Final Exam of Computer Networks (ICE 1230) 2008.5. 27. Answer in English and Total 15 points 1. Why is it said that packet switching employs statistical multiplexing? Contrast statistical multiplexing with the multiplexing that takes place in TDM. (1 point) Answer: In a packet switched network‚ the packets from different sources flowing on a link do not follow any fixed‚ pre-defined pattern. In TDM circuit switching‚ each host gets the same slot in a revolving TDM frame. 2. In BitTorrent

Network Security Concepts Name NTC 410 Instructor ’s Name November 1‚ 2005 File security falls into two categories‚ encryption and access. Access to files can mean physical access to a computer with unsecured files or access via user permissions or privileges in the form of access control lists (ACLs) (Strengthen Your Users ’ File Security‚ 2003). The files kept on a server with NTFS storage can be locked to prevent anyone who does not have the correct permissions from opening them. This is

frequencies satellite networks are able to provide broadband services requiring wider bandwidth than the current services at C or Ku-band. As a consequence‚ some of the new services gaining momentum include mobile services‚ private intranets and high data rate internet access carried over integrated satellite-fiber ATM networks. Several performance issues need to be addressed before a transport layer protocol‚ like TCP can satisfactorily work over satellite ATM for large delay-bandwidth networks. In this paper

Sample of an Upward Network One major advantage to using the upward network¬ is that with well-established lines of communication all feedback such as suggestions and complaints alike can be submitted and responded to and direct feedback can be given in a timely manner. Another perk of this particular upward network would be the protocol of how one would submit a request to any chosen channel within an organization. One more perk of the upward network would be the efficiency in the

Converged network adapter From Wikipedia‚ the free encyclopedia A converged network adapter (CNA)‚ also called a converged network interface controller (C-NIC)‚ is a computer input/output device that combines the functionality of a host bus adapter (HBA) with a network interface controller (NIC). In other words it "converges" access to‚ respectively‚ a storage area network and a general-purpose computer network. "Converged" network adapter diagram Contents [hide] 1 Support 1.1 Brocade
