i/c(Power-on self-test)

Power-on self-test




Power-on self-test (POST) is the common term for a computer, router or printer's pre-boot sequence. The same basic sequence is present on all computer architectures. It is the first step of the more general process called initial program load (IPL), booting, or bootstrapping. The term POST has become popular in association with and as a result of the proliferation of the PC. It can be used as a noun when referring to the code that controls the pre-boot phase or when referring to the phase itself. It can also be used as a verb when referring to the code or the system as it progresses through the pre-boot phase. Alternatively, this may be called "POSTing."

For embedded systems power-on self-test (POST) refers to the testing sequence that occurs when a system is first powered on. POST is software written to initialize and configure a processor and then execute a defined series of tests to determine if the computer hardware is working properly. Any errors found during the self-test are stored or reported through auditory or visual means, for example through a series of beeps, flashing LEDs or text displayed on a display. Once the POST sequence completes, execution is handed over to the normal boot sequence which typically runs a boot loader or operating system. POST for embedded systems has been around since the earliest

i/c

Instruction cycle
Each computer's CPU can have different cycles based on different instruction sets, but will be similar to the following cycle:

1. Fetch the instruction

The CPU presents, on the address bus, the value stored in the Program Counter. This is the memory address of the next instruction that is to be executed. The CPU then fetches the instruction from main memory via the data bus, and it is then placed into the CIR. The Program Counter is incremented to contain the address the next instruction.

2. Decode the instruction

The instruction decoder interprets the instruction. If the instruction has an indirect address, the effective address is read from main memory, and any required data is fetched from main memory to be processed and then placed into data registers.

3. Execute the instruction

The CU passes the decoded information as a sequence of control signals to the relevant function units of the CPU to perform the actions required by the instruction such as reading values from registers, passing them to the ALU to perform mathematical or logic functions on them, and writing the result back to a register. If the ALU is involved, it sends a condition signal back to the CU.

4. Store results

The result generated by the operation is stored in the main memory, or sent to an output device. Based on the condition of any feedback from the ALU, Program Counter may be updated to a different address from which the next instruction will be fetched.
The cycle is then repeated.

Fetch cycle

Steps 1 and 2 of the Instruction Cycle are called the Fetch Cycle. These steps are the same for each instruction. The fetch cycle processes the instruction from the instruction word which contains an opcode and an operand.

Execute cycle

Steps 3 and 4 of the Instruction Cycle are part of the Execute Cycle. These steps will change with each instruction.
The first step of the execute cycle is the Process-Memory. Data is transferred between the CPU and the I/O module. Next is the Data-Processing uses mathematical operations as well as logical operations in reference to data. Central alterations is the next step, is a sequence of operations, for example a jump operation. The last step is a combined operation from all the other steps.

Initiating the cycle

The cycle starts immediately when power is applied to the system using an initial PC value that is is predefined for the system architecture (in Intel IA-32 CPUs, for instance, the predefined PC value is 0xfffffff0). Typically this address points to instructions in a read-only memory (ROM) which begin the process of loading the operating system. (That loading process is called booting.)[1]

The Fetch-Execute cycle in Transfer Notation

MAR\gets PC
MDR\gets Memory[MAR]
PC\gets PC+1 (Increment the PC for next cycle)
CIR\gets MDR

The registers used above, besides the ones described earlier, are the Memory Address Register (MAR) and the Memory Data Register (MDR), which are used (at least conceptually) in the accessing of memory.

i/c(all bus) ......

