computer architecture ppt lecture notes

They were huge in size and occupy a room. for instance, is an organizational issue that generally has nothing to do Only an interrupt with a higher priority is allowed to interrupt the servicing of another. In effect, a removable cartridge is as portable as a diskette, but the disk cartridge holds much more data. Micro computers They used magnetic tape. With any method of data storage, a backup system a way of storing data in more than one place to protect it from damage and errors is vital. A set of programs associated with the operation of a computer. increased. When you hear reference to a "flash BIOS" or doing a BIOS upgrade The notches we have marked as B, are used to align the memory module with the DIMM slot keys C, as shown in Fig 1.3. WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. This generation marked the origin of mini computers in use today. (a) Vacuum tubes (b) Capacitors (c) Transistors (d) Integrated circuits, Which one of the following types of computers is commonly used in offices The outer gold layer is semi transparent, to allow reading of the underlying silver layer. To execute an assembly language program it should first be translates into an equivalent machine language program. The CPU and the RAM are two main components that can be upgraded to increase a computer's speed, though doing this may require replacing the motherboard as well. DVD movies are made in two "codes."

Kurose,W. In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. Email: info@mku.ac Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. j!)+v%""s!-+ 2MYI9RVgJm +9 vy?nW?n%}GQdd Ny= z-I9GZI3)hKrhIY$W. They are referred to as binary digits i.e. written and quite useful -- they were written by the instructor for Eight's column: We can divide by two again to get 20. Almost all the computers used nowadays are digital computers and we will Invention of IC revolutionalised electronics and started the error of micro-electronics. Storage capacity was drive. With IC you can house thousands of transistors in one IC. List three common input devices (excluding keyboard and mouse), giving one advantage and one disadvantage for each, together with an example of how each could be used in the retail industry. We're left with 1, which goes in 2^0, and we subtract one to get zero. 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. 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. of Maryland. hardware components to create computers that meet functional, performance The EISA bus is found on Intel 80386, 80486 and early Pentium computers. o Video Capture Card Usually place inside the computer's case. You might be tempted to record the data horizontally-to start with the first surface, fill track 000, then fill track 001, track 002, and so on, and then move to the second surface and again fill tracks 000, 001, 002, and so forth. Obviously this is much more useful than a regular 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). The processor communicates and controls a peripheral device through an I/O or device controller. For A. If you are sharing your computer, you must yield memory to someone else after your program runs; if you are not sharing your computer, your programs and data will disappear from memory when you turn off the computer. The control unit operates by repeating three operations which are: Fetch cause the next instruction to be fetched from memory; peripherals can be attached to them. Particularly step 3, "filling in the zeros." The records are read in sequence. Purpose of the course This is a technology that allows a computer to immediately locate and retrieve a program, information or data. with the ISA. 2 0 obj ci Ny&V3Otu1gz=} -`iA2(]^,{X+b'Md90sob^V}+^LgaCt4'USr?idz}KiLn[!e8$-$+O;7m%z1+$9]ZumJxC|h$? The organization in this case is vertical. general purpose software, integrated packages and software suites. Since these programs use only '0's and '1's it will be very difficult for developing programs for complex problem solving. Commands tell the computer In most of these cases one deals with Data Base Management Systems (DBMS). Since Assembly language is machine dependent each type of computer has its own assembler. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. A 4.7 GB side of a DVD can hold 135 minutes top quality video with 6 track stereo. The take-up reel always stays with the magnetic tape unit. The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge. Binary addition works on the same principle, but the numerals are different. Therefore, there must be a 0 in the 4's column, (because what we are actually placing is a 2^0 column, and the number is not odd). When you remove the DIMM memory module from its packaging hold it by the edges, try not to touch the gold coloured contacts, as this can damage the memory. They are very large in size and use multiple processors and superior technology. Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. first one is smaller than, equal to or greater than the second item. Furthermore, data files, particularly those accessed by several users, are subject to errors introduced by users. Hardware and software They coordinate computer activities and optimize use of computers. It can process trillions of instructions in seconds. notes posted are a superset of what I will go over during powerpoint format) I will post detailed notes that will go into Nguyen Quoc Trung. Applications of 4GL's are concentrating on the daily performed tasks such as screen forms, requests for data, change data, and making hard copies. There are three types of program that can translate programming code into machine understandable form (machine code). Electrically Erasable Programmable ROM (EEPROM): The next level of erasability is the EEPROM, which can be erased under software control. technology is analogous to a reusable CD-RW. For the sake of simplicity, throw away the remainder. The code written by the programmer is called the source code and the compiled code is called the object code. Perhaps more important than capacity, however, is the convenience of speed. gigabytes. multiple processor system with parallel processing.

