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.

What are advantages of computer aided project management?
Allows one project manager to manage multiple projects due to assisting in automatically collecting status update from the team rather than doing it manually.
What is a stale dhcp certificate?
DHCP is used to assign IP addresses to computers joining a network. Many ISPs use DHCP to give their customers IP addresses. When DHCP assigns you an IP address, or sends you a "DHCP certificate," it "leases" the IP address to you for a period of time. When this lease runs out, the DHCP certificate becomes "stale," and you must request a new one. Usually your computer will do this automatically and you won't even know it happened. This terminology is a bit strange. I can guess what you mean by a "stale" DHCP "certificate" but I'm not sure that everyone would. It sounds like something that someone made up. I could be wrong. -DJ Craig
How you can access to specific computer that locate withing wireless network?
You can use its IP address or network name (your firewall has to be configured properly).
What is the best definition of Information Security?
There are so many different conflicting definitions about Information Security out there; however there are clear censuses amongst the field's professionals and leaders on the following definition writing by Michael Chahino and Jason Marchant:
INFORMATION SECURITY is a discipline governing the framework for the continuous cycle of safeguarding information and ensuring related regulatory compliance.
- Discipline
• a branch of instruction and learning such as history, finance, economics
- Framework
• a frame or structure composed of parts fitted together documenting the methodology of incident identification, mitigation, and resolution much like the scientific method
- Cycle
• a series of processes that are repeated in a precise and deliberate manner
- Information
• electronic, printed, audible, visual, memorized
- Compliance
• ensuring that the institution is in compliance with applicable laws, regulations, and contractual agreements

What is the purpose of an organization's internal network?
The purpose of an organization's internal network is to ensure that everyone knows and understands the organizations goals and objectives. The internal network also ensures that the organizations provides quality service to those the organization comes in contact with.
Where is a good review on managed host server?
Reviews for managed host services can be found on sites like Webhosttalk, Hostreview, Webhostshop, Hostingindex, and Webhostsearch. For this in the UK reviews can be found on Fasthosts.
What is the purpose of transmission control protocol?
TCP (or similar protocols) take care of several generic tasks. For a start, they split a stream of data (e.g., a file) into small pieces, to make them manageable. The pieces are sent individually (in the case of TCP, the IP protocol is used for this), and numbered. The other end can verify that each of the pieces arrived, and request for missing pieces to be resent.
TCP also has the role of controlling network flow. That is, if the communications quality is too low, the speed is reduced; otherwise it may be increased.
TCP also takes care of starting and ending communications session.
Yet another role of TCP is to differentiate different communications between the same pair of computers. This is done via port numbers.
How do you shutdown a Cisco switch port?
If you want to shutdown a port on a Cisco 2960 Catalyst Switch you will need to connect to the router (either SSH, TelNet or connect using the Console cable) and enter the interface you want to shutdown. You will then need to enter the shutdowncommand. An example is given below for Fast Ethernet 0/2
Router> enable
Router# configure terminal
Router(config)# interface fa0/2
Router(config-if)# shutdown
Four Port Token Ring layer 2
How are private IP addresses handled on the internet?
Private IP Addresses are not used for internet data traffic but are intended to be used specifically on internal networks called intranets.
What types of network traffic do modern networks carry and how this changed human interactions?
wPorn. This has changed human interactions by increasing the amount of wanking the adult male does and decreases the amount of said time spent with his female counterpart.
Why are asynchronous protocols inherently slow?
They handle each character in a bit stream independently, They demarcate characters in transmission with start and stop bits, They apply variable-length gaps between characters in a transmission.
