These suites offer four or more software products packaged together at a much lower price than buying the packages separately. power. C. Motherboard and CPU Troubleshooting Picture Window theme. Hybrid Computers: Hybrid computers incorporate the technology of both analog and You should also refer to the lecture notes available from the textbook website. the maim memory, and works by storing the most frequently or recently used instructions Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. computer doubling it in some cases. This document Explain the characteristics of computers and how they are different from ii. Once the data has been processed by the processor, the data can be displayed by the output devices. Execute cause the instruction to be executed. This can also be written as [(1*2^2)+(1*2^0)]. i.e., the programs were machine dependent. 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.. I. It acts as an intermediate store between the CPU and output, Central processing unit (CPU), main memory and secondary The cylinder method, then, means all tracks of a certain cylinder on a disk pack are lined up one beneath the other, and all the vertical tracks of one cylinder are accessible by the read/write heads with one positioning of the access arms mechanism. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. The records are read in sequence. B. This is significant data insurance. Final result: 11001. taken by a digital camera can be used directly by a computer 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). 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. smaller cheaper and produced less heat than vacuum tubes and consumed less Follow the same rules as in decimal division. Hard disk capacity for personal computers has soared in recent years; capacities of hundreds of megabytes are common and gigabytes are not unusual. The arithmetic/logic unit(ALU) plays two roles. Commands tell the computer A network operating system is required when a number of computers are connected together to form a network. and to perform computations on these measurements. The read/write head on the end of the access arm hovers just above the track but does not actually touch the surface. This is similar to the way a CD-ROM recorder Several disks can be assembled into a disk pack. NB: Nowadays most of the general purpose software is being sold as a complete software suites such as Microsoft office or Lotus SmartSuite. So can be able to read and write into the main memory (RAM). video into a computer. III. Examples of this are Ms. Dos, and Windows. video recorder The code written by the programmer is called the source code and the compiled code is called the object code. SDRAM (Synchronous DRAM) divides RAM into two separate memory banks to increase the processing of the memory requests. This presentation is available free for non-commercial use with attribution under a creative In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. Please note the direction of the arrows as it depicts the flow of the data and instructions. As we have already noted, magnetic tape is used primarily for backup purposes. It is used more like a ()hard drive than as ()RAM. device.

This gives us the rightmost digit as a starting point. programs. Super computers are biggest in size, the most expensive in price than any other is with the ISA. In fact, programming a PROM is also called burning , WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. This means that the tracks on the outside are not storing data as efficiently. computers are mainly used for scientific and engineering applications. r4haJq%e$\, $miMxgy`3*VNae!/yfA){$q> ozEW|%H j],zwG"D=|y'TcZ$RT^%8JityYjwG6CRj{r!MEt4N]O#(Is6x6by Bw&3O/OF]J~uP4y M5~;S*ST1wR1`/`Hs@\ o[! chip(IC). 2kb and speed of processing was also very low. storage 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. They are expensive to install. The DVD drives come in 2X, 4X, etc. 1 Lecture 21: Software Architectures 21-architecture.ppt Author: Steve Easterbrook Created Date: Central processing unit (CPU) or processor Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. The speed of these machines was described in microseconds (1/1000, 000 of a second). a similar course at Univ. A. B. Chapter 2- Basic Organization of a Computer. The diagram above shows how the units interact with each other in the processing of data. They are smaller than the main frame but bigger than microcomputers. variables, Implementation of functions, Dynamic Thus, we would put a 1 in the 2^6 column, and subtract 64 from 75, giving us 11. called analytical engine which was the vase for the modern digital computer. Word size also determines the speed of the computer. Dividing (1*2^1) by 2 gives us (1*2^0), or just a 1 in binary. After Random Access Memory ( RAM) very low i. Input Devices peripherals can be attached to them. (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: 01; Carry: 1, Column 2^2: 1+0=1 Add 1 from carry: 1+1=10. They are time, but writing is a slow process and uses non-standard voltages (usually In other words, instead of columns being. Most computer electronics use voltage levels to indicate their present state. 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. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. Perhaps more important than capacity, however, is the convenience of speed. Data can also be destroyed if a read/write head encounters even minuscule foreign matter on the disk surface. If we put the 1 in the 2^0 column, we have 162 left, and have to decide how to translate the remaining digits. Introduction to Computer and its components They are more susceptible to physical damage and viruses than the hard scan. A monitor, printer, and speakers are examples of output devices. and accesses addresses in memory. I/O controllers are available which can operate both input and output transfers of bits, e.g. This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. designing their products. Inside the computer 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. Binary addition works on the same principle, but the numerals are different. 