Hardware and Software requirements

All ICT systems require Hardware and software in order to function. For the ICT system I am going to produce for a sole trader, the following requirements are essential for this

Hardware

  • A CD-RW or DVD-RW is needed to save/backup large amounts of data in the event of corruption. It works by using microscopic bumps to store data. The surface of the CD disc is a mirror, and the bumps disrupt the mirror's perfect surface. The laser that reads the CD or DVD can detect the difference between a perfect mirror and an imperfection caused by. By identifying the bumps as a "1," and no bump as a "0," it is easy to store digital information on a CD or DVD. The bumps on a CD are molded into the plastic when it is produced, so they are permanent Files can be accessed on other computers and copied. Alternatives to this device are portable Flash drives, zip disc the old method of tapes and Floppy discs.

  • FDD to save/back up small files and to add small programs or updates to programs.

  • A fast CD-rom can be used to add further programs and utilities to enable better user accessibility. It can also be used to update existing software.

  • At least 40GB of hard drive to support programs and to save files.

  • A barcode scanner to scan UPC barcodes to identify the price of the product, a handheld barcode scanner for larger items.

  • An inkjet or laser printer to print invoices, statements, reports, price tags and bar code labels.

  • An automatic cash drawer to store cash, cheques, vouchers, receipts, and credit receipts.

  • A portable stock counter would be useful to make stock intake more successful and efficient.

  • A POS receipt printer to give the customer a record of what has been purchased and if needed return the product if there has been a defect.

  • A CCTV close circuit tv system is very important because it ensures in the event of burglary or an assault on an employee.

  • Electronic Weighing scales for loose items such as tomatoes

Software

 

  • A program that can produce spreadsheets is essential to us. It also need to be very easy to produce a spread sheet and automatically calculate equations

  • A Word processing program needs to be used to produces business documents such as: Fax sheets and letterheads. An advantage of using such a program is that documents can be spell checked

  • A database management system can be used to store large amounts of data such as details of products, stock intake, amount of profit using a program like this is useful because the information can be easily retrieved, modified or more data added.

  • A powerful compuer operating system is essential because most programs need a lot of memory space. It also needs to be user friendly, so when a new employee joins it is easy to adapt to.
