Multiprogramming

Tech Description

Multiprogramming is a feature that allows multiple programs to run simultaneously on a computer system. It is achieved by allocating the CPU's time among multiple processes

Business Requirement

The absence of multiprogramming in TSI's OS restricts the ability to run multiple back-office applications concurrently. This impacts efficiency and leads to increased operational costs

Multiprocessing

Tech Description

Multiprocessing involves the use of multiple processors or cores to perform tasks in parallel. It enhances the system's ability to handle multitasking and improves overall performance

Business Requirement

TSI's OS lacks multiprocessing support, leading to underutilized server infrastructure and increased operational costs. This feature is crucial for efficient resource allocation.

Multithreading

Tech Description

Multithreading allows multiple threads within a process to execute concurrently. It is essential for handling tasks that require parallel execution

Business Requirement

TSI's OS's lack of multithreading negatively affects the performance of multithreading-heavy back-office applications, causing delays and disruptions. This impacts operational efficiency and competitiveness

Virtual Memory

Tech Description

Virtual memory is a memory management technique that uses disk space to extend physical RAM. It prevents system crashes due to memory shortages

Business Requirement

TSI's OS experiences frequent failures without paging, resulting in server outages and reduced productivity. Addressing this issue is crucial to maintaining a stable and reliable server architecture.

System Call Interface

Tech Description

The system call interface provides an interface for applications to request services from the operating system. It allows programs to interact with the kernel.

Business Requirement

While not mentioned specifically in the text, the absence of a system call interface would greatly impact the ability of applications and processes to interact with the OS, affecting the overall functionality and efficiency of the system

Security

Tech Description

Security features include login authentication, file system security, and network security. These features protect the system from unauthorized access and data breaches.

Business Requirement

TSI's OS lacks these security features, posing a risk to data and system integrity. Unauthorized access to back-office servers is a significant security concern that needs to be addressed.

Device Drivers

Tech Description

Device drivers are software that allows the operating system to communicate with hardware devices. They are essential for hardware compatibility

Business Requirement

TSI's challenge with custom device driver development for various devices impacts compatibility and system efficiency. Without proper device drivers, data loss risks increase, and reliability is compromised.

Fault Tolerance

Tech Description

Fault tolerance involves the system's ability to continue operating in the presence of hardware or software failures without data loss.

Business Requirement

The lack of fault tolerance, as in the case of TSI, increases the risk of data loss during hardware failures. To maintain data integrity and business continuity, TSI needs a reliable backup and recovery strategy.