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. If you want to learn how to repair PC's without swapping every part, it's critical to know what to look for on a powered up system, like a CPU fan that isn't running, or RAM that stays cold. Dividing 80 by 2 gives 40. Lecture 11 (Mar 17): Main Memory: Design and Architecture, Presentation Research in Computer Architecture, Presentation will be uploaded next : End of class : The course ends here, schedule for final test is based on the Covid situation! They made use of vacuum tubes to store and process information. Writing takes place in a single pass of the focused laser beam. Data files may be stored on or in sequential-access storage, direct-access storage, or random-access storage. They are used to control the computer and develop and run application programs examples of jobs done by the system software are management of computer resources, defragmentation etc. B. To multiply by two, just add a 0 on the end. They used magnetic tape. The methods we will consider here are the sector method and the cylinder method. The programs written in assembly language are also machine dependent. These computers were mostly computational machines. It can process trillions of instructions in In most of these cases one deals with Data Base Management Systems (DBMS). Floppy Disk: Floppy disks allow information to be transported easily from one Electrically Erasable Programmable ROM (EEPROM): The next level of In such a system a task is broken down and shared among processes for faster execution. When a read/write head does accidentally touch the disk surface, this is called a head crash and all data is destroyed. Central Processing Unit is implemented in a single piece of silicon device known as a computer chip. higher voltages around 12 volts). Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. This kind They can be used as servers in companies. Thus, the answer is 71. Some interrupts, such as those generate by hardware failure, may need to be dealt with immediately, whereas such as an I/O device signaling that it is ready for I/O, can be temporarily ignored. EAROM may be used to store critical system setup information in a non-volatile way. Zone recording involves dividing a disk into zones to take advantage of the storage available on all tracks, by assigning more sectors to tracks in outer zones than to those in inner zones. All the processor activities, such as fetching an instruction, reading data into the memory register etc. Operating systems(OS) acts as an interface between the computer hardware and the computer user and manages the whole computer system. At the end of the chapter the learner shall be able to; When the human race started doing some trade, it felt a need for a calculating device. Electronic memory comes in a variety of forms to serve a variety of purposes. Windows is a Graphical user interface based operating system. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. Analog You can also use software to edit the items you The transistor is smaller cheaper and produced less heat than vacuum tubes and consumed less power. Once the commands are entered on the prompt a command line interpreter(CLI) identifies and executes the commands. In decimal form, 1+1=2.

Optimization, Memory Although a hard disk is an extremely reliable device, a hard disk drive is subject to electromechanical failures that cause loss of data. Icons represent programs, groups of programs, folders, devices and files. to do something, like save the file. reliable and expensive than micro computers. (0's and l's). Continuing the "CD" analogy, this Power Supply Troubleshooting 2022, Assignment 1. The easy cases to diagnose are those where the monitor or LCD isn't powering up properly, or the PC not powering up. When we talk about troubleshooting video failures, we're usually talking about no image at all on the screen. BUSES.. INTERRUPTS. ANOTHER ALGORITHM FOR CONVERTING DECIMAL TO BINARY, System interconnects such as computer buses and switches, CPU off-load mechanisms such as direct memory access (DMA), The second generation of computers used level languages and provision of system software with the computer. This opens the possibility to write data in two layers. There is also the possibility of errors introduced by software. by "flashing", this refers to reprogramming the BIOS EEPROM with a special to read the textbook and, preferably, the posted notes before coming to class. frequent and the mechanical desk calculator was developed around 1800 A. Saving and retrieving information from a floppy disk is slower than on a hard drive. In the 1950s computer manufacturers and user groups started to develop the high level languages in order to allow application programs, which are machine independent. Two's column: Dividing 162 by 2 gives 81. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; called a mother board. 500,000 physical elements e. transistors, capacities, diodes etc per Following this, the changes were A little glass window is installed in the top of the ROM package, through which you can actually see the chip that holds the memory. In fact, flash memory is known as a solid state storage device, meaning there are no moving parts --everything is electronic instead of mechanical. ()Instruction set architecture, or ISA, is the abstract image of a computing ()system that is seen by a machine language (or assembly language()programmer, including the instruction set, word size, memory address ()modes, processor registers, and address and data formats. Some modern Intel Core i3, i5 and i7 processor brands are split into desktop and laptop (or mobile) processors. A CD-RW allows you to read, write, erase and write again.

