It can be changed from the Network Utility TCP/IP properties. 2. What are the difference between clustered and a non-clustered index? 1. A clustered index is a special type of index that reorders the way records in the table are physically stored.
The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding who gets memory, when they receive it, and how much they are allowed. When memory is allocated it determines which memory locations will be assigned. It tracks when memory is freed or unallocated and updates the status. Paged allocation divides the computer's primary memory into fixed-size units called page frames, and the program's address space into pages of the same size.
See Section 14.1. 14.2 Describe the main phases involved database design. Conceptual database design – to build the conceptual representation of the database, which includes identification of the important entities, relationships, and attributes. Logical database design – to translate the conceptual representation to the logical structure of the database, which includes designing the relations. Physical database design – to decide how the logical structure is to be physically implemented (as relations) in the target Database Management System (DBMS).
A two way system of saving is used here. Firstly for the database system, the user details for registration are stored in it while for the flat file system the documents uploaded may be stored there using pointer to create a specific name for a group of documents as the user prefers to save it. 3.10 System Implementation Tools We used software development tools and Languages to accomplish our goals and objectives of the system. We make elaboration on Front-End Languages and Back-End Servers. 3.10.1 Code Editors and Tools
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). Information is requested from a server and is sent using the packet switching and TCP/IP (Transmission Control Protocol/Internet Protocol) system (Jamison, 2001; Woods, 2013b). This involves breaking large files into smaller ‘packets’, allocating each packet addressing information, and sending them via different routes to be reassembled – including verification – at their destination (Jamison, 2001). Constantly evolving, the Internet has become an all-encompassing social, communicative and collaborative tool that is arguably essential to modern life (Leiner et al., 2012). 2.
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.
Assignment 3: Databases Professor David Moore Course Title: CIS 106: Introduction to Technology 28 May 2014 Assignment 3: Databases A relational database is a compilation of data items arranged as a group of tables from which data can be evaluated or reconstructed without needing to rearrange the database tables. A database is comprised of one or more tables of data. The rows in a table are called records, and the columns in a table are called fields or attributes. A database that holds one table is called a flat database, and a database that is comprised of two or more related tables is called a relational database. The Historical Data Warehouse design permits successive automatic transformations to obtain one of the implementations of the model in a Relational Data Base Management System [RDBMS] (Neil, De Vincenzi, and Pons, 2014).
h. T 9) In a diagram, crows feet notation conveys more information about the relationships. i. T 10) A primary key uniquely identifies each row in a database table. j. F 11) In a relational database, all data is kept in tables, even the information about the tables. k. T 12) SQL is the language used by relational databases to create objects and to manipulate and retrieve data. l. T 13) An entity is someone who is interested in the database.

Jabra Desktop Administration Unit 2 Essay Questions 1. Describe situations in which you would configure your network as a workgroup and as a domain. A workgroup is a logical group of computers that are interconnected, generally over a local area network. Workgroups allow users to easily share information and resources. A workgroup is also referred to as a peer-to-peer network.
The unit can compare numbers, letters, or special characters. The computer can then take action based on the result of the comparison. It then has a memory unit which allows the CPU via the operating system to calculate the amount of memory needing to be allocated to each programme and where to put the memory in use if unallocated. The processor can also control backing storage this is sometimes knows as secondary storage this is the name for all other data storage devices in computer i.e. a hard drive, etc.
