Depends on what is modifying the controls is using the computers system is operationg.
Is OSPF link state or distance vector or path vector protocol?
OSPF is a link-state routing protocol.
UDP typically should not be used where quality (not speed) is desired.
What are the types of protocols?
routing protocol:
helps to find the best path to transfer the packets from one network to diffrent network
example:
rip: routing information protocol
igrp, ospf......
routed protocol:
helps to carry the packets to the destination.
example:
smtp : transfer the mails
ftp : transfer the files.
What is an optical fiber and how can messages be sent through it?
optical fiber is made from extremely pure glass that is stretched out to a very thin and flexible wire. fiber optic wire is often used in locations of computer networks with a very high load because of the speed of light. it simply uses the same hexidecimal and binary codes to transmit data over the network just like regular Ethernet cables, except much much much faster.
No, ICMP is not a routing protocol. ICMP (Internet Control Message Protocol) is used by the Internet Protocol suite (IP) to send error and status messages. It is mainly used for diagnostics. Ping and traceroute are two tools that use ICMP. ICPM is used by routing protocols, for routing advertisements and router discovery.
Which command can be used on a PC to determine which TCP IP ports are in use?
Open command prompt and type netstat
This will show all ports in use and all ingoing\outgoing connections along with the connection type. TCP, UDP
When would optical fiber be used in ethernet lan?
When you need to cover distances longer than 200 meters. Also fiber optics is recommended when you have high load connection, for instance, between building, floors and so on.
If you don't have a wireless connection, then yes.
dB = 10log10(50Watt)
= 10log10(1000/50)
= 10log10(20)
= 1 + .3010
= 1.3010dB
1.3 - 10 = -8.7dB
What is an autonomous system and what routing protocols operate within an autonomous system?
An autonomous system is a group of networks under the same management domain using an interior gateway protocol such as OSPF.
Internetworking with Cisco and Microsoft Technologies pg. 308
Interior gateway protocols: IGRP, RIP, OSPF, EIGRP
Internetworking with Cisco and Microsoft Technologies pg.295-296
one number of host bits must be left when you doing subnetting.
Pictures of Mechanical Transfer registered Jack?
There are plenty of pictures available via Google - use the 'images' link.
What is an example of a shell extension?
A shell extension allows one to extend the abilities of the shell. For example, in Windows Explorer the program is designed primarily to show you the contents of your system. An extension could be applied to add information (tabs) to a dialog box to show information that was not previously available.
Sw1-sw2 divides the collision domain and provides full media bandwidth to the hosts in the network.
What is the geographical scope of LAN MAN and WAN?
Local area network, Metor area network, Wide area network
What are the disadvantages and advantages to using cat 3 cable for Ethernet?
advantage: it is really cheap.
disadvantage: the top speed is only 10 Mbps
The first part of an IPv4 address identifies the network and the last part identifies the?
host address
How explain different type of Network Address Translation with suitable set of examples?
these are the four types of the topologies such as
WAN:-Wide Area Network
LAN:- Local Area Network
MAN- Metropolitan Area network
CAN:- Campus Area Network
In these topologies meanings are clear for a name
