image into dots that the computer can understand .To scan text, optical This holding place is known as memory also called main storage and is internal to the computer consisting of RAM and possibly ROM. Central processing unit (CPU) or processor Cache memory is a type of very fast memory that is used to improve the speed of a The input and output devices are discussed in details in chapter 2 of the module. to the C language (part 1/2), Introduction 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. programs that are static (not changing often) and mass-produced. o Digital Camera Used to take electronic pictures of an object. The benefits of secondary storage can be summarized as follows: These benefits apply to all the various secondary storage devices but, as you will see, some devices are better than others. However, only one read/write head can operate at any one time. Northbridge -Definition: Refers to the System Controller component of a Pentium chipset, responsible for integrating the cache and main memory DRAM control functions and for managing the host and PCI buses. This requires a transmission rate of 4692 bits per second. We're left with 1, which goes in 2^0, and we subtract one to get zero. The control unit coordinates and controls all the operations carried out by the But the DVD will undoubtedly gain a place as the successor to the CD ROM and is playing an important role in the blending of computers and entertainment centers. Microarchitecture, also known as Computer organization is a lower level, The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. We can easily see that the number 3= 2+1. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. of Maryland. Begin by thinking of a few examples. integration that confines several physical components per small elements thumb The lecture Explain how information is stored in a computer Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. Magnetic disks and drums are examples of direct-access storage media. Optical storage technology is categorized according to its read/write capability. Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." They are shown in the block diagram below. ROM: A mask programmed read only memory that can be only be produced by the manufacturer. To provide an in-depth presentation of computer hardware and software with computer doubling it in some cases. The CPU is connected to the main memory by three separate buses. came UNIVAC (universal automatic computers). It Converts an a lithium battery. The DVD drives will not replace the magnetic hard disks. Students who are still learning the basics of computer repair, like what components are involved in what operation, will frequently assume that all boot issues are due to a hard drive failure. Although the EISA bus is backwards compatible and not a proprietary bus it never became widely used and is no longer found in computers today. Older Zip disks hold 100MB, newer ones hold 250MB and cost $8-$10 a piece (Floppies hold 1.4MB and cost around $2). troubleshooting and upgrading computers. Minicomputers It is a blueprint and functional description of requirements and design implementations for the various parts of a computer, focusing largely on the way ()by which the central processing unit (CPU) performs internally and accesses ()addresses in memory. Merriam-Webster Dictionary The definition from the (): "one that computes; specifically : a programmable electronic device that can store, retrieve, and process data", What different types of computers are there ? To convert from hexadecimal to binary, simply look at the chart above and replace each digit in the hexadecimal number with its corresponding four-digit binary number. the capacity to hold significantly more data than a 5-1/4 inch diskette. Tracks within a cylinder are numbered according to this vertical perspective: A 20-surface disk pack contains cylinder tracks numbered 0 through 19, top to bottom. Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. j!)+v%""s!-+ 2MYI9RVgJm

The real time clock chip is a battery-operated chip that maintains basic settings and the system time. This process continues until we have a remainder of 0. Assembly language is translated into machine code using an assembler before they can be executed. The number 81 in binary would also have a 1 in the 2^0 column. (20 minutes presentation + 5 minutes for A command based interface is quick to operate and very flexible, but the user needs to learn all the commands and type them in correctly. A mainframe is another giant computer after the super computer and can also links that I will post to other websites. To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. And, the access time is independent of the storage location. Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. Instead of using the digits 0-9, we only use 0-1 (again, if we used anything larger it would be like multiplying 2*2^n and getting 2^n+1, which would not fit in the 2^n column. Computers cannot do any useful work without instructions from software; thus a combination of software and hardware (the computer) is necessary to do any computerized work. There is also the possibility of errors introduced by software. monitor, Keyboard, Mouse, system unit etc. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. Twelve would be 12*10^0, or 10^0(10+2), or 10^1+2*10^0, which also uses an additional column to the left (12). Hexadecimal is more compact than binary but is still based on the digital nature of computers. B. The processor also stores the instructions being currently executed into the main memory. Chapter 4 (Processor Architecture) The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. A set of programs associated with the operation of a computer. of computer is also helpful for forecasting weather reports worldwide. details than what we will cover in the lecture. In such a system a task is broken down and shared among processes for faster execution. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. 6.823 is a study of the evolution of computer architecture and the factors influencing the Region one is USA and Canada, while Europe and Asia is region two. Knowledge Network of Toyota. Chapter 2- Basic Organization of a Computer. HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. In order to synchronise the various steps carried out during the fetch-execute cycle, all the processors have an internal clock which generates regularly timed pulses. to do something, like save the file. Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. Introduction to Computer and its components infrequent operation - most of the time the memory is used as a ROM. The sector method is used for diskettes as well as disk packs. ); it can be written to, but only The shape and layout of a motherboard is called the form factor. http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-, L.N.Gumilyov Eurasian National University, Jomo Kenyatta University of Agriculture and Technology, Kwame Nkrumah University of Science and Technology, Introduction to Entrepreneurship (Introduction to Entr), Human Resource, Organizational Behavior, (HR, OB), Bachelor of science in accountancy (150062), FOUNDAMENTALS OF NURSING SCIENCE (NRSG 212), Geometrical Optics and Mechanics (PHY112), Avar Kamps,Makine Mhendislii (46000), Power distribution and utilization (EE-312).

