Answers
Answer:
1. Hardware refer to the physical parts of a computer that you can see and touch.
2. GUI (Graphical User Interface):
GUI users have Windows that allow a user to work, view, control, and manipulate multiple programs and folders at the same time.
In GUI multiple tasks can run simultaneously at a time.
CUI (Character User Interface):
CUI does not offer the same ease and ability to work with multiple programs at once on one screen
Only one task can be executed at a particular point of time in CUI.
3. GUI requires more RAM to run .
4. a). graphical user interface
b). Character User Interface.
c). real-time operating system
5. Following are the disadvantages of GUI Interface: ➨It uses more computer memory as the aim is to make it for user friendly and not resource optimized. As a result it can be slow on older machines. ➨GUI becomes more complex if user needs to communicate with the computer directly
6. I). Multi-user operating system allows more than one user to use the same computer at the same time or at different times. Some Operating Systems, which fall in this category are: Windows 2000, Windows NT, Windows XP, Windows Vista, Windows 7, Windows 8, Windows 8.1, Linux, Unix. Windows 2000 was the first version of Windows, which allowed creation of several user accounts on a single machine.
ii) These operating systems allow different parts of a software program to run simultaneously. The feature of multi-threading can delay the execution response of certain processes. For example, if a Game server is hosted on LAN, then all players connecting to that server will utilise different parts of the same game at the same time. All resources will be utilised from the server machine, which can be a performance degrading factor. The common examples of such operating systems are: Windows NT/2000, Windows XP, Windows 7, Windows 8, Windows 8.1, Unix, Linux, etc.
iii). There are two types of Real Time Operating Systems:
Hard Real-time systems — These systems guarantee that critical tasks are completed in time.
Soft Real-time systems — These systems are less restrictive. Examples are: Undersea exploration, Planetary rovers, and Virtual reality.
iv). Distributed operating system runs on a set of computers that are located in different geographical areas, interconnected by a network. It controls these interconnected systems and makes them appear as a single computer. It allows all the linked machines to access data and software, and the process takes over the common network from different computers, irrespective of their location on the globe.
7. A formula is an expression telling the computer what mathematical operation to perform upon a specific value.
example of a Microsoft Excel formula =SUM(A$1:A$3), which adds the total of cells A1, A2, and A3. In this formula, SUM is the function of the formula.
8. In 2008, he left Facebook to co-found Asana with Justin Rosenstein. In March 2011, Forbes reported Moskovitz to be the youngest self-made billionaire in history, on the basis of his 2.34% share in Facebook.
Net worth US$19.2 billion (March 2021)
9. ICS was a feature of Windows 98 SE and all versions of Windows released for personal computers thereafter.
Operating system: Microsoft Windows
Other names: ICS
10. the key combination which is used to get the total of adjacent cells is "Alt+=".
Explanation:
1.Hardware refer to the physical parts of a computer that you can see and touch.
2. Ans-GUI (Graphical User Interface)
GUI users have Windows that allow a user to work, view, control, and manipulate multiple programs and folders at the same time.
CuI–(Character user interface)
CUI does not offer the same ease and ability to work with multiple programs at once on one screen.
3. Applications requires more RAM to run .
4. Write the full form of the following:
a.GUI - Graphical user interface
b.CUI - Character user interface
c.RTOS -
5.Ans-Following are the disadvantages of GUI Interface:
➨It uses more computer memory as the aim is to make it for user friendly and not resource optimized. As a result it can be slow on older machines.
➨GUI becomes more complex if user needs to communicate with the computer directly.
6. write short note on the following:
i. A multi-user operating system (OS) is one that can be used by more than one person at a time while running on a single machine. Different users access the machine running the OS through networked terminals.
ii .Multithreading is the ability of a program or an operating system process to manage its use by more than one user at a time and to even manage multiple requests by the same user without having to have multiple copies of the programming running in the computer.
iv . Distributed operating system-A distributed operating system is system software over a collection of independent, networked, communicating, and physically separate computational nodes. They handle jobs which are serviced by multiple CPUs. Each individual node holds a specific software subset of the global aggregate operating system.
7. Ans- Formula is a short notation for any derivation or a expression.
F=ma
Here f equals to m multiplied by a is a short notation for force equals mass into acceleration.
