elu maka ụgbọ ala dị elu ma na-egosipụtakarị ngụkọta nke ndị ọkwọ ụgbọala abụọ, elekere nkwụsị, ozi nrụgide taya, ịdọ aka ná ntị na-agba ọsọ, na ọtụtụ atụmatụ ndị ọzọ.

Mgbe ụfọdụ ihe ngosi kọmpụta nke njem a na-adị na ụyọkọ nlele, dashboard ma ọ bụ ihuenyo sistemụ igodo, ma ọ bụ ihe njikwa n'elu.  Ụfọdụ ihe ngosi gụnyere ozi gbasara mmezi ahaziri.  Acura TL dị ugbu a na-eme nke a na nkebi, buru ụzọ mee ka onye ọkwọ ụgbọ ala mara ozi “N'oge na-adịghị anya”;  ozugbo erutela usoro ihe omume akwadoro, ozi bụ "Emela Ugbu a";  mgbe oge ọzọ ma ọ bụ anya gafere, ozi na-agbanwe gaa "Oge agafee".  Ụgbọ ala Mercedes-Benz na-enyocha mma mmanụ ahụ mgbe niile ma na-ama onye na-anya ụgbọ ala mgbe mmanụ ahụ mebiri emebi ruo n'ókè ụfọdụ.  Ụgbọ ala GM na FCA na-enye ọkwa mgbanwe mmanụ dabere na ọnụ ọgụgụ na ogologo njem, okpomọkụ engine, na ihe ndị ọzọ.  Ụgbọ ala ụfọdụ na-ejikwa kọmpụta njem na-enye ohere ka ndị nwe ya gbanwee akụkụ ụfọdụ nke omume ụgbọ ala, dịka.  otú mkpọchi ike na-arụ ọrụ, ma n'ọtụtụ ụgbọ ala "mkpa ntọala" na-eme ugbu a site na ihuenyo etiti ejiri maka igwefoto ndabere na redio.

Ụfọdụ kọmputa njem nwere ike igosipụta koodu nchọpụta nke igwe na-arụ ọrụ na-eji.  Nke a bara uru karịsịa mgbe onye na-arụ ọrụ na-achọ ịhụ koodu mgbe ọ na-anya ụgbọ ala.  Na 2004, Linear Logic mepụtara ScanGauge, nke n'oge ahụ bụ naanị ngwa ngwa arụnyere (site na OBDII) ngwa nke na-arụ ọrụ dị ka kọmputa njem, 4 n'otu oge dijitalụ gauges, na onye na-agụ koodu nsogbu.  Ngwaọrụ a nwere nha 12 dị iche iche nke enwere ike iji dị ka nlele dijitalụ anọ.  Enwere ike ịhọrọ nkeji nha n'onwe ya n'etiti kilomita/km, galọn/lita, Celsius/Fahrenheit, na PSI/kPa.

In 2008, the OBDuino project announced a low-cost DIY trip computer design using the OBDII interface and the Arduino hobbyist microcontroller platform, released under the GPL open source license.
