Computer Hardware Basics

– any physical device or equipment used in or with a computer system (anything you can see and touch).

External hardware

External hardware devices (peripherals) – any hardware device that is located outside the computer.
– a piece of hardware device which is used to enter information to a computer for processing.
Examples: keyboard, mouse, trackpad (or touchpad), touchscreen, joystick, microphone, light pen, webcam, speech input, etc.
– a piece of hardware device that receives information from a computer.
Examples: monitor, printer, scanner, speaker, display screen (tablet, smartphone …), projector, head phone, etc.

Internal hardware

Internal hardware devices (or internal hardware components) – any piece of hardware device that is located inside the computer.
Examples: CPU, hard disk drive, ROM, RAM, etc.

Computer Software Basics

– a set of instructions or programs that tells a computer what to do or how to perform a specific task (computer software runs on hardware).
Main types of software – systems software and application software.

– a computer program that provides users with tools to accomplish a specific task.
Examples of application software: word processing, spreadsheets, presentation, database management, Internet browsers, email programs, media players, accounting, pronunciation, translation, desktop publishing, enterprise, etc.

– it is designed to run a computer’s hardware and application software, and make the computer system available for use. It serves as the interface between hardware, application software, and the user.

Main functions of system software – allocating system resources, managing storage space, storing and retrieval of files, providing security, etc.
Main types of systems software – operating system, device driver, utility software, programming software, etc.

– a software that controls and coordinates the computer hardware devices and runs other software and applications on a computer. It is the main part of system software and a computer will not function without it.

Main functions of an operating system – booting the computer, managing system resources (CPU, memory, storage devices, printer, etc.), managing files, handling input and output, executing and providing services for application software, etc.
Examples of operating system: Microsoft Windows, Apple iOS, Android OS, macOS, Linux, etc.

– a software program that is designed to control a particular hardware device that is attached to a computer.

The main purpose of device driver – it acts as a translator between the hardware device and operating systems or applications that use it.
It instructs computer on how to communicate with the device by translating the operating system’s instructions into a language that a device can understand in order to perform the necessary task.
Examples of device driver: printer driver, display driver, USB driver, sound card driver, motherboard driver, ROM driver, etc.

– a type of system software that helps set up, analyze, configure, strengthen, maintain a computer and performs a very specific task (e.g. antivirus software, backup software, memory tester, screen saver, etc.).

1 OPERATING SYSTEM An operating system is a group of computer programs that coordinates all the activities among computer hardware devices. It is the first program loaded into the computer by a boot program and remains in memory at all times. In other words, it’s what runs your computer

2 Functions of an Operating system
1. Processor Management duty of processor to different tasks being performed by the computer system. 2. Memory Management allocation of main memory and other storage areas to the system programs as well as user programs and data. 3. Input/output Management coordination and assignment of the different output and input device while one or more programs are being executed.

3 4. File Management the storage of file of various storage devices to another. It also allows all files to be easily changed and modified through the use of text editors or some other files manipulation routines. 5. Establishment and enforcement of a priority system. it determines and maintains the order in which jobs are to be executed in the computer system. 6. Automatic transition from job to job as directed by special control statements. 7. Interpretation of commands and instructions. 8. Coordination and assignment of compilers, assemblers, utility programs, and other software to the various user of the computer system. 9. Facilities easy communication between the computer system and the computer operator (human). It also establishes data security and integrity.

4 Components of Operating system
The kernel, which represents the operating system's basic functions such as management of memory, processes, files, main inputs/outputs and communication functionalities. The shell, allowing communication with the operating system via a control language, letting the user control the peripherals without knowing the characteristics of the hardware used, management of physical addresses, etc. The file system, allowing files to be recorded in a tree structure.

5 4 Types of Operating System
Real-Time Operating System (RTOS) Single-User, Single Task Single-User, Multi-Tasking Multi-User

6 Real time Operating System (RTOS)
Used to run computers embedded in machinery, robots, scientific instruments and industrial systems. Typically, it has little user interaction capability, and no end-user utilities, since the system will be a "sealed box" when delivered for use. An important part of an RTOS is managing the resources of the computer so that a particular operation executes in precisely the same amount of time every time it occurs Examples: Wind River, QNX, Real-time Linux, Real-time Windows NT

7 Single-User, Single Task
OS designed to manage the computer so that one user can effectively do one thing at a time The Palm OS used in many palmtop computers (PDA's) is an example of a single-user, single-task OS 59

8 Single-User, Multi-Tasking
Lets a single user interact with several programs, simultaneously Most popular OS Used by most all PC's and Laptops Examples: Windows, Mac OS, Linux

9 Multi-User A multi-user OS allows many users to take advantage of the computer's resources, simultaneously The OS must make sure that the requirements of the various users are balanced, and that the programs they are using each have sufficient and separate resources so that a problem with one user doesn't affect any of the other users. Examples: Linux, Unix, VMS and mainframe OS, such as MVS

10 Examples of Operating System
Windows 7, Vista, XP Mac OS Unix Linux Embedded Operating system

11 Advantages of Operating System
Easy to use User friendly Intermediate between all hardware and software of the system

12 Disadvantages of Operating System
If any problems affected in OS, you may lose all the contents which have been stored already Unwanted user can use your own system Compatibility
