A general view that summarizes the subject
Explication
An overview gives a broad summary of a subject without including every detail. The other options describe off-topic information or different concepts.
A memory type that holds temporary data for quick access
Explication
RAM is temporary working memory that lets the CPU access data quickly. Permanent storage is the role of the hard drive, not RAM.
To connect components so they can communicate
Explication
The motherboard is the main board that connects the components and allows them to work together. Electricity comes from the power supply, and long-term storage belongs to the hard drive.
The CPU
Explication
The CPU, or Central Processing Unit, executes instructions and performs calculations. The graphics card displays images, while the case and power supply have different roles.
Before the specific opinion adjective
Explication
A general opinion adjective usually comes before a specific opinion adjective. This is part of the normal adjective order used in descriptions.
General opinion → Specific opinion → Size → Shape → Age → Color → Nationality → Material
Explication
The standard order is General opinion, Specific opinion, Size, Shape, Age, Color, Nationality, then Material. The other sequences place the categories in the wrong order.
Accept data, process it, store it, then produce output
Explication
A computer accepts data, processes it, stores data, and then produces output. This is the basic input-process-store-output cycle.
A personal computer designed for one user at a time
Explication
A microcomputer is also called a personal computer and is designed for one user at a time. Mainframes and supercomputers fit the other descriptions.
Mainframe computer
Explication
Mainframe computers are large, expensive systems designed to support thousands of users simultaneously. Microcomputers are for one user, and minicomputers support far fewer users.
They are the most common type because they are inexpensive
Explication
Microcomputers are described as the most common type because they are inexpensive and designed for one user. The other options describe supercomputers or mainframes.
Prepositions of place
Explication
Prepositions of place describe location relative to other objects, such as in, on, under, behind, and beside. Prepositions of movement describe direction or trajectory instead.
A 3–5 minute conversation about a broken computer and possible solutions
Explication
The speaking task asks for a 3–5 minute conversation about a computer that does not work and the solutions proposed. The other options refer to different activities from the course.
It can interfere with the disk’s magnetization and damage stored data
Explication
A strong magnet can disturb the magnetized regions on a hard disk, which may damage the data stored there. It does not improve CPU speed or RAM capacity.
Diagnoses the problem and suggests possible fixes
Explication
A computer technician identifies why the computer is failing and proposes solutions. The role is diagnostic and supportive, not software design or automatic replacement of all parts.
Store and analyze medical information
Explication
Healthcare computing is used to store and analyze medical information, and to support monitoring and coordination. It does not replace medical staff or stop lab equipment from working.
Monitoring heart rate and blood pressure
Explication
The source states that lab equipment and monitors track heart rate and blood pressure in healthcare. The other options belong to unrelated uses of computers.
Both guests support computer use in everyday life.
Explication
Both is used to refer to two people or things together, so the sentence correctly states that the two guests share the same position. The other options contain agreement or structure errors.
Either guest can speak first.
Explication
Either is used to refer to one of two choices, so it fits with a singular noun here. The other options misuse number agreement or verb form.
Business
Explication
Business computing is used for records, projects, inventory, reports, and communication. Healthcare and science use computers too, but for different purposes.
Security and surveillance
Explication
Security and surveillance uses computer-linked tools such as biometric passports and face recognition. The other fields focus on learning, publications, or organizational management.
A speaker who argues in favor of using computers in everyday life
Explication
The pro-computer guest supports computer use in everyday life. The anti-computer guest is the one who argues against it.
A conversation between a host and two guests discussing benefits and downsides
Explication
The debate is a TV platform discussion built around a host and two guests, one pro-computer and one anti-computer. It is a filmed conversation about benefits and downsides, not a repair interview or a written report.
