The educators and students use computers to complete specific assignments. The teachers, they use computers to influence practical realistic outlines which to can empower students to learn successfully. Students use computers in composing of notes and examining of electronic books which can be downloaded from the web.
There are some new technologies in the education field.
1. RFID Based attendance system.
The point of this undertaking is to keep up the record of the students\’ attendance by using RFID labels. Every student is issued with his/her approved tag, which can be used for swiping in front of the RFID reader to record their attendance. In the majority of the universities and schools, attendance is recorded physically – such a procedure expends heaps of time. In this proposed system, attendance system is actualized by using propelled remote innovation \” RFID\”. Just the approved students are furnished with the RFID labels. This label comprises of an inbuilt integrated circuit for putting away and handling data.
1.3 Business Environment.
Computer technology has great application in almost all kind of business. All sorts of organizations are depending on computers for mechanizing their customary procedures. Businesses use a wide assortment of the database, administration data frameworks, data sharing stage, information sharing system, web, machines, hardware and so forth which exceptionally depend on computers. The use of computer technologies is not only in the field of finance or marketing, it is also being used by the payroll system, human resource departments, inventory control management system etc. Computer technology help to play out the directing business errands mush faster when contrasted with the traditional method for doing things manually.

The only disadvantage is that a full-fledged installation of all the computerized systems in hospitals is a lengthy and costly process. There are, however, some hospital systems which already work on the basis of computers.
Here are some projecting uses of computers in hospitals
1. Positron Emission Tomography (PET).
A positron emanation tomography (PET) examine is an imaging test that uncovers how your tissues and organs are working. A PET output uses a radioactive medication (tracer) to demonstrate this action. This sweep can now and then identify ailment before it appears on other imaging tests. The tracer may be injected, swallowed or inhaled, depending on which organ or tissue is being studied. The tracer gathers in regions of your body that have larger amounts of synthetic action, which frequently relate to zones of the malady. On a PET output, these territories appear as brilliant spots. A PET sweep is valuable in uncovering or assessing a few conditions, including numerous malignancies, coronary illness and mind issue. Frequently, PET pictures are consolidated with CT or MRI sweeps to make exceptional perspectives.

Banking sector gives clients the ability to use online banking or e-banking with the help of cloud computing.
It is more useful, effective and efficient that clients can do their transactions whenever and anywhere they want.
Explain what makes Computer system and draw a hierarchical chart to represent how they are categorized (Internal, Input, Output, and Peripheral) with suitable examples.
2.1 A computer system.
A system is a collection of elements that work together to archive a common objective. A computer system consists of hardware, software, firmware and liveware elements that support information processing.
• A programmable machine that inputs, process, and outputs data.
• A computer is an electronic device that can store and process data, converting it into information that is useful to people.
Raw data are numbers, characters, images or other outputs from device to convert physical quantities into symbols, in a very board sense. Such data are typically further processed by a human or input a computer, stored and processed there, or a transmitted (output) to another human or computer.
Raw data is a relative term; data processing commonly occurs by stages, and the “processed data” from one stage may be considered the “raw data” of the next.
When you input data to the computer, the computer will process those data, and the information will be output from the computer. To output information, you will able to use many types of devices.
Structure Chart of a computer system
2.2 Hierarchical chart of the computer system.
The computer system is divided into five items.
2.3 Internal Devices
All the devices that are installed on the computer can be called as \”internal devices\”.
4. Sound Card
5. Network Card
6. Video Card
The first processor released by Intel was the 4004 processor. The processor is often thought as the “Engine” of the computer. It can also be called as CPU (Central Processing Unit). CPU handles all instructions it receives from hardware and software running on the computer. Processors produce heat, so they are covered with a heat sink or cooling fan to keep them cool and running smoothly. All computers require some type of CPU. Without CPU the computer does not work. Processors are available in three types.
• Socket Type (PGA)
• Slot Type
• Socket Type (LGA)
The major two types of processors brand available in the market and the latest processors of them.
• Intel processors
Core 2 Duo
• AMD processors
The motherboard also called mainboard of the computer. The motherboard is a printed circuit board that is the foundation of a computer. All the hardware devices of the computer will connect to the motherboard directly or indirectly. This motherboard will support the communication between all the hardware devices on the computer. Most of the newer motherboards come with the “onboard device” concepts which integrate a lot of interface cards to the motherboard itself.
Latest motherboards are having newer and faster interfaces for connecting devices. IDE interfaces are replaced by SATA. AGP slots replaced by PCI express slots,
Overview of the motherboard,
3. Sound Card
A sound card is an expansion card or IC for producing sound on a computer that can be heard through speakers or headphones. Most of newer motherboards we can get a sound card as an onboard device. Separate interface cards are mostly in PCI slot.
4. Video Card (VGA)
VGA (Video Graphics Array) used to connect the monitor to the motherboard using the VGA card. A video card is used to process images so they can be displayed on the monitor. A good video card can make a big difference in the quality of the graphics, so this is particularly important if you play games or work with photography and video.
All the devices on your computer system that we can touch can be called as “hardware devices”. Without any hardware, the computer system does not exist and software could not be used. We can classify hardware into following devices
1) Input Devices
2) Output Devices
3) Central Processing Unit
5) Communication Devices
2.4.1 Input Devices
The devices that we use to input data to the computer system called as “input devices”. Input devices are,
• Optical character reader (OCR)
• Optical mark reader (OMR)
• Magnetic ink character reader (MICR)
• Barcode reader
The keyboard will be one of the main input devices of the computer. Using this keyboard we can input letters, numbers, and symbols. Also, some of the main commands can be input by this keyboard.
The mouse can be called as one of the main input devices on the computer. Without this mouse, the activities on the computer will be so difficult, because most of the computer activities involve the mouse. On a standard mouse, we can see two buttons named, “left mouse button” and “right mouse button”. The mouse is placed on a flat surface like a mouse pad or a desk and is placed in front of your computer
The Microphone can be called a device that translates sound vibrations in the air into electronic signals or transmits them to a recording medium.
