MULTITASKING

Answer 10

The concurrent use of the same computer to accomplish several different information processing tasks. Each task may require the use of a different program or the concurrent use of the same copy of a program by several users.

Answer 13

place to store data with has a strategic relevance

Question 14

EXTRANET

Answer 14

• A network that links selected resources of a company with its customers, suppliers, and other business partners, using the Internet or private networks to link the organizations’ intranets.

Question 15

DATABASE MODELING

Answer 15

A process in which the relationships between data elements are identified and defined to develop data models.

Question 16

FILE SERVER OR NETWORK SERVER

Answer 16

In computing, a file server is a computer attached to a network that has the primary purpose of providing a location for shared disk access, i.e. shared storage of computer files (such as documents, sound files, photographs, movies, images, databases, etc.) that can be accessed by the workstations that are attached to the same computer network. The term server highlights the role of the machine in the client–server scheme, where the clients are the workstations using the storage. A file server is not intended to perform computational tasks, and does not run programs on behalf of its clients. It is designed primarily to enable the storage and retrieval of data while the computation is carried out by the workstations.

File servers are commonly found in schools and offices, where users use a LAN to connect their client computers.

Question 17

PROTOCOL

Answer 17

The Transmission Control Protocol (TCP) is one of the core protocols of the Internet protocol suite (IP), and is so common that the entire suite is often called TCP/IP. TCP provides reliable, ordered, error-checked delivery of a stream of octets between programs running on computers connected to a local area network, intranet or the public Internet. It resides at the transport layer.

Web browsers use TCP when they connect to servers on the World Wide Web, and it is used to deliver email and transfer files from one location to another.

Question 18

NETWORK TOPOLOGIES

Answer 18

Network topology is the arrangement of the various elements (links, nodes, etc.) of a computer network.[1][2] Essentially, it is the topological[3] structure of a network, and may be depicted physically or logically. Physical topology refers to the placement of the network’s various components, including device location and cable installation, while logical topology shows how data flows within a network, regardless of its physical design. Distances between nodes, physical interconnections, transmission rates, and/or signal types may differ between two networks, yet their topologies may be identical.

A good example is a local area network (LAN): Any given node in the LAN has one or more physical links to other devices in the network; graphically mapping these links results in a geometric shape that can be used to describe the physical topology of the network. Conversely, mapping the data flow between the components determines the logical topology of the network.

Question 19

WHAT IS A SOURCE CODE?

Answer 19

In computer science, source code is any collection of computer instructions (possibly with comments) written using some human-readable computer language, usually as text. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. The source code is often transformed by a compiler program into low-level machine code understood by the computer. The machine code might then be stored for execution at a later time. Alternatively, an interpreter can be used to analyze and perform the outcomes of the source code program directly on the fly.

Question 20

What is EIS, Exec Info system

Answer 20

system that allows good/challenging analysis that requires little IT knowledge - An executive information system (EIS) is a type of management information system that facilitates and supports senior executive information and decision-making needs. It provides easy access to internal and external information relevant to organizational goals. It is commonly considered a specialized form of decision support system (DSS).[1]

EIS emphasizes graphical displays and easy-to-use user interfaces. They offer strong reporting and drill-down capabilities. In general, EIS are enterprise-wide DSS that help top-level executives analyze, compare, and highlight trends in important variables so that they can monitor performance and identify opportunities and problems. EIS and data warehousing technologies are converging in the marketplace.

Question 21

WHAT IS A MANAGEMENT INFORMATION SYSTEM

Answer 21

• A management support system that produces prespecified reports, displays, and responses on a periodic, exception, demand, or push reporting basis

A management information system (MIS) provides information that organizations require to manage themselves efficiently and effectively.[1] Management information systems are typically computer systems used for managing five primary components: 1.) Hardware, 2.) Software, 3.) Data (information for decision making), 4.) Procedures (design,development and documentation), and 5.) People (individuals, groups, or organizations). Management information systems are distinct from other information systems, in that they are used to analyze and facilitate strategic and operational activities.[2]

Academically, the term is commonly used to refer to the study of how individuals, groups, and organizations evaluate, design, implement, manage, and utilize systems to generate information to improve efficiency and effectiveness of decision making, including systems termed decision support systems, expert systems, and executive information systems.[2] Most business schools (or colleges of business administration within universities) have an MIS department, alongside departments of accounting, finance, management, marketing, and sometimes others, and grant degrees (at undergrad, masters, and PhD levels) in MIS.

Question 22

Information processing instructions

Answer 22

A concept that covers both the traditional concept of processing numeric and alphabetic data and the processing of text, images, and voices. It emphasizes that the production of information products for users should be the focus of processing activities.