All computers use three types of basic buses. The name of the bus is generally determined by the type of signal it is carrying or the method of operation. We group the buses into three areas as you see them in their most common uses. They are as follows:
Control (also called timing and control bus) bus,
Address bus, and
data (also called a memory bus) bus.
Instruction (I), Operand (O), Input/Output Memory (I/O MEM) or Input/Output Controller (IOC), and Computer Interconnection System (CIS) Time multiplexed bus
Control Bus
The control bus is used by the CPU to direct and monitor the actions of the other functional areas of the computer. It is used to transmit a variety of individual signals (read, write, interrupt, acknowledge, and so forth) necessary to control and coordinate the operations of the computer. The individual signals transmitted over the control bus and their functions are covered in the appropriate functional area description.
Address Bus
The address bus consists of all the signals necessary to define any of the possible memory address locations within the computer, or for modular memories any of the possible memory address locations within a module. An address is defined as a label, symbol, or other set of characters used to designate a location or register where information is stored. Before data or instructions can be written into or read from memory by the CPU or I/O sections, an address must be transmitted to memory over the address bus.
Data Bus
The bidirectional data bus, sometimes called the memory bus, handles the transfer of all data and instructions between functional areas of the computer. The bidirectional data bus can only transmit in one direction at a time. The data bus is used to transfer instructions from memory to the CPU for execution. It carries data (operands) to and from the CPU and memory as required by instruction translation. The data bus is also used to transfer data between memory and the I/O section during input/output operations. The information on the data bus is either written into.

o/s (i/c)

operating system (OS)

Definition

Master control program (such as DOS, Linux, MacOS, Solaris, Unix, and Windows) that automatically runs first when a computer is switched on, and remains in the background until the computer is turned off. It commonly comes preinstalled (on the boot section of the computer's main hard disk) and is usually the most complex and largest program to be used by the computer. A computer user is typically more affected by the capabilities and whims of the OS than by those of the hardware. Main services provided by an OS include (1) user-interface, (2) carrying out commands of the user and the application programs, (3) supervising installation and running of other programs and hardware, (4) controlling the input-output functions, (5) allocating system resources such as memory, processor time, disk space, and peripheral devices to regulate the flow of work within the computer, (6) handling file and directory management, and (7) providing file-sharing and networking functions.

A BIOS (Basic Input/Output System) is an electronic set of instructions that a computer uses to successfully start operating. The BIOS is located on a chip inside of the computer and is designed in a way that protects it from disk failure.
A main function of the BIOS is to give instructions for the power-on self test (POST). This self test ensures that the computer has all of the necessary parts and functionality needed to successfully start itself, such as use of memory, a keyboard and other parts. If errors are detected during the test, the BIOS instructs the computer to give a code that reveals the problem. Error codes are typically a series of beeps heard shortly after startup.

Q-1 Define icon?
ans:-


An icon is a small picture or symbol on a graphical user interface (GUI) that represents a program (or command), file, directory (also called a folder) or device (such as a hard disk or floppy). The term comes from the Greek word eikon, which means likeness, image or portrait.

A GUI is a user interface (i.e., a way of displaying things on a monitor screen) that uses windows, icons and menus and which can be manipulated by a mouse (or other pointing device, such as a trackball) in addition to (at least to some extent) the keyboard. This is in contrast to a command line interface (CLI), which uses text only and is accessed solely by a keyboard.

Icons were first developed in the 1970s at the Xerox Palo Alto Research Center (PARC) as a means of making computers easier for novices to use. Their first large-scale commercial application was on the Macintosh personal computer, which was introduced in 1984. Today virtually every major operating system employs icon-based GUIs.


Q-2 Explan rd and md command

ans:- Rd

The RD command removes a directory on the device, storage card, or the release directory on the remote desktop.

e.g.

c:\ rd xyz

Md

The MD command creates a directory on the device, storage card, or the release directory on the remote desktop.

e.g.

c:\ md xyz


Q-3 Defind my computer.

ans:- A computer is a programmable machine that receives input, stores and manipulates data//information, and provides output in a useful format.

While a computer can, in theory, be made out of almost anything (see misconceptions section), and mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). Originally, they were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computersfound in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.

Q-4 Explain property of taskbar

ans:- The easiest method of accessing the properties of the Taskbar is to right click on the Taskbar and select [Properties] from the context menu. The Taskbar and Start Menu Properties Property Sheet (Fig. UI-71) will open. The focus is on the Taskbar tab. The Property Sheet is divided into two sections that mirror the divisions of the actual Taskbar. The two areas are discussed below.


