At this time students not share current papers please i  request to all of you kindly share more papers for others help... in mid term exams students are so very co-operative and share many current subjective questions as well as new MCQs also... but not not...

At this time Hira is the only member here she participate in this discussion... and Sir Tariq Malik shared current questions....

Please pray for me.... Today is my paper at 4:30 pm when i attempt i will share it for all or you.......... 

Thanks to all of You..........

Asslam o ALikm

HF and SHF

High frequency.
HF uses ionospheric propagation. These frequencies move into the ionosphere where the
density difference reflects them back on earth.
It is used for Citizen’s Band Radio, International Broadcasting, Military Communication,
Telephone,
Telegraph and Fax
Super high frequency.
SHF waves are TX using mostly line-of-sight and some Space propagation.
It is used for Terrestrial and Satellite Microwave and Radar Communication devices.

Types of Noise:

Thermal Noise: Due to random originally sent by TX
Induced Noise: Comes from sources like Motors and Appliances

Crosstalk: Effect of one wire on another
Impulse Noise: Spike (A signal with high energy in a very short period of timepower lines,
lightening etc.

ENQ/ACK, POLL/SELECT, why need addressing in second one?  

Addressing is required in Poll / Select method as it is a not point-to-point configuration, For the

primary device in a multipoint topology to be able to identify and communicate with a specific
secondary device, there must be some addressing, while ENQ/ACK method is a point-to-point
method and for point-to-point configuration, there is no need for addressing.

Walaikum Asalam.......

Thank You so much... for sharing the answers... of the current questions..

Be Blessed.... with Blessings of Allah Almighty,.....

Thanks to every one...

My today paper of CS601.........

Total 50 Questions....

40 MCQs......... past papers me se b the... but some are new overall MCQS based on the following topic....

layers of OSI

attenuation

amplified

modems

flexing...etc but all are so simple and easy .....

Subjective questions

which layer is closest to the transmission layer....?

write names of frames which are used during the transmission.

write the propagation which is used to transmit signals from antenna to antenna...

what is meant by NAK???

write the steps of checksum.

physical characteristics of Ethernet...

thin Ethernet topology......

and scenario tha about to enhancer the bandwidth capacity...

 why data rate is high in modems to downloading a file from a internet as compared to upload a file....

baki yad nai...

overall paper easy tha but study k bina kuch b nai so handouts ache se read kr k jaean...

and pray for my result........

Thank YOu and wish you good luck to all.........

 

 Nadia gull  thanks for sharing ur paper..best of luck for ur result 

Attention Students: You don’t need to go any other site for current papers pattern & questions.

HDLC defines 3 types of Frames:
– Information Frames (I-Frames)
– Supervisory Frames (S-Frames)
– Unnumbered Frames(U-Frames)
I-Frames are used to transport user data and control information relating to user data
S-Frames are used only to transport control information
U-Frame are reserved for System Management

–Anytime an error is detected in an exchange, a negative acknowledgement (NAK) is returned and the specified frames are retransmitted.

Physical layer layer is closest to the transmission layer.
