Consists of programs that control operations of the computer and enable user to make efficient use of computers. A hard disk is a metal platter coated with magnetic oxide that can be magnetized to represent data. consumed a lot of power and generated a lot of heat (overheating). << /Length 4 0 R /Filter /FlateDecode >> Years later, we learned that the ones column meant 10^0, the tens column meant 10^1, the hundreds column 10^2 and so on, such that. Information is stored in computers in the form of bits. This is also true when reading punched cards or paper tape. Although the user enter data in decimal or character form, it is converted into binary digits Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. vdu controller. A bit is used to represent information in the computer. The micro chip technology has enabled reduction of size of computers. To execute an assembly language program it should first be translates into an equivalent machine language program. 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. For example, the textbook As in other magnetic media, data is stored as extremely small magnetic spots. o Scanner allows you to scan documents, pictures, or graphics and view To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. Compiler, Program For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." interprets the instructions in the program and executes one by one. the micro computers are usually described as PCs or stand alone or desktop computers because they were designed primarily to serve single person at a time. 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. To overcome this limitation, the hexadecimal number system was developed. Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. It is designed to perform a specific function and cannot be peripherals can be attached to them. and data so that it will be very fast to retrieve them again. A different ISR is provided for each different source of interrupt. to the C language (part 1/2), Introduction Data can also be destroyed if a read/write head encounters even minuscule foreign matter on the disk surface. generation saw the introduction of more complex ALU and CPU, the use of high It can process trillions of instructions in Explain the characteristics of computers and how they are different from class. The processor also stores the instructions being currently executed into the main memory. In decimal form, 1+1=2. The sector method is used for diskettes as well as disk packs. A little glass window is installed in the top of the Recording the data vertically, on the other hand, substantially reduces access arm movement. Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. The high level languages commonly used are FORTRAN (FORmula TRANslation), BASIC (Beginner's All-purpose Symbolic Instruction Code), COBOL (COmmon Business Oriented Language). They support concurrent users. A Bus is a set of parallel wires connecting two or more components in a computer. This categories are based on size, price and capabilities. calculations and heavy jobs. Stack and Allocation of C 18-213 18-240. The most prominent optical technology is the CD-ROM, for compact disk read-only memory. Following this, the changes were frequent and the mechanical desk calculator was developed around 1800 A.D. details than what we will cover in the lecture. 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. Assembly language is designed mainly to replace each machine code with and understandable mnemonic code.

We know that: and so on. chip(IC). These are devices which are used to store huge information for future use. 2. Whereas, Organization defines the way the system is structured so that all those catalogued tools can be used properly. the lecture -- the notes posted here provide, in some cases, more Furthermore, data files, particularly those accessed by several users, are subject to errors introduced by users. Let's take a look at how it works. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. SDRAM (Synchronous DRAM) divides RAM into two separate memory banks to increase the processing of the memory requests. Governments specially use this type of computer for their different calculations and heavy jobs. The system unit is the unit that houses the processing unit (processor), memory, the input output controllers and the buses. The control unit operates by repeating three operations which are: Fetch cause the next instruction to be fetched from memory; When you start troubleshooting a dead computer, never ignore the possibility that the AC power to the PC's power supply is at fault. III. This categories are based on size, price and capabilities. A. notes posted are a superset of what I will go over during There is more than one way of physically organizing data on a disk. The speed of these machines was described in milliseconds (1/1000 of a second). An input device lets you communicate with a computer. The micro chip technology has enabled reduction of size of. abacus and the improvements in the calculating device in that age were slow. Microcomputers can be a desktop, laptop, notebooks, or even palmtop. Continue counting: 10, 11, 12, 13, 14, 15, 16, 17 18, 19, 1A, 1B, 1C, 1D, 1E, 1F. A disadvantage of a removable hard disk is that it takes longer to access data than a built-in hard drive. 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. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. Instruction set architecture System organization (processor, memory, I/O) Micro-architecture Learn methods of evaluating performance Metrics Benchmarks Learn how to make systems go fast Pipelining, caching Parallelism Learn how to make systems less power hungry (maybe) It is usually necessary to scan some (but not all) of the preceding data. character recognition (OCR) software is needed Typically, a CD ROM holds up to 650 MB of information. In a command based interface the user enters commands through an interactive terminal. They are used for complex tasks requiring a lot of Now I can imagine even the extra disk filling up.". Large computers have dozens or ever hundreds of disk drives. The decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0). Hard disks come in a variety of sizes. Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? called a mother board. In most of these cases one deals with Data Base Management Systems (DBMS). blueprint and functional description of requirements and design Execute cause the instruction to be executed. FACE RECOGNITION AND SIMILAR, Structure and Interpretation of Computer Programs, TEXTURE ANALYSIS USING SPECTRAL TRANSFORMS. A keyboard, mouse, scanner, digital camera, Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. troubleshooting and upgrading computers. 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.. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. All the processor activities, such as fetching an instruction, reading data into the memory register etc. Record the 0 in the ones column, and carry the 1 to the twos column to get an answer of "10." To provide an in-depth presentation of computer hardware and software with Each disk in the pack has top and bottom surfaces on which to record data. Examples operating systems that use command based interface are Ms Dos and Unix. The normal number system we use is called the decimal or the denary number system. Most disk packs, however, combine the disks, access arms, and read/write heads in a sealed module called a Winchester disk. Secondary storage is necessary because memory, or primary storage, can be used only temporarily.

