Memory trick: Macro = automation.
Correct answer: Mail merge. Mail Merge combines one letter with a list of names and addresses.
Background: It is found in the Mailings tab.
Did you know? It is useful for invitations and letters.
Memory trick: Mail merge = many copies, many names.
Correct answer: HTTPS. HTTPS encrypts the data between your browser and a website.
Background: The S stands for Secure.
Did you know? A padlock icon shows an HTTPS site.
Memory trick: S = Secure.
Correct answer: Protect against unauthorized access and threats. A firewall filters network traffic to block unauthorized access and threats.
Background: Firewalls can be hardware, software, or both.
Did you know? They work like a security guard at a network’s door.
Memory trick: Firewall = protection.
Correct answer: Social engineering attack. Phishing is a social engineering attack that tricks people into sharing private information.
Background: It often uses fake e-mails or websites.
Did you know? Never click links from unknown senders.
Memory trick: Phishing = trick, not code.
Correct answer: DHCP. DHCP automatically assigns IP addresses to devices on a network.
Background: DHCP stands for Dynamic Host Configuration Protocol.
Did you know? A home router usually acts as the DHCP server.
Memory trick: DHCP = Dynamic IP.
Correct answer: Extend RAM by disk space. Virtual memory uses part of the disk as extra RAM when physical RAM is full.
Background: It lets a computer run larger programs than RAM alone allows.
Did you know? It is slower than real RAM.
Memory trick: Virtual = disk acting as RAM.
Correct answer: 32. An IPv4 address has 32 bits, written as four numbers such as 192.168.1.1.
Background: Each of the four numbers is 8 bits.
Did you know? IPv4 can give about 4.3 billion addresses.
Memory trick: IPv4 = 32 bits.
Correct answer: 128. An IPv6 address has 128 bits.
Background: IPv6 was created because IPv4 addresses were running out.
Did you know? It is written in hexadecimal, such as 2001:db8::1.
Memory trick: IPv6 = 128 bits.
Correct answer: SRAM (Static RAM). SRAM (Static RAM) is faster than DRAM and is used for cache memory.
Background: Both SRAM and DRAM lose data when the power is off.
Did you know? SRAM is more expensive than DRAM.
Memory trick: S = Speed (SRAM).
Correct answer: BCC. BCC (Blind Carbon Copy) sends a copy without showing those addresses to others.
Background: Use BCC when sending to many people to protect privacy.
Did you know? BCC stands for Blind Carbon Copy.
Memory trick: BCC = Blind = hidden.
Correct answer: Dennis Ritchie. Dennis Ritchie created the C language at Bell Labs in the early 1970s.
Background: C was used to write the UNIX operating system.
Did you know? C++ was built on C.
Memory trick: C = Ritchie.
Correct answer: RAM. RAM is the main (primary) memory that the CPU uses to run programs quickly.
Background: More RAM helps a computer run more programs smoothly.
Did you know? RAM loses its data when the power is off.
Memory trick: RAM = speed.
Correct answer: Google Drive. Google Drive stores files online in the cloud.
Background: Other examples are Dropbox and OneDrive.
Did you know? Cloud files can be opened from any device with internet.
Memory trick: Drive = cloud storage.
Correct answer: John Blankenbaker. John Blankenbaker built the Kenbak-1 in 1971, which is often called the first personal computer.
Background: Only about 40 Kenbak-1 machines were sold.
Did you know? The Apple I and IBM PC came later.
Memory trick: First PC = Kenbak-1.
Correct answer: Minimize data redundancy. Normalization organises tables to reduce repeated (redundant) data.
Background: It splits large tables into smaller related ones.
Did you know? Common forms are 1NF, 2NF, and 3NF.
Memory trick: Normalize = less repetition.
Correct answer: Developing web pages. HTML (HyperText Markup Language) is used to build web pages.
Background: HTML uses tags such as <p> and <h1>.
Did you know? CSS adds style and JavaScript adds action to web pages.
Memory trick: HTML = web page structure.
Correct answer: Encrypted. Ransomware encrypts the victim’s files and demands money to unlock them.
Background: The name comes from “ransom”, money demanded for release.
Did you know? Regular backups are the best protection.
Memory trick: Ransom → files locked (encrypted).
Correct answer: Allow data to bypass the CPU. DMA lets devices transfer data directly to or from memory without going through the CPU.
Background: This frees the CPU to do other work.
Did you know? Disk drives and sound cards often use DMA.
Memory trick: DMA = direct, no CPU middleman.
Correct answer: An operating system technique that allows more than one program to run concurrently. Multiprogramming keeps several programs in memory so the CPU can switch between them and stay busy.
Background: It improves CPU use.
Did you know? Time sharing is an extension of multiprogramming.
Memory trick: Multi = many programs at once.
