In these app. The user works at a client PC 3) Clint PC – the user works at a client which receives sercies from another computer called a server . 4) Corporate networking – connect comp. that are inside the same org. support email the WWW, and other organizational app. That u use on the internet. 5) VoIP transmission of telephone calls over networks designed for data. IP is the interent protocol, which carries traffic across the internet. Transmits voice over the internet. 6) Transaction processing app. – are clerical app. Characterized by high volume of traffic. Generate more traffic, payroll, billing, inventory 7) Networking is also used to describe two separate types of traffic a. DATA COMMUNICATION – involves the transmission of data( text, numbers, picture, and other info ) b.
