Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

Internt has its roots in a network that became functional in 1969?
The Advanced Research Projects Agency network, ARPANET (later DARPANET).
The only way that could work is if the DHCP service and the HTTP service were configured and running on the same physical machine. Otherwise they could not use the same IP address.
DHCP and HTTP do not have to be on separate machines (but it is a good idea to separate them in a network).
A better question might be why the two services *require* the same IP address.
What is the purpose of twisting wires closely together as in twisted-pair cable?
To minimize crosstalk
Which is more secure an LM hash or an NTLM hash?
NTLM Hash is more secure than LM Hash. It was actually replaced by Windows with NTLM. NTLM is case sensitive; so it matters how passwords are typed, its character set is 65,535, and it does not limit stored passwords to two 7- character parts. NTLM is considered a much stronger hashing algorithm. Just make sure passwords stored are more than 14 characters and you will be fine. Now Unix and Linux are probably a more stable OS because they use "salt" Windows LM and NTLM does not.
How do you plan to achieve these goal?
am bringing my personal and professional experiences, my knowledge, skills and abilities to this new position. I plan to work diligently to master the duties and tasks of the position and the performance objectives established by my new supervisor and myself as well as embrace every opportunity to grow with the company.
Tell about your long term goal,eg:CXO or baord of directors and then draw the path way in reverse order,i.e for CXO you have to be VP,Director,Delivery Head,Program manager,Senior Project Manager,Project Manager...seeing that you now aspire to be a consultant or BA or team lead..five years down the lane you aspire to reach the role of senior project manager,by ur hardwork and by building and leveraging on strong networks which you have build all through these years you hence plan to acheive those goals
Are wireless routers directional?
AFAIK routers are omni-directional. Though these days its not uncommon to buy routers with detachable ariels. So it wouldn't be a big deal to hook up a cantenna.
Does more Static IP addresses speed up the internet connection?
No. Neither the type nor number of IP addresses in use have any effect on the speed of the connection. In a practical sense however, having more IP addresses generally means there are more computers sharing the connection and thus decreases the available bandwidth to each computer. Conversely, lines with static IPs generally have higher bandwidth because they're generally for business use and are more expensive. This is not a result of the IP addresses, it's just that the two normally go hand in hand.
What type of routing protocol is OSPF?
OSPF is short form of open shortest path first. OSPF is based on linked state routing.
The Physical address can be calculated as
Physical address = Base address + Offset.
So take Base,Offsets,Lengths in to different arrays and check whether offset is less than length , if it is then the physical address would be base+ Offset , if not then that is a segment error.
What are the advantages to using cable clips?
Cable clips make sure that your cables don't get in the way. You can attach cable clips to your cables to secure them to your walls. That way you can easily conceal them.
well it depends on what sort of network r u connected and how much secure u r YOURSELF .
Depends on what your doing, most common use today is for POE (power over ethernet)
In I.T.:
A hand shake is a term used when creating a virtual connection between hosts.
An example of this is with the TCP protocol's 3-way handshake in which a connection must be established for communication...
1. The client sends a SYN (Sync) packet to the remote host when it needs to negotiate a connection, which includes an initial sequence number. This indicates to the other computer that the client wants to negotiate a connection.
2. When the remote host receives the packet, it records the sequence number and replies with an acknowledgement (ACK), which is the initial sequence number which the client sent +1 (a way of verifying receipt by saying, 'i received your sequence number and i am expecting the same number +1 next'). It also sends its own sequence number so the client can do the same in the next step...
3. The client receives the remote hosts own sequence number +1 in the ACK packet which confirms it is communicating with the desired computer and responds with its own ACK of the remote hosts sequence number +1. This confirms the connection and the hosts can now begin communication.
Every packet sent afterwards carries on using sequencing numbers so each end knows where the data came from and in what order it is to be assembled.
- cables are ethernet cables that you can use to create a network between two computers?
Crossover cables are used to connect like-hardware devices or to connect anything other than a hub or switch to a computer. The crossover cable connects the four pins that are used to communicate traffic over the cable together between the two devices.
Most network adapters manufactured recently can automatically sense a straight-through cable and auto-switch accordingly. All gigabit NICs are capable of this.
What is the full expression of the abbreviation HUB switch?
Hub is not an abbreviation. A hub is the center of a wheel; that's where the name of the networking hub is derived from.
