Explanation: A firewall filters incoming and outgoing network traffic according to security rules, blocking many unauthorized connections.

• A. Memory cell
• B. Chip
• C. Gate
• D. Integrated circuit

Explanation: A memory cell is the basic storage element in a digital circuit and holds a bit of information.

• A. the same thing as a programmer
• B. a program which translates source program into object program
• C. key punch operator
• D. a person who computes source programs

Explanation: A compiler translates a program written in a source language into object code or another lower-level form that the computer can use.

• A. Copying a document from memory to a storage medium
• B. Making changes to a document's existing content
• C. Changing the appearance, or overall look, of a document
• D. Developing a document by entering text using a keyboard

Explanation: Saving copies a document from working memory to a storage medium such as a disk or solid-state drive so it can be retrieved later.

• A. RAM
• B. CD-ROM
• C. ROM chip
• D. All of these

Explanation: The computer's startup or boot instructions are stored in non-volatile firmware memory, traditionally a ROM chip.

• A. Memory
• B. Control Unit
• C. Register Unit
• D. Accumulator

Explanation: Main storage refers to the computer's primary memory, so it is also called memory.

• A. DASI
• B. ASCII
• C. BASCII
• D. EPROM

Explanation: ASCII, or American Standard Code for Information Interchange, assigns standard numeric codes to letters, digits, punctuation, and control…

• A. Function keys
• B. The numeric keypad
• C. Ctrl, shift and Alt
• D. Arrow keys

Explanation: The numeric keypad groups number keys together, allowing rapid entry of numerical data.

• A. RAM
• B. BIOS
• C. CMOS
• D. ROM

Explanation: BIOS is firmware stored in ROM or flash memory that runs when the computer starts and initializes the hardware before loading the…

• A. WAN
• B. LAN
• C. CAN
• D. DAN

Explanation: A WAN connects LANs across cities, countries, or other large geographic areas, making it suitable for geographically separated offices.

• A. Complier
• B. Debugger
• C. Translator
• D. Linux

Explanation: Linux is an operating system that manages hardware resources and provides services for application programs.

• A. Robotic computers
• B. Servers
• C. Mainframes
• D. Embedded computers

Explanation: Embedded computers are specialized computing units built into devices such as cars, thermostats, appliances, and medical equipment.

• A. Pascal
• B. Napier
• C. Leibnitz
• D. Babbage

Explanation: Gottfried Wilhelm Leibniz developed the Stepped Reckoner in the 17th century, a mechanical calculator capable of addition, subtraction…

• A. Utilities
• B. System diagnostics
• C. System analysis
• D. System software

Explanation: System diagnostics are programs or tools that test hardware and software components to identify faults or overall system malfunction.

• A. minutes
• B. Milliseconds
• C. Megabytes
• D. Megahertz or Gigahertz

Explanation: Processor clock rate measures the number of cycles performed per second, commonly expressed in megahertz (MHz) or gigahertz (GHz).

• A. Input device
• B. Output device
• C. Memory
• D. Microprocessor

Explanation: The microprocessor interprets bit patterns as either instructions or data while executing a program.

• A. Floppy disks
• B. Magnetic disks
• C. Integrated circuits
• D. Logic gates

Explanation: Integrated circuits placed many electronic components on a small chip, greatly reducing computer size and cost.

• A. Volatile storage
• B. Non- volatile storage
• C. Sequential storage
• D. Direct storage

Explanation: Non-volatile storage preserves its contents when electrical power is removed, as with flash memory, SSDs, and hard drives.

• A. does not require constant power
• B. does not use magnetic media
• C. consists of four main types of devices
• D. does not store information for lateral retrieval

Explanation: Secondary storage is non-volatile, so it retains information without continuous electrical power.

• A. RAM
• B. ROM
• C. PROM
• D. EPROM

Explanation: Firmware is non-volatile software that must remain available when power is removed, so it is traditionally stored in ROM.
