What is BSCD Full Form?

BSCD full form is Bachelor of Science in Community Development.

What is Bachelor of Science in Community Development?

The Bachelor of Science in Community Development prepares students to learn to understand and think critically about the social, political, economic, and cultural dynamics shaping various types of communities.

Particular emphasis is given to empowering disadvantaged communities to address inequalities and improve their long-term social, economic, and environmental sustainability.

The program enables students to lead efforts to create and maintain healthy, sustainable communities by providing a broad-based understanding and awareness of multi-dimensional aspects of urban and suburban community challenges in a metropolitan regional context and the means of effecting change from both grass-roots and public policy perspectives.

What is CDMA Full Form?

CDMA full form is Code Division Multiple Access.

What is Code Division Multiple Access?

Code-division multiple access (CDMA) is a channel access method used by various radio communication technologies. CDMA is an example of multiple access, where several transmitters can send information simultaneously over a single communication channel. This allows several users to share a band of frequencies (see bandwidth). To permit this without undue interference between the users, CDMA employs spread spectrum technology and a special coding scheme (where each transmitter is assigned a code).[1][2]

CDMA optimizes the use of available bandwidth as it transmits over the entire frequency range and does not limit the user's frequency range.

It is used as the access method in many mobile phone standards. IS-95, also called "cdmaOne", and its 3G evolution CDMA2000, are often simply referred to as "CDMA", but UMTS, the 3G standard used by GSM carriers, also uses "wideband CDMA", or W-CDMA, as well as TD-CDMA and TD-SCDMA, as its radio technologies.

It can be also used as a channel or medium access technology, like ALOHA for example or as a permanent pilot/signalling channel to allow users to synchronize their local oscillators to a common system frequency, thereby also estimating the channel parameters permanently.

In these schemes, the message is modulated on a longer spreading sequence, consisting of several chips (0es and 1es). Due to their very advantegous auto- and crosscorrelation characteristics, these spreading sequences are also used for radar applications since many decades, where they are called Barker-Codes (with a very short sequence length of typically 8 to 32).

For space based communication applications, it is also used since many decades, due to the large pathloss and Doppler-shift caused by the satellite motion. Typically in those applications, neither FDMA nor TDMA is used as a single modulation, due to this effect. CDMA is often used with BPSK in its simplest form, but can be combined with any modulation scheme like in advanced cases QAM or OFDM, which typically makes it very robust and efficient (and equipping them with accurate ranging capabilities, which is difficult without CDMA). Other schemes use subcarriers based on binary offset carrier (BOC), which is inspired by Manchester codes and enable a larger gap between the virtual center frequency and the subcarriers, which is not the case for OFDM subcarriers.

Code Division Multiple Access (CDMA) is a sort of multiplexing that facilitates various signals to occupy a single transmission channel. It optimizes the use of available bandwidth. The technology is commonly used in ultra-high-frequency (UHF) cellular telephone systems, bands ranging between the 800-MHz and 1.9-GHz.

What is CDR Full Form?

CDR full form is Controlled Directional Reception.

What is DCD Full Form?

DCD full form is Data Carrier Detect.

What is Data Carrier Detect?

Data Carrier Detect, abbreviated as DCD, or alternately Carrier Detect abbreviated as CD, is a control signal present inside an RS-232 serial communications cable that goes between a computer and another device, such as a modem. This signal is a simple "high/low" status bit that is sent "from DCE to DTE", or in a typical scenario, from the peripheral to the computer. It is present on virtually all PC serial ports - pin 1 of a nine-pin (DE9) serial port, or pin 8 over a 25-pin (DB25) port. Its purpose varies depending on the device connected, but the most typical meaning is to indicate when a modem is connected to another remote modem via telephone lines.

The word "carrier" is a reference to the analog carrier signal generated by a modem, which is modulated to carry the data. On a data modem, loss of the carrier equates to termination of the connection.

Much like the Ring Indicator signal, on a PC's serial port, changes to the DCD signal state can generate a hardware interrupt that can be captured by the processor any time the DCD signal changes state, preventing the PC from needing to constantly poll the pin.