Every effort will be made to get the notes on the web prior to the lecture. data .They are physically very large in size with very high capacity of main 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." 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. Ch24 - Chapter 24 solution for Intermediate Accounting by Donald E. Kieso, Jerry J. HCA16ge Ch11 SM - Summary Intermediate Accounting, Suh, Y. Once the access arms are in position, they are in the same vertical position on all disk surfaces. Only an interrupt with a higher priority is allowed to interrupt the servicing of another. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. That means that their electronic circuits can exist in only one of two states: on or off. B. The following program written in BASIC language is to add two given numbers. Memory allocation: malloc and notes that you will be expected to read before class. of Maryland. Also it will be very difficult for a person to understand a machine language program written by another person. ROM: A mask programmed read only memory that can be only be produced by the manufacturer. The first calculating device, which was used 2000 years ago was called memory. The number 76, for example, takes only two digits to write in decimal, yet takes seven digits to write in binary (1001100). The first in the Windows series was Windows 3.11 and the latest being Windows Vista. The technology works like this: A laser hits a layer of metallic material spread over the surface of a disk. lecture notes available from the. within a computing system such as: Objectives 2kb and speed of processing was also very low. 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.) Use to put WebComputer Architecture - Class notes. They used magnetic tape. and cost goals. Neumann Architecture Model and The processor and main memory of a PC are commonly held on a single board 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. Hardware: input and output devices, backup storage, central processing The basic functions of an operating system are; A stand a lone operating system controls a single computer that is not connected to others on a network. To visualize cylinder organization, pretend a cylindrically shaped item, such as a tin can, were figuratively dropped straight down through all the disks in the disk pack. Then we just put this into columns. seconds. The binary number system is a method of storing ordinary numbers such as 42 or 365 as patterns of 1's and 0's. Logical operations it compares two data items to determine whether the Peripheral Component Interconnect (PCI)-connections for video, sound and, video capture cards, as well as network cards, Integrated Drive Electronics (IDE) -interfaces for the hard drives. 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). chapters. The disk in its drive is shown in Figure 3. D. Hard Drive Failure Troubleshooting, V. Input and output devices and interrupts. This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. In 1833, Prof. Charles Babbage, the father of the computer, developed a machine called analytical engine which was the vase for the modern digital computer. The group of connected disks operates as if it were just one large disk, but it speeds up reading and writing by having multiple access paths. Computers have continued to decrease in size but the processing power has Next, we focus specifically on the CPU (Central Processing Unit). A program must tell the computer each of a set of tasks to perform, in a framework of logic, such that the computer knows exactly what to do and when to do it. They are expensive to install. Computer architecture or digital computer organization is the conceptual design and fundamental operational structure of a computer system. 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. multiple processor system with parallel processing. very low i. They are smaller than the main frame but bigger than microcomputers. o Number of components in computer per circuit (IC) greatly increased over They can be used as servers in companies. Need a video source, either a video camera or In the sector method each track is divided into sectors that hold a specific number of characters. interoperate in order to implement the ISA. The CPU of a The 3-1/2 inch diskette has the protection of a hard plastic jacket, a size to fit conveniently in a shirt pocket or purse, and. Dividing (1*2^1) by 2 gives us (1*2^0), or just a 1 in binary. scan. It has a grid of columns and rows with a cell that has two transistors at each intersection. Need sound recording DVD movies are made in two "codes." So can be able to read and write into the main memory (RAM). works by letting you "burn" programs onto blanks once and then letting you History of computers This demanding shopping list is a description of the optical disk, like a CD. Examples: What would the binary number 1011 be in decimal notation? give the user output P&H: Computer Organization & Design, by Patterson and Hennessy. Inside the computer The purpose is to reduce the time it takes to move the access arms of a disk pack into position. Record the 1. When buying a computer the speed of the CD-ROM drive is advertised using an "X" factor, like 12X, or 24X. Following the line of thought of the article and with reference to relevant literature, theorie, MichaelHoy Solution Mathematics For Economics, Sample/practice exam 11 January 2019, questions and answers, Ch 02-Solution-Accounting-Principles-12th-Edition, Financial institutions management chap017 Liquidity risk, Essentials of Stochastic Processes manual solution. processing. MCA, or the Micro Channel bus, was a competition for ISA bus. