GOTO is the structure that causes the logic to jump to a different place in the program. The IF statement allows the programmer to control a program entering a section of code or not based on whether a given condition is true or false. An important function of the IF statement is that it allows the program to select an action based upon the users input.

Unit 1 Assignment 1.1 Identification, Authentication, and Authorization Techniques There are numerous techniques that the Information Technology industry can use in order to substantiate an entities identity, have the ability to authenticate that entity and provide the appropriate authorization for that entity to have access to a networks resource. There are many diverse techniques that are obtainable to accomplish this task. First of all we need to define what authentication accurately is. Authentication is the ability to verify the identity of a user or a computer system on a computer network. (Barker, 2013) There are many forms or variations that authentication can manifest itself depending on the requirements as outlined in the Security Policy published by the business.
Unit 3 Definitions 1. Logic Design - A logical design is a conceptual, abstract design. You do not deal with the physical implementation details yet; you deal only with defining the types of information that you need. 2. Physical Design - the physical design of the database specifies the physical configuration of the database on the storage media.
What is more, even though Navistar tries to communicate necessary information to its supplier, Trimco has little ability to control or monitor its outgoing parts due to the limited centralization, standardization and computer system capability. In order to establish a more defined structure and process and thus solve the problem of trim parts shortage, it is suggested to implement a proper software, such as ERP, for both Narvistar and Trimco. Since the ERP system is based on a common database and a modular software design, which allows every function of business to store and retrieve information, any changes that Narvistar inputs into the system will be automatically reflected and received by Trimco. Besides, it is easier for Trimco to get into the database regularly and see if there is any new information changed by
Also, with the old system, there was no physical control over the supplies. Dishonest employees at a particular motel could steal supplies much easier than under the new
Compared to object oriented languages they are more orderly than object oriented languages. Object oriented languages can be abstract in nature. Object oriented programming has its own problems with encapsulation. If the code is hidden from a programmer trying to use or modify the encapsulated code, then the code is essentially useless (Mansfield, 2014). Even if encapsulation creates some security, it might secure the programmer against making changes.
Relocation is executing processes separately from physical memory and is handled through paging, partitioning, or segmentation. a. Paging is when the memory is fixed into small equal chunks. The strength in paging is seen in no external fragmentation, but it can cause some internal
General data pertaining information on logins will only hold aggregate statistics such as the number of logins in a day and the number of failed logins. An employee database will be created logging all necessary information which will be kept separate from other databases. The reason for this is that employee information is not required for operations to run efficiently therefore it will not be linked. Data collected on paper from stakeholders such as data collected from surveys for market stall holders, will be
