MEMORY UNITS OF COMPUTER Hello Readers, Here we are representing to you all about "Memory units of computer" which can be very important for you... DATA REPRESENTATION -   Memory Units: Binary Number = 0,1 (Machine Language) 4 bit = 1 nibble 8 bit = 1 byte 1024 B = 1 KB (Kilo Byte) 1024 KB = 1 MB (Mega Byte) 1024 MB = 1 GB (Giga Byte) 1024 GB = 1 TB (Tera Byte) 1024 TB = 1 PB (Peta Byte) 1024 PB = 1 XB (Exa Byte) 1024 XB = 1 ZB (Zeta Byte) 1024 ZB = 1 YB (Yota Byte) bit < Byte < KB < MB < GB < TB < PB < XB < ZB < YB Data: The information you put into the computer is called  Data. Information of a computer is stored as   Digital Data. There are two basic types of Data, which are stored and processed by the computer:     1.Character      2. Number 1 Character = 1 Byte 1 Number = 2 Bytes -1 Number = 4 Bytes Bits (b): The term Bit is nothing but the contracted form f Binary Digit. A

Introduction To Computer what is computer? A computer is a programmable machine designed to perform arithmetic and logical operations automatically and sequentially on the input given by the user and gives the desired output after processing. OR COMPUTER is an electronic device that accept input through keyboard, store it in its memory by performing mathematical and logical operation and finally executes the program and displays the result.  OBJECTIVES After going through this lesson you would be able to:  familiarise yourself with characteristics of computers  identify the basic components of a computer  explain the importance of various units of a computer  differentiate between system software and application software  explain the importance of operating system  get acquainted with open source  appreciate the need of computer security CHARACTERISTICS OF COMPUTERS: The characteristics of computers that have made them so powerful a