We learned earlier that there is a 1 in the 2^0 column if the number is odd. and accesses addresses in memory. When you hear reference to a "flash BIOS" or doing a BIOS upgrade notes posted are not meant to substitute for the text The address bus is used for communicating the physical addresses of computer memory elements/locations that the requesting unit wants to access (read/write). once. Let's try the number D=55. floppy disk controller. Lecture Notes Computer System Architecture Notes: Computer System Architecture notes provide the student with the most updated notes on the subject and provide reference books that are up to the curriculum. These notes are easy to interpret for aspiring students and are the best set of references for computer system architecture during revision. works by letting you "burn" programs onto blanks once and then letting you Writing and understanding programs in assembly language is easier than that of machine language. Web2 Lecture Overview Course description Chapter 1 : Introduction Overview of computer organization and architecture The main components of a computer An example system: wading through the jargon Standards organizations Historical development of computers The computer level hierarchy The Von Neumann model generation saw the introduction of more complex ALU and CPU, the use of high Because of their digital nature, a computer's electronics can easily manipulate numbers stored in binary by treating 1 as "on" and 0 as "off." Several disks can be assembled into a disk pack. (0's and l's). In order to execute a high-level language program, it should be translated into a machine language either using a compiler or interpreter. just like burning a CD-R, and it is comparable in terms of its flexibility. ii. Input Devices Icons represent programs, groups of programs, folders, devices and files. A motherboard allows all the parts of your computer to receive power and communicate with one another. versions, like the CD-ROM's. PROM, but it does require the erasing light. Explain the different hardware units of a computer system such as input, Similarly, the statement a[n-1]*2^(n-1) + a[n-2]*2^(n-2) + + a[1]*2^0 has a power of two removed. They can be divided into; Are programs for user to do their jobs e.g. unit, memory (ROM, RAM). However, you probably want to store the data you have used or the information you have derived from processing; that is why secondary storage is needed. The organization in this case is vertical. more emphasis on the more technical aspects of computing such as Two's column: Dividing 162 by 2 gives 81. If we wanted to put a larger number in column 10^n (e.g., 10), we would have to multiply 10*10^n, which would give 10^(n+1), and be carried a column to the left. A bit is used to represent information in the computer. Almost all the computers used nowadays are digital computers and we will The small circuitry that resulted improved the processing speed i.e. Furthermore, memory is limited in size, whereas secondary storage media can store as much data as necessary. They can be linked to smaller increased.

High level language permits the user to use understandable codes using the language structure. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. notes posted are a superset of what I will go over during The EISA bus provided 32-bit slots at an 8.33 MHz cycle rate for the use with 386DX or higher processors. A little glass window is installed in the top of the In 1833, Prof. Charles Babbage, the father of the computer, developed a machine These are devices which are used to store huge information for future use. abacus and the improvements in the calculating device in that age were slow. The two components (hardware, software) will be discussed later in other chapters. this unit. When you play movies, your hardware (MPEG decoder. process millions of instruction per second and capable of accessing billions of It is designed to perform a specific function and cannot be changed. We know that: and so on. Free download engineering ppt pdf slides lecture notes seminars, copyright@engppt.com. This type of programs is called machine language programs and the programming language is called machine code. refer to the In assembly language mnemonic codes are used to develop program for problem solving. Furthermore, data security is improved because if a disk fails, the disk system can reconstruct data on an extra disk; thus, computer operations can continue uninterrupted. (2mks) (b). Mainframe computers What we're doing here is finding the largest power of two within the number (2^2=4 is the largest power of 2 in 5), subtracting that from the number (5-4=1), and finding the largest power of 2 in the remainder (2^0=1 is the largest power of 2 in 1). stream The term mainframe was mainly used for earliest computers as they were big in size though today the term is used to refer to large computers. Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. o Scanner allows you to scan documents, pictures, or graphics and view The EISA bus is found on Intel 80386, 80486 and early Pentium computers. This computer is commonly used in big hospitals, air line reservations companies, and many other huge companies prefer mainframe because of its capability of retrieving data on a huge basis. information and issue commands to the computer. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. Data can be obtained quickly from anywhere on the media. implementations for the various parts of a computer, focusing largely on For example, if the data bus is 8 bits wide, and each instruction is 16 bits long, then the processor must access the main memory twice during each instruction cycle. They are of advanced technology i. the micro era based on large scale Diskettes became popular along with the personal computer. Many new PCs come with Zip drives built in addition to floppy drives. This is write, because when they change their code they can create new PROMs without Random-access storage media refers to magnetic core, semiconductor, thin film, and bubble storage.
