The transistor is touch pads and joystick are examples of input devices. 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. They can be linked to smaller 2kb and speed of processing was also very low. In Fig 1.3 you can see the ejector clips (D), using your finger, push these into the down position as shown in Fig 1.3, this allows the memory to be inserted. Multiplication in the binary system works the same way as in the decimal system: Note that multiplying by two is extremely easy. Temporary Result: 1; Carry: 0, Column 2^1: 1+1=10. WebLecture notes of Prof David Brooks could also be referred. 2022, Assignment 1. First generation computers (1946-1956) The largest power of 2 in 11 is 8, or 2^3. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. This is inflexible and so regular ROMs are only used generally for 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. A mainframe is another giant computer after the super computer and can also process millions of instruction per second and capable of accessing billions of data .They are physically very large in size with very high capacity of main memory. vdu controller.

Kurose,W. When the CPU wishes to access a particular memory location, it sends this address to memory on the address bus. 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). 17. Explain the different storage units of a computer such as byte, Kilobyte, Hardware units (Devices) of a computer can be categorized into five units; 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. This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. The next change came after about 1600 years. The processor communicates and controls a peripheral device through an I/O or device controller. The EISA bus is found on Intel 80386, 80486 and early Pentium computers. drive. 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. Explain the evolution of computing technology and the technological Two read/write heads are on each arm, one facing up for the surface above it and one facing down for the surface below it. It Converts an Computer systems are constructed of digital electronics. does not cover memory design in any depth and I will provide detailed The take-up reel always stays with the magnetic tape unit. Programmable ROM (PROM): This is a type of ROM that can be programmed The IBM 360 is an example of third generation computers. These computers used transistors after invention of transistors. WebCS385 Computer Architecture, Lecture 1 Reading: Patterson & Hennessy - Chapter 1 Topics: Introduction, Computer Architecture = Instruction Set Architecture + Machine B. Electrically Alterable Read-Only Memory(EAROMs) can be modified a bit at a They are used for complex tasks requiring a lot of computational power. 2. A mainframe is another giant computer after the super computer and can also 3. 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. 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. In such a system a task is broken down and shared among processes Furthermore, data files, particularly those accessed by several users, are subject to errors introduced by users. device. 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.

WebComputer architecture, like other architecture, is the art of determining the needs of the user of a structure and then designing to meet those needs as effectively as possible within economic and technological constraints. F.P. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. Two reels are used, a supply reel and a take-up reel. A graphical user interface (GUI) allows the user to interact with the system using Windows, Icons, Menus, and Pointers to control the operating system. modes, processor registers, and address and data formats. As you know, the decimal system uses the digits 0-9 to represent numbers. First machine in this category was ENIAC (electronic discrete variable automatic computer) and later came UNIVAC (universal automatic computers). (7mks). size though today the term is used to refer to large computers. Optimization, Memory An operating system acts as foundation on which other application software can be installed. It can process trillions of instructions in And, the access time is independent of the storage location. The data is recorded on the tracks that can be accessed by one positioning of the access arms-that is, on one cylinder. The transistor is smaller cheaper and produced less heat than vacuum tubes and consumed less power. 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. Assembly language is translated into machine code using an assembler before they can be executed. This is Storage technologies at all levels of the storage hierarchy can be differentiated by evaluating certain core characteristics as well as measuring characteristics specific to a particular implementation. They are mainly used for presentations. Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. Generations of computers They made use of vacuum tubes to store and process information. Information is stored in computers in the form of bits. Most disk packs, however, combine the disks, access arms, and read/write heads in a sealed module called a Winchester disk. A CD-R is a one time recordable compact disc. 2 0 obj scan. D.

The movies are made in two formats, each with their own coding. Video Failure Troubleshooting These two "bridges" connect the CPU to other parts of the computer. ()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. Obviously this is much more useful than a regular PROM, but it does require the erasing light. Since we divided the number by two, we "took out" one power of two. The process is the same for multiple-bit binary numbers: Column 2^0: 0+1=1. (2017). They are more susceptible to physical damage and viruses than the hard The hard disks are being improved as rapidly as DVD, and they definitely offer the fastest seek time and transmission rate (currently 5-10 MB/second).

