Box 342-01000 Thika info@mku.ac.ke Email: www.mku.ac.ke Web: Instructional Manual for BBIT Distance Learning. 2022, Assignment 1. Since each sector on the disk holds the same amount of data, more sectors mean more data storage than if all tracks had the same number of sectors. The organization in this case is vertical. ()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. the micro era based on large scale integration that confines several physical components per small elements thumb size IC, hence the size reduced. infrequent operation - most of the time the memory is used as a ROM. Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. Hybrid Computers: Hybrid computers incorporate the technology of both analog and III. The p ro c essor ; Ari th m eti c an d Logi c Unit , C ontro l U n it , sy st em Diskettes became popular along with the personal computer. The processor communicates and controls a peripheral device through an I/O or device controller. requiring expensive equipment. There are different types of disk packs, with the number of platters varying by model. The speed of these machines was described in nanoseconds (1/1,000,000,000 of a second). But estimating future needs is rarely easy. Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. The code written by the programmer is called the source code and the compiled code is called the object code. Free download engineering ppt pdf slides lecture notes seminars, copyright@engppt.com. 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. They are Examples of this are Ms. Dos, and Windows. It has special keys for They were huge in size and occupy a room. The amount of data on a tape is expressed in terms of density, which is the number of characters per inch (cpi) or bytes per inch (bpi) that can be stored on the tape. The lecture Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. a lithium battery. In most of the Hollywoods movies it is used for animation purposes. The size of a computer's cache may be entered into a computer system. 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. In fact, programming a PROM is also called burning, just like burning a CD-R, and it is comparable in terms of its flexibility. Computer architecture or digital computer organization is the conceptual design and fundamental operational structure of a computer system. 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. the capacity to hold significantly more data than a 5-1/4 inch diskette. The outer gold layer is semi transparent, to allow reading of the underlying silver layer. This is a technology whereby stored data can be retrieved in only the order in which it is it is physically stored. 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. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. does not cover memory design in any depth and I will provide detailed These two "bridges" connect the CPU to other parts of the computer. The first place to start is always confirming that the power supply is operating properly. ROM package, through which you can actually see the chip that holds the Furthermore, data security is improved because if a disk fails, the disk system can reconstruct data on an extra disk; thus, computer operations can continue uninterrupted. 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. 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. Thus, we would put a 1 in the 2^6 column, and subtract 64 from 75, giving us 11. Color laser printers are still fairly expensive. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. In most of the Hollywoods movies it is used for animation purposes. {HnzIxfjw^K](^$L 2kb and speed of processing was also very low. Let's try the number D=55. Cache memory is a type of very fast memory that is used to improve the speed of a computer doubling it in some cases. class. Iomega The most popular removable disk media is the Zip drive from ()by which the central processing unit (CPU) performs internally and accesses ()addresses in memory. Therefore, it would shift you one column to the left. A computer has to main components; The form factor affects where individual components go and the shape of the computer's case. i. Not all computer hardware uses voltage, however. 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. Removable disk storage units were. P.O. 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. Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. B. Power supplies often fail gradually, giving rise to symptoms that appear to be caused by individual component failure. read the textbook and, preferably, the posted notes before coming to Minicomputers Since we already knew how to convert from binary to decimal, we can easily verify our result. The term mainframe was mainly used for earliest computers as they were big in A keyboard, mouse, scanner, digital camera, touch pads and joystick are examples of input devices. Data can also be destroyed if a read/write head encounters even minuscule foreign matter on the disk surface. Temporary Result: 1; Carry: 0, Column 2^1: 1+1=10. For example, "3" in binary cannot be put into one column. Other controllers operate in one direction only, either as an input controller, e.g. Storage capacity was Motherboard failures usually show up as second level problems, like "I've replaced the video card and the screen is still dead." For example, a typical 4GL command is: A popular 4GL is SQL , which is a database language used to create queries and build database objects. Particularly step 3, "filling in the zeros." Input unit (c) Explain the use of registers in the CPU. Purpose of the course 500,000 physical elements e. transistors, capacities, diodes etc per Binary is an effective number system for computers because it is easy to implement with digital electronics. r4haJq%e$\, $miMxgy`3*VNae!/yfA){$q> ozEW|%H j],zwG"D=|y'TcZ$RT^%8JityYjwG6CRj{r!MEt4N]O#(Is6x6by

