Presence of Computers

Computers are everywhere. Be it a home, school, hospital, banks, offices, post offices, grocery shops, medicine shops or theatres, we can see the presence of computers evenly. The use of computers has become mandatory to make the works easier and effective. People face several technical problems related to computers, its uses and application in their work and at homes. Along with the wide use of computers, occurrence of problems has also increased.

Presence of Computers at Home

Computers and Internet is a part of every home in current modern world. It has taken place as an important and integral electronic Item. The necessities of computers are well known for every member of the family, kids want them for playing different games, and youngsters need a computer and internet for surfing or download music and gadgets of their interest, mature members of home need computer to check official mails or for simply being in touch with relatives, friends and other people. Even housewives use computers for learning new recipes, home decoration tips, and various other skills.

Presence of Computers at Offices

Computers are essential need of every office to perform the work in effective, timely and organized manner. At some places we cannot imagine an office without a computer like Banks, Railway Station, Airports, and Departmental Stores. The work volume and need for storage of data for future use is very important in these cases. The only option is to rely on computers to solve all the required purposes. In brief, we can say Computers are a part of almost every business installations.

Problems Scenario

Computers are electronic machines and like all other machines, they are prone to creating problems. The cause f problem can be anything, may be excess utilization of resource, mishandling, power problems, virus attacks or any physical issues. To solve these problems, larger installations like software companies, BPO organizations, banks, and government offices usually have an IT troubleshooting cell, taking care of all the problems.

But, it’s not possible for small businesses or home users to hire a fulltime IT troubleshooter for these problems. To solve their day-by-day problems, small businesses and home users contact nearest IT troubleshooting services providers. These troubleshooters do excellent job of helping out home users, and small offices to help them work in easier and effective way without being worried of future problems in their computers and internet connection.

Many current supply chain RFID (Radio Frequency Identification) operations involve tracking pallets, containers and cases. Much of these activities are driven by compliance with customer initiative. It is difficult to manufacturers and their distribution wings to get a positive financial return on their RFID investments. RFID has been proven time and again to provide strong ROI when it is combined with improved business processes that reduce labor and prevent errors. A combination of mobile and fixed-position RFID readers support these operations and helps deliver these benefits.

Four Ways To Improve Operations And ROI Using Mobile RFID
The integrated mobile RFID system can improve the ROI in four primary ways. They are:

• Reduced Capital Expenditures: Though RFID is used either for basic compliances or for extensive applications it can save huge execution costs than that of traditional configuration. The organizations that receive the RFID tagged cases and pallets will install fixed position RFID readers at dock doors to record tagged shipments. The second option is to install readers at a position of dock doors and schedule adequate time and efforts on them, so that tagged shipments are processed at RFID-enabled locations.

• Increased Asset Utilization: When RFID applications are moved from dock, there will be a better asset utilization and ROI. RFID can process tagged cartons and pallets wherever goods are handled. A mobile reader uses them in multiple ways throughout the facility, which provides superior asset utilization. The RFID system has an optimal real time location service (RTLS) features to further improve asset utilization, productivity and trend reporting. This includes, asset location and management, security, dynamic routing, productivity reporting and more. These features improve the picking and putaway operations and reduce the losses caused by automatically recording items in unmarked locations.

• Scalability: As the mobile RFID systems are used throughout the facility, new RFID readers may not buy new updated or expanded applications. It processes for picking, replenishment, shipment verification and inventory transfers can be completed with the same mobile equipment used at the dock doors. The inherent scalability of mobile systems takes much of the incremental cost out of expanded RFID operations. It introduces additional labor-saving applications that leverage the initial investment and improve overall ROI.

• Labor Savings and Process Improvement: The RFID system is proven to reduce the costly inventory handling and shipping errors and reduces associated costs. The process improves the productivity and makes it possible to track the goods in locations and environments. RFID increases tracking and improves visibility, where as bar code scanning is labor intensive. It helps in preventing shortages, over stocking, shipping errors and provides several other benefits.

The above information makes you know how the mobile RFID systems improve the operations and ROI of your business.

Okay let’s go!

Cache: Cache is another type of memory kindred to RAM. The computer uses cache to quickly move data between the RAM and the CPU.

CD-ROM Drive: Most new computers now come with a CD-ROM drive as standard equipment. A CD-ROM drive reads data from a disc. These CDs look like a music CD, but hold data instead of music. CD-ROMs also contain games, dictionaries, recipe files, and lots of other things that you can load onto your computer.

CPU: The CPU, or central processing unit, is the brains of the computer. Most new Windows based programs use a Pentium processor or a AMD Athlon XP. New Macs use a different type of CPU called Power PC.

Disk Drive:Virtually all computers come with a disk drive that can read and save information on portable diskettes, also called floppy disks. You can use floppy disks to save information or to load new software onto your computer.

Hard Drive: The hard drive is also called the hard disk. You will probably never see it because it is nestled inside your computer. It’s the computer’s electronic filling cabinet, and it stores the computer’s operating system, files, programs and documents.

Keyboard: Just like a typewriter keyboard, this device is the primary way of inputting data into the computer programs.

Megahertz (MHz): This is the clock speed of the microprocessor. The higher the number, the quicker the information is processed. MHz relates to how many millions of instructions can be processed per second.

