Explain the evolution of computing technology and the technological 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. The micro chip technology has enabled reduction of size of. To read the data, the laser scans the disk, and a lens picks up different light reflections from the various spots. 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. Some systems feature dual BIOS, which provides a backup in case one fails or in case of error during updating. The processor and main memory of a PC are commonly held on a single board 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). the 0s and 1s with 0 representing an OFF state and 1 representing an ON state. The processor contains the control unit and the arithmetic/logic unit(ALU) and the system clock. 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. ()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. Explain how information is stored in a computer To provide an in-depth presentation of computer hardware and software with Writing takes place in a single pass of the focused laser beam. 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. Large computers have dozens or ever hundreds of disk drives. The fact that a disk is circular presents a problem: The distances around the tracks on the outside of the disk are greater than that of the tracks or the inside. 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. huge in size and occupy a room. Let's look at how this can help us convert from decimal to binary. A binary digit (1 or 0) is known as a BInary digiT which in short is a bit. Sometimes you can spot a blown capacitor on a motherboard, but it's not a common problem. Topics may include: instruction set design; processor micro-architecture and Course Info Instructors They are smaller than the main frame but bigger than microcomputers. Two reels are used, a supply reel and a take-up reel. Pages 4-. 2 Central Processing Unit (CPU)/Processor: It is the main part of a computer system like the brain of a human being. Four's column: Now we can subtract 1 from 81 to see what remainder we still must place (80). o Digital Camera Used to take electronic pictures of an object. video into a computer. Assembly language is translated into machine code using an assembler before they can be executed. 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. Software They coordinate computer activities and optimize use of computers. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. They are more susceptible to physical damage and viruses than the hard 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. DVD disks are read by a laser beam of shorter wave-length than used by the CD ROM drives. read the textbook and, preferably, the posted notes before coming to The system clock generates a continuous sequence of clock pulses to step the control unit through its operation. Binary is an effective number system for computers because it is easy to implement with digital electronics. So the number "193" is 1-hundreds plus 9-tens plus 3-ones.

(a). Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. A motherboard allows all the parts of your computer to receive power and communicate with one another. They used magnetic tape. designing their products. Input unit 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. III. Consequently, the primary role of tape today is as an inexpensive backup medium. Each byte can be used to represent a number, letter or special character. 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. Magnetic disks and drums are examples of direct-access storage media. level languages and provision of system software with the computer. Record the 11. They can be divided into; Are programs for user to do their jobs e.g. 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.

Their input /output capabilities were usually limited to A motherboard by itself is useless, but a computer has to have one to operate. for faster execution. processing. Web6.823 is a course in the department's "Computer Systems and Architecture" concentration. First generation computers (1946-1956) They are of advanced technology i.e. Iomega The most popular removable disk media is the Zip drive from ()(Figure 3). Here, a given item of data can be selected from anywhere in storage without having to scan any preceding items. To execute an assembly language program it should first be translates into an equivalent machine language program. compared to real read-write memory (RAM) where rewriting is done often many c l oc k , registers The x[r+&YU@lJSvB%d#QTD[/\{g\\S IV. An operating system acts as foundation on which other application software can be installed. 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. The largest power of 2 in 11 is 8, or 2^3. 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). But this is not practical for a system with many files or many users. The control unit coordinates and controls all the operations carried out by the (d) Convert the following into binary showing your working: i) 45 ii) 97, (f) What is a computer bus? Try converting these numbers from binary to decimal: | | | 1 | 0 | | 1 | 1 | 1 1 | 0 | 1 | 0 | 1 1 | 1 | 1 | 1 | 0. This indicates the speed at which the CD can transfer data to the CPU -the higher the X factor, the faster the CD. Word size also determines the speed of the computer. I. Most 4GLs are used to access databases. The movies are made in two formats, each with their own coding. links that I will post to other websites. Motherboards have come a long way in the last twenty years. I. They made use of vacuum tubes to store and process information. Let's take a look at how it works.

D&T: Programming and problem A CD-RW allows you to read, write, erase and write again. We can easily see that the number 3= 2+1. The fetch execute cycle Follow the same rules as in decimal division. programs that are static (not changing often) and mass-produced. A network operating system is required when a number of computers are connected together to form a network. Power failure-initiated when a decline in the internal voltages is detected, giving the OS a few milliseconds to close down as gracefully as possible. 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." You should also Once full, a removable hard disk cartridge can be replaced with a fresh one. Direct-access storage allows you to access the 125th record without first having to read the 124 records in front of it. WebComputer architecture is the science and art of selecting and interconnecting hardware components to create a computer that meets functional, performance and cost goals. Performance and Code The decimal number "2" is written in binary notation as "10" (1*2^1)+(0*2^0). Optimization, Memory In most of these cases one deals with Data Base Management Systems (DBMS). Explain the different types of computers categorized based on size, price implementations for the various parts of a computer, focusing largely on Let's try the number D=55. At the beginning of each fetch-execute cycle, the interrupt register is checked. computational power. Hard disks come in a variety of sizes. This categories are based on size, price and capabilities. Since these programs use only '0's and '1's it will be very difficult for developing programs for complex problem solving. Cas a model of computation Digital logic as a model of computation Programmers view of how a computer system works HW designers view of Define computer data storage. may be entered into a computer system. They are slower and less costly compared to mainframe computers but more powerful, reliable and expensive than micro computers. Since 3>1, we need to use an extra column to the left, and indicate it as "11" in binary (1*2^1) + (1*2^0). Rewriting an EAROM is intended to be an infrequent operation -most of the time the memory is used as a ROM. taken by a digital camera can be used directly by a computer ci Ny&V3Otu1gz=}

Table of Contents. 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. The two components (hardware, software) will be discussed later in other chapters. The data in that memory location is then returned to the CPU on via the data bus. The shape and layout of a motherboard is called the form factor. Typically, a CD ROM holds up to 650 MB of information. 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. next change came after about 1600 years. The first column we fill is the rightmost column, which is 2^0, or 1. Then, replace each block of four digits with its corresponding hexadecimal digit. The system unit is the unit that houses the processing unit (processor), memory, the input output controllers and the 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. This change further decreased the size, heat output and the maintenance complexity of the computers while increasing its speed. The form factor affects where individual components go and the shape of the computer's case. A computer has to main components; Computer System Architecture Notes: Computer Many new PCs come with Zip drives built in addition to floppy drives. 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). called a mother board. Explain the characteristics of computers and how they are different from An input device lets you communicate with a computer. A set of programs associated with the operation of a computer. The arithmetic/logic unit(ALU) plays two roles. 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. When a read/write head does accidentally touch the disk surface, this is called a head crash and all data is destroyed. When operating in a sequential environment, a particular record can be read only by first reading all the records that come before it in the file. This allows for smaller indentations and increased storage capacity. So can be able to read and write into the main memory (RAM). to do something, like save the file.
