Separating IT tasks (e.g., analysis, programming, operations) among different individuals to prevent fraud and error.

A situation where one person performs both input and output tasks, leading to increased risk of errors or fraud.

IT professional who designs and analyzes new computer information systems.

Restriction of access to data center operations, production programs, and data files for systems analysts to prevent unauthorized changes.

Person responsible for the overall database and controls to maintain integrity.

Additional controls used to mitigate risks where basic segregation is not possible.

Processes used to control and manage IT programs and assets, especially those used for testing.

A crucial measure to prevent unauthorized access to IT systems and resources.

The DBA (Database Administrator) has the sole responsibility for updating data dictionaries, ensuring data integrity and security.

In smaller systems, the DBA might manage some DBMS functions. However, in larger systems, the DBA uses a DBMS as their primary tool.

Programmers design, develop, test, and document programs based on analyst specifications, but they have no access to the data center or production data.

The webmaster manages website content and works with programmers and network technicians to ensure site availability and display.

Operators are responsible for the day-to-day operation of the data center, including loading data and running equipment. They should not have access to programming or systems design.

Help desks handle logged problems, resolve minor issues, and escalate complex issues to technical support.

Allowing programmers to modify both programs and data files creates a risk of unauthorized changes and data manipulation.

Operators should have limited access to documentation and programming knowledge to prevent them from making unauthorized changes to systems.

A system that plans and manages materials needed for production based on demand forecasts and schedules production accordingly.

To automatically generate purchase orders for parts, considering lead times, to ensure timely delivery and avoid production delays.

An advanced version of MRP that integrates all aspects of a manufacturing business, including production, sales, inventory, scheduling, and finances.

A statement outlining the anticipated production schedule for specific items over specific periods.

The master production schedule (MPS) is used in MRP II, and MRP is a component within that system.

A system where different subsystems share data and coordinate activities to streamline operations.

It allows marketing to quickly verify inventory availability and notify shipping to process orders efficiently.

When inventory is insufficient, the ERP system automatically notifies production to increase output and adjusts production schedules accordingly.

An IP address consists of four decimal-separated numbers, each ranging from 0 to 255. For example: 128.67.111.25.

DHCP allows for flexible and efficient use of IP addresses by assigning addresses dynamically to devices as they connect to a network.

A wireless network area, typically around a router, where devices can connect using Wi-Fi.

Wi-Fi avoids collisions by constantly searching for the best frequency within its range, ensuring smooth communication.

A network of devices, typically within a small range (about 30 feet), for a single user, enabled by the Bluetooth standard.

WiMax uses microwaves to create a large wireless network covering an entire city, acting as a 'hotspot' for many devices.

RFID uses a microchip with an antenna to store and transmit data about a product, pet, vehicle, etc.

RFID has various applications, including inventory tracking, lost pet recovery, and tollbooth collection.

Plans to ensure continuous operation of IT systems even when disruptions occur, like power outages or attacks.

Emergency power sources that automatically activate during power failures, ensuring continuous operation.

Cybersecurity threats requiring a controlled shutdown to prevent infection spread, followed by system recovery.

A backup location for IT operations in case of disaster, ensuring continuity of business.

A physical location for restoring IT operations in case of disaster, usually in a different city.

A fully functional ready-to-use backup data center, minimizing downtime.

The most expensive but least risky backup data center solution.

Organizations weigh the cost of contracting a backup facility against the cost of downtime due to disaster.

A process that simulates a disaster by loading backup data onto a hot site's equipment and measuring the time it takes to resume normal processing.

A backup facility with some resources available but requiring configuration and setup for the production system. It offers a quicker recovery time than a cold site but not as fast as a hot site.

A technology that ensures continuous operation in case of a hardware failure by using redundant components and software with backup power supply.

A technology that allows for data delivery along multiple paths, ensuring data availability even if one hard drive fails. Multiple drives work together, providing redundancy.

Computer systems designed with redundancy and backup power supply to minimize downtime, ensuring critical operations are uninterrupted.

Applications absolutely essential to an organization's operations, requiring constant availability and zero downtime. These systems cannot afford interruptions.
