Nowadays, computer systems are playing a major role in this modern environment. The world has gone through a phase where there is no hope without a computer system. Practically every sort of business and other organization depend on computer systems to automate their steady procedure. With the development of the technology and starting of computer systems many companies, organizations, and institutes, have shifted to computer-based systems from paper-based systems.

Computers are extremely important in the modern world of today. In the fast moving life of the modern world of today, computers hold incredible significance.

Here are some benefits of computer systems at work;
1. Makes work easier and faster.
2. It can hold a huge amount of information.
3. Reliable.
4. Information management.
5. Accuracy.
6. Improve information.

Role of computer systems in the different environment, mainly we discuss 5 environments in here,
1. Education environment.
2. Business environment.
3. Banking environment.
4. Health environment.
5. Communication Environment.

1.2 Education Environment.

Computer technology has had a deep impact on the education sector. Thanks to computers, imparting education has become easier and much more interesting than before. Computers have changed the way we work, be it a profession. Therefore, it is only natural that the role of computers in education has been given a lot of importance in recent years. This is additionally in light of the fact that the education system has made computer training a piece of school educational programs. Considering the using of computer technology is practically every circle of life. Many schools have made on their usage of computers by making greater computer labs. 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.

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.

Task 02

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.
Computer
• 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.

Data
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.

Information
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.
1. Internal
2. Hardware
3. Software
4. Firmware
5. Peripheral

2.3 Internal Devices

All the devices that are installed on the computer can be called as \”internal devices\”.
1. Processor
2. Motherboard
3. RAM
4. Sound Card
5. Network Card
6. Video Card

1. Processor
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
Dual core
Core 2 Duo
Core i3
Core i5
Core i7

• AMD processors
Athlon II
E2 series
A4 series
A6 series
A8 series
A10 series

2. Motherboard
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.

2.4 Hardware

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
4) Storage/Memory
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,
• Keyboard
• Mouse/Touchpad
• Webcam
• Microphone
• Scanner
• Optical character reader (OCR)
• Optical mark reader (OMR)
• Magnetic ink character reader (MICR)
• Barcode reader

Keyboard
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.

Mouse
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

Microphone
The Microphone can be called a device that translates sound vibrations in the air into electronic signals or transmits them to a recording medium.
