1. What is networking ?
- A computer network, or data network, is a digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections between nodes
2. Where network is used ?
-. * Network is used to sharing hardware resource like (printer,data storage device)
* To share the file and to access the file
* To transfer multimedia message like (Audio, video)
* to access the internet we need network
* Sharing of programs /software
* Sharing of information
* Can access server centered database
3. Token bus
4. FDDI
-Header contains destination MAC address
-Trailer contains source MAC address
-protocol data unit is frame

3. How many types of network are there ?
- 1. LAN ( local area network)
2. Man (metropolitan area network)
3.wan (wide area network)
4. Types of LAN ?
- 1. Ethernet
2. Token ring3. Token bus
4. FDDI
5. Speed of LAN ?
- The speed of LAN can varies from 10 Mbps , 100 Mbps , 1000 Mbps & 10,000 Mbps
6. Speed of MAN ?
- The speed varies from 10Mbps to 100Mbps
7. What is LAN ?
- A local area network (LAN) is a computer network within a small geographical area such as a home, school, computer laboratory, office building or group of buildings. A LAN is composed of inter-connected workstations and personal computers which are each capable of accessing and sharing data and devices
8. What is MAN ?
- A metropolitan area network (MAN) is a computer network that interconnects users with computer resources in a geographic area or region larger than that covered by even a large local area network (LAN) but smaller than the area covered by a wide area network (WAN).
9. What is WAN ?
- covers wide geographical area which include multiple computer or LAN
10. Name 2 different sub types of LAN ?
- 1. PAN (personal area network)
2. CAN ( campus area network)
11. Full from of ITU ?
- INTERNATIONAL TELECOMMUNICATION UNION
12. Full from of OSI ?
- OSI (open system interconnection)
13. What is OSI model ?
- OSI (open system interconnection) is reference model for how applications can communicate over a network . A reference model is a conceptual framework for understanding reletionships. The TCP/IP protocols, which define the internet, do not map cleanly to the OSI model.
14. How many layers are there in ISO model ?
- There are seven layers
15. Name the seven layers of OSI model ?
- 1. Physical layer
2. Data link layer
3. Network layer
4. Transport layer
5. session layer
6. Presentation layer
7. Application layer
16. Working of physical layer ?
- Data will be in bits
- Bits will be converted into light signals or electric signals
- protocol data unit is bits
17. Working of Data link layer ?
- It adds hedder & trailer
-Header & trailer cotains MAC address of source and destination-Header contains destination MAC address
-Trailer contains source MAC address
-protocol data unit is frame
18. Working of network layer ?
-the routing layer
-It provides addressing and routing service
- There are 2 addresses in packet one is source address & another is destination address
-The primary network protocol on the neternet , IPv4 ,IPv6 logical addressing
-It is used to connect multiple network
-network layer does not broadcast the data
-protocol data unit is packet
19. Working of Transport layer ?
-It is responsable to transmite entire message from source to destination by selecting 2 protocol (TCP/UDP)
-protocol data unit is segment
20. Working of session layer ?
1. create & manage the session via port no
2. it works as giving authentication like (user name , password)
3.protocol of data unit is data
3.protocol of data unit is data
21. Working of presentation layer ?
1. create & manage the session via port no
2. it works as giving authentication like (user name , password)
3.protocol of data unit is data
3.protocol of data unit is data
22. Working of presentation layer ?
- 1.used to present the data in correct formate
2. we can assigne security by extention name ( .exe , .com , .in)
3. encoding assigning code
4. encrypting providing security
5. compressed to reduce size of file
6. protocol data unit is data
23. Working of application layer ?
- 1. Appliction of computer runns under application layer
like (yaho, facebook ,messanger)
2. protocol data unit is data
