it was based on two main components: a central processing unit (CPU) and a storage structure (memory). This is the basis of most computers in use today. The purpose of this architecture was to show how a computer would access and run stored programs that contain programmed instructions and data. These are stored in random access memory (RAM), which can be read from and written to, similar to today’s computer RAM. Originally, the CPU was broken down into two components: the control unit and the arithmetic

tend to come and go. The way a CPU is organized varies, but here are the basics: The motherboard system bus carries information into and out of the CPU. When the system bus enters the CPU, it’s called a Front side bus. The Front side bus usually uses a 64-bit wide data path. On the side of the CPU you will find a controller. A controller manages the basic functions of the CPU, and controls communication between the motherboard and other components within the CPU. These other components includes

An Analysis of Linux Scalability to Many Cores Silas Boyd-Wickizer, Austin T. Clements, Yandong Mao, Aleksey Pesterev, M. Frans Kaashoek, Robert Morris, and Nickolai Zeldovich MIT CSAIL A BSTRACT This paper analyzes the scalability of seven system applications (Exim, memcached, Apache, PostgreSQL, gmake, Psearchy, and MapReduce) running on Linux on a 48core computer. Except for gmake, all applications trigger scalability bottlenecks inside a recent Linux kernel. Using mostly standard parallel programming

• Task I 2. The LGA 1156 motherboards are for use with Intel H1 processors. The LGA 1156 connector’s main purpose is to connect the processor to the motherboard for use with the PC. 3. The H55 chipset is the first generation of the Intel I-series. It is compatible with LGA 1556 motherboards. 4. Some of the Gigabyte GA-H55M-UD2H ‘s unique features are on/off charge for best ipod/android charging, 2oz copper PCB, and smart 6 technology along with more common though no less useful features like USB

Worksheet The Central Processing Unit (CPU) is one of the most important parts of a computer system. It has a huge impact on the overall performance of any computer. If you have the opportunity, it is better to select the CPU before selecting the motherboard. Existing motherboards limit your choice of CPUs, forcing you to fit the CPU to the motherboard. If the performance of the computer is crucial to the successful completion of a task, then choosing the CPU first is especially important; for example

Intel® Core™ i7-800, Intel® Core™ i5, and Intel® Core™ i3 processors. Its purpose on the motherboard is it determines the type of processor the motherboard accepts, the type of capacity of RAM, and what sort of internal & external devices the motherboard supports. It serves as an electronic interface through which the CPU, RAM and I/O