Memory:This is the circuitry or device that holds information in an electrical or magnetic form. There is read-only memory (ROM), which is information primarily stored on a disk, and random-access memory (RAM), which is chip-based storage inside the computer. Memory is typically measured in megabytes (MBs).

Modem:This mechanism connects a computer to a phone line so information can be sent from one computer to another or the user can access an on-line service or the Internet. In view of the popularity of the Internet, a modem is now considered basic equipment and comes on practically all-new computers. Most modems come with fax capabilities.

Monitor: An output device that allows you to see what you are doing (it is what you are looking into right now to see this). Most computers come with 14 or 15-inch monitors. This size is good for most people’s needs. Larger 17 or 21-inch monitors also are available, but may cost more. Myself, I prefer the 17-inch.

Motherboard:The motherboard is the circuit board that everything in the computer plugs into. The CPU, RAM and cache all plug into the motherboard.

Mouse: The mouse is another input device that makes getting around in your computer easier. It is a handheld object that is good for doing tasks such as moving and pointing to objects on the screen, and can replace the function and control keys of the keyboard. (If you need a lesson on how the mouse works and how to use it click here for a tutorial.)

Printer: A printer is an essential part of the computer if you want a hard copy of your work. There are four types of printers on the market: dot matrix, inkjet, bubble jet and laser. The dot matrix is the most basic. Most inkjets and bubble jets can print color and graphics, and a laser printer offers the best resolution at the highest speed.

RAM:Computers save data in two ways: on the hard drive and in random access memory or internal memory. New computer buyers should look for models with at least 16 MBs of RAM (or more, depending on what types of programs you will be running). Make sure that the computer can be upgraded.

Scanner:A scanner is a useful accessory to have if you are working with lots of artwork or photos. This device can copy written documents, pictures or photographs directly into your computer. There are three types of scanners: handheld, hopper-feed and flatbed.

Sound Card: This device allows your computer to reproduce music, sounds and voices. Make sure you have a sound card if you are planning to play multimedia games.

Video Card: The video card is the part of the computer that sends the images to the monitor.

Well there you have it, a quick course on computer terms. I hope it has helped to guide you in your purchase of a new computer; or to help you with the one you have.

The purpose of this article is to show you the available options for termination a fiber optic cable installation project. I will compare the pros and cons of different termination approaches.

Fiber optic cable termination can be divided into two major groups: factory termination and field termination.

Field technicians face important trade-offs in deciding which approach to choose. For tighter loss budget, the best approach is factory terminated cables since it is much easier to achieve loss loss and high quality connector terminations in a controlled factory environment. On the other hand, field terminations provide far more flexibility in meeting system requirements.

Pros of factory termination

1. The factory has to guarantee the quality. Fiber optic manufacturers have highly trained technicians and high quality equipment for the job. Factory technicians usually are expert on fiber connector polishing and they produce thousands of fiber optic patch cords and fiber pigtails on a daily basis.

2. Factory termination provides the lowest cost. Since factories produce mass quantity of fiber patch cords, they have reduced the cost to the lowest possible point. This is the most economic choice.

Cons of factory termination

Factory termination doesn’t provide as much flexibility as field termination. You have to write down the list of fiber lengths and quantities and you have to make sure that you have enough spare length of cable for each termination.

Pros of field termination

1. Field termination provides the best flexibility in meeting system requirements. You can just pull the fiber cables and terminate them later.

2. You can do on-the-spot repairs wherever there is a defective fiber link. This is the biggest advantage of doing the termination yourself.

Cons of field termination

1. High cost. You need some polishing tools and supplies. Field termination quality are OK for multimode applications, but for single mode applications, you’d better leave that to factory termination.

2. The field termination technician must be highly skilled. He would have to practice a lot offline before doing the real work. A bad termination can cost you both time and money.

OK. You must already have a pretty clear idea on the choices for fiber cable installation now. Let’s examine in more details on the available options for each category.

Factory termination choices:

1. Factory pre-terminated cables

For this type of job, you provide a list of cable types, lengths and quantities to the factory. The factory will deliver each pre-terminated cable on a reel. You just need to pull these cables through duct carefully with a cable netting to protect the connectors.

2. Factory pre-terminated pigtails and splicing (fusion splicing or mechanical splicing)

This is a intermediate approach. You order cable segments with factory-mounted connectors on one end only. You need to order some fiber pigtails (fiber cables with only one connector mounted) and then splice the pigtail to the unterminated end of the cable. This is a quick and easy approach. However, it requires that you already have the fusion splicers (which could cost you tens of thousands of dollars). Or you would have to choose the less reliable mechanical splicing.

Field Termination Choices:

1. Field installation of epoxy and polish connectors

Lots of experience technicians still prefer this way since it provides the best flexibility and the lowest possible cost. Epoxy and polish connectors are the same as used by factories. You pull the fiber first, and then terminate the fiber on the site. This involves fiber optic epoxy, high temperature curing oven, scribe tools, polishing films and fiber optic inspection microscopes. This approach needs you already have a termination kit that includes these items.

2. Field installation of quick termination connectors

Quick termination connectors are a god bless for emergency repairs. This type of connector functions like a fiber optic pigtail. It is pre-polished in the factory. It has a fiber stub in the connector body. You just need to cleave your fiber, insert it into the connector body, and lock it per the connector manufacturer’s instruction. However, it doesn’t provide as much long term reliability as the epoxy and polish connectors. Also, quick termination connectors are much more expensive then standard epoxy and polish connectors.
