Basic components of Computer system:
21. Basic components of Computer system:
2.Software: It is a set of programs that controls the computer system.
Types of Software:
1. System Software: It is program that allows the hardware to run
properly and allow the user to communicate with the computer.
Examples of System Software:
Compiler
Operating System
Anti-virus software
Interpreter
22. Basic components of Computer system:
1.Application Software: It is a program that allows
user to do specific tasks.
Examples of Application Software:
Ms Office
Calculator
Notepad
Web browsers
24. 1.Measurement Application: There are many measurement
applications using the sensors and other electronic hardware.
ICT APPLICATIONS
25. Examples of measurement applications include:
a) Weather stations: Weather stations are set upto
automatically gather data from environment. They make
use of variety of sensors to measure rainfall, temperature,
wind direction and speed, pressure, and humidity.
27. Examples of measurement applications include:
b) Measuring a patient’s vital signs in a hospital:
Computer is used to measure the patient’s blood pressure,
heart beat rate, body temperature, blood sugar level, etc.
28. Examples of measurement applications include:
c) Measuring pollution in the river: Computers are
used to measure the pollution level in the river using
various sensors and ADC. (Analog to Digital Converter)
30. 2. Microprocessor in control applications: In controlled
applications, Microprocessor, computer, and sensors are used.
Some control applications include:
31. 2. Microprocessor in control applications:
a) Automatic Oven/ Cooker: It has a temperature sensor which checks
the current temperature value with the preset value. It the current
temperature value is equal to preset value, then heating element is switched
off by the microprocessor automatically.
32. 2. Microprocessor in control applications:
b) Central Heating system: In this a gas supply is used to
heat water in a boiler. Sensors are used to check the current
temperature value with preset value.
35. 3. Manufacturing Applications:
Robots are used in many areas of manufacturing, from
heavy work right through to delicate operations.
Examples
1.paint spraying of car bodies
2.Welding body work on cars
3.Manufacturing electrical goods
36. 3. Manufacturing Applications:
Advantages of Robots:
1. They can work in environments harmful to human operators.
2. They can work non-stop(24/7).
3. Higher productivity
4. They don’t need holidays.
Disadvantages of Robots:
1. They can cause higher unemployment.
2. The initial set-up and maintenance of robots can be expensive.
38. The term topology applicants to different formats of
the arrangement of computers in a network.
TOPOLOGY
39. TYPES OF TOPOLOGY:
1. Bus Topology:
The Bus Topology is composed of a single link connected to many
computers.
All computers on this common connection receive all signals
transmitted by any attached computer.
The Bus device is the backbone of Bus Topology, if bus fails, the entire
system fails.
40. TYPES OF TOPOLOGY:
2. Star Topology:
The Star topology connects many computers to hub computer.
The nodes in this type of the network are attached to separate
lines, all of which lead to the hub.
The Hub is the backbone of Star Topology, if Hub fails, the entire
system fails.
41. TYPES OF TOPOLOGY:
3. Ring Topology:
• The Ring Topology uses multiple links to form a circle of
computers.
• Ring Topology also called as Circular Topology.
• It consists of a closed loop, with each node connected on a
loop.
• A token (data), consisting of a short message, circulates
continuously around a loop and is read through a token
ring adapter card in each mode as the token passes by.
