COMPUTER IN ENGLISH

A computer is an electric device that is used to perform repetitive calculations at very high speed. The computer acts as a data processing device and also stores large amounts of data.

This data could be text, pictures, voice numbers, photographs and other types of information that are used by humans in their day-to-day operations. Life cannot be imagined without computers.

In fact, the new millennium is the era of computers and its associated techniques, commonly known as Information Technology (IT). Computers help the school children learn new techniques of study, graphic designs, games and other useful educational applications.

They help the college students in preparing reports. They help the office executives in accounts, software development, sale invoicing and manufacturing. They help the libraries in the efficient management of their operations. They run the factories and equipment. They control the satellites and nuclear weapons. They help the young and the old through Internet sites. They are, in fact, indispensable as every operation of human life is incomplete and inefficient without them. As school-going students, we must learn computers. Computers are available in various configurations.

For learning computer operations a computer with 166 MHz speed (Known as the CUP speed), an HDD of 1.2 MB storage capacity and RAM of 32 MB is needed. These elementary computers would help the school students learn LOGO, BASIC, Windows 95 (the operating system in usage nowadays), games, various lectures related to the syllabi and internet operations.

A student would do well to learn the basics of computer operations. In his or her school, he or she can join evening classes for getting advanced level training. Computers are easy to learn and are student-friendly machines.

They improve the efficiency of the student and make him more knowledgeable. They help him or her in his or her education, mental development and entertainment. In the times to come, all the students would either have their own computers or would have free access to them.

Computerisation in banks is complete and most of the factories, offices, colleges and schools have advanced computer systems. The latest professing speed of the computer is 533 MHz but this computer is costly.

A good computer, which would serve the purpose of the student, costs Rs. 30000 only. And this cost would come down in the years to come. Students should adopt computers in their educational teaming and for their mental development

Answer: These numbers represent the characteristics of the computer and they are units of measurement

LESSON 20: Reporting incidents. Reporting a security incident.

Task 1: Write an incident report to your manager, the solution and who was responsible for that

Dear John,

Since you requested in our recent line management meeting for me to inform you of any issues, I’m writing to tell you about a recent incident. Last week, after experiencing some difficulties with the order processing system, tensions arose in the team and a confrontation occurred between two team members.

I’ve outlined what led to this incident below:

1. 
   There was a system update that we weren’t expecting last week. The update slightly changed the interface menu. Everything is still there but people have said it’s not easy to find some of the menu items they’re looking for.
   

2. 
   There seems to have been a period of time after the update that new entries weren’t being saved. This led to some work being lost. We worked overtime to catch up on everything and all orders have been processed. But as a consequence there was a general feeling of pressure and tiredness in the team.
   

As a result of these challenging circumstances there was some tension, leading to a disagreement between Johann and Maria. Johann lost his temper and made some inappropriate remarks to Maria.

I met with them both in order to reflect on and resolve the conflict. Johann has apologised for his behaviour and he realises that Maria could have chosen to start disciplinary proceedings. They have worked together on a plan to improve communication and therefore alleviate tensions within the team.

I’ve also asked our colleagues in the IT department to run a training session for us all on how to best use the system in light of the recent software upgrades.

There’s no specific action for you to take, but I felt it important that you’re kept in the loop.

I’ll keep you posted.
