Just last year in 2013, the price per bit for ram storage is not even pennies. (My calculator doesn’t go that far, ha.)
2) Modified page can be written out in clusters rather than one at a time, significantly reducing the number of I/O operations and therefore the amount of disk access time. 10 Why is it not possible to combine a global replacement policy and a fixed allocation policy? The short answer is because those two methods have conflicting goals. Fixed allocation implies the number of pages allocated for each process is "fixed". Global page replacement implies the number of pages allocated for the system is fixed and the number allocated to each process can
3. Identify the processor model and year when two billion transistors were placed on a single processor chip. * In 2008 * The next generation in the Intel Itanium processor family code named Tukwila is described. The 21.5 mm by 32.5 mm die contains 2.05 billion transistors, making it the first two billion transistor microprocessor ever reported. Tukwila combines four ported Itanium cores with a new system interface and high speed serial interconnects to deliver greater than 2X performance relative to the Montecito and Montvale family of processors , .
The Industrial Era - The fourth generation of computers 1986-1988 The Fourth generation of computers relates to the present era of computers. These computers are defined by entirely electronic and programmable models in which ICs (integrated circuits) are constructed constituting above 500.000 components. Thus, the FOURTH GENERATION of computers commenced with the birth of the microcomputer. • In the present era more than one standard silicon based CPU will see the light. • Light based processors see literally the lights in laboratory.
5. What are the minimum system requirements for Fedora 15 with the GUI installed? The minimum system requirements for Fedora 15 with GUI is: Intel Pentium Pro processor with 400 megahertz. RAM 384-512 mebibytes. Hard disk space can be as little as 90 mebibytes.
d. Kilobyte 3. Which answer lists the correct number of bits associated with each term? c. 64 bits per quadruple wor 4. Which of the following answers are true about random-access memory (RAM) as it is normally used inside a personal computer? (Choose two answers.)
Chapter 4: Mini-Cases IV Alpha Corp 1. Without considering transmission efficiency, I would recommend installing an internet source capable of transmitting 270,000 bits per second or higher for the Alpha Corp. The Alpha Corp is transmitting 1,000 emails per hour at 1,500 bytes in size, which equals 16.6 emails per minute. This then breaks down to 0.277 emails per second sending 415.5 bytes per second or 3,324 bits per second . Alpha also sends 3,000 Web pages per hour at 40,000 bytes in size, equaling 50 emails per minute or 0.833 per second.
Why do you think the world is running out of IPv4 addresses? The internet really started in the 70s as a DARPA research project. At the time, there were 60 or so institutions expected to connect. As the interested research community grew, the addressing scheme was expanded from 8 bits (256 addresses in the predecessor to Internet Protocol (IP) known as Network Control Protocol (NCP)) to 32 bits (the IPv4 addresses we have today). At the time, it was still expected that the internet would serve largely defense, research, and educational institutions.
Windows Server 2008 packages information about system activities into individual units called (events.) 9. A hardware or software component that is operating below par, slowing down the performance of the system, is called a (bottleneck.) 10. To view the Windows Server 2008 system logs, you must use the (Event Viewer snap-in.)
Quantum computers have the potential to perform certain calculations significantly faster than any silicon-based computer. If you will try to compare modern computers with early computers you would see and feel huge difference, because early computers could do only simple operations, not to mention today's games and various programs. It was impossible to imagine what operations could do computers in the future. Let me give you an example of thoughts about the future computers: “Computers in the future will weigh no more than 1.5 tons” – quoted in popular Mechanics in 1950. What do we see now?
