Читать книгу English for system administrators - Светлана Алексеевна Губарева - Страница 6

1. Look at the word below and complete the scheme with the information that you know:

2. Discuss the questions:

1) How important are severs to companies?

2) What kind of data do servers store?

3) Can you name any characteristics that a server might have?

4) What security measures do you think a company need to take when dealing with servers?

5) What problems may occur if a server doesn’t work correctly?

3. Read the dialogue and put the words in brackets into correct order:

Kathrine – office worker

Jack – system administrator

K.: Hi, Jack. 1._____ (you/sorry/bother/to), but Leon said that only you could help me. 2._____ (5 minutes/I/may/of your time/you/ask/for)?

J.: Ok.

K.: Thanks! 3._____ (you/I/ ask/wanted to/about) servers we’re using at work.

J: Well, we have one physical server on-premise and also we use OpenStack VMs for some applications.

K.: 4._____ (I/wondering/was/if you/me/could/to/help) explain the difference between a physical server and an OpenStack VM.

J.: Sure. A physical server is a sort of hardware that can be touched and seen, you know. It processes data, RAM and disk space. Moreover, this server hosts virtual machines. In our company all VMs were created by OpenStack software. Such virtual machines we call instances.

K.: That’s interesting. 5._____ (understand/If/correctly/I), we can create a lot of instances with the use of OpenStack to run various applications?

J.: Exactly. Furthermore, each instance can be allocated its own resources like CPU, memory, and storage. We can even assign them to specific VLANs.

K.: Pardon? 6._____ (I/catch/didn’t) what VLANs are.

J.: A VLAN is a Virtual Local Area Network. It’s used to separate networks or network segments logically without needing two physical networks. This helps in efficient utilization of resources within an organization’s network infrastructure. So, it’s like having different groups of logical switches so we can control LAN traffic depending upon users or applications you wish to provide connectivity to.

K.: I see. You also mentioned RAM. How can it affect server’s performance?

J.: The amount of RAM will determine how many programs you can run simultaneously and how fast it could be. If there isn’t enough RAM, the system will slow down or crash because it doesn’t have enough available memory to handle all the requests.

K.: 7._____ (got/I/it). And what about security?

J.: Don’t worry. We use firewalls, encryption methods, antivirus software, and regular maintenance updates to keep our servers secure.

K.: 8._____ (now,/That’s/you/clear/thanks). I have one more question: how do we ensure that our server is always operating efficiently?

J.: It’s easy. We monitor its performance regularly, analyse usage patterns, and make adjustments which are needed to optimise its speed and reliability.

K. All right. 9._____ (Thanks/all this/ for explaining).

J.: No problem. See you!

9. Read the sentences and choose the functions of grammar tenses in them:

10. Study the rules:

Future Simple and be going to

We use Future Simple:

– to talk about predictions based on our opinion (I think it will be better to upgrade it as soon as possible.);

– to make spontaneous decisions (Ok, we will try to call them.);

– to make promises (I will do everything to prevent a server crash.).

We use be going to:

– to talk about our plans (I am going to do 3 tasks today);

– to talk about predictions based on facts (We noticed some problems with VM’s resources, so we are going to optimize it.).

11. Put the verbs into the correct future grammar forms:

1. (our company optimise) the website as we planned?