[Taskbar Appearance] - This area controls the center section of the Taskbar located between the Start Button on the left and the Notification Area on the right. The graphic at the top of this section will change to reflect the options selected or cleared.
[Lock the Taskbar] - The Taskbar can be positioned along the top, bottom, left, or right side of the desktop. Left click in any open area of the Taskbar and drag it to the desired location. Any changes you make to the Taskbar, including toolbars located on the Taskbar are locked and prevented from being moved with this selection.
[Auto-Hide the Taskbar] - Allows the Taskbar to retract to the edge of the screen when it’s not being used. To recall it to view, move the mouse to the edge of the screen where the Taskbar is positioned. Many users are hesitant to use this option but I suggest you give it a try. I personally expand the taskbar to two rows high in everyday use to accommodate more items with less side to side compression. The Auto-Hide feature reclaims this desktop space whenever the focus is on a program.
[Keep the Taskbar On Top of Other Windows] - Contrary to what this item description would indicate, when used in conjunction with the Auto-Hide the Taskbar option discussed previously, it simply ensures that when you move your mouse pointer to the edge of the screen the Taskbar will always become visible. It does not supercede the command to Auto-Hide the Taskbar by making it always visible.
[Group Similar Taskbar Buttons] - This is one of the best new features of XP for anyone who works with multiple open windows. The grouping occurs in two ways. First, it displays files opened by the same program in the same area of the Taskbar. For example, if you opened, in order, the following files: Excel 1, Word 1, Excel 2, and Word 2, normally the files would be displayed across the Taskbar in that same order. With grouping enabled, the order would be Excel 1, Excel 2, Word 1, and Word 2. In addition, if the size of the Taskbar windows falls below a certain width due to the Taskbar being crowded, grouping combines all the similar program files into expandable buttons containing the individual files. Having the files grouped by the parent program also allows you to close the entire group by right clicking the button and selecting [Close] rather than closing each file individually.
[Show Quick Launch] - Way back in 1988 Robert Palmer did a song titled “Simply Irresistible.” That pretty much sums up my feelings about Quick Launch. It resides over on the left side of the Taskbar (although you can drag and position it anywhere you want), is fully customizable and launches programs with a single click. Programs can be added to Quick launch by dragging and dropping. The minimum size for Quick Launch is the width of three icons. Icons over three (six in my case since I use a double height Taskbar) are accessible from a pop up listing by clicking on the [>>] symbol.
[Notification Area] - This area controls the far right section of the Taskbar adjacent to the edge of the screen where the clock is located if you have it activated. The graphic at the top of this section will change to reflect the options selected or cleared.
[Show the Clock] - Check the box, you have a clock. No check, no clock. Simple.
[Hide Inactive Icons] - The Notification Area has always been one of my pet peeves. Programs have a tendency to stick icons here on a regular basis. This is fine if they provide a simple way of turning them off, the most common method being via right click and context menu selection for disabling. Some icons in this area are truly useful. The bad part was the way they string across the taskbar with each new addition. The Hide Inactive Icons name only tells part of the story. While it is true that it will hide the inactive icons, it goes well beyond that function by selecting the [Customize...] button. The [Customize Notifications] (Fig. UI-72) dialogue box will open.



[Customize Notifications] - This dialogue box displays a list of Current Items and Past Items that have appeared in the Notification Area. Click on any item in either section and a drop down box will appear with three options.
[Hide When Inactive] - The default choice. Useful for items that you want to become visible when they have information to report.
[Always Hide] - A good choice for items you want to run in the background but don’t want a notification until you make the choice to expand the Notification Area.
[Always Show] - Useful for items which you want to monitor for both activity and inactivity so they are always available at a glance.

With the modifications that are possible to the Taskbar in Windows XP I’ve pretty much eliminated any need for the Start Menu on a regular basis. By carefully constructing the Taskbar, adding the programs that are most relevant to my work in the Quick Launch area and utilizing the Notification Area and Auto-Hide functions wisely, I’m able to increase available screen real estate and maintain access to essential programs and monitoring functions.

  5. Step5

    Click on Browse to use an image stored elsewhere on your hard drive. Locate the image and click Open.

  6. Step6

    Click OK to change your background, or wallpaper. Click Cancel if you decide to maintain your current settings.


