Computer data storage

COMPUTER COMPONENTS The are many types and sizes of a computer. The two main sizes are: • Desktop • Portable (e.g laptops, notebooks) Computer consists of two mayor elements: HARDWARE AND SOFTWARE Hardware: Computer hardware is any components you can physically touch. Examples of hardware in a computer are the keyboard, monitor, mouse and the CPU. Hardware is directed by the software to execute any command or instruction. A combination of software and hardware form a usable computing system.

unit are as follows: Hard drive Definition- is a data storage device used for storing and retrieving digital information. Function- responsible for storing all documents and data, including files, the operating system and more. Central Processing Unit Definition- piece of hardware that carries out the instructions of a computer program. Function- performs the basic arithmetical, logical, and input/ output operations. Power Supply Definition- computers need power to function. Function- is to convert

Types of Storage Devices Physical components or materials on which data is stored are called storage media. Hardware components that read/write to storage media are called storage devices. Two main categories of storage technology used today are magnetic storage and optical storage. Primary magnetic storage o Diskettes o Hard disks (both fixed and removable) o High capacity floppy disks o Disk cartridges o Magnetic tape Primary optical storage o Compact Disk Read Only Memory (CD ROM)

Computer services are normally offered physically. Here the user of the computer can have access to the resources that the computer use. The resources includes network, storage and operating system. The term cloud computing refers to the offering of such services over the internet. Many companies offer cloud services and in turn charge for the service that they offer, while others don’t. Cyber-forensic investigations have been affected by cloud computing since the beginning of the cloud. Computer

Computer memory (an information storage device, a storage device) is a part of a computer, a physical device or a data storage medium used in calculations for a particular time. Memory, like the CPU, is an unchanged part of the computer since the 1940s. Memory in computing devices has a hierarchical structure and usually involves the use of multiple memory devices having different characteristics. Computer memory provides support for one of the functions of a modern computer, the ability to store

systems is the structure that allows you to communicate with computer hardware in a communicating way , without an operating system you wouldn’t be able to tell the computer to do anything and it won’t have any instructions to follow. Purpose of an operating system: Operating system controls the hardware and software properties of the system in a computer these properties include things like processer, memory and disk space. Computers must have an operating system to run other programs also an

The purpose of this technical document is to provide guidance to customize a personal computer. It is targeted for those individuals with a minimal knowledge about components of a computer but also extends up to students, faculties, and staffs who relies on their PCs to perform their everyday tasks. This design report is inspired by the fact that most of the computers available in the market today are not a perfect fit to a specific user’s application and are very expensive. Therefore, this document

Explain how software utilities can improve the performance of computer systems The computer system comes with many different kind of software utilities which help the user to maintain and improve the computer system performance. Software utilities can do many different things and offers many different features and tools that help the user to improve system performance, such as clearing junk files from the storage device, update device drivers, scan for viruses or spyware, optimise memory, defrag

PROJECT PROPOSAL Moving from Structured to non-Structured Data PROJECT ADVISOR PROJECT TEAM: ABSTRACT The promise of data-driven decision-making is now being recognized broadly, and there is growing enthusiasm for the notion of ``Big Data.’’ While the promise of Big Data is real -- for example, it is estimated that Google alone contributed 54 billion dollars to the US economy in 2009 -- there is currently a wide gap between its potential and its realization. Heterogeneity, scale
