What is Cell? (in computer) In a computer, we use various kinds of spreadsheet, specially in Microsoft excel. A cell is an intersection between a row and a column on a spreadsheet In spreadsheet applications, a cell is a box in which you can enter a single piece of data. The data is usually text, a numeric value, or a formula. The entire spreadsheet is composed of rows and columns of cells. A spreadsheet cell is analogous to a field in database management systems. Individual cells are usually identified by a column letter and a row number.

In DVD, a cell is a unit of playback of real-time data. Each cell is identified by a unique set of numbers.
In Short, cell is called cellular phone.
What is Cell? (in biology)
Cell Biology is the sub discipline of biology that studies the basic unit of life, the cell. A cell is the very smallest unit of living matter. Cells are the structural and functional units of all living organisms. Some organisms, such as bacteria, are unicellular, consisting of a single cell.
Other organisms, such as humans, are multicellular, or have many cells—an estimated 100,000,000,000,000 cells! Each cell is an amazing world unto itself: it can take in nutrients, convert these nutrients into energy, carry out specialised functions, and reproduce as necessary. All living things including plants and animals are made up of cells. Cells are made of atoms, which are the smallest units of matter.
Important Events of Cell Biology
There have been many significant events in the history of the development of the field of cell biology as it exists today. Here are some of the major events:• 1655 - Robert Hooke gives the first description of a cork tree cell.
• 1674 - Leeuwenhoek views protozoa. • 1683 - Leeuwenhoek views bacteria.
• 1831 - Robert Brown was first to identify the nucleus as an important cell component.
• 1838 - Schleiden and Schwann introduce what would become the Cell Theory.
• 1857 - Kolliker describes mitochondria.
• 1869 - Miescher isolates DNA for the first time.
• 1898 - Golgi discovers the Golgi apparatus.
• 1931 - Ruska builds the first Transmission Electron Microscope.
• 1953 - Watson and Crick propose the structure of DNA double-helix.
• 1965 - First commercial Scanning Electron Microscope produced.
• 2003 - Human genome DNA sequence draft completed.
I conclusion, I hope that every learner will clear about what is cell and type of cell after reading this article.
