Assignment 2Author: Shuishbaev NuruddinGroup: CS-2009Task 1. Identify the components of the system1.Identify the 4 components of computer system.Answer: Processor Main memory(storage)Input devicesOutput devices2. What is the environment?Answer:A computer system uses many devices, arranged in different ways to solve many problems. This constitutes a computing environment where many computers are used to process and exchange information to handle multiple issues.3. Identify the components of CPU?Answer:The CPU is made up of three main components, the control unit,the immediate access store and the arithmetic and logic unit.The control unit controls the flow of data within the system. The control unit controls and monitors communications between the hardware attached to the computer. It controls the input and output of data, checks that signals have been delivered successfully, and makes sure that data goes to the correct place at the correct time.
Immediate access storeTheimmediate access storeis where the CPUholds all the dataandprogramsthat it is currently using. You can think of it like the numbers typed into a calculator – they are being stored inside the calculator while it processes the calculations. The immediate access store is often referred to as theregistersin the CPU.Arithmetic and logic unitThearithmetic and logic unit (ALU)is where the CPUperforms the arithmetic and logic operations. Every task that your computer carries out is completed here. Even typing into a word processor involves adding binary digits to the file, and then calculating which pixels on the screen should change so that you can see the characters.Task 2. 1. What are the input devices? Answer: In computing, an input device is a piece of equipment used to provide data and control signals to an information processing system such as a computer or information appliance. Examples of input devices include keyboards, mouse, scanners, joysticks, and microphones.2. What are the process devices?Answer: Processing devicesare the components responsible for the processing of information within the computer system. This includes devices such as the CPU,memoryandmotherboard.3. What are the storage devices?Answer:Storage devicesare components which allow data to be stored within a computer system. This includes devices such as hard disk drives andcompact diskdrives.4. What are the output devices?Output devicestake data from the computer system and convert it to a form that can be read by humans. For instance amonitorcreates a visual electronic displayto output information created by the processor to the user.(printer, speaker,headphone, etc)
Task 3.a. Complete the following chart by converting the numbers given in one of the notations to the other two. Show calculationsBinaryDecimalHexadecimal101010101341155100010010154955110113D11111010250FA10101111175AF1110010114591CB11101010019373A91010101111002748ABC11110110119873DBb. What is the minimum number of bits that can be used to represent the decimal number 213? (Hint: convert 213 to binary.)Answer: 11010101c. What is the minimum number of bytes that can be used to represent the decimal number 914?Answer: binary 1110010010, 10 bit = 2 byte d. What is a purpose of using hexadecimal notation?Answer: Hexadecimal numerals are widely used by computer system designers and programmers, as they provide a human-friendly representation ofbinary-codedvalues. Each hexadecimal digit represents fourbinary digits, also known as anibble, which is half abyte. For example, a single byte can have values ranging from 00000000 to 11111111 in binary form, which can be conveniently represented as 00 to FF in hexadecimal.e.What is ASCII code? ASCII (American Standard Code for Information Interchange) is the name of the table; in some common printable and non-printable characters, numeric codes are mapped. The table was established and standardized in the United States in 1963.The ASCII table defines codes for characters:decimal digits;Latin alphabet;national alphabet;
