Software:
Computer instructions or data. Anything that can be stored electronically is software. The storage devices and display devices are hardware. (Web 2)
Operation System:
An operating system, or OS, is a software program that enables the computer hardware to communicate and operate with the computer software. (web 3)
Application software:
Application software is a subclass of computer software that employs the capabilities of a computer directly and thoroughly to a task that the user wishes to perform. (Web 4)
Memory:
Which consists of secondary storage devices such as disk - hard disc or some other kind of disc– that can store data and programs outside of the computer itself? These devices supplement memory or primary storage, which can store the data and programs only for a while. Magnetic tape, tape drive, usually used for backup purposes as it is inexpensive.(Web 5)

The processor:
(CPU), has electronic circuitry that manipulates input data into the information people want. The CPU actually executes the computer instructions. The brain runs the show inside the PC. (web 6)
III-Theoretical Background
Copyrighted and costs more than shareware. Word Processing – Memos, letters, documents etc. (web 7)
More than word processing, brochures, books, magazines, newspapers rely on desktop publishing. (Web 8)
- Electronic Spreadsheets
- Database Management
-
Personal Information Managers: Software that keeps track of all the activities of busy life. (Web 9)
- Computers and People
- Users
- Computer People – MIS, CIS, CS , IS or IT
- Data Entry Operators
- Computer Operators
- Librarians
- Systems analysts
- Network manager
- Operating system is a set of programs that lies between applications software and the Hardware.
- System software is all programs related to coordinating computer operations
- Kernel – the most important part of OS, managed by kernel, which resides in memory
- Booting – The process of loading the OS into memory
Windows Overview (web 10)
- Operating Environment – another layer added to MS-DOS
- Windows 3.1 – only 8 characters for file names
- Windows 95 – Up to 255 characters, icons, menus, pull-down menus, pop-up menus, Plug and Play, OLE
- Windows 95 – Up to 255 characters, icons, menus, pull-down menus, pop-up menus, Plug and Play, OLE
- Windows 98 and Me – Internet browsing capabilities, hardware support, support for multigigabyte disk drives, TV viewer and broadcast facility, Wizards, Multimedia support, Reliability features, Home network support
- Windows NT – New Technology, meant mostly for corporate, networked environments.
- Windows 2000 – is the final generation of NT series. Windows 2000 professional and Windows 2000 server.
- Windows XP Professional and Home (Web 11)
- Latest generation of Windows – Many features have been improved
- Windows CE (Consumer Electronics) is a Windows-based modular OS designed for embedded systems
- Embedded systems are computing devices that are integrated into other products
- Memory Management is the process of allocating memory to programs and keeping the programs in memory separate from another.(web 12)
- Foreground – A memory area for programs that have higher priority and therefore receive more CPU time. Interactive programs use this memory area.
-
Registers are special-purpose, high-speed, temporary storage areas for instructions or data.
- They are not part of memory; rather, they are special additional storage locations located within in the CPU itself that offer the advantage of speed.
- Registers work under the direction of the control unit to accept, hold, and transfer instructions or data and perform arithmetic or logical comparisons at high speed.
Intel produces Celeron, Xeon and Itanium for workstations and network servers
RAM – Random Access Memory
- DIMM – Dual in-line Memory Module, double contacts allowing faster data transfer
Microprocessor speeds are determined by their clock speed and are usually expressed in gigahertz (GHz), billions of machine cycles per second.
Another measure of computer speed is MIPS, which stands for one million instructions per second.
A third measure is the megaflop, which stands for one million floating-point operations per second.
- Touch screens enable the user to input information by pointing to locations on the screen with a finger. Some screens use a light pen as the input device, enabling more precise pointing
The use of special equipment to collect data at its source as a by-product of the activity that generates the data, and then send it directly to the computer. E.g. supermarket barcode
Scanner or optical scanner can convert text or even a drawing or photograph into computer-recognisable form by using optical recognition, a system that uses a light beam to scan output data and convert it into electrical signals that are sent to the computer for processing.
- A bar code reader is a photoelectric scanner used to input bar codes.
Hard Disks
- A hard disk is a rigid platter coated with magnetic oxide that can be magnetised to represent data.
- Several platters can be assembled into a disk pack
- Disk drive is a device that enables data to be read from or written to a disk
- Access arm is a mechanism for reading or writing data to a disk; it moves a read/write head into position over a particularlocation
Optical Disk Storage
- Optical Disk technology uses a laser beam to enter data as spots on the disk surface. To read the data, he laser scans the disk and a lens picks up different light reflections from the various spots.
- Read-only Media, Write Once Read Many (WORM) media
Compact Disks
- CD technology is an optical technology that uses the same media used for audio CDs. Types os CDs: CD-ROM, CD-R (Recordable), CD-RW (Rewritable)
IV -Recommendation
Minimum System Requirements

Driver
CD-ROM or DVD drive
Image
1024x768 or higher resolution monitor
Operating system
Microsoft Windows XP or later operating system.
Customized invoices, sales orders, bids, customers return the bills, statements and purchase orders to create a Microsoft Office Word, Excel or later is required.
To use certain features will require additional Microsoft technologies
Documents in PDF or XPS format to send as e-mail attachments in Word 2007 or Outlook 2007 is required.
To use Excel reports in Analysis Tools for Excel 2003 or later is required.
Actual requirements and product functionality to the system configuration and may vary depending on your operating system.
There is a lot of computer types in the world, that means it has a lot of choose and technology grown up every day, there is no chance to catch up technology.

As we discus in this report IT has many aspects this includes Hardware and Software, which is important for the successful running of any business. It is important to pick the right computer that will help your business growth. This report recommends Packard Bell B2217 it is cheapest computer and report safes money. In addition, that computer has Intel Celeron Dual-Core processor it is enough for the restaurant and it will be more than powerful. It has also 1 GB Hard Drive and 160 hard drives very good for the restaurant. It has also Dual Layer DVD Rewriters there is good also this report recommend is such a good for the restaurant workers.
This report compared for three computers that it has compared with Packard Bell B2217 and it also POS computer.
V-Conclusion
It will provide system that helps retailers, traders and restaurant managements to make accounting activities. However, this needs to support the system that will be used in particular business sections. All through the different operating systems, suitable of the equipment and component will be chosen. It is necessary to find out the right selection when we want to have computer systems in the workplaces. Because of the every information and accounting, functioned activities provided individually service to the places. It will be focused on advising the most effective functional system.
