The upstream is one of the processing from the service provider or the manufacturer that helps in providing the various types of information, raw materials, components and the finances for creating the different types of products and the services in the market.
The Upstream is refers to the first step for producing the products and then the products are deliver to the customers or users in the form of upstream in the supply chain system.
Therefore, Upstream is the correct answer.
1. terry: computer worm
2. _ biggest risk: Natural disasters
3. William is working with data: procedural error
4. infamous e-mail: phishing
5. intentional/ unintentional threats: harmful purpose/ not harmful
6._ would result in systems brought down: Denial-of-service attacks
7. which doesn't require a security plan: all of them do
8. Blaire is the director: procedures
9. handling of workstations: hardware
10. which is not an example of software security: data backups
The questions were in a different order for me, so I tried to specify.
ALU and CU are the major units in CPU to execute different operations and process information. ALU is used to process arithmetic and logic operations while CU controls the data in/from input, output devices and memory. All the data has been processed in the form of binary data.
As we know that, CPU is the short form of central processing unit. It consist of two major parts Arithmetic and logic unit (ALU) and Control Unit (CU). Both these parts contribute to perform a complete operation in computer. The whole operation has been performed in following sequence using these two components.
The information that need to processed will arrived from some input device or memory location. This information will be interpreted in Machine language that is Binary language.
Control unit is used to control the flow of data and read write operation from/to memory or some I/O device. For Example, If user input data from an input device and want to process and store it in some memory location. The control unit send the signal to read data from input device, process it with the help of ALU and then write it on some memory location.
ALU is Arithmetic and logic unit that perform the operation according to the operators in given instruction that need to be processed. For Example, If user want to add to two inputs and show the result on some output device. Control unit will read the data from input device, interpreter interpret the instruction that what operation need to be performed in machine language. As the addition is an arithmetic operation so, arithmetic unit perform this operation. The result will be again interpreted in high level language and send to write on output device with the help of Control Unit.
An information system is essentially made up of five components hardware, software, database, network and people. These five components integrate to perform input, process, output, feedback and control. Hardware consists of input/output device, processor, operating system and media devices.
An information system is a set of command that i used to analyze available information in order to create a better decision for the company.
Which means that information will not be able to do any function of it does not possess the initial information, to begin with, so we can conclude that information is a major component of the information systems
