KPK 11th Class Computer Chapter 5 Network Communication & Protocols Short Questions Answers
Show all the modes of data communication with the help of a diagram
a. Simplex, half- duplex and full-duplex
b. Synchronous and Asynchronous
a. Simplex, half- duplex and full-duplex Simplex:
Data travels in one Radio and T.V transmissions.
Half-duplex
Data can travel in both direction but not at the same time. The internet browsing is an example of half duplex mode.
Half-Duplex
Full-duplex:
Data can flow in both directions at the same time. The telephone
Communication system is an example of full-duplex communication mode.
Full-Duplex
b. Synchronous and Asynchronous
I. Synchronous Transmission
The is transmitted block by or word by word at the same time.
II. Asynchronous Transmission
The data is transmitted character by character.
Differentiate between Synchronous and Asynchronous transmission.
Synhronous Transmission
Asynchronous Transmission
Data is transmitted at regular time period
Data is transmission irregular time period.
Multiple characters are transmitted at a time
Single character transmission at a time
No error checking is involved
Error checking is involved
Suitable for long-rang transmission
Not suitable for long-range transmission
No use of star and stop bits
Use of star and stop bits
Data transmission speed is faster
Data transmission speed is slower
Differentiate between Guided and Unguided Media.
Guided Media
Unguided Media
Wire is the medium for data transmission
Air is the medium for data transmission
Everyone can’t receive data without wire connection
Everyone can receive data without wire connection
Less expensive way of data transmission
More expensive way of data transmission
Suitable for short-rang data transmission
Suitable for long-range data transmission
Data transmission in the form of current
Data transmission in the form of waves
Examples are Twisted pair cable co-axial cable and Fiber Optic cable
Examples are: Radio Waves, Micro waves, Infrared waves
Differentiate between LAN and WAN?
LAN (Local area Network
WAN (Wide Area Network)
LAN is a computer network covers small area like a home, office or colleges etc.
WAN is a computer network that covers a broad area
Data transfer speed is very fast in LAN (up to 1000 Mbps)
Data transfer speed is slow in WAN (up to 150 Mbps)
LAN is used to share files and hardware like printers
WAN is used to share only data and information i.e email and files
LAN is less costly
WAN is expensive
LAN faces less data v transmission errors
WAN faces more data transmission errors
The best example for a LAN is the network in an organization
The best example for a WAN is the Internet
What is OSI Model?
Layer Function
Application
User interface
Presentation
Data forming
Session
Establish & maint connect
Transport
TCP- Accurate data
Network
IP- Routers
Data Link
MAC-Switches
Physical
Signals- Cables
Compare TCP/IP Model with OSI Model?
TCP/IP Model
OSI MODEL
It has 4 layers
It has 7 layers
It combines presentation and session layer into application layer
It has separate presentation and session layer
It is protocol based model
It is layer based model
It is older model
It is new model
The Network layer in TCP/IP model provides connectionless service
The Network layer of OSI model provides both connectionless service
The transport layer of this model is both connection oriented and connectionless
The Transport layer of OSI model is connection oriented
Differentiate between Circuit Switched and Packet Switched Networks?
Circuit Switched Network
Packet Switched Network
It is connection oriented and may also be connection-less service.
It is commonly connection-less service.
It is costly.
It is less expensive.
Connection is fast and facing no errors.
It faces errors as a result connection is slow.
Best used for transmission of audio signals only.
Best suitable for data. Audio and video signals can also be transmitted in the form of packets.
It has fixed bandwidth allocation.
It has dynamic bandwidth allocation.
Example is Telephone system.
Example is Internet.
Briefly describe IP Addressing.
IP (Internet Protocol) address is a unique number that is used for computer connected to the internet. This address is 32-bit number. The 32 bits are broken into four octets (1 octet is equal to 8 bite) Each octet is represented in decimal and separated by dot. The minimum value for each octet is 0 and maximum value is 255. Each device on a network must have unique IP address to communicate with other network devices. Example of IP address is 192.168.1.1
What are the similarities between TCP/IP and OSI Models?
The main similarities between the two models are:
Both of the models share common application layer.
Both models have comparable transport and network layers.
Both models assume that packets are switched.
All the layers from bottom till Transport Layer provides End to End Transport Service.
All the layers above the Transport Layer are application oriented and use the Transport Service.
How to Write Perfect Short Answers?
In Board Exams, the examiner looks for specific keywords and presentation. Here is how to attempt Chapter 5 questions:
- Ideal Length: Write 3 to 5 lines for each short question. Too short gets fewer marks, too long wastes time.
- Highlighting: Use a Blue Marker to highlight key dates, names, or scientific terms in your answer.