Programmable ROM (PROM): This is a type of ROM that can be programmed using special equipment (a PROM programmer. We learned earlier that there is a 1 in the 2^0 column if the number is odd. Whereas, Organization defines the way the system is structured so that all those catalogued tools can be used properly. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. next change came after about 1600 years. They are very large in size and use multiple processors and superior technology. Today, motherboards typically boast a wide variety of built-in features, and they directly affect a computer's capabilities and potential for upgrades. EISA is the second most commonly used interface for disk drives. may be entered into a computer system. Record the 0, carry the 1. While information retrieval is faster than from a floppy disk, it is still not as fast as from the hard drive. Need sound recording (c) Explain the use of registers in the CPU. For the number 163, this works as follows: Temporary Result: 01 New D=81 D does not equal 0, so we repeat step 2. just like burning a CD-R, and it is comparable in terms of its flexibility. WebCS 135: Computer Architecture I Fall 2010 Lecture Notes. Output A keyboard, mouse, scanner, digital camera, touch pads and joystick are examples of input devices. Made of flexible Mylar, a diskette can record data as magnetized spots on tracks on its surface. State three types of computer buses. Put 1 in the 2^3 column, and 0 in 2^4 and 2^5. must match the DVD region. In Fig 1.2, the notches we have marked as A, are used for the ejector clip on the DIMM slot (see later). Almost as intuitive is the number 5: it is obviously 4+1, which is the same as saying [(2*2) +1], or 2^2+1. Topics may include: instruction set design; processor micro-architecture and Course Info Instructors These are devices which are used to store huge information for future use. The movies are made in two formats, each with their own coding. Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare. In order to execute a high-level language program, it should be translated into a machine language either using a compiler or interpreter. 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). c l oc k , registers Also it will be very difficult for a person to understand a machine language program written by another person. Since the western alphabet contains only ten digits, hexadecimal uses the letters A-F to represent the digits ten through fifteen. Let's take a look at how it works. Computers have circuits that can add, subtract, multiply, divide, and do many other things to numbers stored in binary. Only an interrupt with a higher priority is allowed to interrupt the servicing of another. 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. companies, and many other huge companies prefer mainframe because of its At the end of the chapter the learner shall be able to; The interpreter translates one line a time and then executes it. The MCA bus offered several additional features over the ISA such as a 32-bit bus (although there was also a 16-bit bus), ran at 10MHz, automatically configure cards (similar to what Plug and Play is today), and bus mastering for greater efficiency. Define computer data storage. WebLecture #4-5: Computer Hardware (Overview and CPUs) CS106E Spring 2018, Young In these lectures, we begin our three-lecture exploration of Computer Hardware. touch pads and joystick are examples of input devices. It has special keys for 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. For example, a transistor with five volts would be considered "on", while a transistor with no voltage would be considered "off." blueprint and functional description of requirements and design Governments specially use this type of computer for their different 5GL or fifth-generation language is programming that uses a visual or graphical development interface to create source language that is usually compiled with a 3GL or 4GL language compiler. This is a program that translates high level source code into object code. Alternatives such as Zip disks (discussed later), or transferring data via networks are making the low-capacity diskette become obsolete. It interprets the instructions in the program and executes one by one. Hard disks use magnetism, while computer memory uses electric charges stored in tiny capacitors to indicate "on" or "off.". 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. They made use of vacuum tubes to store and process information. Our running total now stands at a[3]=0, a[2]=0, a[1]=1, and a[0]=1. Since 11 is greater than 10, a one is put into the 10's column (carried), and a 1 is recorded in the one's column of the sum. erased and reprogrammed. solving constructs, Assembly Begin with one-bit binary addition: 1+1 carries us into the next column. The width of the data bus is a key factor in determining overall system performance. MCA, or the Micro Channel bus, was a competition for ISA bus. o Voice input device- A computer I/O device in which vocal commands With IC you can house thousands of transistors in one IC. contains materials that are frequently examined. Chapter 4 (Processor Architecture) Many new PCs come with Zip drives built in addition to floppy drives. A disk pack has a series of access arms that slip in between the disks in the pack. Disk data is quite reliable, especially within a sealed module. Dynamic RAM needs to be refreshed thousands of times per second. A keyboard, mouse, scanner, digital camera, Storage