1[blank_start]System unit[blank_end] is the main hardware component of the computer system. It is the enclosure for all the essential electronic components that make up a computer system.
- ASystem unit
- BSystem board
2[blank_start]Desktops[blank_end] have their system unit in a separate case. This case contains the system’s electronic components and selected secondary storage devices. Input and output devices, such as mouse, keyboard, and monitor are located outside the system unit.
- ADesktops
3[blank_start]Laptops[blank_end] – These are portable computers. Their system units are housed with selected secondary storage devices and input devices
- ALaptops
4[blank_start]Tablets[blank_end] – These portable computers have their system unit located behind the monitor.
- ATablets
5[blank_start]Smartphones[blank_end] – The system unit of these mobile devices are located behind the display screen. There are other mobile computers including wearable computers.
- ASmartphones
6This controls communications for the entire computer system. All devices and components connect to the [blank_start]system board[blank_end], including external devices like keyboards and monitors and internal components like hard-disk drives and microprocessors.
- Asystem board
7The [blank_start]system board[blank_end] acts as a data path and traffic monitor, allowing the various components to communicate efficiently with one another. This is a flat circuit board covered with a variety of different electronic components including sockets, slots, and bus lines.
- Asystem board
8[blank_start]Sockets[blank_end] – Provide a connection point for small specialized electronic parts called chip.
- ASockets
9A chip is also called as [blank_start]integrated circuit[blank_end].
- Aintegrated circuit
10[blank_start]Chips[blank_end] consists of tiny circuit boards.
- AChips
11[blank_start]Sockets[blank_end] are used to connect the system board to a variety of different types of chips, including microprocessor and memory chips.
- ASockets
12[blank_start]Slots[blank_end] – These provide a connection point for specialized cards or circuit boards. These cards provide expansion capability for a computer system.
- ASlots
13These are electrically conductive pathways of the system board. These carry the data from place to place. These provide pathways that support communication among the various electronic components that are either located on the system board or attached to the system board.
- ACables
- BBus Lines
- CWires
- DCircuit
14[blank_start]Central Processing Unit[blank_end] – This contains millions of tiny transistors and pathways (bus lines) that take in data and instructions, process the data according to the instructions, and output the results of the calculations. It is contained on a single chip called the microprocessor.
- ACentral Processing Unit
15[blank_start]Control unit[blank_end] – This manages the flow of data through the CPU. It directs data to and from the other components within the CPU. It directs the movement of electronic signals between memory, which temporarily holds data, instructions, and processed information, and the arithmetic-logic unit. It also directs these control signals between the CPU and input and output devices.
- AControl unit
16This component does the actual processing. It receives data and instructions and delivers a result.
- ACentral Processing Unit (CPU)
- BArithmetic-logic unit (ALU)
- CControl unit
17___________________ are the fundamental math operations.
- ALogical operations
- BArithmetic operations
18___________________ consist of comparisons.
- ALogical operations
- BArithmetic operations
19[blank_start]Registers[blank_end] – These are holding areas for both data and instructions.
- ARegisters
20In a personal computer system, the central processing unit is typically contained on this single electrical component called [blank_start]chip[blank_end].
- Achip
21This type of memory loses its data when NOT continuously supplied with electricity.
- [blank_start]Dynamic[blank_end]- ADynamic
22This container houses most of the electrical components for a computer system.
- [blank_start]system unit[blank_end]- Asystem unit
23Computers can only recognize this type of electronic signal.
- [blank_start]digital[blank_end]- Adigital
24This holds the actual processing in the CPU.
- [blank_start]ALU[blank_end]- AALU
25This provides a pathway to connect parts of the CPU to each other
- [blank_start]bus lines[blank_end]- Abus lines
26This type of memory divides large programs into parts and stores the parts on a secondary storage device.
- [blank_start]virtual memory[blank_end]- Avirtual memory
27Which is the other term for the mainboard or motherboard?
- [blank_start]system board[blank_end]- Asystem board
28Also called as volatile memory. This memory does not retain its data unless it is electrically refreshed.
- [blank_start]Dynamic memory[blank_end]- ADynamic memory
29Also called as non-volatile memory. Memory that retains its data without electricity being constantly applied.
- [blank_start]Static memory[blank_end]- AStatic memory
30It is a holding area for data, instructions, and information. It is contained on chips connected to the system board.
- [blank_start]Memory[blank_end]- AMemory
31These are chips that holds the program (sequence of instructions) and data that
the CPU is presently processing.
- [blank_start]ram[blank_end]- Aram
32It is a high-speed holding area for frequently used data and information.
- [blank_start]Cache memory[blank_end]- ACache memory
33It is used to expand memory.
- [blank_start]Dual in-line memory module[blank_end] ([blank_start]DIMM[blank_end])- ADual in-line memory module
- BDIMM
34This offers a combination of the features of RAM and ROM. Like RAM, it can be updated to store new information. Like ROM, it does not lose that information when power to the computer system is turned off.
- [blank_start]Flash Memory[blank_end]- AFlash Memory