(d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? NB: Nowadays most of the general purpose software is being sold as a complete software suites such as Microsoft office or Lotus SmartSuite. It is the main part of a computer system like the brain of a human being.

The processor has the following functions: It controls the transmission of data from input devices to memory; It processes the data held in main memory; It controls the transmission of information from main memory to output Research shows that the trend in computer technology revolution is that there is; A computer is an electronic device capable of executing instructions, developed based on algorithms stored in its memory, to process data fed to it and produce the required results faster than human beings. 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. The width of an address bus, along with the size of addressable memory elements, determines how much memory can be accessed. A disk pack has a series of access arms that slip in between the disks in the pack. iii. A motherboard by itself is useless, but a computer has to have one to operate. The object code contains information not only on the instructions given by the programmer but also instruction for the computer about memory allocation and references towards external locations and sub routines (libraries). Here, a given item of data can be selected from anywhere in storage without having to scan any preceding items. The explosive growth in storage needs has driven the computer industry to provide cheaper, more compact, and more versatile storage devices with greater capacity.

It acts as an intermediate store between the CPU and the maim memory, and works by storing the most frequently or recently used instructions and data so that it will be very fast to retrieve them again. The processor also stores the instructions being currently executed into the main memory. Super computers are biggest in size, the most expensive in price than any other is classified and known as super computer. The form factor affects where individual components go and the shape of the computer's case. Tapes come in a number of forms, including l/2-inch-wide tape wound on a reel, l/4-inch-wide tape in data cartridges and cassettes, and tapes that look like ordinary music cassettes but are designed to store data instead of music. It is inefficient for humans to use binary, however, because it requires so many digits to represent a number. The record storage rooms would have to be enormous.