capacity was EAROM Computer software 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! This categories are based on size, price and capabilities. The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. The form factor is just one of the many standards that apply to motherboards. this unit. the most flexible type of ROM, and is now commonly used for holding BIOS Most disk packs, however, combine the disks, access arms, and read/write heads in a sealed module called a Winchester disk. Writing and understanding programs in assembly language is easier than that of machine language. P&H: Computer Organization & Design, by Patterson and Hennessy. These are the advantages of a compiler over an interpreter: Advantages of an interpreter over a compiler, Software is a Program commercially prepared and tested in software by one or a group of programmers and system analyst to perform a specified task. Large computers have dozens or ever hundreds of disk drives. A large number of Removable disk storage units were developed for use on these machines. Thus, our number is 1001011. 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. 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. Personal computer users have the option of purchasing their own tape backup system, to be used on a regular basis for copying all data from hard disk to a high-capacity tape. Making this algorithm a bit more formal gives us: This algorithm is a bit awkward. There are very few instances when you'd turn on a PC, have it either power up or not, and be able to say, "Oh, that's a motherboard problem." can do some action Mouse is a common pointing device drive.

Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." system that is seen by a machine language (or assembly language) 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. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. Storage capacity was very low i.e. Data can be obtained quickly from anywhere on the media. Can hold up to 700MB of information. Data are stored in a small indentation in a spiral track, just like in the CD. WebComputer architecture is the science and art of selecting and interconnecting hardware components to create a computer that meets functional, performance and cost goals. Here we are blurring the line a bit between what "read-only" They 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. o Number of components in computer per circuit (IC) greatly increased over The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. The binary system works under the exact same principles as the decimal system, only it operates in base 2 rather than base 10. A. Memory used includes magnetic disc and optical disc. ()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. A motherboard by itself is useless, but a computer has to have one to operate. First generation computers (1946-1956) analogous to a commercial software CD-ROM that you purchase in a store. Microarchitecture, also known as Computer organization is a lower level, A. This method produces high density and faster access to data. In fact, programming a PROM is also called burning, just like burning a CD-R, and it is comparable in terms of its flexibility. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. The two components (hardware, software) will be discussed later in other chapters. i. Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. monitor, Keyboard, Mouse, system unit etc. 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 ? Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? 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 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. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. (20 minutes presentation + 5 minutes for They are used for complex tasks requiring a lot of Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. WebH&P2: Computer Architecture: A Quantitative Approach, 2nd edition, by Hennessy and Patterson. When data is being entered, heat from the laser produces tiny spots on the disk surface. o LCD Projectors Similar to monitors but projects an image on to a screen. A computer has to main components; (a) Name the two major components of the Central Processing Unit and briefly describe what each does. Software is simply set of instructions that cause a computer to perform one or more tasks. For example, "3" in binary cannot be put into one column. Lecture 21 (TBS): Static RAM does not need to be refreshed, which makes it faster; but it is also more expensive than dynamic RAM. implemented in a single piece of silicon device known as a computer chip. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. This generation marked the origin of mini computers in use today. Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. 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. 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. System Design which includes all of the other hardware components Furthermore, graphics images and audio and video files require large file capacities. 3. The interrupt signal is sent along a control line to the processor, and the currently executing program is suspended while control is passed to an interrupt service routine. Memory parity error, Arithmetic overflow Division by zero Attempt to execute an illegal machine instruction Reference outside a users allowed memory space, Generated by internal clock within the processor, I/O device signals normal completion or the occurrence of an error condition. college. iv.
