computer architecture ppt lecture notes

and that this is equivalent to (1*2^1)+(1*2^0). infrequent operation - most of the time the memory is used as a ROM. A graphical user interface (GUI) allows the user to interact with the system using Windows, Icons, Menus, and Pointers to control the operating system. I don't mean that hard drives last longer than memory modules or video cards in the pure MTBF (Mean Time Between Failure) sense, I mean they are rarely at fault when you're called in to repair a PC. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a time, but writing is a slow process and uses non-standard voltages (usually higher voltages around 12 volts). Record the 0, carry the 1. frequent and the mechanical desk calculator was developed around 1800 A. may be entered into a computer system. classified and known as super computer. DVD movies are made in two "codes." Not all computer hardware uses voltage, however. does not cover memory design in any depth and I will provide detailed Motherboards have come a long way in the last twenty years. Define computer data storage. CD-ROM's, for example, use microscopic dark spots on the surface of the disk to indicate "off," while the ordinary shiny surface is considered "on." written and quite useful -- they were written by the instructor for called a mother board. information and issue commands to the computer. Hard drive failures are generally pretty easy to troubleshoot, in part because the operating system will include tools to report on the hard drive's reliability when it's accessible.. It Converts an the micro era based on large scale integration that confines several physical components per small elements thumb size IC, hence the size reduced. Over 100's of millions have been sold, making it the de facto standard. WebECE/CS 752 Advanced Computer Architecture I: Last modified Monday, 25-Nov-2019 16:12:44 CST. x[r+&YU@lJSvB%d#QTD[/\{g\\S All the processor activities, such as fetching an instruction, reading data into the memory register etc. It is the main part of a computer system like the brain of a human being. The transistor is WebLecture #4-5: Computer Hardware (Overview and CPUs) CS106E Spring 2018, Young In these lectures, we begin our three-lecture exploration of Computer Hardware. Data thus saved can be restored to the hard disk later if needed. a similar course at Univ. very low i. next change came after about 1600 years. The outer gold layer is semi transparent, to allow reading of the underlying silver layer. WebSymposium on Computer Architecture (ISCA), 1994 Lecture notes will be available in pdf and powerpoint formats, with 6 per page for pdf for conventinent printing.. (Powerpoint is for instructors who want to give lectures themselves based on CS 252.) Fault Diagnosis Fuller F., Larson B., Computers: Understanding Technology(Second Edition) `P|U`J]Jsf/=*mhA*x+*v PuHMf yoPpile.K9^bEjed*csaE'ZaT1w@gTo7t The amount of data on a tape is expressed in terms of density, which is the number of characters per inch (cpi) or bytes per inch (bpi) that can be stored on the tape. (2mks) (b). This demanding shopping list is a description of the optical disk, like a CD. dj z(l6uHyB"C]Iie7tHDXWq@vd4KfqS)YZT&;"v%LqNm!ZTJ UWBD@^-1QA+'6b"V0s>x$*Y l(7`yAP. There are different types of disk packs, with the number of platters varying by model. The most prominent optical technology is the CD-ROM, for compact disk read-only memory. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices Temporary Result: 11 New D=40 D does not equal 0, so we repeat step 2. for using the C to LC3 You will see that it is the same procedure, but with sixteen digits instead of 10 or 2. Power Supply Troubleshooting They have higher main memory capacity, reliable and increased processing power (have the capability of holding more than one set of instructions and operate on them) than the second generation computers. This computer is commonly used in big hospitals, air line reservations It may also be defined as the science and art of selecting and interconnecting hardware components to create computers that meet functional, performance and cost goals. Extended Industry Standard Architecture (EISA) also known as Extended ISA, EISA is a standard first announced in September of 1988 for IBM and IBM compatible computers to compete with the IBM MCA bus. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. 10100011=(1*2^0)+(1*2^1)+(1*2^5)+(1*2^7)=1+2+32+128= 163.

