What are the characteristics of image based and color based operating system?

Based on the interface, operating systems are divided into two categories, namely:

(i) Text or character-based operating system

(ii) Image-based operating system.

Text or letter-based operating systems: In text-based operating systems, commands are executed by typing them in the command prompt according to their structure. Commands are written using letters, words, numbers, symbols, etc. To work in this system, the user needs to know the commands and syntax in advance and work by writing commands according to the syntax. Being color based this operating system is difficult and boring to work with. Commands have to be typed by keyboard only. A. Network, Internet system is not working. This system requires relatively little memory to operate, cannot run multiple programs simultaneously, supports only one user, and requires the use of a keyboard to move the cursor. No pictures, images or icons can be used in this command. Examples: MS-DOS, TOS, BOS, UNIX et cetera.


Characteristics of text or character-based operating systems:


(1) All commands have to be typed to work.

(ii) Cannot run more than one program simultaneously.

(iii) Supports only one user at a time.

(iv) All operations including moving the cursor should be done using the keyboard.

(v) File copy, delete and move must follow the path according to the specified syntax.

(vi) Networking or Internet systems are not functional in text or character-based operating systems.

(vii) To operate the computer by memorizing commands and syntaxes.

(viii) No visible pictures, images or words or icons may be used to give commands.


Graphical Operating System: Operating a computer by applying commands through graphics or images is called Graphical User Interface (GUI) operating system. It contains graphical images and pull-down menus for various tasks. Commands can be applied with either mouse or keyboard. It does not require memorizing commands and syntaxes. This system is relatively slow and requires more memory. Working in this operating system is easy and convenient. Networking, sharing, and internet systems are very effective. Microsoft Corporation developed image based operating system in 1985. The first and second versions were not very popular, but later in 1990, the 3.0 version became popular. Next came version 3.1 and the following year version 3.3. In 1995, the Windows 95 operating system with advanced graphics, networking and Internet facilities came into the market. Windows 98, Windows NT, Windows XP, and Windows 7 came in the market as Windows 95 and advanced versions.


Features of image-based operating system --


(i) Graphical operating systems have the advantage of using on-screen overlapping windows.

(ii) Commands can be executed with either mouse or keyboard.

(iii) It does not require memorization of commands.

(iv) It contains visual images for the task like buttons, icons, menus etc. As a result, work can be done quickly and easily

(v) Pull-down menu dialogue boxes, selection lists, etc. are available for ease of work, in which even less skilled users can work by looking at images or icons.

(vi) Networking, file sharing, internet etc. are easier and more effective in image-based operating systems.

(vii) Multiple programs can be run simultaneously.

(viii) supports one or more users at the same time.

What should the processor look at?

The things that we all should keep an eye on are the processor or not; 1. Clock speed 2. Number of course 3. cache memory 4. FBS 1. Clock Speed: It is also called GH2. All processors are written on. Clock speed means how fast your computer can work. That's what this signal means. The speed of the processor is known through this clock speed, how fast the calculation can be done. 2. Number of Cores: The more cores the processor has, the faster the processor can work. If I give an example to explain the matter, I hope you can understand it very easily. Suppose if a person had many hands, then he could do many things at the same time. That is, if we go to the market and buy a smartphone, then we will see what the configurations of the phone are. If we look closely at the configuration of the smartphone, we will see that Dual Core Processor, Quad Core Processor, Octa core processor, Hexa core processor, Deca core processor. This means that the dual core processor has two arms or cores, ...

What is transmission media? Introduction to different types of data transmission cables

Transmission media: When a PC communicates or wants to communicate with another PC, it has to take the help of some transmission media. The most commonly used media in the network are twisted pair cable, coaxial cable, fiber optic cable. Nowadays, the use of optical fiber is increasing greatly. Radio wave, microwave and infrared technologies are prominent among wireless media. Among these mediums, optical fiber has the highest data transfer speed. The type of medium used in a network depends on the type and location of that network. The connection system for exchanging information between the sender and the remote receiving end is called a channel. The means or methods used to implement the channel are called media. such as-- (i) Cable or wire. (ii) Common telephone lines. (ii) Radio waves. (iv) Microwave. (v) Geo-satellite systems etc. Cable or Wire: Cable is an important medium in data communication. Cables are generally used for data transfer over short range networking such as LAN...
