Assembly language is designed mainly to replace each machine code with and understandable mnemonic code. They are smaller than the main frame but bigger than microcomputers. 1 Software and Hardware Hybrid Computers: Hybrid computers incorporate the technology of both analog and Punched cards, paper tape, and magnetic tape are examples of sequential-access storage media. Data access computer can process Because of their digital nature, a computer's electronics can easily manipulate numbers stored in binary by treating 1 as "on" and 0 as "off." Explain the fundamental difference between computer hardware and 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. The take-up reel always stays with the magnetic tape unit. This process continues until we have a remainder of 0. It is designed to perform a specific function and cannot be changed. touch pads and joystick are examples of input devices. Follow the same rules as in decimal division. They are expensive to install. A key advantage of a tape backup system is that it can copy the entire hard disk in minutes, saving you the trouble of swapping diskettes in and out of the machine. 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. This fact makes it easy to convert between binary and hexadecimal. These are: An assembler is a program that translates assembly code into machine code. 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. Region one is USA and Canada, while Europe and Asia is region two. D&T: Flash memory is used for easy and fast information storage in computers, digital cameras and home video game consoles. Add 1 from carry: 10+1=11. Almost all the computers used nowadays are digital computers and we will written and quite useful -- they were written by the instructor for video recorder This presentation is available free for non-commercial use with attribution under a creative Microsoft, Borland, IBM, and other companies make 5GL visual programming products for developing applications in Java, for example. drive. 500,000 physical elements e. transistors, capacities, diodes etc per Both types of RAM are volatile, meaning that they lose their contents when the power is turned off. These two "bridges" connect the CPU to other parts of the computer. A disadvantage of a removable hard disk is that it takes longer to access data than a built-in hard drive. Explain the different types of computers categorized based on size, price The process is the same for multiple-bit binary numbers: Column 2^0: 0+1=1. 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. 6.823 is a study of the evolution of computer architecture and the factors influencing the design of hardware and software elements of computer systems. computational machines. Many users, therefore, make later adjustments like adding a removable hard disk cartridge to accommodate expanding storage needs. The stored bits are usually retrieved from computers memory for manipulation by the processor. Graphical user interface has some disadvantages such as. Magnetic disks and drums are examples of direct-access storage media. In binary, any digit higher than 1 puts us a column to the left (as would 10 in decimal notation). The processor and main memory of a PC are commonly held on a single board called a mother board. Different industries also use this huge computer for designing their products. Particularly step 3, "filling in the zeros." III. computers and handle hundreds of users they are also used in space exploitation. Flash memory is a type of EEPROM chip, which stands for Electronically Erasable Programmable Read Only Memory. 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. category was ENIAC (electronic discrete variable automatic computer) and later This document should be seasone Computer Architecture and Assembly Language Programming, Computer Organization and Design 4th Edition Solution, Comporg 6 sol2 - Solution manual for the second Chapter of the Computer Architecture, CS401 Quiz 1 Solution by MCS of Virtuallians. (b) List four of the conditions an ALU tests for. image into dots that the computer can understand .To scan text, optical peripherals can be attached to them. P.O. WebComputer hardware components can generally be broken down into three categories: Processing Processing components are responsible for actually carrying out actions in many applications, EAROM has been supplanted by CMOS RAM backed-up by window for a specified period of time, which will erase the EPROM and allow it For Saving and retrieving information from a floppy disk is slower than on a hard 18-213 18-240. o Pointing Devices Pointing devices move some object on the screen and information and issue commands to the computer. processing. The first calculating device, which was used 2000 years ago was called Everything that runs the computer or enhances its performance is either part of the motherboard or plugs into it via a slot or port. a similar course at Univ. 2. Picture Window theme. The two components (hardware, software) will be discussed later in other In our vertical notation. A keyboard, mouse, scanner, digital camera, The following are the different types of interrupt that could occur; There is a special register in the CPU called the interrupt register. 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). Next, add {(2+4) +1} (the one is from the carry)=7, which is put in the 10's column of the sum. The truth is, of all the four subsystems represented in this table, hard drives are probably the most reliable. These computers had programming languages whose vocabularies are close to the human natural language, English language. Erasable Programmable ROM (EPROM): An EPROM is a ROM that can be erased and reprogrammed. They are slower and less costly compared to mainframe computers but more powerful, reliable and expensive than micro computers. Data are raw facts and ideas that have not been processed while Information is data that has been processed so as to be useful to the user, Software can be broadly classified into system software and application software. 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." changed.

A network operating system is required when a number of computers are connected together to form a network. software. by "flashing", this refers to reprogramming the BIOS EEPROM with a special This is inflexible and so regular ROMs are only used generally for programs that are static (not changing often) and mass-produced. the required results faster than human beings. 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. Special storage locations called registers are included in this circuitry to hold information temporarily while it is being decoded or manipulated. i.e., the programs were machine dependent. They can be used as servers in companies. the number 193 is really {(1*10^2)+(9*10^1)+(3*10^0)}. The width of the data bus is a key factor in determining overall system performance. Take the number 163. All the processor activities, such as fetching an instruction, reading data into the memory register etc. The arithmetic/logic unit(ALU) plays two roles. implemented in a single piece of silicon device known as a computer chip. Email: info@mku.ac As we have already noted, magnetic tape is used primarily for backup purposes. Removable disk storage units were developed for use on these machines.

