Hardware Systems
Many technologies are available to a business looking to create their own digital data. Nevertheless, some things must be well thought-out before buying equipment or software. The deciding factors of what will work best for an organization are dependent on the organization’s current software, budget, skill-level of employees, available time, available data, and amount of data in need of digitizing. Because the process of data conversion, collection, and creation is often the costliest component of applying a data storage system, the conclusion cannot be made without careful thought.
Accuracy of data input is important. What method of data input would be best for each of the following situations and explain why.
• Printed questionnaires - Keyboard
• Telephone survey – Keyboard
• Bank checks – Scanning
• Retail tags - Scanning – Bar Codes
• Long documents - Scanning
The best method of entering data is the keypad. While the rate at which information can be entered is based on the skills of the individual entering the data, it is still the most acceptable method.
Scanning is the process of translating photographs into a digital form that can be recognized by a computer. Scanners come in an assortment of configurations. The type that should be considered depends on your scanning needs and budget.
Bar codes are designed for quick and accurate data entry. Bar Codes can be printed effortlessly on many laser printers and can be attached to nearly anything, such as equipment, work orders, and machines, supply parts, and more.
Convenience and quality of output are important. Explain what method of output would be best for each of the following situations and explain why:
• Handheld computer – Wireless data transfer - the whole point of a handheld is mobility, and if you cannot be mobile with data transfer then it is a pocket post-it note.
• Color photograph – photo quality printer along with photo quality paper.
• Resume – Laser printer - High-resolution and high-definition on heavy, quality paper, for a good hands-on presentation. In today's world, a resume should also be easily scan-able and this is a reason to consider ...

...sp; Data on hard disk - This is why we defrag as often as needed. Although the data can be retrieved in any order, if related data is stored adjacently it goes faster.
• Data on CD-ROM - How fast the CD reader can read the CD and the bus can transfer the data to the CPU.
• Data on floppy disk – Speed is determined by the ability of the reader.
Computer hardware can be any part of a computer that you can touch. This includes the keyboard, monitor, mouse, floppy, hard drive, and all the pieces of electrical, physical, and mechanical components. While there are many different versions and manufactures of system components, the basic components are the same.
