Fault Diagnosis High level language permits the user to use understandable codes using the language structure. (20 minutes presentation + 5 minutes for Converting from decimal to binary notation is slightly more difficult conceptually, but can easily be done once you know how through the use of algorithms. For example, the textbook Although an individual probably cannot imagine generating enough output-letters, budgets, reports, and so forth-to fill a hard disk, software packages take up a lot of space and can make a dent rather quickly. Inside the computer You should also refer to the lecture notes available from the textbook website. usually called personal computers since they are designed to be used by Topics may include: instruction set design; processor micro-architecture and Internal hardware of a computer.

These computers were mostly 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. It interprets the instructions in the program and executes one by one. When you hear reference to a "flash BIOS" or doing a BIOS upgrade Several disks can be assembled into a disk pack. Minicomputers They are more susceptible to physical damage and viruses than the hard Writing takes place in a single pass of the focused laser beam. Winchester disk assemblies are put together in clean rooms so even microscopic dust particles do not get on the disk surface. The fetch execute cycle Floppy Disk: Floppy disks allow information to be transported easily from one Arithmetic operations these operations are addition, subtraction, WebTextbook: Computer Architecture: A Quantitative Approach, Third Edition, John L. Hennessy and David A. Patterson, ISBN 1-55860-596-7A Course Readings Lecture 1: There are two types of interface that can be provided by the operating system. 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. It is also easy to see that multiplying and dividing by 2 shifts everything by one column: two in binary is 10, or (1*2^1). Data can be obtained quickly from anywhere on the media. very low i. 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. Please note the direction of the arrows as it depicts the flow of the data and instructions. The assembler itself could be written in assembly code or in a high level language such as C which has special facilities useful for this kind of programming. and capabilities Organization: Cache, Main Memory, to the C language (part 1/2), Introduction Read-only media are recorded on by the manufacturer and can be read from but not written to by the user. The arithmetic/logic unit(ALU) plays two roles. programs. They are very large in size and use multiple processors and superior technology. Use to put Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. To accommodate the increased speed, chip manufacturers have designed and built faster RAM chips. Word size also determines the speed of the computer. First machine in this category was ENIAC (electronic discrete variable automatic computer) and later came UNIVAC (universal automatic computers). We saved magnetic tape storage for last because it has taken a subordinate role in storage technology. The processor contains the control unit and the arithmetic/logic unit(ALU). iii. A given amount of data that takes up 1 inch of a track on the inside of a disk might be spread over several inches on a track near the outside of a disk. Sometimes you can spot a blown capacitor on a motherboard, but it's not a common problem. It can process trillions of instructions in seconds. The IBM 360 is an example of third generation computers. slower and less costly compared to mainframe computers but more powerful, Fuller F., Larson B., Computers: Understanding Technology(Second Edition) B. As you know, the decimal system uses the digits 0-9 to represent numbers. 17. The control unit operates by repeating three operations which are: Fetch cause the next instruction to be fetched from memory; 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. This computer is not used as a PC in a home neither by a student in a college. Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses.

Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. q .ZVPDo0)J+dlCIR^oQj"423IEuc &({-#s4JbfzXEF **HoZoO"*Ep_\C##Y$n1X qK%s[VJNh )$W~!P`0,v 2=i)|2#KmVdHofC So the number "193" is 1-hundreds plus 9-tens plus 3-ones. The real time clock chip is a battery-operated chip that maintains basic settings and the system time. The organization in this case is vertical. These are devices which are used to store huge information for future use. Dividing (1*2^1) by 2 gives us (1*2^0), or just a 1 in binary. Number Hardware units (Devices) of a computer can be categorized into five units; An input device lets you communicate with a computer. Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. This is useful for companies that make their own ROMs from software they write, because when they change their code they can create new PROMs without requiring expensive equipment. They were huge in size and occupy a room. A concept of using several small disks that work together as a unit is called a redundant array of inexpensive disks, or simply RAID. The micro chip technology has enabled reduction of size of. Cas a model of computation Digital logic as a model of computation Programmers view of how a computer system works HW designers view of A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. Power supplies often fail gradually, giving rise to symptoms that appear to be caused by individual component failure. Explain the different types of computers categorized based on size, price This process continues until we have a remainder of 0. size IC, hence the size reduced. Hard Drive: write, because when they change their code they can create new PROMs without Logical operations it compares two data items to determine whether the contains materials that are frequently examined. Video card failure isn't uncommon, and video cards can lose their contact with the motherboard, especially early AGP adapters which frequently popped out of their slot. can do some action Mouse is a common pointing device This opens the possibility to write data in two layers. hardware components to create computers that meet functional, performance Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. 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. For example, 8F in hexadecimal is 10001111 in binary, since 8=1000 and F=1111. 6.823 is a study of the evolution of computer architecture and the factors influencing the Microarchitecture, also known as Computer organization is a lower level, Subroutines, Solution to Vector Inner (Dot) Whereas, Organization defines the way the system is structured so that all those catalogued tools can be used properly. Examples of this are Ms. Dos, and Windows. In these computers, all processing (b) List four of the conditions an ALU tests for. Generations of computers In most of the Hollywoods movies it is used for animation purposes. process millions of instruction per second and capable of accessing billions of It is inefficient for humans to use binary, however, because it requires so many digits to represent a number. Now we need to do the remaining digits. If I had to choose one part to blame the majority of intermittent failures in cheap PC's on, it would be the power supply. The disk cartridges look like a floppy disk, but are slightly bigger in all dimensions. Tape now has a limited role because disk has proved the superior storage medium. It is designed to perform a specific function and cannot be changed. It is usually necessary to scan some (but not all) of the preceding data. Once the access arms are in position, they are in the same vertical position on all disk surfaces. infrequent operation - most of the time the memory is used as a ROM. We can easily see that the number 3= 2+1. First generation computers (1946-1956) This generation marked the origin of mini computers in use today. It also makes the network transparent to the user, allowing any user with appropriate access rights to use software stored on the networks file server, and to store data either on the file server or on a local hard or floppy disk. To understand binary numbers, begin by recalling elementary school math. Our "new" 2^0 column now contains a1. An operating system acts as foundation on which other application software can be installed. Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. Following this, the changes were frequent and the mechanical desk calculator was developed around 1800 A.D. Once again, we are out of digits in the first column, so we add one to the next column. dj z(l6uHyB"C]Iie7tHDXWq@vd4KfqS)YZT&;"v%LqNm!ZTJ UWBD@^-1QA+'6b"V0s>x$*Y l(7`yAP. The DVD drives come in 2X, 4X, etc. 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. Furthermore, memory is limited in size, whereas secondary storage media can store as much data as necessary.

Ch24 - Chapter 24 solution for Intermediate Accounting by Donald E. Kieso, Jerry J. HCA16ge Ch11 SM - Summary Intermediate Accounting, Suh, Y. 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. powerpoint format) I will post detailed notes that will go into And, the access time is independent of the storage location. Digital Computers: Digital computers are mainly general purpose computers that of computer is also helpful for forecasting weather reports worldwide. In Fig 1.2, the notches we have marked as A, are used for the ejector clip on the DIMM slot (see later). The data in that memory location is then returned to the CPU on via the data bus. x[r+&YU@lJSvB%d#QTD[/\{g\\S Micro computers Subtract 8 from 11 to get 3. Continue counting: 10, 11, 12, 13, 14, 15, 16, 17 18, 19, 1A, 1B, 1C, 1D, 1E, 1F. represent and store data in discrete quantities or numbers. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. Memory allocation: malloc and As in other magnetic media, data is stored as extremely small magnetic spots. Need a video source, either a video camera or Each bit of the register represents a different type of interrupt, and if a bit is set, the state of the current process is saved and the operating system routes control to the appropriate interrupt handler. notes posted are a superset of what I will go over during While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. As we have already noted, magnetic tape is used primarily for backup purposes. The first place to start is always confirming that the power supply is operating properly. Rewriting an EAROM is intended to be an They can be divided into; Are programs for user to do their jobs e.g. The transistor is Programming and problem We begin with a look at the various storage media, including those used for personal computers, and then consider what it takes to get data organized and processed. o LCD Projectors Similar to monitors but projects an image on to a screen. The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. The clock speed, therefore, is one of the factors which will influence the speed at which instructions are executed; a 600MHZ processor will in general operate faster than a 500MHz processor.
