21. Introduction to Computers: CPU Central Processing Unit– The heart of the computer where data is processed. Click on this Video Link: History of Intel CPU. A CPU consists of control and arithmetic/logic units and primary storage. Primary Storageconsists of random-access memory (RAM) and read-only memory (ROM). RAM is measured in bytes. Most computers come equipped with at least 512,000,000 bytes (512 MB). The number of bytes required depends on how much space the program and data occupy. Speed is measured in gigahertz (GHz) or million instructions per seconds (MIPS). It is important to make sure that the CPU has enough processing power to handle all system requests. The speed at which data travels is affected by the data busor size of the data path. A 64-bit bus can transfer data more quickly than 32-bit bus. The latest development is the multi-core CPU, which enables two (dual-core) or four (quad-core) CPUs to be integrated on a single processor chip. More RAM enables a program to run faster since more of it can be loaded into RAM. Windows 7requires at least 1 Gigabyte of RAM for it to run comfortably.

22. Introduction to Computers: Storage Devices Hard Disk- Most of the data processed by a computer resides in permanent or nonvolatile storage called a hard disk. The size of the hard disk depends on program and data space requirements. Typical capacity ranges from 80 gigabytes to over one trillion bytes or one terabyte (1 TB). Click on this Video Link: Look at the inside of a hard drive. USB Flash Drive- A miniature mobile device (16 MB to 4 GB) that is used to transfer data between a desktop computer and a notebook computer, or for personal backup needs. Magnetic Tape- Used for storing and backing up large amounts of data (up to 800 gigabytes) quickly and cost effectively. Optical Storage– Used an alternative to magnetic storage. Data is written to optical media (e.g., CD , DVD) with a laser for archival or backup purposes. Optical discs are more durable than tapes but slower than typical hard drive speeds and offer lower storage capacities. © 2008 Jupiter Images Corporation

23. Introduction to Computers: Output Devices Printers - Key factors to consider when purchasing a printer include print resolution (DPI) and speed (PPM), color, wireless and remote printing capabilities, paper handling, life expectancy, and cost. Two basic types of printers are impact (e.g., dot matrixfor food orders in the kitchen) and non-impact (e.g., thermal for producing restaurant checks, inkjet for generating business documents, and laser for printing guest folios and registration cards). Click on this Video Link: Dot matrix printer used in the kitchen. Monitors - Key factors to consider when purchasing a monitor include resolution (800 by 600 to 2560 by 1600 pixels), dot pitch (.26mm), refresh rate (72 Hz or screens per minute), ergonomics (adjustment controls), and color. Configuring the information system for optimal performance. The two basic types of monitors are the flat panel monitor(e.g., LCD) and the CRT monitor. LCD monitors are popular because of their thin design and superior performance. Click on this Video Link: Digital menu.

29. Advantages of Computerizing Information Processing Improved labor productivity. Eliminates repetitive clerical tasks and redundant data entry and increases the span of control (e.g., Taco Bell increased the span of control from one supervisor for five restaurants to one for 30 through technology). Enhanced decision-making capability. Provides access to timely, relevant information. For example, Donato’s Pizza restaurant uses a Business Intelligence System (BIS) or Decision Support System for consolidating data from different systems to reveal real-time data on customer frequency, order trends, and coupon performance. Click on this Video Link: “The evolving information age.” Reducing operating costs. Emailing reservation confirmations, for example, saves paper and lowers mailing expenses. Increased information accuracy. A computer reduces the number of times data is handled by employees. One study revealed that handwritten restaurant checks, for example, were inaccurate 16% of the time.

30. Advantages of Computerizing Information Processing Increased revenues. Ensures that all sales are captured and recorded properly and enables the automatic execution of revenue enhancement strategies based on an evaluation of product pricing and cost in relationship to facility capacity (e.g., If occupancy in the group discount class exceeds X percent with Y days before arrival, then move all group discounts to the rack rate class). Greater customer satisfaction and loyalty. Computers enable employees to more efficient and responsive to customer needs. For example, wireless order taking enables servers to provide faster service. Computers are used to collect data about customer satisfaction. For example, European-based Accor sends follow-up e-mails to guests immediately after a stay inviting them to take an online survey

31. Advantages of Computerizing Information Processing Greater customer satisfaction and loyalty Feedback is also obtained from Consumer Generated Media, such as blogs, discussion boards., hotel and travel review sites, social networks, etc. Click on this Video Link: Strategic Internet marketing and social media and computing. A Facebook application was developed by Renaissance Hotels entitled the “Renaissance Cocktail Mixer. The app lets users send and receive house specialties. After installing the app, virtual dice are rolled to select a cocktail, then an action is selected—toast, shake, pour, mix, etc.—before finally selecting which Facebook friend to send the virtual drink. That person then displays the drink on his or her Facebook profile page. Improved controls. Automated systems make it possible to collect money earlier and to spend it more intelligently. For example, notices on past due accounts can be sent out more quickly.

32. Technology and Information The organization of information affects its usefulness. There are several ways to organize information: category, time, location , alphabet, and continuum. Category . Overtime hours broken down by job position pinpoints where corrective action is needed. Time. Recording the number of meals served per hour assists in labor scheduling. Location. Performance can be tracked for each property in a hotel chain. For example, an executive vice president of one hotel chain lowered the labor cost percentage by 10% by sending each GM a report that contained the labor cost percentage for each property in the chain, which incited healthy competition to top the best performance.
