System Performance: Unit 8 Edward Greene NT 1110 When addressing system performance, a key element that is often overlooked is Disk Fragmentation. Even on a brand new system with plenty of RAM and processing speed, the performance of the hard disk may be a bottleneck causing issues. It takes time to load large data files into memory - issues become particularly noticeable when dealing with movies, video clips, database files or image files which may easily be several gigabytes in size. On a

A port expander is a hardware device that will allow users to utilize multiple devices on a single port at the same time. It is the same principle as using a power strip for the power in a home or a splitter for the cable. For example, if you only have 1 Universal Serial Bus (USB) port, yet you have a USB mouse and keyboard, then you can use a USB port expander to allow one port slot to become multiple ports and plug in the mouse and keyboard. Allowing multiple devices to be able to connect to

Daniel Thompson 10/17/14 Computer Structure and Logic The major compenents of a motherboard are the processor (CPU). This is the 'brain' of the computer and is the chip where all the computing is done. Next is the memory. This is where the computer stores information while it is working on it. Computer memory these days is typically installed on long, narrow boards called SIMMs, or "Single Inline Memory Modules" into matching sockets. Next is the "Chipset". This is a loosely coined term that may

Deborah Collins NT110 – Prof Whitehead Unit 4. Assignment Video 04/14/14 Motherboards come in several form-factors. When building a system, it is important to know what it will be used for before purchasing. Two of the most important parts need to be considered before the system is built – the CPU and the motherboard. There are several different types of CPUs and motherboards, so care should be taken that the CPU can be seated on the motherboard. Also, think about what the computer will

An operating system (OS) serves primarily as a translator between the user and the applications and hardware of the machine in use. In this case the PC, tablet or mobile phone. The OS allows the user to easily visualize commands that prompt the software to carry out an array of functions, limited only by the hardware capabilities and the knowledge of its user. During the beginning stages of personal computer (PC) usage, IBM finalized a deal in the early 1980's with the most common household PC OS
