Q1. Some of the computer applications that require connection oriented service include the remote login, file transfer and video on demand (Tanenbaum, Andrew, 13). Some of the examples of where the connectionless service is best include the electronic transfer of money, the verification of credit cards and most of remote database access.
Q2. The main reason for inventing the new abstract ID is because the process IDs is usually OS specific. This would make the protocols to become independent. The second reason for using the new abstract IDs is that one channel is capable of establishing multiple channels of communication. It is impossible to distinguish these channels when using the single process IDs (Tanenbaum, Andrew, 33)

Q4. This size of network design is because the network is suitable for medium organization. This make the size economical as a single router is capable of supporting several hosts (Tanenbaum, Andrew, 93). Communication in this size of a network is faster as the failure of one device does not affect the system. The system also makes it possible to use other connected devices such as printers.
Q5. The TPC is the personification of a transmission channel that is very reliable. It is used in end to end transmission purpose in the general internet architect. All the functionality of a network are required to take a simple of IP datagram release and major upon this control mode which helps in implementing flow control, reliability , sequencing , reliability and the manner in which data streaming is rooted with TCP(Tanenbaum, Andrew,103).
The TCP provides a channel of communication between different processes on every host system. The channel is usually very reliable and streaming. In order to achieve this functionality, the drivers in the TPC breaks up the running session DataStream into small segments and then attach them to the TCP header (Tanenbaum, Andrew, 112).

Likewise, a skeleton for transfer and exchanging blood within different parts of the body is considered veins. Similarly, for exchanging and communicating data within different computers and applications, computer network is an essential component. There are various types of computer networks such as Local Area Network, Wide Area Network and Metropolitan Area Network. These networks operates on different topologies, however, star...

...Interconnection (OSI) model. Likewise, network layer incorporates addressing information and control information that enables data packets to be routed within the computer network ("Internet Protocol Version 6." 255-255). Moreover, IP version 6 is also considered or called as the next generation IP, as specified by the IEFT: RFC 2460 ("Internet Protocol Version 6." 255-255). However, the primary reason for upgrading the IP version 4 to IP version 6 is address space limitations. Moreover, other issues such as performance, security and auto configuration are considered secondary (Loshin 305). Likewise, address space limitations are linked with the IP address space crisis that is debatable...

Introduction to Computer Networks TCPIP Although the protocol was defined before the commercial usage of LAN technologies, the original design has continued to work well through several generations of hardware technologies. IP is now used over networks that operate several orders of magnitude faster than the networks that were in use when IP was designed. The Motivation for Change In TCP/IP If IP works so well, why a need is felt to change The primary motivation for change arises from the limited address space. When IP was defined, only a few compute networks existed. The designers decided to use 32 bits for an IP address because doing so allowed the Internet to include over a million...

It has been describedby Network Working Group in their Request for Comments: 1305 specifications. NTP standardize the process of time synchronization between national time and frequency dissemination services helps in time synchronization of subnet of a network. It helps in adjusting the local clock in each participating subnet peer in a local network. It promises the accuracies of 1-50 ms, depending on the characteristics of the synchronization source and network paths. RFC-1305 specifies the NTP...

...) of the United States Department of Defense (DOD) was first intended to study and demonstrate computer resource sharing (Stallings 281). By 1975, it was no longer an experimental network and has been transformed to Defense Data Network, which met the DOD’s need demand for “secure command and control communications network and for ordinary unclassified communications” (Stallings 281). The outgrowth of ARPANET is what we know to be TCP/IP today. It is the communications protocol that unlike the Open Systems Interconnection (OSI) reference model recognizes the need for hierarchy. Its launch was a success because it delivered basic services that everyone needs like file...
