Answer:
Please check the attachment.
for the assembly language program the jump and move keywords have been used to establish the if else ladder.
Also for the best three marks, we need to store the three theory and two practical marks in an array, and then we can sort it to get the best three marks to find the CA. and then from initial array, we can find the last two practical test parks, and find their average.
Rest of the calculation is as being mentioned in the image. Also, in the image we have 2 practicals. We need to count two instead of three there, and rest is as shown.
Explanation:
The answer does not require any further explanation.
1)The reason as to why scientists opt to transmit data at lower frequency instead of electromagnetic even if it can carry more data at a higher frequencies is because using higher frequencies of electromagnetic spectrum travel shorter distances but have higher data carrying capacity.So this physical characteristic of electromagnetic waves limits the range and availability of frequencies for sending information.
2) Limitations of using electromagnetic waves in sending communication
communication is a process of transmitting and receiving information in the form of signals.high technology communication use electromagnetic waves,there are various types of electromagnetic waves which are used in communication which include radio-waves,microwaves,infrared e.t.c some of their limitations are
i)Because there is limited number of broadcast frequencies the use of transmitters must be restricted in some way or they will seriously interfere with each other.
ii)Through the air signals can be distorted by atmospheric conditions and signals from space are sometimes distorted by solar activity
iii)physical activities such as mountains and buildings can prevent or interfere with some transmissions
iv)Through the air signals are not private,so any tuned receiver within the range can pick up them.
3)Differences between digital and analogue signals
Analogue and digital signal are used to transmit information usually through electric signals.
An analogue signal is continuous wave denoted by sine wave and may varry in signal strength (amplitude) or frequency(time) an example is sound from human voice is analogue because waves are continuous..
A digital signal is a signal in which the original information is converted into a string of bits before being transmitted .example a must for computer processing where is described as using (0s and 1s)and therefore can not take any fractional value.
4)Advantages of using digital signals over analogue signals
one advantage of digital signals are inherently less susceptible than analog signals to interference caused by noise because with digital signal it is not necessary to evaluate precise amplitude,frequency or phase.
Another advantage based in capacity is that digital signals carry more information per second than analogue signals.
Digital signals maintain their quality over long distances better than analogue signals.
5)How we use digital and analogue signals in our everyday live
digital signal processing is the way of life of current generation
example is mobile phones do alot of digital signal processing .they process our our speech digitally to remove background noise,echo e.t.c
Television also do a lot of digital processing of video,audio signal to present them in a better way.
How radio telescopes are used to explore space
A radio telescope is a specialized antenna and radio receiver used to receive radio waves from astronomical radio sources in the sky in radio astronomy.It has several main parts, a dish and antenna,a receiver,a detector and an analyzer.The dish collects the radio signals from space ad focuses them on the antenna.
6)How radio waves are used on earth
Radio waves are used to transmit television and radio programs They have longer wave lengths and are reflected by the ionosphere
7) Reasons why telescopes convert radio waves (analog) to electrical(digital) signals for analysis
This is because signals can be easily stored and transmitted in digital form.The analog is continuous in time and it is necessary to convert this to a flow of digital values.
Answer:
See the components in explaination
Explanation:
In order to make it as IPv6, few key components should be supported, those components are given below:
The infrastructure must support the enhanced protocol StateLess Address Auto-Configuration (SLAAC).
Static addressing with DHCPv6, dynamic addressing with DHCPv6 and SLAAC are the methods used to configure the IPv6. The network administrator should able to understand and implement the IPv6 through the DHCPv6.
Other than the implementation, working of IPv4 and IPv6 are same. Therefore, the administrator need not to learn new information for its working.
As the IPv6 address length is 128-bit and purpose is for everything on line to have an IP address. It must allow the internet to expand faster devices to get internet access quickly.
The DHCPv6 is not supported by all windows. Therefore, network administrator should check the corresponding Operating system (OS) would support the DHCPv6 for IPv6.
The network administrator must have good knowledge and skills on the IPv6.
The above mentioned key components should be verified by the network administrator in order to support for IPv6 project with DHCPv6.
