A. Unit One:- introduction
What is computer?
- A computer is an electronic device that manipulates information, or data.
- It has the ability to store, retrieve, and process data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web.
- You can also use it to edit or create spreadsheets, presentations, and even videos.
- ኮምፒተር ምንድን ነው?
- ኮምፒውተር ማለት መረጃን የሚጠቀም ኤሌክትሮኒክ መሣሪያ ነው
- መረጃን የማከማቸት ፣ የማምጣት እና የማካሄድ ችሎታ አለው።
- ሰነዶችን ለመተየብ(ለመፃፍ) ፣ ኢሜል ለመላክ ፣ ጌሞችን እና ጨዋታዎችን ለመጫወት እና እንዲሁመ ድህረገፆችን ለማሰስ ኮምፒተርን መጠቀም እንደሚችሉ አስቀድመው ያውቁ ይሆናል።
- እንዲሁም የተመን ወይም ሂሳብ ስራወችን ለመስራት ፣ዉስብስብ ና ብዛት ላቸዉን መረጃወች ለመተንተን ፣ ቪዲዮዎችን ና ድምፆችን ለማየት ለመስማት እንዲሁም ለማዘጋጀት ፣ ለመፍጠር ሊጠቀሙበት ይችላሉ።
2. የኮመፒዩተር ትዉልድ (COMPUTER GENERATION)
1. FIRST GENERATION: VACUUM TUBES (1940-1956)
- The first computer systems used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. These computers were very expensive to operate and in addition to using a great deal of electricity, the first computers generated a lot of heat, which was often the cause of malfunctions.
- First generation computers relied on machine language, the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. It would take operators days or even weeks to set-up a new problem. Input was based on punched cards and paper tape, and output was displayed on printouts.
- The UNIVAC and ENIAC computers are examples of first-generation computing devices. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951.
