wireless communication is one of the fastest growing technologies. The demand for connecting devices without the use of cables is increasing everywhere. wireless lans can be found on college campuses, in office buildings, and in many public areas. wifi (wireless fidelity) has brought a new dimension in the field of wireless networking. The transmission of data is done through the radio waves in the free space. It cuts down the cost of laying down the cables for network connections. The systems which are wifi enabled are mobile and can be used anywhere in the range of the network.

wireless router.

router is a connecting device, which receives the data from the source and route the data to its destination. wireless routers refer to the devices in the wireless network, which receives the signal from a source and rout the signal to its destination by examining its ssid. routers are generally used to interconnect two networks.

A wireless card.

Some systems which do not have in built wifi devices so they need an external interface card which connects the wifi device (a transmitting device) to the system. These cards can be connected to the pci slot of the mother board . Also in order to receive the wifi signal from devices our system should be equipped with a receiver. Nowadays receivers that can be connected through usb are also available.

Hence we see that wifi has numerous advantages. Nowadays wifi connections can be found on college campuses, in office buildings, in many public areas. If we consider the present world, we find that the demands for the wifi connections are increasing. people are beginning to appreciate the advanced features wifi network provides to the user. Due to its increasing demand the scope of the wifi network is also on the rise. Here we highlight the major benefits of installing a wifi network.

Firstly it cut down the cost of laying down the cable for network connection.Secondly with no wires attached it is possible that the sender node can be mobile.Thirdly the equipments required to fully establishing the wifi network anywhere is relatively cheap. So the cost incurred in establishing the wireless wifi connection is cheaper and also very easy to install. wifi established in small place do not even need the wireless routers.

Lastly it is also possible for the user to have a better speed of internet connection by using wifi network. Since the bandwidth provided by wireless cutwork is large connection speed between two nodes is faster. It is also faster to transmit data between two devices connected through wifi.

computer HARDWARE BASICS

MICROPROCESSOR:

Microprocessor is the brain of any computer. It controls all activities inside the computer. Basically it performs 2 types of operations - arithmetic & logical operation (internally), read & write (externally). Read /write operations are performed on 2 types of devices - I/O and memory devices. It uses the address bus to select any location on these devices, sends a read/write signal over the control bus and then the information over the data bus.

MEMORY devices:

The CPU stores all information in the computers memory. There are two memory types - RAM & ROM

RAM (Random access Memory):

This volatile type is a read & write memory device. This loses its contents when power is shut off.

The types of RAM are

DRAM (Dynamic ram) is similar to a capacitor, as it tends to lose its contents and hence requires to be refreshed. This is the computer RAM.

SRAM (Static ram) Is faster than Dram and doesnt require to be refreshed. This is costly and hence only a limited amount is used as CACHE memory in the computer.

ROM (Read only memory):

ROM can be programmed using a programmer and then it acts as a read only device. This device is used as the textbook for the CPU in the computer and is called ROM BIOS. It stores all the basic information of programming the devices present inside the system as well as the POST (Power On Self Test) sequence. AMIBIOS and AWARD BIOS are the most common ROM BIOS.

The types of ROM are

PROM (Programmable Read Only Memory)

EPROM (Erasable & Programmable Read Only Memory)

FLASH ROM

EEPROM (Electrically EPROM)

EAPROM (Electrically Alterable ROM)

I/O devices:

Apart from passive memory devices, there are certain controllers in the system, which assist the CPU in performing various operations. These are referred to as I/O devices. These devices include Interrupt controller, Timer, Ports, DMA controller, Floppy Drive controller, CRT controller etc.

BUSES & EXPANSION SLOTS:

These are the means through which communication between various devices of the computer takes place and the types are as mentioned below.

ISA (Industry Standard Architecture):

ISA bus consists of a 24-bit address bus and the 16-bit data bus. ISA can support 8MHZ clock speed.

MCA bus (Micro Channel Architecture):

MCA bus is available either in 16 bit or 32 bit versions. It was developed in a new line of computers called the PS/2 (personal system 2). The clock speed is slightly faster (10MHZ instead of 8MHZ).

EISA bus:

EISA has a 32-bit Address and data bus and 10MHZ CLK speed.

VL BUS/VESA LOCAL bus:

It is a 32-bit bus which was positioned local to the CPU and hence its name. Therefore it could support high bus speeds (that of the CPU).

pci bus:

pci has many benefits over other bus types. First of all, it supports 64 bit and 32-bit data paths. So it can be used both for 486 and Pentium based systems. pci can run up to 33MHZ speed and has the advantage of being isolated from the CPU. intel developed this bus.

pcmcia: (PC Memory card International Association):

The pcmcia was first designed for expanding the memory in small, handled computers. PCMICIAS bus width is only 16 bits, but a 32-bit version is on its way. There are three types of cards namely

Type 1 (3.3 m thick)- used for memory card.

Type 2 (5 mm thick)- used for modem and lan adapter.

Type 3 (10.5 mm0 thick) - used for most common applications like PC hard disk cards.

add ON cards:

These are cards plugged on to the main board, the mother board (The one that houses the CPU & RAM/ROM Bios). Each performs specific functions of interfacing the Motherboard to peripheral device like mouse, monitor etc. Some add-ons are discussed below.

