Hello everyone. I am trying to write a quiz for a site. Questions are in multiple choice, true/false, fill in the blank etc. The example questions i have can be seen below.
I'm trying to plan how am I going to code this. I was thinking of having a table with two columns one with questions and one with answers. The part that troubles me is that tutors should be able to upload quizzes in the example format given below. The upload function is not a problem as I already have this implemented this to upload files to registered students pages.
Could anyone give me some suggestions as where to start with this? I just want to know how you guys would approach this task bearing in mind the tutor being able to upload the quizzes in the below format.
Many thanks in advance
`Only digital signals can be used to convey information in the communications environment. False True `The greater the bandwidth of the signal the greater its information carrying capacity. True False `Guided media, also called wireless, provide a physical means for guiding electromagnetic waves through seawater. False True `A major problem in designing a communications facility is transmission impairment. True False `In full-duplex operation both stations may transmit, but only one at a time. False True `A digital signal is one in which the signal intensity maintains a constant level for some period of time and then abruptly changes to another constant level. True False `The frequency is the rate at which the signal repeats. True False `The sine wave is the fundamental aperiodic signal. False True `Analog signals suffer more from attenuation than do digital signals. False True `For any given medium, the greater the bandwidth transmitted, the greater the cost. True False `There is not a direct relationship between data rate and bandwidth. False True `A familiar example of analog data is audio, which, in the form of acoustic sound waves, can be perceived directly by human beings. True False `The advantages of digital signaling are that it is generally cheaper than analog signaling and is less susceptible to noise interference. True False `An analog signal can be transmitted only a limited distance before attenuation, noise, and other impairments endanger the integrity of the data. False True `Delay distortion occurs because the velocity of propagation of a signal through a guided medium varies with frequency. True False `A key parameter that characterizes any electromagnetic signal is ~text~, which is the width of the range of frequencies that comprises the signal. bandwidth analog digital wavelength `In ~text~ transmission signals are transmitted in only one direction; one station is the transmitter and the other is the receiver. simplex half duplex multipoint full duplex `The term ~text~ is used to refer to the transmission path between two devices in which signals propagate directly from transmitter to receiver with no intermediate devices other than amplifiers or repeaters used to increase signal strength. direct link unguided media wireless guided `A guided transmission medium is ~text~ if it provides a direct link between two devices and those are the only two devices sharing the medium. point to point wireless multipoint simplex `A(n) ~text~ signal is a continuously varying electromagnetic wave that may be propagated over a variety of media, depending on spectrum. Examples are wire media and fiber optic cable. analog aperiodic digital periodic `The ~text~ is the maximum value or strength of the signal over time, typically this value is measured in volts. peak amplitude frequency phase period `The ~text~ of a signal is the distance occupied by a single cycle. wavelength amplitude frequency bandwidth `The ~text~ of a signal is the range of frequencies that it contains. spectrum bandwidth effective bandwidth wavelength `A ~text~ signal is a sequence of voltage pulses that may be transmitted over a wire medium. digital text analog audio `The communication of data by the propagation and processing of signals is ~text~. transmission signaling interlacing effective bandwidth `An example of digital data is ~text~ or character strings. text video audio interlaced `_~text~ is generated by terminals, computers, and other data processing equipment and then converted into digital voltage pulses for transmissions. Binary data Text Voice Audio `A reduction in strength is _~text~. attenuation interlacing delay distortion pulsing `The rate in bits per second at which data can be communicated is the ~text~. data rate analog transmission channel capacity digital transmission `When signals at different frequencies share the same transmission medium the result may be ~text~ noise. intermodulation crosstalk white impulse `The designer of a communications facility must deal with four factors: the data rate that is used for digital information, the amount of noise and other impairments, the level of error rate that is acceptable, and the ~text~ of the signal. bandwidth `Twisted pair, coaxial cable and optical fiber are examples of ~text~ media. guided `In a ~text~ guided configuration more than two devices share the same medium. multipoint `The simplest sort of signal is a _~text~ signal, in which the same signal pattern repeats over time. periodic `The ~text~ bandwidth of a signal is the width of the spectrum. absolute `The ~text~ bandwidth is the band where most of the signal energy is concentrated. effective `A technique known as ~text~ is used to provide a flicker free image without increasing the bandwidth requirement. interlacing `A means of transmitting analog signals without regard to their content is ~text~ transmission. analog `To achieve greater distances in digital transmissions ~text~ are used. repeaters `Thermal noise is also referred to as ~text~ noise. white `~text~ noise is noncontinuous, consisting of irregular pulses or noise spikes of short duration and of relatively high amplitude. It is generated from a variety of causes, such as lightning, and faults and flaws in the communications system. Impulse `The maximum rate at which data can be transmitted over a given communication path under given conditions is referred to as the ~text~. channel capacity `The ratio of the power in a signal to the power contained in the noise that is present at a particular point in the transmission is the ~text~ ratio. signal-to-noise `~text~ noise is due to thermal agitation of electrons. It is present in all electronic devices and transmission media and is a function of temperature. Thermal `Because of delay distortion some of the signal components of one bit position will spill over into other bit positions causing ~text~ interference, which is a major limitation to maximum bit rate over a transmission channel. intersymbol