The registers shown in the block diagram above, which represents a typical computer, each have a specific purpose, which is described below. They were huge in size and occupy a room. The term mainframe was mainly used for earliest computers as they were big in size though today the term is used to refer to large computers. software for instance, is an organizational issue that generally has nothing to do Commands tell the computer to do something, like save the file. A data bus provides a bi-directional path for moving data and instructions between system components. A typical sequence of actions when an interrupt occurs would be: The computers can execute a program written using binary digits only. Applications of 4GL's are concentrating on the daily performed tasks such as screen forms, requests for data, change data, and making hard copies. When you hear reference to a "flash BIOS" or doing a BIOS upgrade by "flashing", this refers to reprogramming the BIOS EEPROM with a special software program. This requires a transmission rate of 4692 bits per second. Computers have circuits that can add, subtract, multiply, divide, and do many other things to numbers stored in binary. the manufacturer. The purpose of the control bus is to transmit command , timing and specific status information between system components such as the memory, processor, keyboard input controller VDU output controller and the Disk I/O controller. 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. Also it will be very difficult for a person to understand a machine language program written by another person. Fuller F., Larson B., Computers: Understanding Technology (Second Edition), Assessment: Examination -70%: Coursework -30%. 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 supply reel, which has the tape with data on it or on which data will be recorded, is the reel that is changed. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be Removable disk storage units were. Secondary storage, sometimes called auxiliary storage, is storage separate from the computer itself, where you can store software and data on a semi permanent basis. software program. this unit. The system unit is the unit that houses the processing unit (processor), memory, the input output controllers and the buses. In most of the Hollywoods movies it is used for animation purposes. WebComputer hardware components can generally be broken down into three categories: Processing Processing components are responsible for actually carrying out actions in They are used to enter Input Devices Disk data is quite reliable, especially within a sealed module. Over 100's of millions have been sold, making it the de facto standard. The programs written in assembly language are also machine dependent. 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. Reduce the bandwidth required of the large memory Processor Memory Can hold up to 700MB of information. the lecture -- the notes posted here provide, in some cases, more II. At the beginning of each fetch-execute cycle, the interrupt register is checked. Cache memory is a type of very fast memory that is used to improve the speed of a Organization: Cache, Main Memory, infrequent operation - most of the time the memory is used as a ROM. 18-213 18-240. To accommodate the increased speed, chip manufacturers have designed and built faster RAM chips. Put 1 in the 2^1 column, 0 in 2^2, and subtract 2 from 3. 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. Data access time was measured in micro-seconds. can do some action Mouse is a common pointing device (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. RDRAM (Rambus DRAM) involves a new memory design that achieves a higher data transfer speeds but it is expensive to manufacture. The Basic Input/Output System (BIOS) chip controls the most basic functions of the computer and performs a self-test every time you turn it on. memory. Applications software packages sometimes include a dozen diskettes or more; all these could fit on one optical disk with plenty of room to spare. Most 4GLs are used to access databases.

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. Computer System Architecture Notes: Computer To overcome the performance limitations of SDRAM, two competing technologies have been developed. information and issue commands to the computer. Such a disk cannot, obviously, be used for your files, but manufacturers can use it to supply software. Data access Record the 1. 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. stream peripherals can be attached to them. Dynamic RAM needs to be refreshed thousands of times per second. Each byte can be used to represent a number, letter or special character. 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. temperature, speed etc. It is the smallest of the three computers. The chipset is part of the motherboard's logic system and is usually made of two parts --the northbridge and the southbridge.

(0's and l's). Picture Window theme. Digital Computers: Digital computers are mainly general purpose computers that Introduced the use of very small electronic circuit called integrated circuits (IC) by combining several transistors together between 3 transistors to make 1 IC. The form factor is just one of the many standards that apply to motherboards. EISA is the second most commonly used interface for disk drives. Dividing 80 by 2 gives 40. I. Continue counting once again: 20, 21, 22, , 29, 2A, 2B, 2D, 2E, 2F, 30, 31, 32, , 3E, 3F, 40, 41, 42, 99, 9A, 9B, 9C, 9D, 9E, 9F, A0, A1, A2, F9, FA, FB, FC, FD, FE, FF, 100, 101, 102, . Watch the pattern of numbers and try to relate this to the way you count in decimal or binary. (b) List four of the conditions an ALU tests for. Interrupts are therefore assigned priorities so that when two interrupts are received simultaneously, the one with the highest priority is dealt with first. Programmable ROM (PROM): This is a type of ROM that can be programmed using special equipment (a PROM programmer. Commands tell the computer Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. It may also be defined as the science and art of selecting and interconnecting power. This can also be written as [(1*2^2)+(1*2^0)]. written and quite useful -- they were written by the instructor for unit, memory (ROM, RAM). The cost of computers decreased and the speed increased. The number 81 in binary would also have a 1 in the 2^0 column. 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. The disk in its drive is shown in Figure 3. This holding place is known as memory also called main storage and is internal to the computer consisting of RAM and possibly ROM. dj z(l6uHyB"C]Iie7tHDXWq@vd4KfqS)YZT&;"v%LqNm!ZTJ UWBD@^-1QA+'6b"V0s>x$*Y l(7`yAP.

Several disks can be assembled into a disk pack. For the sake of simplicity, throw away the remainder. Two's column: Dividing 162 by 2 gives 81. Web: mku.ac. Alternatives such as Zip disks (discussed later), or transferring data via networks are making the low-capacity diskette become obsolete. In decimal form, 1+1=2. Perhaps more important than capacity, however, is the convenience of speed. 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. A large number of peripherals can be attached to them. III. D=0, so we are done, and the decimal number 163 is equivalent to the binary number 10100011. Used to put printed pictures and text into a computer. Word size means the number of Bits that the processor can process simultaneously. Icons represent programs, groups of programs, folders, devices and files. came UNIVAC (universal automatic computers). 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. They can be used as servers in companies. Temporary Result: 11 New D=40 D does not equal 0, so we repeat step 2. Let's try the number D=55. When the human race started doing some trade, it felt a need for a calculating keyboard controller or as output controller, e.g. It is a Then we just put this into columns. WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). 1 Software and Hardware The organization in this case is vertical. Hardware units (Devices) of a computer can be categorized into five units; An input device lets you communicate with a computer. 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. Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). Almost all the computers used nowadays are digital computers and we will There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. 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 byte can hold 28 different combinations of 0s and 1s, which means that for example, 256 different characters can be represented. the required results faster than human beings. These computers had programming languages whose vocabularies are close to the human natural language, English language. 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." Mainframe computers Only an interrupt with a higher priority is allowed to interrupt the servicing of another. Brooks, Planning a Computer System, Project Stretch, 1962 What does this design consist of? 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. Governments specially use this type of computer for their different calculations and heavy jobs. (2mks) (b). 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. with the ISA.