Hybrid Computers: Hybrid computers incorporate the technology of both analog and analogous to a commercial software CD-ROM that you purchase in a store. Although a hard disk is an extremely reliable device, a hard disk drive is subject to electromechanical failures that cause loss of data. The OS controls who logs on to the network by means of user names and passwords, in order to protect the data and programs stored on the network. software program. At present, computer users do not write programs using machine language. A disk drive is a machine that allows data to be read from a disk or written on a disk. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. Microcomputers can be a desktop, laptop, notebooks, or even palmtop. Fuller F., Larson B., Computers: Understanding Technology(Second Edition) 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. It is used more like a ()hard drive than as ()RAM. the lecture -- the notes posted here provide, in some cases, more Magnetic disks and drums are examples of direct-access storage media. 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." To multiply by two, just add a 0 on the end. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. They A computer has to main components; 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. Several disks can be assembled into a disk pack. them on the computer. The CPU is connected to the main memory by three separate buses. and that this is equivalent to (1*2^1)+(1*2^0). The main features which distinguish one processor from another and which determine the performance of each are; In addition the CPU contains circuitry controlling the interpretation and execution of instructions. computational power. Try converting these numbers from binary to decimal: | | | 1 | 0 | | 1 | 1 | 1 1 | 0 | 1 | 0 | 1 1 | 1 | 1 | 1 | 0. Examples operating systems that use command based interface are Ms Dos and Unix. -- you are required to read the textbook before (and after) each class. Computer System Architecture Lecture Notes PDF Free Download Computer Science Engineering. Representations -- Datatypes and For example, to convert 110101 to hexadecimal, first add two zeros at the beginning of the number to make it 00110101. contains materials that are frequently examined. Examples of this are Ms. Dos, and Windows. Compact Disk-Writable (CD-R): A CD-R is highly effective for storing a large amount of data. Input Devices Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." South bridge -Refers to the Peripheral Bus Controller component of a Pentium chipset, responsible for implementing a PCI-to-ISA bridge function and for managing the ISA bus and all the ports. troubleshooting and upgrading computers. DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. The first in the Windows series was Windows 3.11 and the latest being Windows Vista. must begin on a clock pulse, although some activities take more than one clock pulse to complete. devices. interoperate in order to implement the ISA. Chapter Objectives At the end of the chapter the learner shall be able to; Internal components are contained in the System Unit. Also these programs written for execution in one computer cannot be used on another type of computer. Optimization, Memory Subtract 8 from 11 to get 3. seconds. taken by a digital camera can be used directly by a computer contains materials that are frequently examined. This places the data in diagonal bands that run across the tape rather than down its length. There are two types of interface that can be provided by the operating system. These are devices which are used to store huge information for future use. )fb1{`BF Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. Saving and retrieving information from a floppy disk is slower than on a hard drive. college. generation saw the introduction of more complex ALU and CPU, the use of high Need sound recording Computer software As you know, the decimal system uses the digits 0-9 to represent numbers. They are In most of the Hollywoods movies it is used for animation purposes. In the sector method each track is divided into sectors that hold a specific number of characters. Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. For example, "3" in binary cannot be put into one column. 9 The DVD is a flat disk, the size of a CD -4.7 inches diameter and .05 inches thick. 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. A keyboard, mouse, scanner, digital camera, o Keyboard Used to type data into the computer. computer. Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. MCA, or the Micro Channel bus, was a competition for ISA bus. works by letting you "burn" programs onto blanks once and then letting you Chapter 1- Fundamentals of Computer Design. Fourth GL Programming languages are closer to human languages than typical high-level programming languages. Dividing (1*2^1) by 2 gives us (1*2^0), or just a 1 in binary. Each peripheral device operates in a different way and hence these devices cannot be connected directly to the processor. Let's take a look at how it works. Since 2222=16, this means that each hexadecimal digit is worth exactly four binary digits. The second To appreciate this, suppose you had an empty disk pack on which you wished to record data. Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. 2kb and speed of processing was also very low. Diskettes became popular along with the personal computer. Here we are blurring the line a bit between what "read-only" really means, but remember that this rewriting is done maybe once a year or so, compared to real read-write memory (RAM) where rewriting is done often many times per second! Our "new" 2^0 column now contains a1. Use to put Zip disks are a great way to store large files and software programs. video into a computer. This is also true when reading punched cards or paper tape. 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. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine The lecture WebCS385 Computer Architecture, Lecture 1 Reading: Patterson & Hennessy - Chapter 1 Topics: Introduction, Computer Architecture = Instruction Set Architecture + Machine You will see that it is the same procedure, but with sixteen digits instead of 10 or 2. Different industries also use this huge computer for It is the smallest of the three computers. All 4GLs are designed to reduce programming effort, the time it takes to develop software, and the cost of software development. Take the number 163. A bit is used to represent information in the computer. A keyboard, mouse, scanner, digital camera, touch pads and joystick are examples of input devices. Arithmetic operations these operations are addition, subtraction, These computers were mostly computational machines. Diskettes offer particular advantages which, as you will see, are not readily available with hard disk: The end of the diskettes useful life-time may be upon us. These two "bridges" connect the CPU to other parts of the computer. Programmable ROM (PROM): This is a type of ROM that can be programmed using special equipment (a PROM programmer. The speed of these machines was described in milliseconds (1/1000 of a second). In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. software 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." A large number of peripherals can be attached to them. Software is simply set of instructions that cause a computer to perform one or more tasks. system that is seen by a machine language (or assembly language) Windows is a Graphical user interface based operating system. A rule of thumb among computer professionals is to estimate disk needs generously and then double that amount. within a computing system such as: Objectives In such a system a task is broken down and shared among processes Each disk in the pack has top and bottom surfaces on which to record data.
