CIST1122 Lab 5: Supporting Processors and Memory NAME: Billy Tweedell DATE: 03/03/14 Research the Web If Necessary Scenario: You Are Working on a Desktop Computer 1) Why is it important to double-check the bottom of the heat sink before attaching it to the CPU socket? To insure the surface is clean 2) What is the purpose of benchmarking? In this case to test the limits of a processor 3) Why might you want to upgrade RAM on a system? To improve performance 4) Why is it important to match the latencies

What was the most significant event in the life of the DDR? Germany was never meant to split up. The significant things were communism‚ the division‚ the fall of the berlin fall and control. We can’t really point to a significant event. More importantly‚ most of the changes that took place in the life of the GDR were forced upon it from outside – crushing the Berlin workers rising‚ building the Berlin wall and the end of the soviet union were all external. Germany was split into two countries‚

1. INTRODUCTION Mobile computing has been the buzzword for quite a long time. Mobile computing devices like laptops‚ webslates & notebook PCs are becoming common nowadays. The heart of every PC whether a desktop or mobile PC is the microprocessor. Several microprocessors are available in the market for desktop PCs from companies like Intel‚ AMD‚ Cyrix etc.The mobile computing market has never had a microprocessor specifically designed for it. The microprocessors used in mobile PCs are optimized

this computer. Sony chose the Intel 915P Express Chipset which runs the PC3200 DDR SDRAM at an harmonious 400 Mhz. I was also very excited that they chose the Double Data Ram as oppose to the normal SDRAM. The computer comes with a 1GB stick of ram‚ however‚ I am going to add another stick of Kingston 1Gb ram to max out the ram capacity at 2 gigabytes. And since it’s DDR its going to be running like it has 4GB’s of SDRAM. The hard drive is a very hefty one with almost 400 gigabytes of space.

MEMORY PCs have quite a bit of memory of different kinds. Let’s take a look at some general concepts that will help us understand what we are talking about when we say “memory.” Storage One of the things we expect our PCs to do is to store information. This information can be our data files‚ it can be our application software‚ or our operating system. If this information were not stored in the PC itself‚ we would have to re-install it every time we turned on the PC‚ and then it would have to

memory)‚ since it loses its data when power is removed. The transistors and capacitors used are extremely small—millions can fit on a single memory chip. • DDR SDRAM Double data rate synchronous dynamic random access memory (DDR SDRAM) is a class of memory integrated circuits used in computers. Compared to single data rate (SDR) SDRAM‚ the DDR SDRAM interface makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals. Implementations often have

Unit 6 – Storage Devices & Memory Videos 1.06 and 1.08 covered Storage Devices and Memory. The 1st one covered all the different types of storage devices. It started with hard drives and went on to floppy drives‚ cd’s‚ dvd’s‚ solid state removable and tape drives. It also covered all the interfaces that can be used with them. The video also touched on power connections used to power up the different storage devices. Video 1.08 covered memory. It went through the two different types of memory

Computer Systems Assignment. Task 1. (A computer system is made up of a variety of internal and external components‚ describe the components and their function‚ how they communicate with each other and what different types are available.) Computer systems recently have essentially been split into three categories in terms of hardware. There is the basic build‚ which accommodates smaller and more basic equipment that is ideal for office use or personal computing. There is then a stylish and fast