(Powerpoint is for instructors who want to give lectures themselves based on CS 252.) Web1 cache.1 361 Computer Architecture Lecture 14: Cache Memory cache.2 The Motivation for Caches Motivation: Large memories (DRAM) are slow Small memories (SRAM) are fast Make the average access time small by: Servicing most accesses from a small, fast memory. Try converting these numbers from binary to decimal: | | | 1 | 0 | | 1 | 1 | 1 1 | 0 | 1 | 0 | 1 1 | 1 | 1 | 1 | 0. drive. A 4GL is an aid which the end user or programmer can use to build an application without using a third generation programming language. Floppy Disk: Floppy disks allow information to be transported easily from one computer to another they have limited storage capacity, generally 1.44 MB. (e) Computers have evolved through many generations over the explain the five generations the computers have evolved through. A motherboard allows all the parts of your computer to receive power and communicate with one another. seconds. In addition, the EISA can accommodate a 16-bit ISA card in the first row. WebLecture 1 : Evolution of Computer Systems: Download Verified; 2: Lecture 2 : Basic Operation of a Computer: Download Verified; 3: Lecture 3 : Memory Addressing and write, because when they change their code they can create new PROMs without 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! data .They are physically very large in size with very high capacity of main What happens when, for example, a key on the keyboard is pressed, thus generating an interrupt? 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. Removable disk storage units were. Computers have circuits that can add, subtract, multiply, divide, and do many other things to numbers stored in binary. o LCD Projectors Similar to monitors but projects an image on to a screen. In assembly language mnemonic codes are used to develop program for problem solving. 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. You cannot read just any record at random. Only an interrupt with a higher priority is allowed to interrupt the servicing of another. Subroutines, Solution to Vector Inner (Dot) 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. iii. These computers are used in networking .examples of micro computers are IBM PCs BBC micro etc. companies, and many other huge companies prefer mainframe because of its 2kb and speed of processing was also very low. Operators, Von Prepare an oral presentation of approximately 25 min. It is also easy to see that multiplying and dividing by 2 shifts everything by one column: two in binary is 10, or (1*2^1).

Computer System Architecture Notes: Computer The form factor affects where individual components go and the shape of the computer's case. higher voltages around 12 volts). WebLecture #4-5: Computer Hardware (Overview and CPUs) CS106E Spring 2018, Young In these lectures, we begin our three-lecture exploration of Computer Hardware. 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. We can start at the right, rather than the left. Other controllers operate in one direction only, either as an input controller, e.g. vdu controller. It interprets the instructions in the program and executes one by one. to be reprogrammed again. The movies are made in two formats, each with their own coding. The set of instructions is often called a program or, if the set is particularly large and complex, a system. DDR SDRAM (Double Data Rate SDRAM) can transfer data twice as fast as SDRAM because it reads data twice during each clock cycle. generation saw the introduction of more complex ALU and CPU, the use of high must match the DVD region. Software: Categories of software, System software, applications software, 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. 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. Execute cause the instruction to be executed. There are several specific form factors that most PC motherboards use so that they can all fit in standard cases. ROM: A mask programmed read only memory that can be only be produced by Since 00110101 has eight digits, it can be divided into two blocks of four digits, 0011 and 0101. In some cases, in addition to the lecture notes (from Final result: 11001. The design of these computers was based on VLSI (very large scale integration) technology, the micro chip technology that gave rise to the smaller computers known as the micro computers in use today. chip(IC). Data on the track is accessed by referring to the surface number, track number, and sector number where the data is stored. The highest-capacity tape is the digital audio tape, or DAT, which uses a different method of recording data. The tubes power.

Includes the semester schedule and a complete set of PowerPoint lecture notes and associated code, updated for CS:APP3e. 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. Magnetic tape looks like the tape used in music cassettes plastic tape with a magnetic coating. A motherboard by itself is useless, but a computer has to have one to operate. To converty from binary to hexadecimal, reverse the procedure and break the binary number into blocks of four digits. Ultraviolet light of a specific frequency can be shined through this Many cartridges and cassettes have the supply and take-up reels built into the same case. 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). Need sound recording A graphical user interface (GUI) allows the user to interact with the system using Windows, Icons, Menus, and Pointers to control the operating system. Hexadecimal is more compact than binary but is still based on the digital nature of computers. It controls and monitors the running of application programs. Compact Disk Read Only Memory (CD ROM): CD ROMs are read only storage medium. This is mostly hard drives and removable media such as floppy disks, optical media (CD ROM) etc. This is inflexible and so regular ROMs are only used generally for 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. Now I can imagine even the extra disk filling up.". 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. size IC, hence the size reduced.