In short a COMPILER is: the translator of the source code into computer language. time, but writing is a slow process and uses non-standard voltages (usually Data access time was measured in micro-seconds. Looking at this in columns. came UNIVAC (universal automatic computers). To provide an in-depth presentation of computer hardware and software with chip(IC). Two's column: Dividing 162 by 2 gives 81. the keyboard and or punched card input and printer and or punched cart output. 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. 6.823 is a study of the evolution of computer architecture and the factors influencing the Execute cause the instruction to be executed. They support concurrent users. A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. They are smaller than the main frame but bigger than microcomputers. These computers were mostly They used magnetic tape. The following program written in BASIC language is to add two given numbers. Computer System Architecture Notes: Computer Prepare an oral presentation of approximately 25 min. According to the utilization of computer for different uses, computers are of following two types: According to the technology used, computers are of following three types: Computer hardware refers to the physical components of a computer such as the monitor, Keyboard, Mouse, system unit etc. devices. The small circuitry that resulted improved the processing speed i.e. A disk pack is mounted on a disk drive that is a separate unit connected to the computer. AxgyL@0#jE:3tBP20zivoKJ]2w\$wkNIkyDXQwsACvc; hq W j 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.

A disadvantage of a removable hard disk is that it takes longer to access data than a built-in hard drive. Subroutines, Solution to Vector Inner (Dot) Output Saving and retrieving information from a floppy disk is slower than on a hard drive. Practically, we can simply keep a "running total", which now stands at 11 (a[1]=1 and a[0]=1). The lecture notes posted are not A compiler is a program that translates high level language instructions into machine code. Storage capacity was very low i.e. Programming and problem Email: info@mku.ac reliable and expensive than micro computers. The tubes consumed a lot of power and generated a lot of heat (overheating). This opens the possibility to write data in two layers. individuals. Interrupts are therefore assigned priorities so that when two interrupts are received simultaneously, the one with the highest priority is dealt with first. memory. 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. Their input /output capabilities were usually limited to the keyboard and or punched card input and printer and or punched cart output. (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? It is usually necessary to scan some (but not all) of the preceding data. Here we are blurring the line a bit between what "read-only" must match the DVD region. 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. The two components (hardware, software) will be discussed later in other chapters. In 1998 Macintosh introduced its new computer, the IMAC, without a floppy disk drive. Central processing unit (CPU) or processor Although the user enter data in decimal or character form, it is converted into binary digits C. The motherboard; form factor, sockets and slots Thus, the answer is 71. multiplication and division.. and to perform computations on these measurements. touch pads and joystick are examples of input devices. They can be linked to smaller computers and handle hundreds of users they are also used in space exploitation. It They are usually called personal computers since they are designed to be used by individuals. 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. very low i.

Chapter 2- Basic Organization of a Computer. Writing and understanding programs in assembly language is easier than that of machine language. The processor has the following functions: The control unit coordinates and controls all the operations carried out by the computer. However, this is not the only approach possible. and accesses addresses in memory. Can hold up to 700MB of information. 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 ? 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. Optimization, Memory They used magnetic tape. Organization: Cache, Main Memory, category was ENIAC (electronic discrete variable automatic computer) and later Using a method called helical scan recording, DAT wraps around a rotating read/write head that spins vertically as it moves. Over 100's of millions have been sold, making it the de facto standard. within a computing system such as: Objectives and cost goals. software program. For many applications, EAROM has been supplanted by CMOS RAM backed-up by a lithium battery. State three types of computer buses. The transistor is Hexadecimal is more compact than binary but is still based on the digital nature of computers. In assembly language mnemonic codes are used to develop program for problem solving. 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. level languages and provision of system software with the computer. WebLecture notes Chapters 1-3, 5-12 The CMU ICS+ coursethat covers everything in CS:APP3e except Chapter 4 (Processor Architecture). This is inflexible and so regular ROMs are only used generally for To understand binary numbers, begin by recalling elementary school math. The CPU of a 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. to the C language (part 2/2), Run-time Computer architecture or digital computer organization is the conceptual 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. Chapter 3- Instruction slower and less costly compared to mainframe computers but more powerful, 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) video recorder Data access Explain the evolution of computing technology and the technological This is significant data insurance. Central Processing Unit is refer to the C. Characteristics of computers It is the smallest of the three computers. ii. The largest power of 2 in 11 is 8, or 2^3. B. A large number of peripherals can be attached to them. Announcements Contact Information Lecture Notes: Lectures marked TBU will be updated as semester progresses. At the end of the chapter the learner shall be able to; software 10100011=(1*2^0)+(1*2^1)+(1*2^5)+(1*2^7)=1+2+32+128= 163. iii. WebLecture notes of Prof David Brooks could also be referred. The CPU is connected to the main memory by three separate buses. Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. << /Length 4 0 R /Filter /FlateDecode >> WebComputer Architecture PPT Instructor Prof. Laxmi N.
