Computer hardware and software
Computer software refers to a collection of procedures, computer programs and codes that perform different functions on a computer system. Software systems are often classified into system software, programming software, and application software. Any physical device used in or with a computer is referred to as computer hardware. A computer display monitor, a CD-ROM and a printer are all examples of hardware.
Functions of computer hardware
The following are the functions of different computer hardware:
Internal system unit components
A processer, also known as the central processing unit (CPU), enables the operating system and operating software run on a system, by executing a set of instructions (Clements, 2006). A motherboard holds the processor and links internal components, such as the random access memory (RAM), together using communication buses. Basic input/output system (BIOS) is responsible for linking computer software and hardware (Clements, 2006). It ensures hardware components perform their functions and turns off processes in the correct way. A power supply unit (PSU) is used to power the components in a computer system while the universal serial bus (USB) and serial enable it to communicate with external devices.
Internal memory components
Internal memory components include the RAM, ROM and cache. Data is written and...
Comparison of Product Suitability The Inspiron Mini 10 (1018) Netbook (http://www.dell.com/us/p/inspiron-mini1018/pd) meets all of my needs for a portable computer as described. However, for full computer functions that include a 40 GB hard-drive, 1.86 Gigahertz microprocessor speed, 512 MB RAM, with Windows XP Pro Business Suite, CDRW and DVD burner, I use an IBM Thinkpad Model-Year 2005 T-43 (http://www.amazon.com/Thinkpad-T43-1-86GHz-Laptop-Notebook/dp/B000979258/ref=sr_1_1?s=electronics&ie=UTF8&qid=1287825031&sr=1-1). The full-feature capabilities of this IBM Thinkpad are equivalent to a basic desktop computer
Computer Hardware Industry: Marketing and Advertising Strategies Within this research paper, an overview will be provided of marketing and advertising strategies utilized within the computer hardware industry. For the purposes of accomplishing this aim, the strategies used by Gateway, Dell, and Hewlett Packard will be examined. As each company is analyzed, comparisons and contrasts will be made with strategies used by the competitors. Gateway According to Fikes (2003), Gateway Inc., once famous
While there are problems with using two cards at the same time, they can be worked out with study and creativity. In fact, there are ways to use two AGP slots on the same computer, so nothing can be ruled out when it comes to combining cards and slots (Weinand, 2004). In conclusion, graphics cards have evolved from simple chips that displayed nothing more than text into graphic wonders that
Computer Forensic Tools: The use of computers in homes, schools, offices, and other places has increased in the past few years due to technological developments. As computers have become important components of modern communication, their increased use has also led to the emergence of computer crimes. Computer crimes basically involve the use of a computer system to carry out an illegal activity. In attempts to lessen the frequency and impact of

Subtopic 6: Job management and protection; include a serious discussion of security aspects The most commonly leveled criticism of operating systems is the inherent lack of security they have (Funell, 2010). Defining operating systems to have partitioned memory is just the start, as Microsoft learned with their Windows NT platform. Dedicated memory partitions by user account can be hacked and have been (Funell, 2010). The need for greater levels of user
