NT 1110 Unit 8 System Performance When addressing system performance an element that is often overlooked is disk fragmentation, even on a brand new system with plenty of RAM and a high end processor the performance of the hard disk may be a bottleneck causing performance issues. When you format a hard disk the process divides the disk into sectors, the file system groups the sectors into clusters which is the smallest unit of space available for holding a single file or part of a file. If

UNIT 4: HUMAN PHYSIOLOGY ASSIGNMENT TITLE: MUSCULOSKELETAL SYSTEM:j PECTORAL GIRDLE: The human appendicular skeleton is made up of bones of both the upper limbs and the lower limbs. Within the skeletal system a limb girdle can be referred to the bones which connect a limb to the axial skeleton. There is the pectoral girdle also known as shoulder girdle and the pelvic girdle also known as hip girdle which are the bony apparatus with which a limb is joined to the trunk.

Unit 2 (Computer Systems) Assignment 1 (Task 2 P2 & P3) A description of the purpose and function of an operating system. Ensuring you discuss: The difference between command line and GUI (Graphical User Interface) operating systems- Command line is a user interface, the command line is a user interface which is navigated by typing in commands prompt, as opposed by using the mouse which will perform a command for example, the root MS-DOS command line prompt is C:\>. The GUI (Graphical User Interface)

Unit 8 Analysis – System Performance NT. 1110 | System Performance The performance of a computer system is based on numerous factors. The CPU, GPU (video card processor), RAM, VRAM, and hard drives all have some impact on how well a computer system performs. With the continuous use of hard drives, fragmentation occurs. This occurs when files cannot be contiguously stored. Basically, files are broken down and scattered around the hard drive. The computer than has to provide extra work

P2-Explain the purpose of an operating system The Operating system is the most vital set of programs which runs on the computer. Its PURPOSE is to providing the very basic user interface there are no other programs or application running. The key roles of the Operating system are to recognise input from peripherals such as a mouse, keyboard, USBs, digital sketch pads and other input devices and also controls other peripherals such as printers and scanner. It also has the role of managing hardware

Digestive system P2 The Digestive system is a bodily system that converts food into energy, nutrients and cells for the repair of the body. The digestive system consists of a number of organs; the Stomach, Liver, Gallbladder, Pancreas, small Intestine, large Intestine and many more. Digestions Digestion is the process that turns food into its component chemicals. This starts off with mechanical digestion, this is the physical breakdown of big pieces of food into smaller pieces, chewing in your

The second stage is Requirement Analysis and Design. Requirement Analysis gathers the systems requirements. In this stage there's a detailed study of the business requirements of the organisation. Additional drive of this stage is to make a reasonable model of the new system. In Systems analysis the organization user also examines business procedures and records what the new scheme has to do. In the systems design stage the user interface is intended to single out the inputs, outputs and processes
