what is semaphore??? | Operating Systems | ICT Trends

what is semaphore???

Semaphore is essentially a kind of locking mechanism that help us achieve synchronization and mutual exclusion while building concurrent programs.

A semaphore is a programming construct that helps us achieve concurrency, by implementing both synchronization and mutual exclusion. Semaphores are of two types, Binary and Counting.

A semaphore has two parts : a counter, and a list of tasks waiting to access a particular resource. A semaphore performs two operations : wait (P) [this is like acquiring a lock], and release (V)[ similar to releasing a lock] – these are the only two operations that one can perform on a semaphore. In a binary semaphore, the counter logically goes between 0 and 1. You can think of it as being similar to a lock with two values : open/closed. A counting semaphore has multiple values for count.

What is important to understand is that the semaphore counter keeps track of the number of tasks that do not have to block, i.e., they can make progress. Tasks block, and add themselves to the semaphore’s list only when the counter is zero. Therefore, a task gets added to the list in the P() routine if it cannot progress, and “freed” using the V() routine.

Now, it is fairly obvious to see how binary semaphores can be used to solve synchronization and mutual exclusion – they are essentially locks. [Ref]

Wonder how I access and Manage my VPS? These are the simple tools!

Once you buy VPS to host your Blog, you need a few tools so that you can access and manage it comfortably. In this post, I briefly discuss about the basics of VPS and reveal the tools I’m using to access and manage my VPS. You are welcome to join the discussion and offer some recommendations if you have.

Source: bivori.com

To host your blogs, having your own VPS offers some enticing benefits over the hindrances in shared hosting (see Why I switched from HostGator shared account to DigitalOcean VPS). Economical, Total control over your blog, flexibility and scalability, dedicated IP address (free from bad neighborhood) are some of the startling benefits you can’t ignore.


Setting up some of these tools in your PC is a comfort while accessing and managing your VPS (Virtual Private Server). This is an attempt to let you know it earlier before you draw wrong conclusion that managing VPS is an impossible task!  For this post, I assume you are a complete novice entering into the VPS and Linux world very recently. I hope it will help you to be aware of the tools you need to manage and monitor your VPS remotely.

HostGator to DigitalOcean – Why & How for WordPress Blog

Finally successful to move my wordpress blogs from shared hosting of HostGator to DigitalOcean VPS hosting. Find here why and how I did the migration.

Source: bivori.com

I used ‪#‎HostGatgor‬ for quite long time and always believed that I selected the best hosting provider. I’m sure many of you too are proud to use HostGator or BlueHost or any other shared hosting. But are you aware of following fact? I heard about VPS but it was always out of my list thinking it is expensive and complicated to mange. I don’t know about Linux and no idea to installing and configuring servers. Now I use ‪#‎DigitalOcean‬ an unmanaged VPS server for $10/month (this is same as Baby Plan in HostGator, isn’t it? I choose the plan because I already have 3 blogs to host but you can start with $5 plan. Click the link below to read my story and make better decision – Do you still need to continue using shared hosting? http://bivori.com/hostgator-to-digitalocean/

While developing a new (software) system or upgrading an existing one (to automate any organization), there requires creating new software applications at the frontend and a well designed database at the backend.

This post describes conceptual database model in the context of software development life cycle and database design. It defines, explains and lists the features of conceptual database mode.

Click the title above to visit and read the post.

Suresh Khanal‘s insight:

A conceptual data model is a summary-level data model that is most often used on strategic data projects. In simple words, it is the most simple representation of database you are going to develop. It typically describes an entire enterprise.  Due to its highly abstract nature, it may be referred to as a conceptual model.
