Alter the entries as follows:

Set "network.http.pipelining" to "true"

Set "network.http.proxy.pipelining" to "true"

Set "network.http.pipelining.maxrequests" to some number like 30. This means it will make 30 requests at once.

Set network.http.max-connections: 48

Set network.http.max-connections-per-server: 24

Set network.http.max-persistent-connections-per-proxy: 12

Set network.http.max-persistent-connections-per-server: 6

Set network.http.pipelining: true

Set network.http.proxy.pipelining: true

3. Right-click anywhere and select New-> Integer. Name it "nglayout.initialpaint.delay" and set its value to "0". This value is the amount of time the browser waits before it acts on information it receives.

example:
Target .. "C:\Program Files\Mozilla Firefox\firefox.exe" /prefetch:1

Q n A

So you know about networking?Try answering this question.the answer are here but tyr not to look at it

How does traceroute work? Now how does traceroute make sure that the packet follows the same path that a previous (with ttl - 1) probe packet went in?

See traceroute works using ICMP packets. First source sends an ICMP packet with Time to Live (TTL) field as 1 to the destination address. Now intermediate router receives the packet and sees that TTL field has expired, so it sends a ICMP TTL expired reply. Now the source machine again sends the ICMP packet with TTL field as 2. This time second intermediate router replies. This process is repeated till destination is reached. That way the source can get the entire route up to destination.

How do you do authentication with message digest(MD5)? (Usually MD is used for finding tampering of data)

The unique number will be generated by MD5, if it is tamped with someone, the value will be changed so you know you are tampered

What is ARP and how does it work?

ARP(ADDRESS RESOLUTION PROTOCOL) is a network layer protocol which associates the physical hardware address of a network node(commonly known as a MAC ADDRESS) to its ip address. now an ARP creates a table known as ARP CACHE/TABLE that maps ip addresses to the hardware addresses of nodes on the local network.

if based on the ip address it sees that it has the node's mac address in its ARP TABLE then transmitting to that ip address is done quicker because the destination is known and voila network traffic is reduced.

Name some routing protocols? (RIP,OSPF etc..)

RIP(ROUTING INFORMATION PROTOCOL)
IGRP( INTERIOR GATEWAY ROUTING PROTOCOL)
EIGRP(ENHANCED INTERIOR GATEWAY ROUTING PROTOCOL)
OSPF (OPEN SHORTEST PATH FIRST)
BGP( BORDER GATEWAY PROTOCOL)

What is meant by port blocking within LAN ?

Restricting the users from accessing a set of services within the local area network is called port blocking.

there should be more of these type of questions but i think this is the most common one
