Laptop Computers, Modems, Printers: In hotels these electronic equipments are frequently used for various purposes for in-house data managing as well as a facility for the guests to use. In-house use may be for guest registration in front office, inventory management in housekeeping and kitchens and administrative staff related works with a LAN Network (Local Area Network)

Computer and Peripherals Maintenance:

Computer Usage Tips Þ Never, turn your computer off with the power      switch until Windows has shut down. Þ It is recommend to use an UPS. Þ Take Backup data always. Þ Run Scandisk and De-fragment at least once a month Þ Never unplug peripherals from the computer when it is      powered up. Þ Do keep at least 300 MBs of your C: drive free for      Windows to use. Þ Do not let a lot of programs load up when you start your      computer Þ Do use an anti-virus checker regularly (preferably in auto      mode) Þ If you use a high speed Internet connection, you need a      firewall program. Þ Keep track of the software disks you receive with your      computer Þ Make sure Windows Update is set to Automatically      Update your computer. Þ Keep computer, modem, printer away from moisture and      heat

Computer cleaning: Computer cleaning is the practice of physically cleaning the interior, and exterior, of a computer including the removal of dust and debris from cooling fans, power supplies, and hardware components.

Backup: Important data stored on computers may be copied and archived securely so that, in the event, of failure, the data and systems may be reconstructed. When major maintenance such as patching is performed, a backup is recommended as the first step in case the update fails and reversion is required.

Disk maintenance:  Disk storage, such as your hard drive, fills up with unwanted files over time. Disk cleanup may be performed as regular maintenance to remove these. Files may become fragmented and so slow the performance of the computer. Disk defragmentation may be performed to combine these fragments and so improve performance.

Dust and other cruft may accumulate as a result of air cooling. If filters are used to prevent this then they will need regular service and changes. If the cooling system is not filtered then regular Computer cleaning may be required to prevent short circuits and overheating.

Operating systems files such as the Windows registry may require maintenance. A utility such as a registry cleaner may be used for this.

Service intervals: Depending on your environment computers should be serviced at least once per quarter, though monthly service is optimal. This will ensure your computers run at their peak performance.

Software updates: Software packages and operating systems may require regular updates to correct software bugs and address security weaknesses. An automated or semi-automated program such as Windows update may be used for this.

Projection screens: In modern day environment, hotels provide facilities for corporate companies to hold business meetings, conferences, sales promotions and other functions. For this purpose the auditoriums are equipped with these modern equipments to facilitate the guests in their activities.

Overhead projector is a variant of slide projector that is used to display images to an audience. An overhead projector is a very basic but reliable form of projector. The overhead projector displays images onto a screen or wall. It consists of a large box containing a cooling fan and an extremely bright light, with a long arm extended above it. At the end of the arm is a mirror that catches and redirects the light towards the screen.

LCD data/video projectors:  An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern analog of the slide projector or overhead projector. To display images, LCD (liquid crystal display) projectors typically send light from a Metal halide lamp through a prism or series of dichroic filters that separates light to three poly silicon panels – one each for the red, green, and blue components of the video signal. As polarized light passes through the panels (combination of polarizer, LCD panel and analyzer), individual pixels can be opened to allow light to pass or closed to block the light. The combination of open and closed pixels can produce a wide range of colors and shades in the projected image. Metal Halide lamps are used because they output an ideal colour temperature and a broad spectrum of colour. These lamps also have the ability to produce an extremely large amount of light within a small area: current projectors average about 2,000-15,000 ANSI lumens. Other technologies, such as DLP (Digital Light Processing) are also becoming more popular in modestly priced video projection.

Microphones, Amplifiers, Speakers: These are also essential equipment in conference halls, meeting rooms, auditoriums as well as for announcing arrival / departure of valet parking for guests.

VCR / DVD Players: These equipments are needed in hotels for the facility of guests and other in-house training purposes.

CCTV: Closed Circuit Television Cameras are used in hotels in various areas for security monitoring, surveillance and early information of emergency situations. These cameras are strategically located to capture images of sensitive areas and send them to a central control room for display on television screens and also for recording purposes.

Sensors: A sensor (also called detector) is a device that measures a physical quantity and converts it into a signal that can be read by an observer or by an instrument. Sensors may be used for sensing heat, smoke, light interference, touch, vibration, temperature, water flow, over-current etc.  For example, a mercury-in-glass thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter. For accuracy, most sensors are calibrated against known standards. Sensors are used in everyday objects such as touch-sensitive elevator buttons (tactile sensor) and lamps which dim or brighten by touching the base. There are also innumerable applications for sensors of which most people are never aware. Applications include cars, machines, aerospace, medicine, manufacturing and robotics.
