Memori

Memori adalah salah satu bagian dalam komponen komputer. Memori bagi orang awam disebut dengan RAM. Memori ini berguna untuk mengatakan pada komputer apa yang harus dilakukan untuk melakukan suatu perintah.
Memori menyimpan berbagai bentuk informasi sebagai angka biner. Informasi yang belum berbentuk biner akan dipecahkan (encoded) dengan sejumlah instruksi yang mengubahnya menjadi sebuah angka atau urutan angka-angka. Sebagai contoh: Huruf F disimpan sebagai angka desimal 70 (atau angka biner ) menggunakan salah satu metode pemecahan. Instruksi yang lebih kompleks bisa digunakan untuk menyimpan gambar, suara, video, dan berbagai macam informasi. Informasi yang bisa disimpan dalam satu sell dinamakan sebuah byte.
Secara umum, memori bisa ditulis kembali lebih jutaan kali - memori dapat diumpamakan sebagai papan tulis dan kapur yang dapat ditulis dan dihapus kembali, daripada buku tulis dengan pena yang tidak dapat dihapus.
Ukuran masing-masing sel, dan jumlah sel, berubah secara hebat dari komputer ke komputer, dan teknologi dalam pembuatan memori sudah berubah secara hebat - dari relay elektromekanik, ke tabung yang diisi dengan air raksa (dan kemudian pegas) di mana pulsa akustik terbentuk, sampai matriks magnet permanen, ke setiap transistor, ke sirkuit terpadu dengan jutaan transistor di atas satu chip silikon.

Computing

Computing the distance between the thirty-first and forty-fifth degrees, it amounts to nine hundred and seventy-three common miles; computing it from thirty-one to forty-two degrees, to seven hundred and sixty-four miles and a half..The term computing is synonymous with counting and calculating. Originally, people that performed these functions were known as computers. Today it refers to a science and technology that deals with the computation and the manipulation of symbols. "Computing" also refers to the operation and usage of computing machines, the electrical processes carried out within the computing hardware itself, and the theoretical concepts governing them (computer science). Crooks and his companions had been completely disheartened by this retrograde march through a bleak and barren country; and had found, computing from their progress and the accumulating difficulties besetting every step, that it would be impossible to reach Henry's Fort and return to the main body in the course of the winter

Hardware

Hardware implies permanence and invariability. Software or programming can easily be varied. You can put an entirely new program in the hardware and make it create an entirely new experience for the user. You can, however, change the modular configurations that most computers come with by adding new adapters or cards that extend the computer's capabilities.Computer is so called in contrast to computer hardware, which encompasses the physical interconnections and devices required to store and execute (or run) the software. In computers, software is loaded into RAM and executed in the central processing unit. At the lowest level, software consists of a machine language specific to an individual processor

Software

Software is the programs that run on a computer. Explanation: Software is made up of instructions that tell the computer what to do. It is stored on disks in bits and bytes. ClarisWorks and Kid Pix are examples of software. "Please load the ClarisWorks software on the computer." Computer software is a general term used to describe a collection of computer programs, procedures and documentation that perform some task on a computer system. The term includes application software such as word processors which perform productive tasks for users, system software such as operating systems, which interface with hardware to provide the necessary services for application software, and middleware which controls and co-ordinates distributed systems.

Programs

Programs can be characterized as interactive or batch in terms of what drives them and how continuously they run. An interactive program receives data from an interactive user (or possibly from another program that simulates an interactive user). A batch program runs and does its work, and then stops. Batch programs can be started by interactive users who request their interactive program to run the batch program. A command interpreter or a Web browser is an example of an interactive program. A program that computes and prints out a company payroll is an example of a batch program. Print jobs are also batch programs. A Program may not be sufficiently complete for execution by a computer. In particular, it may require additional software from a software library in order to be complete. Such a library may include software components used by stand-alone programs, but which cannot work on their own.