DISPLAY adapter:

These interface the motherboard with the monitor and there are several types of cards. The variations are in resolution, no. Of colors supported and speed.

CGA (Color Graphics Adapter)

640 X 200 pixels

MDA (Mono Display Adapter):

80 characters wide 25 lines long

EGA (Enhanced Graphics Adapter):

640 X 350 mode

VGA (Video Graphics Adapter):

Advanced versions of SVGA/TVGA which start from a resolution of 640 X 480 pixel

AGP (Accelerated Graphics Port):

Introduced in the celeron/P II based systems, this caters to the demanding multimedia applications with its high performance.

IDE I/O card:

Supports the following functions.

SERIAL PORT:

communication external to the computer is done serially (bit after bit) through this port. It is used to connect communication devices like mouse, modem etc.

PARALLEL PORT:

8 Bit data transfer takes place between the computer and an external device. It is typically used to connect a printer.

GAME PORT:

It is used to connect a joystick for playing games.

IDE (Integrated/Intelligent Drive Electronics) Interface: This interface is used to communicate with IDE Hard disks.

FLOPPY DISK controller:

The FDC can support up to two floppy disk drives. The FDC is connected to the system bus and to the DMA controller. It performs data transfer in DMA mode.

sound card:

This is the card that adds audio effects to the computer by providing interface with microphone and speaker. This is used in multimedia computers.

PERIPHERAL devices:

FLOPPY DRIVES:

1.44 MB & 1.2 MB are two types of popular Floppy Drives.

HARD DISK DRIVES:

ST 506 & ESDI are old types. IDE hard disks are popular because their price to performance ratio is very good. For very high performance, SCSI (Small computer systems Interface) is the ideal option, if price is not a criterion.

CDROM DRIVES:

CDROM drive is used in a multimedia system as it can support all types of CD ROMs be it data CD, audio CD, video CD. It has a great advantage of storing about 650 MB of data in a single CD.

keyboard:

keyboard translates the keystrokes into letters or numbers. These letters are interpreted and the computer CPU depending executes commands on what was sent. Variations in terms of XT/AT, no. of keys, type of keys used may be observed.

mouse:

To interact with the pictures (ICONS), a special pointer device was introduced into the computer world. This device is known as mouse and is connected to the serial port.

The mouse contains a round ball that makes contact with two rollers-one for X-axis (the horizontal) and one for Y-axis (the vertical). Moving the mouse causes the ball to roll, and the ball, which is in contact with the two rollers, causes them to turn. This is used for moving clicking the mouse buttons makes a pointer head on the screen and selection.

SCANNERS:

In addition to keyboards and pointing devices, there is another very common method of getting data into the computer. A scanner is used to scan an image (say from a photo) and editing may be done using a suitable software.

MONITORS:

The monitor receives video signals from the computer video adapter card and displays the video information as pixels (picture elements) on the monitor screen. A variety of monitors ranging from CGA mono to SVGA colour are available for users to choose from (though the former is totally obsolete).

CONFIGURATION SETUP:

This is where we define the system configuration. This is done only when the system is assembled and configured for the first time or when it is upgraded. (One may enter the SETUP by pressing Del key as the system is powered up). Different BIOS support different options but the most essential ones, which are found on all systems, are listed below.

DATE & TIME: It displays the correct Date & Time. It has to be set when system is first installed.

FLOPPY TYPE:

To define the Floppy drives connected (1.2MB or 1.44MB).

HARD DISK TYPE: To select the Hard disk type (Primary or secondary)

DISPLAY TYPE: Its select the types of video adapter used for the system monitor.

CACHE ENABLE/DISABLE:

This category speeds up the Memory access. (Default value: Enable) and defines presence or absence of cache memory.

QUICK POWER ON SELF TEST: Its speeds up the Power On Self Test after you power up the computer.

PASSWORD setting: This allows you to set the system password.

POWER MANAGEMENT: This category allows you to select the type (or degree) of power saving.

LOADING DEFAULT VALUES:

There are many parameters, which need to be defined in the CMOS setup, and one may not want to do so manually. This option loads certain default values, stored in the BIOS ROM, which have been defined by the manufacturer for optimal system performance.

ENABLE/DISABLE ON BOARD FUNCTIONS:

To enable/disable certain onboard functions like Floppy Disk control etc (This applies only to integrated Motherboards where the add ON functions are integrated on the Motherboard itself).

PNP FEATURES: This category is used to configure the pci bus slots.

IDE AUTO DETECTION: This allows you to detect the IDE Hard drives automatically.

SAVING & EXITING:

This allows you to save the new setting value in the CMOS memory and continue with the booting process.

POST (POWER ON SELF TEST):

This POST firmware is stored in ROM on the motherboard. This POST is a series of a simple program to test and catch faults in different components and circuits. It tests the microprocessor, interrupt controller, PPI, DMA controller, ROM, RAM, peripheral controllers etc.

