Computer Networks

In networking and hardware contexts, MAC stands for Media Access Control. Medium Access Control is a common variation, but Media Access Control is the standard terminology.

Routers often have multiple network interfaces (Ethernet, WiFi, fiber, etc.) and each type requires a different link-layer protocol. A single router can implement several link layers simultaneously to support different physical media and connection types.

Reliable delivery is the responsibility of the TRANSPORT layer (TCP), not the network layer. The network layer (IP) provides best-effort delivery without guarantees. Reliability, error correction, and flow control are higher-layer functions.

Traditional telephone networks (PSTN) use circuit switching, where a dedicated communication path is established for the duration of a call. This guarantees quality but wastes resources during silent periods. This contrasts with modern packet-switched VoIP networks.

Datagram networks like IP are connectionless - routers treat each packet independently without maintaining connection state between end systems. Only virtual circuit networks (like ATM) track connections.

ADSL is a point-to-point technology - each subscriber has a dedicated connection to the central office. It is NOT a shared medium like Ethernet or cable modem networks where multiple users share the same bandwidth.

FlexRay operates at the highest speed (up to 10 Mbps) among the listed automotive protocols, designed for high-performance and safety-critical applications like drive-by-wire systems. CAN operates at up to 1 Mbps, MOST at up to 150 Mbps for multimedia, and LIN is the slowest at up to 20 kbps for low-cost body electronics.

MOST stands for Media Oriented Systems Transport. It is a high-speed multimedia network technology optimized for the automotive industry, used to connect infotainment components like radios, amplifiers, and displays.

The RS485 standard specifies a maximum of 32 unit loads on a single network segment without repeaters. While modern transceivers with fractional unit loads can extend this to 128 or more devices, the classic RS485 specification defines 32 as the standard limit. Options A and B (128, 64) require special low-unit-load transceivers, and D (16) is below the standard capacity.

To solve this question, the user needs to know what the WAP protocol is and what it was designed for. The user must then identify which type of clients the protocol was intended to be used on.

The WAP protocol, or Wireless Application Protocol, was designed specifically for wireless clients. It was developed in the late 1990s to enable mobile devices to access internet content over wireless networks.

Therefore, the correct answer is:

The Answer is: B. wireless

WAP (Wireless Application Protocol) was created to enable web access on early mobile devices, primarily phones, not on pagers, desktop computers, or generic networks. It defined how browsers on mobiles retrieve and display content, making mobile phones the intended platform, so the other options are unrelated.

WAP (Wireless Application Protocol) was created to deliver internet content to mobile devices, enabling web‑like experiences on phones. The other choices (network, computer, mobile) do not capture this purpose.

Multicast Transformation in SSIS takes a single input row and distributes it to multiple outputs simultaneously. Each output receives a copy of the same row, enabling parallel processing paths.
