Option “A” is correct. The computer does its primary work in a part of the machine we cannot see, a control center that converts data input to information output. This control center, called the central processing unit (CPU), is a highly complex, extensive set of electronic circuitry that executes stored program instructions.
2.
USB stands for ________?
a.
b.
c.
d.
Option “A” is correct. USB, short for Universal Serial Bus, is a standard type of connection for many different kinds of devices. Generally, USB refers to the types of cables and connectors used to connect these many types of external devices to computers.
3.
ALU stands for ________?
a.
b.
c.
d.
Option “B” is correct. An arithmetic logic unit (ALU) is a combinational digital electronic circuit that performs arithmetic and bitwise operations on integer binary numbers. This is in contrast to a floating-point unit (FPU), which operates on floating point numbers. An ALU is a fundamental building block of many types of computing circuits, including the central processing unit (CPU) of computers, FPUs, and graphics processing units (GPUs). A single CPU, FPU or GPU may contain multiple ALUs.
4.
CPU stands for ______ ?
a.
Central Performance Unit
b.
c.
d.
Option “D” is correct. A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.
5.
Which of the following holds the ROM, RAM, CPU?
a.
b.
ALU
c.
d.
Option “C” is correct. The Motherboard is the main circuit board for the computer, containing both soldered, non-removable components along with sockets or slots for components that can be removed. The motherboard holds the CPU, RAM and ROM chips, etc.
6.
What technology of memory is Cache RAM usually?
a.
b.
Flash
c.
SRAM
d.
EEPROM
Option “C” is correct. A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for main memory. Memory caching is effective because most programs access the same data or instructions over and over.
7.
Where is computer’s BIOS stored?
a.
DRAM
b.
Flash
c.
SRAM
d.
Option “B” is correct. BIOS (Basic Input Output System) software is stored on a non-volatile ROM chip on the motherboard. In modern computer systems, the BIOS contents are stored on a flash memory chip so that the contents can be rewritten without removing the chip from the motherboard.
8.
Where does your PC store your programs when the power is off?
a.
DRAM
b.
Cache
c.
ROM
d.
Option “D” is correct. A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage and one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data even when computer powered off.
9.
What is PCI(Peripheral Component Interconnect)?
a.
b.
c.
d.
Option “B” is correct. PCI (peripheral component interconnect) is an interface standard for connecting high-speed components. Every desktop PC motherboard has a number of PCI slots you can use to add GPUs, RAID cards, Wi-Fi cards or SSD (solid-state drive) add-on cards.
10.
Which company is not a microprocessor manufacturer?
a.
IBM
b.
c.
Microsoft
d.
Intel
Option “C” is correct. Microsoft currently uses Intel-based processors for the majority of its Azure cloud services, and most of the company’s Surface lineup run on Intel chips, too. We reached out to Microsoft to comment on the rumors, and the company didn’t deny them.
