How many wires of cable cat 6 is use for data?
just one optic cable can carry a lot information to computers
What are the 5 companies that are using LAN?
Schools and/or small businesses such as self-employed or restaurants.
What is the role of Network Address Translation of IPv4 address space?
Network Address Translation translates and IP address used in a network to another IP address known within another network. A NAT table is maintained for global to local and local to mapping of IP's. NAT can be statically defined or dynamically translate from a pool of addresses. The NAT router is responsible for translating traffic coming and leaving the network. NAT prevents malicious activity initiated by outside hosts from reaching local hosts by being dependent on a machine on the local network to initiate any connection to hosts on the other side of the router
No - Transport layer protocols are not concerned with addressing packets to the correct system. (True)
Approximately how many ip addresses are available for a single class b ip license?
License? Where do you get this?
In a Class B network there are 2 to the 16th power addresses.
Class B = 255.255.0.0
65536 addresses
In a Class A network there are 2 to the 24th power addresses
Class A = 255.0.0.0
16,777,216 addresses
In a class C network there are 2 to the 8th power addresses
Class C = 255.255.255.0
256 addresses
Class A around 16 million
Class B around 65,000
Class C is actually 254 NOT 256.
IP addresses are leased and therefore the lessee is given a license to use that particular IP address.
What is subnet mask and default gateway?
Subnet mask is a mask used to determine what subnet an IP address belongs to.
Default gateway is the gateway in a network that a computer will use to access another network if a gateway is not specified for use.
The Presentation layer must make certain that the format of the data will be understandable by the Application layer. This includes the use of encryption, compression, different graphics formats, etc.
It uses a technique known as Portable Data Representation that allows data from different hardware to be able to communicate.
Is PC and laptop both are same?
Notebooks and Laptops are the same thing. Both words mean the same computer however a Netbook is where the difference is. A Netbook is usually a computer that has less hardware then the average laptop or notebook. Most Netbooks do not have a CDROM, they are smaller (7-12 inches) and they cost a lot cheaper then the average laptop.
Can you access internet through intranet?
An inhouse Web site that serves the employees of the enterprise. Although intranet pages may link to the Internet, an intranet is not a site accessed by the general public. For more info go to answers.com and type Intranet.
Differentiate between TCP and UDP protocal?
What are the similarities and differences between IUP and IUD?
The differences are that IUP is something helping in professional degrees and everything else. IUD is where everyone is probably into drugs or dating or other things that dont make sense
It depends on the book, but is usually known as the extended network prefix.
fiber
What is the function of the transport layer and which protocol reside there?
Briefly discuss the functions of transport layer.
When saving a file to your school network are you using a wan or lan how do you know?
When saving a file to your schools network, you are using a LAN, because it is a local are network. A WAN uses wide area networks, such as connecting two offices in two different locations.
What are the benefits to using a layered model to describe network protocols and operations?
-Assists in protocol design, because protocols that operate at a specific layer have defined information that they act upon and a defined interface to the layers above and below.
-Fosters competition because products from different vendors can work together.
-Prevents technology or capability changes in one layer from affecting other layers above and below.
-Provides a common language to describe networking functions and capabilities.
How can the subnet mask for a class C address be represented?
255.255.255.0 - in decimal representation
11111111.11111111.11111111.00000000 - binary representation (3 bytes with all the bits equal to 1, the last byte with all the bits equal to 0)
/24 - binary short representation (the number of bits equal to 1)
TCP:
1.reliable transport between
sending and receiving
process
- flow control: sender won’t
overwhelm receiver
- congestion control: throttle
sender when network
overloaded
- does not provide: timing,
minimum throughput
guarantee, security
- connection-oriented: setup
required between client and
server processes
UDP:
- unreliable data transfer
between sending and
receiving process
- does not provide:
reliability, flow control,
congestion control,
timing, throughput
guarantee, security,
or connection setup,