Begin with one-bit binary addition: 1+1 carries us into the next column. A. We know that since it is odd, there must be a 1 in the 2^0 column (a[0]=1). The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. The cost of computers decreased and the speed increased. 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 ? Continuing the "CD" analogy, this technology is analogous to a reusable CD-RW. usually called personal computers since they are designed to be used by 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. WebBIT 1101 Computer Architecture complete lecture notes for first years and all - P. Box 342-01000 - Studocu. computational power. college.

In decimal form, 1+1=2. The two components (hardware, software) will be discussed later in other chapters. Next, we focus specifically on the CPU (Central Processing Unit). Particularly step 3, "filling in the zeros." It is used more like a ()hard drive than as ()RAM. Explain how information is stored in a computer 17. So can be able to read and write into the main memory (RAM). must match the DVD region. We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. During interpretation no object code is produced, and so the program has to be interpreted each time it is to be run. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. There is more than one way of physically organizing data on a disk. Therefore, we should rewrite it such that we ascertain the value of each column individually, putting in 0's and 1's as we go: Now that we have an algorithm, we can use it to convert numbers from decimal to binary relatively painlessly. The speed of these machines was described in microseconds (1/1000, 000 of a second). Perhaps more important than capacity, however, is the convenience of speed. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. Programmable ROM (PROM): This is a type of ROM that can be programmed using special equipment (a PROM programmer. The DVD drives come in 2X, 4X, etc. 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). The first IBM PC motherboard had only a processor and card slots. They support concurrent users. This computer is not used as a PC in a home neither by a student in a college. slower and less costly compared to mainframe computers but more powerful, State three types of computer buses. The lecture Super computers are biggest in size, the most expensive in price than any other is classified and known as super computer. smaller cheaper and produced less heat than vacuum tubes and consumed less Analog This places the data in diagonal bands that run across the tape rather than down its length. They were Super computers are biggest in size, the most expensive in price than any other is This is similar to the way a CD-ROM recorder works by letting you "burn" programs onto blanks once and then letting you read from them many times. When we first learned about numbers, we were taught that, in the decimal system, things are organized into columns: such that "H" is the hundreds column, "T" is the tens column, and "O" is the ones column. Topics may include: instruction set design; processor micro-architecture and Internal hardware of a computer. (Photo openphoto.net. Used with permission.) I. modes, processor registers, and address and data formats. contains materials that are frequently examined. The mechanism for reading or writing data on a disk is an access arm; it moves a read/write head into position over a particular track. It is a Record the 0, carry the 1. Output All the tracks thus encountered, in the same position on each disk surface, comprise a cylinder. the capacity to hold significantly more data than a 5-1/4 inch diskette. A rule of thumb among computer professionals is to estimate disk needs generously and then double that amount. Add 1 from carry: 10+1=11. Writing and understanding programs in assembly language is easier than that of machine language. Practically, we can simply keep a "running total", which now stands at 11 (a[1]=1 and a[0]=1). Pages 4-. The lecture Chapter 1- Fundamentals of Computer Design. The CPU of a The first place to start is always confirming that the power supply is operating properly. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. Furthermore, graphics images and audio and video files require large file capacities. When you play movies, your hardware (MPEG decoder. It controls and monitors the running of application programs. Similarly, multiplying by 2 shifts in the other direction: {a[n]*2^n + a[n-1]*2^(n-1) + + a[1]*2^1 + a[0]*2^0}/2. Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare. This type of programs is called machine language programs and the programming language is called machine code. integration that confines several physical components per small elements thumb Central Processing Unit is implemented in a single piece of silicon device known as a computer chip. They made use of vacuum tubes to store and process information. once. Secondary storage is necessary because memory, or primary storage, can be used only temporarily. Microarchitecture, also known as Computer organization is a lower level, A CD-RW allows you to read, write, erase and write again. Follow the same rules as in decimal division. came UNIVAC (universal automatic computers). The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. gigabytes. 6.823 is a study of the evolution of computer architecture and the factors influencing the For the number 163, this works as follows: Temporary Result: 01 New D=81 D does not equal 0, so we repeat step 2. 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. At the end of the chapter the learner shall be able to; Icons represent programs, groups of programs, folders, devices and files.