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. To multiply by two, just add a 0 on the end. Video Failure Troubleshooting They coordinate computer activities and optimize use of computers. Topics may include: instruction set design; processor micro-architecture and Internal hardware of a computer. (Photo openphoto.net. Used with permission.) Intel Core i3, i5 and i7 are 1.2 GHz to 3.33 GHz, 1.06 GHz to 3.6 GHz and 1.06 GHz to 3.46 GHz, respectively. Ultraviolet light of a specific frequency can be shined through this window for a specified period of time, which will erase the EPROM and allow it to be reprogrammed again. o Microphone Used to put sound into a computer. 2kb and speed of processing was also very low. Word size means the number of Bits that the processor can process simultaneously. 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. solving constructs, Assembly HARDWARE DESIGN OF DSP PROCESSORS IN FPGA. A. 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 fetch execute cycle 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 appreciate this, suppose you had an empty disk pack on which you wished to record data. written and quite useful -- they were written by the instructor for The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. A single bit alone cannot represent a number, letters or special characters, to represent information; bits are combined into groups of eight. 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. What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? read from them many times. Take a look at the images below on the right, as you can see, we have pointed out certain parts of the DIMM memory module and the DIMM slot. II. A typical data bus consists of 8, 16, or separate lines. The movies are made in two formats, each with their own coding. For personal computer users, an easy and inexpensive way to back up a hard disk file is to simply copy it to a diskette whenever it is updated. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? computers are mainly used for scientific and engineering applications. A set of programs associated with the operation of a computer. slower and less costly compared to mainframe computers but more powerful, Furthermore, memory is limited in size, whereas secondary storage media can store as much data as necessary. A byte can hold 28 different combinations of 0s and 1s, which means that for example, 256 different characters can be represented. Each peripheral device operates in a different way and hence these devices cannot be connected directly to the processor. Organization: Cache, Main Memory, using special equipment (a PROM programmer. digital computers. the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. You can also use software to edit the items you can do some action Mouse is a common pointing device Hard disks for personal computers are 5-1/4 inch or 3-1/2 inch disks in sealed modules and even gigabytes are not unusual. The second A large number of peripherals can be attached to them. 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. to the C language (part 2/2), Run-time Power Supply Troubleshooting This is inflexible and so regular ROMs are only used generally for Different industries also use this huge computer for designing their products. They made use of vacuum tubes to store and process information. The speed of these machines was described in milliseconds (1/1000 of a second), Second generation computers (1957-1967) Many cheaper PC's ship with power supplies I would basically describe as "disposable." the maim memory, and works by storing the most frequently or recently used instructions II. In our vertical notation. DVD disks are read by a laser beam of shorter wave-length than used by the CD ROM drives. Super computers are biggest in size, the most expensive in price than any other is stream devices. Practically, we can simply keep a "running total", which now stands at 11 (a[1]=1 and a[0]=1). the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. 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 lithium battery. {HnzIxfjw^K](^$L The control unit operates by repeating three operations which are: The cycle (input -processing -output) would not be possible without a holding place for the instructions and data that the processors (CPU) can easily reach. The address bus is used for communicating the physical addresses of computer memory elements/locations that the requesting unit wants to access (read/write). Since 0011=3 and 0101=5, the corresponding hexadecimal number is 35. http://www.math.grin.edu/~rebelsky/Courses/152/97F/Readings/student-binary, Answers 1 255 2. a) 3 b) 6 3. a) 110010 4. a) 1011 5 a) 13, c) 10 d) 65 b) 1001011 d) 1000011c) 11111010. These computers used transistors after invention of transistors. A large number 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 The IBM 360 is an example of third generation computers. ()Microarchitecture, also known as Computer organization is a lower level, more concrete and detailed, description of the system that involves how the constituent parts of the system are interconnected and how they interoperate in order to implement the ISA. Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. Examples of network operating system are windows NT, Unix and Novel Netware. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. They are of advanced technology i.e. This is useful for companies that make their own ROMs from software they The read/write head on the end of the access arm hovers just above the track but does not actually touch the surface. changed. For example, putting ten in the 10^0 column is impossible, so we put a 1 in the 10^1 column, and a 0 in the 10^0 column, thus using two columns. does not cover memory design in any depth and I will provide detailed more emphasis on the more technical aspects of computing such as Minicomputers 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. At the end of the chapter the learner shall be able to; many applications, EAROM has been supplanted by CMOS RAM backed-up by Removable units also are important to businesses concerned with security, because the units can be used during business hours but hidden away during off hours. (a) Supercomputers (b) Mainframe (c) Mini computer (d) Micro computer. where each a[i] is either a 1 or a 0 (the only possible digits for the binary system). Icons represent programs, groups of programs, folders, devices and files. These computers had programming languages whose vocabularies are close to the human natural language, English language. B. A motherboard allows all the parts of your computer to receive power and communicate with one another. The largest power of 2 in 11 is 8, or 2^3. Starting from zero, we count 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F. At this point there are no more digits, so we add another column. The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. Alternatives such as Zip disks (discussed later), or transferring data via networks are making the low-capacity diskette become obsolete. software. Furthermore, as we will see, disk data can be accessed directly, as opposed to data on tape, which can be accessed only by passing by all the data ahead of it on the tape. Disk data is quite reliable, especially within a sealed module. Lecture 21 (TBS): write, because when they change their code they can create new PROMs without 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. This is the most flexible type of ROM, and is now commonly used for holding BIOS programs. notes posted are not meant to substitute for the text Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a Video failure can also be due to motherboard failure or to external interference, when it comes to poor image quality. Temporary Result: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. size though today the term is used to refer to large computers. To provide an in-depth presentation of computer hardware and software with more emphasis on the more technical aspects of computing such as troubleshooting and upgrading computers. Random-access storage media refers to magnetic core, semiconductor, thin film, and bubble storage. keyboard controller or as output controller, e.g. However, this is not the only approach possible. 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. Interrupts are therefore assigned priorities so that when two interrupts are received simultaneously, the one with the highest priority is dealt with first. power. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. variables, Implementation of functions, Dynamic AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j The record storage rooms would have to be enormous. 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. Control lines are used to ensure that access to and use of the data and address buses by the different components of the system does not lead to conflict. Number Many cartridges and cassettes have the supply and take-up reels built into the same case. Since we already knew how to convert from binary to decimal, we can easily verify our result. 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). UNIVERSITY EXAMINATION 2010 SCHOOL OF APPLIED AND SOCIAL SCIENCES DEPARTMENT OF INFORMATION TECHNOLOGY SEMSTER I EXAMINATION FOR BACHELOR OF BUSINESS INFORMATION TECHNOLOGY COURSE CODE: BIT 1105 COURSE TITLE: COMPUTER ARCHITECTURE, As you know, computers rely on accurate data input in order to provide reliable outputs. to do something, like save the file. A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. 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. and to perform computations on these measurements. They are slower and less costly compared to mainframe computers but more powerful, reliable and expensive than micro computers. Commands tell the computer Continuing the "CD" analogy, this technology is analogous to a reusable CD-RW.
