Fundamentals of Information Technology 1). How does an operating system ensure that hardware is used efficiently? Operating system can ensure processor to be used efficiently by the multiprogramming feature. Since the processor is fast while I/Os are slow, operating system needs to prevent processor from wasting time doing nothing and just waiting for I/O to complete. By having more than one program in memory, operating system will be able to let processor work on another program while the first

Technology plays significant role in today’s society. With advances in technology, the market of smartphones has experienced a significant growth since Apple introduced the iPhone in 2007. Technological advances have also paved way for wearable devices as the next generation of mobile technology. A wearable device is a small electronic device which can be worn on the body so that an individual can freely use it even when moving3. An example of such wearable technology is a smartwatch. A smartwatch

The CPU most determines how a PC performs, which is why finding the right computer processor is essential for making a system upgrade or starting a new build. It is important to buy a desktop processor that can handle the tasks you need your computer to perform. Equally as critical are budget considerations; you want the best CPU performance for the dollar, and do not want to pay for unneeded features. With hundreds of CPUs to choose from, options abound. Understanding how CPU specifications and

Geocaching app. Geocaching is able to use the phone to help the user find their cache, and as media changes this app has been able to not only stay relevant but begin to flourish. Geocaching is a relevant app because it unites the paradoxes of media, is a good

If the user of the PC is a hardcore gamer and he/she wants the games to play on high or ultra graphics settings without looking glitchy, or lagging out, then, the graphics card, RAM, and CPU are going to be the main focus of spending. Although if the user is just a casual gamer who doesn’t care about the look of the games he/she plays, and just really wants a computer for everyday browsing then the bare essentials are all that is needed

where i is a positive integer and N0 represents the LDM space size in demand when CHUNK is 1. Table III lists the applied CHUNK values in all WS/DMMPs schemes, where SP and DP represent the single and double precisions respectively In addition to directly accessing the main memory, the CPEs can also leverage the DMA engine to efficiently transfer data between their LDMs and the main memory. Compared with the direct access mode, DMA transfer has a broader bandwidth and thus cost less time. Besides