SYMPTOMS:

In case of error detection during POST, indications like error beeps/error messages helps troubleshoot problems.

speaker:

With the help of speaker error beeps, we can troubleshoot faults. Each fault causes the speaker to emit different patterns of beeps.

DISPLAYED ERROR MESSAGES:

When system is powered on, error message will be displayed on the screen (Floppy disk fail), if the video adapter is functional.

DIAGNOSTIC cards:

The advanced diagnostic add on card captures details of POST sequence and displays a hexa code which may be used for in-depth & accurate diagnosis of a POST problem.

CDROM DRIVES:

A computer CD-ROM drive uses small, interchangeable, plastic-encased discs from which data is retrieved using a laser beam, much like music compact disc. And like a music CD, a computer CD-ROM stores vast amounts of information. This is achieved by using light to record data in a form thats more tightly packed than the relatively clumsy magnetic read/write heads a conventional drive must manage.

The drive is controlled by a software in your PC that sends instructions to controller circuitry thats either a part of the computers motherboard or on a separate board installed in an expansion slot.

How a CD_ROM drive works? A motor constantly varies the rate at which CD-ROM disc spins so that regardless of where a component, called DETECTOR, is located in relation to the radius of the disc, the portion of the disc immediately above the detector is always at the same speed.

The laser projects a concentrated beam of light that is further focused by a focusing coil.

The laser beam penetrates a protective layer of plastic and strikes a reflective layer that looks like aluminum foil on the bottom of disc.

The surface of the reflective layer alternates between lands and pits. Lands are flat surface areas; pits are tiny depression in the reflective layer. these surface are record of the 1s and 0s used to store data.

Lights that strikes a pit scattered. But light that strikes a land is reflected directly back at the detector, where it passes through a prism that deflects laser beam to a LIGHT-SENSING DIODE.

Each pulse of light that strikes the light-sensing diode generates a small electrical voltages. These voltages are matched against a timing circuit to generates a stream of 1s and 0s that can understand.

As a wedding minister bringing people together in holy matrimony is one of the most rewarding things I could ever do. When two people willfully decide to commit their ongoing love one to another, it establishes a deep covenantal and unbreakable bond.

Marriage provides the perfect context to grow individually and together. As you give and receive unconditional love, you become increasingly secure and strong as a person. Trust and transparency grow over time as you celebrate the joys and share life's sorrows together.

Recently I officiated a wedding in Central Florida for a Japanese bride and an American groom who met at Walt Disney World. They first laid eyes on one another at It's a Small World, the unforgettable ride that separates the cultural divide. This magical moment led to them taking a journey together on Peter Pan's flight.

Truly the world is all interconnected and interrelated. This couple's love for one another attests to that and further joins East and West together in perfect harmony. The groom popped the question to his bride-to-be on the 4th of July, a surprise engagement with fireworks and people celebrating. It was a small taste of what their lives will be together forever.

Such is what matrimony is all about. The coming together of two vastly unique individuals to become one is magical and wonderful. I as a wedding minister could have no greater pleasure or honor than to seal the deal, tie the knot, and wholeheartedly celebrate the love two have got.

The golf swing is a dynamic movement that demands precise coordination of muscle contraction and relaxation, postural stability, strength, balance and body awareness. That is not to say that we cannot swing a golf club without these elements. The body does a great job in compensating for weakness and faulty movement. However, there is a downside to this compensation. The downside is inconsistency, loss of power, and muscle and joint pain. A well developed golf fitness program will help you develop the physical skills needed to consistently repeat a good golf swing, add power and distance to your shots, and help prevent, reduce and possibly even eliminate golf related pain and injury.

Since countless pga professionals have proven the benefit of strength and conditioning, the demand for golf fitness trainers and training programs has increased tremendously. When looking for a trainer or golf fitness program beware all programs and trainers are not created equal. A sound golf fitness program should be built on the foundation of postural stability, muscle balance, and efficient movement. many golf fitness programs put the cart before the horse by focusing on strength without addressing stability. Be very cautious of programs that advertise they will strengthen your golf muscles. Due to the repetition necessary to master the golf swing those targeted golf muscles are often already over developed and over tight in relation to the rest of the body. This common muscle imbalance causes inefficient muscle recruitment that leads to inconsistency, loss of power and increased incident of pain and injury. A qualified golf fitness professional knows that it takes practically every muscle in the body to complete a golf swing. Performing exercises that mimic the golf swing prior to establishing a strong foundation and good muscle balance will only strengthen the imbalance and lead to further inconsistency and greater chance of injury. As well as a strong foundation in exercise science a good golf fitness trainer or program should have a good understanding of biomechanics as they relate to the golf swing.

It is important to note that it may take a little time for your swing to adjust to your newly efficient body. The best way to see consistent improvement in your game as you train your body is to develop a relationship with a qualified pga teaching professional. Integrating the play better longer fitness program with quality instruction will allow you to get the most out of your practice and playing time. A sound golf fitness program will help prepare your body to perform at its optimal level. Increased muscular efficiency and flexibility allow you to increase power and consistency while drastically reducing chances of pain and injury. You will not only be playing better, but you will be playing better longer!
