In 4th chapter I learned about CPU and other aspects related to it such as RISC and CISC.CPU stands for central processing unit and it is very suitable name for it as it processes the instructions that it gathers from files. Following diagrams explain the basic architecture of CPU: CPU performance is given by the fundamental law: Thus, CPU performance is dependent upon Instruction Count, CPI (Cycles per instruction) and Clock cycle time. And all three are affected by the instruction set architecture. Instruction Count CPI Clock Program x Compiler x x Instruction Set Architecture x x x Microarchitecture
We can see in Fig. 1, that the embedded computing interacts with their physical environment which can early predict the health problem, secure the sensitive data and enable the uninterrupted operation. Here the paper defines [2], in Figure 1, the computing unit characterizes the quantitative property set C and it is time-varying. Similarly, the physical unit in CPS characterizes the physical property set P and it varies over time and space. For instance, in members of C it includes server utilization, the duty-cycle and control- algorithm during communication.
Components Computers have one or a lot of big or small R-A-M chips inside. RAM chips are a random access memory chip inside, the computer uses it to store information that will be used anytime or used to store something like the copy clipboard(The copy clipboard is the thing that stores what you copy to paste later) to delete/change later. There is also a spinning or solid state hard drive that uses DVD like disks that stores information like your video games, pictures, or other things. A CPU is the thing that your computer uses to do all the processing work, like our brain but not like it. CPU stands central-processing-unit.
Task 1- Hardware components 1. Motherboard- The motherboard is a circuit that links hardware components together to allow them to communicate and receive power through a bus system. The bus is a series of wires that transfers data packets between components. 2.

This is when various different patterns and colours are used as well as objects; all of these allow the user to interact personally with the interface. Colour It is very important that when designing an interface that you
The second is storage the fees of a memory process referring to the retention of information. The third phase is the retrieval the process
A Software B Desktop computers C Laptop computers F PC I MAC D Tablet E Server G Computer DEFINITION A A set of instructions that guides the hardware and tells it how to accomplish each task. Example: web browser, word processors, etc.
Layer three, the network layer, takes network addresses and makes them physical while “routing” data determining whether or not data is sent from the sender to the receiver. In the network layer encloses data in a packet then sends the packet to the data link layer, the second layer. The data link layer transforms the packets into frames. Doing this allows the data to be transmitted in the physical layer. A known hardware device that performs at this layer is a NIC or a network interface card.
• PRIMARY DOMAIN: The primary domain for this case study is Information technology. • SECONDARY DOMAIN: The secondary domain is Management - SME management • SECTORS:
And a computer system can be divided into 4 components: the operating system, the application programs, the uses, and the hardware. Without operating system we cannot use the computer. Booting Process To start the boot procedure, turn on the PC. This is known as a frosty boot.
The human race has got to see some of the top best inventions during the 20th century, for example- the radio, the airplane, nuclear power, automobile, and the one that has by far made human life easy and efficient is the computer. The invention of the computer has led to some of the most significant concepts, ideas, and inventions that eventually led to the evolution of human life. And the major ones are, the internet, long distance communication, easy and safe research and much more! The computer was invented by Charles Babbage, an English mechanical engineer, and polymath who is also titled as the “father of computers”.
The information system provides the basic data on the informational database. To the enterprise, the information system has two subsystems are related. There is data processing or information supplying sub-system and a decision making sub-system. The responsible the data processing system are for acquiring, coding, processing and forwarding the information for the activity and operation. The responsible for decision making subsystem are the effect of directly or indirectly with management processes from data-processing systems.
A computer has already become an inseparable part of life. It helps a doctor in his diagnosis; it helps an engineer in his multifarious activities; guides a pilot or a navigator to safety; it helps a public or a private official or businessman in more ways than one. It is an important part of every institution, every office and every establishment public or private in several countries. Accept it or not, the computer has invaded the work place.
The source transmits the data and the receiver receives it. The purpose of Data communications is to provide the rules and regulations that allow computers with different disk operating systems, languages, cabling and locations to share resources. Networking is the practice of linking two or more computing devices together for the purpose of sharing data. Networks are built with a mix of computer hardware and computer software. All of student uses technology for searching information, storage data for backup, sending information and share knowledge with their friends through email or any communication network.
Components of Computer-Based Information System Figure 2.5: Major components of CBIS There are five major components of CBIS like hardware, software, data, people and network as shown in the figure 2.5. • Hardware Resources Machines: Computers and other equipments along with all data media. Machine is the one in which data is recorded and saved. Computer system peripheral: A computer peripheral is an external object that provides input and output for the computer.
