Unit 2. Computer hardware
1. Answer the questions:
– What computer hardware do you know?
– What are the functions of computer hardware components?
2. Read the text and match the words with their translations:
Internal computer hardware components:
Computers need internal components to process and store data delivered by a program or operating system. The user can find them inside the computer case:
CPU – the processor, which CAN BE CALLED the brain of the computer. It performs the basic operations. Its productivity CAN BE DETERMINED BY the quantity of cores, clock speed, the amount of cache memory and the structure of information processing.
Motherboard – a central hub that serves to interconnect information flows between all hardware components
RAM (random access memory) – temporary memory processing in real time. The larger the memory size is, the faster PC will run. RAM data IS CLEARED after switching off the computer.
Hard drive/hard disk drive – physical storage device for permanent and temporary data.
SSD (solid-state drive) – a modern non-volatile solid-state drive that replaced HDD. Its goal is to store data safely even when the computer IS TURNED OFF.
Optic drive – drive that locates in an on-device drive bay. It enables the computer to interact with compact discs.
Heat sink – used for regulation of the temperature inside the computer to avoid overheating of its components.
Graphics processing unit/video card – chip-based device. It processes graphical data. It usually extends functions of the CPU to let the computer work with more complicated tasks.
NIC (network interface card) /network adapter/local are network adapter – circuit board used to connect to an Ethernet network.
USB port – interface that connects the computer with personal electronic devices.
Power supply – component that supplies power to the computer.
Chip – tiny wafer with an embedded electronic circuit. It contains a lot of microscopic electronic components (transistors) which transmit data signals.
3. Discuss the questions:
– How does clock speed affect computer’s performance?
– Why is it important to clean cache memory from time to time?
– What are some popular ways to store data on a PC?
– How do different hardware components work together? Provide some examples.
4. Study the following sentences from the text and choose if the structures in bold are active (объект выполняет действие) or passive (кто-то выполняет действие над объектом):
1) The processor CAN BE CALLED the brain of the computer. (active/passive)
2) The user CAN FIND them inside the computer case. (active/passive)
3) Computers NEED internal components. (active/passive)
4) Its productivity CAN BE DETERMINED BY the quantity of cores. (active/passive)
5) RAM data IS CLEARED after switching off the computer. (active/passive)
6) It CONTAINS a lot of microscopic electronic components. (active/passive)
7) Its goal is to store data safely even when the computer IS TURNED OFF. (active/passive)
5. Study the rules:
Passive Voice
Active Voice: They turn off the computer.
Они выключают компьютер.
Passive Voice: The computer is turned off by them.
Компьютер выключается ими.
Structure: ___+to be (in the correct form) +Ved/3 + by someone
Remember: we need to change subject and object. Plus, we need to change only the verb TO BE in grammar tenses. The main verb will always be in 3 form or with -ed ending.
We use Passive Voice:
– If a subject is a recipient of a verb’s action;
– If we don’t know who does an action or it doesn’t matter for us.
Passive Voice with modal verbs:
Active Voice: People can call the processor the brain of the computer.
Passive Voice: The processor can be called the brain of the computer by people.
6. Match the phrases in Active and Passive Voice:

The laptop ______ (equip) with several sets of expansion memory slots for DDR5 memory. RAM ______ (can reach) up to 128 GB. A massive storage space ______ (can create) with the help of SSD slot – 8 TB. Lightning modes of keyboard and laptop ______ (switch) into various styles. A 17.3 inch, flat display screen ______ (make) with a resolution of 3840 by 2160.The operating system that ______ (use) to control the system – Windows 11.
