TCP/IP is quickly becoming the networking protocol and is the one I concentrate on in this subject. B) Network services To be of use to users the network will provide various services including file, print and device sharing, electronic mail etc. 1.3 TYPES OF NETWORKS A) Network categories · LAN (local ... ... middle of paper ... ...UNIX the routing table can be viewed using the netstat command. The route a packet follows can be viewed using the traceroute command. Routing tables are either created statically, or by the systems administrator configuring the system, using the startup or configuration fiels, to used a pre-defined, unchanging route.dynamically.
TCP/IP Name Affiliation Date TCP/IP Introduction TCP stands for Transmission control protocol while IP stands for Internet protocol. They are merged together to form the Internet protocol suit which is a model for networking which consists of communication protocols which are used for internet and other similar networks. This protocol suite was designed and developed by the Department of Defense (DoD). It was developed in order to connect different networks which were designed by different vendors. By use of TCP/IP, several computers on small network in a department can use these protocols in conjunction with other protocols on a single LAN.
Networked PCs are a great example. Tasks are accomplished at the computer and at other computers using communication. In the definition of a network the computer hardware is considered part of the user in this definition. The hardware used to connect to other computers is considered part of the protocol.
TCP/IP Overview When designing networked applications one key protocol stands out as the foundation for making it possible. That protocol is TCP/IP. There are many protocols out there that allow two applications to communicate. What makes TCP/IP a nice protocol is that it allows applications on two physically separate computers to talk. What makes TCP/IP great is that it can do with two computers across a room or across the world.
Routers primarily route data packets to other networks. They provide the interfaces between external and internal networks (the Internet and a LAN, for example). A router usually contains other functions such as firewalls, traffic monitoring, VPN, and more services. Security Review According to the SciTechConnect blog , “In today’s network infrastructures, it is critical to know the fundamentals of basic security infrastructure. Before any computer is connected to the Internet, planning must occur to make sure the network is designed in a secure manner.
The main function of the switch, router, gateways, or hubs is having the ability to process and forward data packets on the network. The creation and function is to ensure that each having their own unique functions and configurations which makes one a more viable optional choice over the next for ensuring data forwarding. For example, large networks will need routing protocols that will send the data packet to the intended destination and not broadcast it throughout the entire network. Gateways provide nodes with a contactless connection into the resources that are available for the users. The basic gateways that are installed in many pc are called NIC’s or network interface card (Andrews, 2006, pp.
In the case of a network protocol, it is a set of rules by which computers communicate. The term "protocol suite" describes a set of several protocols that perform different functions related to different aspects of the communication process. Cisco IOS software which runs on Cisco equipment and devices, is the industry-leading and most widely deployed network system software. It delivers intelligent network services for enabling the rapid deployment of Internet applications. Cisco IOS software provides a wide range of functionality, from basic connectivity, security, and network management to technically advanced services.
Topologies need to be thought out and categorized according to the layout of equipment and computers(star, loop, bus, or mesh). 2.

The host names and NetBIOS names often just called computer names. 4.
Application software consists of computer programs that interface with network users and permit the sharing of information, such as files, graphics, and video, and resources, such as printers and disks. Network software consists of computer programs that establish protocols, or rules, for computers to talk to one another. These protocols are carried out by sending and receiving formatted instructions of data called packets. Protocols make logical connections between network applications, direct the movement of packets through the physical network, and minimize the possibility of collisions between packets sent at the same time. These are some of the different types of Network software: Appletalk, Arpanet, Bitnet, CWIS, Ethernet, IBM Token Ring netwrok, Internet, LAN, and USENET.
While TCP/IP is quite complicated, it is the most versatile protocol around. Some commonly used notions that surround TCP/IP management is that generally with TCP/IP, a client-server mode of operation is used. To run the TCP/IP server software, a gateway is used. A controlling host will run the client software. Also, an authentication method is needed to access to the server.
