An introduction to operating systems, covering processes, states of processes, synchronization, programming methods of synchronization, main memory, secondary storage and file systems. Although the book is short, it covers all the essentials and opens up synchronization by introducing a metaphor: producer--consumer that other authors have employed. The difference is that the concept is presented without the programming normally involved with the concept. The thinking is that using a warehouse, the size of which is the shared variable in synchronization terms, without the programming will aid in understanding to this difficult concept. The book also covers main memory, secondary storage with file systems, and concludes with a brief discussion of the client-server paradigm and the way in which client-server impacts the design of the World-Wide Web.Shipping Notes

Fun toy for dogs
Color: Dim Sum Dumpling Pet Toy Set
My dogs enjoyed them. They didn’t last long, but it’s not due to the quality of the toy. My dogs are very hard on toys, so this was affordable. You get 3 toys and I have 3 dogs. Win win.

Pups all time FAVORITE!
Color: Dim Sum Dumpling Pet Toy Set
Our pups FAVORITE “ball”. He’s obsessed and has a blast with these little dumplings. Small size toy, but our medium labradoodle loooves them. Not to loud of an squaek either. They last quite awhile before he pops the squeaker. Fabric holds up really well.

Great squeaky fetch toy for small dogs
Color: Dim Sum Dumpling Pet Toy Set
My dog loves these little squeaky dumpling toys. They are the right size for small dogs (under 20 pounds) to chase and fetch, and they have good squeakers inside. They have a friendly look and my dog can fit them in her mouth.
