Difference Between RAM and ROM

Difference Between RAM and ROM Points : difference between ram and rom, ram vs rom
Difference Between RAM and ROM
RAM
ROM
1.RAM is larger and busier of the two. When program and data are joined into the computer they are put in RAM.ROM holds the built-in operating system, basic input output system (BIOS) and utility programs responsible for carrying out computers basic functions.
2.As the name implies, the memory location in RAM can be accessed randomly.These are normally accessed automatically when the computer is turned on.

Memory Unit and its two major types

Memory Unit and its two major types Points : define memory unit and its two major types, read only memory (rom), random access memory (ram) Memory Unit Memory unit is the place where the computer program and data re stored during processing. It is the area, through which all the data which is input into or output of the CPU mist pass. ft is monitored by OU which keeps track of every thing in the storage. It is a random access device, which consists of thousands upon thousands of storage locations, each of which can be directly reached by the CU. Each storage location is distinguished by the address.

It is divided into two parts.

CPU and its different units

CPU and its different units Points : cpu and its different units, central processing unit (cpu), ? arithmetic and logic unit (alu), centro unit (cu), memory unit (mu), Central Processing Unit (CPU) Central Processing Unit (CPU) is the brain of computer system. We use CPU to control all input and output connections inside arid outside of computer to produce correct answers for the user. it controls and supervises all the units in a computer. It takes information from the input unit and from the memory and uses it according to the instructions already given to the computer. From functional point of view CPU consists of three parts.

Major Function of Input and Output Devices

Major Function of Input and Output Devices Points : major function of input and output devices Major Function of Input Device
  • These are physical equipments that read or translate data consisting of alphabets, number or other symbols into electronic impulses, which can be understood by the computer.
  • The purpose of input devices is to pass information into the memory unit of the CPU.

Functional Units of Computer

Functional Units of Computer Points : functional units of computer, input unit, central processing unit (cpu), function of a cpu:, output unit, hard copy and soft copy Functional Units of Computer A micro computer consists of several components, each containing mechanical and electronic equipments. There are three basic components of a computer.
i. Input unit
ii. Central Processing Unit
iii. Output Unit

Difference Between Internal And External Memory

Difference Between Internal And External Memory Points : difference between internal and external memory, comparision between internal and external memory
Difference Between Internal And External Memory
Internal Memory
External Memory
1.Internal memory is also known as primary storage or main memory.External memory is also known as secondary, Auxiliary or backing storage.
2.It is volatile in nature in case of RAM but ROM is non-volatile.It is non-volatile in nature.
3.It is connected by inserting chips into sockets in case of RAM while ROM is built in into the computer.They are connected by data cable and power cable with the computer.

Difference between Serial ports and Parallel ports

Difference between Serial ports and Parallel ports Points : difference between serial ports and parallel ports, define ports. compare and contrast: serial ports and parallel ports Ports A ports is a socket at the back of a computer used to plug-in various devices. Personal computers have various types of ports. Internally; there are several ports for connecting disk drives, display controllers and keyboards. Externally, personal computers hive ports for connecting modems, printers, scanner and other peripheral devices.
