Ping (cekakan sakaPacketInternetGopher) ya ikuprogram utilitas kang bisa minangka mriksa konèktivitasjaringan kang basisé tèknologiTransmission Control Protocol/Internet Protocol (TCP/IP).[1] Kanthi nganggo utilitas iki, Bisa diuji apa komputer siji terhubung karo komputer liyané.[1] Ping iki dilakokake kanthi ngirimpaket kepadaalamat IP kang arep dijajal konektivitasnya lan ngenteni responne.[1]
Mike Muuss nulis program iki ana ing sasi Dhésèmber 1983, minangka sarana kang gunané ngoleki sumber masalah ana ing jaringan.[2] Miturut Mike Muss uga, jeneng "ping" wiwitane saka swara echo (sonar) ana ingkapal selam yèn nalikane operator ngirimake pulsa-pulsa swara tumuju ing sasaran, mula saka iku swara mau mesti mantul lan ditampa manèh nalika wis ngeneni sasaran lan ana ing jangka wektu dhéwé.[2]
Utilitas ping nuddhuhake kasil kang positif yèn ana komputer loro lan padha-padha nyambung ana ing sawijining jaringan.[2] Kasil awujud statistik kaanan koneksi banjur ditampilake ana ing pérangan keri.[2] Kualitas koneksi disa didelok saka gedhene wektu lunga-bali (roundtrip) lan gedhene jumlan paket kang ilang (packet loss).[2] Sansaya cilik angka kekerone, sansaya apik kualitas koneksine.[2]
