Is it true that wrapping up of data of different types into a single unit is known as encapsulation?
Not quite. Encapsulation means to combine data and the methods that work upon that data into a single unit (an object), such that access to both the data and methods is restricted in a controlled manner. Data-hiding is fundamental to encapsulation.
If two switches each support all types of trunk encapsulation on a link between them which type of encapsulation will be negotiated?
12
What is the name of the process of building a frame around network layer information?
Encapsulation. Actually, this is one type of encapsulation; encapsulation occurs at several layers.Encapsulation.

What is different between inheritance and encapsulation?
wrapping up of data and function into a single unit is called encapsulation where polymorphism is the ability to take more than one form
How many different types of network are there what makes them different?
There are many different types of networks which include Local Area Networking (LAN), Wide Area Networking (WAN) and Metropolitan Area Networks (MAN) among others. The area of coverage is what mainly makes then different.
What are the various topology of WAN and what is the drawback in BUS topology?
there are a few different topologies when you are talking about WAN's but remember WAN's topologies are different than LAN's because of the area they cover. But there are bus wan, ring wan, star wan, full mesh wan, partial mesh wan, and tiered wan. as far as a drawback to bus topology is that each site in the wan bus topolgy depends on every other site in the network to transmit and receive its traffic.
What are different properties provided by Object-oriented systems?
Polymorphism,Inheritence,Abstraction and Encapsulation
Briefly explain why the serial interfaces of the router do not have MAC addresses?
Serial interfaces do not pass any MAC information because the information is formed using WAN encapsulation (PPP. HDLC, Frame Relay).
Which layers of the OSI model does a WAN operate?
According to Cisco Curriculum Semester 4 1.2.1.1 As described in relation to the OSI reference model, WAN operations focus primarily on Layer 1 and Layer 2. WAN access standards typically describe both Physical layer delivery methods and Data Link layer requirements, including physical addressing, flow control, and encapsulation.
What are the 4 types of area network?
LAN,WAN,MAN,PAN
Is DSL a WAN data link encapsulation?
Frame relay and PPP is used with WAN encapsulation. Frame Relay most closely compares to the OSI data link layer (Layer 2). If you remember that the word "frame" describes the data link layer protocol data unit (PDU), it will be easy to remember that Frame Relay relates to OSI Layer 2. Like other data-link protocols, Frame Relay can be used to deliver packets (Layer 3 PDUs) between routers.
What transforms a LAN to a WAN?
LAN (Local Area Network) is different to a WAN (Wide Area Network) in that a WAN is a network that joins two different LANs. e.g. You may have two office, one in London and one in Manchester. They will have their own LANs. If they link their networks together it will become a WAN.
