(a)Define the memory unit of a computer?

The memory unit is the most important part of a computer. Memory units are used to store data and instructions that are currently in use. It is necessary to know about all the memory units of the computer. First, we understand what memory units are:

"Memory unit is the amount of data that can be stored in the storage unit. Storage capacity is expressed in terms of bytes."

(b)What is Bit?

A bit is also called binary digit or binary number system. A computer can only understand the binary digit. Binary digits consists of values (0,1). A bit at a time can store only one of these two binary values either 0 or 1.0 shows the passive state of the signal while 1 shows the active state of the signal.

(c)What is Nibble?

A collection of four bits is called Nibble.

(d)What is Byte?

A collection of 8 bits is called Byte. Bytes are stored digitally (tape, disc), etc to define the amount of data on storage. Each keyboard character is stored as a Byte.

(e)What is Word?

A computer word is a combination of a fixed number of bits. A computer usually stores data in the form of computers.

imp MCQs: Smallest measuring unit of memory is Bit(0,1).

(f)Define the Table of memory units of a computer?

Transport Layer

  Topic Outline Transport Layer TCP Function of TCP UDP Difference between TCP and UDP Transport Layer The Transport layer is essentially responsible for delivering data to the appropriate application on the host computer. It receives requests from the application layer protocols and passes them down to the internet network layer. Two most commonly used transport layer protocols are the connection TCP and connection UDP. TCP  Transmission Control Protocol End to End communication for user processes. Processes can communicate in a simple stream of binary data. Each byte of data will arrive in the order it was sent. If some part of the data cannot be received this will be made explicit by an error being passed to the user code. Functions of TCP   (1) Data Transfer TCP transfer a continuous stream of bytes. TCP itself decides how to segment the data and it may forward the data at its own convenience. (2) Reliability TCP assigns a sequence number to each byte transmitted and ...

Types of database

Topic Outline Types of Database Object-Oriented Database Centralized Database Decentralized Database Distributed Database Hierarchical Database Personal Database Cloud Database Multi-Dimensional Database Operational Database Relational Database  1:Object-Oriented Database Object-oriented database stores data in the form of objects. An object is an item that can contain data and functions. For example, an object employee may contain data about an employee such as Employee ID, Name, Address, Phone Number, etc. It may also contain functions to process the data such as printing the record of an employee, calculating salary, etc. Characteristics The object-oriented data model must be able to provide complex object representation. The object-oriented data model must be extensible. It means it provides support for defining new data types and methods. The object-oriented data model must support encapsulation or information hiding. The object-oriented data model must exhibit inheritance. In...

  Topic Outline Display devices Types Cathode Ray Tube Flat Panel Display Emissive Display LED OLED Gas Plasma Non-Emissive Display LCD A display device is an output device. It is used to represent information in the form of text, graphics, images, and video. The display for a desktop computer is a monitor. Mobile computers and devices integrate the display in the same physical case. Some displays have touch screens such as mobile phones and laptops etc. The output displayed by a display device is called soft copy. Display devices are available in different sizes. For example When we write any document on the computer, it is a soft copy of the document. When we get a print of this document, it is a hard copy of the document. Types Types of display devices are as follows. (1) Cathode Ray Tube A cathode-ray tube creates an image on the screen by using a beam of electrons. Cathode ray tube consists of one or more guns. These guns fire a beam of electrons inside the screen. The monitor...
