Prior to the introduction of the domain name system, computers use hosts files to map human readable names to ip addresses. A sub-net mask is used to separate the host address portion of an IP address from the network address. The sub-net mask within the TCP/IP configuration is used to distinguish the network address from the host address. In dotted-decimal notation, each Ipv4 address is broken into four octets. Server computers and other systems that need to be accessed reliably by network clients should be configured with a static IP address.
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
1. What is the Internet? The Internet is a globally interconnected network of computers that, operating via several specific protocols, serves as a worldwide information system and provides the technological infrastructure on which countless applications are run (Leiner et al., 2012; Woods, 2013a). At the hub of every network is a server, with the Internet essentially being formed through the connection of multiple servers, encompassing all connected computers and creating a larger ‘inter-network’ (Woods, 2013b). Each device on the network has a unique numerical address and the Internet uses the DNS (Domain Name System) to allocate each a corresponding human-readable address (Woods, 2013a).
With hypertext, a word or phrase can contain a link to another Web site. 3 What is a computer network? A collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another allowing for data to be shared and used. A great example of a network is the Internet. 4 What is the difference between an intranet and an extranet?
Most networks use __________________ to dynamically assign addresses and configure computers to use them. Dynamic Host Configuration Protocol (DHCP) 9. The Windows 7 utility that displays a list of the routers currently forwarding packets to a particular destination is called __________________. Tracert.exe 10. The top and bottom layers of the OSI model are called the __________________ and ________________ layers.
In computer science, a communications protocol is a system of digital rules for message exchange within or between computers. Communicating systems use well defined formats for exchanging message. With every message there is an exact meaning that has an intention to bring out a certain reaction to the receiver. A protocol must describe the syntax, semantics and the synchronization of communication. Think that a communication protocol is like a Standard of Operations Manual (SOP).

Question 4 What is the name of the computer you are working from? SEA-SVR2 Question 5 What IP addressing settings are currently configured?
What data elements are and why they are important There are two different types of data elements such as: 1) Elementry data elements - Defined by the built in values of data type and lenght 2) Reference data elements - Make use of reference variables mostly used in other ABAP objects Data element is a data dictionary which can be created or modifed by using a process which is called SE11. The purpose of data elements are they are designed to find the characteristics of a table field or a component of a structure. Data element is a term where a process of the functions take place over networks just like protocols. Frames and Packets: To avoid delay during the process of transmitting data to another network, the networks change the amount of data that can be transferred across which is called switching. The amount of units that the data is sent in is called packets.
