CHAPTER 2 LITERATURE REVIEW 2.1 Literature View Purpose Light Weight Directory Access Protocol (LDAP), is an application convention for perusing and altering registries over an IP system (Michelle & Christian, 2007). It is a standard innovation for system registries. Michelle & Christian (2007) declared that Network catalos are particular databases that store data about gadgets, applications, individuals and different parts of a PC system. It is not restricted to contact data or data about individuals. It is fitting for any sort of index like data where quick lookups and less successive redesigns exist. Donnelly (2008) uncovered that LDAP was made in 1995 as a scholastic college task, and afterward popularized by Netscape in the late 1990 's. It is discovering much acknowledgment due to its status as an Internet standard. It can likewise be tweaked to store any kind of content or twofold information. Note that it is not a registry yet a convention. Donnelly (2008) further clarified that LDAP arranges data in a various levelled way utilizing indexes. These indexes can store an assortment of data and can even be utilized like a System Information Service (NIS). NIS empowers anybody to get to their record from any machine on the LDAP empowered system. Much of the time, LDAP can be utilized additionally, as a virtual telephone index, permitting clients to effortlessly access contact data of different clients. Be that as it may, it is more adaptable than a telephone index. This
There is a mess of servers, switches, switches, and inward equipment firewalls. Each of the association's areas is working with diverse data advances and foundation IT frameworks, provisions, and databases. Different levels of IT security and access administration have been actualized and inserted inside their individual areas. The data engineering framework is maturing and numerous areas are running on antiquated fittings and programming. Additionally, the framework is woefully out-of-dated regarding fixes and overhauls which significantly expand the danger to the arrange as far as classifiedness, trustworthiness, and accessibility.
Individual users play an important role in any form of institution or organization but concerns are raised about the security. The network administrators clearly lay down a set of rules, regulations and protocols that an individual user has to agree accordingly upon which part of the resources and what class of service that the user can obtain.
Identifying and describing key features of operating systems and common application software as they relate to the management of information.
Coming in as a freshmen, I did not really put much thought into the symbolic meaning behind our mascot. However, after reading the thought process behind choosing it, I realized that there was more to the mascot then just being a three-headed dog. Historically, the Greeks saw the cerberus as a symbol of imprisonment to the dead; for students at KHHS, it is a symbol of protection, and for myself, the kerberos symbolizes determination and the passage to success. Historically, the Kerberos represented the imprisonment for the dead.
This is a IT service that through identifying and managing personal information, having access to collect data from application and computer resources. It is a better way for people to get convenience, especially for improving user productivity and reducing IT services. (Tufekci, 2008)
The Internet is, quite literally, a network of networks. It is comprised of ten thousands of interconnected networks spanning the globe. The computers that form the Internet range from huge mainframes in research establishments to modest PCs in people's homes and offices. Despite the recent hype, the Internet is not a new phenomenon. Its roots lie in a collection of computers that were linked together in the 1970s to form the US Department of Defense's communications systems. Fearing the consequences of nuclear attack, there was no central computer holding vast amounts of data, rather the information was dispersed across thousands of machines. A set of rules, of protocols, known as TCP/IP was
Improved Data Sharing: Data is retained by usual business processes and manipulated on a server is available for designated users (clients) over an authorized access. The use of Structured Query Language (SQL) supports open access from all client aspects and also transparency in network services depict that similar data is being shared among users.
Access control system is a system designed to control entry to prevent intruders into selected areas and manage movement of people/vehicles within. Its purpose is to increase security by determining who, when and where are they allowed to enter or exit.
EDM allows for the management of diverse types of document storage in an organization using collaboration software and storage ("IBM FileNet", n.d.). Each line of business has diverse business processes and procedures for storing and retrieving their internal documents. Each document that is loaded in the EDM system, IBM FileNet, is stored with particular metadata and retention record information. Choice lists are maintained to aid the user with data integrity and consistency. Furthermore, the document owners can request their file to be content-based retrieval enabled. This allows for keyword searches within the application to find documents based on keywords, not just metadata captured during the original load or check-in of the
The Case for this module centers on an organization implementing a new computer-based information processing system. Thousands of organizations go through the same kind of process every day—you yourself may have been involved in one or more such "technology transformations." Despite this body of experience; the advice of thousands of consultants, researchers, and computer gurus; and the leverage of multibillion-dollar corporations such as Microsoft, Google, and Oracle; a large proportion of these
Since shared data is in one location, it is easy to back up critical information. Though the server-based network demonstrates better performance and data handling, it is important to know that when the server goes down it takes the entire network with it. Unlike peer-to-peer networks server-based networks are more secure because security is handled for the network as a whole and not just for individual computers. Owing to these benefits, server-based systems are extensively used by large businesses and for various web
Before computers were invented, humans would store data in filing cabinets, safes, libraries, and other such places. However, the method of storing data changed when computerized databases were invented in the 1960’s [4]. Storing data in a digital database became more of a time and cost efficient method over storing data in filing cabinets or other like places. Computerized databases provide the user, or users, the ability to access, add, or remove data in a matter of seconds rather than the possible hours it could take, going through hundreds of physical folders.
Databases allow us to easily store and retrieve data in a purely digital format. The strength of this is that large amounts of data can be stored and retrieved with minimal effort on the part of the user. Opposed to manually flipping through files, one can quickly pull up the requested data through a computer program. Many systems that were conventionally paper and file based have been converted to a digital format which are now stored in one or more databases.
The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.
In the Distributed Operating System, different computers are connected together. With this kind of connection, the kind of topology in this system is hierarchical system. Hierarchical system topology, involves a server/client pattern that is used by the databases, distributed systems, and web servers (Grant, 2014). With this hierarchical system, information from different sources, root servers, flow to the next servers. Here different clients are connected and are able to receive and send their information.
