The company I work for, WesBell Electronics, only has 25 employees so I understand trying to save money and competing with much larger companies, however TSI is taking the wrong approach and their customers will soon find out. Similarly, TSI doesn't have a good fault tolerance because the system doesn't recognize problems and fix them unless it's specifically set up with a custom response. This create problems when developers need to make changes and repairs because each customer has different layout, and furthermore, when those developers leave the company it will be difficult for newly hired developers to get acclimated.
DEADLOCK AVOIDANCE IN OPERATING SYSTEM TSI DRIVERS
As a result anyone that can login to TSI headquarters can also login to any TSI server in the back office.ĭevice drivers are a big challenge for TSI because their developers write custom device drivers for each customer instead of having a standard format for all customers. When TSI is working on top secret alarm systems for government installations they should be able to discuss the amount of protection available through security measures, but they can't. Their customers shouldn't have to worry about the amount of virtual memory they're using, or how TSI needs to modify traps to kernel mode and develop custom system call responses.īased on the name of the company, Top Secret Inc., one might figure they have a good security system in place, but that's far from the truth. Virtual memory and TSI's system call interface create system crashes and compatibility issues. We'll look into a solution to these problems soon, but for now we're trying to determine the biggest problems and challenges of TSI's future. Instead, they should be updating technology and moving forward instead of backwards.
DEADLOCK AVOIDANCE IN OPERATING SYSTEM TSI SOFTWARE
They are buying old hardware to support single-core processors and using open-source software to limit what their customers can do. Multithreading is not something TSI can offer so they use open-source software to remove multithreading functionality which means TSI continues to run in the wrong direction. This is probably the main reason that many new software applications are licensed instead of each company trying to reinvent the wheel every time a new application arises. The issues TSI is having wouldn't be as significant if they were dealing with small companies as customers, but they are trying to support government agencies, Fortune 500 companies and the installation of top secret alarm systems.
A computer running excel and firefox browser simultaneously is an example of multiprogramming." Since there's only one processor at TSI, interrupts typically cause the operating system to lock up, and they're using old hardware with single-core processors because TSI doesn't support multicore processors. More than one task/program/job/process can reside into the main memory at one point of time. As The Crazy Programmer puts it, " Multiprogramming is the ability of an operating system to execute more than one program on a single processor machine. To the user, it appears that multiple programs are running at the same time, however, the processor is actually running part of one program and then part of another so quickly that it appears to be simultaneous. Multiprogramming is an important feature for Fortune 500 companies that may need more than on program running on one processor. Finally, TSI has little security in place and limitations with their software developers that are unable to program ideas for improvement.
DEADLOCK AVOIDANCE IN OPERATING SYSTEM TSI WINDOWS
TSI also cannot provide a CreateThread() API like Windows or Linux which can severely hurt their chances of getting new customers. For example, TSI's operating system doesn't support more than one program running at a time or more than one processor on a physical device. Even though TSI is known for their quick response time and highly reliable operation, they still need the latest and great technology to offer their customers. is an operating systems company that creates top secret alarm systems for government installations, camera systems for drone aircraft companies and control systems for Fortune 500 companies, but it's struggling to stay updated with technology since they use their own operating system created in-house.