    Q-6 short not desktop

    ans:- A desktop computer is a personal computer (PC) in a form intended for regular use at a single location, as opposed to a mobile laptop orportable computer. Prior to the widespread use of microprocessors, a computer that could fit on a desk was considered remarkably small. Desktop computers come in a variety of types ranging from large vertical tower cases to small form factor models that can be tucked behind anLCD monitor. "Desktop" can also indicate a horizontally-oriented computer case usually intended to have the display screen placed on top to save space on the desktop. Most modern desktop computers have separate screens and keyboards. Tower cases are desktop cases in the earlier sense, though not in the latter. Cases intended for home theater PC systems are usually considered to be desktop cases in both senses, regardless of orientation and placement.


    History



    Early computers took the space of a room. Minicomputers generally fit into one or a few refrigerator sized racks. It was not until the 1970s when computers such as the HP 9800 series desktop computers were fully programmable computers that fit entirely on top of a desk. The first large calculators were introduced in 1971, leading to a model programmable in BASIC in 1972. They used a smaller version of a minicomputer design based on ROM memory and had small one-line LED alphanumeric displays. They could draw computer graphics with a plotter. The Wang 2200 of 1973 had a full-size CRT and cassette tape storage. The IBM 5100 in 1975 had a small CRT display and could be programmed in BASIC and APL. These were generally expensive specialized computers sold for business or scientific uses. By the late 1970s and 1980s personal computers such as the Apple II series and the IBM Personal Computer used standard processors to reduce cost to put a complete computer on top of a desk with a separate monitor. These would find uses in the home as well as in business and industry, and later incorporate graphic user interfaces and powerful networked operating systems such as Mac (Macintosh) and Windows

    Q-7 How to arrange icon on a desktop

    ans:-

    Arrange your desktop icons

    The simplest way to rearrange the icons on your desktop is to simply drag and drop them. You can drag an icon to any location on your desktop.

    Example of desktop icons with pointer dragging Internet Explorer icon

    However, dragging and dropping your icons can lead to icons not aligning in even columns and rows. If you’d rather have neat columns and rows of icons, you can have Windows automatically arrange them for you. Simply right-click your desktop, click Arrange Icons By, and then click Align to Grid. Windows XP does not immediately move your icons. However, the next time you drag an icon, Windows XP will automatically place it into an orderly row.

    Desktop shortcut menu with Arrange Icons By selected and submenu with Align to Grid selected

    To automatically arrange your icons into rows without changing their order, right-click your desktop, click Arrange Icons By, and then click Auto Arrange. Windows XP places your icons into neat rows.

    Q-10 what is print manager?

    ans:-

    Print management can have many definitions. It can be best described as controlling, maintaining and monitoring a printing environment and its productivity levels. Generally, an administrator who engages in print management can manage all the printers on his network. He is provided with real-time status updates on printers and the network on which they operate. In essence, he can manage numerous printers and their environments from one computer. If the administrator were not engaging in printer management activities, he may have to tend to each computer individually.


    Printing management is meant to provide companies and organizations with the tools to make the most of their resources. Space, hardware, software and time — as with deadlines — are all considered when attempting to streamline printing operations. Business owners may choose to outsource their printing management activities and heed the advice of professionals who supply printing management services. For example, a third-party printing management service may assess a company's printing processes and offer suggestions like hardware and software upgrades, the relocation of equipment or the addition of an employee to increase productivity.

    Reports provided by basic print management activities can aid an administrator in keeping on top of what is happening in his printing environment. If an administrator identifies activities that he thinks may contribute to a problem later on, he may take steps to change those behaviors in the printing environment. For instance, an administrator who notices paper being wasted may impose printing limits or require that users utilize options that allow for double-sided printing.

    Print management can also help an administrator in their troubleshooting efforts. Notifications and scripts can be remotely sent through the system to address problems. These problems may range in scope from simple toner and paper changes to system failures. Since small issues are caught before they turn into bigger ones, the need for major technical support can be reduced.

    Besides streamlining operations, printing management can help in saving money and increasing productivity for a company or organization. For example, beneficial print management activities include those that reduce waste and minimize the amount of repairs required to keep a printing environment operational. To truly experience the benefits of print management, changes will have to be made according to a business's specific needs.
