Connect:Direct. Connect:Direct —originally named Network Data Mover (NDM) —is a computer software product that transfers files between mainframe computers and/or midrange computers. It was developed for mainframes, with other platforms being added as the product grew. NDM was renamed to Connect:Direct in 1993, following the acquisition of ...
Hop limit. Known as time to live (TTL) in IPv4, and hop limit in IPv6, this field specifies a limit on the number of hops a packet is allowed before being discarded. Routers modify IP packets as they are forwarded, decrementing the respective TTL or hop limit fields. Routers do not forward packets with a resultant field of 0 or less.
List of interface bit rates. This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger ...
Maximum transmission unit. In computer networking, the maximum transmission unit ( MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. [1] The MTU relates to, but is not identical to the maximum frame size that can be transported on the data link layer, e.g., Ethernet frame .
The Internet Protocol ( IP) is the network layer communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet . IP has the task of delivering packets from the source host to the destination host solely based on the ...
Dial-up Internet access is a form of Internet access that uses the facilities of the public switched telephone network (PSTN) to establish a connection to an Internet service provider (ISP) by dialing a telephone number on a conventional telephone line. Dial-up connections use modems to decode audio signals into data to send to a router or ...
The IPS/UPS is a wide area synchronous transmission grid of some CIS countries, with a common mode of operation and centralized supervisory control. It has an installed generation capacity of 300 gigawatts, and produces 1,200 terawatt -hours (TWh) per year for its 280 million customers. The system spans eight time zones.
Time to live ( TTL) or hop limit is a mechanism which limits the lifespan or lifetime of data in a computer or network. TTL may be implemented as a counter or timestamp attached to or embedded in the data. Once the prescribed event count or timespan has elapsed, data is discarded or revalidated. In computer networking, TTL prevents a data ...
