...system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes a system call to an OS function or be interrupted by it. Operating systems can be found on many devices that contain a computer—from cellular phones and video game consoles to supercomputers and web servers. Examples of popular modern operating systems include Android, BSD, iOS, Linux, OS X, QNX, Microsoft Windows, Windows Phone, and IBM z/OS.. History 1. Windows - The first Windows system was released in 1985. Originally, it was just a graphical user interface on top of MS-DOS – a state of affairs that lasted until the release of Windows 95, when MS-DOS products were integrated into Windows. Windows 95 was a huge departure from the previous systems and was the first major step in Window’s transition from GUI to operating system. 2. Apple - The Apple Macintosh system is a little older than Windows, having first been released in 1984. From the start, it was an entirely graphical operating system, and from quite an early stage became popular among the earliest computer graphic designers. In 2005, Apple changed the design and structure of Mac OS, moving from...

...Week 4 Lab 1 This lab involves research on the size, speed, and slot type for RAM, as well as the model, interface type, capacity, and transfer rate of hard disks and optical disks in your computer system. Required Setup and Tools In this laboratory, you need: * A desktop or notebook computer * Access to the Internet for research Recommended Procedures Task 1: Examining RAM To find out the types of RAM available to upgrade your computer, follow these steps: 1. Acquire computer information: Determine the make, model, and serial number of your computer by physically examining it. On a desktop computer, these numbers are on the back of the computer. For a laptop computer, this information is on the bottom of the computer. If the model and serial number are not clearly visible, refer to the manufacturer’s website for this information; otherwise, select a laptop you would consider buying for yourself and use its model number to obtain the information. a. Service Tag FPR5SW1 b. Computer Model Inspiron N7010 1 In Microsoft 10 go to life at a glance. 2 Go to settings 3 System 4 about That is where you will find it very simple. 1.

...An operating system is the software that manages the hardware and software resources, it is required for most application programs to function. Operating systems work as an in-between for the programs and computer hardware. It is responsible for allocating computer resources for efficient use of space and power. There are three major operating systems in use today and they are Windows, Linux, and Mac OSX, and each has its own pros and cons depending on what you are using it for. Mac OSX is the operating system used by Apple for their computers. Mac OSX will only work on Macintosh computers with PowerPC or Intel processors, as opposed to Windows and Linux which are compatible with most brands. Mac OSX uses a graphical user interface that is popular with musicians and artist because it has more readily available design/media software. Several high-end graphic, video and audio applications were developed for Mac platforms in the early days of personal computers and the trend has continued even though the applications have been ported for Windows they still run more efficiently on Macs making them preferable for people in the creative arts community. Many people also like OSX for its ease of use and their frequent updates via point releases that make the computer run more efficiently. Linux is a growing number of operating systems meant to run in computers, phones, and several more electronic devises. Linux was created by Linus Torvalds as a free alternative to Windows. The graphical...

Explain major differences between binary and BCD numeric representations. Ans 2: BCD each digit of a decimal number is coded as a 4 bit binary number between 0 and 9. This is not used too often as it is difficult to do calculations in BCD as opposed to binary, and it is not efficient – uses more bits than a binary coded number would. In Binary the number is converted to base 2, binary code. Planning: 1. Provide a list of places that you can obtain the datasheets for the following components: ...

...Lab 4.1 – Pseudocode and Modules (“UTP Installed”) Critical ReviewA Module is a group of statements that exists within a program for the purpose of performing a specific task.Modules are commonly called procedures, subroutines, subprogram, methods, and functions.The code for a module is known as a module definition. To execute the module, you write a statement that calls it.The format for a module definition is as follows:Module name()StatementStatementEtc.End ModuleCalling a module is normally done from the Main() module such as:Call name()Generally, local variables should be used and arguments should be passed by reference when the value of the variable is changed in the module and needs to be retained. For example:Module main()Real Integer numberCall inputData(number)Call printData(number)End Module// Accepts number as a reference so that changed value// will be retainedModule inputData(Real Ref number)number = 20End Module// number does not need to be sent as reference because// number is not going to be modifiedModule printData(Real number)Display “The number is “, numberEnd Module | This lab requires you to think about the steps that take place in a program by writing pseudocode. Read the following program prior to completing the lab. Data Communications Corp wants a small program that will calculate the cost of UTP it installs for their clients.

...Lab 7: Functions This lab accompanies Chapter 6 of Starting Out with Programming Logic & Design. Name: ___________________________ Lab 7.1 – Functions and Pseudocode Critical Review You have been coding with modules in pseudocode and functions when using Python. You modules in pseudocode can be made into functions by returning a value. A function is a special type of module that returns a value back to the part of the program that called it. Most programming languages provide a library of prewritten functions that perform commonly needed tasks. Library functions are built into the programming language and you can call them as needed. They are commonly performed tasks. Help Video: View the tutorial video titled, "lab7-1.wmv" to assist you in completing this lab assignment. Writing Your Own Function that Returns an Integer Step 1: A function contains three parts: a header, a body, and a return statement. The first is a function header which specifies the data type of the value that is to be returned, the name of the function, and any parameter variables used by the function to accept arguments. The body is comprised of one or more statements that are executed when the function is called. In the following space, complete the following: (Reference: Writing Your Own Functions, page 225). a. Write a function with the header named addTen. b. The function will accept an Integer variable named number. c. The function body will...
